Prime Minister agrees legally binding net-zero emissions target for 2050

Announced on Tuesday night (11 June), the Prime Minister revealed that the statutory instrument to amend the Climate Change Act of 2008 to account for a net-zero target by 2050 will be laid in Parliament on Wednesday.
Prime Minister Theresa May said: “Now is the time to go further and faster to safeguard the environment for our children. This country led the world in innovation during the Industrial Revolution, and now we must lead the world to a cleaner, greener form of growth.
“Standing by is not an option. Reaching net zero by 2050 is an ambitious target, but it is crucial that we achieve it to ensure we protect our planet for future generations.”
The move comes just over a month after the Committee on Climate Change (CCC) published its recommendations to Government on legislating for a net-zero carbon economy. The body’s advice includes bringing the ban on new petrol and diesel car sales forward to 2035; quadrupling the UK’s renewable energy generation capacity; improving biodiversity across 20,000 hectares of land annually and deploying carbon capture and storage (CCS) at scale.
Crucially, the CCC believes that reaching net-zero by 2050 can be done using between 1-2% of GDP in 2050. This is the same level of funding currently allocated to work related to compliance with the Climate Change Act.
Devil in the detail
How the UK actually plans to reach net-zero emissions will need to be set out. Chancellor of the Exchequer Philip Hammond claimed that spending cuts for schools, hospitals and the police force would be needed to fund total decarbonisation of the UK economy, which he estimated at £1trn.
The Financial Times reported last week (4 June) that the cabinet has accepted a request by Hammond that 88 megatonnes (million tonnes) of emissions from the 2013 to 2017 carbon budget should be carried forward to give the UK more leeway in meeting future targets. The decision flies in the face of advice issued by the CCC when it urged ministers not to take advantage of the existing rule.
Under the Climate Change Act, the UK is currently targeting an 80% reduction in emissions by 2050 against a 1990 baseline, following similar advice from the CCC in the past. However, the current Act only accounts for international aviation and shipping on a territorial basis. Under the proposed new strategy, the net-zero target would encompass all sectors, including shipping and aviation.
One deviation from the recommendations is the use of international carbon credits. The UK Government has confirmed that they will retain the ability to use these credits to offset emissions within an appropriate monitoring, reporting and verification framework.
The UK Government also looks set to stick with its original phase-out date for new diesel and petrol vehicles. However, MPs have confirmed a bid host COP26.
The Government’s target will also tap into the growing influence of youth climate strikes. A Youth Steering Group will be led by DCMS and the British Youth Council to advise the Government on priorities for climate change, waste and recycling and biodiversity loss. They will start their review in July.
The legislation means the UK will become the first G7 nation to enshrine a net-zero target, and will conduct assessments within the next five years to push for other countries to set similar targets. A key ambition of this assessment is to ensure that UK industries to not face unfair competition from foreign businesses neglecting climate impacts.
Rapid turnaround
It also follows months of calls from MPs and businesses alike to enshrine a net-zero target into UK law – a discussion that has been amplified by the recent climate school strikes and Extinction Rebellion protests.
The announcement from the Government comes just hours after the Business, Energy and Industrial Strategy (BEIS) committee’s chair Rachel Reeves MP introduced a new bill for legislating on net-zero to the House on Tuesday afternoon (11 June).
The bill, which followed the CCC’s recommendations and included all international aviation and shipping, was broadly welcomed across the house – particularly by groups such as the Environmental Audit Committee (EAC).
Path to net-zero
The UK Government first requested advice from the CCC on how best to legislate for a net-zero carbon economy last Autumn, in the wake of the Intergovernmental Panel on Climate Change’s (IPCC) landmark report on global warming.
The report shed light on the vast difference in economic, social and environmental impacts between the Paris Agreement’s agreed 1.5C and 2C pathways for the first time, revealing that the 0.5C difference would significantly worsen the risks of drought, floods, extreme heat and poverty for hundreds of millions of people. In order to limit warming to 1.5C, the paper concluded, global emissions would need to be cut by 45% by 2030 before reaching zero in 2050.
In the wake of the report, Scotland has already legislated to hit net-zero by 2045, while Wales has legislated for a 95% cut to national emissions by the same deadline. On a global level, efforts to reduce emissions have seen a 1C drop in the temperature rise being forecast by the end of the century – from 4C to around 3C.
From a business perspective, several of the UK’s largest corporates have also set their own pre-2050 net-zero or 1.5C targets in light of the IPCC’s claims, including the likes of BT, Skanska UK, Ecotricity and Aldi UK and Ireland. This trend can be seen across the global business community too, with modular flooring firm Interface, engineering and electronics giant Bosch and container shipping giant Maersk among the global cohort of so-called “zeronauts”.
Businesses from all sectors and of all sizes have also been aiming to drive change outside of their own operations by lobbying the UK Government to legislate for net-zero. Last month, a coalition of 128 UK-based businesses, industry networks and investors wrote to Ministers demanding that a net-zero target for 2050 is legislated “immediately” and were told such moves would be made “in a timeframe which reflects the urgency of the issue”.
Commenting on the introduction of the legally binding target, Secretary of State for Business, Energy and Industrial Strategy Greg Clark said: “We want to continue our global leadership and that’s why we are introducing a legally binding net zero target to end the UK’s contribution to global warming entirely by 2050. The report we commissioned from the Committee on Climate Change makes clear that we have laid the foundations to achieve a net zero emissions economy, and that it is necessary and feasible.
“Almost 400,000 people are already employed in the low-carbon sector and its supply chains across the country. Through our modern Industrial Strategy we’re investing in clean growth to ensure we reap the rewards and create two million high quality jobs by 2030.”

STOCKHOLM – Earlier this month, a bleak global assessment of the shocking state of life on Earth made headlines worldwide. According to the report by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), about 12% of all known animal and plant species are now threatened with extinction. Worse still, humanity is destroying entire habitats, and with them the web of life that supports societies and economies. Unsurprisingly, the findings were greeted with despair.
As IPBES scientific contributors and co-authors of the report, we face this news every day. It is impossible not to react emotionally to the scale of destruction humans are inflicting on the natural world. Yet the report also goes to great lengths – although this has been less widely reported – to identify ways to reverse this alarming trend. To succeed, however, humans need to undertake four major transformations.
First, we must substantially change our legal, economic, and technological systems. It is true, as the report emphasizes, that protected areas and legislation have prevented the extinction of many species, such as the panda. And further conservation steps are clearly needed. But humans need to make far more fundamental changes.
The IPBES report therefore explores numerous possible economic development paths for the world to 2050, and identifies ways to protect nature while increasing human prosperity. The measures it proposes are not the usual suspects, such as reducing deforestation or curtailing the exploitation of species; instead, they address the causes of these problems.
Here, the report concludes that sustaining Earth’s living systems requires us to redefine what a good quality of life means. Societies need to get away from the idea that a good and meaningful life is possible only through ever-increasing material consumption. This is clearly absurd. Wellbeing has been stagnating in many developed countries, even as consumption continues to increase.
Solutions could instead build upon new social and political narratives showing that happiness goes hand in hand with lowering total consumption and cutting waste. Reducing gender and wealth inequalities also improves a society’s wellbeing, as Nordic countries have shown. And, as IPBES recognizes, indigenous and local knowledge can reveal other ways of managing ecosystems sustainably.
Undertaking such shifts will not be easy. The world must urgently adopt a new economic paradigm that goes beyond a singular focus on GDP. This is beginning to happen. New Zealand, for example, has announced its first “wellbeing budget,” while China is continuing to develop measures of “green GDP.”
Second, the world must transform its food system. The way we currently produce and consume food is a major cause of ecological destruction. Yet feeding a growing global population a healthy diet without damaging the Earth is not only possible, but will also improve people’s quality of life. The IPBES report highlights several sustainable agricultural practices, such as integrated pest and nutrient management, organic farming, soil and water conservation, and measures to improve animal welfare.
One of the IPBES report’s development paths to 2050 is in line with the findings of the separate EAT-Lancet Commission reporton sustainable food systems. That report, released earlier this year, concluded that the world could feed ten billion people a healthy diet – with less meat and dairy products, and more nuts and vegetables – without needing to use more land.
But these actions on their own will not be enough. One-third of all food produced never makes it to the plate. We support calls for food waste to be slashed by 50% by 2030, and, encouragingly, countries including France, Germany, and Italy have taken steps to prevent supermarkets from discarding unsold food.
Third, we must treat the world’s oceans far better. Industrial fishing now extends to 55% of the world’s ocean area, and just 3% is free from human pressure. The ocean is increasingly used as a dumping ground for sewage, plastic, excess fertilizers, and other toxic pollutants. But research shows that managing the oceans sustainably can increase fish stocks and economic value. And the UN aims to reach agreement next year on new international regulations to protect the oceans.
Finally, the world must think carefully about the best ways to tackle climate change. The timber and agriculture industries – in particular the production of soy, palm oil, and beef – are causing rapid deforestation, with devastating consequences for the stability of the Amazon rainforest, the world’s climate, and many species. But attempts to combat global warming through large-scale planting of bioenergy crops, along with reforestation and afforestation, could greatly harm biodiversity and fragile ecosystems. Well-planned measures, on the other hand, could enhance biodiversity, improve soil quality, and capture and store carbon dioxide.
Protecting the living world calls for systemic changes that go beyond narrowly focused policies on biodiversity or climate. Fighting poverty and inequality are essential parts of the solution, too. But these transformative steps will happen only if we start treating the situation like the crisis it is, as Swedish climate activist and student Greta Thunberg has urged.
In recent weeks, both the UK and Irish parliaments have declared climate and nature emergencies, and we urge other countries to do the same. In 2020, a “superyear” for international environmental policy – with major summits on biodiversity, climate, and the oceans – the UN should mark its 75th anniversary by declaring an emergency for the planet to accelerate action to ensure long-term sustainability.
