Two years after the Dieselgate scandal exposed the dirty nature of diesel cars, a new study (LINK TO STUDY) by Transport & Environment (T&E) shows that diesel cars not only pollute the air but also emit more climate-change emissions (CO2) than petrol cars. A lifecycle analysis of vehicle emissions proves that diesel cars over its lifetime emit 3.65 tonnes of CO2 more than a petrol equivalent. Diesel’s higher climate impact is due to a more energy-intensive refining of the diesel fuel; more materials required in the production of heavier and more complex engines; higher emissions from the biodiesel blended in the diesel fuel; and longer mileage because fuel is cheaper - see infographics below.
Transport & Environment (T&E) welcomes European Commission’s proposal today on smart road tolls and its commitment to zero-emission mobility. The Commission also reaffirmed its commitment to set stricter CO2 standards for cars, vans and, for the first time, trucks. These are moves in the right direction, but the real test of the EU’s intentions will be the ambition of the CO2 standards and whether it proposes a zero-emission vehicle mandate, the sustainable transport group said.
The overall direction for road transport in today’s leaked draft of the European Commission strategy for low-emission mobility has been welcomed by Transport & Environment (T&E), though the sustainable transport group has urged stronger action on greenhouse gases from international aviation and shipping.
Increasing the use of natural gas in cars and trucks would be largely ineffective in reducing greenhouse gas (GHG) emissions and air pollution, a new independent study finds. There are no GHG savings in shifting from diesel cars and trucks to compressed or liquefied natural gas (LNG) cars and trucks, while petrol-hybrid, electric and hydrogen cars deliver much greater climate benefits, the study for sustainable transport group Transport & Environment says.
Europeans pay 14 cent more on average in tax for a litre of petrol than for diesel – indirectly subsidising diesel cars to the order of €2,600 per vehicle, a new study by sustainable transport group Transport & Environment (T&E) finds. This 30% tax gap in favour of diesel is a key reason for diesel cars’ majority share of new sales in Europe and leads to air quality problems where nine out of 10 diesel cars fail to meet NOx limits when driven on the road. 
Europe can only meet the climate targets Heads of State agreed on for sectors outside the Emissions Trading System (ETS) if it sets fuel efficiency standards for new cars, vans and lorries by 2025 or earlier, a new study by Transport & Environment (T&E) reveals . In a middle-of-the-road scenario where transport would cut CO2 emissions by 30% by 2030 , the study found that CO2 standards for all vehicles (cars, vans and lorries) in 2025 and 2030 would deliver a whopping 42% of the emissions reduction required from transport.
Green Car Tax rating highlights EU countries with the most and least supportive tax arrangements to encourage low-carbon, fuel efficient cars. Initial registration taxes (purchase taxes) and company car taxes that are steeply differentiated by CO₂ boost the purchase of lower-emissions cars in the Netherlands, Denmark and France.
Even if carbon prices in Europe’s emissions trading system (ETS) trebled from today’s levels , including road transport in the ETS would only reduce oil use and CO2 emissions from transport by 3% over the next 15 years, a new study by Cambridge Econometrics reveals. This level is insufficient for road transport to make a proportionate contribution to Europe’s climate and energy security goals.
Transport & Environment's reaction to the Parliament hearing for Commissioner-designate for Climate Action and Energy, Miguel Arias Cañete.
Despite three-hours of grilling by MEPs of the Commissioner-designate for Climate Action and Energy, Miguel Arias Cañete failed to explain how there is no conflict of interest with his brother-in-law Miguel Domecq Solís being a director of two oil companies.
Brussels - Fuel tax havens such as Luxembourg and Spain may have to raise their low diesel taxes following a vote in the European Parliament in Strasbourg this afternoon on a proposal to revise the EU’s Energy Tax law. Commenting on the outcome of the vote, Magnus Nilsson, senior campaigner at T&E said: “This vote is good news for countries like Portugal, Belgium, France and Germany who currently lose billions in tax revenue as a result of lorries filling up in fuel tax havens such as Luxembourg and Spain. Lower diesel taxes are bad for the climate and force governments to find cash elsewhere, such as by raising job-killing labour taxes. ”
