Air Quality And Greenhouse Gas Impacts Of Transportation

Environmental Guide for Assessing and Mitigating the Air Quality Impacts and Greenhouse Gas Emissions of Provincial Transportation Projects. To provide a more defensible evaluation of the air quality/ greenhouse gas impacts of highway projects, used in environmental assessments, the Ministry of Transportation has developed a standardized approach for assessing and mitigating the air quality impacts and greenhouse gas emissions of provincial transportation projects ("the Guide").

The Guide uses a critical path methodology, focussed on whether the NOx or PM2.5 or greenhouse gas emissions of the proposed project would > 0.1% of provincial total, and on whether there are credible Transportation Planning Alternatives to the project with differences of Route Lengths > 10% or 1km.
