To understand how much CO₂ can be saved by active mobility in cities, Academy WebTV travelled to Oxford and London to meet with Dr Christian Brand - Senior Research Fellow and Associate Professor at the ECI and TSU - and Dr Audrey de Nazelle - Senior Lecturer and Co-Deputy Director of the Centre of Environmental Policy at the Imperial College London.

People in cities often choose how to travel based on how long it will take. We wanted to see what would happen if everyone acted selfishly. How would that compare, we wondered, with a theoretical case in which people chose their mode to minimise travel times for society as a whole and not only for themselves. Dr Juan Pablo Orjuela explores what happens in an article for The Conversation.

Last year, the British government announced the sale of new petrol and diesel cars and vans would be banned by 2030. To achieve this, the UK needs to rapidly stimulate uptake of electric vehicles to meet the end-of-decade goal. Prof Tim Schwanen spoke to ABC NewsRadio's Thomas Oriti on ABC NewsRadio's national breakfast radio programme.

Transport accounts for 21% of global carbon emissions. It is now the largest emitting sector in many developed countries. On 'transport day' at the COP26 climate summit, Dr Christian Brand provides seven reasons why global transport is particularly hard to decarbonise. Part of The Conversation's coverage on COP26.

Researcher at the Oxford Martin Programme on Informal Cities, Jin-ho Chung, tells us the research trends of climate mobilities that show the growing significance of the urban lens through which climate migration is understood. It demonstrates why it is important to consider the dynamics of the urban systems that would be affected by both climate-related migration, and the direct impacts of climate change.

Green groups fear the policy will embed car use at the expense of healthier and ultimately cheaper alternatives. Article in The Guardian includes expert comment by Prof Tim Schwanen, director of the Transport Studies Unit.

The move to electric vehicles is not a silver bullet, according to Professor Tim Schwanen, director of Oxford's Transport Studies Unit.
