The Mayor of London’s Zero Carbon Accelerator helps London-based public sector organisations and social housing buildings to accelerate the decarbonisation of their buildings and estates. The programme provides targeted support and expertise, supporting organisations’ journey to London’s net zero target by 2030.

The Mayor of London is delivering the Zero Carbon Accelerator in collaboration with Mott MacDonald, Energy Saving Trust and an alliance of experts: ACA Studios, Altair, Ambue, Arthian, ClimateView, COWI, EEVS, Energiesprong UK, Energy Projects Management Limited, ERM, IES, Pascall+Watson Architects, Pollard Thomas Edwards, Retrofit Academy, Woodward Energy Consulting and Zerogram.

The programme launched in June 2024 and runs until autumn 2028.

What is our role?

We lead the communications and engagement side of the programme, engaging with all kinds of stakeholders, decarbonisation experts in the Alliance, organisations and networks. 

Who can the Zero Carbon Accelerator support?

The Zero Carbon Accelerator supports London-based organisations including:

  • local authorities
  • the Greater London Authority Group
  • health providers
  • education providers
  • social housing providers
  • cultural and heritage institutions
  • community groups

The Zero Carbon Accelerator is focused on supporting decarbonisation projects from public sector organisations across three strategic areas, which are aligned with Mayoral priorities:

  • domestic decarbonisation, making people’s homes in London more energy efficient, affordable to heat and better for their health.
  • RE:FIT 5, the Mayor’s refreshed energy performance and retrofit framework.
  • strategic decarbonisation projects at scale that take an area-based approach, including Great British Energy-funded NHS Trust projects and community energy initiatives delivered through the government’s Local Power Plan.
