Led by Singapore’s sovereign wealth fund, Temasek, through its investment arm GenZero, BeZero Carbon—a London-based carbon credit rating service—successfully raised $32 million in January 2025. This significant funding round, despite lingering doubts about the long-term viability of the sector, underscores Singapore’s ambition to become a global centre for credit trading, especially in the carbon market.
For Singaporean business owners, understanding the fundamental rules of credit trading, particularly carbon credit trading, is essential in today’s evolving regulatory landscape. This knowledge not only ensures compliance but also opens doors to new opportunities in sustainability and finance.
Grasping the Essentials of Carbon Credit Trading
At its core, carbon credit trading allows businesses to offset their greenhouse gas emissions by purchasing credits from projects that reduce or remove carbon dioxide from the atmosphere. Each carbon credit represents the reduction or removal of one metric tonne of CO₂ equivalent (CO₂e). By participating in credit trading, companies can effectively balance out their emissions, meeting regulatory requirements or voluntary sustainability goals.
Beyond compliance, credit trading offers a market-driven approach that incentivizes environmental innovation and conservation. Whether supporting renewable energy projects, reforestation, or carbon capture initiatives, these credits connect businesses with impactful climate action.
Carbon Tax and the International Carbon Credit (ICC) Framework
Singapore introduced its carbon tax in 2019 at an initial rate of S$5 per tonne of CO₂e emitted. The government plans to progressively increase this tax to S$25 per tonne in 2024 and potentially up to S$80 per tonne by 2030. This escalating tax highlights the growing importance of efficient credit trading strategies to manage financial exposure.
Complementing the carbon tax is Singapore’s International Carbon Credit (ICC) Framework, launched in January 2024. The ICC system permits companies subject to the carbon tax to offset up to 5% of their taxable emissions by purchasing approved overseas carbon credits. This mechanism integrates credit trading into Singapore’s broader environmental strategy, encouraging businesses to invest in credible and verified carbon reduction projects abroad.
To ensure integrity, the National Environment Agency (NEA) enforces stringent qualification criteria on eligible carbon credits. These include the principles of additionality (ensuring projects wouldn’t happen without the credit), permanence, and avoidance of double counting—critical factors that maintain the credibility of credit trading.
International Cooperation via Article 6 of the Paris Agreement
Singapore’s commitment to global climate efforts is further demonstrated through bilateral agreements under Article 6 of the Paris Agreement. Collaborations with countries such as Ghana and Papua New Guinea enable Singaporean businesses to participate in cross-border credit trading, buying carbon credits that support emission reductions both locally and internationally.
This framework promotes transparency and flexibility in the market, fostering trust in the validity of carbon credits traded. It also helps countries achieve their Nationally Determined Contributions (NDCs) more efficiently, creating a win-win situation for all parties engaged in credit trading
Tax Implications of Credit Trading in Singapore
Companies engaged in credit trading should be mindful of the associated tax consequences. The Inland Revenue Authority of Singapore (IRAS) classifies the issuance, transfer, and sale of carbon credits as “excluded transactions” for Goods and Services Tax (GST) purposes, meaning these transactions are exempt from GST.
However, profits made from trading carbon credits remain subject to corporate income tax. Therefore, businesses should carefully plan their credit trading activities with a clear understanding of both tax exemptions and obligations to optimize financial outcomes.
Building a Sustainable Business Model through Credit Trading
Beyond regulatory compliance, credit trading offers strategic advantages for companies aiming to enhance their sustainability credentials. Demonstrating leadership in environmental responsibility can improve brand reputation, attract eco-conscious customers, and secure investment from green-focused funds.
Singapore’s sophisticated regulatory framework, combined with its status as a financial hub, makes it an ideal base for enterprises exploring carbon markets and credit trading opportunities. The country’s robust infrastructure supports transparency and trust—critical ingredients for thriving in this complex sector.
For businesses new to credit trading or sustainability projects, professional guidance can be invaluable. Banks and financial institutions in Singapore often provide advisory services with dedicated sustainability financing teams. Engaging with these experts can help businesses identify qualifying carbon credit initiatives and navigate regulatory nuances effectively.
Singapore’s active role in promoting credit trading, supported by government policies, international agreements, and strong regulatory oversight, positions it as a leading global player in carbon markets. For business owners, embracing carbon credit trading is not only about compliance but also about unlocking innovative pathways towards sustainability and competitive advantage.
