Item Open Access A Legal and Economic Analysis of the Tri-State Water Wars(2014-04-25) McCord, John Miller Jr.Water is essential for all human life and, thus, serves as the keystone of any prosperous nation. One can look back thousands of years into the known history of human civilizations and see the evolution (and revolution) of how mankind has come to govern its water. Taking a look around the world, it's easy to see the devastating impacts of inadequate water supply on both human life and the environment, as a whole, but it is more difficult to see the extent to which a water-rich society may take this vital resource, and the way-of-life it has enabled, for granted. The Tri-State Water Wars, as it has come to be known, refers to the collective, on-going series of legal disputes between Georgia, Alabama, and Florida over rights to the shared water resources of the Alabama-Coosa-Tallapoosa (ACT) and Apalachicola-Chattahoochee-Flint (ACF) River Basins. In 2013, the State of Florida filed a lawsuit against the State of Georgia in the Supreme Court of the United States in regard to the waters of the ACF River Basin. This paper will explore some of the most politically, economically, and legally compelling issues embedded in the dispute. All three states have unique claims to the shared waters of the ACF Basin, from Metro Atlanta growing population and demand, to south Georgia’s agricultural irrigation, to Alabama’s nuclear power plant, to Florida’s oysters and endangered species. The Supreme Court will likely decide before the end of the year whether or not they will take the case. If they do take the case, the trial will likely drag out for multiple years; thus, any immediate resolution sought by Florida may be delayed. Regardless of the outcome, each stakeholder in the ongoing Tri-State Water Wars litigation must determine how it will accommodate future demand increases and how future supplies may play a role in meeting this demand.Item Open Access A Program Evaluation of Connecticut Project Learning Tree Educator Workshops(2012-04-27) Sayers, JenniferProject Learning Tree (PLT) is a national environmental education curriculum designed to help formal and informal educators integrate environmental education across disciplines and within the context of state curriculum standards. This program evaluation quantifies the impacts of Project Learning Tree educator workshops on the frequency and quality of environmental education taught in Connecticut. Data was collected through surveys of past Connecticut workshop participants (n=34) and a control group of public school educators (n=445). Analytic methods included negative binomial regression and ordered logit models. Workshop participation was not found to be a significant predictor of the extent or quality of environmental education in Connecticut. Only three variables were found to be significant (α = .05) predictors of increased environmental education in Connecticut’s public schools: educator’s age, educator’s contractual responsibility for science education, and working at a school with an institutional commitment to sustainability. Ordered logit model results also show that science educators have the greatest self-reported confidence levels in integrating environmental education and require the least amount of effort to prepare and teach environmental lessons.Item Open Access An Analysis of the Privatization of Drinking Water Facilities in the United States(2011-04-29)The drinking water infrastructure in the United States faces significant underinvestment. The 2009 American Society of Civil Engineers Report Card on America’s Infrastructure gave a D minus for the Nation’s drinking water infrastructure. In a 2007 study, the EPA found a 20-year investment gap of $334.8 billion. Degrading infrastructure and constrained finances have led cities and municipalities to consider selling, or privatizing, their drinking water services to for-profit companies. Debate regarding the efficiency of public or private ownership lacks sufficient quantitative analysis to address two major concerns: water prices and infrastructure investment. Previous studies quantifying the impacts of ownership on drinking water utilities are dated or lacking financial analysis. This study uses survey data from 2002-2008 provided by the American Water Works Association and National Association of Water Companies. Quasi-experimental design methods and statistical regression analysis provide a causal link between ownership and employment levels, operating revenue, and infrastructure investment. Results of this study show ownership to have a significant impact on operating revenues and number of employees at a facility. Specifically, private ownership will increase operating revenues and decrease facility-staffing levels. However, public facilities regulated in a similar manner to private facilities show no statistical difference from private ownership regarding employment numbers. Ownership does not have a significant effect on infrastructure investment as approximated through depreciation expense and planned capital expenditures. Analysis of the results emphasizes ownership to be neither the savior nor the downfall to issues in U.S water management. This study suggests policy-makers and advocates shift focus away from debate regarding privatization towards the proper management of water infrastructure. Future studies would benefit from analyzing management structures and incentives at drinking water facilities.Item Open Access An Analysis of the Program Assessment Rating Tool: Measuring the Performance of Federal Environmental and Natural Resource Programs(2011-04-29) Buell, Nicole; Tortorella, JohnInterest in, and use of, performance evaluation tools in the federal government has increased over the past two decades as a mechanism to gauge the effectiveness of federal programs. An effective evaluation system can improve government performance in many ways including boosting outcomes, strengthening accountability, and enhancing process transparency. A well-developed and consistently applied performance evaluation system can also assist in the identification of programs that excel and those that do not achieve their intended results. This research aims to analyze one such performance evaluation tool, the Office of Management and Budget’s Program Assessment Rating Tool (PART), by examining a subset of programs concerned with the environment and natural resources. The objective of this study is to evaluate the effectiveness of PART as a means to hold agencies accountable for their performance. This objective is accomplished by examining the quality of goals, measures, and evidence provided by programs in their PART reviews as well as the relationship between PART rating and budgetary allocations. Focusing on the set of 167 natural resource and environmental program PARTs, no correlation was found between improved PART scores and budgetary allocations. Significant correlations between PART ratings and evidence and program measures were found. We conclude from this research that future performance evaluation mechanisms should focus more closely on program outcomes, while increasing understanding within agencies of the performance evaluation process and improving transparency for all parties.Item Open Access AN EVALUATION OF CORPORATE VOLUNTARY CLIMATE ACTIONS: A FOCUS ON THE RENTAL CAR & TRUCK INDUSTRY(2010-04-30T02:28:31Z) McCorkle, BetsyClimate change is a global problem with social, economic, and environmental consequences, resulting primarily from reliance on fossil fuels like coal and oil. In the absence of federal climate policy, some companies have taken the initiative to voluntarily take actions to measure and disclosure their carbon emissions and related climate actions. A non-profit organization, Climate Counts, believes that business has the power to change the outcomes related to climate change, and consumers have the power to change business. Climate Counts provides a scoring system, which is an effort to bring consumers and companies together in the fight against climate change. By providing a score of 0-100 to individual companies, Climate Counts compares companies with industries on their published and documented commitments to address climate change. This Master’s Project develops the scorecard for the rental car and truck industry. The evaluation includes six companies in the rental car and truck industry, all of which have annual revenues of over one billion dollars. The scores for the six companies varied from zero to 24 with a median score of 18.5. While the top score of 24 held by the Avis Budget Group and Penske demonstrates that they are their industry’s leaders in corporate climate actions, the relatively low score also indicates that car rental industry has room for significant improvements in voluntary climate change action. Companies that choose to utilize and respond to this evaluation are leading the charge in one of the fastest growing corporate disciplines. They have the willingness to develop and implement a climate strategy that works for executives, employees, customers, and other stakeholders.Item Open Access Attracting Investment to REDD+: Capitalizing on Co-Benefits?(2014-04-25) Poirson, Evan; Hartman, Ashley; Hoagland, Chris; Yu, MichaelAt its inception in 2007, the United Nations-sponsored Reducing Emissions from Deforestation and Forest Degradation (REDD+) mechanism had one primary goal: to mitigate carbon dioxide emissions from the global forest sector, which currently account for approximately 10% of global carbon emissions. REDD+ has undergone various modifications to its scope and approach in the succeeding nine years, but little has yet come from subsequent UN climate negotiations in the way of creating an obligatory financing scheme that would require participation from actors in developed countries. Today, dozens of preliminary REDD+ projects are operational across the world, but these projects receive strictly voluntary funding from a suite of public and private actors, including national governments and companies engaged in social responsibility practices. Despite some successes in this voluntary realm and promises of REDD+ advancement at recent negotiations, it has become clear that without assured funding – and pending an international financing mechanism for REDD+ – projects face an increasingly difficult environment for attaining capital resources. Scaling up the mechanism will be virtually impossible without addressing the imbalance between supply and demand for REDD+ credits in the voluntary stage. Code REDD, a San Francisco-based non-governmental organization whose mission is to support and scale the REDD+ mechanism, is attempting to discover whether untapped opportunities exist for sustaining REDD+ before the commencement of an international financing scheme, specifically by capitalizing on the co-benefits of REDD+ projects: the social and environmental outcomes that inherently accompany responsibly designed carbon offset projects. These co-benefits can include biodiversity benefits, freshwater provision, community economic development, and women’s empowerment. This question of the potential for co-benefit quantification and sale as a means to sustain REDD+ in the voluntary phase was the foundation of the research we undertook here. We aimed to determine how REDD+ stakeholders envisioned the role of co-benefits within the financing of REDD+, and if further efforts to quantify and sell them could bear meaningful results for the future of the mechanism. Splitting the REDD+ community into two distinct categories – practitioners (those who design, implement, and monitor REDD+ projects) and investors (both those who purchase REDD+ credits and those who invest in REDD+ projects) – we held more than twenty interviews to determine the answer to the above question. We found that, though co-benefits were considered an important – even indispensable – part of REDD+ success, few practitioners or investors were interested in their further quantification or expected that voluntary REDD+ could be sustained based on such action. That said, many current and potential investors offered insight into how the business case for REDD+ could be better articulated in order to attract more investment. Also, in speaking with practitioners, we identified ways that the mechanism could be better integrated with other contemporary environmental efforts, including biodiversity offsetting and water funds, offering what we believe could represent partial solutions to the REDD+ demand shortfall.Item Open Access CGE Model Based Natural Gas Tax Exemption Analysis in Beijing Area with Emphasis on Social Welfare and Energy Usage(2017-04-26) Cheng, YanActing as a cleaning and great efficiency fuel, natural gas has gained more and more notice. Reflect on the low percentage of natural gas usage in China, how to motivate natural gas production and usage from macroeconomic view worth discussing. Although carbon tax can be efficiently used to promote carbon emission reduction, the implementation of levying carbon tax might negatively impact natural gas industry and other clean energy industry. Based on this, with the employment of CGE theory, this paper applies GAMS advanced modeling system to construct a CGE model which takes natural gas tax exemption as the target, and takes Beijing as an example to simulate and analyze the impact of gas tax exemption policy on carbon emissions, economic system and social welfare. The paper reveals that the exemption of natural gas might be a possible choice which can control the CO2 emission in Beijing to a certain extent. At the same time, it has a positive impact on the macroeconomic variables and social welfare of the residents in Beijing. Therefore, I suggest that during the early periods of the design and implementation of carbon tax, the protection of natural gas industry can be considered.Item Open Access Closing the "Energy-Efficiency Gap": An Empirical Analysis of Property Assessed Clean Energy(2012-04-26) Kirkpatrick, Aubrey Justin; Kirkpatrick, Aubrey JustinUntil federal regulators halted operations, a handful of municipal PACE programs across the US offered property-secured loans from city or county funds to homeowners for residential clean energy investments. These loans, repaid through property tax assessments, addressed multiple non-price “market barriers” to residential investments commonly identified in the literature on the “energy-efficiency gap” – information barriers, transferability of investment, and cognitive failures common to high up-front cost investments. To elucidate the magnitude of the “energy-efficiency gap”, this analysis uses difference-in-differences models as well as a synthetic counterfactual to estimate the effect on residential photovoltaic installation rates of three California PACE programs operating between 2008 and 2010. When applied statewide, results predict an increase in installations by approximately 25 homes per year for an average-size Californian city, or 14,170 installations per year statewide.Item Open Access Closing the “Energy-Efficiency Gap”: An Empirical Analysis of Property Assessed Clean Energy(2012-04-27) Kirkpatrick, Aubrey JustinUntil federal regulators halted operations, a handful of municipal PACE programs across the US offered property-secured loans from city or county funds to homeowners for residential clean energy investments.

Recent data suggest that approximately 40% of residential households in California from years 2012 to 2016 are occupied by renters. The prevalence of renting along with increasing awareness of evictions make studying the causes of eviction a topic of interest for public officials, scholars, housing service providers, and the renter population among others. High cost of living is a direct common cause of evictions across the US. This paper examines and presents a study on the connection between energy burden (how much a single household pays for electricity out of its total household income) and eviction rate. Analysis relies on the application of quantitative research methods using census tract level data from 2012 to 2016 over the service territory of Southern California Edison (SCE). This study uses models that account for both time-variant and time-invariant effects of other key cost and household demographic variables on eviction rate. By taking this approach, the author attempts to separate an unbiased effect of energy burden, which could inform predictions about whether high energy burden is generally accompanied by high eviction rates. Preliminary results suggest that there is a borderline significant positive correlation between energy burden and the unobserved time-invariant census tract level heterogeneity that contributes to higher eviction rates.Item Open Access Cost-Benefit Analysis of a Green Infrastructure Project for Water Management in Peru(2018-04-23) Aldana, GloriaThe purpose of this research is to analyze the costs and benefits of a “green infrastructure for water management” project in Peru in comparison to a traditional microreservoir. The costs and benefits of the two water management solutions are analyzed in Peru’s developing country context. Green infrastructure entails restoring an ecosystem for storm water management. In this case, cattle will be excluded from an overgrazed area in Huamantanga, Peru. Cattle exclusion is expected to allow for soil decompression. Once the begins to decompress, alfalfa can be grown as cattle pasture and reduce erosion. Together, these effects would increase water storage in the wet season and reduce flooding downstream. The water stored may then be used for irrigation of alfalfa in the dry season. The main economic benefit being studied is the additional income from artisanal cheese production in Huamantanga as a result of the augmented water flow in the dry season. This research will contribute information to the sparse existing green infrastructure literatureItem Open Access Costs and Emissions Reductions from the Competitive Renewable Energy Zones (CREZ) Wind Transmission Project in Texas(2011-04-29) Kwok, Gabriel; Greathouse, TylerWind power has the potential to significantly reduce air emissions from the electric power sector, but the best wind sites are located far from load centers and will require new transmission lines. Texas currently has the largest installed wind power capacity in the U.S., but a lack of transmission capacity between the western part of the state, where most wind farms are located, and the major load centers in the east has led to frequent wind curtailments. State policymakers have addressed this issue by approving a $5 billion transmission project, the Competitive Renewable Energy Zones (CREZ), which will expand the transmission capacity to 18,456 MW by 2014. In this paper, we examine the impacts of large-scale wind power in ERCOT, the power market that serves 85% of the state’s load, after the completion of the CREZ project. We assess the generation displaced and the resulting emissions reductions. We then examine the public costs of wind to estimate the CO2 abatement cost. We develop an economic dispatch model of ERCOT to quantify the generation displaced by wind power and the emissions reductions in 2014. Since there is uncertainty about the amount of new wind developed between now and 2014, three wind penetration scenarios were assessed that correspond to wind supplying 9%, 14% and 21% of ERCOT’s total generation. In the 21% wind energy penetration scenario, the CREZ transmission capacity is fully utilized, and wind displaces natural gas 74% of the time and coal 26% of the time. This results in CO2, NOX, SO2 and Hg emissions reductions of 19%, 17%, 13%, and 15%, and a CO2 abatement cost of $60 per ton of CO2. Lower wind penetrations result in gas being displaced more frequently, lower emissions reductions and an abatement cost up to $91 per ton of CO2. Our results should be compared with other technologies and policies so that policymakers can cost-effectively reduce emissions.Item Open Access Cracking the Ice on Arctic Oil and Gas Exploration(2015-04-24) Hayes, MeganThe Arctic, abundant in hydrocarbon resources, has been considered by the oil and gas industry to be the next big play. The potential resources are expected to challenge if not trump those available in the Middle East. As the arctic regions melt due to a warming climate, the previously treacherous and inaccessible regions are suddenly enticing enough to allow exploration for the very hydrocarbon resources that are largely responsible for the warming trends, creating the so-called Great Arctic Paradox. The paradox increases pressure to choose between competing goals—reduce climate change impacts or increase energy independence and expand energy supply outside of OPEC nations. These tensions are not new, and indeed are playing out in the United States in a variety of other arenas including in debates over hydraulic fracturing and offshore oil leasing off the East Coast of the U.S. However, the fragile nature of the Arctic ecosystem and the numerous state and non-state actors in the Arctic makes these tensions even more acute. In this Master’s Project I highlight these tensions and assess the economic and ecological feasibility and desirability of oil and gas exploration and extraction in the Arctic. To do this I review the climate science and ecology of the Arctic environment and how this is likely to be impacted by oil and gas exploration. I then examine the economic drivers of demand for Arctic energy, in particular forecasts for prices for oil and gas and for competing energy sources. Finally, I examine several models of policy options to reduce climate impacts, translate these policies into impacts on prices for oil/gas, and assess what impact different policies might have on the desirability of Arctic energy exploration. Results of the analysis suggest that while Arctic oil and gas resources are abundant, the value of the unique Arctic ecosystem, combined with lower expected prices for oil and gas and expectations of climate policies that will further decrease demand for oil and gas, make the economic case for Arctic extraction weak.Item Open Access Electrification of Transportation: A Study of the Electric Vehicle Industry in China(2011-04-28) Shao, ShuaiThe world transportation industry is experiencing a significant transaction with the emergence of new technologies in alternative energy. Among different technologies, the electric vehicle (EV) is considered to be the future trend of transportation that could replace the use of hydrocarbons fuels completely as well as reduce emission to zero. The development and commercialization of EV will have a great influence on the landscape of transportation energy in the next decade. This project assesses the current situation and future development of the EV industry in China, focusing on economic analysis and population projection. Based on market research, the study identifies the opportunities as well as challenges for China’s EV industry. Strong government support and large power battery industry are the comparative advantages for the EV industry in China. Currently, charging technology and accessibility to charging stations are the major bottleneck that hinders the commercialization of EV. Lifecycle costs analysis of different EV types was conducted to study the economic competitiveness of EV, and the results show that with government subsidies hybrid electric vehicles and plug-in hybrid electric vehicles are economically competitive in China’s vehicle market. The next 10 years will be an important phase for EV’s market penetration. According to projection, EV will account for more than 8.8% of total vehicle population in China, by the end of 2020.Item Open Access Essays in Energy and Environmental Economics(2019) Kirkpatrick, Aubrey JustinThis dissertation is comprised of three papers which examine important topics in energy and environmental economics. The first paper ("Averting expenditures and desirable goods: Consumer demand for bottled water in the presence of fracking" with T. Robert Fetter) estimates household willingness to pay to avoid consuming tap water when hydraulic fracturing is present in the area. The paper focuses on accounting for the joint production of utility inherent in bottled water. Furthermore, it introduces a novel estimation routine which accounts for household heterogeneity in a parsimonious manner, and provides evidence of its effectiveness. The empirical results of the paper show that accounting for the utility that households have for bottled water independent of fracking results in a lower bound of willingness to pay to avoid one of the primary sources of fracking impacts.
The second chapter ("Estimating Congestion Benefits of Batteries for Unobserved Networks: A Machine Learning Approach") examines the price effect of grid-scale energy storage. Policy-makers have often identified energy storage as a ``solution'' to the intermittency cost of renewables, but no previous empirical work exists to establish the magnitude of that effect, largely because the price effect of energy storage is not constant across a grid and data on grid structures are not publicly available. This paper estimates the cross-network effects of storage and uncovers the network structure relevant to calculating the total reduction in the cost of serving load.
The final chapter ("Heterogeneous Environmental and Grid Benefits from Rooftop Solar and the Costs of Inefficient Siting Decisions" with Steven Sexton, Robert Harris, and Nicholas Muller) calculates the total reduction in pollution externalities associated with a solar panel across each US zip code. Noting that the marginal plant displaced by a solar panel's generation will depend on the location and time of generation, this paper establishes the chain from panel generation to plant displaced to reduction in emissions to reduction in externalities. Results indicate that subsidies and incentives offered by many states do not coincide with the areas where solar panels generate the largest reduction in externalities.
Each of these papers has important implications for energy and environmental policy in the United States and beyond. Valuing the change in overall social welfare from a new technology (e.g. fracking, energy storage, solar) provides a vital understanding that speaks to the economic efficiency of our energy systems, and helps to provide data and intuition for policymakers who seek to maximize total social welfare. In the first paper, valuing the disamenity of fracking helps policymakers understand the optimal regulation of fracking activity. In the second, estimates of energy storage's reduction in the cost of serving load help to guide debate of future policy. And finally, a better understanding of the siting of solar helps to guide future investments in clean energy technology.
Item Open Access Estimating the effect of hypoxia on economic rents from the brown shrimp fishery in the Gulf of Mexico(2011-04-28) Kociolek, ErikaThe overall goal of this analysis is to quantify the effect of hypoxia on economic outcomes of interest, including catch, revenue, catch per unit effort (CPUE) and revenue per unit effort (RPUE) for the brown shrimp fishery in the Gulf of Mexico using spatially explicit data. To isolate the effect of hypoxia on fishing outcomes from confounding factors, we use spatial and temporal variation of hypoxia and take advantage of additional variation: the presence of areas with little to no hypoxia close to areas greatly affected by hypoxia. We employ a differences-in-differences-in-differences (DIDID) estimator, controlling for potential cofounders, including the brown shrimp life and growth cycle and state policies, to isolate the true treatment effect. We find that seasonal hypoxia has a positive, statistically significant effect on catch, revenue, CPUE and RPUE. Estimates of this effect on catch and revenue range from a 62% - 86% increase for seasonal hypoxia and a 63% - 73% increase for persistent hypoxia. For CPUE and RPUE, estimates of this effect range from a 32% - 39% increase for seasonal hypoxia and a 36% - 47% increase for persistent hypoxia. However, when we regress catch of different “classes,” or sizes, of shrimp, our results indicate that landings of large shrimp decrease in the presence of persistent and seasonal hypoxia whereas landings of small shrimp increase significantly. These findings corroborate studies of the effect of hypoxia on shrimp at the organism and population levels, and the estimated effects are consistent for multiple variants of a basic regression model.Item Open Access Evaluating Expected Electric Generation Technology Cost and Risk: Applying Modern Portfolio Theory to North Carolina Electric Power Generation(2007-12-06T14:52:36Z) Rodehorst, AaronEfforts to diversify electric generation technology and fuel sources have received increased attention from state and federal policy makers. To what end and at what cost electric generation diversity should be pursued has been a point of contention in North Carolina. The North Carolina Utilities Commission has declined to adopt the diversity standards expressed in the 2005 Energy Policy Act, but the North Carolina General Assembly and Governor explicitly stated their intent to diversify electric generation technologies and fuels with the passage and enactment of Session Law 2007-397. Session Law 2007-397 requires renewable energy to account for 7.5 percent of electric utilities’ retail sales by January 1, 2018. This study aims to assess diversification’s role in building least-cost electric generation portfolios. To gain further insight into potential least-cost electric generation portfolios, decision-makers can employ modern portfolio theory. Since the 1950s, investors have used modern portfolio theory to reduce a stock portfolio’s risk through the selection of stocks whose returns do not move exactly together. Modern portfolio theory has also been applied to real asset portfolios, and this study uses mean-variance analysis to locate minimum cost electric generation portfolios given historical cost risk and proxy measures. The results reveal Session Law 2007-397 may create electric generation portfolios with lower expected risk than projected electricity portfolios absent a renewable portfolio standard. Wind and to a lesser degree, new biomass resources, play a pivotal role in expected cost and risk reduction; they exhibit lower investment cost risk and no or weak positive correlations with coal and nuclear fuel costs. Natural gas electric generation reduces expected portfolio risk in particular portfolios, because its fuel cost risk is negatively correlated with coal and nuclear fuel costs. Existing coal and nuclear electric generation is difficult to replace, because both electricity sources exhibit low expected cost and risk.Item Open Access Evaluating Viability of Community Solar Microgrids for Resilience in Puerto Rico(2019-04-26) Deng, Simeng; Hansen, Asger Victor; Hiltbrand, Galen; Maddex, Sean; Sinclair Lecaros, SantiagoHurricane Maria, which hit the Caribbean two weeks after Hurricane Irma in September 2017, caused the largest electricity blackout in U.S. history. After the hurricanes, Toro Negro, a rural community nestled into the mountains of Puerto Rico went without electricity for a staggering 8 months. This experience led the community to build and manage Puerto Rico’s first fully operational community solar microgrid to gain electricity reliability and resilience. The aim of this project is to develop an effective management strategy for community solar microgrid systems in Puerto Rico. Our team established a price rate at which the residents of Toro Negro can pay for their electricity and an operations and maintenance plan to ensure the microgrid remains economically feasible for the lifetime of the system. Additionally, we have established a common governance strategy and policy recommendations for microgrids in Puerto Rico. Our project can serve as a blueprint for other communities looking to transition to clean energy and increase storm resiliency.Item Open Access Examine Agricultural Land Use Practices and Their Effects on Carbon Storage and Flux in the United States(2022-04-22) Wang, Hongyi; Luo, ZhixianThe terrestrial ecosystem has provided a net carbon sink, equal to 20% of total greenhouse gas (GHG) emission from industrial activities in the past three decades, yet many land use activities, mainly agriculture, can drastically change natural land carbon flux. We worked with Resources for the Future (RFF) on the Carbon and Land Use Model (CALM) that helps with evaluating the effects of policy decisions on land use and relevant carbon flux changes. To evaluate potential approaches for estimating accurate carbon fluxes from agricultural land use practices, our team first conducted literature review to ascertain carbon flux from different land use changes along with detailed examination of the EPA GHG Emission inventory report 2021 and the 2006 IPCC Guidelines for National Greenhouse Gas Inventories. Then, we identified and assessed data knowledge gaps in existing methods of emission estimation and carbon fluxes modeling. Finally, recommendations were provided to RFF on how the CALM model can be further developed and utilized.Item Open Access Forestry Carbon Assets under California AB 32: Current Business Practices, Future Viability and Ancillary Benefits(2017-04-27) Schwartz, AlexisThe primary objective of this study was to conduct an encompassing analysis of current forestry carbon offset business practices under California A.B. 32. This study goes beyond the critiques of the forestry carbon offset approach and highlights current business practices, examines fringe benefits, and hypothesizes the viability for small and large landowners moving forward. ARB faces an issue when it comes to large and small landowners: to require immense reporting deters TIMOs and large landowner companies, while having such high transaction costs deters small land-owners from engaging in climate change mitigation tactics, but the asset proves itself to be a worthy investment going beyond climate change mitigation tactics and entering a realm of biodiversity conservation and improving community economic development. Thanks to an industry wide survey, the business practices of this newly developed asset are becoming clear and showcases future business strategy plays.
