BITE-SIZED UPDATES FROM AROUND THE WORLD

INTERNATIONAL

Conference crew – Brazil has appointed over two dozen prominent climate figures as envoys for COP30. The upcoming presidency name 10 envoys for strategic regions, as well as 20 for key sectors. The group includes former US climate diplomat Jonathan Pershing and China’s longtime climate envoy Xie Zhenhua, both instrumental in past US-China climate cooperation, as well as Laurence Tubiana, president of European Climate Foundation and a key Paris Agreement architect. The envoys will serve as liaisons to Brazilian leadership during the summit.

EMEA

CCS funding – The Danish Energy Agency has chosen 10 companies from a pool of 16 applicants to compete for 28.7 bln Danish krone (€3.8 bln) in funding for carbon capture and storage (CCS) projects. Funding will be paid out per tonne of CO2 captured and stored, with the CO2 required to be captured in country whilst it can be geologically stored either in Denmark or abroad. Pre-qualified companies can now submit detailed project descriptions and bids, with the deadline for submission of initial offers Aug. 26, 2025. A negotiation phase will then take place between the Danish Energy Agency and the bidders, with final and binding offers expected by Dec. 17, 2025. Contract awards are planned for Apr. 2026. The funding, which is subject to state aid approval from the European Commission, is expected to help reduce Denmark’s annual CO₂ emissions by 2.3 mln tonnes from 2030. Further details here on the selected 10 companies.

Nuclear is back – The Belgian Parliament has voted to scrap a 2003 nuclear phase-out law in a milestone for the country’s return to nuclear power. Thursday’s vote opens the door to nuclear new-build and lifetime extensions for existing plants. The law originally foresaw the phase-out of Belgium’s seven nuclear plants by 2025 and banned nuclear new-build. It has been regularly adapted over the years, however. The last government decided to give 10-year lifetime extensions to two plants over energy security worries on the back of Russia’s invasion of Ukraine. The new government, which took office earlier this year, aims for a nuclear revival in Belgium, including through the build-out of new plants. (HLN)

Partners – The Carbon Removers has selected Isometric as the registry for its flagship Danish project to permanently remove and store 50,000 tonnes of CO2 beneath the North Sea every year. The Biogenic Carbon Capture and Storage (Bio-CCS) project will remove and store CO2 as part of Project Greensand Future, which will be the first operational CO2 storage facility in the EU, the companies announced this week. This marks a significant milestone for The Carbon Removers as it expands from a pioneering pilot in Scotland to one of Europe’s first large-scale, registry-backed CDR deployments. Under the agreement, Isometric will oversee MRV and issue carbon removal credits, ensuring every unit meets the highest standards for scientific rigor and transparency. The partnership was announced on Wednesday by Isometric’s Founder and CEO Eamon Jubbawy and The Carbon Removers’ Co-Founder and Chief Carbon Officer Ed Nimmons at a panel hosted by BeZero Carbon and Lloyds Corporate & Institutional.

Risk behind closure – Taiwan is set to deactivate its last nuclear reactor this weekend, as part of a phaseout strategy that poses risks to the island’s energy-intensive semiconductor industry and its security, according to Bloomberg. Power demand is anticipated to rise 13% by 2030, largely driven by growing demand from data centres and chipmakers. Meanwhile, increasing fuel costs and renewable energy investments have weighed on the finances of state utility Taipower, which reported over NTD 420 bln ($14 bln) in accumulated losses at the end of last year. Given the situation, there have been signs that the government is softening its stance on nuclear phase-out, the report said, referring to a revised power bill.

Deadline extension – Taiwan has extended the deadline for companies regulated by the domestic carbon levy scheme to propose their voluntary carbon reduction plans by two months, in response to uncertainties regarding tariffs, the environment ministry said. Emitters are now required to submit their proposals by the end of August if they intend to apply the preferential rates. According to the ministry, nearly 90% of regulated companies are willing to apply for voluntary reduction plans. The carbon levy programme, which currently covers around 252 companies, is expected to help reduce emissions by up to 37 mln tonnes by 2030.

Pump it up – Australia heat pump company O’Brien based in Melbourne said Friday it had partnered with Finnish heat pump company Oilon to take delivery of what it calls “ the world’s most advanced high temperature heat pumps”. The pumps’ electric process can heat up to 120C. Heat pumps are increasingly being seen in Australia as an alternative to fossil fuels like gas but are usually residential options. O’Brien said the much higher heat, previously thought to be out of reach, was suitable for commercial and industrial purposes, making them a useful tool in wider decarbonisation.

Clean energy steps – Australia miner Fortescue has submitted environmental plans to the Western Australia environmental agency for a planned 2.1 GW wind farm in Marble Bar, in the state’s far north. The company has been planning to transition to renewable electricity over diesel for its mining operations for some time. The wind farm should be online by the end of the decade, with approvals expected some time next year.

CCU for cement – India’s Department of Science and Technology (DST) has unveiled five carbon capture and utilisation (CCU) testbeds in the cement sector, in a step to produce first-of-its-kind research and an innovation cluster to combat industrial carbon emissions. The testbeds will be set up in academia-industry collaboration under the public-private partnership (PPP) mode, and engage premier research laboratories as knowledge partners and top cement companies as the industry partners. Each testbed will address a different facet of CCU. The government expects to reduce the cost of green cement via the deployed CCU technology through continuous research and innovation in developing innovative catalysts, materials, electrolyser technology, reactors, and electronics, it said.

Green taxonomy – Kyrgyzstan’s cabinet has approved a green taxonomy for the nation with an aim to attract more green investments, support environmentally friendly projects, simplify state regulations, and strengthen the country’s position on the international sustainable finance market, Qazaq Green reported. The government has approved the first list of technologies, and goods and services in the country that can be considered environmentally friendly. The cabinet has also instructed different ministries to create an open database of “green” goods and services. As well, a simplified accounting of carbon emissions will be introduced, and a document will be developed confirming the compliance of the project with the taxonomy requirements. The green taxonomy will operate in pilot mode until the end of Jun. 2028.

Green reporting – United Overseas Bank (UOB) Malaysia has collaborated with the national bourse Bursa Malaysia to facilitate small and medium enterprises (SMEs) in adopting sustainability practices and advancing their decarbonisation journey, it said in a statement. The partners aim to equip SMEs to meet growing sustainability demands from stakeholders for their Scope 3 emissions reporting. The collaboration will help the bank expand its Sustainability Accelerator Programme 2.0 by providing its SME clients with access to Bursa Malaysia’s Centralised Sustainability Intelligence (CSI) solution, reducing complexities of emissions calculations, and facilitating uptake of decarbonisation solutions, it said. The platform already supports Scope 1 and Scope 2 disclosure requirements. With the Scope 3 emissions disclosure requirement commencing in phases, starting 2027, SMEs within the public-listed companies’ supply chains will need to be prepared to meet these reporting obligations, it added.

In the woods – Japanese oil company Eneos has teamed up with the government of Ichinoseki city in Iwate prefecture, for the implementation of a forest-based J-Credit project in the region, it announced Friday. The project is expected to generate around 27,000 credits over eight years. Eneos will use credits generated from city-owned forests to offset CO2 emissions from its business activities in the Tohoku region.

Little help please – The United Nations Development Programme (UNDP) in Vietnam has issued Request for Proposal UNDP-VNM-01474, seeking a qualified national consultancy firm to carry out a study on the country’s compliance with CORSIA. The study, scheduled to run from June to August 2025, aims to evaluate Vietnam’s readiness to meet CORSIA’s requirements, including assessing current emissions data, institutional arrangements, and MRV systems. The selected firm will be expected to identify policy and capacity gaps and provide recommendations to align Vietnam’s aviation sector with international standards. Proposals must be submitted by May 28 via the UNDP eTendering platform. Further details and submission guidelines are available on the UNDP procurement website.

High hopes for hydrogen – Newfoundland and Labrador’s provincial government announced a $50,000 contribution on Thursday to support a $400,000 project led by the Atlantic Hydrogen Alliance aimed at assessing and advancing Atlantic Canada’s hydrogen supply chain. Conducted in collaboration with Energy NL and Net-Zero Atlantic, the project seeks to define the regional hydrogen value chain, benchmark existing capabilities, and develop a plan to strengthen the region’s position in hydrogen development. Stakeholder engagement is expected to include Indigenous and rural communities. The grant is part of the province’s Innovation and Business Development Fund, which supports energy sector growth and diversification.

Big Beautiful No – The House Budget Committee voted down the federal budget bill Friday on a 16-21 vote. A number of Republicans joined all Democrats in voting against the bill, which outlines spending from 2026-34. GOP lawmakers are pushing for steeper spending cuts, several media outlets have reported, and negotiations are expected to continue through the weekend. Earlier proposals from the House Energy and Commerce Committee pushed for environmental cuts totalling just under $40.6 bln, while the House Ways and Means Committee moved to slash a number of tax credits for electric vehicles, CO2 storage, and hydrogen. President Donald Trump has called on elected officials to unite in passing the “big, beautiful bill” in line with his wish list of spending cuts.

Explain, please – A group of Democratic members of Congress sent a letter on Thursday to the CEOs of major US financial institutions, expressing concern over their recent withdrawal from global climate coalitions such as the Net Zero Banking Alliance and Climate Action 100+. The lawmakers criticised the banks’ reversal of climate commitments, citing increasing economic risks from climate-related disasters and the financial sector’s exposure to these risks through lending and investment portfolios. They requested written responses by May 29 on whether the firms remain committed to their net zero goals, plan to disclose emissions progress, and have communicated with the Trump administration regarding directives to halt ESG activities.

Red light for green buses – The US Department of Transportation (DOT) announced Friday $1.5 bln in funding for projects that expand bus manufacturing under the Federal Transit Administration, without requirements related to climate change, sustainability, environmental justice, and diversity, equity, and inclusion (DEI) — as established by the former Biden-administration. The removal meant manufacturers could get back to basics and focus on building ‘big, beautiful transit systems’ DOT said in the notice.

Crowd sourcing cuts – The US Department of the Interior issued a request for information (RFI) Friday asking the public to identify existing regulations that the department could modify or repeal. According to a notice published in the Federal Register, the request is part of the President Trump’s directive to deconstruct the regulatory burden “that has been self-imposed” on the nation and improve regulatory processes. The agency will field responses for 30 days beginning May 20.

Green groups, green money – Some of the largest US environmental non-profits paid their top executives more than $1 mln, according to recently released tax records, where disclosures lag by several years. The Internal Revenue Service released publicly available tax records of tax-exempt entities for years 2022 and 2023, revealing that organisations such as the Environmental Defense Fund (EDF) and the World Wildlife Fund (WWF) paid their executives handsomely. EDF President Fred Krupp for 2022 and WFF CEO Carter Roberts for 2023 both earned more than $1 mln, as first reported by E&E News.

Onwards and onwards – Two North Dakota judges have separately permitted lawsuits filed by landowners against project developer Summit Carbon Solutions (SCS) to proceed, the North Dakota Monitor reported this week. The company filed motions to dismiss the lawsuit in March, but South Central Judicial District Court Judge Pam Nesvig and South Central Judicial District Court Judge Jackson Lofgren each rejected SCS’ arguments. SCS’ effort to develop a CO2 pipeline through the state has been fraught with pushback from landowners, who have taken other legal means to dispute the grounds for development, such as a case filed in the state’s highest court against a 2009 law that authorises pore space consolidation from multiple landowners.

Court reverses course – A federal appellate court ordered the US EPA to revisit a decision it made nearly 10 years ago relating to a Texas power plant’s compliance with air quality standards. On Friday, the 5th US Circuit Court of Appeals said that the agency “seems to have forced a result on sparse and suspect evidence” when it decided that the area surrounding the coal-fired Martin Lake Power Plant in northeast Texas did not meet its 2010 ambient air quality standard for sulphur dioxide, E&E News reported. The ruling comes more than a year after the same court previously upheld the EPA’s decision to declare the area in non-compliance. This time, the court’s reversal cited the Supreme Court case that overturned the Chevron doctrine, which curbed federal agencies’ regulatory latitude.

Safeguard standards – Brazil’s Technical Working Group (TWG) on Safeguards has concluded discussion of the draft guidelines for the implementation of J-REDD+ programmes and public and private forest carbon credits on public lands occupied by Indigenous peoples, quilombola communities, traditional peoples and communities, and family farmers settled by agrarian reform. The proposal will be forwarded for deliberation by the National Commission for REDD+ (CONAREDD+) at a meeting scheduled for May 28 at the environmental ministry. The proposal establishes socio-environmental safeguards and guidelines aimed at ensuring respect for territorial rights, traditional ways of life, and autonomy for these groups. Agreed-upon points include: the obligation of free, informed, and prior consent (FPIC); the need for independent technical and legal advice for communities, funded by resources provided for in the project; a lack of restrictions on access to and use of territories for traditional and sustainable activities; accessible language in the disclosure of results and contracts; and inclusion of women, young people, and the elderly in project decision-making, management, and implementation.  

SCIENCE & TECH

Hard to find – Deposits of white hydrogen, or natural hydrogen trapped in the earth’s Precambrian crust, could be the equivalent to approximately 170,000 years of present-day oil use, but it is likely that finding very high concentrations of hydrogen will be exceptional, a study by scientists has claimed. Gas accumulations of high-purity (above 90%) hydrogen are known to occur, but hydrogen mixed with helium, nitrogen, and other gases are predicted in most rock formations, the paper in Nature Reviews, Earth & Environment said. Several companies are seeking to find large deposits of white hydrogen that will be as cheap to extract as oil, with production costs as low as €0.50/kg compared to €3-7 for green hydrogen from electrolysis. France may have discovered large white hydrogen reserves in Lorraine’s Moselle region, after an initial discovery in May 2023 was then followed by more announced findings last month. The white hydrogen reserves found in the region alone are estimated to account for some 42 mln tonnes and valued at $92 bln, although it could be as much as 250 mln tonnes, and potentially revolutionise clean energy, researchers have said.

AND FINALLY…

Urine luck – Researchers from the University of Adelaide and the Australian Research Council Centre of Excellence for Carbon Science and Innovation have developed two energy-efficient electrolysis systems that generate hydrogen from urea in urine and wastewater, potentially offering a low-cost alternative to traditional water-splitting methods. According to the researchers, the systems reduce electricity use by 20-27% compared to conventional electrolysis and address limitations of existing urea-based systems by avoiding the production of toxic by-products such as nitrates and nitrites. One system uses pure urea in a membrane-free design, while the other overcomes chloride-related corrosion in urine using a novel platinum-based catalyst. The research, published in Nature Communications, aims to support the development of green hydrogen production methods and nitrogen waste remediation.
