London’s low-carbon economy is estimated at over £30bn. The capital has the UK’s greatest concentration of green businesses, but there is still significant potential for growth. EIT Climate-KIC is working with the Greater London Authority (GLA) to establish CleanTech London to bring together existing projects and identify new areas and initiatives to accelerate innovation and position London as a world-leading CleanTech innovation hub.


CleanTech London has three overarching aims:

  • Build a cohesive CleanTech community with a unified voice that represents London nationally and globally
  • Stimulate innovation and enhance market access by supporting CleanTech businesses to address London’s environmental and economic challenges
  • Remove barriers to scaling-up CleanTech innovations


CleanTech London is creating a comprehensive stakeholder map of the CleanTech sector, which will inform a framework to strategically support the sector. It will build on and bring together existing activities – including the Climate-KIC Accelerator; Sustainable Ventures Accelerator and the LWARB Circular London Accelerator for the built environment – to provide more strategic support to CleanTech innovators.

It has also established the CleanTech Test Bed, with support from Climate-KIC, which will work with local authorities to inform their procurement mechanisms for news innovations, developing new testing approaches that will stimulate demand for CleanTech innovation.

CleanTech London’s cross sector initiatives are designed to ensure London’s CleanTech businesses grow sustainably, contribute to addressing London’s environmental challenges, create jobs, and improve productivity.

Featured Projects in London

Transforming cities one district at a time

The Queen Elizabeth Olympic Park (QEOP) redevelopment plan is creating a dynamic new district with new jobs, housing and a cultural district. In doing so, it wanted to optimise energy efficiency and resources, and uses data to enhance quality of life. Climate-KIC helped form partnerships to develop new energy optimisation systems, energy conservation programmes, and data collection and management platforms, leading to significant energy savings.

Test beds for a low carbon future

A pilot project to help local authorities test, co-design and procure innovations is helping start-ups develop innovation that more directly meets the needs of local government, whilst supporting local authorities to procure locally developed solutions that help them meet energy objectives.
