Greenhouse Gas Management

For corporate risks arising from global warming, CHC Group has taken prompt actions to incorporate climate issues into strategy formulation and management decision-making across all aspects of operations. In line with the industrial characteristics and business models of each business entity, the Group sets respective annual goals, formulates greenhouse gas management plans and ensures continuous management and improvement. The management strategies include, but are not limited to, establishing a mechanism for quantifying greenhouse gas emissions, researching carbon reduction solutions, investing in renewable energy development, and enhancing energy management efficiency.

In order to monitor greenhouse gas emissions and align with the “Sustainable Development Roadmap for Listed Companies,” the CHC Group plans to complete the boundary verification of consolidated financial statements in 2026. Starting from 2021, the Group has gradually implemented the ISO 14064-1:2018 greenhouse gas inventory standards in phases. By the end of 2024, the greenhouse gas inventory for 2023 of CHC (standalone), CCLC (standalone), CEC (standalone), CDC (standalone), and HDEC (consolidated) have been verified by Bureau Veritas Certification (BV) and obtained the ISO 14064-1:2018 greenhouse gas verification statement. In the first quarter of 2025, the greenhouse gas verification for 2024 of CHC (standalone) and CCLC (standalone) have been verified by Bureau Veritas Certification (BV), while the greenhouse gas emission data for 2024 of the other companies/locations within the Group is currently undergoing third-party verification.

CHC will continue to enhance its greenhouse gas emission management approaches and strengthen the carbon reduction policies and action plans of its business entities, in an effort to mitigate and adapt to the impacts of climate change as well as to achieve the goal of low carbon operations.

Greenhouse Gas Emissions

Aiming at proactively reducing greenhouse gas emissions, CHC Group regularly reviews the usage of various energy sources and the emission of greenhouse gases in order to have in-depth knowledge of the overall emission trends and energy efficiency and use them as a basis for the management of greenhouse gas emissions and development of action plans.

Scope 1 and Scope 2

In 2024, the operational scale of the CHC Group continues to expand. The total greenhouse gas emissions for Scope 1 and Scope 2 amounted to 61,387.06 metric tons CO₂e, representing an increase of 0.6% compared to the previous year. Combined Scope 1 and Scope 2 emissions in 2024 amounted to approximately 2 metric tons CO₂e per million dollars of revenue, a 0.5% increase from 1.99 metric tons CO₂e per million dollars in the previous year.

The total greenhouse gas emissions from Scope 1 and Scope 2 for CHC Group primarily arise from electricity consumption associated with water treatment processes. Consequently, electricity consumption per ton of wastewater treated and reclaimed water supplied has been established as a quantitative management indicator. Through energy-saving initiatives such as optimizing high-energy-consuming equipment, implementing smart energy management systems, and enhancing operational practices, we aim to enhance the efficiency of water resource treatment. In 2024, the electricity consumption per ton of wastewater treatment was 0.33 kWh, representing an 11% improvement over the established target.
