Indicators and Objectives

In order to effectively manage PSMC's response to climate change, the Company has set various climate-related indicators to measure the effectiveness of climate actions, and through the TCFD governance framework, the Company has promoted the implementation of climate strategies, set climate-related objectives, adjusted them on a rolling basis in accordance with global trends and policies and regulations, and regularly reviewed the achievement of these objectives to continuously reduce the impact of climate change on the Company and enhance its resilience to climate change in the future.

TCFD Disclosure Content Promoted Strategy
Indicators used by the organization to assess climate related risks and opportunities in accordance with the strategy and risk management process
  • Establish greenhouse gas emissions, electricity consumption, renewable energy use, water recovery rate, etc. as indicators to measure climate-related risks and opportunities
Scope 1, Scope 2 and Scope 3 (if applicable) greenhouse gas emissions and associated risks
  • The plants of PSMC calculate the emissions and disclose the related data.
The objectives used by the organization to manage climate-related risks and opportunities, and the performance in achieving those objectives.
  • Climate related objectives are set, covering water resources, electricity, renewable energy, greenhouse gases, and waste.

 

Climate Related Aspects Indicators Objectives
