Natural gas not a ‘bridge fuel’ to cleaner trucks and cars – study

Natural gas is not a ‘bridge fuel’ to a cleaner future for cars and trucks – as the fossil fuel industry claims – because it would be largely ineffective in cutting greenhouse gas (GHG) emissions and air pollution, an independent study has found. Instead petrol-hybrid, electric and hydrogen cars deliver much greater climate benefits.

Lifetime costs

The Commission’s long-awaited draft legislation on the rules for public authorities to buy road vehicles came out in December, and as expected they will require all authorities in the EU to consider the lifetime cost of pollution emissions and fuel consumption. The principle of bodies such as public transport authorities paying more for vehicles that are environmentally better than cheaper options has been accepted for some time, but the new legislation proposes a harmonised EU methodology for calculating the lifecycle costs of fuel, carbon dioxide, nitrogen oxides, hydrocarbons and particulate matter. One study predicts the proposed law could save up to 1.9 million tonnes of CO2 a year by 2017.
