London Sustainability Exchange (LSx) aimed to accelerate the transition to a sustainable London by connecting and motivating people. As a charity we worked in partnership with business, government and the voluntary sector to: Reduce London's environmental footprint Improve the lives of London's disadvantaged communities Improve the health of Londoners Improve the knowledge and skills of our communities to achieve these goals To achieve these goals we ran learning networks and innovative exemplar schemes. We also sought to influence policy and practice throughout London. We were founded in 2001 by the City of London and a group of influential partners, who continue to shape our development.
