Feasibility of Green House Gas (GHG) mitigation methods - AC0222

The Committee on Climate Change has responsibility for reviewing and selecting appropriate policies to meet the Climate Change Act (2008) commitment to reduce UK greenhouse gas (GHG) emissions by 80% by 2050 compared to 1990 levels. The agriculture, forestry and land management sector (AFLM) accounts for around 7% of all GHG emissions in the UK and abatement in this sector will contribute to the overall target.
A report by SAC in 2008 (RMP4950) reviewed the UK marginal abatement cost curves for the agriculture, forestry and land management sector to 2022 and a scenario analysis for possible abatement options to 2050. The key outcomes from this report were a list of priority mitigation methods (MMs) for reducing greenhouse gas emissions in the sector based on maximum technical potential (MTP).
Following this report, ADAS conducted an analysis of policy instruments (PIs) for reducing greenhouse gas emissions from agriculture, forestry and land management (AFLM) (RMP5142).This report placed the MMs as defined by SAC within a broad range of policy options to evaluate the potential for policy to deliver emissions reductions.
There were some limitations with the SAC report and these were discussed in the ADAS report. In particular, the reports focused on the uncertainty of mitigation per unit (head/hectares) and extent (potential total head/hectares) and the maximum potential for reducing GHG emissions but there was no detailed analysis of the full costs of their implementation, the cost impacts in different farming systems or the current level of uptake and implementation, and what might make particular mitigation methods more attractive to farmers in different farming systems.
The overall aim of this project is to identify the MMs to reduce GHG emissions in the agriculture sector in England that have the greatest contribution to reduced emissions and to assess their implementation costs and barriers over a range of farm types and sizes in order to provide evidence for policy development.
This is primarily a desk study to identify the most cost-effective MMs based on previous work, and analyse the variation in cost-effectiveness and current uptake for different farm types and sizes. Up to 50 priority MM scenarios (farm type x farm size x mitigation method) will be identified and analysed for cost-effectiveness, practical issues and barriers to uptake. A key part of the study is a farmer consultation through a telephone survey for quantitative information and workshops/in depth interviews, to validate results, provide supporting evidence for levels of uptake and quantitative information on attitudes to the MMs in order to evaluate the barriers to uptake.
7b. Objectives

1. Evaluate and identify GHG mitigation methods (MMs) with lowest costs-biggest potential impact in the agriculture sector.
2. Understand the practical and economic considerations at a farm level (farm types and size). Constraints to prior projects meant that the analysis of specific MMs was restricted to a limited number of farm types and only one size. MMs place specific requirements on a farm but their application may be more appropriate or easier for specific farm types or sizes. The variability in implementation costs over farm type and size has implications for policy.
3. Understand the current level of uptake of MMs. One of the primary causes of the difference between the SAC and ADAS view of the abatement potential of certain MMs was the area over which they could be applied.
4. Identify the main barriers/drivers for changing practice at a farm level and evaluation of implications for maximising GHG mitigation.
