Today, the Committee on Climate Change (CCC) publishes a report on the Fourth Carbon Budget. The report will kick of a review of the Budget which is expected to see political infighting within the coalition government. Background: Under the Climate Change Act 2008, the UK is legally committed to reducing its emissions of greenhouse gases by at least 80% by 2050 compared to 1990 levels. This target was set on the basis that this was the minimum action that the UK should be undertaking as part of a global effort to prevent dangerous levels of climate change. In order to reach its objective for 2050, the Act created an independent advisory body, the Committee on Climate Change (CCC). The main task of the CCC is to produce 5-yearly “carbon budgets”, which essentially set out the rate at which the UK’s emissions need to be reduced in a 5-year period and in what sectors of the economy. These budgets are normally issued and then approved by Government some 15 years ahead of the starting date of a budget. This allows for sufficient lead-in time to adopt the necessary policies to deliver the ambition set out in the budgets.
