  1. Status of Climate Change Policy Development Issues for Agriculture William Hohenstein Global Change Program Office

  2. Why should farmers and ranchers care about climate change? • Climate variability, and climate change have effects on agriculture and land use. • Agricultural and forest systems are important sources of greenhouse gases and carbon sinks • Forest and agricultural emission reductions and carbon sinks offer potentially significant low-costopportunities to address climate change

  3. Within the US: Agriculture accounts for 7 % of GHG emissions Carbon sequestration offsets 11 % of U.S. emissions U.S. GHG Emissions: 7,260 million metric tons CO2e Fossil Fuel CO2: 80% U.S. Carbon Sequestration: 828.5 million metric tons CO2e Forests: 72% Urban trees: 11% Ag. N2O: 5% Ag. CH4: 2% Agricultural Soils: 5% Wood products: 12% Other: 14% ** Source: US EPA. 2007. Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990 - 2005

  4. Within agriculture: Half of emissions are from livestock and grazing, A third are from cropland nitrogen, and The remainder from energy use and small sources U.S. Agriculture and Forestry Greenhouse Gas Inventory: 2005

  5. Approaches to Greenhouse Gas Regulation • Traditional Command and Control • Regulatory agency sets standards • Specific technologies (scrubbers) • Performance (tons, tons/unit output) • Cap and Trade • Regulatory agency sets overall objective (total allowable emissions) • Allocates or auctions emission allowances • Firms must obtain allowances in order to emit a pollutant • Firms can receive allowances, purchase allowances, or reduce emissions • Cap and Trade with Offsets • Unregulated firms can receive credits for reducing emissions • Regulated firms can purchase offset credits to meet regulatory requirements (“offsetting emissions”)

  6. Why is there interest in Cap-and-Trade? Concept: Regulators set overall limits on emissions (or environmental performance). Firms must have allowances to emit the pollutant. Allowances can be bought, sold, or transferred Attributes: • Establishes clear property rights for pollutants • Taps market forces to efficiently allocate resources to reduce pollution • Provides incentives to innovate • Equates costs of environmental control across all polluters Concerns: • Makes it difficult to address localized environmental damage • Distribution of allowances creates new assets – and transfers of wealth

  7. Traditional Command and Control Regulation Baseline Emissions 100 Tons Emission reduction Firm A Firm B Cost of abatement $100.00/ton $50.00/ton $5,000.00 = $15,000.00 Total cost of abatement $10,000.00

  8. Cap and Trade Regulation Baseline Emissions 100 Tons Emission reduction Firm A Firm B Cost of abatement $50.00/ton $50.00/ton $10,000.00 = $10,000.00 Total cost of abatement $5,000.00 $5,000.00

  9. Cap and Trade Regulation With Offsets Baseline Emissions 100 Tons Emission reduction Firm A Firm B Farmer Cost of abatement $25.00/ton $25.00/ton $25.00/ton = $ 5,000.00 Total cost of abatement $2,500.00 $2,500.00 $5,000.00

  10. Issues with Offsets Offsets are produced by entities that are not regulated: • Would the action have happened anyway? (Additionality) • Will other firms/entities fill gaps if the action results in a drop in production? (Leakage) • What are we measuring benefits against? (Baselines/benchmarks) Carbon sequestration is unique: • Will the carbon that is sequestered and stored be kept out of the atmosphere? (Permanence) Most agriculture and forestry sources and sinks are not well defined “point” sources: • Can we truly assess the benefits? (Measurement uncertainties)

  11. Steps in Determining Carbon Offsets • Determine of eligible practices; • Establish metrics for quantifying greenhouse gas benefits; • Establish reporting requirements; • Provide technical assistance – technical service provision to assist in planning and implementation; • Certify implementation; • Maintain registry of information, recordkeeping, including ensuring against duplicate records; • Conduct audits and spot checks; • Award offsets or issuance of incentive payments; • Monitor against loss of carbon that is sequestered.

  12. How does Waxman-Markey HR 2454 address Agriculture and Forests? Greenhouse Gas Regulation • Sets caps on greenhouse gas emissions from 85% of current sources Offsets • USDA would administer the offsets program; • Caps the use of domestic offsets at 1 billion tons of CO2e per year; • Requires USDA to account for: • Leakage • Additionality • Uncertainties Combined Efficiency and Renewable Electricity Standard Clean Transportation

  13. Costs and Benefits of Climate Change Policy to Agriculture • Three main issues: • Production costs : energy and fertilizer inputs • Offsets/incentives: GHG reduction potential • Renewable energy: Wind, bioenergy • Agriculture is energy intensive: • Fertilizer and fuel costs account for 50-60 percent of variable costs of production for corn; • Because of higher personal transportation expenditures, rural households are more likely than urban households to feel the pinch of increased gas prices. • The costs will be considered against the potential benefits from offsets and renewable energy markets • Lastly, by doing nothing, there will be a cost as well from the effects of warming.
