New buildings must be zero-emission and have solar panels by 2030, and fossil fuel boilers to be banned by 2040

New buildings in the EU must have no emissions from fossil fuels by 2030, and boilers that use those sources will be banned by 2040 under a new deal on energy and homes.

The rules, agreed between MEPs and member states but not yet formally adopted, set targets to make buildings waste less energy. Subsidies for standalone oil and gas boilers will stop by 2025.

Chris Bowen has indicated Australia may be willing to back a global commitment at the Cop28 climate summit to phase out fossil fuels.

The Australian climate change minister has also flagged that position may be unlikely to be adopted at the meeting in the United Arab Emirates unless it was attached to the word “unabated” – a controversial and undefined term usually taken to mean fossil fuels can continue if they are cutting their pollution through the use of carbon capture and storage (CCS).

‘We cannot negotiate with nature’ says Denmark’s climate minister as talks to phase out fossil fuels hang in balance

The next few days could be the world’s last chance of keeping global heating within safe limits, nations meeting for the Cop28 UN climate summit have been told.

With talks in Dubai now entering their final phase, the world’s governments are still far apart on the central question of whether to phase out fossil fuels.

Exclusive: Figures reveal growing push by fossil fuel sector for technologies that scientists say will not stop global heating

Cop28 organisers granted attendance to at least 475 lobbyists working on carbon capture and storage (CCS), unproven technologies that climate scientists say will not curtail global heating, the Guardian can reveal.

The figure was calculated by the Centre for Environmental Law (Ciel) and shared exclusively with the Guardian, and is the first attempt to monitor the growing influence of the CCS subset of the fossil fuel industry within the UN climate talks.

The Guardian asks five climate experts to explain the key differences between 1.5C and 2C

The world’s most ambitious climate target is under threat, both from physics and politics. But what would it mean for the planet and its inhabitants if humanity were to abandon the goal to limit global heating to 1.5C above preindustrial levels?

The inclusion of 1.5C (2.7F) was hailed as one of the great triumphs of the Paris climate agreement of 2015. Until then, international ambition had been limited to 2C (3.6F), much to the frustration of small island states and others on the frontline of climate disruption.

Exclusive: plant from South America, also known as Gunnera, found to spread rapidly and choke native flora

With its dramatic leaves and sprawling structure, the giant rhubarb has long been a popular garden plant, gracing the grounds of stately homes and multiple National Trust properties.

But the UK government is now to enact a ban – similar to that on Japanese knotweed – on the plant, also known as Gunnera, meaning it cannot be sold or cultivated, and those who have it in their gardens must ensure it does not spread.

Delegates return after rest day with children, education and food on the agenda

Canada has been asked by the Cop28 president, Sultan Al Jaber, to help develop language on the potential phase down or phase out of fossil fuels, its environment minister told reporters on Friday morning.

Steven Guilbeault, a former activist who is environment minister for the fourth largest oil and gas producer in the world, announced that Canada would require its fossil fuel industry to cut its emissions between 35% to 38% below 2019 levels starting in 2030 on Thursday.

Researchers warn of one of ‘largest ecological disasters of modern times’ if the highly contagious disease reaches penguin colonies

Bird flu is spreading in the Antarctic, with hundreds of elephant seals found dead, and fears it could bring “one of the largest ecological disasters of modern times” if the highly contagious virus reaches the remote penguin populations.

The virus was first reported among brown skua on Bird Island, off South Georgia. Since then, researchers and observers have reported mass deaths of elephant seals, as well as increased deaths of fur seals, kelp gulls and brown skua at several other sites. Cases have been confirmed 900 miles (1,500km) west of South Georgia, among southern fulmar on the Falkland Islands.

UN climate chief calls for ‘highest ambition’ as nations wrangle over draft agreement

Negotiations on how the world can slash greenhouse gas emissions and stave off the worst impacts of the climate crisis will reach a fresh intensity over the next few days, with nations wrangling over whether to phase out or phase down fossil fuels.

For the remaining five negotiating days of the Cop28 UN climate summit in Dubai ministers will hold a series of meetings to try to break the impasse and present a text that sets out a roadmap for staying within a rise of 1.5C of global heating above preindustrial levels.

Justin Trudeau’s government plans to limit emissions through a national cap-and-trade system, a policy first proposed in 2021

Canada will require its fossil fuel industry to cut its emissions between 35% to 38% below 2019 levels starting in 2030, it was announced on Thursday.

The prime minister Justin Trudeau’s government plans to limit emissions from the oil and gas sector through a national cap-and-trade system which he first proposed in his 2021 election campaign, according to the policy announcement.

2023 is first year of potential pair of El Niño years and since 1997, every instance of these pairs has led to mass coral mortality

Record-breaking land and sea temperatures, driven by climate breakdown, will probably cause “unprecedented mass coral bleaching and mortality” throughout 2024, according to a pioneering coral scientist.

The impact of climate change on coral reefs has reached “uncharted territory”, said Prof Ove Hoegh-Guldberg, from the University of Queensland, Australia, leading to concerns that we could be at a “tipping point”.

Effective governance of Britain’s nuclear industry is critical to saving a hazardous industry from itself

There will be many reasons why Britain’s energy secretary, Claire Coutinho, went public with her unease about “serious and concerning” allegations raised by the Guardian this week over cybersecurity, site safety and a “toxic” workplace culture in Sellafield. There was the “longstanding nature” of the matters in question, raising questions over the site’s management. Neighbouring governments have had serious concerns. The plant holds enough plutonium to potentially make thousands of atomic bombs of the size that obliterated Japan’s Nagasaki in 1945. By asking for assurances from its state-controlled owner and its regulator, Ms Coutinho emphasises that effective governance of Britain’s nuclear industry is a critical issue.

This is a sensible response to these scandals. The cabinet minister is right to publicise her concerns about a hazardous industry that can inflict catastrophic environmental damage and deaths. She has sent a helpful signal about valuing public safety over secrecy. Sellafield in Cumbria, and about 20 smaller sites, need to be monitored and protected, as the waste stored can remain radioactive for tens of thousands of years. Yet the nuclear establishment is at best opaque. Britain’s postwar development of nuclear weapons grew alongside the construction of nuclear energy reactors. The industry’s military connections have influenced its approaches to corporate governance for the worse.

The Australian government has pledged A$150m climate finance for Pacific countries, but has not contributed to a newly created global loss and damage fund.

Nearly 200 countries reached an historic consensus agreement on the first day of the Cop28 climate summit in Dubai to set up the loss and damage fund to help the world’s poorest and most vulnerable countries pay for the irreversible impacts of climate disaster.

Groups seek more time to comment on US Forest Service proposal to store carbon dioxide amid fears over safety and impact

A proposal that would allow industries to permanently stash climate-polluting carbon dioxide beneath US Forest Service land puts those habitats and the people in or near them at risk, according to opponents of the measure.

Chief among opponents’ concerns is that carbon dioxide could leak from storage wells or pipelines and injure or kill people and animals, as well as harm the trees in the forests and their habitat, said Victoria Bogdan Tejeda, attorney at the Center for Biological Diversity.

Exclusive: Five IPCC report authors say scientists should be allowed to make policy prescriptions and potentially oversee implementation

Senior climate experts are calling for an overhaul of the structure and powers of the UN’s Intergovernmental Panel on Climate Change in despair at the slow pace of climate action.

Five lead authors of IPCC reports told the Guardian that scientists should be given the right to make policy prescriptions and, potentially, to oversee their implementation by the 195 states signed up to the UN framework convention on climate change (UNFCCC).

As world leaders gather at Cop28, these charts show how far away the major economies are from their targets

Not a single G20 country has policies in place that are consistent with the Paris agreement’s goal of limiting global heating to 1.5C and meeting their “fair share” of emissions reduction.

The assessment, based on data up to 5 December provided by the Climate Action Tracker, comes as leaders gather in Dubai for the Cop28 conference.

Traditionally unpopular carbon taxes could be achieved with regulatory compliance, IMF head tells Cop 28

Diverting the trillions of dollars by which the world subsidises fossil fuel production each year, and putting an implicit price on carbon emissions, would generate the vast amounts of cash needed to tackle the climate crisis, the head of the International Monetary Fund has said.

Governments have been put off explicitly pricing carbon by the potential unpopularity of new carbon taxes, which have become favourite targets of anti-climate politicians and parties around the world, from the US and Australia to Europe and the UK.

The 80,000 delegates are thinking of how best to unwind from the climate summit ‘whirlwind’ in Dubai on their only day off

From the world’s largest waterpark to an indoor ski resort in a shopping centre, Cop28 delegates will have plenty of options to choose from on their only day off at the climate summit.

After an exhausting week of negotiations, events and protests, the 80,000 delegates in the United Arab Emirates will have a chance to enjoy Dubai ahead of the final push.
