A net zero carbon budget for the whole transport sector

SummaryIntroductionThe Growing Gap Between Transport Carbon Emissions and TargetsDifferent Treatment For Aviation and ShippingThe Scale of The Challenge to 2030ConclusionsAcknowledgementsThe Department for Transport (DfT) has gone rogue on climate change. Transport is the only sector where greenhouse gas emissions have increased since 1990. A new analysis shows that the DfTcontinued failure to curb emissions will lead to the UK breaching existing carbon budgets over the next decade, even before budgets are tightened on the pathway to net zero. Radical action to cut emissions from road transport and aviation over the next decade and beyond are needed. This will require DfT to constrain demand for road and air travel.Get price
