The royal society - January 2008

Our climate is changing and there is now scientific, social and political recognition that this is very likely a consequence of increasing anthropogenic greenhouse gas (GHG) emissions. Transport now accounts for about 20% of global anthropogenic carbon dioxide emissions and 25% of emissions in the United Kingdom (UK), and these figures are growing faster than for any other sector.

If the UK is to reach its target of reducing emissions by 60% by 2050 then cuts will need to be made in the transport sector.

 

However, access to energy underpins our current way of life and the hopes of peoples around the world for improved lives. Mobility is a core component of these aspirations. Transport has become the main driver for increasing global primary oil demand, which is predicted to grow by 1.3% per year up to 2030, reaching 116 million barrelsa per day (up from 84 million barrels per day in 2005).

The transport sector in particular relies almost entirely on oil, which is predicted to become increasingly scarce and costly in the next few decades and supplies of which are vulnerable to interruption.
