Source International Council on Clean Transportation 如果要让交通运输为全球变暖控制 1.5 C以下做出贡献，它将需要在 2020年的水平上减少 78的二氧化碳排放，在 2050年的预计基线水平上减少 88。资料来源国际清洁运输理事会 4 The International Council on Clean Transportation estimates that worldwide in 2020, 43 of CO2 emissions came from light duty vehicles 34 from heavy duty vehicles 34来自重型车辆和公共汽车， 11来自海运， 10来自航空， 2来自铁路。 If we are going address the causes of climate change, we must find ways to decarbonize the entire transport sector. 如果我们要解决气候变化，我们必须找到让整个交通部门脱碳的方法。 Our strategies will need to focus as much on freight and aviation as on surface passenger travel. 我们的战略既要关注地面客运，也要关注货运和航空。 This is a global issue that will require a global approach to addressing the problem. 这是一个全球性问题，需要采取全球性办法来解决这个问题。 5 The Climate Change Challenge 气候变化 According to ICCT, 90 of the growth in CO2 emissions between now and 2050 is projected to occur in China, the Asia Pacific region, India, and Africa, driven almost entirely by increased travel demand. 根据 ICCT的预测，从现在到 2050年， 90的二氧化碳排放增长将发生在中国、亚太地区、印度和非洲，几乎完全由出行需求的增长驱动。 The challenge is to reduce emissions without impacting economic growth in these parts of the world. 我们面临的挑战是在不影响这些地区经济增长的情况下减少排放 At the same time, North America and Europe will need to reduce emissions from existing levels by significant amounts. 与此同时，北美和欧洲将需要在现有水平上大幅减少排放。 This will be a daunting challenge that will require an international commitment by policy makers and the public 这将是一项艰巨的挑战，需要决策者和公众的国际承诺 6 The Climate Change Challenge 气候变化 Strategies to Reduce GHG Emissions 减少温室气体排放的策略 Conversion of the vehicular fleet to zero emission vehicles 将车辆转为零排放车辆 Emission reductions in remaining internal combustion ICE vehicles 减少内燃机 ICE车辆的排放 Policies to reduce travel demand 减少出行需求的政策 Electricity generation from renewable sources 可再生能源发电 Taxing and pricing policies 税收和价格政策 Use of alternative modes of transportation 使用其他运输方式 Telecommunications as a substitute for travel 电信作为旅行的替代品 Although all of the above will need to be pursued, the vast majority of reductions will need to come from vehicular emissions reductions, i.e. decarbonization of the vehicle fleet. 虽然以上所有的目标都需要实现，但绝大多数的减排将需要来自于车辆减排，即车辆的脱碳。 7 Decarbonization Challenges 减碳挑战 Conversion from manufacturing internal combustion engines ICE vehicles to electric vehicles EVs 车辆向电动化转变 Changing consumer demand to want to buy electric vehicles 改变消费者需求 – Overcoming range anxiety 克服续航焦虑 – Initial costs are still higher for Evs 居高不下的初始成本 Battery technology challenges 电池技术难题 – Increasing battery capacity without increasing weight 增大容量时如何维持重量 – Increasing the range of electric vehicle batteries 增加电动汽车电池的使用范围 – Supply of materials for batteries especially rare earth materials 电池材料供应（特别是稀土材料） – Recycling of used batteries 废旧电池的回收 8 Vehicle charging infrastructure 充电基础设施 – Providing charging stations in locations where market demand is low 充电站点的选择 – Fast charging infrastructure 快速充电 Capacity of electric grid 电网容量 Conversion of electricity generation to renewable sources 发电向可再生能源靠拢 Economic impacts 经济影响 – Impacts to supply chain for ICE vehicles 影响传统汽车供应 – Impacts to repair and maintenance service and parts providers 影响维修、维护、零部件供应 – Impacts to service stations 影响服务站 9 Decarbonization Challenges减碳挑战 Fleet turnover challenges 车辆周转率 – ICE vehicles will be the majority for many years to come 未来传统能源汽车仍将占据主流 – How can we reduce emissions of the existing fleet 如今的车辆构成如何减排 Goods movement 货物运输 – Battery technology is insufficient to generate power needed for long distances; major advances needed in clean propulsion power 电池不足以支持长途运输；清洁能源动力需要重大进展 – Future of hydrogen as principal energy source to replace diesel 氢能作为主要能源的未来 Aviation 航空 – Sustainable aviation fuel 可持续燃料 – Modal diversion of short trips 短途旅行有更多选择 10 Decarbonization Challenges 减碳挑战 Collaboration Is Critical 合作的重要性 Decarbonization is a global challenge that will require all nations to be working together to address. 脱碳是一项全球性挑战，需要所有国家共同努力解决。 There are many issues and challenges that require us to collaborate. 许多问题和挑战需要合作。 We can and must learn from each other about research and deployment results, lessons learned, and future challenges. 我们能够，而且必须在研究和部署成果、经验教训和未来挑战方面相互学习。 This applies to both technical and policy issues. 技术问题和政策议题均是如此。 We have a daunting challenge that we must solve together, and we need to be collaborating on the full range of issues associated with decarbonization 要共同解决这个艰巨的挑战，我们需要在与脱碳相关的所有问题上进行合作 11 Transportation Research Board TRB website www.trb.org Sign up for the TRB weekly e-newsletter 订阅每周时讯 Become involved as a Friend of a TRB Committee 加入委员会 www.MyTRB.org TRB TRID database 数据库 www.trid.trb.org TRB Annual Meeting, Washington, DC, Jan. 8-12, 2023 2023年 TRB年会 1月 8日至 12日，美国华盛顿 12 Neil J.
