加州的排放标准会影响其他州的车队吗？

继联邦政府近期撤销加州排放豁免后，本报告探讨了加州的车辆排放标准如何透过被17个州和华盛顿特区采用，继续影响全国范围内的车队行为。报告概述了影响加州的法律和监管框架，包括 "清洁空气法" 的豁免条款以及加州空气资源委员会 (CARB) 的角色。报告强调了加州 "先进清洁汽车和卡车" 计画在加速零排放汽车 (ZEV) 普及方面的有效性，科罗拉多州是成功复製该政策的重要案例。诸如 Diamond Alternative Energy v. EPA 等法律课题凸显了州级权力和排放监管未来发展之间日益加剧的紧张关係。 Guidehouse Research 建议监管机构采取策略性行动以维护豁免权，各州应制定相应的法律辩护方案，并建议汽车製造商根据 CARB 的市场需求调整其产品计划，以降低风险并保持竞争力。

目录

• 加州清洁空气法案 (CAA) 豁免以及加州空气资源委员会 (CARB) 的演变和全国影响
• 法律、政治和执法动态如何影响加州式排放法规的采用和有效性
• 加州排放政策如何影响汽车製造商策略并推动市场变革

In response to recent federal actions rescinding California's emissions waivers, this report explores how California's vehicle emissions standards continue to shape national fleet behavior through adoption by 17 states and Washington, DC. It outlines the legal and regulatory framework that enables California's influence, including the Clean Air Act's waiver system and the role of the California Air Resources Board (CARB). The report highlights the effectiveness of California's Advanced Clean Cars and Trucks programs in accelerating zero-emission vehicle (ZEV) adoption, with Colorado serving as a key example of successful policy replication. Legal challenges, such as Diamond Alternative Energy v. EPA, underscore the growing tension over state-level authority and the future of emissions regulation. Guidehouse Research recommends that regulators act strategically to preserve waiver authority, that states coordinate legal defenses, and that OEMs align product planning with CARB-aligned markets to mitigate risk and maintain competitiveness.
