Transport CO₂ emissions continue to grow globally despite advances in low-carbon technology and goal setting by numerous governments. In this Perspective, we summarize available evidence for the effectiveness of climate policies and policy mixes for road transport relative to 2030 and 2050 mitigation goals implied by the Paris Agreement. Current policy mixes in most countries are not nearly stringent enough. We argue that most regions need a stronger, more integrated policy mix led by stringent regulations and complemented by pricing mechanisms as well as other efforts to reduce vehicle travel.

为公路运输中的CO 2深度减排制定强有力的综合政策组合

交通运输CO ₂排放量继续尽管许多国家政府在低碳技术和目标设定的进步在全球发展。在此观点中，我们总结了相对于《巴黎协定》所隐含的2030年和2050年减排目标的气候政策和公路运输政策组合的有效性的现有证据。大多数国家的现行政策组合还不够严格。我们认为，大多数地区都需要以严格的法规为主导，价格机制以及其他减少车辆出行的补充，以实现更强大，更综合的政策组合。
