The report examines the role of South-South and Triangular Cooperation (SSTC) in fostering sustainable urban development and climate resilience in the Global South. It highlights the importance of the New Urban Agenda and the 2030 Agenda, arguing that traditional North-South cooperation is insufficient. Through various case studies from Africa, Asia, and Latin America, the document demonstrates how cities share knowledge on green transportation, water management, and urban planning. Key examples include Shenzhen's carbon trading, India's water resilience efforts, and Mexico City's green bonds. The report concludes that while cities are critical to the 'climate battle,' they often face institutional and financial barriers that SSTC can help overcome through peer-to-peer learning and innovative financing.

The report confirms the renewal of the IAI Implementation Committee's term and provides updates on the operational status of the Montevideo office and the Science-Policy liaison office in Buenos Aires, as well as ongoing discussions regarding the Science Development Directorate in Brazil.

The report details the extension of the Ad Hoc Commission for the Implementation of the IAI Tripartite Governance and provides updates on the operational status of the IAI offices in Montevideo and Buenos Aires, as well as ongoing discussions regarding scientific development leadership in Brazil.

The transportation sector accounts for approximately 25% of global CO2 emissions and is the second largest source of greenhouse gas emissions in Chile. A joint project by IISD, CC&D, and CCAP is investigating the application of the Clean Development Mechanism (CDM) to Chilean transport, focusing on technology and demand-side solutions. The project utilizes three case studies: bicycle infrastructure, bus technology switching (e.g., diesel to hybrid electric) in Santiago, and location efficiency through transit-oriented development. The initiative aims to address CDM challenges such as project baselines, additionality, and the potential for sector-wide initiatives to attract funding and technology transfer.

The report assesses the application of the Clean Development Mechanism (CDM) to Chile's transportation sector through three case studies: bus technology switching, bicycle initiatives, and location efficiency. It finds that the current project-based CDM framework is poorly suited for transportation due to the fragmented nature of emissions sources and the complexity of quantifying demand-side reductions. The authors argue that for the CDM to be effective post-2012, it must shift toward policy-based or sectoral approaches that can accommodate system-wide changes in travel behavior and land use.

The report analyzes bus system improvements across 13 cities in Latin America and Asia, highlighting the benefits of bus rapid transit (BRT) such as high usage levels and low capital investment. It identifies recurring failures in planning and implementation, including rushed launches and lack of integration with other transport modes. The document concludes with strategic recommendations for the planning and decision-making phases of urban transport reform.
