Individual footprint: 2.6 tonnes

Measured using the Act On CO2 carbon calculator.

Measures taken in the last 12 months to reduce footprint
“I've managed to reduce our household's footprint in the last 12 months by 26% by 1) replacing our 10-yr old petrol Rover car with a nearly new diesel Skoda Fabia car that emits only 120 g CO2/km 2) replacing old and smeary double glazing on the first floor with Band A double glazing (this also cuts out drafts) and 3) making Ecotricity our supplier of electricity (thereby halving our emisisons per kWh).”

Measures to be taken in the next 12 months to reduce footprint
“This heating season I've tried to control the gas CH boiler semi-manually to keep the temperature at the thermostat in the range 16-18 degC. This avoids the boiler cycling wastefully around 18degC. When the temp. drops to around 16 I just put the boiler on again. It seems to save gas. Maybe we just need a new thermostat! We certainly ought to move to a modern condensing boiler (gas is the single biggest component of our footprint) and are waiting for the old one to 'die'. Maybe in 2010? Might also go for a new double-glazed front door without holes (no letterbox and keyhole) in it which should save heat loss.”

Any other comments
“My real DIY calculated footprint is actually 2.8 tonnes but ActonCO2's figure is pretty close to that.”
