Environment Protection


As a responsible corporate citizen, our Group has established policies and measures to minimise pollution, efficiently utilise energy, reduce waste and expand recycling in our operation. Risk-based thinking, life-cycle perspective and mitigation have been incorporated into our management system to address the latest environmental challenges. Our Group has established effective environmental management systems in compliance with internationally-recognised ISO 14001 and ISO 50001 standards. Adhering to the core values of the Group, we are members of various environmental groups and actively support these organisations.


Chun Wo’s environmental objectives are to prevent environmental pollution, reduce waste and enhance waste recycling from our operations.


1. Waste Management Hierarchy

Waste Management Hierarchy has been adopted on-site to reduce waste production and enhance recycling. Reusable wastes such as earth, broken concrete and temporary works are reused at other construction sites. Plastic wastes of expired safety helmets, damaged water barriers and traffic cones are recycled as plastic granules at EcoPark. Pressure on landfill disposal has been reduced through these measures.


Infrequent hazardous waste from demolition of old structures or equipment (e.g. asbestos), which accounted for less than 0.001% of the total waste generated, has been separated and treated in accordance with local regulations.


2. Initiatives for Managing Resources

The Group continuously manages its resources and energy use in an eco-friendly manner by:

.implementing Eco-Friendly Actions in our offices and project sites to promote environmental awareness;

.promoting the use of B5 bio-diesel with the aim of reducing carbon emission by 3%;

.managing fuel and electricity usage through deployment of high efficiency equipment;

.phasing out traditional T8 tubes and replacing with energy-saving T5 fluorescence tubes and LED lighting;

.using Lighting Management System (LMS) to control power voltage and save energy;

.reusing wastewater after sedimentation treatment for site cleaning, water suppression systems, wheel washing at site access, water barrier filling, etc.;

.reusing recycled water for preliminary air lifting of bore piles; and

.reusing water dripping from air-conditioners for roof sprinkler cooling systems and watering of plants.


The Group is committed to managing resources used in construction in order to maximise the benefits in environmental protection, energy efficiency and carbon footprint reduction.


Sustainability designs and construction methods have been initiated in our project sites with developed mitigation measures to protect our environment, reduce waste generation and enhance recycling. In one of our projects, namely Water Resources Education Centre of Water Supplies Department of the Hong Kong government, the Zero Dust Grouting System is introduced to minimise dust generation on-site. Building Information Modelling has been also applied to accurately predict construction process aiming to reduce excavation and lateral support waste materials. The waste materials are recycled as ecological bricks for use at other construction sites. In addition, as the project site is located along the flight path of wetland birds of Deep Bay, the site office is protected by high frequency devices with artworks of birds of prey on top of the office, maintaining sustainability of the environment.


3. Carbon Audit

Our Group has extended the carbon emission monitoring system from the head offices to project sites since 2004. Eco-Friendly Actions, such as paperless meetings, switching off lighting and appliances (computers and monitors) during lunch hours and maintaining indoor temperature at 24.5˚C, have also been implemented at offices and construction sites to enhance staff’s environmental awareness for reducing energy consumption and carbon emissions. We also support eco-renovation by applying energy-saving lighting, utilising natural light in interior design and reusing old furniture.


Carbon audit has been conducted at various offices and construction sites in 2016, identifying carbon emission inventory, waste reused and recycled procedures. Our Group has begun to establish a comprehensive group-wide carbon audit system which further extends the existing scope to monitor emission data of the different business units under our Group in 2017.


In 2016, our Company and Chun Wo have been awarded the CarbonCare® ESG Label and CarbonCare® Action Label respectively by CarbonCare InnoLab, recognising our achievement in adopting innovative carbon reduction solutions and high standards of ESG reporting.
