Fallstudien der Pacific Coast Collaborative Embodied Carbon Policy

This document highlights ten case studies of policies driving lower carbon construction across the Pacific Coast. Each case explores the development process, challenges faced, and lessons learned through the policy process. Information was gathered from interviews with PCC members who were involved in the policy, publicly available policy reports, as well as interviews from the implementing agency of the policy.


The PCC Low Carbon Construction Task Force, launched at COP26 in November 2021, is a regional initiative between California, Oregon, Washington, British Columbia, San Francisco, Seattle, Los Angeles, Oakland, Portland, and Vancouver to advance low-carbon materials and methods in building and construction projects. The Task Force aims to create a shared regional strategy with the goal of accelerating innovation, investment, and market development for low carbon materials by leveraging the scale of the Pacific Coast regional economy. The CLF began supporting the taskforce as a technical resource in 2022.

Diese Fallstudien demonstrieren die politische Führungsrolle der Region in Bezug auf kohlenstoffarmes Bauen und bieten Einblicke, um andere Gerichtsbarkeiten zu informieren, die Gesetze und andere Richtlinien innerhalb der Pazifikküstenregion und darüber hinaus verfolgen.
