Case studies

LULUCF GHG Inventory Support for Romania

Aether is supporting the Romanian National Research and Development Institute for Cryogenic and Isotopic Technologies (ICSI) in the compilation of its national greenhouse gas (GHG) emissions inventory for non-forest land areas. We are helping to ensure that Romania’s land use, land use change and forestry (LULUCF) inventory is robust and of high quality.

Driving emission reductions through the public sector supply chain: Scope 3 emissions

Aether contributed to the analysis of procurement (Scope 3) emissions reporting in the Scottish public sector. The research aimed to demonstrate approaches and tools available to Scottish public bodies. The aim was to understand and report their supply chain emissions, providing options for action to improve supply chain reporting across the public sector.

Runnymede Borough Council Climate Change Study

Aether, in partnership with Land Use Consultants (LUC), delivered a package of works to support Runnymede Borough Council’s (RBC) review of the 2030 Local Plan with a view to introducing stronger policies to address the impacts of climate change.

Ealing Council Climate Action Plan Multi-Criteria Analysis

Aether developed a multi-criteria analysis of Ealing Council’s Climate and Ecological Emergency Strategy (CEES) to support the Council with prioritisation and delivery of climate actions to reach their 2030 target of carbon neutrality.

Luton Council Net Zero Roadmap and Climate Policy and Action Plan

Aether, alongside SE2 and associate Joanne Wade, developed a Net Zero Roadmap and Climate Policy and Action Plan to support the council in its vision of a net zero town by 2040.
