Heating and insulation
Loft insulation (of more than 250mm thick)
Cold appliance insulation (by inserting vacuum-insulated panels)
saving: 75% of the heat loss of your hot water tank. Source
Reduce the heating by just 1°C
Switch to a condensing boiler
Replace regular light bulbs with energy saving equivalents
Follow the green flower
Buy 'Energy Saving' appliances and look for the European Ecolabel. This signifies that it has been judged as among the best in its class.
saving: 200kg CO2 per year. Source
Reduce to a 30°C wash
When using the kettle only boil the water you need
saving: 20kg CO2 per year. Source
Switch off when not in use. NB: Standby is NOT off
e.g. Mobile phone chargers
saving: £60 million electricity and 250,000 tonnes of CO2 per year (UK-wide). Source
e.g. Turning off televisions at night
saving: enough energy to power a 150,000 person town. Source
Slow down from 70mph to 50mph
saving: 25 per cent CO 2 emissions. Source
Reduce car journeys under 5 miles by a third
saving: 1.5 million tonnes CO2 which accounts for 0.3% of our total UK carbon emissions. Source
Use more public transport
On average traveling by bus is almost twice as efficient than traveling by car. Traveling by rail is about five times as efficient. See Carbon Footprint - Transport for more details.
Flying contributes about four times more emissions than traveling by train (see Carbon Footprint - Transport ). When you are traveling thousands of miles this makes a dramatic difference.
Next time you buy a car, aim for one that emits less than 120 grammes of CO2 per litre. Avoid sports cars, 4x4s, SUVs and people carriers.
The bonus for you - the greener the car, the cheaper the tax. Source
If everyone took energy efficiency seriously, the average householder could reduce their CO2 emissions by 2 tonnes every year and their energy bills by £300. Source
However, we must remember that energy efficiency alone cannot reduce emissions by the amounts needed. We must also aim for an absolute reduction in emissions.
