How to Reduce Carbon Footprint of Gas Central Heating in the Uk

The world needs to leave most of its coal, oil and gas in the ground between now and 20 50 if we're to stand any chance of keeping climate change within a one point five degree celsius level. But 77 % of respondents said that they do use gas central heating. So how do we cut our carbon footprint while not leaving three quarters of the country out in the cold? One answer might be to send something different down the pipe lines, hydrogen. When this burns, it releases only water as a waste product.
