Energy and Climate Change

Absolutely, I do. I accept that completely, and that is why the Government are determined to take decisive action. The consequences, however, of a 3.5° C to 4° C rise would be devastating, including a 2 metre rise in sea levels, a massive impact on food production and so on, but to hit the 2° C target we need global emissions to peak by 2020 and, after that, to reduce by 4% annually. That target is achievable if decisive action is taken by both the developed and the developing worlds, and this Government are determined to take a lead internationally —one of the things that the hon. Lady raised specifically —in seeking to achieve it. Developing countries on their own are likely to account for 60% of emissions by 2020 owing to rapid development, and the Government recognise that the European Union must show leadership, so we are pressing for a 30% 2020 emissions reduction target, rather than the current 20%. To answer the hon. Lady's specific question about whether we need to review the target level, I note that the Cancun conference agreed to a review of the science to see whether to adjust the target and whether the 2° C target is adequate to prevent the disastrous consequences of climate change. I acknowledge what she said about the outcome of the recent Durban conference, but it did make progress on the design of that review and on the steps, including negotiating a new global agreement, to get the global community back on track to achieve at least the 2° C goal. I pay tribute to my right hon. Friend the Secretary of State for Energy and Climate Change for playing a key role in the Durban negotiations, which have taken things forward. All that sets the context—the imperative of building a low-carbon economy—for dealing with the contributions from the hon. Members for Warrington South (David Mowat), for Daventry (Chris Heaton-Harris) and for Montgomeryshire (Glyn Davies). Not only do we need to reduce carbon emissions because of the imperative of tackling climate change, but we face the massive challenge of energy security. I shall deal first with the hon. Member for Warrington South, who criticised the focus on renewables and sought to concentrate on the optimisation of decarbonisation, arguing for the importance of nuclear and gas in the short term. We face the immediate and remarkable challenge that nearly one third of our energy supplies will be going off-grid in the next decade. That is because of decisions already taken. Nuclear cannot deliver in that time frame. There are disadvantages in relying heavily on imported gas because it makes us more vulnerable to risks with regard to security of supply, fluctuating and volatile cost, and availability of supply. To replace the lost capacity and to hit challenging emissions targets, we need a new supply quickly, and wind and other renewables are a crucial part of that. Over the longer term, the Government have no intention of favouring one form of low-carbon energy production over another. Our intention is to secure a level playing field for low-carbon technologies competing with one another. Tidal power, which was mentioned by the hon. Member for Montgomeryshire, should be given its chance along with other technologies. The Government have already issued a White Paper on electricity market reform. That is an important way to deliver the change that we need to secure proper competition between low-carbon technologies. It will mean that a level playing field is introduced by 2020, and it covers nuclear, carbon capture and storage, and renewables. The carbon plan published on 1 December, which sets out how we will meet the requirements of the fourth carbon budget—between 2022 and 2027—does not favour one form of production over another but offers different scenarios and different combinations within the whole mix. We are not looking to lock in any one form of production. The Government have stressed the importance of reducing energy demand and of improved energy conservation. That is why our green deal is so important, as is the radical step of introducing smart electricity and gas meters across every home. We do, however, stress the need for immediate and decisive action.
