500 More Companies Face Mandatory Carbon Inventories, with 2030 Reduction Targets of up to 30%

Updated on October 6, 2026. This update covers the official announcement, annual registration rules and national emissions inventory data, linking inclusion rules with inventory tools.

Background: Emissions Reduction Pressures and Opportunities

As the global shift toward net-zero emissions accelerates, Taiwan's position in Asia's emissions reduction efforts becomes increasingly important. The Ministry of Environment's National Greenhouse Gas Inventory (2026 edition) shows that Taiwan's net greenhouse gas emissions in 2024 were 251.404 million metric tonnes CO₂e, down 6.59% from the 2005 baseline, but a long road remains to net zero by 2050. Compared with neighbouring Asian countries' targets, the Ministry's newly announced 2030 target of a 28% reduction from the 2005 baseline is second only to Japan's 41%, demonstrating regional ambition. It also sets an interim 2030 electricity emission factor target of 0.319 kg CO2e/kWh. However, amid intense regional competition on net zero, Taiwan must continue strengthening emissions reduction measures to consolidate its international position and sustainability commitments.

Policy Implications: The Rationale behind the Phase 3 Targets

The new 2030 emissions reduction target marks an important step under Taiwan's Climate Change Response Act. Progressively raising emissions reduction requirements not only demonstrates Taiwan's growing international standing but also brings policy pressure and opportunities for economic transformation across domestic sectors. Taiwan has announced NDC 3.0, setting reduction targets from 2005 levels of 28±2%, 32±2% and 38±2% for 2030, 2032 and 2035, respectively.

Looking Ahead: Overall Strategy and Key Impacts

As the net-zero deadline approaches, strengthening climate action to improve international competitiveness has become an unavoidable issue for government and industry. Expanded carbon inventory coverage is a key trend that all sectors need to watch closely, and the scope of regulated entities will inevitably expand further to meet the new reduction targets. By comparing international progress in economic growth and emissions reduction, this policy offers an important reference for future strategy and creates a new opportunity for Taiwanese companies to accelerate adjustments and respond to the opportunities and challenges of international emissions reduction rules.

Expanding Carbon Inventory Coverage to Meet the Targets

The figure above is from the policy planning presentation. Eligibility should be determined using the energy consumption, store count, vehicle count and hospital accreditation criteria in the official March 4, 2025 announcement, rather than estimated emissions tonnage alone.

The Ministry of Environment estimates that approximately 500 additional organisations are covered. Newly included entities must inventory Scopes 1 and 2, without verification. From 2026 onward, they must complete the inventory and registration of the preceding year's emissions by April 30 each year. For the full criteria, see Taiwan Expands Mandatory Carbon Inventories: Turning Challenges into Low-Carbon Transition Opportunities and the Ministry of Environment's official announcement.

How Should Companies Follow the New Carbon Inventory Rules?

On March 4, 2025, the Ministry of Environment announced the Emission Sources Subject to Business Greenhouse Gas Emissions Inventory and Registration, adding approximately 500 organisations. From 2026 onward, they must complete the inventory and registration of the preceding year's emissions by April 30 annually. Inventory guidance and calculators for four sectors are also available.

Establishing an annual inventory process based on the official announcement and guidance can reduce preparation pressure before each year's registration. We recommend starting organisational carbon inventory preparations in the following areas:

1. Identify emission sources: Understand direct and indirect carbon emission sources within the organisation and its supply chain.
2. Build a data foundation: Collect historical energy consumption data to provide a reliable basis for the carbon inventory.
3. Assign responsibilities: Identify the departments and staff responsible for carbon inventories to coordinate emissions data collection and management.

Digital carbon inventory tools will also become an essential choice for improving efficiency and addressing future emissions reduction needs. These tools help companies manage carbon emissions data conveniently, track it dynamically and generate reports quickly to meet annual inventory registration requirements. They also help analyse emission trends and develop more targeted reduction strategies, giving companies an advantage in emissions management.

Taking action early helps companies respond to regulations with greater confidence and lays a solid foundation for the future net-zero transition.
