The reduction in the cost of green energy and the growing demand for these alternative sources has led the Office for Budget Responsibility to forecast that £8.4 billion will be spent on renewable projects in the UK in 2020/21. Britain’s Climate Change Act of 2008 introduced the world’s first long-term national framework to tackle climate change, setting a legally binding target of an 80% reduction in GHG emissions by 2050, against a 1990 baseline.
