Here are the top five:

  • 1. Climate Change Act

The UK became the first country in the world to introduce a legally binding framework to cut greenhouse gas emissions. Its target of reducing emissions by 80% on 1990 levels by 2050 will be met through carbon budgets, the first of which will be set out in June 2009.

  • 2. Energy and Planning Acts

Working together, the two bills will make it easier for industry to invest in new energy infrastructure projects.
