Blue Cercarbono – Standard body Cercarbono published its blue carbon methodology for restoration and revegetation of coastal wetlands, it announced Monday in a LinkedIn post. CM-LUCW-001 covers reduced and removed emissions from mangroves, tidal marshes, and seagrass meadows, and shifts focus on planting-based interventions to broader ecological functions, such as rewetting and storage of soil organic carbon, the standard said. The methodology, which was published for consultation last December, is designed to support Article 6 traceability and to be compatible with Cercarbono's REDD+ framework.

Over the past week, developments across Latin America showed forest-based carbon supply being channelled into different market pathways, with countries diverging on whether credits are exported, retained for domestic compliance, or supplied to voluntary markets.

CORSIA prices ticked higher last week, reflecting the market having found a wide trading range either side of $13, and there were signs that airlines are now readying to retire for compliance.

Climate Impact X (CIX) will cease publishing price assessments for older vintage forestry and cookstove projects in the voluntary carbon market, the Singapore-based exchange said Monday. 

Swedish BECCS - Sweden-based energy firm Stockholm Exergi plans to allocate around 185k tonnes of permanent carbon removals annually from its bioenergy with carbon capture and storage (BECCS) operations to neutralise residual emissions across its value chain, according to its latest annual report. The company is also exploring CCS at its waste-to-energy plants in Hogdalen and Brista, with feasibility studies underway and potential CO2 capture starting around 2033 and 2035 respectively, with combined permanent storage of around 710k tonnes of biogenic CO2, according to the company's annual report. Stockholm Exergi targets net zero across its value chain by 2035, relying on both emissions reductions and permanent removals.

Biochar methane emissions - Flame curtain pyrolysis in kon-tiki kilns used to produce biochar emits less methane and carbon monoxide than open burning of crop residues, a study by European researchers published in GCB Bioenergy found. Methane emissions were around 2.6 grammes per kilogramme of feedstock, compared to more than 4.4 g/kg for open burning, and rose more than tenfold when moisture exceeded 25%. Higher flue gas temperatures were linked to lower methane output, while the process produced around 200 kg of biochar per tonne of straw, enabling more than 500 kg of CO2e removal when applied to soils, the analysis said.

A new soil porewater extraction technique could improve the accuracy and consistency of carbon removal estimates from enhanced rock weathering (ERW), according to a recent study.

Mazda NZ drops green claim - Mazda New Zealand has removed a claim from its website that planting five trees per vehicle would “mitigate any environmental impact from CO2 emissions” over a five-year warranty period, following a complaint filed earlier this month by Lawyers for Climate Action NZ. The Advertising Standards Authority accepted the complaint, but closed the case as settled after Mazda New Zealand withdrew the statement tied to its partnership with Trees That Count.

Japan forest deal - Japan-based automaker Suzuki Motor Corporation has signed an agreement to purchase locally generated Forest J-Credits from Tenryu Forester, marking the first issuance of such credits from Japan’s Hamamatsu region, the company said last week. The credits were created through forest management activities in the Tenryu area, historically known for timber production but facing pressure from imports and demographic decline. Suzuki said the deal supports conservation of local forests while contributing to its goal of achieving carbon neutrality across its domestic operations by FY2035, with plans to expand use of locally generated credits.

Ghana mangrove push - Ghana’s Forestry Commission and US-based developer Terraformation will collaborate to scale forest restoration projects aimed at boosting climate resilience, jobs, and local livelihoods, the organisations announced last week. The collaboration builds on a large mangrove restoration effort at Keta Lagoon in the Volta Region, where more than 3.2 mln trees have already been planted and hundreds of jobs created, many held by women. A second phase is set to launch later this year with additional planting and employment expected, while the broader programme aims to expand restoration across the country and link carbon revenues to community development, they said.

A global fast fashion retailer has received its first deliveries of permanent carbon removals (CDR) in 2025 and is preparing to source jurisdictional REDD+ (JREDD+) credits, according to its latest sustainability report.

Two tech companies and a consultancy have collectively committed to purchase over 130,000 nature-based carbon removal credits from a US-based reforestation project.

A jurisdictional REDD+ (JREDD+) programme in Colombia has completed its public consultation period, bringing it closer to issuing (Core Carbon Principles) CCP-eligible voluntary carbon credits, the project developer said last week.

US airlines could face a hefty bill for 2024 emissions under the CORSIA international aviation offsetting scheme, but it remains uncertain whether their participation will be enforced, according to a new analysis.

Integrity premiums are emerging in Australia’s carbon market, with higher-quality credits commanding sustained price differences, while project-level risks remain uneven, a recent analysis has found.

Carbon rating agencies are split on whether they fall in scope under upcoming EU rules on ESG rating activities, which could potentially help unlock more bank finance for the sector and reduce risk of integrating credits in compliance schemes, stakeholders told Carbon Pulse.

Sub-Saharan Africa saw a surge in Article 6 activity in March, with multiple countries accelerating bilateral carbon market deals and project authorisations, particularly with Switzerland.

A new guide that aims to help governments safely test emerging carbon market approaches has launched, as policymakers face growing pressure to unlock climate finance while maintaining market integrity.

Four key themes helped move agricultural soil carbon from a nascent category to the high-integrity climate solution that it is today.

A Seoul-headquartered carbon trader and project developer has appointed a new CEO, with plans to expand its presence in the international voluntary carbon market.

Blue green - Japanese developer Green Carbon has signed an MoU with Indonesian NGO PT Pesisir Indah Lestari to collaborate on mangrove restoration and emissions reduction projects. The partnership will assess at least 1,000 ha for restoration, estimate blue carbon stocks, and project sequestration over up to 35 years. The five-year agreement will also emphasise local community engagement and sustainable development alongside biodiversity protection, the companies said.

Port credits - The VOC Port Authority in India’s Tamil Nadu has began generating carbon credits from its renewable energy portfolio, targeting revenue of around $5.3 mln through the monetisation of emissions reductions, it has announced. One of India’s 13 major ports and an important gateway for the nation’s southern region, it plans to generate carbon credits by adopting sustainable practices such as renewable energy use, energy efficiency measures, and reduced fossil fuel consumption across its operations. The port has registered five renewable projects under for the generation of carbon credits, with a collective installed capacity of 12.4 MW, it said.

Zefiro Methane Corp. and its founder have declared separate victories in their high-stakes legal battle for control of the offset project developer.
