Researchers predict energy use for air conditioners and refrigeration to jump 90% on 2017 levels

A burgeoning middle class and a warming world will result in energy demand for cooling overtaking that for heating by the middle of the century, researchers have predicted.

Energy use for air conditioning, refrigeration and other cooling appliances will jump 90% on 2017 levels, experts estimated, posing a challenge for energy grids and efforts to curb climate change.

The government pledged in 2016 to enshrine a zero target in law to meet its Paris commitments, but has yet to pass any legislation

The UK is to review its long-term target to cut climate emissions as part of global efforts to curb rising temperatures, the government has announced.

The announcement by clean growth minister Claire Perry during the Commonwealth heads of government meeting (Chogm) raises the possibility the UK could implement a target to reduce emissions to “net zero” by 2050, tightening the existing goal to cut greenhouse gases by 80% by that date.

Judge dismisses claims by Polish government that logging was necessary to protect ancient forest from outbreak of bark beetles

The EU’s highest court has ruled that Poland’s logging in the Unesco-protected Białowieża forest is illegal, potentially opening the door to multi-million euro fines.

At least 10,000 trees are thought to have been felled in Białowieża, one of Europe’s last parcels of primeval woodland, since the Polish environment minister, Jan Szyzko tripled logging limits there in 2016.

The UK’s climate laws forged a path for others to follow. But as progressive nations commit to zero emissions, it must reclaim its leading role, writes Sweden’s deputy prime minister

What does it mean for a nation to be a “climate leader” in 2018?

At the very least, it must mean having a firm plan in place to deliver your nation’s fair share of the Paris agreement. During that stunning fortnight in December 2015, 195 governments freely and willingly committed not only to keep global warming well below 2C, but to aim for the safer level of 1.5C. And they committed to bring net greenhouse gas emissions down to zero.

Firm struggles to hit targets for mass-market electric car after reeling from excessive automation and mounting pressure

Tesla has temporarily suspended its Model 3 assembly line as Elon Musk’s electric car firm struggles to deliver on targets.

The company said the move was a planned production pause of up to five days. It is the second time since February that Tesla has halted its production line for the Model 3 at its Fremont, California plant.

Poorest are hardest hit with many developing countries falling behind on cleaning up toxic air pollution

More than 95% of the world’s population breathe unsafe air and the burden is falling hardest on the poorest communities, with the gap between the most polluted and least polluted countries rising rapidly, a comprehensive study of global air pollution has found.

Cities are home to an increasing majority of the world’s people, exposing billions to unsafe air, particularly in developing countries, but in rural areas the risk of indoor air pollution is often caused by burning solid fuels. One in three people worldwide faces the double whammy of unsafe air both indoors and out.

The scale of growth of Australia’s natural gas industry is inconsistent with our Paris commitments

Australia is currently aggressively developing its natural gas resource. By the end of 2018, it is likely to overtake Qatar as the world’s largest liquified natural gas (LNG) exporter.

Western Australia is leading the way on developing gas with the premier, Mark McGowan, calling for the state to be a global LNG hub. Recently businessman Andrew Forrest announced a radical plan to create a “virtual gas pipeline” linking WA gas to the east while Chevron over the weekend committed to the second stage of its multi-billion dollar Gorgon project expansion.

First exploration fracking expected next year but national parks and conservation areas will be protected

The Northern Territory government has lifted a ban on hydraulic fracturing of onshore gas that will open up more than half of the territory’s land mass to the controversial practice.

The first exploration fracking by petroleum companies is expected to occur early next year after the implementation of a regulatory regime and new laws, which the government insists will be strict.

Most people willing to swap to supermarkets trying to improve farming standards, survey finds

Shoppers around the world overwhelmingly support high animal welfare standards for pigs, and most would also be prepared to change their supermarket habits in response, an international survey on pork consumption has found.

Seven out of 10 people questioned said they found the manner in which pigs are reared for slaughter on some factory farms “upsetting”, “wrong” or “shocking”, after being shown photographs of some pig-keeping conditions in the online poll. The survey highlighted practices such as sows kept in small cages, antibiotic use, as well as tail-docking, teeth-grinding and castration, sometimes without pain relief.

The breakthrough, spurred by the discovery of plastic-eating bugs at a Japanese dump, could help solve the global plastic pollution crisis

Scientists have created a mutant enzyme that breaks down plastic drinks bottles – by accident. The breakthrough could help solve the global plastic pollution crisis by enabling for the first time the full recycling of bottles.

The new research was spurred by the discovery in 2016 of the first bacterium that had naturally evolved to eat plastic, at a waste dump in Japan. Scientists have now revealed the detailed structure of the crucial enzyme produced by the bug.

Justin Trudeau is bailing out a Texas oil billionaire. He should be bailing out Canada’s workers and the climate.

Last Saturday, Indigenous leaders stood arm-in-arm in front of the gates of Kinder Morgan’s pipeline worksite in Burnaby, British Columbia.

For weeks before, hundreds of non-native people – environmentalists, federal parliamentarians Elizabeth May and Kennedy Stewart, even an engineer formerly employed by the Texas oil corporation – had marched to the same place. In each case, police approached, read aloud their violation of a no-go zone, and arrested and shackled them.

Purchase of a soundproof booth for EPA chief violates federal law that prohibits spending more than $5,000 on office improvements

An internal government watchdog says the Environmental Protection Agency violated federal spending laws when purchasing a $43,000 soundproof privacy booth for administrator Scott Pruitt to make private phone calls in his office.

The Government Accountability Office issued its findings on Monday in a letter to Senate Democrats who had requested a review of Pruitt’s spending.

With Australia’s beaches and oceans covered in rubbish, Tangaroa Blue volunteers spend days trying to clean things up. While these images are not beautiful or professionally taken, they are the harsh reality of the world’s plastic pollution problem.

PM says he is prepared to use taxpayer dollars to fund controversial expansion opponents say will have serious environmental consequences

Justin Trudeau has said Canada’s government is prepared to use taxpayer dollars to push forward plans for a controversial pipeline expansion, despite protests and efforts by a provincial government to halt the project on environmental grounds.

Biodiversity concerns prompt emergency plan to use ferrets to round up the few rabbits left

It is not a pastime for which rabbits usually require much encouragement. But a mystery depletion in numbers on the Dutch island of Schiermonnikoog has led to an emergency effort to coax the local population into breeding … well, like rabbits.

Ferrets are being deployed to chase the reluctant remaining animals out of their warrens and into the hands of conservationists, who are bringing them together, safe from the stress of predators, in the hope that romance will blossom.

Environmentalists call strategy ‘20th century response to a 21st century problem’

Environmental leaders have dismissed BP’s new low-carbon strategy as “greenwash” and a lightweight response to climate change and the energy market’s rapid switch to renewables.

In a strategy published on Monday, BP said there would be no increase in its carbon footprint over the next seven years because it will cut emissions from its oil and gas rigs, and offset the rest.
