PATH v3.0 Scenario Analyses beyond Year 2030

Hong Kong Emission and Air Quality Scenario Projections beyond 2030

Introduction
To provide a reference on the overall projected air quality in Hong Kong for the air quality impact assessment (AQIA) beyond 2030, the EPD has reviewed the latest emission & air quality trends, and air emission control strategies to derive scenario projections for the following assessment year(s).

1. Year 2035
2. Year 2040

It should be noted that the assumptions for the scenario projection(s), as provided below, are derived based on the expected outcomes at the specified time. It is not a policy commitment by the Government, and interested parties should evaluate the appropriateness of the assumptions with respect to each case's specific conditions & requirements at the time of AQIA, and make appropriate adjustments/refinements as necessary.
