Compilation and Reporting of the National Atmospheric Emissions Inventory (NAEI), and the Quality Assurance/Quality Control of the NAEI

Tender description

The contract is the delivery of the National Atmospheric Emissions Inventory (NAEI) to generate high-quality and consistent greenhouse gas and air pollutant emissions estimates for the Department for Energy Security & Net Zero (DESNZ), the Department for Environment, Food & Rural Affairs (Defra), the Office for National Statistics (ONS) and the Devolved Administrations in order to meet international reporting requirements and provide scientific evidence for domestic mitigation policies. The GHGI is the UK’s official record of its GHG emissions, which is a statutory requirement under the Climate Change Act of 2008, the UNFCCC and the Paris Agreement. This contract is business critical for tracking progress towards net-zero greenhouse gas emissions as mandated under the Climate Change Act 2008 and the Climate Change Act 2008 (2050 Target Amendment) Order 2019. Similarly, the AQPI is used to fulfil the UKs legal obligation to report annual emissions estimates and projections of air pollutants under the National Emissions Ceilings Regulations (NECR) 2018, and to the United Nations Economic Commission for Europe (UNECE) under the Convention of Long-range Transboundary Air Pollution (CLRTAP). The AQPI is business critical for Defra as it is used to track progress against legal emission reductions commitments under the aforementioned legislation. Lot 1: The NAEI contract will support the production of the UK’s Greenhouse Gas Inventory (GHGI) and the Air Quality Pollutant Inventory (AQPI) respectively and is jointly funded by DESNZ, Defra and ONS. The NAEI contract will support the production of the UK’s Greenhouse Gas Inventory (GHGI) and the Air Quality Pollutant Inventory (AQPI) respectively and is jointly funded by DESNZ and Defra. In addition to the core NAEI, there will be an independent function for independent quality assurance/quality control of the NAEI. This may be considered as a separate lot. If so, bidders will not be able to bid for both lots. The outputs of the GHGI reinforce the UK’s commitment to climate change mitigation. They also provide evidence of designing and evaluating mitigation policy so it is expected that an inventory in some form would be required even if there were no international requirement. Defra has a legal obligation to report UK annual emissions estimates and projections of air pollutants under the National Emissions Ceilings Regulations (NECR) 2018, and to the United Nations Economic Commission for Europe (UNECE) under the Convention of Long-range Transboundary Air Pollution (CLRTAP). Defra use the AQPI not just for meeting its statutory reporting obligations, but also to track progress with its legally binding emission reduction commitments.
