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

This research paper, the first in a series by the World Resources Institute, analyzes 10 international case studies from Europe, Asia, and the United States to identify effective public communication and consultation strategies for Low Emission Zones (LEZ) and Congestion Charging (CC) schemes. The paper emphasizes that public communication must be integrated into the policy design process from the earliest feasibility stages to secure public acceptance and ensure sustainable implementation.

• The paper identifies two distinct types of consultation processes used in international LEZ and CC schemes: scientific/professional and consultative/political. Examples of the scientific/professional approach include Singapore and Germany, while New York and Milan utilized the consultative/political approach.
• Public communication in the development of LEZ and CC policies is typically woven into a two-stage policy development process. The 'internal' stage involves defining possible policies in detail for consultation with a small group of politicians and experts, while the 'external' stage involves refining a single policy with the general public and a broader range of stakeholders.
• The document provides several recommendations for designing public communication strategies, particularly for the first such schemes in China. Key recommendations include starting communication as early as the feasibility study, ensuring communication is integrated with the scheme design and data collection, and focusing policy objectives on mitigating congestion or improving air quality. Additionally, the paper suggests using negotiation and granting exemptions to manage opposing opinions.
• Public acceptance is critical for the success of LEZ and CC policies, as these schemes often disrupt the established habits of businesses, commercial operators, and commuters. Securing this acceptance requires a combination of political will, a deliverable operational strategy, scalable scheme design, and a clear statement of initial policy objectives.
