MTR Corporation Limited

A large-scale chiller replacement project has been carried out at stations and depots, with an aim to reduce electricity consumption by up to 30% compared to 2017. We also continue to replace lighting into LED at our stations and trains and review our operating procedures to further optimise our energy efficiency. In Hong Kong, we have adopted regenerative braking technology to convert kinetic energy produced during train braking to electrical energy which is then fed back into the power supply network for use by other trains.

Replacement of traditional lights with LED lights; Installation of high energy efficient air conditioning systems for plant rooms, common areas and main lobbies, and installation of variable speed drive (“VSD”) at the ventilation fans of air handling units; Installation of motion and optical sensor-controlled lighting with a dimming function for rear staircases and mechanical floors;

In 2020, we put in place a Sustainable Finance Framework to cover a wider range of financing transactions where the proceeds are used for furthering the development of sustainable urban infrastructure in support of the United Nations Sustainable Development Goals. The Sustainable Finance Framework sets out how we use the proceeds to fund initiatives to enhance long-term service levels and environmental and social performance, as well as the reporting thereon.

We have placed three-colour recycling bins in the concourse of all MTR stations for collecting recyclables such as paper, cans and plastic bottles. We have also been installing free drinking water dispensers and water vending machines at different MTR stations to encourage passengers to use refillable drinking bottles and hence to reduce the use of single-use plastic containers. In our managed properties, we proactively seek opportunities to enhance the public awareness of proper waste management and work closely with the Owners’ Committees and Incorporated Owners to promote different source separation of waste programmes to residents.

A variety of recyclables such as used papers, used clothes, glass bottles are being collected. We also collect glass bottles for the “Glass to Brick” programme to produce reusable material.

Clean and renewable energy has been adopted as part of our carbon reduction strategy. For example, solar system has been installed in Hin Keng Station to support the operation of station facilities. Other locations, such as Pat Heung Depot, Chai Wan Depot, Sunny Bay Station and Siu Hong Station have also been identified for the installation of more solar energy projects systems.

In addition, we continue to explore possible measures to lower carbon emissions of our feeder bus fleet, such as electric bus.

Modernisation of lift and escalator; Upgrade of Building Management System; and Installation of Sun Control Window Films at Clubhouse.

In our stations, we have concentrated our efforts to improve energy efficiency of our indoor environmental controls, whilst maintaining a comfortable temperature for our customers and staff. For instance, we have installed variable speed drives (“VSD”) on the ventilation fans of air handling units at some of our stations. The VSD reduces the speeds of ventilation fans when the carbon dioxide level in the station is low, thus reducing their energy consumption.

In addition to safeguarding passengers, our platform screen doors help preserve the ambient temperature by reducing the piston effect where moving trains push hot air into the station and pull cool air into the tunnels.
