The legislative bill outlined here focuses on amending the way transportation projects are assessed and approved in Minnesota. It mandates a stricter environmental impact assessment of transportation projects, specifically examining how they align with the state's goals for reducing greenhouse gas emissions and vehicle miles traveled. Projects must meet certain criteria regarding these environmental targets before they can be included in state or metropolitan transportation improvement programs.

If a project doesn't initially meet these requirements, the responsible entity must either modify the project by changing its scope or design, remove or add projects to a portfolio, or implement sufficient impact mitigation measures. If these adjustments still don't bring the project into compliance, the development of the project must be halted, and it cannot be included in the planned transportation programs. This bill aims to ensure that transportation projects contribute to Minnesota’s broader environmental goals, particularly regarding the reduction of greenhouse gases and vehicle travel to combat climate change.
