As global sustainability regulations continue to tighten, carbon fees, carbon taxes, green subsidies, and tax incentives have become more than just environmental issues—they are now central to corporate strategy and financial planning.
Traditionally, tax management focused on minimizing tax liabilities and ensuring compliance. However, in the era of net-zero and responsible investing, taxation is no longer merely a cost—it has become a powerful lever to support ESG goals.
This article explores three key areas: understanding the difference between carbon fees and carbon taxes, making the most of tax incentives, and leveraging green subsidies and financing, to help companies manage tax costs effectively while advancing sustainability and creating financial value.

1.Why Should ESG Incorporate Tax Perspectives?
When planning ESG strategies, many companies focus on disclosure, goal setting, and action plans, but often overlook the role of taxation in sustainable governance. In reality, the connection between tax and ESG lies in two key areas: costs and incentives.
1.1 Increasing Environmental Tax Burdens
As countries pursue net-zero goals, many have introduced carbon pricing mechanisms—such as carbon taxes, carbon fees, and emissions trading—to turn carbon emissions into measurable costs.
For businesses, this means that failing to control emissions not only weakens competitiveness but also exposes them to significant tax pressure.
For example, Taiwan’s upcoming carbon fee, and existing carbon tax systems in Japan, Singapore, and Sweden, are expected to significantly increase operating costs.

1.2 Emergence of Policy Incentives
Alongside cost increases, governments are also introducing incentives—such as green investment deductions, energy efficiency subsidies, and enhanced R&D tax credits—to encourage corporate transformation.
For instance, the U.S. Inflation Reduction Act (IRA) includes tens of billions of dollars in tax breaks and subsidies. If companies can assess their emissions early, understand policy trends, and utilize tax tools effectively, they can not only mitigate risks but also build a competitive edge.

2. Carbon Fees vs. Carbon Taxes: Different Characteristics and Responses
2.1 What is a Carbon Tax?
A carbon tax is a government-imposed levy established by tax law, aimed at supplementing public finances and influencing behavior. Its key features include:
- High rigidity, fixed tax rates, and no exemptions
- Revenue goes directly into the national treasury without earmarked use
- Cannot be offset against carbon reduction obligations
Carbon taxes are commonly seen in countries like Sweden, Singapore, and Japan. For companies, responding to carbon taxes requires improving energy efficiency and investing in low-carbon technologies to reduce emissions.
2.2 What is a Carbon Fee?
A carbon fee is more akin to an administrative charge and functions as a policy tool for regulation and guidance. Key features include:
- Collected by competent authorities, with revenue often allocated to emission reduction projects or technology R&D
- Greater flexibility, with rates adjustable based on policy
- Some countries allow exemptions or offsets
Taiwan currently adopts a carbon fee model, collected by the Environmental Protection Administration, with revenues reinvested in domestic emission reduction initiatives.
2.3 Recommended Actions
Companies should first identify which system and calculation methods apply to them. Then, they should establish a carbon inventory framework and assess the financial impact under future scenarios. Suggested steps include:
- Replacing energy-intensive equipment and adopting energy-saving technologies
- Purchasing renewable energy certificates or participating in national carbon reduction projects
- Planning long-term carbon management strategies to avoid unnecessary carbon tax and fee expenses
3. Reducing Transition Costs Through Tax Incentives
For many companies, sustainable transformation is often perceived as costly. However, by leveraging tax incentive policies, businesses can significantly reduce financial pressure and improve return on investment.
3.1 Common Tax Incentive Tools
- Green Investment Deductions
Investments in renewable energy infrastructure, energy-efficient equipment, electric vehicles, and green buildings may qualify for investment tax credits or accelerated depreciation. - Enhanced R&D Deductions
R&D expenses related to low-carbon technologies and eco-friendly products may be eligible for high-percentage additional deductions. - Green Building Incentives
Constructing office spaces or factories that meet green building standards may lead to reductions in property and land taxes.
3.2 International Example
The U.S. Inflation Reduction Act (IRA) offers extensive tax breaks, cash subsidies, and loan support, making it a valuable reference for companies developing sustainability strategies. Businesses should regularly monitor policy developments domestically and internationally and work with tax advisors to design strategies tailored to their growth plans.

4. Leveraging Green Subsidies and Sustainable Financing Opportunities
4.1 Green Subsidy Programs
- Energy-Efficient Equipment Subsidies
Support for companies to upgrade high-energy-consuming facilities such as air conditioning, lighting, motors, and process equipment. - Electric Vehicle Subsidies
Covers electric cars, buses, logistics vehicles, and related charging infrastructure. - Carbon Inventory and Certification Grants
Funding assistance for companies conducting greenhouse gas inventories and obtaining certifications such as ISO 14064 or product carbon footprint labels.
4.2 Sustainable Financing Options
For larger-scale funding needs, companies may consider the following financial instruments:
- Green Bonds
Funds raised are earmarked for green projects that meet specific criteria, such as renewable energy, energy efficiency, and pollution control. - Sustainability-Linked Loans
Loan terms are tied to the company’s ESG performance indicators, with preferential interest rates granted upon achieving set targets.
5. Conclusion: Integrating Tax and ESG—Early Planning is Key
ESG is not just about carbon reduction—it is a long-term governance strategy that involves navigating taxes, resources, and markets. As ESG becomes a market norm, tax departments must evolve from passive reporting units to active drivers of sustainability strategy. Companies should proactively assess their emissions and tax burdens, simulate policy scenarios, leverage tax incentives, subsidies, and financing tools, and integrate these into financial planning to ensure sustainability actions are measurable, traceable, and verifiable.
By aligning tax strategy with ESG, businesses can not only reduce risks and stabilize cash flow but also build trust with investors and supply chains—emerging as leaders in the sustainability race.
