Companies in Singapore will have to meet tougher emission standards for a wide range of pollutants from July this year, to help improve the country's air quality.
Announcing the new guidelines yesterday, the National Environment Agency (NEA) said the pollutants include mercury, cadmium, ammonia, lead, carbon monoxide, nitrogen oxides and particulate matter.
From July, new industrial plants will have to comply with the higher standards.
Existing plants have until July 1, 2018 to meet some of the guidelines, and until July 1, 2023 for the rest.
The NEA said: "The introduction of the more stringent standards will serve to improve our air quality as we strive towards achieving our air quality goals for 2020 and beyond."
It added that it had been in consultation with affected firms since early last year, and the grace period will give them time to adjust.
For example, they can upgrade their equipment.
Tightening the standards will encourage firms to continually review and improve their operations.
It is also in line with the Government's goal of growing industries here sustainably in the long term.
The NEA also introduced a daily limit for sulphur dioxide emissions from combustion sources, since industrial activity makes up 99 per cent of the emissions generated locally.
In 2012, motor vehicles made up the remaining 1 per cent, according to statistics on the NEA's website.
Last year, the Republic's sulphur dioxide, fine particulate matter, particulate matter and ozone emissions all exceeded World Health Organisation guidelines.
Emissions here, however, are affected by haze from neighbouring countries.
