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


New York State alone, contributes nearly 1% of global greenhouse gas emissions.

US EPA, Energy CO2 inventories


Land greenhouse gas emissions.Use in NY 1992

Forest - 62%

Agriculture - 26%

Residential - 6%


NY Dairy Economics greenhouse gas emissions.

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.

Some Perspective: greenhouse gas emissions.

NY Dairy contributes 2.6% of NY Total Emissions

US average

agriculture 8 %

waste 4 %

industry 31%

Pataki greenhouse gas report


ON FARM greenhouse gas emissions.MITIGATION STRATEGIES

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


Question: Can Agriculture Find Economic Opportunity greenhouse gas emissions.

in Climate Change Mitigation?

Can agriculture reduce total GHG’s by movinginto the energy sector and producing renewable bio-fuels?


Opportunities for Agriculture to Mitigate Climate Change: greenhouse gas emissions.Replacing Fossil Fuels with

Renewable, Carbon Neutral BIOFUELS

Agriculture for food, feed, fiber and FUEL

At the end of the day, we are all consumers. greenhouse gas emissions.

Conservation and efficiency are key


Summary: Dairy in NY state greenhouse gas emissions.

  • 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 MMTCO2e

  • NY agriculture contributes ~2% of NY GHG emissions


Summary: Mitigation Options greenhouse gas emissions.

  • Optimize nitrogen use

  • Optimize animal feeding

  • Investigate manure biogas

  • Farming for carbon neutral, renewable energy

  • Efficiency of use

  • Conservation
