Having good chance of limiting global heating to 1.5C is gone, sending ‘dire’ message about the adequacy of climate action
The carbon budget remaining to limit the climate crisis to 1.5C of global heating is now “tiny”, according to an analysis, sending a “dire” message about the adequacy of climate action.
The carbon budget is the maximum amount of carbon emissions that can be released while restricting global temperature rise to the limits of the Paris agreement. The new figure is half the size of the budget estimated in 2020 and would be exhausted in six years at current levels of emissions.
For more than a decade, the village of Bourakébougou in western Mali has been powered by a clean energy phenomenon that may soon sweep the globe.
The story begins with a cigarette. In 1987, a failed attempt to drill for water released a stream of odourless gas that one unlucky smoker discovered to be highly flammable. The well was quickly plugged and forgotten. But almost 20 years later, drillers on the hunt for fossil fuels confirmed the accidental discovery: hundreds of feet below the arid earth of west Africa lies an abundance of naturally occurring, or “white”, hydrogen.
Today, it is used to generate green electricity for Bourakébougou’s homes and shops. But geologists believe that untapped reservoirs of white hydrogen in the US, Australia and parts of Europe have the potential to provide the world with clean energy on a far greater scale.
Rich nations’ unwanted clothes often end up in landfills, polluting the global south. But entrepreneurs in Ghana, Pakistan and Chile are turning rubbish into rugs, shoes and toys
Every second, the equivalent of a lorry full of clothes ends up on a landfill site somewhere around the world. People are buying, and casting off, more clothes than ever. On average, each consumer buys 60% more clothing than 15 years ago and 92m tonnes of textile waste are created annually.
Production and consumption are on the rise, with severe environmental and social implications. Only 12% of the material used for clothing is recycled. A popular way to dispose of clothes is to give them to charity shops.
But many of these donations end up in countries in the global south, where there is big trade in second hand clothing.
The zero-emission fuel may exist in abundant reserves below ground. Now large sums are being invested to look for it

Lyrics of Stop changed to ‘stop right now, no more oil and gas’ because of bank’s fossil fuel funding
Dozens of activists from groups including Fossil Free London and Extinction Rebellion UK began their action less than five minutes into the meeting where its chair, Nigel Higgins, was addressing shareholders at the QEII Centre in Westminster, central London.
A choir was the first to interrupt, with a rendition of the Spice Girls song Stop. Reworking the 90s classic’s lyrics, the group sang: “Stop right now, no more oil and gas, stop burning fossil fuels and end this madness … hey you, burning up the Earth, gotta stop it now baby we have had enough … you dirty, dirty bank.”

Efforts to make flying greener mostly count carbon dioxide emissions only, but modelling shows this ignores 90 per cent of future flights’ contribution to climate change
Planes queueing for take-off
Future flights will endanger the goals of the Paris climate agreement if efforts to achieve net-zero aviation fail to account for the warming effect of streaks of clouds created by planes, a study has found.
The research comes just days after the UK government announced its Jet Zero Strategy on 19 July, with a target of reducing carbon emissions from flights to net zero by 2050.
Nicoletta Brazzola at ETH Zurich in Switzerland and her colleagues found that even if such efforts to reduce carbon emissions succeed, the aviation sector worldwide could increase global average temperatures by between 0.1°C and 0.4°C. Because the world has already warmed 1.1°C since the industrial revolution, Brazzola ’s team says the extra warming could compromise the Paris deal’s aim of holding temperature rises to 1.5°C.
The warming comes from the ways flights heat the atmosphere beyond the carbon dioxide emitted by burning jet fuel, which are the only emissions currently counted by international and most national efforts to decarbonise aviation. The main one of these non-CO2 effects is the contrails that form because of the soot, aerosols and water vapour released by aircraft engines.
“We found the mitigation efforts needed to get aviation to a place where it’s compatible with the Paris agreement are enormous,” says Brazzola.
Despite a study claiming that food-mile emissions are higher than previously thought, eating less animal produce remains much more important than how far your food travels
Eat locally to reduce food miles and your carbon footprint. That is the message promoted by some environmentalists and businesses, but it has long been clear that often this isn’t true – foods that travel thousands of kilometres can have a lower carbon footprint than local produce.
At least, that is what many studies have found. But research published today in the journal Nature Food claims that global food miles account for 20 per cent of food-related emissions – a much higher proportion than reported in earlier work. So do food miles matter more than we thought? Spoiler: no, they don’t.
The production of the food we eat is responsible for more than a third of global greenhouse gas emissions, so reducing food-related emissions is crucial to limiting further global heating. The question is, what should consumers do to help reduce these emissions?
Previous studies have found that the emissions from food miles – the distance that food has to be transported from where it is produced to where it is eaten, measured in kilometres travelled multiplied by the tonnage – are tiny compared with those from growing that food.
Emissions can be calculated based on how the food is transported – by air or by sea, for instance. A study of US diets by researchers at Carnegie Mellon University in Pennsylvania concluded that transporting food from farms to shops produces just 4 per cent of food-related emissions, while a 2018 study of European diets put it at 6 per cent.
What this means is that if you want to reduce the carbon footprint of your diet, you should focus on buying foods with lower overall carbon footprints rather than those that don’t have to travel far. This basically means eating less meat and dairy.
For instance, producing 1 kilogram of beef can emit as much as 99 kg of carbon dioxide or equivalents, and making a kilogram of cheese emits up to 24 kg, compared with 0.9 kg for bananas and 0.4 kg for apples.
In other words, what you eat matters to a far greater extent than where it comes from. What’s more, even with the same food types, local isn’t always better. For instance, if you live in a nation with a cooler climate where tomatoes can be grown only using heated greenhouses, these local tomatoes will typically have a higher carbon footprint than those shipped in from a warmer country where no heating is needed.
The latest study doesn’t overturn any of this. For starters, the main reason why it concludes that food miles account for such a high proportion of food-related emissions is that the 20 per cent figure includes all the transport involved, including that of fertilisers, farm equipment and pesticides, not just the transport of food.
“Our study looks at the entire supply chain for food consumption, and naturally non-food commodities are part of it,” says team member Mengyu Li at the University of Sydney in Australia.
It is worthwhile to estimate this, but the team should use a term other than “food miles” to avoid confusion, rather than redefining the existing term, says Hannah Ritchie at the University of Oxford, who is head of research at Our World in Data.
If the standard definition were applied to the numbers in the study, food miles would account for only 9 per cent of food-related emissions, says Ritchie. That is much closer to previous research, though she thinks it is still an overestimate.
What’s more, the study itself calculates that even if it were possible to produce all food in the countries where it is eaten, food-related emissions would fall by only 1.7 per cent overall. This is because although food wouldn’t travel as far, more of it would be transported by road instead of sea, says Li, and trucks produce higher emissions per tonne of cargo than ships.
“So, overall, the bottom line is still that what you eat has a much bigger impact on emissions than the distance that food has to travel to reach you,” says Ritchie.
The UN secretary general has told new university graduates not to take up careers with the “climate wreckers” – companies that drive the extraction of fossil fuels.
António Guterres addressed thousands of graduates at Seton Hall University in New Jersey, US, on Tuesday. “You must be the generation that succeeds in addressing the planetary emergency of climate change,” he said. “Despite mountains of evidence of looming climate catastrophe, we still see mountains of funding for coal and fossil fuels that are killing our planet.
“But we know investing in fossil fuels is a dead end – no amount of greenwashing or spin can change that. So we must put them on notice: accountability is coming for those who liquidate our future.”
He added: “You hold the cards. Your talent is in demand from multinational companies and big financial institutions. You will have plenty of opportunities to choose from. My message to you is simple: don’t work for climate wreckers. Use your talents to drive us towards a renewable future.”
Guterres has become increasingly outspoken on the climate crisis in recent months, telling world leaders in April: “Our addiction to fossil fuels is killing us.”
Caroline Dennett tells staff in video she made decision because of ‘double-talk on climate’
A senior safety consultant has quit working with Shell after 11 years, accusing the fossil fuel producer in a bombshell public video of causing “extreme harms” to the environment.
Caroline Dennett claimed Shell had a “disregard for climate change risks” and urged others in the oil and gas industry to “walk away while there’s still time”.
The executive, who works for the independent agency Clout, ended her working relationship with Shell in an open letter to its executives and 1,400 employees. In an accompanying video, posted on LinkedIn, she said she had quit because of Shell’s “double-talk on climate”.
Environmental campaigners are suing the Dutch airline KLM over “greenwashing” adverts they say misleadingly promote the sustainability of flying.
Lawyers from ClientEarth are supporting Fossielvrij NL, a Netherlands-based campaign group, to bring a claim that KLM’s ad campaigns give a false impression of the sustainability of its flights and its plans to address its impact on the climate.
“KLM’s marketing misleads consumers into believing that its flights won’t worsen the climate emergency. But this is a myth,” said Hiske Arts, a campaigner at Fossielvrij NL.
“Unchecked flying is one of the fastest ways to heat up the planet. Customers need to be informed and protected from claims that suggest otherwise.”
Activists from Fossielvrij NL submitted a pre-action letter to Air France KLM, KLM’s parent company, during its AGM in Paris on Tuesday. Their legal action takes aim at KLM’s “Fly Responsibly” campaign, which presents the airline as “creating a more sustainable future”.
The system of executive pay is “broken”, the Church of England’s pension board has said, as it challenged more companies to ease the pain of soaring inflation by committing to paying workers the living wage.
Frustrated with the Australian government’s inaction on climate change, software king Mike Cannon-Brookes is trying to buy several big coal plants so he can shut them down in favour of renewables
Mike Cannon-Brookes, the third-richest person in Australia, has launched an audacious bid to buy the country’s biggest electricity company – and shut its coal-fired power plants. It is a bold approach to decarbonisation, but can he pull it off?
Australia currently produces the highest carbon emissions per capita in the world from burning coal for power generation. The country’s government is highly attached to fossil fuels. Not long before becoming the current prime minister, Scott Morrison brought a lump of coal to parliament and announced: “This is coal. Don’t be afraid, don’t be scared, it won’t hurt you.”
Cannon-Brookes, co-founder of software giant Atlassian, has been a vocal critic of the government’s climate inaction. Now, he is using his net worth of A$20 billion to try to take matters into his own hands.
