They represent 20% of
emissions we can control
Per UK citizen – cars
contribute 1.2 tonnes a year
Per car – each car contributes 2.6 tonnes a
year

… but emissions are unequally distributed
Highest 10% of
emitters are
responsible for 43%
of emissions
Lowest 10% of emitters are responsible for 1% of emissions

Just you (g CO2)
2 of you(g CO2)
Taking a black cab (assuming 233 g/km) 1400 700
Using your car (assuming old vehicle at 160g/km)
960 480
Using a new Prius hybrid (assuming new car at 99 g/km)
594 298
Take the bus (assuming 1300g/km, 20 passengers)

Main options for reducing emissions from car travel (Based on annual emission per car of 2.6 tonnes
travelling 9,000 miles per year)Option Main impact on typical CO2 emissions
Car clubs 1.8 tonnes
Drive less Reduce by 2000 miles – 0.57 tonnes
Drive efficiently 0.9 tonnes
New efficient car Would only reduce emissions if old car at end of life
LPG car 0.35 tonnes
Hybrid car 1.1 tonnes
Smaller car A small diesel with manual transmission halves emissions
Automatic vs manual 0.3 tonnes
Small manual diesel 0.9 tonnes
Electric car 1.3 tonnes
Biofuels No convincing evidence of savings unless you use used chip fat
