UK ministers met fossil fuel lobbyists 500 times in first year of power, analysis shows

Lobbyists attended 48% more meetings than Tories, as Labour accused of giving them ‘backstage pass’

Government ministers met representatives from the fossil fuel industry more than 500 times during their first year in power – equivalent to twice every working day, according to new research.

The analysis found that fossil fuel lobbyists were present at 48% more ministerial meetings during Labour’s first year in power than under the Conservatives in 2023.

Ministers at the Department for Energy Security and Net Zero (DESNZ) met fossil fuel lobbyists 274 times, with industry figures present at almost a quarter of meetings.

Ed Miliband, the secretary for energy and climate change, met fossil fuel lobbyists 250 times – with a third of all his meetings attended by industry figures.

During the same period DESNZ ministers met trade union representatives 61 times

Three fossil fuel companies: BP, Shell and Equinor , met ministers 100 times between them.

Fossil fuel lobbyists attended almost every government meeting about the energy profits levy, a temporary windfall tax on the “extraordinary profits” of North Sea oil and gas companies.

Australian tropical rainforest trees switch in world first from carbon sink to emissions source

Researchers say carbon emissions change in Queensland tropical rainforests may have global climate implications

Australian tropical rainforest trees have become the first in the world to switch from being a carbon sink to an emissions source due to increasingly extreme temperatures and drier conditions.

The change, which applies to the trees’ trunks and branches but not the roots system, began about 25 years ago, according to new research published in Nature.

Wednesday briefing: The new, devastating flood risk facing nearly all of Britain

In today’s newsletter: Flooding is predicted to become so bad that some towns may need to be abandoned, and it’s not even campaigners raising the alarm – but insurers

Good morning. For years, whenever I read about parts of Britain being wrecked by flooding, it always felt like something distant – because until your house is flooded, it’s hard to imagine it happening, isn’t it? Not any more.

According to a Guardian investigation, millions more homes across England, Scotland and Wales are at risk of devastating floods. In England alone, the number of properties exposed to flooding is expected to rise by more than a quarter, from 6.3m to 8m. The story gets worse for those in high-risk areas for flash flooding – which is harder to predict and protect against – where the frequency could surge by up to 66% by 2050. The picture is so bleak that, startlingly, some towns may one day have to be abandoned altogether.

Israel-Gaza war | The fragile ceasefire in Gaza faced its first test on Tuesday when Israel said the flow of aid into the devastated Palestinian territory would be cut by half and the crucial Rafah border crossing with Egypt would not open as planned, blaming Hamas for delays in the return of bodies of hostages.

UK child abuse inquiry | Keir Starmer’s national grooming gangs inquiry has stalled amid wrangles over its remit and difficulties in finding a senior legal figure willing to become its chair, the Guardian has been told.

Economics | The global economy has shown “unexpected resilience” to Donald Trump’s tariffs, but the full impact is yet to be felt, the IMF has warned. The forecast for economic growth in the UK has also been modestly increased, from 1.2% to 1.3% this year – though slightly downgraded next year, also to 1.3%.

Madagascar | Andry Rajoelina, the president of Madagascar, has said he fled the country in fear for his life after a military rebellion but did not announce his resignation in a speech broadcast on social media. They were Rajoelina’s first public comments since the a military unit called Capsat turned against his government in an apparent coup.

Music | D’Angelo, the Grammy-winning R&B singer who helped pioneer the sound of neo-soul, has died after a struggle with pancreatic cancer. He was 51.

Plantwatch: An extraordinary orchid that lives and flowers underground

Botanist trying to conserve highly vulnerable rhizanthella that survives by feeding on nutrients from a fungus

Rhizanthella is an extraordinary orchid that lives its entire life underground. It flowers below ground, has no leaves and survives by feeding on nutrients from a fungus that gets its food from the soil and by connecting with roots of the broom bush, Melaleuca uncinata.

Rhizanthella was an international sensation when it was first discovered by a farmer ploughing a field in Western Australia in 1928. It still remains incredibly difficult to find, usually by searching areas with the right habitat and carefully scraping away soil searching for the blooms buried underneath – tiny reddish flowers wrapped in creamy-pink bracts. The blooms also have a heady scent of vanilla, and may be pollinated by termites or tiny flies.

Switching 50km/h speed limits to 30km/h would protect cyclists while barely affecting commutes, research finds

One expert says a cyclist hit by a car travelling 50km/h has about a one-in-ten chance of surviving, while at 30km/h it was a nine-in-ten chance

Reducing residential speed limits from 50km/h to 30 km/h would protect cyclists from danger and make riding less stressful while not causing traffic delays for cars, according to new research.

Researchers from RMIT University rated traffic stress levels for every road in greater Melbourne and modelled the effect of lower speed limits on bicycle and car travel.

Carmakers chose to cheat to sell cars rather than comply with emissions law, ‘dieselgate’ trial told

Mercedes, Ford, Renault, Nissan and Peugeot/Citroën face group action in which damages could exceed £6bn

Car manufacturers decided they would rather cheat to prioritise “customer convenience” and sell cars than comply with the law on deadly pollutants, the first day of the largest group action trial in English legal history has been told.

More than a decade after the original “dieselgate” scandal broke, lawyers representing 1.6 million diesel car owners in the UK argue that manufacturers deliberately installed software to rig emissions tests.

Planet’s first catastrophic climate tipping point reached, report says, with coral reefs facing ‘widespread dieback’

Unless global heating is reduced to 1.2C ‘as fast as possible’, warm water coral reefs will not remain ‘at any meaningful scale’, a report by 160 scientists from 23 countries warns

The earth has reached its first catastrophic tipping point linked to greenhouse gas emissions, with warm water coral reefs now facing a long-term decline and risking the livelihoods of hundreds of millions of people, according to a new report.

The report from scientists and conservationists warns the world is also “on the brink” of reaching other tipping points, including the dieback of the Amazon, the collapse of major ocean currents and the loss of ice sheets.

Australia’s household energy bills will halve by 2050, modelling suggests

Grattan Institute report argues fall in costs will provide federal government room for more action on climate

Australian household energy bills will halve by 2050 as solar panels, batteries and electric cars and appliances become the norm, reducing pressure on the federal government over living costs and creating room for more climate action, a thinktank study suggests.

Modelling by the Grattan Institute finds that cutting greenhouse gas emissions from electricity generation in line with the goal of reaching net zero emissions by 2050 will cut average household energy costs from about $5,800 today to about $3,000.
