Energy efficiency in British housing - Wikipedia emissions. Although carbon emissions from housing have remained fairly stable since 1990 (due to the increase in household energy use having been compensated for by the 'dash for gas'), housing accounted for around 30% of all the UK's carbon dioxide emissions in 2004 (40 million tonnes of carbon) up from 26.42% in 1990 as a proportion of the UK's total emissions.
