India and South Korea have signed a cooperation agreement under Article 6.2 of the Paris Agreement. This is a key step for creating cross-border carbon markets between these two major Asian economies.

The deal was signed when the South Korean president visited India. More than a dozen agreements were made about clean energy, trade, and industrial cooperation. It reflects growing global interest in carbon trading as countries seek cost-effective ways to meet climate targets.

The agreement allows both countries to cooperate on emissions reduction projects and exchange carbon credits. This could open up new sources of climate finance and help decarbonize sectors like energy, industry, and transport.

How Article 6.2 Unlocks Cross-Border Carbon Trading

Article 6.2 of the Paris Agreement allows countries to trade emission reductions through bilateral or multilateral deals. These are known as “internationally transferred mitigation outcomes” (ITMOs).

Each ITMO represents one tonne of carbon dioxide equivalent (tCO₂e) reduced or removed. Countries can invest in emissions-cutting projects abroad and count those reductions toward their own climate targets.

A key rule is the “corresponding adjustment.” The host country must add the sold emissions back to its carbon balance. This prevents double-counting and ensures transparency.

This system improves on older carbon markets under the Kyoto Protocol. It links carbon trading directly to national climate targets and strengthens accountability.

Although Article 6.2 is still new, activity is growing quickly.

• Around 58 bilateral Article 6.2 agreements have already been signed globally.
• At least 68 pilot ITMO projects are under development worldwide.
• More than 100 countries have signaled interest in using Article 6 mechanisms.

Here are key examples of these agreements, as shown in the World Bank carbon pricing dashboard:

Most early projects are in developing countries. These nations can supply carbon credits while receiving investment and technology. Buyers are often developed countries with stricter climate targets and higher costs of domestic emissions reduction.

India and South Korea confirmed that their agreement will support:

• Investment-driven mitigation projects, 
• Development of carbon markets, and
• Cooperation in renewable energy and low-carbon technologies. 

This is a major step because global carbon markets are still in early stages. Many countries are now building bilateral agreements to operationalize Article 6 mechanisms.

The deal also aligns with a broader shift toward market-based climate solutions. These mechanisms are seen as a way to lower the cost of achieving national climate targets.

Net Zero Targets Drive Bilateral Climate Cooperation

The agreement is closely tied to both countries’ long-term climate goals. India has committed to reaching net-zero emissions by 2070. South Korea has set an earlier target of 2050.

These timelines create both challenges and opportunities. South Korea is a developed economy with limited land and resources. So, it may look for cost-effective ways to cut emissions abroad.

India, as a fast-growing economy, offers large-scale opportunities for clean energy and carbon reduction projects. This creates a natural partnership. The two countries also agreed to expand cooperation in:

• Renewable energy, 
• Green hydrogen, and 
• Low-carbon industrial technologies.

These sectors are critical for reducing emissions in hard-to-abate industries such as steel, cement, and heavy transport. Both countries also reaffirmed their commitment to the Paris Agreement and global climate action.

Carbon Markets Poised for Rapid Global Growth

The India–South Korea deal comes as global carbon markets are expected to expand significantly over the next decade.

Carbon pricing systems already cover about 28% of global emissions, according to the World Bank’s 2025 State and Trends of Carbon Pricing report. At the same time, voluntary carbon markets and compliance markets are evolving rapidly.

Analysts expect carbon markets to grow into a multi-billion-dollar sector by 2030, until 2050, driven by:

• Net-zero commitments from over 140 countries,
• Increasing corporate climate targets, and
• Rising demand for carbon offsets.

Article 6 agreements are expected to play a key role in this growth. They provide a formal framework for cross-border carbon trading, which has been limited in the past.

For emerging economies like India, this could unlock new sources of climate finance. For developed economies like South Korea, it offers flexibility in meeting emissions targets.

Economic Ties Expand Alongside Climate Cooperation

The carbon agreement is part of a broader expansion in India–South Korea relations. The two countries aim to double bilateral trade from about $27 billion today to $50 billion by 2030.

They also signed multiple agreements covering clean energy and critical minerals,  shipbuilding and manufacturing, and semiconductors and digital trade. This reflects a wider strategy to align economic growth with sustainability goals.

Both countries are working to build resilient supply chains in key sectors such as batteries, energy, and advanced manufacturing. These industries are essential for the global energy transition.

The partnership also includes efforts to improve energy security. This is especially important as global energy markets face volatility due to geopolitical tensions.

A Strategic Shift in Global Climate Cooperation

The signing of the Article 6.2 agreement marks a broader shift in how countries approach climate action. Instead of relying only on domestic measures, governments are increasingly turning to international cooperation. This allows them to share technology, reduce costs, and accelerate emissions reductions.

For India, the agreement opens new opportunities to attract climate finance and scale up clean energy projects.

For South Korea, it provides access to cost-effective mitigation options and supports its net-zero strategy.

The deal also strengthens the strategic partnership between the two countries. It links climate action with trade, technology, and industrial policy.

As more countries adopt similar agreements, Article 6.2 could become a central pillar of global carbon markets. This would reshape how emissions reductions are financed and delivered worldwide.

The Big Picture: Carbon Markets Move From Concept to Reality

The India–South Korea Article 6.2 agreement is more than a climate deal. It is part of a larger shift toward market-based decarbonization and international cooperation.

With global carbon markets set to expand and net-zero targets tightening, such partnerships are likely to increase.

For both countries, the agreement offers a pathway to balance economic growth with climate goals. It also signals growing momentum behind carbon trading as a key tool in the global energy transition.

As implementation begins, the real impact will depend on how quickly projects are developed and how well carbon markets scale. But the signal is clear: cross-border climate cooperation is moving from theory to practice.

The post Samsung SDI Signs $6.8 Billion Multi-Year EV Battery Supply Deal with Mercedes-Benz appeared first on Carbon Credits.

USA Rare Earth is making a big move in the critical minerals space. The company plans to acquire Brazil’s Serra Verde for $2.8 billion. This deal includes $300 million in cash and 126.9 million new shares. This values Serra Verde at about $2.8 billion based on USA Rare Earth’s share price from April 17. The acquisition is expected to close in the third quarter of 2026.

This purchase connects one of the few heavy rare earth producers outside China with USA Rare Earth’s growing mine-to-magnet platform. It aims to create an integrated supply chain for mining, processing, and magnet manufacturing. This is key as governments and industries want to reduce their reliance on Chinese supplies.

Barbara Humpton, Chief Executive Officer of USA Rare Earth, stated:

“The acquisition of Serra Verde represents a transformational step in delivering on our ambition to build a global champion and the partner of choice in rare earth elements, oxides, metals and magnets. Serra Verde’s Pela Ema mine is a one-of-a-kind asset and the only producer outside Asia capable of supplying all four magnetic rare earths at scale, together with other vital REEs, such as Yttrium. Serra Verde’s global importance is evidenced by its 15-year offtake agreement with a special purpose vehicle capitalized by various U.S. Government entities, as well as private capital sources, for 100% of its Phase 1 Nd, Pr, Dy and Tb production.

By combining Serra Verde’s world-class operations and team with our processing, separation, metallization and magnet-making capabilities, we are advancing our goal of creating a fully integrated platform that will serve as a cornerstone of global rare earth supply security for decades to come.”

Serra Verde Adds Heavy Rare Earth Supply the West Has Been Missing

Serra Verde provides access to heavy rare earths like dysprosium, terbium, and yttrium. These materials are essential for permanent magnets in electric vehicles, wind turbines, robotics, and defense tech. Sourcing them outside China is challenging. Supply concerns are rising as demand grows.

Many Western projects focus on light rare earths, but Serra Verde offers valuable heavy elements. Its Pela Ema mine in Goiás began production in 2024 after over $1.1 billion in investments. It became the first operational ionic clay deposit in the West.

REEs from clay deposits at Pela Ema

• By 2027, Phase 1 is projected to produce about 6,400 metric tons of total rare earth oxide annually. The mine aims to supply over 50% of non-China heavy rare earths by 2027. These figures boost the asset’s strategic value, with growth potential beyond current operations.
• A Phase 2 expansion could double production.

This growth aligns with USA Rare Earth’s goal of building a complete rare earth supply chain. Serra Verde adds feedstock production, while Round Top in Texas offers another source of heavy rare earths. Together, these assets strengthen the upstream supply base. But the story goes beyond mining.

Building a Vertically Integrated Rare Earth Platform

USA Rare Earth has spent years creating a vertically integrated platform. They acquired Less Common Metals in the UK, adding rare earth metal, alloy, and strip-casting capabilities. An Oklahoma magnet plant, launching later this year, will enhance downstream manufacturing.

With Serra Verde, these assets connect Brazilian feedstock, U.S. project development, European metallization, and U.S. magnet production.

Closing the Weak Links in the Supply Chain

According to the U.S. Geological Survey’s Mineral Commodity Summaries 2025, rare earth supply remains highly concentrated, with China continuing to dominate both mining and, more importantly, processing and magnet production.

Thus, this integration is crucial. Supply chain gaps have hindered Western rare earth ambitions. Mines without processing capacity face bottlenecks. Processing without secure feedstock risks supply. Magnet manufacturing without reliable materials can leave operations vulnerable.

This deal addresses these issues by combining multiple stages of the value chain. Strategic highlights from the acquisition show expansion opportunities across nearly every part of the platform.

• Upstream Supply Base: Upstream, Serra Verde’s Phase 2 growth paves the way for larger production volumes, while Round Top adds long-term potential. On the processing side, USA Rare Earth gains separation expertise through its partnership with Carester and plans to develop a rare earth carbonate separation line.
• Processing and Metallization Capacity: In metallization, the company aims to expand Less Common Metals’ reach in France, the U.S., and other markets to increase non-China metal, alloy, and strip-cast output.
• Downstream Magnet Manufacturing: Downstream, management sees potential to grow magnet manufacturing capacity for industrial customers focused on supply security. Together, these initiatives create a strategy that scales the entire supply chain rather than adding isolated assets.

Financial Structure Designed to Reduce Risk and Support Growth

The deal includes financial features aimed at reducing risk while supporting growth. Serra Verde secured a $565 million financing package from the U.S. International Development Finance Corporation to fund expansion through positive cash flow.

This eases financing pressure and supports scaling. It also has a 15-year, 100% offtake agreement for neodymium, praseodymium, dysprosium, and terbium, with minimum price floors, improving revenue stability and limiting commodity price risk.

Serra Verde expects $550–650 million in annualized EBITDA by 2027, with the combined company targeting about $1.8 billion by 2030 and roughly 80% cash flow conversion. The projections underline the deal’s transformational nature, focused on earnings growth and supply chain resilience.

 USA Rare Earth (USAR) Stock Jumps 15%

Meanwhile, USA Rare Earth secured a separate $1.6 billion funding package from the U.S. government earlier this year. The company expects more than $3.2 billion in pro forma liquidity, which includes around $1.2 billion in cash and $1.8 billion from milestone-based funding. This funding comes from DFC and the U.S. Department of Commerce loan facilities.

This government support shows that rare earth supply connects to industrial strategy and national security. Governments see critical mineral supply chains as essential for energy, advanced manufacturing, and defense. The deal’s financing reflects this change and improves the company’s financial outlook.

Significantly, USA Rare Earth (USAR stock) shares rose over 15% after the announcement, boosting the company’s market value to about $4.9 billion.

Overall, this acquisition marked a shift in how the Western rare earth industry approached supply security. Instead of relying on isolated mining projects, USA Rare Earth moved toward a fully integrated platform that connected mining, processing, metallization, and magnet manufacturing across multiple regions.

The deal strengthened access to heavy rare earths, improved supply chain control, and aligned closely with government-backed industrial strategy. While execution risks remained, the overall direction pointed clearly toward building a more secure and independent rare earth supply chain outside China.
