With the Agricultural Ecosystems Program Team
New York State alone, contributes nearly 1% of global greenhouse gas emissions.
US EPA, Energy CO2 inventories
Forest - 62%
Agriculture - 26%
Residential - 6%
Milk is the leading agricultural product in the state
12 billion poundsof milk was produced in 2003
Milk value of $1.56 billion in cash receipts.
New York is the nations 3rd leading milk producer.

Methane and Nitrous Oxide contribute
75% of total farm Global Warming Potential (GWP)
NY Dairy contributes 2.6% of NY Total Emissions
agriculture 8 %

Pataki greenhouse gas report
1) Corn growers can optimize nitrogen application to reduce:
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
in Climate Change Mitigation?
Can agriculture reduce total GHG’s by movinginto the energy sector and producing renewable bio-fuels?
