California Carbon Allowance (CCA) prices climbed this week on very thin volume in a holiday-shortened period, while Washington Carbon Allowance (WCA) values remained relatively flat as consignment permits were announced for the Q3 auction.

WCI compliance offset demand will accelerate in 2023 amid higher emissions and alongside a significant increase in voluntary market interest, as credit supply will pick up pace next year ahead of the linked cap-and-trade programme's full compliance deadline and as usage quotas are expanded in the California's subsequent true-up period, an advisory firm said in a report published Thursday.

New York regulators should abandon a price ceiling in crafting their economy-wide cap-and-invest rule, while also implementing a consignment requirement for all freely distributed permits, programme advocates said Thursday.

The EU will require several forms of finance to achieve its 2030 carbon removals target but there is potential for the ETS price alone to be sufficient to scale the sector after 2030, a conference heard on Thursday.

Negotiators at the UN’s International Maritime Organisation are honing in on a revised emissions strategy for shipping, with officials finalising draft text on Thursday that is more ambitious than the IMO's 2018 version but still adrift from aligning the sector with Paris Agreement climate objectives.

The Smithsonian Tropical Research Institute (STRI) has received a $12 million grant from the Bezos Earth Fund to support an international system to independently ensure the accuracy of satellite monitoring of forest biomass.

Zambia is following in the footsteps of other African nations and will regulate its carbon market and take a share of revenues.

Next generation cells surpass limits of today’s cells and will accelerate rollout of cheaper, more efficient solar power

Solar power cells have raced past the key milestone of 30% energy efficiency, after innovations by multiple research groups around the world. The feat makes this a “revolutionary” year, according to one expert, and could accelerate the rollout of solar power.

Today’s solar panels use silicon-based cells but are rapidly approaching their maximum conversion of sunlight to electricity of 29%. At the same time, the installation rate of solar power needs to increase tenfold in order to tackle the climate crisis, according to scientists.

World Athletics president says climate crisis and poor air quality may cause havoc to the sporting calendar

London will not be considered as a host for large sporting events such as the World Athletics Championships because of its poor air quality, Sebastian Coe has warned.

The World Athletics president and two-time Olympic gold medallist, who led the capital’s successful bid for the 2012 Games, added that rising temperatures would force sports bodies to change their calendar of events.

Carbon credit certifier Gold Standard has released a new methodology for projects that reduce methane emissions from rice cultivation, five months after a popular UN protocol was embroiled in controversy.

The country generates more solar energy than all other countries combined, but burns half the planet’s coal. There are lessons here for the rest of us, though

Big numbers are a hallmark of China’s economy and now its energy transition: they thrill, they mystify, and at times they contradict, at least on the surface.

China’s solar capacity is now 228 gigawatts (GW), more than the rest of the world combined, according to Global Energy Monitor. And wind capacity, at a whopping 310GW, also leads the world. With another 750GW of new wind and solar projects in the pipeline, China will hit its 2030 target of 1,200GW – an unimaginable number when proposed just a few years ago – five years early.
