Emissions from transport affect the climate both in the short and long term. New research explored the size and mix of emissions with short and long-lived effects and found that road transport has the largest effect on global mean temperature. The study conducted under the EU-funded QUANTIFY project compared the effects of current emissions from road, air, rail and shipping. The study explored the effects of emissions from a single year over different time periods and found that emissions from road transport have the most impact in the long term (20-100 years).
