20. Policy Recommendation
1. Provide Definition for Brownfield
• Clear official definition
• Including land structure, current situation and policy
• Develop public database on Brownfield land
2. Formulate territory-wide integrated policy on
brownfield land
• Land Pollution paid by the polluters
• Subsidise environmental rehabilitation
• Subsidise industrial transformation
• Build multi-storey car parks to replace open temporary car-parks
3. Establish “Brownfield Priority” development
policy principle

21. Policy Recommendation
4. Develop public database on brownfield land
• updated annually and clearly denotes the existing purpose,
usage efficiency, property ownership, compatibility with
adjacent land in terms of land use of each brownfield site
• enables the general public to take up an overseeing role
on the issue of brownfield land extension
