Transport greenhouse gas emissions: Range of measures needed
- People seem to have a fixed part of their time and budget that they use for transport. This means that transport tends to increase with improved infrastructure and as people get richer, said EEA Executive Director Professor Jacqueline McGlade in a speech to the Austrian parliament on 3 October at an event to celebrate Austria's 10th anniversary as an EU member.
She pointed out that achieving reduction in greenhouse gas emissions in the transport sector was difficult, as there are no lower carbon fuels to switch to on a large scale today. Biofuels could cover but a small percentage. While hydrogen from renewable resources could play a role in the medium to long term, we can to some extent rely on technologies such as hybrid vehicles in the shorter term. Although technology can take us part of the way to a more sustainable mobility future, it will not solve all problems.
