1. A bold ambition
The Mayor has set out an ambition for the capital to be zero carbon by 2050, alongside a transport strategy to achieve 80% of journeys to be walking, cycling or public transport by 2041, paving the way for a city with the best air quality of any major city in the world.
2. Access to capital
At the epicentre of the world’s financial and insurance markets, London is a global leader in green finance. Green bonds listed on the London Stock Exchange have raised more than £25.3bn in seven different currencies.
London is also the second biggest source of capital for cleantech in the world after Silicon Valley, with VC investment that outstrips the rest of Europe.
3. A place where talent thrives
London is where world-leading expertise in technology, engineering, energy, finance, legal and environmental research all converge. Two of the world’s top 50 universities for engineering and technology are in London – UCL and Imperial College London, and the city boasts more software developers than many large European countries.
London is a global hotspot for cleantech innovation – innovation that addresses the causes and effects of man-made climate change.Professor Richard Templer

4. Innovative infrastructure
The city’s electric vehicle charging network is one of the biggest of any urban area and London mandates vehicle-charging infrastructure in new developments.
To improve air quality, London also implemented the Ultra Low Emission Zone (ULEZ), requiring most vehicles to meet new, tighter exhaust emission standards or pay a daily charge to travel within the ULEZ area.
London’s ecosystem consists of a wide scope of businesses, public bodies and regulators, as well as a kaleidoscope of initiatives and spaces for entrepreneurs. From Advance London to Better Futures and from Sustainable Ventures to the Centre for Cleantech Innovation, London-based startups have access to the network and support to grow and thrive.
