Carbon accounting firm Absolute Climate has opened a month-long public consultation on an updated version of its Absolute Carbon Standard (ACS), introducing revisions to its framework for certifying removal activities and low-carbon products amid growing scrutiny of market integrity.

Brussels must strike a balance between scale and integrity when it designs its international carbon credit purchasing framework, market stakeholders said this week, as the Commission digests the results of its recent consultation on the matter.

Seaweed credits - Carbonwave expects to be issued its first sargassum carbon credit vintages in 2027, following the advancing of a methodology under Gold Standard and ongoing project-specific verification activities, it said in an annual report released in June. The anticipated issuance would represent a significant milestone for both the company and the wider blue carbon market, the developer claimed. If successful, these credits are expected to be among the first commercially issued carbon credits linked to methane emissions avoidance from sargassum seaweed. Carbonwave said it believes the development could help demonstrate the viability of innovative ocean-based climate solutions and contribute to the growth of blue carbon markets by creating a new pathway for verified emissions reductions.

A Swiss climate organisation reported lower income and lower spending on climate protection projects in 2025, while its initiatives generated 2.93 million tonnes in certified CO2 emission reductions.

The European Commission needs to confirm it will bring carbon removals (CDR) into the EU ETS when it proposes market reforms next month – providing a much-needed policy push to a global public good, a former UK government official has said.

An environmental watchdog publication alleges that carbon credits from Senegal’s flagship mangrove restoration project were overstated, with researchers describing much of the claimed storage as “ghost carbon”.

The European Commission is developing a new blue carbon credit certification system that aims to reward the expansion and creation of marine ecosystems for their role in absorbing CO2, a senior official said, while presenting the EU’s new island and coastal strategy.

A UK-based voluntary carbon offset provider will buy nature-based removals from an afforestation, reforestation, and revegetation (ARR) project under a "staggered spot" agreement covering both issued and in-verification credits, it announced on Thursday.

Recently published research shows how estimates of leakage for forest carbon projects can be significantly improved, which is necessary for addressing an important integrity issue and building confidence in carbon markets as a tool for climate action.

The Science Based Targets initiative (SBTi) has published its long-awaited Corporate Net-Zero Standard Version 2.0, which recognises companies that address their ongoing climate impact, including through the additional buying of high-quality reduction or removal credits, and plans to mandate such action from 2035, but stops short of permitting any offsetting to account for in-chain emissions.

India's carbon credit startup ecosystem remains dwarfed by other climate technology sectors, attracting just a fraction of the investment flowing into electric vehicles, renewable energy, and battery storage, new data showed.

First issued credits - China's Guangzhou has successfully issued the first batch of carbon credits from a mangrove project, developed based on a local methodology, Guangzhou Daily reported. A total of 1,251 credits were issued, including 554 from mangrove afforestation and 697  from restoration initiatives in Nansha Wetland. This issuance follows the city's release of a methodology last year to quantify local mangrove carbon sequestration.  

A member of the international Greenhouse Gas Protocol’s Independent Standards Board tendered their resignation earlier this week based on deliberations over forest carbon accounting.
