Key developments
Roadless rule
ROADLESS RULE NO MORE: The US agriculture department announced last week that it plans to “rescind a decades-old rule that protects 58.5m acres [236,741km2] of national forestland from road construction and timber harvesting”, the Los Angeles Times reported. The “Roadless Rule” has been in place since 2001 and “established lasting protection for specific wilderness areas within the national forests”, the outlet continued. US agriculture secretary Brooke Rollins called the rule “outdated”, while environmental groups “condemned the decision and vowed to take the administration to court”, according to the Washington Post.
PUBLIC LANDS PRESSURE: Amid Republican opposition, Utah senator Mike Lee pulled his “controversial proposal” to sell off public lands for housing developments from the “sprawling” domestic policy bill known as the “Big Beautiful Bill”, the Salt Lake Tribune reported. According to Politico, Lee blamed “misinformation” for the provision’s lack of support, even though, “in reality, he faced stiff opposition from western Republicans from states with large public land holdings”. On Tuesday, the Senate “narrowly approved” the bill, which now has to return to the House – where “many members have balked at the Senate’s changes to the measure” – for further approval, the Washington Post said.
BACK ONLINE: The Famine Early Warning Systems Network (FEWS NET) is back online following a “months-long shutdown” due to the Trump administration’s “slash[ing]” of the US Agency for International Development (USAID) budget, Devex reported. The publication called the site’s restoration a “welcome development for aid agencies around the world” and noted that FEWS NET is “widely regarded as the world’s most reliable early-warning system for food insecurity”. Updated data is “expected to be available by October 2025”, said a spokesperson for FEWS NET.
Bonn to Belém
FOOD-CLIMATE NEXUS: While “agenda fights”, finance and threats to multilateralism dominated the narrative at Bonn climate talks that concluded last week, food discussions were “potentially productive”, observers told Carbon Brief. The meeting featured the first of two workshops under the Sharm-el-Sheikh joint work on climate action, agriculture and food security – the only dedicated forum for agriculture in UN climate talks. Action Aid’s Teresa Anderson told Carbon Brief: “Agriculture negotiations are now reaping the bitter harvest from Baku. After initial resistance, negotiations resulted in more targeted and potentially useful guidance to at least help identify finance gaps in agriculture.”
SECOND CHANCES: A Down to Earth comment by Indian agricultural economist Smita Sirohi described the workshop as “a “second chance to reframe the debate” around agriculture and climate to ensure more focus on adaptation, not just mitigation. While countries shared their experiences with “systemic and holistic approaches” to integrating climate into national food plans, finance for these approaches was still a sticking point. Anderson added that many governments “[came] to the conclusion that agroecology is the most effective way to achieve multiple climate and development goals”. (For more, read Carbon Brief’s in-depth summary of the meeting.)
ENDS WITHOUT MEANS: Adaptation was at the forefront in Bonn. Before the start of the conference, countries “miraculously” narrowed down a list of “indicators” for the global goal on adaptation (GGA) from 9,000 to 490. Key divisions emerged between developed and developing countries on whether to include indicators on “means of implementation” (MOI) – shorthand for finance – as well as language around “transformational” adaptation. The final text invited experts to continue refining GGA indicators to a manageable 100, it included MOI indicators that developing countries viewed as a win.
FOREST FUND: More countries and private-sector groups supported Brazil’s Tropical Forest Forever Fund during London Climate Action Week, a statement said, but there is currently no funding estimate available ahead of its launch at COP30. Brazil is aiming for “$4-5bn per year for the investment in forests, 20% of that being destined for Indigenous [peoples] and local communities”, the country’s environment and climate minister, Marina Silva, told Carbon Brief at an event last week at the Brazilian embassy in London. Silva added: “It is not donation, it is not charity…We can have a fund that will be remunerating those who protect their forests – be they communities or private owners.” Elsewhere, Brazil and the UN held the first “global ethical stocktake” in London to hear from civil society before COP30.

How extreme weather is impacting India’s ‘food in 10 minutes’ delivery drivers
This week, Cropped’s Mumbai-based reporter Aruna Chandrasekhar spoke to a union leader fighting to hold delivery-app companies accountable for protecting millions of India’s food delivery workers from extreme weather.
Driven by increasing urbanisation, smartphone usage and home-based lifestyles further entrenched by the Covid-19 pandemic, food delivery platforms continue to boom in India.
On any given waterlogged day of the week, Mumbai residents can order iPhone chargers with their okra, or apples from New Zealand, even well after midnight.
But India’s 7.7m delivery workers are having to brave extreme heat and high water in India’s crowded cities – whether on electric mopeds, cycles or horseback – to bring India such items direct to the doorstep.
It begs the question: are food delivery platforms effectively outsourcing climate adaptation to informal gig workers with fewer social protections?
A Nature Cities study published in January found a “significant surge” in lunchtime orders on the hottest days of the year in China’s cities, “reveal[ing] the transfer of heat exposure” from consumers to delivery riders.
Similarly, a study published in Sage last week found that digital technologies are “reshaping food practices in urban India in ways that reinforce existing caste, class and gender hierarchies”.
As temperatures touched 44C this summer, the Telangana state gig and platform workers union (TGPWU) urged citizens to offer a “glass of water” to the thousands of delivery workers battling extreme heat to bring them their food.
According to the International Labour Organisation, delivery workers in India can work up to 82 hours a week, with apps increasingly racing to offer consumers delivery in under 10 minutes.
“Is 10-minute delivery even possible? Can we look at humans as humans and not as robots?” says Shaik Salauddin, TGPWU founder and general secretary of the Indian Federation of App-Based Transport Workers (IFAT), speaking to Carbon Brief. He continues:
“As unions, we can tell workers to rest, but who’s going to pay for their daily bread? But if the aggregators are telling workers to carry hot parcels of biriyani in 46C, bag between their shoulders, wearing a dark uniform: can you imagine the heat and mental stress? And then buildings with 10-15 floors don’t give them access to the lift, when they have less than 10 minutes to deliver.”
Salauddin, who worked as a taxi driver for 10 years, has been fighting for the impact of extreme weather on food delivery workers to be better recognised. Two weeks ago – well into the monsoon – India’s National Disaster Management issued guidelines to recognise delivery workers “as one of the most vulnerable” to heatwaves and to create separate sections for informal workers in city and state heat action plans.
This week, Salauddin is sending out extreme rain alerts on WhatsApp and Telegram. He tells Carbon Brief that he is “tired of the PR” and “superhero” praise heaped on riders risking their lives in record floods by the same delivery platforms that offer little accountability or transparency. He says:
“I tell workers there’s a red alert for extreme rain, open drains are overflowing, your EVs won’t make it, please don’t go out there. In 10 minutes, the apps say: ‘Please come online, we’ll pay you 30% extra as part of rain mode.’ Who do I fight with now?”
To Salauddin, climate change and “just transition” are “big words” that have to be linked to livelihoods and need a far-reaching vision: whether it is subsidies for marginalised castes to buy or retrofit EVs, more charging stations, or even just restrooms for exhausted workers. Governments must engage with unions every three months, he says, not just at the height of summer or monsoon. With the exception of a few states, India’s many gig workers are not formally recognised for social security benefits.
The biggest change, Salauddin says, must come from food delivery apps themselves. He concludes:
“Simply saying that ‘we’re a broker between companies and people, we take our commission and nothing else’ is not a good model. They need to take responsibility for livelihoods, for climate impacts and their emissions. In our nature of work, we should be looking at the future of work – and the future is already here.”
News and views
COUNTING CONTROVERSY: The European climate commissioner, Wopke Hoekstra, may allow EU member states to “count controversial carbon credits from developing countries towards their climate targets”, the Guardian reported. Hoekstra told the outlet that “developing countries were keen to gain EU financing through carbon credits” and that the “possibility of allowing this was ‘potentially very attractive’”. However, the Guardian noted, “green groups are furious” and insist that the EU must “meet its targets domestically”, without the use of overseas carbon offsets.
FUELLING FOOD: Around 40% of petrochemicals are used by food systems around the world, mostly through synthetic fertilisers and plastic packaging, according to a new report. The research, from the International Panel of Experts on Sustainable Food Systems (IPES-Food), noted that food production and processing accounts for at least 15% of global fossil-fuel use. Action on food systems is “missing” from global agreements to transition away from fossil fuels, the report said. IPES-Food expert, Prof Raj Patel, said in a statement: “Delinking food from fossil fuels has never been more critical to stabilise food prices and ensure people can access food.”
PLANT FUEL: Efforts are underway in Chad to switch to “green charcoal” – a fuel made from plant waste, such as sesame stalks or palm fronds – to prevent further “rampant deforestation”, Agence France-Presse reported. The central African country has lost more than 90% of its forest cover since the 1970s and is “steadily turning to desert”, the newswire said. “Green charcoal” is intended for household uses, such as cooking, as an alternative to cut-down trees. An initiative to produce this fuel, which allegedly emits less CO2 than ordinary charcoal when burned, is backed by the World Bank and the UN refugee agency, added AFP.
G&T DANGER: “Volatile” weather, made “more likely by climate breakdown”, may impact the flavour of juniper berries – the “key botanical” in gin – according to a new study covered by the Guardian. The research, published in the Journal of the Institute of Brewing, looked at berries from seven European countries taken across different harvests. “A wet harvest year can reduce the total volatile compounds in juniper by about 12% compared to a dry year. This has direct implications for the sensory characteristics that make gin taste like gin,” the lead study author Dr Matthew Pauley, an assistant professor at Heriot-Watt University, told the newspaper.
TREE TROUBLE: The UK missed its tree-planting targets by an area of forest equivalent to the size of the Isle of Wight over the past five years, according to Carbon Brief analysis. New figures showed that 15,700 hectares of trees were planted across the UK in the last year – roughly half of the annual 30,000 hectare target set by the previous government. England, Scotland, Wales and Northern Ireland have repeatedly not met national targets since 2020, previous data showed. These missed goals amount to more than 36,000 hectares of unplanted forest.
ASIA IMPACTED: According to the World Meteorological Organisation’s State of Climate in Asia 2024 report released last week, Asia is warming twice as fast as the global average, reported the Times of India. Extreme summer heat and reduced winter snowfall “accelerated glacier mass loss” in 23 of 24 glaciers in the central Himalayas and Tian Shan, Down to Earth wrote, with drought in China affecting more than 4.8 million people. Per the report, marine heatwaves “gripped a record area of the ocean”. The north Bay of Bengal region recorded the “second fastest rate” of sea level rise globally after the South China Sea, wrote the New Indian Express.

BLEACHING POINT: Kenyan marine ecologist Dr David Obura spoke to the Guardian about coral reefs that are “flickering out across the world”.
SHADOWY BROKER: The Financial Times looked at the life and death of Samuele Landi, an Italian “telecoms entrepreneur turned fraudster” and carbon-credits broker.
HORNBILL HOUR: The Some Like it Wild Podcast spoke to Dr Aparajita Datta about her research on the “secret life” of hornbills and valuing community knowledge in conservation research.
WOMEN’S WORK: For LitHub, Dr Sarah Boon wrote about “trailblaz[ing]” women scientists who carried out fieldwork in the 1900s.
New science
- A new study in Science Advances found that more than half of existing sea turtle hotspots “may disappear by 2050, with many new habitats in high shipping intensity areas” under a high-emissions scenario. “Alarmingly”, the authors added, only 23% of these hotspots are conserved under current marine protected areas.
- According to new research in Nature Climate Change, protecting “existing young secondary forests” can remove eight times more carbon per hectare than new tree plantations.
- A new study, published in Nature and covered by Carbon Brief, found that six staple crops will face “substantial” yield losses under future climate change – even when accounting for farmers’ adaptation efforts.

Efforts to green lithium extraction face scrutiny over water use
Mining companies are showcasing new technologies which they say could extract more lithium – a key ingredient for electric vehicle (EV) batteries – from South America’s vast, dry salt flats with lower environmental impacts.
But environmentalists question whether the expensive technology is ready to be rolled out at scale, while scientists warn it could worsen the depletion of scarce freshwater resources in the region and say more research is needed.
The “lithium triangle” – an area spanning Argentina, Bolivia and Chile – holds more than half of the world’s known lithium reserves. Here, lithium is found in salty brine beneath the region’s salt flats, which are among some of the driest places on Earth.
Lithium mining in the region has soared, driven by booming demand to manufacture batteries for EVs and large-scale energy storage.
Mining companies drill into the flats and pump the mineral-rich brine to the surface, where it is left under the sun in giant evaporation pools for 18 months until the lithium is concentrated enough to be extracted.
The technique is relatively cheap but requires vast amounts of land and water. More than 90% of the brine’s original water content is lost to evaporation and freshwater is needed at different stages of the process.
One study suggested that the Atacama Salt Flat in Chile is sinking by up to 2 centimetres a year because lithium-rich brine is being pumped at a faster rate than aquifers are being recharged.
Lithium extraction in the region has led to repeated conflicts with local communities, who fear the impact of the industry on local water supplies and the region’s fragile ecosystem.
The lithium industry’s answer is direct lithium extraction (DLE), a group of technologies that selectively extracts the silvery metal from brine without the need for vast open-air evaporation ponds. DLE, it argues, can reduce both land and water use.
Direct lithium extraction investment is growing
The technology is gaining considerable attention from mining companies, investors and governments as a way to reduce the industry’s environmental impacts while recovering more lithium from brine.
DLE investment is expected to grow at twice the pace of the lithium market at large, according to research firm IDTechX.
There are around a dozen DLE projects at different stages of development across South America. The Chilean government has made it a central pillar of its latest National Lithium Strategy, mandating its use in new mining projects.
Last year, French company Eramet opened Centenario Ratones in northern Argentina, the first plant in the world to attempt to extract lithium solely using DLE.
Eramet’s lithium extraction plant is widely seen as a major test of the technology. “Everyone is on the edge of their seats to see how this progresses,” said Federico Gay, a lithium analyst at Benchmark Mineral Intelligence. “If they prove to be successful, I’m sure more capital will venture into the DLE space,” he said.
More than 70 different technologies are classified as DLE. Brine is still extracted from the salt flats but is separated from the lithium using chemical compounds or sieve-like membranes before being reinjected underground.
DLE techniques have been used commercially since 1996, but only as part of a hybrid model still involving evaporation pools. Of the four plants in production making partial use of DLE, one is in Argentina and three are in China.
Reduced environmental footprint
New-generation DLE technologies have been hailed as “potentially game-changing” for addressing some of the issues of traditional brine extraction.
“DLE could potentially have a transformative impact on lithium production,” the International Lithium Association found in a recent report on the technology.
Firstly, there is no need for evaporation pools – some of which cover an area equivalent to the size of 3,000 football pitches.
“The land impact is minimal, compared to evaporation where it’s huge,” said Gay.


The process is also significantly quicker and increases lithium recovery. Roughly half of the lithium is lost during evaporation, whereas DLE can recover more than 90% of the metal in the brine.
In addition, the brine can be reinjected into the salt flats, although this is a complicated process that needs to be carefully handled to avoid damaging their hydrological balance.
However, Gay said the commissioning of a DLE plant is currently several times more expensive than a traditional lithium brine extraction plant.
“In theory it works, but in practice we only have a few examples,” Gay said. “Most of these companies are promising to break the cost curve and ramp up indefinitely. I think in the next two years it’s time to actually fulfill some of those promises.”
Freshwater concerns
However, concerns over the use of freshwater persist.
Although DLE doesn’t require the evaporation of brine water, it often needs more freshwater to clean or cool equipment.
A 2023 study published in the journal Nature reviewed 57 articles on DLE that analysed freshwater consumption. A quarter of the articles reported significantly higher use of freshwater than conventional lithium brine mining – more than 10 times higher in some cases.
“These volumes of freshwater are not available in the vicinity of [salt flats] and would even pose problems around less-arid geothermal resources,” the study found.
The company tracking energy transition minerals back to the mines
Dan Corkran, a hydrologist at the University of Massachusetts, recently published research showing that the pumping of freshwater from the salt flats had a much higher impact on local wetland ecosystems than the pumping of salty brine. “The two cannot be considered equivalent in a water footprint calculation,” he said, explaining that doing so would “obscure the true impact” of lithium extraction.
Newer DLE processes are “claiming to require little-to-no freshwater”, he added, but the impact of these technologies is yet to be thoroughly analysed.
Dried-up rivers
Last week, Indigenous communities from across South America held a summit to discuss their concerns over ongoing lithium extraction.
The meeting, organised by the Andean Wetlands Alliance, coincided with the 14th International Lithium Seminar, which brought together industry players and politicians from Argentina and beyond.
Indigenous representatives visited the nearby Hombre Muerto Salt Flat, which has borne the brunt of nearly three decades of lithium extraction. Today, a lithium plant there uses a hybrid approach including DLE and evaporation pools.
Local people say the river “dried up” in the years after the mine opened. Corkran’s study linked a 90% reduction in wetland vegetation to the lithium’s plant freshwater extraction.
Pia Marchegiani, of Argentine environmental NGO FARN, said that while DLE is being promoted by companies as a “better” technique for extraction, freshwater use remained unclear. “There are many open questions,” she said.
AI and satellite data help researchers map world’s transition minerals rush
Stronger regulations
Analysts speaking to Climate Home News have also questioned the commercial readiness of the technology.
Eramet was forced to downgrade its production projections at its DLE plant earlier this year, blaming the late commissioning of a crucial component.
Climate Home News asked Eramet for the water footprint of its DLE plant and whether its calculations excluded brine, but it did not respond.
For Eduardo Gigante, an Argentina-based lithium consultant, DLE is a “very promising technology”. But beyond the hype, it is not yet ready for large-scale deployment, he said.
Strong regulations are needed to ensure that the environmental impact of the lithium rush is taken seriously, Gigante added.
In Argentina alone, there are currently 38 proposals for new lithium mines. At least two-thirds are expected to use DLE. “If you extract a lot of water without control, this is a problem,” said Gigante. “You need strong regulations, a strong government in order to control this.”

Maryland’s Conowingo Dam Settlement Reasserts State’s Clean Water Act Authority but Revives Dredging Debate
The new agreement commits $340 million in environmental investments tied to the Conowingo Dam’s long-term operation, setting an example of successful citizen advocacy.
Maryland this month finalized a $340 million deal with Constellation Energy to relicense the Conowingo Dam in Cecil County, ending years of litigation and regulatory uncertainty. The agreement restores the state’s authority to enforce water quality standards under the Clean Water Act and sets a possible precedent for dozens of hydroelectric relicensing cases nationwide expected in coming years.
