This programme sets out the Government's policies and priorities for action on climate change in the UK and internationally. The first section examines the nature and scale of the challenge posed by climate change. It describes the existing international framework for action, including the G8 and EU meetings and resulting plans of action. The Government intends to build on these developments, and also try to influence the rapidly growing economies of India, China, Brazil and others so that they evolve as low-carbon economies. The major part of the report is concerned with the UK's attempt to deliver the Kyoto Protocol target of reducing emissions of six greenhouse gases by 12.5 per cent below base year levels over the 2008-2012 period, and also the domestic goal of reducing carbon dioxide emissions by 20 per cent below 1990 levels by 2010. Projections indicate that CO2 reduction by 2010 will only be some 10.6 per cent below the 1990 level. Sections on the UK emission inventory and projections, the strategy to reduce emissions, and the energy supply sector, are followed by chapters covering particular economic sectors: business; transport, domestic; agriculture and forestry; the public sector. Among policies outlined here are: encouragement of microgeneration and renewable sources of energy; investigation of carbon capture and storage; support for energy efficiency in business, local and central government; increase uptake of biofuels; include aviation in the emissions trading scheme for the EU from 2008; raise energy standards of new and refurbished buildings; introduce the Code for Sustainable Homes; strengthen consumer demand for energy efficiency. The Government also sets out its approach to encourage personal action, as citizens, consumers, motorists and business people. Provision of better information to the public, including an online service on the environmental impact of everyday products and services, will be supplemented by a plan for action on sustainable consumption by the end of 2006.

This publication contains oral and written evidence taken before the Committee in their inquiry into the Government's Climate Change Programme announced in March 2006 (in its White Paper 'Tomorrow's Climate, Today's Challenge' Cm. 6764, ISBN 0101676425). It includes contributions from officials from Defra, the Confederation of British Industry, the UK Sustainable Development Commission, Greater London Authority and local authorities.

White paper.

The Scheme is part of the Government's climate change programme, which is designed to secure significant reductions in UK greenhouse gas emissions, believed to cause global warming. Under the Scheme, companies are issued with allowances equal to their target emissions for the year, and at the end of the year must hold enough allowances to cover its actual emissions. A company can choose to reduce its actual emissions below its target (enabling it to sell excess allowances to other companies, or to save them for use in future years), to meet its target, or to buy extra allowances to cover any emissions in excess of its target amount. This NAO report examines the Scheme's origins, impact and wider benefits, based upon consultation with participating companies and other stakeholders, case studies involving four of the biggest companies involved, and advice of an expert panel and assistance from specialist consultants. Overall, the report concludes that the Scheme is a pioneering initiative that has encouraged participants to identify emissions reductions, and has potential to benefit the UK economy. However, the fact that the Scheme is a voluntary one has led to difficulties in attracting participants and setting demanding targets. A number of recommendations are made to improve the existing UK Scheme and to help develop European trading schemes, including raising the value obtained from incentive payments and ensuring lessons are learned from the experience of the Scheme in any further developments or in the design of new environmental trading schemes.

This document sets out the Government's response to the public consultation on the draft Climate Change Bill (Cm. 7040, ISBN 9780101704021) and to the reports of the following Parliamentary Committees during session 2006-07: the Joint Committee on the Draft Climate Change Bill (HLP 170-I/HCP 542-I, ISBN 9780104011379); the Environment, Food and Rural Affairs Committee (HCP 534-I, ISBN 9780215034892); and the Environmental Audit Committee (HCP 460, ISBN 9780215035561). The Climate Change Bill seeks to introduce a clear, credible and long-term framework to support emissions reductions in the UK, designed to maximise the social and economic benefits and minimise costs, and also sets out an international precedent, reinforcing the UK's position as a consistent leader in the field of climate change and energy policy. This document explains the main changes the Government intends to make to the Bill, taking into account the consultation responses and the recommendations of the three Parliamentary Committees, and key elements of the Bill include: putting into statute the UK's domestic targets to reduce carbon dioxide emissions through domestic and international action by at least 60 per cent by 2050, and 26 to 32 per cent by 2020, against a 1990 baseline; secondary legislation to set binding limits known as carbon budgets on aggregate carbon dioxide emissions over five year periods; and the creation of a new independent body, the Committee on Climate Change, to advise on setting carbon budgets.

This report is about how the Government: sets targets for reductions in UK green house gases; assess progress towards these targets by forecasting the likely levels of future emissions; choose policy instruments to deliver the requisite cuts in emissions; and revises its package of policies in the light of experience. It is two main parts, the first looks at the Climate Change Programme Review, whilst the second examines the proposed Climate Change Bill. The Climate Change Programme Review revealed a number of weaknesses in the UK climate change policy as it became apparent that the target of a 20% reduction in carbon emissions by 2010 would be missed. Revisions to the projection of emissions had not been done frequently enough, so by the time Ministers knew there were problems it was too late to introduce new measures. The programme is however likely to be rescued, somewhat, by Phase II of the EU Emissions Trading Scheme, which promises to deliver some real savings. The draft Climate Change Bill, alongside other developments such as the creation of the Office of Climate Change and requirements of the Climate Change and Sustainable Energy Act 2006, are broadly well designed and a far-reaching responses to these issues.

Climate change resulting from CO2 and other greenhouse gas emissions poses a huge threat to human welfare. To contain that threat, the world needs to cut emissions by about 50 per cent by 2050, and to start cutting emissions now. A global agreement to take action is vital. A fair global deal will require the UK to cut emissions by at least 80 per cent below 1990 levels by 2050. In this report, the Committee on Climate Change explains why the UK should aim for an 80 per cent reduction by 2050 and how that is attainable, and then recommends the first three budgets that will define the path to 2022. But the path is attainable at manageable cost, and following it is essential if the UK is to play its fair part in avoiding the far higher costs of harmful climate change. Part 1 of the report addresses the 2050 target. The 80 per cent target should apply to the sum of all sectors of the UK economy, including international aviation and shipping. The costs to the UK from this level of emissions reduction can be made affordable - estimated at between 1-2 per cent of GDP in 2050. In part 2, the Committee sets out the first three carbon budgets covering the period 2008-22, and examines the feasible reductions possible in various sectors: decarbonising the power sector; energy use in buildings and industry; reducing domestic transport emissions; reducing emissions of non-CO2 greenhouse gases; economy wide emissions reductions to meet budgets. The third part of the report examines wider economic and social impacts from budgets including competitiveness, fuel poverty, security of supply, and differences in circumstances between the regions of the UK.
