Regulatory Update: What Your Business Should Know About Singapore's ICC Eligibility List

January 4, 2024


In October 2023, we published a blog breaking down the Singapore government’s Eligibility Criteria under the International Carbon Credit (ICC) Framework, which is a list of seven principles that ICCs must meet to be surrendered for the carbon tax. In our latest blog post, we explore key details of the recently released Eligibility List under the ICC Framework, which went into effect on January 1, 2024. This significant update by the Ministry of Sustainability and the Environment (MSE) and the National Environment Agency (NEA) will shape the way businesses approach their sustainability goals in 2024 and beyond.

Singapore’s carbon tax policy: A refresher

On January 1st, 2019, Singapore implemented a carbon tax of $5 per metric ton of carbon dioxide equivalent. This was the first carbon pricing scheme in Southeast Asia. In March 2022, the government announced that it would be progressively increasing the carbon tax as part of raising its climate ambition to encourage businesses and individuals to reduce their carbon footprint. The carbon tax will be raised to $25 per ton in 2024 and 2025 and $45 per ton in 2026 and 2027, with the eventual aim of reaching $50 to $80 per ton by 2030. [1]

How are carbon credits related to the carbon tax, and which carbon credits are eligible?

From 2024, companies will be able to surrender high-quality international carbon credits to offset up to 5% of their taxable emissions. The Singapore government has released the Eligibility List, which outlines the eligible carbon credits that companies may use to offset part of their liability under the Singapore carbon tax. [2]

Why is this significant?

Since the announcement of the tax increase, companies have been awaiting more direction from the government on eligible carbon credits. The Eligibility List illustrates the eligible host countries, carbon crediting programs, and methodologies that adhere to the Eligibility Criteria. The National Environment Agency (NEA) - the administrator of the carbon tax regime - will review and update the Eligibility List every year to ensure relevance and adherence to high environmental integrity standards, guided by the latest science and evidence. This will include adding or removing carbon crediting programs and methodologies from the list. [2]

Additionally, the Eligibility Criteria will also be reviewed periodically to ensure alignment with developments in both Article 6 of the Paris Agreement and the carbon markets. [3]

Breaking down the most important points from the Eligibility List

Eligible carbon crediting programs and methodologies may differ based on the host country, as each host country has its own criteria. The Eligibility List for each host country would be agreed under the respective Implementation Agreement, which outlines the processes for generating and transferring international carbon credits aligned with Article 6.

Notably, Papua New Guinea was the sole host country on the latest version of the Eligibility List, with four carbon crediting programs approved for the country: the American Carbon Registry (ACR), Global Carbon Council, Gold Standard for the Global Goals, and the Verified Carbon Standard (VCS).

For Papua New Guinea, the eligible methodologies include all active ones published before March 31st, 2023, with certain exclusions for each carbon crediting program. For example, under the VCS, methodologies under the “Sectoral Scope 14” category (Agriculture, Forestry, and Other and Use (AFOLU)) are not accepted. However, there are a few allowable exceptions to this exclusion, such as tidal wetland and seagrass restoration, improved agricultural land management, and sustainable grassland management. [2]

In the meantime, Singapore continues to work towards signing Implementation Agreements with countries such as Bhutan, Cambodia, Chile, Colombia, Costa Rica, Dominican Republic, Fiji, Ghana, Indonesia, Kenya, Mongolia, Morocco, Paraguay, Peru, Rwanda, Senegal, Sri Lanka, and Vietnam. [4]
