A commerce platform heavily involved in engineered carbon dioxide removal (CDR) agreements said few new corporate buyers have emerged to provide the necessary financing to help scale up nascent technologies, according to a recent report.

The granting of Unesco world heritage site status would give these habitats the recognition they deserve

In the 17th century, when the first large-scale attempts were being made to drain the Fens, an anonymous protest ballad imagined the creaturely resentment coursing through the waters of the wetlands. “For they do mean all Fens to drain, and waters overmaster,” laments a sea lamprey in Powte’s Complaint. “All will be dry, and we must die, ’cause Essex calves want pasture”.

The local protests were in vain. Since 1700, according to research published this year, the UK has lost more than 75% of its wetlands as land has been drained for development and farming. The Industrial Revolution inevitably accelerated the destruction of terrain that was viewed simply as wasteland. But the tide may finally be turning for habitats that should be valued as 21st century environmental assets, crucial both to preserving biodiversity and protecting Britain’s coastline.

No single alternative fuel is emerging as the frontrunner for the shipping sector’s decarbonisation, a number of key figures of the Belgian shipping industry agreed at an event dedicated to decarbonising the industry on Tuesday.

Scientists operating a submersible have discovered deep-sea coral reefs in pristine condition in a previously unexplored part of the Galapagos marine reserve. Diving to depths of 600 metres (1,970ft), to the summit of a previously unmapped seamount in the central part of the archipelago, the scientists witnessed a breathtaking mix of deep marine life. This has raised hopes that healthy reefs can still thrive at a time when coral is in crisis due to record sea surface temperatures and ocean acidification

Reusables have 25% less global heating potential, finds UK government report, but overall picture is mixed

Environmental campaigners are calling on the UK government to take action after new analysis found a significant difference between the carbon footprints of washable and disposable nappies.

Reusable nappies have 25% less global heating potential compared with single-use nappies, according to a report commissioned by the Department for Environment, Food and Rural Affairs (Defra).

A record number of companies adopted net zero targets in the first quarter of this year while and retirement levels of offsets held steady to dispel concerns of a long term crisis in the voluntary carbon market, a webinar heard Tuesday.

An initiative led by European investors released on Tuesday a net zero standard for the big-emitting oil and gas sector, looking to navigate the murky waters of net zero pledges and drive climate change progress through capital allocation. 

Free carbon allowance handouts in the EU should be based on the products rather than the process of making them as is currently the case, a think-tank has recommended, as Brussels prepares to make amendments to rules governing its free allocation of EUAs.

Report highlights environmental and economic impacts of algae threatened by climate crisis, overfishing and pollution

Almost a third of the globe’s coastal environments rely on kelp to reduce local pollution and sustain fisheries that provide billions of dollars in benefits, according to a new study.

But the climate crisis, overfishing, invasions of voracious sea urchins and pollution are putting at risk the world’s kelp forests, threatening the economic benefits they provide and the huge array of species they support.

Biodiversity credits are one of the key vehicles for financial institutions to channel capital into nature protection and restoration, according to a UNEP report published this month that noted how investors represent a vital source of funding to meet the goals of the Global Biodiversity Framework (GBF).

London-listed Serabi Gold extracting gold without approval of Brazilian land registry and Indigenous communities

A London-listed company has been mining gold in the Amazon rainforest without approval from the Brazilian land agency or the consent of nearby Indigenous communities, according to an investigation by the Guardian and partners.

Serabi Gold has been blasting 4.5 metre-wide tunnels and trucking ore from the Coringa project site in Pará state. But interviews with land agency officials and documents seen by the Guardian, Unearthed and Sumaúma indicate that ownership of the area is disputed and the land was allegedly occupied by illegal land-grabbers.

Officials announce 45-day ban on harvesting elvers in provinces of Nova Scotia and New Brunswick

Canada has temporarily shut down its baby eel fishery following a string of attacks on harvesters, as well as mounting concerns over widespread poaching of the threatened fish.

Officials from the department of fisheries and oceans on Saturday announced a 45-day ban on harvesting the young eels, called elvers, in the provinces of Nova Scotia and New Brunswick, shuttering the lucrative C$50m (£30m) market.

A new technology resembling a waterborne drone aims to independently collect environmental DNA (eDNA) from the world’s oceans, providing scientists and other stakeholders with the data they need to track and manage local biodiversity at scale.

Researchers have developed an innovative method to remove CO2 from the atmosphere while mining critical metals for renewable energy infrastructure.

Diving to 600m, researchers find reefs full of octopus, lobster and fish, raising hopes for corals’ survival amid rising sea temperatures

Scientists operating a submersible have discovered deep-sea coral reefs in pristine condition in a previously unexplored part of the Galápagos marine reserve.

Diving to depths of 600 metres (1,970ft), to the summit of a previously unmapped seamount in the central part of the archipelago, the scientists witnessed a breathtaking mix of deep marine life. This has raised hopes that healthy reefs can still thrive at a time when coral is in crisis due to record sea surface temperatures and ocean acidification. It also showed the effectiveness of conservation actions and effective management, they said.

European carbon prices posted robust gains on Tuesday amid largely technically-driven trading, while lawmakers in the European Parliament approved a raft of changes to the market under the Fit for 55 programme.

European lawmakers on Tuesday gave their approval to a series of provisional deals aiming to put shipping, buildings and road transport under carbon pricing, impose a carbon border adjustment mechanism (CBAM), and launch a Social Climate Fund.
