As T&E's briefings (downloadable below) explain, the study concludes that the increased use of natural gas in road transport is largely ineffective in reducing greenhouse gases or air pollution. The immediate benefits are small or non-existent; while the environmental costs, societal costs and costs to operators are negative for almost all vehicle categories.
While the study also finds clear air pollution advantages from using LNG in the shipping sector, its GHG emissions benefits are highly dependent on methane slip at the production, distribution and operational levels. LNG ships also incur higher infrastructure and capital costs.
Natural gas is not a ‘bridge fuel’, as claimed, but an expensive dead-end on the pathway to decarbonising transport.
