ENN Energy Holdings Limited is committed to environmental sustainability. By identifying the risks and opportunities posed by climate change, we take timely responses to adapt or mitigate the impact of climate change on business.  

ENN Energy formulated the ENN Energy’s Climate Change Policy, which  clarifies the company’s climate change targets and risk response. It is used as the basis to respond to climate risks, take advantage of the opportunities arising from climate change, and contribute to the mitigation of global climate issues.

The ESG Committee maintains oversight over climate change-related issues, regularly discusses and monitors climate risks through actions including:

1. Identifying the company’s climate risks and opportunities of climate, assessing the thus to set climate goals;

2. Assessing the impact of potential extreme weather and natural disasters on gas transmission and distribution, pipeline network storage, transportation, and safety, and formulating timely response strategies.

To guarantee the effectiveness of climate risk management and governance, the company incorporates performance indicators of climate risk management into management's remuneration with appropriate implementation and supervision of related activities through the establishment of a management team dedicated to climate change response.

Climate Stategy

Following the guidance of climate change management framework, ENN Energy has developed relevant business strategies to mitigate potential climate risks, while seizing opportunities of low-carbon transformation and benefiting the cooperation with stakeholders. We forwardly work with the government to carry out “goal-to-gas” and promote zero-carbon energy development. Solar energy, geothermal energy, biomass energy, and hydrogen are developed as the green energy business.

limate Risk Identification and Response

With preliminary review and analysis of the climate risk levels of operation area, we have identified significant climate-related matters that have had or are likely to have impacts on ENN Energy, and have formed risk identification results by region (see pages 13-15 of the ENN Energy 2020 ESG Report for details).  

In 2020, we had identified the transition risks and physical risks related to climate change, and finally formulate corresponding countermeasures. At the same time, we have referred to the Climate-Related Financial Disclosure Task Force (TCFD) framework to disclose climate-related governance, risks, strategies and objectives.
