According to a report published today by the Royal Academy of Engineering, the UK has no hope of reaching its binding 2050 target for CO2 reductions without a serious shake-up of the way homes are heated. The publication, Heat: degrees of comfort, finds that even with the most modern gas boilers and state-of-the art insulation, we cannot continue to heat so many homes by natural gas and still achieve an 80 percent cut in emissions as laid down in the Climate Change Act 2008.
