New study published in Cell Reports Sustainability finds emission reductions provided $249bn of climate and health benefits

By increasing its use of renewable energy, the US has not only slashed its planet-warming emissions but also improved its air quality, yielding hundreds of billions of dollars of benefits, a new report has found.

The study, published in Cell Reports Sustainability on Wednesday and based on publicly available data, focuses on uptick of renewable energy in the US from 2019 to 2022.

Officials are now incentivizing testing, but experts say workers need protective equipment and paid sick leave to prevent further spread

On a US dairy farm, working in the milking parlor can mean seven-day weeks, 12-hour shifts and intimate contact with cows and everything they expel.

“When you disconnect the machine from the udder, it can shoot milk in your face,” said José Martínez, a former dairy worker and United Farm Workers advocate based in Washington state. “And there’s no time or place to eat. So we ate our tacos in spare moments with cow shit on our hands.”

Widening government-run scheme would counter mistrust among householders, says consumer group

The next government should force all tradespeople who install home heat pumps, solar panels and insulation to sign up to a mandatory accreditation scheme to counter mistrust in the industry, a leading consumer group is demanding.

A report from Which? found that households face “significant anxiety” in choosing tradespeople to fit low-carbon heating systems, such as heat pumps, and insulation after “press stories about poor work and rogue traders”.

The NSW government is “very concerned” that asbestos has been found in landscaping soil bought in Sydney, the environment minister has said.

A Guardian Australia investigation revealed this week that contaminated soil fill products were on sale at landscape and garden stores, a decade after NSW Environment Protection Authority (EPA) investigators first raised concerns about potential contamination.

US agency found PFOS and other types of PFAS in pesticides but failed to disclose those results, watchdog group alleges

Documents obtained from the US Environmental Protection Agency (EPA) indicate the agency may have presented false information to the public about testing for harmful contaminants in pesticides, according to allegations being made by a watchdog group and a former EPA research fellow.

The claims come almost a year to the day after the EPA issued a May 2023 press release that stated the agency found no per- and polyfluoroalkyl substances (PFAS) in testing of samples of certain insecticide products. The press release contradicted a published study by the former EPA researcher that had reported finding PFAS in the same pesticide products.

Labour and Liberal Democrats dominated list of MPs who were rated as very good in backing environmental policies

No elected Tory MPs have been rated as voting positively on climate issues, under a survey of parliamentary voting patterns since the Conservatives took power in 2010.

Only a single sitting Conservative was rated as “good” on climate votes in the ranking, but that was Lisa Cameron, the MP for East Kilbride, who defected from the Scottish National Party in October.

One in 10 fillets of shark meat bought by Australians at fish and chip shops and markets – often labelled as flake – is from a threatened species, according to a study that has uncovered widespread mislabelling of shark sold to the public.

Nine of 91 fillets were found to be either scalloped hammerhead, greeneye spurdog or school shark – all considered threatened in Australia – after scientists at Macquarie University used DNA analysis to check what they were sold.

Exclusive: Facilities owned by Bingo Industries and Aussie Skips Recycling among more than 20 named in NSW parliament for breaching regulations

• Recycling fill sold in Sydney stores tests positive for asbestos

Some of the best-known waste companies in New South Wales are among those that broke safety rules that led to potentially contaminated soil fill being supplied to backyard landscapers, schools, childcare centres and parks across the state.

As part of an investigation into soil contamination, Guardian Australia can reveal that Bingo Industries, Aussie Skips Recycling, Benedict Recycling and KLF Holdings breached state regulations for testing a type of cheap soil made from recycled construction and demolition waste.

Companies found in the 2019 investigation to have asked private laboratories to keep retesting samples when they exceeded contaminant thresholds were: Bingo Industries in Auburn, four Benedict Recycling facilities in Sydney, Breen Resources in Kurnell, South Coast Equipment Recycling at Warrawong, Hi-Quality Waste Management at St Marys and Brandown Pty Ltd at Cecil Park. The 2013 investigation also found two Benedict Recycling facilities were retesting samples.

Twenty-one facilities were found in the 2019 investigation not to have been meeting EPA sampling rules such as the frequency with which samples should be collected and tested and what they were tested for: eight sites owned by Bingo Industries, four owned by Benedict Industries and one each by Aussie Skips Recycling, KLF Holdings, Breen Resources, Brandown, Hi-Quality Waste Management, Budget Waste Recycling, Rock & Dirt Recycling, South Coast Equipment Recycling and Builders Recycling Operations. Aussie Skips Recycling and Hi-Quality Waste Management were also among 11 facilities found in 2013 to be breaching testing rules.

Following the 2019 investigation, the EPA issued prevention notices to six facilities after it detected asbestos in their recovered fines. In at least two instances the product had already been removed for use in the community.

In one case identified in the 2019 EPA investigation, 16 tonnes of asbestos-contaminated soil produced by KLF Holdings was supplied to an apartment complex in Bankstown, and the regulator was forced to order a clean-up.

The Coalition has no climate policy. But Labor’s positions are undermined by its confused stance on gas and the delay of new environmental laws

Federal parliament is back for the next fortnight and I have a wishlist. Not for things that will happen – let’s not get ahead of ourselves – but for questions that could be addressed if the country is to treat the climate and extinction crises as seriously as our leaders claim they do.

There is no shortage of discussion about nuclear energy due to the Coalition’s much-hyped but yet-to-appear plan to overturn a national ban and bring it to Australia. The issue won plenty of attention after a CSIRO-led assessment that it would be far, far more expensive than wind and solar backed by energy storage and new transmission lines.

Reduce emissions, build resilience, repair ecosystems, remove greenhouse gases: these are the four Rs that can save us

• David King is chair of the global Climate Crisis Advisory Group

In 2008, the late American climate scientist Wally Broecker warned of the global repercussions of polar ice loss. Today, his predictions echo louder than ever as Greenland ice haemorrhages at an alarming rate, threatening rapid sea-level rise. Over the past 15 years, the Arctic Circle region has been heating up at four times the global average; it’s now more than 3C above levels in the 1980s. In 2023, we witnessed a staggering loss of Antarctic Sea ice.

Over the past year, land and ocean temperatures have soared, far beyond what was anticipated for an El Niño year. Global average temperatures have breached the 1.5C mark, indicating that climate transition has been unleashed. From record-breaking wildfires across continents to catastrophic floods threatening to submerge major cities, extreme climate events have become the new norm, causing massive loss of life and economic damage worldwide.

Studies find red, blue and green plastic decomposes into microplastic particles faster than plainer colours

Retailers are being urged to stop making everyday products such as drinks bottles, outdoor furniture and toys out of brightly coloured plastic after researchers found it degrades into microplastics faster than plainer colours.

Red, blue and green plastic became “very brittle and fragmented”, while black, white and silver samples were “largely unaffected” over a three-year period, according to the findings of the University of Leicester-led project.

Asbestos has been found in recycled soil fill for sale in New South Wales landscape and garden stores, more than a decade after investigators first raised concerns about contamination.

Guardian Australia bought four products at Sydney landscape supply shops and had samples analysed by accredited private laboratories.

Cut free from the constraints of reporting, a story can take its own shape, can lead you down rabbit holes you’d never expected

During my nearly 40 years as a journalist, the climate crisis has been a constant, creeping refrain – from the first greenhouse conference in the late 1980s and the first IPCC report in the early 90s. There was the Hawke governments’ plan to cut emissions by 20% below 1988 levels by 2005, and the subsequent walking back of that plan.

Then on through the decades of bitter political division and debate and policy failures; the proposal for an Emissions Trading Scheme under John Howard; Kevin Rudd’s “great moral challenge of our generation”; the ill-fated Carbon Pollution Reduction Scheme, the Gillard ETS, the relentless campaign against it by Tony Abbott and the wasted decade of what’s become known as the “Climate Wars” that followed.

“Energy efficient”, “carbon neutral” and “net zero” are buzzwords we hear more and more as we face the impact of climate change. But do we think about them enough in building?

Globally, a move towards sustainable housing is growing. In Europe, efforts to move to greener homes hope to combat rising energy costs and be better for the planet. But 40% of global carbon dioxide emissions still come from the real estate sector.

Thousands of children could die after court backs campaign group over GM crop in Philippines, scientists warn

Scientists have warned that a court decision to block the growing of the genetically modified (GM) crop golden rice in the Philippines could have catastrophic consequences. Tens of thousands of children could die in the wake of the ruling, they argue.

The Philippines had become the first country – in 2021 – to approve the commercial cultivation of golden rice, which was developed to combat vitamin-A deficiency, a major cause of disability and death among children in many parts of the world.

Exclusive: after cryptosporidium outbreak in Devon, residents in south-east London report stomach cramps and diarrhoea

Thames Water has sent samples of water for lab testing after dozens of people reported becoming unwell with stomach cramps, vomiting and diarrhoea in south-east London.

Earlier this month, unsafe drinking water led to more than 100 cases of a waterborne disease in Devon, with people asked to boil their water because of contamination fears.

Small islands like ours face an uncertain future. We can adapt – but climate finance that we badly need must be unlocked

• Mohamed Muizzu is the president of the Maldives

For the Maldives, the existential threat of the climate crisis, particularly sea level rise, has been a reality we have grappled with for decades. In 1989, recognising the urgency of our situation, with our islands standing just one metre above sea level, we brought this issue to the global stage for the first time.

This early recognition of our vulnerability sparked a national transformation as we embarked on proactive climate resilience and adaptation measures. Thirty-five years later, has the rest of the world truly been listening? If you look at how the world’s reaction to the climate crisis is funded, the answer is clearly “no”.
