Environmental Performance

We strive to apply innovative solutions and initiatives to our services and operations as we reduce greenhouse gas emissions, waste, and the consumption of resources, from energy to water in accordance with our Sustainability Policy. We take into account local environmental laws and regulations wherever we operate, and endeavour to go beyond regulatory compliance and consistently benchmark ourselves against local and international standards and best practices. This ensures we are well positioned to continually enhance our environmental performance.

Climate Change

Our Approach

We are committed to playing our part to tackle climate change. Our Climate Change Policy established in 2020 outlines our commitment by means of managing climate risks across our business strategy and operations.

Carbon Emissions and Energy Consumption

We are committed to reducing our energy and carbon footprint, and continues to identify ways to achieve this. Energy consumption is the prime source of our greenhouse gas emissions; each of our business units works towards a common goal of developing their own guidelines and plans to reduce energy consumption year on year. In practice, our energy-reduction initiatives are two-fold; we promote the use of energy-efficient equipment and installation, while considering day-to-day business functions and employee behaviour to identify areas for improvement.

Key Initiatives

  • Climate Change Policy established (along with Sustainability Policy)
  • Set climate related targets: Carbon and Energy intensity reduction of 50% by 2030
  • Climate scenario planning study piloted to assess physical risks for HKCEC
  • Signatory of Business Environment Council (BEC) Low Carbon Charter
  • BEC Climate Change Business Forum Advisory Group – Steering Committee member
  • Issued first Sustainability Linked Loan amounting to HK$1 billion
  • As an investor, we are committed to:
    - Progressively phasing out investments relating to coal fired power
    - Adopting ESG considerations for future investments
    - Investing in infrastructure and service businesses that enhance lives

Environmental Management

Formed by representatives from our subsidiary companies and chaired by an Executive Director, our Environmental Management Committee meets twice a year and provides a platform for the development and implementation of green initiatives, and the exchange of knowledge, experience and environmental best practices among business units. We review any previous cases of non-compliance, litigation and summons to identify risks related to environmental issues, and work out the best remedial measures available.


Air emissions are a significant issue for the roads and construction industries. Although our highway operation business is not a direct contributor to road emissions, we support nation-wide objective to enhance air quality. We consistently develop innovative solutions, such as Venturi Cyclone at our construction sites to reduce air emissions from generator sets, and ensure proper environmental site management is in place.


We strive to reduce our energy consumption and invest in energy-efficient technologies. In addition to the initiatives for reducing air emissions by reducing fuel consumption, we actively seek for opportunities to expand our adoption of clean energy in our daily operations, such as the installation of solar panels at several business sites and providing on-shore power supply at various piers.


Water plays an important role in our operations and we are committed to using it efficiently. We have a range of water-saving initiatives across our businesses with different focuses to address various operation nature.


Addressing specific waste issues requires practical steps adapted to the nature of work of each business unit. We use resources on a needs-only basis to minimise hazardous wastes, and try to reuse and recycle non-hazardous wastes where practical. To fulfil our commitment to minimising waste, we introduce a range of initiatives, including internal activities and external campaigns, to encourage communities and our stakeholders to join us on our sustainability journey.


While direct impacts on biodiversity are not recognized as a material issue among our business operations, we practice biodiversity conservation where appropriate. We are committed to minimizing the potential adverse impacts of our operations on biodiversity through, for example, adopting recognized standards and certificates for more sustainable use of natural resources, e.g., Forest Stewardship Council (FSC) and Programme for the Endorsement of Forest Certification (PEFC) where possible; minimizing habitat disturbance, degradation and indirect effects of operations; and promoting the awareness of biodiversity among our stakeholders such as employees and the community.

Enhancing Marine Biodiversity through Oyster Reef Restoration


Enhancing Marine Biodiversity through Oyster Reef Restoration

Deep Bay in Hong Kong is largely enclosed by land and is lined by wetland of marches. The margin of fresh water and salt water forms a valuable habitat for a wide variety of marine life. Led by The Nature Conservancy, NWS’ volunteers helped reconfigured abandoned oyster farms into more natural shellfish reefs, with aim to enhance marine ecosystem protection and restore habitats for species to forage in the area.

Tree conservation at Queen’s Hill Public Housing Construction project

One of the tree protection measures in construction is through transplanting trees with carefully designed procedures to ensure their proper growth at the temporary and/ or permanent receptor site.
Sustainability-linked Loan


Sustainability-linked Loan

In June 2020, we announced our first sustainability-linked loan with Crédit Agricole Corporate and Investment Bank. The loan is converted from existing financial facilities amounting to HK$1 billion, of which interest rates will be reduced according to our improvement on environmental and social targets, including greenhouse gas emission intensity and continual improvement on the overall Labour Practice criteria in accordance with the Hang Seng Corporate Sustainability Benchmark Index. This sustainability-linked loan reinforces our commitment to improving our sustainability performance, as well as demonstrating the financial incentives for continual improvements.
Renewable Energy


Renewable Energy

Throughout our operations, we have also adopted the use of renewable, zero-emissions energy sources where practical, such as solar panels. Sites including the HKCEC, have solar panels installed on their rooftops, supplying renewable energy to the local power grid to take advantage of the Feed-In Tariff Scheme in Hong Kong. During FY2020, the total renewable energy generated for the Feed-In Tariff Scheme on our premises was over 59,000 kWh (214 GJ), avoiding around 30 tonnes of carbon emissions, which is equivalent to the annual emissions from six passenger vehicles.
Improve Roadside Air Quality by Technological Upgrade


Improve Roadside Air Quality by Technological Upgrade

Hangzhou Ring Road has adopted a series of technological upgrades to enhance the operations of the 103.4 km toll road – as part of the Hangzhou City Brain 2.0 project, launched by Hangzhou City Government and Alibaba Group in 2016. The upgrades include real-time automated monitoring, intelligent dispatch, and vehicle management.

Through the integrated use of surveillance footage and big data technology, real-time analysis of all vehicles running along the entire toll road can be performed. The system is capable of quickly identifying situations which may interrupt traffic flow, such as vehicles stopping illegally, vehicle breakdowns and trespassing pedestrians. The automated system can spot anomalies within one second and raise alerts within 10 seconds of incidents, a significant improvement on the manual inspection of over 300 surveillance footages, which can take more than one hour.

Optimizing traffic flow provides multiple benefits. Timely response to road incidents can significantly reduce traffic congestion, which also translates to reduce greenhouse gas and air emissions. The less time spent in congested traffic, the less users are exposed to air pollutants, translating into positive impacts for their physical health and well-being. Furthermore, enhancements to traffic flow improve revenue stability for the toll road, and contribute to the overall efficiency of the city. This provides a great example of our pursuit of shared value creation, bringing about a triple-win situation for the customers, the environment, and our business.
