The UK Government's Energy White Paper from 2007 addresses concerns about energy security and climate change. It predicts a rise in CO2 emissions from transport until 2015, followed by a decrease due to better vehicle fuel efficiency. The goal is to reduce transport's carbon footprint by 2-5.5MtC per year by 2020. Strategies include carbon pricing, technology improvements (like hybrid and electric vehicles), and changing behaviors. The UK is pushing for road transport to be included in the Emissions Trading Scheme to raise fuel prices and reduce emissions. The use of biofuels and renewable energy sources is encouraged to help achieve these goals.
