Evaluation on Air Pollutants Reduction Effects of Beijing Low Emission Zone and Congestion Charging Policies

Faced with severe congestion and air quality issues, the Beijing Municipal Government has issued a series of transport demand management (TDM) measures and energy conservation and emissions-reduction policies. However, one of the main challenges for the government is to quantify the emissions-reduction effects of different policy schemes and compare the effectiveness of those schemes. Based on current vehicle emissions in Beijing and prevailing international vehicle emission models, Beijing Transport Institute and World Resources Institute made this report in corporation. In order to guide the government to formulate reasonable policy measures and reduce pollutants, this research developed an evaluation methodology that can be applied to Beijing transport policies, especially LEZ/CC policies.

Study on International Practices for Low Emission Zone and Congestion Charging

The traffic congestion and its high socioeconomic cost, brought by China’s fast urbanization, has forced the demand for congestion mitigation and emission reduction in the transport sector onto the government’s agenda. Several Chinese cities like Beijing, Shanghai, Hangzhou and Suzhou are considering to mitigate these growing air pollution and traffic congestion issues through Low Emission Zone (LEZ) and Congestion Charging (CC) policies. Based on the policy demands from Beijing Municipal Commission of Transport (BMCT), World Resources Institute (WRI), partnering with Beijing Transportation Institute (BTI), has conducted a comprehensive and thorough research on the successful experience of London, Singapore and Stockholm that have initiated LEZ/CC, with analysis focusing on preparation stage, scheme design, technology, public communication, implementation and management, and policy effects. This working paper discusses practices that can be applied to China, aiming to solve problems and challenges in the effort of congestion mitigation and emission reduction.

International Case Studies on Public Communication and Consultation Strategies for Low Emission Zones and Congestion Charging Schemes

The working paper will be part of the “Low Emission Zone/Congestion Charge (LEZ/CC) Public Communication Strategies” series of papers to offer a comprehensive package of public communication strategies to safeguard successful implementation. It is the first paper in the series, and studies 10 cases from Europe, Asia, and the United States to highlight the variety of social, political, and environmental contexts within which CC and LEZ schemes were planned and implemented. From the examples studied, two types of consultation process were identified; scientific/professional and consultative/political. All of the international case studies highlight how public communication is woven into the policy development process, which itself may be split into two stages: ‘internal’ and ‘external’ for a LEZ or CC within an integrated transportation package.
