The government of Argentina's Misiones has signed a memorandum of understanding (MoU) with Verra to strengthen the province's technical capacity to participate in international carbon markets, following the standard's recent approval of its landmark jurisdictional forest carbon programme.

EMH-SAF partnership - Low-carbon hydrogen producer Vema Hydrogen has partnered with international developer SAF+ International Group, announcing on Tuesday the signing of a MoU to pair engineered mineral hydrogen (EMH) with sustainable aviation fuel (SAF), aiming to increase SAF supply and reduce barriers that limit adoption. The agreement establishes a framework under which Vema will supply more than 4,000 tonnes per year of hydrogen beginning in approximately 2028 from its Quebec EMH project. This will be the province's first integrated EMH-to-SAF ecosystem amid a growth a global aviation decarbonisation mandates, the pair said.

Fusion race - Proxima Fusion, which is looking to build Europe’s first commercial fusion power plant, has raised €411 mln ($468 mln) in a financing round, with RWE and Google as strategic investors, it announced Tuesday. The financing provides the backing needed to build Alpha, Proxima’s net-energy stellarator demonstrator near Munich, Germany. In less than three years, Proxima has secured more than €650 mln ($740 mln), including €95 mln in public grants.

Koko Networks, the Kenyan-based bioethanol and clean cooking developer that folded in February after failing to secure an agreement to sell credits internationally under the Paris Agreement, is selling its technology platform and factory.

Underfunding of the Loss and Damage fund risks bleeding into broader UN climate negotiations, hardening developing countries' reluctance to raise mitigation ambition without matching finance, experts warned ahead of a critical meeting this week.

The EU should use its quota for international carbon credits to help build domestic carbon pricing systems in partner countries, rather than treating them as a cheaper route to fulfilling its 2040 emission targets, according to a recent policy brief.

Producing sustainable aviation fuel (SAF) from waste plastics could act as a “bridging fuel” in decarbonising aviation before the scale-up of other fuels with a stronger emissions saving profile, say experts.

Sinking conviction - The shipping industry's support for green fuels is on the decline as most vessel owners stick to conventional fuels or alternatives like nuclear, the FT reported. Conviction that ammonia will become commercially viable in the next decade fell from 31% of shipping executives last year to 12% this year, while belief in hydrogen fell from 18% to 10%, according to data from the International Chamber of Shipping's latest annual survey. In contrast, backing for traditional fuels as the most viable option rose from 41% last year to 50%, despite the disruption of the Iran war. The challenge of accessing greener fuels has led many shipowners to order an increasing number of dual-fuel vessels, while some have reverted to new builds powered by fossil fuels. A few shipowners are considering carbon capture technologies, including the container line Hapag-Lloyd, and there's also been a clear increase in enthusiasm for nuclear propulsion, including from Core Power, which is developing a nuclear-propelled fleet.

Verra has high hopes for growth via regulated carbon markets after issuances under its flagship carbon standard fell by around 30% year-on-year in 2025, according to its annual report.

An Asian airline has retired another 100,000 carbon credits to meet its obligations under the aviation sector’s international offsetting programme, taking its recent total to 250,000 tonnes after the second tranche.

Gold Standard (GS) has added another insurance policy to the list of approved covers for CORSIA, the international aviation offsetting scheme, the registry announced Tuesday.
