Inventory Improvement Project – UK Landfill methane emissions model - WR1124

The UK greenhouse gas (GHG) inventory is split into sectors. One of these is the waste management sector, comprising emissions from landfill, incineration (non-energy) and wastewater treatment. These amounted to 22.7mtCO2e in 2008, of which 20.2mtCO2e was from landfill methane.

Landfill methane emissions are currently modelled, rather than measured, in the UK GHG inventory. Whilst this is necessary, there are uncertainties in the modelling approach. The current model used to predict methane emissions from landfill – MELMod – is a reworking of the previous (Golders) model to make it more user-friendly, rather than a fundamentally different model. It is based on IPCC guidelines.

As part of the Government’s drive to deliver and account accurately for carbon savings Defra and DECC wish to ensure the model reflects all current data and assumptions and ensure all areas of uncertainty that cannot be resolved immediately are understood and the range of possible values estimated.

1. At the end of Phase 1: a project report detailing the areas reviewed and suggestions for improvements, with full justification (including sources/references). The report should review the suggested improvements in light of IPCC guidance and highlight any that would not follow this. Defra and DECC will review these suggested improvements (and peer review this report) to agree the changes to be made to the model.
2. At the end of Phase 2: a fully functional and updated landfill methane emissions model should be delivered, reflecting the agreed improvements and the additional functionality to allow scenario testing.
