Closed petition Repeal the Climate Change Act 2008 and Net Zero targets

We consider that Parliament must revoke The Climate Change Act 2008 and related Net Zero targets as since 2008 when the The Climate Change Act became law many hundreds of scientists up to the highest Nobel Laureate level have jointly declared "There is no climate emergency".

More details

We believe the Climate Change Act 2008 and related Net Zero targets are both now in effect based on just one side of a two-sided scientific debate as we do not consider there to be a scientific consensus on the hypothesis of human emissions causing climate change. We consider that one side only of a two-sided scientific debate is not an acceptable basis for significant legislation that could have major impacts of the UK's economy and citizens. We want the issue of Climate Change to be reconsidered from scratch based on views and evidence from all sides.

The Government’s policy to support ambitious action on climate change reflects the mainstream scientific consensus, and delaying action will only put future generations at risk.

The Government’s policy to support ambitious action on climate change reflects the mainstream scientific consensus and thousands of studies, including the Intergovernmental Panel on Climate Change (IPCC) assessments. The IPCC is the authoritative source of information on climate science. The IPCC has established that human influence has warmed the climate at a rate that is unprecedented in at least the last 2000 years. This warming of the climate is attributed to the build-up of carbon dioxide (CO2) and other greenhouse gases in the atmosphere due to fossil fuel combustion, cement manufacture and deforestation. The evidence for this is set out in chapters 2 and 3 of the IPCC Sixth Assessment Working Group 1 report. The IPCC Sixth Assessment reports can all be accessed here (

As discussed in chapter 4 of the above report, if the CO2 concentration continues to rise unchecked the world could face a global surface temperature rise of about 3°C or more above pre-industrial levels by the end of this century. The serious consequences of this for human societies and ecosystems are set out in the IPCC Working Group report on impacts, vulnerability, and adaptation.

The Prime Minister has reiterated that net zero is a priority for this Government. The UK is the first major economy to halve its emissions – having cut them by around 53% between 1990 and 2023, while also growing its economy by around 80%. More than ever, we are determined to adopt a fair and pragmatic approach to net zero that minimises the burdens on working people. The measures announced by the Prime Minister on 20th September 2023 ( will help avoid imposing significant costs on families.

The Government understands the importance of affordable energy bills for households and businesses and is focussed on delivering for energy consumers. We are taking a comprehensive approach to bring down future bills. This includes reforming retail markets to be more effective for consumers through the Review of Electricity Market Arrangements (REMA) Programme. We are also investing across the energy system and supporting the progress of new technologies to deliver a smarter energy system, and energy efficiency to reduce costs for all consumers.

The costs of global inaction to tackle climate change significantly outweigh the costs of action. Indeed, delaying action will only put future generations at risk. The Net Zero Review by HM Treasury, published alongside the Net Zero Strategy in October 2021, provided an analysis of the costs and benefits of the transition, found here ( As the Office for Budget Responsibility (OBR) noted in its July 2021 Fiscal Risks Report (, “the costs of failing to get climate change under control would be much larger than those of bringing emissions down to net zero”.

Government policy and spending ambitions will support up to 480,000 green jobs in 2030. We have a clear strategy to boost UK industry and reach net zero by 2050 – backed by £300 billion in public and private low carbon investment between 2010 and 2023, with a further £100 billion of private investment expected by 2030. Since September alone companies have announced plans for £30bn of new investment across the energy sector, including to advance green technologies and support green industries of the future.

The public will play a key role in the net zero transition. A significant proportion of the emission reductions will require the public to make green choices and the UK government will be supporting the consumers all the way. Our priority is making green choices significantly easier, clearer and more affordable, and working with industry to remove barriers.

The DESNZ Public Attitudes Tracker shows that people are willing to make green choices. In Summer 2023, a large majority (74%) agreed that they could make changes that would help reduce climate change. When shown a list of behaviours related to reducing climate change, almost all people (98%), said that they did at least one of these in their everyday life. The most recent wave of the DESNZ Public Attitudes Tracker ( shows that 80% of people in the UK are either fairly concerned or very concerned about climate change and 62% of the public consider climate change and the environment to be one of the most important issues facing the UK (ONS 14-25th February 2024

The Climate Change Act requires that we publish the level of the Carbon Budget 7 twelve years before the period to allow policy makers, businesses, and individuals to prepare. The statutory deadline for setting the Seventh Carbon Budget is June 2026. In recent correspondence with the Environmental Audit Committee, the Secretary of State for DESNZ stated her support for proper democratic consideration of carbon budgets. We have committed to additional Parliamentary scrutiny for Carbon Budget 7, which is in line with this government’s commitment to delivering on these targets in a way that brings people with us and ensures democratic debate about the way we get there.
