Cutting carbon dioxide emissions in the UK

The average household could save around 1.5 tonnes of carbon dioxide (CO₂) a year by making their home energy efficient.

If everyone with gas central heating installed a new condensing boiler, we'd cut emissions by 12.5 million tonnes. We'd also save around £1.9 billion per year on our energy bills and enough energy to heat over 3.3 million homes for a year.

If everyone installed cavity wall insulation, we'd cut CO₂ emissions by 4.6 million tonnes, enough to fill 1 million hot air balloons.

If every home that could had 270mm loft insulation we'd save 3.8 million tonnes of CO₂, the same as the annual emissions of around 650,000 homes.

If everyone put an insulation jacket on their hot water tank, we'd cut CO₂ emissions by 900,000 tonnes - enough to fill around 182,000 hot air balloons.

If everyone in the UK installed just one energy saving light bulb, we'd save enough CO₂ to fill the Albert Hall over 1,900 times.
