Edinburgh, Scotland: The newly published Scottish Climate Change Bill has the potential to become a world leading piece of legislation if it receives cross-party backing from Scottish MPs, according to WWF-Scotland. The targets in the bill include a 50 per cent reduction in greenhouse gas emissions by 2030 and a cut of 80 per cent by 2050. It also sets out measures to tackle shipping and aviation emissions, as well as emissions from all six greenhouse gases, not just carbon dioxide.
