The Clean Air Act outlines the government’s measures to reduce air pollution and incorporate environmental protection into its developement plans. It relies heavily on the polluter pays principle and other market-based instruments to promote self-regulation among the population. It sets emission standards for all motor vehicles and issues registration only upon demonstration of compliance. It also issues pollutant limitations for industry. Polluting vehicles and industrial processes must pay a charge. Any individual, enterprise, corporation or groups that installed pollution control devices or retrofitted its existing facilities to comply with the emissions standards in the Act can apply for tax incentives of accelerated depreciation, deductibility of R&D expenditures or tax credits on the VAT of the equipment and are exempt from real property tax on the machinery or equipment used to comply. It also establishes a R&D program for air pollution reduction mechanisms and technologies. It bans incineration and smoking in public places. At the local and municipal levels, governments are allowed to set emission quotas by pollution source, and the development of recycling programs is encouraged.
