Adapting to Environmental Changes

The Task Force on Climate-related Financial Disclosure (TCFD) was set up by the Financial Stability Board (FSB) in December 2015 to develop beneficial solutions and make climate-related disclosures. Its primary role is to provide a clear, efficient and voluntary disclosure framework, and help enterprises in climate-related financial disclosures and in communicating to the users. By introducing the TCFD framework and taking the physics, responsibilities, and transformation risks into account, CTCI will evaluate the climate change risks that value chain partners, suppliers, and CTCI itself encounter. It will accelerate the promotion of CTCI's climate-related financial disclosures and facilitate communication with stakeholders.

Greenhouse Gas (GHG) Emission Investigation

CTCI was required by CDP investors to fill out the climate change project questionnaire and obtained the great results of management level B for two consecutive years. We implement the procedure recommended in the questionnaire every year to review our gaps in climate change management to make improvements to related issues and make it useful.

Note 1:The target is no more than the average of the previous two years.

Note 2:The construction sites include both domestic and foreign sites.

Note 3:Inventory methods include ISO 14064-1, the GHG Protocol─A Corporate Accounting and Reporting Standard, GHG Inventory Registry Guidelines; 2013 IPCC AR5 is adopted for GWP value; EPA's GHG Emission Factor Management Table v. 6.0.3 is adopted.

Note 4:The scope in 2018 has been extended to foreign countries, so the emissions have increased significantly.
