Economic Potential of Biomass-Based Fuels for Greenhouse Gas Emission Mitigation AgEcon
Schneider, Uwe A.; McCarl, Bruce A..
Use of biofuels diminishes fossil fuel combustion, thereby also reducing net greenhouse gas emissions. However, subsidies are needed to make agricultural biofuel production economically feasible. To explore the economic potential of biofuels in a greenhouse gas mitigation market, we incorporate data on production and biofuel processing for the designated energy crops—switchgrass, hybrid poplar, and willow—in a U.S. Agricultural Sector Model, along with data on traditional crop-livestock production and processing, and afforestation of cropland. Net emission coefficients on all included agricultural practices are estimated through crop growth simulation models or are taken from the literature. We simulate potential emission mitigation policies or markets...

Influences of Permanence on the Comparative Value of Biological Sequestration versus Emissions Offsets AgEcon
McCarl, Bruce A.; Murray, Brian C.; Schneider, Uwe A..
We use a net present value framework to examine the impact of non-permanence on the economics of land-based biological carbon sequestration. Contingent on assumptions about discount rates, management, and carbon prices trajectories, and payment contract design, we find the adjusted value of carbon sequestration relative to permanently available emission offsets to be between 38 and 55 percent for agricultural soil offsets and between 51 and 99 percent for afforestation offsets. Simulations with an Agricultural Sector Model show the empirical effect of sequestration value discounts on the total potential of U.S. agricultural sinks to mitigate greenhouse gas emissions within a multistrategy setting.

Greenhouse Gas Mitigation through Energy Crops in the United States with Implications for Asian-Pacific Countries AgEcon
Schneider, Uwe A.; McCarl, Bruce A..
Agriculture-based biofuels have the potential to replace fossil fuels, thereby offsetting greenhouse gas emissions. We estimate emission abatement supply curves from energy crops switchgrass, hybrid poplar, and willow under a wide range of sectorwide greenhouse gas emission reduction incentives in U.S. agriculture. The Agricultural Sector Model employed captures market interactions of biofuel production with traditional agricultural production and with alternative emission mitigation strategies. U.S. results suggest an increasing importance of biomass-based electricity for carbon mitigation incentives above an economic threshold of $50 per ton. At incentive levels of $170 per ton and higher, emission offsets from energy crops provide the highest net...

Energy Use in Agriculture: A Modeling Approach to Evaluate Energy Reduction Policies AgEcon
Kempen, Markus; Kraenzlein, Tim.
Agricultural production requires significant input of fossil fuels and other energy sources leading to negative external effects like emissions of CO2. Measures to discourage energy consumption in the agricultural sector are contemplated upon and might increase costs of production activities. At the same time, energy cost rise due to market developments, also affecting the relative competitiveness of agricultural activities in favor of low energy input sub-sectors. Increasing energy related cost could reduce total energy consumption, but the extent of the reduction is uncertain. The effects of increasing energy costs in EU27 on market quantities and prices as well as energy use in the agricultural sector will be investigated using the agricultural sector...

Harvesting the Greenhouse through Altered Land Management: Economic Potential and Market Design Challenges AgEcon
Schneider, Uwe A.; McCarl, Bruce A.; Woodward, Richard T..
An Agricultural Sector Model is used to determine the economic potential of agricultural greenhouse gas emission reduction strategies within hypothetical emission mitigation markets. For a complete set of agricultural land management decisions, emissions and emission reductions of carbon dioxide, methane, and nitrous oxide are accounted for and simultaneously subjected to a wide range of carbon prices. The estimated, competitive emission abatement supply functions for major agricultural strategies are contrasted with two other commonly used measures of abatement potential: single strategy economic potential and technical potential. Specific agricultural production and market characteristics that further impact agriculture's mitigation potential are...

Effects of Agricultural Greenhouse Gas Emission Mitigation Policies: The Role of International Trade AgEcon
Schneider, Uwe A.; Lee, Heng-Chi; McCarl, Bruce A.; Chen, Chi-Chung.
The Kyoto Protocol represents the first international agreement to reduce greenhouse gas emissions. Proposed mitigation efforts may involve the agricultural sector through such options as planting trees, crop and livestock management changes, and biofuels production. The combined use of these strategies could substantially reduce net emissions of carbon dioxide, methane, and nitrous oxide. However, countries where the Protocol imposes emissions caps have expressed concern about their competitiveness with countries that are not part of the Kyoto Protocol. In a free-trade arena, food production and exports in unregulated countries could increase and reduce market share for the producers in complying countries. We examine the effects of differential Protocol...

Economic Potential of Greenhouse Gas Emission Reductions: Comparative Role for Soil Sequestration in Agriculture and Forestry AgEcon
Schneider, Uwe A.; McCarl, Bruce A.; Murray, Brian C.; Williams, Jimmy R.; Sands, Ronald D..
We use the Agricultural Sector Model to analyze the economic potential of soil carbon sequestration as one of several agricultural greenhouse gas emission mitigation strategies, including afforestation. For low incentives on carbon emission savings, agricultural soil carbon sequestration is the most cost-efficient strategy. As incentive levels increase above $50 per ton of carbon equivalent, afforestation and biofuel production become the key strategies, while the role of soil carbon diminishes. If saturating sinks are discounted based on their net present value, the competitive economic equilibrium among agricultural mitigation strategies shifts away from soil carbon sequestration and afforestation and toward more biofuel production. Regardless of the...
