What Aether does
Aether Limited is a privately-held UK environmental consultancy headquartered in Oxford, founded in 2008 with approximately 35 employees. The firm specialises in greenhouse gas (GHG) and air quality emissions calculation and review, serving national governments, international organisations, cities and local authorities, and construction and property developers. Its core service lines include inventories and projections, monitoring reporting and verification (MRV) systems, policies and wider impacts analysis, corporate climate change advisory, sustainable buildings and energy, waste and circular economy, rail modelling and data analysis, and data visualisation.
The firm's technology stack combines bespoke proprietary tools with established modelling platforms. Key proprietary assets include the MRV Portal (a configurable cloud platform for national GHG inventory compilation and reporting, deployed in Tanzania, Liberia, and Iceland), SEEsim (the first UK rail energy and emissions simulator for the GB freight network, calibrated against OTMR data), the Carbon Scenario Model (Excel-based local authority emissions modelling to 2030), the QA Analyst Tool for inventory QA/QC, and the Climate Action Database and Reporting Portal for policies and measures tracking. For air quality assessments, Aether uses third-party dispersion modelling tools such as ADMS-Roads and AERMOD.
Aether operates a professional services, project-based revenue model under long-term framework contracts and direct tenders with government and inter-governmental clients (DEFRA, EEA, European Commission, Irish EPA, States of Jersey, UAE MOCCAE, and others), supplemented by UNDP/GEF-funded capacity building programmes in non-Annex I countries and air quality advisory work for property developers. The go-to-market is enterprise field sales driven by thought leadership (case studies, publications, conference participation), direct client relationships with government procurement, and referrals from multilateral organisations. Pricing is negotiated bilaterally on a project basis and is not publicly disclosed.
