Air Quality Improvement Measures
Roadside emission reduction measures
1. motor vehicle emission control programme in 1999:
(a) replacing diesel taxis and light buses with liquefied petroleum gas (LPG) vehicles;
(b) introducing Euro III emission standards in tandem with the European Union (EU);
(c) retrofitting pre-Euro diesel vehicles with particulate traps or catalytic converters;
(d) deploying chassis dynamometers to test diesel vehicle smoke and taking stronger enforcement actions against smoky vehicles; and
(e) mandating ultra low sulphur diesel for vehicle use three years ahead of the EU.
2. starting from January 2007, all newly registered vehicles were required to comply with Euro IV emission standards;
3. since April 2007, all pre-Euro diesel vehicles have to be installed with approved emission reduction devices. The Air Pollution Control (Emission Reduction Devices for Vehicles) Regulation requires that these devices must be kept in good working condition for reducing particulate emissions. Owners of vehicles failing to comply with the requirements will have their vehicle licences cancelled or refused for renewal upon expiry;
4. launched on 1 April
5. starting from 1 April 2007, we offered a concession in first registration tax to encourage vehicle buyers to choose environment-friendly petrol private cars. The incentive scheme was terminated on 1 April 2015;
6. on 1 December 2007, the Government offered a concessionary duty rate of $0.56 per litre for Euro V diesel, which has a sulphur content of 0.001%. Since then, all petrol filling stations in
7. starting from 1 April 2008, the Government has been offering a concession in first registration tax to encourage the use of environment-friendly commercial vehicles;
8. launched on 1 July
9. tightened the mandatory specifications of motor vehicle diesel and unleaded petrol to Euro V standard from 1 July 2010. Euro V motor vehicle fuels contain 80% less sulphur content that Euro IV;
10. introduced on 1 July 2010, a regulatory control on motor vehicle biodiesel. The key elements of the regulatory control include biodiesel specifications and labelling requirements for selling motor vehicle biodiesel with biodiesel content over 5%;
11. starting from 18 June 2010, businesses which have purchased eligible environment-friendly vehicles may deduct the capital expenditure incurred under profits tax in the first year of the acquisition ;
12. enforcing since 15 December 2011 the Motor Vehicle Idling (Fixed Penalty) Ordinance to ban idling vehicles with running engines;
13. operating since March 2011 a Pilot Green Transport Fund to encourage the public transport sector and goods vehicle owners to test out green and innovative transport technologies;
14. starting from 31 December 2012, all newly registered vehicles are required to comply with Euro V emission standards;
15. phasing out some 82 000 pre-Euro IV diesel commercial vehicles through an incentive-cum-regulatory approach, and limiting the service life of diesel commercial vehicles newly registered on or after 1 February 2014 to 15 years;
16. fully subsidizing the franchised bus companies to retrofit selective catalytic reduction devices on Euro II and Euro III franchised buses, which could upgrade their emissions performance comparable to that of Euro IV or above level;
17. fully subsidizing the franchised bus companies to procure six double-deck hybrid buses and 36 single-deck electric buses for trial runs;
18. promoting the use of electric vehicles by various measures, such as waiving the first registration tax for electric vehicles and providing charging facilities and technical supports, etc. ; and
19. commenced in September 2014 a strengthen control of petrol and LPG vehicle emissions by using roadside remote sensing equipment and chassis dynamometer for emission testing.
Cutting emissions from power plants
20. prohibiting the installation of new coal-fired power plant since 1997.
21. imposing stringent emission caps on power plants since 2005 and stipulated the stringent emission caps for 2010 and beyond through a Technical Memorandum.
22. requiring power plants to regularly review and update their pollution control technology by the best practicable means.
23. providing power companies with incentive to reduce their emissions and to improve the air quality by introducing a mechanism in the Scheme of Control Agreements signed with the power companies on 7 January 2008 such that the permitted rate of return of the power companies is linked to their compliance with the emission caps.
Reducing emissions from industrial/commercial processes
24. amended the Air Pollution Control (Fuel Restriction) Regulation in 2008 to mandate the use of liquid fuel with sulphur content of not more than 0.005% by weight in the commercial and industrial sectors;
25. implementing since 1 April 2007 regulations to limit progressively the volatile organic compounds contents of certain products and mandate the installation of emission reduction device in certain printing machines. The regulated products now include paints, printing inks, selected consumer products, adhesives and sealants;
Controlling emissions from non-road mobile machinery
26. making preparations to require non-road mobile machinery newly supplied for local use to meet statutory emission limits on a par with those in Europe,
