Environmental Policy
Our Environmental Commitment
Since 2020, Jioushun has maintained a formal Environmental Policy grounded in six core principles. These principles guide every construction project, office operation, and procurement decision we make — reflecting our responsibility to the planet, our communities, and future generations.
Climate Risk Management — TCFD
Jioushun has adopted the Task Force on Climate-related Financial Disclosures (TCFD) framework to identify, assess, and manage climate-related risks and opportunities. The General Manager’s Office serves as the highest responsible unit for climate risk management, integrating climate considerations into our Sustainability Development Working Group.
We established the Sustainability Development Working Group in 2023, with annual meetings to set targets and review progress. In 2026, a Board-level Sustainability Development Committee was established. Climate risk findings are reported to the Board.
