Impact of the proposed NVZ Action Programme on greenhouse gas emissions

This project assessed the impact of the Revised NVZ Action Programme measures on greenhouse gas emissions.

In 2007 Defra consulted on proposals for revision of the NVZ Action Programme measures, and whether to apply those measures within discrete NVZs (increased from 55% to 70% of England) or throughout the whole of the country. It was necessary to complete a Full Impact Assessment that included an estimate of the impact of the proposals on greenhouse gas emissions. This project addressed the following questions:

  • How each of the proposed measures impacted on greenhouse gas emissions?
  • Which measures resulted in the greatest decrease in emissions?
  • Which measures resulted in the greatest increase in emissions?
  • The overall impact of the proposed Action Programme on emissions?

Objectives

  • To identify which Action Programme measures and associated responses in farmer behaviour could impact on emissions of greenhouse gases.
  • To quantify the effect of the Action Programme measures on emissions of Carbon Dioxide (CO2), Nitrous Oxide (N2O) and Methane (CH4). Impacts were quantified and presented in relation to:
    • individual Action Programme measures,
    • the whole Action Programme, with and without the inclusion of cover crops,
    • the extended NVZs and the whole territory.
