PPM panic - Scientists from the US National Oceanic and Atmospheric Administration (NOAA) and Scripps Institution of Oceanography at the University of California San Diego reported that atmospheric CO2 concentrations at NOAA’s Mauna Loa Observatory surpassed 430 parts per million (ppm) for the first time during this month. Scripps measured an average of 430.2 ppm, while NOAA recorded 430.5 ppm, both reflecting an increase of over 3.5 ppm from May 2024. The Mauna Loa Observatory, situated on Hawaii’s Mauna Loa volcano, is considered as a benchmark for global CO2 monitoring.
- Thu 23:19Rage against the disinformation machine - French President Emmanuel Macron and Brazilian President Luiz Inacio Lula da Silva on Thursday jointly reaffirmed their commitment to global climate action and combating climate disinformation. In a joint France-Brazil press release, the two leaders urged other nations to join the Global Initiative for Information Integrity on Climate Change, a Brazil-led multilateral effort supported by the UN, UNESCO, France, and others. The initiative seeks to counter false or misleading narratives about climate change through measures such as supporting independent journalism, protecting environmental defenders, and advocating for democratic regulation of digital platforms. It recognises that safeguarding information integrity is essential for effective climate policy, particularly in the face of targeted disinformation campaigns driven by fossil fuel interests and tech platforms. Proposals are being invited to strengthen this effort.

SAF study - During the 2025 International Civil Aviation Organization (ICAO) Aviation Climate Week, held from Jun. 2-4, Airbus and Mexican airline Volaris announced a Letter of Intent to contribute to ICAO's Voluntary Environment Fund through a study on Sustainable Aviation Fuel (SAF) production in Mexico. Conducted through ICAO’s Assistance, Capacity Building and Training for SAF (ACT-SAF) Programme, the study is expected to assess policy frameworks, feedstocks, and production pathways. The partnership aims to advance SAF deployment to help achieve ICAO’s net zero emissions goal for aviation by 2050.
- Thu 17:00Global sustainable aviation fuel (SAF) demand is set to reach around 2 million tonnes in 2025, but reliance on limited feedstocks could constrain growth beyond 2030 unless alternative production pathways are rapidly scaled, according to a market outlook released Thursday.
- Thu 16:45Microsoft continued to support the engineered carbon removal (CDR) market in May, accounting for lion’s share of the 3.48 million tonnes of forward purchase agreements, according to data platform CDR.fyi.
- Thu 16:06The carbon removal sector is in the midst of a crisis despite record offtake volumes this year, driven in part by the scramble to secure venture capital to scale nascent technologies — but there is now clear movement towards sovereign backing of the industry, experts told an event on Thursday.
- Thu 15:55Project developers are stepping up their campaign to tone down cookstove methodology requirements by calling on the UNFCCC Clean Development Mechanism’s (CDM) Board to review outdated science that could lead to under-crediting.
- Thu 15:22A large voluntary carbon project developer has called for greater alignment among the buyers of credits for new schemes to help unlock high-quality supply.
- Thu 14:56Art 6 tracker - Climate Action Center of Excellence (CACE) together with Emsurge has launched an Article 6 tracker to help public and private sector stakeholders assess the national readiness for more than 140 countries to participate in high-integrity carbon markets under Article 6 of the Paris Agreement. The tracker covers all 141 countries eligible for Official Development Assistance (ODA), as listed by OECD/DAC. It covers sectoral analysis of NDC targets, readiness status of Letters of Authorisation, tracking systems, bilateral agreements, and transparency reports. Plus other insights to inform investment and policy. Designated National Authorities (DNAs) can access the pilot version for free by registering here.
- Thu 14:11Stakes are high for efforts to tackle the marine biodiversity crisis when France next week hosts the UN Ocean Conference (UNOC).
- Thu 13:38Tech companies around the world saw their operational emissions rise by 1.4% between 2023 and 2024 as data centres continued to eat up electricity — despite more companies setting reduction targets, according to a report published on Thursday.
- Thu 13:35A Singaporean exchange has stolen a march on its rivals in the fiercely competitive market for benchmarking carbon prices, after reporting an offer for CO2 tonnes on a floating price basis versus its Phase 1 CORSIA index.
- Thu 13:11The European Commission will put forward its 2040 climate target proposal on July 2, a crucial step that officials said will "inform" the EU’s updated Nationally Determined Contribution (NDC) to the Paris Agreement.
- Thu 12:58The Article 6.4 Methodological Expert Panel (MEP) has launched a call for public consultation of the first proposed methodology under the Paris Agreement Crediting Mechanism (PACM), it announced Thursday.
- Thu 09:53Global economies and societies are linked to forests in a deeper way than previously thought, meaning governments need to have a long-term approach to ensuring their survival, according to a global report by scientists.
- Thu 08:14Singapore and the Philippines are working to finalise a legally binding deal to operationalise a carbon credits partnership under Article 6 of the Paris Agreement, Singapore Prime Minister Lawrence Wong said this week.
- Thu 07:22Show me the money - The government of Zambia is set to receive $30 mln from the World Bank in results-based payments to reduce 3 MtCO2e over 2024-29 under the Eastern Province Jurisdictional Sustainable Landscape Programme, it announced this week. The nation formally signed a Nested Emission Reduction Performance Agreement (NERPA) with the World Bank last year to undertake activities such as forest conservation, climate-smart agriculture, use of fuel-efficient cookstoves, and sustainable charcoal production. Earlier this week, it also signed an MoU with the Community Markets for Conservation (COMACO), it said.
- Thu 07:20COP commitment - The South Australian government has committed A$8.4 mln ($5.1 mln) over two years to support the state's preparation for Adelaide to host COP31 in Nov. 2026, should the federal government be successful in its bid, according to its state budget. The budget papers note the annual meeting will bring together world leaders to assess progress on climate change. The state government spending comes on top of the A$75 mln that was committed by the federal government in March. Australia is looking to host UN talks in partnership with the Pacific, however, Turkiye is still competing to secure the bid.
