2007-2008: Impact of the
proposed NVZ Action Programme on greenhouse gas emissions (Ref.
WT0757NVZ)
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; and the overall impact of the
proposed action programme on emissions? The objectives were: to
identify which Action Programme measures and associated responses in
farmer behaviour could impact on emissions of greenhouse gases; and 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, and the extended NVZs and the whole territory.
