Transport sector policies already contribute to moderating greenhouse gas emissions from road vehicles. They are increasingly designed to contribute to overall societal targets to mitigate climate change. While abatement costs in transport are relatively high, there are plausible arguments in...

Methane is a major anthropogenic greenhouse gas, second only to carbon dioxide (CO2) in its impact on climate change. Methane (CH4) has a high global warming potential that is 25 times as large as the one of CO2 on a 100 year time horizon according to the latest IPCC report. Thus, CH4...
