Energy Saving Trust (EST) 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.
Energy Saving Trust is an independent, not-for-profit organization funded by the government and the private sector. It is a social enterprise, and also has a charitable foundation. The EST has regional offices in England, and country offices in Wales, Northern Ireland, and Scotland. It maintains a comprehensive website, and a network of numerous local advice centres.
The Energy Saving Trust was formally established in November 1992. 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, and to the global June 1992 Earth Summit call to reduce greenhouse gas emissions and prevent global warming and climate change. In the wake of energy-supplier privatisation in the UK, the EST was also specifically formed as an instrument to ensure energy conservation and carbon-emission reduction in a free-market environment. The structure, scope, nature, and funding of EST'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. It is the largest provider of energy-saving advice, and has effected significant and measurable savings of energy, money, and carbon.
EST'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. The EST's target audience is consumers, local authorities, energy companies, and policy makers. Among other activities, they provide:
