Based on the criteria of Waste and Circular Economy, HK has been investing in facilities (e.g EcoPark) and technology that allows for efficient resource use and less waste.
It has developed the “Hong Kong: Blueprint for Sustainable Use of Resources 2013-2022” with strategy, targets, policies and action plans for waste management for the coming 10 years. This includes things like quantity-based waste charging, improving recycling infrastructure etc. All these actions are aimed to encourage HKers to be more mindful in their consumption choices and reconsider their habits in day to day life so to solve the waste crisis currently plaguing our city.
Another criteria we have discussed is Air Quality.
The HK government has the Weather Observatory incorporate Air Quality Index as part of the daily news report, and have a grading system ranging from Low to High. HK is on average 'Moderate'. Some ways the HK government had sought to improve air quality is through promoting electric vehicle use through tax incentives and advertisement, replacement of commercial vehicles with cleaner alternatives and policies that limit certain types of emissions.
A third criterion we have is Education.
In my opinion, this is something the HK government has done quite well.
It has invested in extensive advertising campaigns such as "Big Waster" - convincing citizens to buy only as much as they can eat and not waste food. Its quirky appearance appeals to adults and children alike.
It also focuses on environmental education in primary and secondary schools with the Green Hong Kong Campaign, many activities in which Shatin College itself has participated in (like the one person one flower scheme)'
For "Sustainable Urban Mobility", HK already has an extensive public transport system that is relatively cheap, with over 90% of people using the system every day. The government has also been encouraging electrical vehicles and replacing diesel fuels with other types.
In Noise Quality - Noise is a huge problem in HK, with the proximity of buildings to roads and each other amplifying roadside traffic and construction work. Some ways the government manages it is through traffic management schemes to ban certain types of vehicles from using some streets at night to reduce traffic noise, or resurfacing local roads.
In Nature and Biodiversity - HK has many policies and plans such as the Biodiversity Strategy and Action Plan (BSAP) 2016-2021 or the Protection of Endangered Species of Animals and Plants. Additionally, more than 75% of Hong Kong is undeveloped land or protected green space. Charities such as WWF are also active in HK, who often run environmental campaigns in protecting wildlife and help out in educating the public.
Lastly, there is the criteria "Green Growth and Eco-innovation". The government has not shied away from this. For example, it has invested in the Hong Kong Science & Technology Parks Corporation, which helps develop green technology in areas such as "building energy efficiency, environmental solutions, alternative energy, waste disposal and recycling, electric vehicles, and green electronics for infrastructure projects and carbon audits". It has recently also allocated a $300 million Pilot Green Transport Fund to support green technologies testing for public transport and goods vehicles.
