Environmental organisations are calling for RGGI member states to significantly increase the ambition of the scheme’s allowance budget, along with other mechanisms to improve the CO2 mitigation performance of the Northeast and Mid-Atlantic US carbon market, according to public comments.

California Carbon Allowance (CCA) prices this week made up all of their losses after a massive sell-off as traders pointed to speculative interest and options positions as drivers, while RGGI Allowance (RGA) values soared to a new all-time high before plunging after Virginia’s governor-elect announced he intends to pull the state out of the market next year.

French President Emmanuel Macron said on Thursday he will seek adoption of the EU's proposed carbon border adjustment mechanism (CBAM) by the middle of next year, a clear signal that the proposal will be a priority for Paris within the wider climate agenda.

Members of the governance body tasked with taking forward the work of the private sector Taskforce on Scaling Voluntary Carbon Markets said they will call out project developers, intermediaries, and other market actors that put profits before the climate.

Study finds natural regrowth yields better results than human plantings and offers hope for climate recovery

Tropical forests can bounce back with surprising rapidity, a new study published today suggests.

An international group of researchers has found that tropical forests have the potential to almost fully regrow if they are left untouched by humans for about 20 years. This is due to a multidimensional mechanism whereby old forest flora and fauna help a new generation of forest grow – a natural process known as “secondary succession”.

The hubbub of an Indonesian reef should comes as no surprise: the world below is alive with sound

A coral reef in Indonesia thought to be dead has been discovered to be erupting with glorious uproar – the sound of fishes whooping and grunting as they communicate and search for food. It’s like Finding Nemo come to life. We shouldn’t be surprised. The ocean, like Prospero’s island in The Tempest, is full of strange noises. It crackles and it roars. Jacques Cousteau may have been a great ocean explorer, but when he made his film The Silent World in 1956, I wonder whether he was actually listening down there, through the bubbles of his aqualung.

Sound travels five times faster in the water. The ocean is a giant conductor of sound, an aquatic internet for every organism in it. They feel it in their bodies, and as they create sound, they are physically reaching out: from pistol shrimps that snap their claws so loudly that the sound makes them seem a hundred times bigger, to the great whales who, as Roger Payne, the first person to record and release whale song, has observed, make a sound as big as the ocean itself, and which can be heard for thousands of miles. A humpback in the Caribbean can be heard by a fellow whale off the coast of Europe. At 230 decibels (an aeroplane 100 feet away reaches 140dB), sperm whales are the loudest animals on Earth. Diving with these cetaceans in three-mile-deep waters off the Azores, I had to sign a consent form from the islands’ government, waiving liability should my hearing be damaged. Indeed, when I was first echo-located by a large female sperm whale, I felt her sonar clicks judder through my body like an MRI scanner.

The Polish parliament passed on Thursday a resolution calling on EU member states to suspend the EU ETS and to reform the bloc’s carbon market, according to media reports.

Scientists hope the hi-tech sleeping bag will stop eyeballs being squashed by zero-gravity in space.

The loss of marshes, bogs and swamps is driving a global decline in dragonflies, conservation research finds.

New procedures to calculate the allocation of free EUAs to industry may lead to delays in handing out allowances each year, putting at risk a trading strategy that has allowed industrial companies to raise cash during economic downturns, analysts say.

New research sees two-thirds of mollusc types only found living by hydrothermal vents added to IUCN’s red list of endangered species

Almost two-thirds of the hundreds of mollusc species that live in the deep sea are at risk of extinction, according to a new study that rings another alarm bell over the impact on biodiversity of mining the seabed.

The research, led from Queen’s University in Belfast, has led to 184 mollusc species living around hydrothermal vents being added to the global red list of threatened species, compiled by the International Union for the Conservation of Nature (IUCN). While researchers only studied molluscs that were endemic to the vents (hot springs on the ocean floor), they said they would expect similar extinction risks for crustaceans or any other species reliant on the vents.

Project backed by Boris Johnson likely to get go-ahead but is on site that rare birds travel though, campaigners say

A major new windfarm project that will power millions of homes is likely to be approved on Friday, but conservationists fear for the safety of endangered birds in the area.

The Norfolk Boreas offshore windfarm is due to get the green light from the government, the Guardian can reveal.

More than 20 per cent of solar output could be curtailed in a future grid, because oversizing solar would be cheaper than storage. But that doesn't count in hydrogen demand.

An Estonia-based blockchain company has developed a platform to track offsetting of emissions from LNG shipments and allow several parties to contribute carbon credits to the same cargo, in a bid to boost transparency around controversial ‘carbon neutral’ fossil fuel announcements.

This role will be focused on voluntary carbon offtake transactions, carbon neutral commodity transactions and other structured carbon-related transactions.
