The Hong Kong Government's "Public Engagement Document", on Electronic Road Pricing (ERP) and the upcoming pilot project in central, has been released. We encourage all road users in Hong Kong to read the proposal, and get involved with the consultative process.
While the primary purpose of ERP is to reduce congestion, it also has a significant impact on roadside pollution and air quality. Most countries around the world introducing such ERP systems have recognised that fact and incorporate measures to make sure that the polluters pay (by either charging high polluters more, or providing concession for environmentally friendly vehicles). We hope that Hong Kong will follow this approach, as it has had excellent results overseas.
