Carbon removal (CDR) projects may not directly remove CO2 from the atmosphere and could be embedded within systems that add more emissions on a net basis, prompting experts to suggest a new set of questions to help guide industry investment.

Tree-planting is the most cost-effective form of carbon removals, as long as climate and economic risks are considered, concluded a new study.

A US environmental group is suing the state of Louisiana over a proposed CO2 pipeline project that would cut through a protected wildlife area along the Gulf Coast.

Gasps from dockside crowd watching Bigg’s orca pod in event described as ‘once-in-a-lifetime experience’

A pod of orcas swam close to shore and amazed onlookers in Seattle by treating the whale watchers to the rare sight of the apex predators hunting a bird.

The pod of Bigg’s killer whales visited Elliott Bay and were seemingly on a hunt underwater just off Seattle’s maritime industrial docks. The pod exited the bay close to the West Seattle neighborhood across from downtown, where people were waiting to catch sight of them.

Uncertainty over climate and economy means ‘investment portfolio’ approach needed, researchers say

An “investment portfolio approach” needs to be applied to large-scale tree planting across the world to reduce the risks of the wrong species being planted in the wrong place, economists have said.

Countries have made ambitious pledges to plant billions of trees to remove greenhouse gases and tackle global heating. The UK has committed to plant 30,000 hectares (74,000 acres) of trees each year by 2025 and maintain the rate until 2050, the European Commission has pledged to plant 3bn trees across member states by 2030, and the US under the previous administration committed to planting 1bn trees by the same date.

European carmakers are to be given two extra years to meet this year’s pollution target, the European Commission president, Ursula von der Leyen, has said, in a further rollback of her green deal climate policies.

Companies who sell too many dirty vehicles this year will be allowed to compensate by selling more clean vehicles in the two years that follow, under a proposal that would stretch the window of compliance for the 2025 fleet emissions target to 2027.
