Aether to support world-leading UK Government emissions inventory

11 February 2025

We’re thrilled to announce our continued work under the newly awarded 10-year contract for the National Atmospheric Emissions Inventory (NAEI).

The NAEI is made up of the Greenhouse Gas Inventory (GHGI) and the Air Quality Pollutant Inventory (AQPI). It provides estimates of annual pollutant emissions for the UK from 1970 to the most current publication year for the majority of pollutants. The data is generated via a common database system that ensures that inventory and projection emission estimates from the NAEI across all pollutants are consistent, drawing on the same underpinning activity data, emissions and emission factor data resources and hence emissions data per source, whether GHG or AQ, are based on a consistent scope and the best available UK activity and emissions data. For further information, please see: https://naei.energysecurity.gov.uk

As part of this programme, Aether will be leading:

  • The compilation of the Company Reporting GHG factors
  • Air Pollution projections
  • The Devolved Administrations inventories
  • Rail emissions
  • Emissions in the Overseas Territories & Crown Dependencies (OTCDs)
  • A new coordination group streamlining inventory work across multiple contracts under the NAEI

We’re proud to contribute to the ongoing development of this world-leading inventory programme, ensuring robust data informs climate and air quality action.

“ Aether was a great asset in involving/engaging with Member States experts on highly technical subjects regarding GHG reporting. Very clear communication of issues and results. ”

Andreas Pilzecker, DG CLIMA

“ Aether is a great partner for work in the area of European Air Emissions. The team was committed, reliable, well organised and had a deep technical understanding and motivated other partners with their good spirit. ”

Umweltbundesamt: Environment Agency Austria

“ We have worked with Aether since 2019 to baseline, and subsequently update, our council and borough greenhouse gas inventories. It is a pleasure working with Aether’s professional, responsive, collaborative and helpful team. ”

Merton Council

“ From their winning bid to final delivery, Aether's work with North Norfolk District Council was positive and thorough. They brought a clear understanding of the challenges local authorities face regarding carbon emissions and quickly understood the unique nature of the Coastwise project. Communication was effective, and the outcomes combined a depth of research with real-world utility for the council's activities around carbon emissions and mitigation. ”

Alastair Zangs, North Norfolk District Council

“ The professional service provided by your company was of very high quality and completed within agreed timelines. ”
