There is a clear and important role for renewable heat in meeting our carbon targets. The Clean Growth Strategy sets out in detail how we will achieve this, with a move to more renewable sources of heat over the coming decades. In the meantime, raising standards for boilers presents an opportunity to improve energy efficiency in millions of homes, saving carbon emissions now, while giving householders greater comfort. These changes will also help lay the groundwork for even greater change in the future, by supporting low temperature systems.
