Aether has been providing support to the European Environment Agency through their European Topic Centres since 2014. From 2022 Aether provides support under two new ETCs – the ETC for Climate Change and Mitigation (CM) and the ETC for Human Health and the Environment (HE) – both of which will run until the end of 2026.
An annual work programme is agreed within each ETC, covering many different projects. Our work in these fall into three thematic areas:
Some of the highlights of our work across these areas are summarised here.
Air pollution data
In 2022 this will include support to review and compilation of the EU-27 air pollution inventories under the NECD and the UN/ECE Convention on long-range transboundary air pollution (CLRTAP), and a project to explore the methodologies to estimate the health and environmental impacts of ammonia and methane emissions from the livestock sector. Aether will also be providing support to the 2023 update of the EMEP/EEA Guidebook for air pollution emissions inventories.
Analysis of air pollution policies
Aether supports the reporting and analysis of the air pollution policies and measures (PaMs) reported by EU Member States under the National Emissions reduction Commitments Directive (NECD). This produces a series of products:
The report describes the main characteristics of Member States’ additional air pollutant PaMs reported through the EEA PaM tool as required by Directive the NECD. The report also explores the potential synergies between air pollution and climate PaMs.
In 2021 Aether researched the impact of COVID-19 on Member States’ planned additional air pollution policies and the potential consequences for meeting their reduction commitments.
Aether has been leading work to support the European Commission and the EEA with the streamlining of industrial pollution reporting:
These project websites contain numerous resources (including data models, QA/QC documentation and manuals for reporters) to help reporting countries prepare to use the new data flows:
In 2022 industrial emissions projects include research on the external cost of industrial air pollution, and the contribution of the industrial sector to the 2030 emissions reduction commitments and its role in the long term.

Agricultural climate mitigation policies and measures
This project asked two key research questions: What kinds of policies for the mitigation of agricultural GHG emissions are currently implemented and planned by EU-27 MS, and why have they not effectively reduced overall agricultural GHG emissions? What further actions are needed to reduce EU-27 agricultural emissions? The report is available to read here.
Contact Richard German for more information.
Policies and measures reporting and analysis
These projects provide support to Member States reporting climate mitigation policies and measures (PaMs) under the EU Governance Regulation, analysis of the information reported, and development of a visual presentation of the data. Previously, this has included on anlaysis of topics such as case studies of good practice policy mixes in building energy efficiency, and on PaMs covering renewable energy in the heating and cooling sectors.
Recent publications include:
In 2022 this includes support to the EEA exploring the impacts of climate mitigation policies in the waste sector.
Category: International Organisations, Policies and Measures
Aether, alongside project partners the Stockholm Environment Institute, the UK Centre for Ecology & Hydrology, and Plantlife International, undertook a study for WWF of the nitrogen cycles and pathways in the UK and reviewed existing strategies and policies that could affect the balance of nitrogen in the environment.

The air pollutant emissions inventories for England, Scotland, Wales, and Northern Ireland were published in September 2025. The data covers the period 2005 to 2023, for the pollutants ammonia, carbon monoxide, nitrogen oxides, non-methane volatile organic compounds, PM10, PM2.5, sulphur dioxide, and lead. In addition, experimental inventory statistics are presented for emissions of benzo[a]pyrene, dioxins and furans, and mercury.

Aether completed a project for to train staff in Government of Jersey in using Aether's Carbon Scenario Model to quantify the carbon impacts of net zero policies. The model is a key tool for the Government of Jersey for informing policy decisions on climate actions, and other related policies.

In the first week of October Richard Claxton and Sergii Shmarin were in Istanbul, contributing as lead authors to the upcoming IPCC Methodology Report on Short-Lived Climate Forcers (SLCFs). SLCFs - such as black carbon, and other ozone precursors play a critical role in climate change and air quality. The new methodology report will provide essential guidance for countries to improve their emissions inventories and strengthen climate action.

Aether has recently expanded its Land Development services and secured six new commissions with one of the UK’s top 14 house builders. These projects span from comprehensive Environmental Impact Assessments for large-scale residential developments to focused sustainability, energy, and air quality reports for smaller schemes.
