Standards without standards - WTO members agreed at a meeting this week to begin voluntarily sharing information on their trade and climate measures, including data on embedded carbon emissions, on a pilot basis from the next Committee on Trade and Environment meeting in June. Members also raised concerns about the proliferation of carbon standards and the risks of fragmentation and higher compliance costs. China proposed a mapping exercise of carbon standards and a dedicated session at the WTO's Trade and Environment Week in June, while Japan circulated a template for cross-border emissions measurement information sharing. Least-developed members called for stronger technology transfer and technical assistance alongside any new transparency measures.

Ammonia ahoy – A cargo of green ammonia has been shipped from northern China to South Korea in what the producer described as the world’s first commercial end-to-end delivery spanning renewable hydrogen production and maritime export, it was announced this week. Chinese energy technology company Envision said the shipment departed from its Chifeng, Inner Mongolia facility, which it described as the world’s largest green hydrogen-ammonia base, and was delivered to LOTTE Fine Chemical. Envision claims a current output of 320,000 tonnes per year set to rise to 1.5 mln tonnes annually by 2028, while the green ammonia has secured ISCC EU, ISCC PLUS, and EU Renewable Fuels of Non-Biological Origin (RFNBO) certifications.

Marine carbon removal (mCDR) faces significant legal uncertainty under international treaties, which could constrain large-scale deployment, a new report said.

Global GHG emissions for 2025 increased 0.5% despite a small decline in the power sector, the largest source of emissions, according to a new report.

Article 6 engagement is building in the Caribbean, but to leverage opportunities in key sectors, an aggregative approach will be essential, according to a report published by a UN centre.

Norway will exempt most industrial installations covered by the EU Emissions Trading System from its domestic CO2 tax starting Mar. 1, marking a major shift in the country’s carbon pricing framework and delivering substantial cost relief to energy-intensive sectors including aluminium, cement, and chemicals.

European policymakers should maintain an open and competitive sustainable aviation fuel (SAF) market to avoid supply constraints and rising costs, a renewable fuels producer said Friday in a position paper.

Hydrogen imports into the EU will face carbon costs based on how they are produced under the bloc’s Carbon Border Adjustment Mechanism (CBAM), linking trade competitiveness to embedded emissions rather than how fuels are labelled, according to analysis published this week.

The rate of new clean cooking projects starting registration has fallen by a third after the introduction of tighter rules on calculating carbon credit volumes, but there has also been a jump in new entrants to the market, according to data from analysts.

Singapore will operationalise its bilateral carbon credit agreement with Thailand next month, the deputy prime minister said this week, as the city-state steps up efforts to secure offsets to meet its climate targets.
