<p>Homes – both new and existing – account for 20 per cent of emissions, and this Department recognises the important contribution that the energy efficiency of homes has to make in meeting the Government’s 2050 target.</p><p>As part of this, we have consulted on introducing a Future Homes Standard by 2025. This means new homes will be fit for the future, with low carbon heating and lower energy use through high levels of energy efficiency. As a stepping stone to the Future Homes Standard we are proposing a meaningful but achievable strengthening in these requirements in 2020 and then a further strengthening by 2025.</p>
