Energy Saving Trust is a British organization devoted to promoting energy efficiency, energy conservation, and the sustainable use of energy, thereby reducing carbon dioxide emissions and helping to prevent man-made climate change. It was founded in the United Kingdom as a government-sponsored initiative in 1992, following the global Earth Summit.^[1]

Energy Saving Trust is a private company limited by guarantee. All profits are invested back into the business in pursuit of its mission to address the climate emergency. ^{[2][3] [4]} Energy Saving Trust has regional offices in England, Wales, Northern Ireland, and Scotland and runs numerous energy advice services in the UK.^[1][5] It maintains a comprehensive website, and customer advice service.^[6]

Energy Saving Trust was formally established in November 1992.^[7][3] It was formed, as a public-private partnership, in response both to the director-general of Ofgas's 1991 proposal to increase energy efficiency in natural gas use,^[8][9][10] and to the global June 1992 Earth Summit call to reduce greenhouse gas emissions and prevent global warming and climate change.^[1][11] In the wake of energy-supplier privatisation in the UK, Energy Saving Trust was also specifically formed as an instrument to ensure energy conservation and carbon-emission reduction in a free-market environment.^[12][10] The structure, scope, nature, and funding of Energy Saving Trust's activities and programmes have varied over the years due to governmental policy changes; however its primary focus – on consumers and households – has remained the same.^[11][13] It is the largest provider of energy-saving advice, and has affected significant and measurable savings of energy, money, and carbon.^[11]

Energy Saving Trust's main goals are to achieve the sustainable use of energy and to cut carbon dioxide emissions. It acts as a bridge between consumers, government, trade, businesses, third sector organisations, local authorities, and the energy market.^[2][4] Energy Saving Trust's target audience is consumers, local authorities, energy companies, and policy makers.^[14] Among other activities, they provide:
