As a low-carbon public transport provider, we are committed to managing our environmental footprint and achieving carbon neutrality. Our Corporate Responsibility (“CoR”) Policy highlights our commitment to manage and mitigate environmental impacts of our business taking into account resource use, biodiversity and climate change. The CoR Policy lays down a solid foundation to incorporate sustainability considerations into the entire lifecycle of our projects and operations. To supplement the CoR Policy, we have established a Green Procurement Policy covering specific supply chain-related aspects and a Climate Change Strategy to stipulate our commitment to mitigating, adapting and building resilience to climate change.


We recognise climate change as a highly material issue to our business, bringing both risks and opportunities to our existing operations as well as future development. Our commitment to addressing climate change is demonstrated by our support of the Government’s Hong Kong Climate Action Plan 2050 which outlines strategies and targets for combating climate change and achieving carbon neutrality by 2050. We also support the International Association of Public Transport (“UITP”) Declaration on Climate Leadership which spells out the industry’s responsibility to act and its commitment to climate leadership. Our Climate Change Strategy emphasises our commitment to managing and minimising our impacts on climate change through mitigation, adaptation and building our climate resilience.


We have developed a long-term decarbonisation roadmap for the operation and development of our railway and property businesses in Hong Kong through conducting a carbon reduction study in which we took into account a comprehensive range of factors including the latest climate science, technology trends, Hong Kong’s Climate Action Plan 2050, and the risks and opportunities for our business. Following the Study, we are committed to setting science-based carbon reduction targets for the operation and development of our railway network and property portfolio in Hong Kong for 2030 with the longer-term goal of achieving carbon neutrality by 2050.

In 2020, we started to communicate our climate-related policies and strategies, especially those related to financial disclosures, with reference to the recommendations of the Task Force on Climate-related Financial Disclosures (“TCFD”) to provide our stakeholders with comparable and consistent information on how the Corporation is tackling climate change and managing the associated risks and opportunities.
