On farm opportunities to reduce greenhouse gas emissions in new york state

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

US EPA, Energy CO2 inventories

LandUse in NY 1992

Forest - 62%

Agriculture - 26%

Residential - 6%

NY Dairy Economics

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.

ON FARM 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

in Climate Change Mitigation?

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

At the end of the day, we are all consumers.

Conservation and efficiency are key

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 MMTCO2e

  • NY agriculture contributes ~2% of NY GHG emissions


On farm opportunities to reduce greenhouse gas emissions in new york state

Summary: Mitigation Options

  • Optimize nitrogen use

  • Optimize animal feeding

  • Investigate manure biogas

  • Farming for carbon neutral, renewable energy

  • Efficiency of use

  • Conservation
