Plain-English why
Copyable takeaway
What this means
Equivalent to 25,000 km by car, 21.4 short-haul return flights, or 203 trees.
Formula used
Bill/price to kWh; kWh times fuel emission factor; compare with bedroom-adjusted average.
Worked example
Gas bill £1,400, 3-bed UK => 4.3 tonnes CO2e, 78% above average, 21.4 flights.
Common questions
Can I use this internationally?
Yes. Currency selectors are display-only unless a tool explicitly says otherwise; no currency conversion is performed.
How exact is the result?
It follows the published Technofatty formula for this tool, but real life can add fees, rules, timing quirks, and context.
Plain-English summary
Heating footprint: 4.3 tonnes CO2e, 78% above average.
This section translates the result into a short, direct takeaway rather than leaving the page at a bare number.
