The seasonal migration of zooplankton such as krill plays a key role in storing CO2 in the Southern Ocean, though these dynamics are at risk of being disturbed by climate change, a new study has found.

Australia on Friday began a public consultation process for sea dumping carbon capture and sequestration (CCS), releasing draft guidance documents for domestic projects.

A Dutch project developer has sold voluntary credits at an average of €22.28 ($26), higher than originally estimated, it revealed Friday.

Prices in China's national carbon market continued their recovery for the third consecutive week, with trading volumes almost doubling from the previous week. 

The EU needs time for a genuine democratic debate on the bloc’s next climate target for 2040, according to French President Emmanuel Macron, who has pleaded for decoupling the negotiations from the EU’s 2035 contribution to the UN due in September.

Getting to grips with Article 6 - The Climate Action Center of Excellence (CACE) and Emsurge are making the A6 Country Readiness Tracker free to access for carbon buyers, airlines, developers, Emstream clients, banks, government stakeholders, and climate investors. The decision, announced during London Climate Action Week, is intended to provide governments and investors with the information needed to make responsible decisions about the Article 6 market for international carbon trading. It will be free for eligible participants, but will carry a $5,000/year per location license for OECD-based firms not actively engaged in trading or implementation, said the press release.

Australia’s next Nationally Determined Contribution (NDC) will likely create the need for faster Safeguard Mechanism baseline decline rates, potentially leading to vastly higher Australian Carbon Credit Unit (ACCU) prices, according to analysis shared exclusively with Carbon Pulse.

Reducing data centre emissions - Singapore-based AI and IoT tech company Univers has partnered with Microsoft to accelerate energy transition using advanced AI and cloud technologies, the company said in statement. Announced at the London Climate Action Week, the partnership will integrate Univers’ EnOS Ark platform with Microsoft’s AI and data capabilities to help organisations track, manage, and reduce their energy consumption and carbon emissions - starting with energy-efficient data centres. As well, the initiative will aim to improve cooling efficiency, renewable energy integration, and intelligent operations within data centres worldwide.

Betting on batteries - Australia passed law Friday to ensure lower prices for home batteries, the Clean Energy Regulator announced. The Renewable Energy (Electricity) Amendment (Cheaper Home Batteries Program) Regulations 2025 expands existing regulations from 2001 and confirms solar batteries are eligible under the Small-scale Renewable Energy Scheme from Jul.1. Canberra’s A$2.3 bln ($1.5 bln) Cheaper Home Batteries Program aims to reduce the upfront costs by around 30%.

Net zero by 2060, first! - Indonesian President Prabowo Subianto claimed this week his nation will be one of the first to hit net zero, despite an official target of 2060 or 10 years after most nations. According to the President’s website, he made the promise via a videolink message to the inauguration of a renewable energy development as well as an oil block expansion boosting production by 30,000 barrels per day. He said the country was in a strong position to become "one of the first countries to achieve net zero emissions on time". Separately, an Indonesian energy think tank on Friday proposed five measures the government could take if it is serious about using the renewable energy potential of Central Java to generate hundreds of gigawatts of power. The Institute for Essential Services Reform (IESR) suggested Jakarta develop a green investment roadmap from now to 2035, establish a green investment unit as a ‘one-stop’ for investors, launch a Green Industrial Parks initiative in strategic areas, partner with financial institutions to explore green financing, and invest in green skills training. A separate report of this week found that Indonesia’s vast upstream coal sector is so profitable miners have little incentive to change or meet the eventual energy transition.

Renewable recharge - One of Australia’s large conglomerates that owns hardware and office supply stores and a large chemical arm will fast track decarbonisation via a A$100 mln ($66 mln) funding commitment from the Clean Energy Finance Corporation (CEFC), it announced. The funding will be used to install distributed energy resources (DER) across operations including rooftop solar, battery storage, energy efficiency initiatives, and an electric vehicle smart charging infrastructure pilot. Wesfarmers will also conduct a study to decarbonise its chemical arm. Wesfarmers said it expects to have installed or upgraded onsite renewables at its retail outlets by the end of the year. Visitors to hardware outlet Bunnings will also be able to use onsite EV chargers.

Disappointing - Australia’s Clean Energy Council (CEC) has expressed dismay at Queensland’s parliament passing renewable energy planning reforms without amendment, it said this week. The Social Impact and Community Benefit bill will add complexity and delay approvals for new grid-scale projects, according to the NGO. It will also put investment in the Sunshine State at risk, it said, even as it welcomed the plan to better consult with communities. The CEC said renewable investors are already hesitant to continue projects, which may ultimately delay the exit of coal. Earlier this year the state paused the approvals process for several large gigawatt-scale windfarms for several months over claims they failed to properly consult with local communities.

Getting recognised - Australian analysis firm RepuTex has had its Australian Carbon Credit Unit (ACCU) price benchmark recognised as the "Default Prescribed Unit Price" (DPUP) by the Australian government, it announced Friday. The recognition sets the standard price for prescribed carbon units under the Safeguard Mechanism. The DPUP is an average of prescribed carbon unit trades for a financial year, including ACCUs and Safeguard Mechanism Credits, and provides the market with a standard benchmark for calculating the cost of managing excess emissions - linked to an audited reference price, the firm said. RepuTex said interim estimates of the DPUP will be published by the government on a quarterly basis.

Benchmark California Carbon Allowance (CCA) prices rose above $28 amid fading fears of federal risks and bullish signals, while Washington Carbon Allowance (WCA) values recorded multi-year highs on constrained permit supply.

A majority in the Dutch Parliament has voted in favour of scrapping a national CO2 levy on industry that sits on top of the EU ETS – after the government only recently proposed to maintain it.

The Q1 2025 results for carbon offsetting under Colombia’s national CO2 tax have this week been published, showing higher retirements that build upon recent rebounds in local demand after post-2022 lows.
