Understanding and quantifying Greenhouse Gases (GHG) emissions is central to international efforts to slow their growth rate in the atmosphere, in order to mitigate the humanitarian and economic impacts of climate change.

The overarching objective of the UK Greenhouse Gas Emissions and Feedback Programme is to deliver improved GHG inventories and predictions for the UK, and for the globe at a regional scale. We are addressing this objective by developing a comprehensive, multi-year and interlinked measurement and data analysis programme, focussing on the major GHGs carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). The Programme integrates three UK research consortia with complementary objectives:

  • GAUGE will produce robust estimates of the UK GHG budget, using new and existing measurement networks and modelling activities at a range of scales. For more details, see GAUGE (Greenhouse gAs Uk and Global Emissions).
  • RAGNARoCC is an oceanographic project to investigate the air-sea fluxes of GHGs in the North Atlantic region, see RAGNARoCC (Radiatively active gases from the North Atlantic Region and Climate Change) for details.
  • GREENHOUSE uses extensive existing UK field data and targeted new measurements to build regional GHG inventories and improve the capabilities of land surface models. See  GREENHOUSE (Generating Regional Emissions Estimates with a Novel Hierarchy of Observations and Upscaled Simulation Experiments) for more details.

The GHG Programme and the three consortia GAUGE, RAGNARoCC and GREENHOUSE are funded by the UK Natural Environment Research Council (NERC).
