Merton Council declared a climate emergency in July 2019 and set carbon reduction targets to decarbonise the Council by 2030 and the borough of Merton by 2050. Merton has a history of taking strong action in this area and has had a climate strategy since 2009. However, unprecedented change will be necessary going forward. Merton Council contracted Aether, along with SE2, to provide support in the preparation of Merton’s climate action plan. The challenge was to identify and quantify a range of actions that Merton might undertake to achieve the decarbonisation targets.
To underpin the development of Merton’s Climate Strategy & Action Plan, Aether supported Merton Council by:
We partnered with SE2 to deliver two workshops; a small initial session with council staff focusing on the scope and principles of the targets, and a larger workshop with local stakeholders and interest groups to discuss the key actions that should be included in the decarbonisation modelling scenario.
Our modelling used the Carbon Scenario Model (CSM), an Excel based tool to develop decarbonisation pathways for the council up to 2030 and the borough to 2050, including individual GHG savings and costs of actions.
Merton Council now has a greater understanding of the actions that are required within Merton to meet their decarbonisation targets. The actions identified and cost estimates have been used in the preparation of the new Climate Strategy & Action Plan.

Aether developed an online, interactive data visualisation for the City of London that could be used by policy makers and the general public to explore data and information on air quality. Topics covered include air pollutant emissions, bus fleet emission control technologies and the health impacts of air pollution.

This RSSB project undertook research into the extent to which diesel trains are idling, where this occurs, the reasons for it, and the implications for air quality. The findings were used to produce guidance to help the rail industry to reduce the amount of idling without compromising the operation of the railway. Aether led the project team, with specialist advice from Carrickarory Consulting and Atkins-Realis.
