Good for the planet. Good for your pocket.
Less carbon. More life. A mission we all share.
The Carbon Mission is an open project to stop global warming. Everyone can join in to save our planet, and save money while doing it.
Three ways we help you save
To give everyone practical ways to reduce their carbon emissions and their bills, through interactive guides, advice on cutting the power their devices use, and buying guides.
Interactive guides
Friendly step-by-step guides you can click through at your own pace. Pick a room or a habit, follow along, and tick off each win as you go.
Cut your device power
TVs, consoles, chargers and computers keep sipping electricity. Learn the simple switches that trim what they use, and try the calculator to see your saving.
Buying guides
Need a new fridge, washing machine, dishwasher or TV? Compare real models and see which costs less to run and is kinder to the planet for years to come.
On the way
See what one switch-off saves
Pick any device at home, such as a TV, a games console or a heater. Tell us how much power it uses and how long you could switch it off for each day. We will show the money and the carbon you save in a year, side by side.
Your saving, every year
- Money saved
- £19.21
- a year off your bill
- Carbon saved
- 10.5 kg
- a year kept out of the air
Nice one! That is 73 kWh of electricity you no longer pay for. Every switch-off counts.
How we worked it out
Watts × hours a day × 365 days ÷ 1,000 gives the kWh (kilowatt-hours, the units on your bill) saved in a year. We multiply that by the price of one kWh for the money, and by the carbon released per kWh for the carbon.
- Price: Ofgem, energy price cap for 1 October to 31 December 2026: 26.32p per kWh (paying by Direct Debit, average for England, Scotland and Wales).
- Carbon: Department for Energy Security and Net Zero, greenhouse gas conversion factors 2026: 0.144 kg per kWh (0.131 for generating UK electricity plus 0.013 lost on the way to your home), counting carbon dioxide and the other greenhouse gases together.
These are averages, so your own saving may be a little different. Your bill shows the exact price you pay.
