We'll use this to split shared energy costs fairly between everyone in your home.
Your home energy use is typically one of your biggest sources of emissions.
If you don't pay bills separately (e.g. renting), £50–80/month is typical for a 2-bed household.
For gas, the typical UK household spends £60–120/month. Heat pump users often see lower annual bills.
If you have your energy bills to hand, enter your actual kWh figures for a more accurate result. We automatically adjust for seasonal variation based on the current month, so a summer reading won't be over-extrapolated to the full year. Otherwise, click "Use UK averages" to skip.
UK average: ~250–350 kWh/month for a 2–3 bed home.
UK average: ~400–900 kWh gas/month depending on season.
Your own personal miles driven — not your household's total.
What you eat is one of the largest and most changeable parts of your footprint.
Include your share of the household grocery shop + any drinks, snacks and online food orders. UK average is around £35–45/person/week.
e.g. strawberries in January, asparagus in autumn, exotic tropical fruits year-round
A takeaway latte carries roughly 0.3 kg CO₂e. Home-made filter coffee is about 0.15 kg CO₂e per cup.
Flights are often the single biggest lever in a personal carbon footprint. We include the full radiative forcing effect (as recommended by DEFRA).
The "stuff" we buy and how we use technology both have a surprisingly significant footprint.
Each parcel delivery generates roughly 0.5 kg CO₂e on average.
Each AI query uses roughly 0.002–0.01 kg CO₂e — small individually, but the sector's growth is significant.
The money sitting in your bank and pension is being invested — often in fossil fuels. These "financed emissions" are reported separately from your day-to-day footprint.
Rankings based on fossil fuel financing data from Banking on Climate Chaos 2024 & Make My Money Matter research.
Your savings amplify financed emissions — a larger pot means more money being lent to businesses (including fossil fuel companies).

These are the emissions from investments your money is passively funding. Switching to a green bank or sustainable pension fund can have a huge impact — sustainable funds can perform just as well or even outperform standard funds, but please consult your pension provider.
Based on your results, these are the highest-impact actions you can take — ranked by the carbon and money savings available to you.
