1 On Farm Opportunities to Reduce Greenhouse Gas Emissions in New York State Jenifer Wightman T. Wise, S. Vergara, A. Buttel, J. Gaunt, J. Duxbury, Cornell University With the Agricultural Ecosystems Program Team

2 New York State alone, contributes nearly 1% of global greenhouse gas emissions. US EPA, Energy CO2 inventories

3 Residential - 6% Forest - 62% Agriculture - 26% Land Use in NY 1992

4 Milk is the leading agricultural product in the state 12 billion pounds of milk was produced in 2003 Milk value of $1.56 billion in cash receipts. New York is the nations 3 rd leading milk producer. NY Dairy Economics

5 GOALS Assess Energy Inputs for the Dairy System Evaluate Greenhouse Gas Emissions from the NY Dairy Industry Identify Strategies for Agriculture to Mitigate Emissions

10 Some Perspective: NY Dairy contributes 2.6% of NY Total Emissions US average agriculture 8 % waste 4 % industry 31% Pataki greenhouse gas report

11 1) Corn growers can optimize nitrogen application to reduce: 1) costs 2) nitrogen leaching 3) energy inputs 4) nitrous oxide emissions A 30% reduction in N application equals ~0.16% of total NY state emissions 2) Dairies can investigate manure biogas to capture methane A 50% reduction of CH4 from manure equals ~0.25% of total NY State emissions 3) Dairies can optimize feed to further reduce enteric methane ON FARM MITIGATION STRATEGIES

12 Can agriculture reduce total GHG’s by moving into the energy sector and producing renewable bio-fuels? Question: Can Agriculture Find Economic Opportunity in Climate Change Mitigation?

13 Opportunities for Agriculture to Mitigate Climate Change: Replacing Fossil Fuels with Renewable, Carbon Neutral BIOFUELS Agriculture for food, feed, fiber and FUEL

15 FARM OPTION FOR GHG MITIGATION 30% reduction in N application0.16% 50% capture of manure Methane0.25% ¾ cord/ac cull wood on farm woodlands0.58% Reed Canary grown on CRP and ‘other’ ag land0.97% Mitigation Potential (for 2000 NY total)1.96%

16 At the end of the day, we are all consumers. Conservation and efficiency are key

17 Summary: Dairy in NY state NY state contributes 1% of global GHG emissions NY state provides 12 billion pounds of milk to society with a value of $1.56 billion NY dairy contributes 6.5 MMTCO 2 e NY agriculture contributes ~2% of NY GHG emissions

18 Summary: Mitigation Options Optimize nitrogen use Optimize animal feeding Investigate manure biogas Farming for carbon neutral, renewable energy Efficiency of use Conservation
