Infrastructure

To save energy, escalator, lighting and air-conditioning in some parts of the Hong Kong Convention and Exhibition Centre are adjusted or switched off according to usage rates

Employs advance precast construction technology to reduce noise pollution, air pollution and building wastes like bamboo
Provides environmental mitigation facilities including wastewater treatment plant, wheel washing machine, noise barrier and automatic mechanical cover for trucks to minimize environmental impact arising from its building work
Reuses and recycles construction wastes like timber and metal on its sites

Young's Eng. Co Ltd., Majestic Eng. Co. Ltd., Far East Eng. Services Ltd. and Joneson Chemical Engineers Co. Ltd. under NWS Engineering Group Limited have achieved the ISO 14001 accreditation by HKQAA since 2001 in different phases, signifying their Environmental Management Systems comply with the international standard
Controls the use of ductile iron pipe and lubricant to avoid pollution and wastage of material; reuses all lubricants discharged during the process
Checks operation vehicles every six months and uses environmental friendly diesel to reduce and control their pollutant emission

Adopts environmental friendly design in vessels including:
- Tinted glass panel in cabin, which reduces light and heat from the sun, thus reducing demand for air conditioning in summer and energy consumption
- Non-toxic anti-fouling paint on bottom hull containing no Tributyl tin (TBT) which is toxic to marine life. The paint coating's self-polishing and smoothing mechanisms prevent organisms such as barnacles and weed from building up on the underwater hull and reduces resistance, hence help save fuel and reduce emission.
- Environmentally-friendly engine which complies with the International Maritime Organization's "Regulation For The Preventing Of Air Pollution From Ships". It is fitted with electronic control and fuel-oil-common-rail systems which achieve significant reduction of soot emission at low engine speeds and low fuel consumption over the entire performance range.

Launch Blue Sky Plan which includes the purchase of new Euro IV green buses, speeding up the retirement of pre-Euro and Euro I buses proactively, and installing Diesel Particulate Filter on Euro II buses to improve emissions
Use ultra low sulphur diesel in the whole fleet and check emissions regularly to improve and control emissions
Adopt the Pozilock refuelling system with auto-lock that prevents spillage of diesel and reduces wastage
Treat and recycle 70% of water used in bus washing
Retread around 8,000 used tyres every year to extend the life of a bus tyre from seven months to two years; recycle scrapped tyres and fluorescent tubes
Implement waste treatment system in which waste oil is stored at centralized tanks by pipe-work and collected by an oil recycler; install pre-treatment facilities in depots to minimize environmental impact of wastes arising from operation
Adopt eco-friendly operation management: committed to deploying eco-friendly buses to serve busy urban areas; Bus-Bus Interchange discount schemes and rationalisation of bus routes and stops are implemented to reduce the number of bus trips passing through busy districts; Provide comprehensive training courses to indoctrinate bus captains the "safe, comfort and eco-friendly" driving skills with proper driving manners
