New research shows that the shipping industry could reduce a sizeable chunk of its CO2 emissions by ditching “first-come, first-served” port arrival systems and implementing queueing systems that don’t incentivise ships to rush to their destination.

A representative of the Brazilian COP30 presidency said during a webinar Wednesday that the nation is keen to draw focus to carbon markets at the upcoming climate talks.

Wet data - On Wednesday, CarbonPlan released a new, model-based dataset and tool to help characterise how well direct ocean removal (DOR), a marine CDR approach, works depending on where and when it is performed.

The lower house of the Moroccan legislature on Monday passed a bill empowering a domestic body to issue certificates validating companies’ reporting about embedded carbon, as the North African government prepares for EU CBAM compliance from 2026.

A quiet place - Net zero is entering an era of quiet progress, according to Michelle You, CEO of Supercritical, in an op-ed published Wednesday on the WEF website. She highlighted a significant shift in corporate climate strategies. While public climate commitments and high-profile pledges have diminished, companies are intensifying their efforts to achieve net zero emissions through substantive actions, particularly focusing on durable carbon removal, she added.

Clear as mud - The latest draft version of the CLEAR cookstoves methodology, along with an updated explanation of decisions document, will be posted on the 4C website in June, the organisation said. This compared to a previous end-of-May expectation. UN officials tasked with helping to shape the PACM are also due to review and discuss a new clean cooking crediting programme at the next methodological expert meeting in the summer.

A technology company that uses artificial intelligence to uncover root scope 3 emissions has raised $30 million in Series B funding.

The EU ETS and UN CORSIA international aviation offsetting scheme have a "collaboration issue" which will come to a head in 2027, according to a new report from an international consultancy.

2 become 1 - Another milestone has been reached in the race to make nuclear fusion a commercial reality after the Wendelstein 7-X team achieved a new world record for the 'triple product' in long plasma discharges. The US and European collaboration raised the plasma temperature to more than 20 mln C, hitting a peak 30 mln C for 43 seconds, surpassing the best performances of fusion devices of the tokamak type for longer plasma durations. The triple product — also known as the Lawson criterion — is the key metric for success on the path to a fusion power plant. Only when a certain threshold is exceeded can a plasma produce more fusion power than the heating power invested. This marks the point where the energy balance becomes positive, and the fusion reaction can sustain itself without continued external heating. During the experiment, another two milestones were achieved. Energy turnover was increased to 1.8 gigajoules, with a plasma duration of 360 seconds. The previous record from Feb. 2023 was 1.3 gigajoules. Plasma pressure relative to magnetic pressure reached 3% for the first time across the full plasma volume. This ratio is a key parameter for extrapolating to a fusion power plant, where 4–5% across the volume will be needed.

May saw a major jump in issuances in the voluntary carbon market (VCM), while monthly retirements also soared 75% year-on-year, putting the market back on track for a record year, new Carbon Pulse analysis of registry data shows.

Brazil's Federal Public Ministry (MPF) filed a lawsuit Tuesday requesting the immediate suspension of an international contract for the purchase and sale of carbon credits signed between the state of Para and a coalition of international governments and multinational corporations.
