Methane milestone - Calgary-based oilfield services company Kathairos announced Monday it has eliminate 1 MtCO2e to-date via the application of its nitrogen systems to oil and gas operations to reduce methane output. Currently, the company's technology is eliminating more than 1,250 tCO2e daily through its 3,000 liquid nitrogen systems deployed across over 70 facilities across North America. According to Kathairos, the advantage of its technology is its simplicity, which it said requires no external power, no moving parts, and no disruption to existing operations, but through which nitrogen simply power devices previously actuated by natural gas.

Global wildfire activity in 2025 produced the second-lowest burned area and third-lowest CO2 emissions since satellite records began in 2002, but a growing concentration of destructive fires in populated and carbon-rich regions continued to generate severe human and economic impacts, according to a review published this week.

CORSIA prices failed to rebound last week, with price assessments for eligible units down by more than 12% week-on-week and benchmark ICE futures dipping below $10/tonne amid higher jet fuel prices, even as market executives expressed hope for resurgence in demand once the Middle East conflict ends.

European Commission officials have detailed a seven-step process for carbon registries to obtain recognition under the EU’s Carbon Removals and Carbon Farming (CRCF) regulation, saying the procedure will typically take about six months.

A Thai state agency and an agribusiness and food conglomerate announed last week they have launched a rubber plantation project that aims to generate up to 1 million carbon credits across 80,000 hectares in northeastern Thailand.

Runway ready – Russia’s application for accreditation under CORSIA has entered the final stage of review by ICAO, with a decision expected in August, according to the country’s economic development minister. Interfax reported last week that Maxim Reshetnikov said Russia’s application had successfully passed all previous assessment stages and described it as “fairly strong”, adding that any negative outcome could result in a request for revisions rather than outright rejection. Accreditation could provide a boost to Russia’s voluntary carbon market by allowing airlines to use domestically issued carbon credits for future CORSIA compliance, observers said.

Denmark deal – Danish financial institution Nykredit has entered a four-year partnership with carbon removals platform Klimate to purchase CDR credits and support the development of carbon capture and storage technologies in Denmark, it was announced last week. The agreement will help Nykredit to advance its target to cut emissions from operations by 85% by 2030, the partners said. As part of the deal, Klimate has facilitated an investment in CDR credits generated by Danish biogas company Bigadan, which captures and permanently stores biogenic CO2. The companies added that this collaboration will support the development and scaling of high-integrity CDR solutions in Denmark.

ESG support – Brazilian bank Banco do Brasil (BB) and climate consultancy WayCarbon are preparing to launch an ESG advisory service next month to help 100 small and medium-sized Brazilian municipalities develop climate mitigation and adaptation projects. The Municipal Climate Management service, announced on May 20, developed with support from Brazil’s National Treasury Secretariat, is currently in testing and expected to become available in June. It will use artificial intelligence, monitoring technology, territorial diagnostics, and financial management tools to help local governments identify climate vulnerabilities, design adaptation measures, and structure projects suitable for fundraising. The service will be offered free of charge to participating municipalities, using resources provided under National Treasury Normative Ordinance STN/MF No. 808, BB said in a press release.

An Australian biochar developer has begun harvesting and pyrolysis trials at a project in North Queensland that aims to convert invasive woody biomass into biochar-based carbon removals (CDR).

The developer of the world’s largest direct air capture (DAC) facility has received backing to develop a new plant in North America alongside a mix of other carbon removal (CDR) projects.

Carbon credit registry and certification body Isometric has certified Version 2.1 of its standard, introducing a more streamlined validation process designed to accelerate the issuance of carbon removal credits.

A US-based land management company has secured just over $4 million from the sale of carbon credits generated from an improved forest management (IFM) project in Tennessee, it announced last week.

A French carbon standard last week opened a public consultation on a new module that would allow carbon credits to be issued from the use of bio-oil as a lower-carbon substitute for fossil-based asphalt binder.

Blue shift – A mangrove conservation project in Mexico developed by MarVivo has been archived on the US carbon offset platform Wren’s registry after its proponents shifted priorities away from carbon and towards community-driven educational efforts. The project description said the initiative aimed to protect nearly 15,000 hectares of mangrove forest in Baja California Sur, Mexico, through a proposed conservation arrangement intended to prevent activities such as aquaculture and mining in the area. Under a REDD+ framework, the project aimed to mobilise carbon finance to strengthen forest governance, support conservation activities, and fund community initiatives, following the guidelines set out by VM0007 - REDD+ Methodology Framework (REDD+ MF), v1.6.

Biomass-based carbon removal could help build the feedstock supply chains needed to scale sustainable aviation fuel (SAF) production, rather than competing with biofuels for limited resources, according to a paper released last week.

A Thailand-based digital services firm last week announced plans to issue a digital token in the third quarter of 2026, raising up to THB 480 million ($14.7 mln) for a mangrove reforestation project tied to 400,000 carbon credits.

A nature intelligence startup is working with Angolan land stewards to develop large-scale agroforestry initiatives in the country, using its technology to screen potential projects and reduce the risk of early-stage investment, just as the government begins building its carbon market framework.

Nearly three-quarters of low- and middle-income countries include clean cooking or wider household energy measures in their national climate plans, according to a new public tracker launched last week by a US-based non-profit.

A UAE law on corporate GHG reporting, planning, and management entered its compliance phase on May 30, but businesses are still largely unprepared, according to the chief executive of a Dubai-based sustainability consultancy speaking with Carbon Pulse.

For now, technology-driven activities dominate Latin America’s Article 6.2 Letters of Authorisation (LoAs), in a departure from the REDD-heavy profile of the local voluntary market (VCM) – but jurisdictional REDD+ (J-REDD+) is poised to flood both systems, Carbon Pulse has reported.
