A litre of LPG causes 1.5kg CO2e, diesel causes 2.6kg CO2e, petrol causes 2.2-2.3kg CO2e

LPG is no longer the obvious choice due to the efficiency of diesel and petrol engines.

Diesel cars tend to do more miles per gallon than petrol so the CO2e emissions per mile are lower. However, health concerns related to particulates from diesel engines suggest that diesel is no longer a favourable option despite its lower climate impact. 

Biodiesels raise similar health concerns. 

Biofuels have not been proven to be beneficial and the increased demand for land puts pressure on food prices and is responsible for further destruction of rainforest. 

The production of ethanol from maize consumes substantially more energy than it produces.

Petrol has lower health impacts than diesel but higher CO2e emissions. 

Hybrid petrol vehicles provide greatly improved fuel efficiency without the health impacts of diesel. 

Electric vehicles' emissions depend on the fuel used to generate the electricity. While their reduced pollution is beneficial especially in urban areas, electric vehicles have variable climate change impact.

We need business to innovate us out of a dependence on fossil fuels for private personal transport. In the meantime we can still choose the least harmful fuels possible.

    Over the last couple of years, have swapped from petrol vehicles to a Golf diesel (long trips) and Nissan LEAF electric vehicle for trips around the city.  The EV is our preferred mode of transport as it is powered by electricity produced from a wind farm.
