Cars emit less CO2 per passenger km than buses

UK government emissions data shows that buses outside of London emit an average of 221g/km CO2e (CO2 equivalent) per passenger km compared to a small petrol car (201g/km), a small diesel car (172g/km) and a medium diesel car (215g/km). A car containing two people would obviously halve these figures. London buses, because of their higher average occupancy, fare better at 102g/km.

UK government emissions data shows that buses outside of London emit an average of 221g/km CO2e (CO2 equivalent) per passenger km compared to a small petrol car (201g/km), a small diesel car (172g/km) and a medium diesel car (215g/km).  A car containing two people would obviously halve these figures. London buses, because of their higher average occupancy, fare better at 102g/km.

"Perhaps those who criticise lone car drivers should turn their attention to empty off-peak buses instead,” says Paul Biggs, environment spokesman at the Association of British Drivers. “Although buses provide an important public service, even London can only manage an average occupancy of around 15 passengers. Modern efficient cars outperform buses not just for CO2 emissions, but for genuine pollutants as well," Biggs adds.

    The latest data available suggests that traffic pollution is still harmful to health in many parts of Europe. Transport in Europe is responsible for damaging levels of air pollutants and a quarter of EU greenhouse gas emissions. Many of the resulting environmental problems can be addressed by stepping up efforts to meet new EU targets, according to the latest report from the European Environment Agency (EEA). The EEA’s annual report under the Transport and Environment Reporting Mechanism (TERM) assesses the

    More collaboration is needed to reduce the impact of highways on the environment, particularly air quality. The technology already exists, argue Bram Miller* and Martin Broderick* The European Environment Agency produced a report showing that a slow improvement in air quality has been observed across Europe. However, 9% of urban Europeans were exposed to nitrogen dioxide emissions in excess of the EU’s annual maximum limit in 2015. Meanwhile, associations between highways and the environment tend to be n

Geoff Hadwick reports from the ERF in Brussels The familiar physical asset called the road will increasingly be seen as part of an emerging global services sector. Given that, the role of the road is changing, notes Christophe Nicodème, general director of the European Union Road Federation (ERF). We need to think much more carefully about planning highway infrastructure in terms of people’s needs, said Nicodème,
