New data released Wednesday by a climate disclosure organisation indicates that only 41% of those reporting track value chain emissions, and significantly fewer are aware of their impact on nature.

For more than 200 years, European farmers have killed dingoes to protect livestock.

Possums on Maria Island expanded beyond usual habitat and had become ‘pretty significant predator’

The introduction of Tasmanian devils to Maria Island halved the population of brushtail possums, according to new research that suggests restoring top predators to ecosystems could help limit the number of overabundant prey.

In 2012, the carnivorous marsupials were introduced to the island off the east coast of Tasmania to create a geographically isolated insurance population free from devil facial tumour disease.

British Columbia will implement a cap on oil and gas emissions to ensure the province hits its GHG reduction target for the sector, and will also consider how credit trading may work under the system, the Canadian province announced Tuesday.

More aggressive GHG reduction targets and a simple process for California-Quebec market traders to open accounts resulted in the Washington cap-and-invest programme seeing a steep clearing price at its inaugural auction last month, an analyst said Tuesday.

Only one standards body operating in the voluntary carbon market (VCM) has a viable grievance mechanism offered to communities affected by climate projects, according to a review published Tuesday.

Carbon credit buyers have been drawn to clean cookstove projects for their extensively touted benefits in improving the health of millions of some of the world's poorest people, but observers warn that the sector bears many of the same over-crediting risks as forest protection programmes.

An academic study has claimed cookstove projects are more than six times over-credited, reigniting criticism of the voluntary carbon market that is still dousing the flames from January’s damning reports of hot air in the REDD+ avoided deforestation sector.

The collapse of the Silicon Valley Bank (SVB) could spark fresh enthusiasm for publicly-funded green banks that help propel nascent clean technology firms, with these types of set-ups continuing to evolve globally and due shortly to get a foothold in the US.

Climate change is adding energy to the atmosphere and the oceans. This in turn fuels more intense storms and heavy rainfall.

As a leader of Carbon Demand, your goal is to build the strategy and deliver monetization pathways of our solution for permanent verifiable carbon removal. Building a portfolio strategy for a variety of offtake pathways will be a critical first initiative, but developing other mechanisms to enable project finance and/or hybrid financial vehicles with partners, financial institutions and investors will also be a large part of the role.

The EU will seek guidance from its national environment ministers on the European Commission’s proposal to set up a certification framework for carbon removals, as they will convene in Brussels on Thursday.

Study shows high ozone levels make males emit fewer pheromones to attract females, which may lead to population decline

Air pollution is making it harder for fruit flies to mate because females cannot easily recognise a male’s scent, a study has found.

Female fruit flies select their mates for reproduction through the scent of their pheromones, but ozone pollution can disrupt the male’s ability to emit their characteristic odour, researchers have found. This means contaminated air can pose a threat to how successfully fruit flies and other insects reproduce, and could lead to population decline.

A new scientific approach to calculating the carbon saving of avoided deforestation projects hopes to bolster confidence in REDD+ following claims of widespread over-crediting of the voluntary carbon market sector.

The European Parliament adopted a more ambitious line on the bloc's proposed revision of Energy Performance of Buildings Directive (EPBD) on Tuesday, backing the earlier position of its industry committee (ITRE).
