Deterioration of air quality in PRD Region

As Ozone level continues to break record high

And level of Nitrogen Dioxide and Particulate Matters cease to drop

 

It is worrying to observe the worsening of Ozone level and the lack of improvement of other key pollutants including the Nitrogen Dioxide and the Particulate Matters. With a massive population in the super-region, the deterioration of the air quality is a strong public health issue.

The “Outline Development Plan for the Guangdong-Hong Kong-Macao Greater Bay Area“, published in 2019, pledged to “pursue green development and ecological conservation” as one of the six basic principles. Clean Air Network urges the Guangdong and HKSAR Governments to establish a stringent post-2020 regional emission reduction targets with a view to maximize public health gain. 

 

Ozone

The level of Ozone reached a 14-year record high according to the official data. Clean Air Network has alerted the worsening trend of Ozone in HKSAR in recent years but it was disappointing not to see specific action from the Government. We urge the Guangdong and HKSAR Governments to complete the study “Characterisation of photochemical ozone pollution in the Greater Bay Area and its regional and super-regional transportation” as soon as possible and propose policy measures to minimise worsening of ozone within 3 years.

 

Nitrogen Dioxide and Particulate Matters

Meanwhile, since 2014, the concentration level of other pollutants, including the respirable suspended particulates (PM10), fine suspended particulates (PM2.5) and nitrogen dioxide (NO2) has improved for the past consecutive years.

However, in 2019, it ceased to see any improvement of these 3 pollutants and NO2 has even worsened (compared to 2018). This regional trend is similar to the local (HKSAR) trend observed over the past few years since the launch of the Clean Air Plan for Hong Kong published by the Environment Bureau of HKSAR Government. It is possible that the effect of the policy measures imposed over the past few years were neutralised by the worsening pollution sources (such as, growth of number of road vehicles, ageing of vehicular fleet). The Clean Air Plan will be expired by end of 2020 and there is no news of when the HKSAR Government will update it.

 

ABOUT CLEAN AIR NETWORK

Established in 2009, Clean Air Network is a non-profit organization with charitable status which envisions to clean up Hong Kong’s air until it meets the World Health Organization’s recommended safe level. Our mission is to amplify the voices of individuals, groups and organizations and together urge the Government to take appropriate measures to clean air.
