This memorandum provides a preliminary assessment of the Climate Change Act 2008 ch. 27 (ISBN 9780105427087) The Act aims to create a legislative framework for the effective management and delivery of policies to tackle climate change, in particular by: a). establishing an economically credible emissions reduction pathway to 2050, by putting into statute medium and long-term targets and a system of carbon budgets; b). providing greater clarity and predictability for industry to plan effectively for, and invest in, a low-carbon economy; c). providing a strong evidence base and expertise to underpin statutory targets; d). establishing a duty on the Government regularly to assess the risks to the UK from climate change and draw up a programme to address them; and e. creating a power for the Government to require a range of public authorities or statutory bodies to assess and address the impacts of climate change. The memorandum concludes that the Act has created an effective legislative framework and is structured to provide a degree of flexibility, setting a framework to motivate and enable policy action without being too prescriptive about how the framework should be applied. This is required to address the inherent unpredictability around future emissions projections and to ensure that mitigation is not unnecessarily costly. In this vein, the Climate Change Act allows for a carbon budget level to be amended if it appears to Government that there have been significant changes affecting the basis on which the previous decision was made
