Devolved Administration Greenhouse Gas and Air Pollution Inventories

Aether is now leading on the compilation and reporting of greenhouse gas and air pollution inventories for England and the Devolved Administrations, as a part of the wider UK National Atmospheric Emissions Inventory programme.

Aether leads the compilation and reporting of greenhouse gas and air pollution inventories for England, Scotland, Wales, and Northern Ireland, as a part of its role within the wider UK National Atmospheric Emissions Inventory programme. These inventories are a vital evidence-base for policy makers to track progress towards emissions targets, whilst also identifying the priorities for further policy intervention on a regional level. These Devolved Administration inventories are part of the UK NAEI programme, and are compiled and published annually on the NAEI website.

The challenge

Aether is required to publish the greenhouse gas and air pollution inventories annually, following the schedule in the table below.

Reporting obligation Publication deadline
Greenhouse gas emissions datasets for by-source, end-user, and traded / non-traded emissions June
Air pollutant emissions datasets and accompanying report September

The Devolved Administration inventories are based principally on the UK emissions inventory, which uses a wide range of data sources and modelling techniques to estimate emissions of greenhouse gases and air pollutants annually to a high degree of certainty. However, many of these data sources lack enough detail to enable the direct estimate of emissions for England, Scotland, Wales, and Northern Ireland individually. As a result, alternative models and calculations are required to disaggregate the UK-wide figures to each of the Devolved Administrations.

The solution

Aether staff are specialists in the preparation, management, and reporting of emissions inventories. Our team has a wealth of expertise and have significant experience in the development of inventories globally, as well as for the Devolved Administrations. We use this expertise to develop, test, and implement alternative modelling approaches to disaggregate emissions, particularly across the energy supply, domestic, industrial processes, and waste sectors. Our knowledge in this area ensures that the emissions inventories are as accurate and robust as possible. Our transparent approach to our work is appreciated by key stakeholders in each region ensuring the data is used with confidence and purpose.

The result

Aether first led on the publication of the air pollution inventory for the Devolved Administrations in 2021 (link to NAEI report), and, with the support of other members of the NAEI consortium (Ricardo Energy & Environment, UKCEH, Rothamsted Research, Forest Research, ADAS, and Gluckman Consulting) will continue to publish these inventories annually for the next three years.

Aether has been supporting Antigua and Barbuda on their first Biennial Update Report (BUR) by writing the Mitigation chapter. This work will enable Antigua and Barbuda to report transparently on initiatives addressing climate change mitigation and adaptation. Also the climate action database will enable the Department of Environment to take stock of climate related initiatives across the country, including the flow of climate finance, and relate this to national strategies and targets.

Testimonial

Don't just take our word for it...

“ It is always an absolute pleasure working with Aether. I always know what is expected of me. Their work ethic is of a very high standard and projects are always handled in a very professional manner. I have learnt many skills in terms of project management, quality control and workshop training styles from Aether and I hope to carry these principles forward in my own work. I look forward to collaborating with Aether more in the future. ”

Luanne Stevens, Gondwana

“ 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

“ Aether delivered training workshops and generated learning materials for our SSN members, providing technical content in a manageable and comprehendible format. We particularly benefitted from their extensive knowledge and ability to interpret the needs of our members into the training materials. ”
