Terminal Binjai transport hub transformed by community-led design
The project transformed Terminal Binjai from an inefficient, inaccessible transit hub into a safe, inclusive node for green mobility through a participatory process. Key interventions included a design competition involving university students and residents, 'transect walks' to identify pain points, and the implementation of low-cost 'tactical urbanism' upgrades. These changes resulted in improved lighting, accessible pathways, and weather-protected shelters, complemented by the addition of 30 new buses to the bus rapid transit (BRT) system. The project's methodology has been codified into a Digital Mapping Toolkit to support equitable urban transport planning in other cities globally.

Dar es Salaam CITY PROFILING REPORT 2025
Dar es Salaam is one of Africa's fastest-growing cities and Tanzania's economic hub, though it faces significant challenges in infrastructure and governance. While the city's GDP is growing and it leads the country in startups and telecommunications, it is characterized by high levels of informality, with 70% of the population living in informal settlements. Public services such as water, sanitation, and waste management are underperforming, and the city is highly vulnerable to flooding and urban heat. Governance is heavily centralized, with local authorities relying on the national government for approximately 75% to 90% of their revenue, severely limiting their fiscal autonomy and ability to address local needs.

A Sustainable Asset Valuation of the Sustainable Transport Strategy in Bogota, Colombia
The report applies the SAVi methodology to analyze two scenarios for Bogota's transport infrastructure: a current scenario (20102022) focusing on BRT and NMT, and a future scenario (20102058) including the MRT system. The analysis finds that while conventional benefit-cost ratios (BCR) are low (0.3 to 0.6), the sustainable BCR (S-BCR), which incorporates externalities like health, retail revenues, and CO2 emissions, is significantly higher (3.8 to 6.1). The most substantial added benefits are identified as retail revenues and property value increases, while the only negative value is the time lost due to increased walking and cycling. The report concludes that the strategy is an attractive investment that improves quality of life and supports climate targets.

Financing Transport Projects
The briefing argues that conventional neoclassical financial analysis fails to account for long-term non-financial risks and externalities, often leading to underinvestment in sustainable transport. It proposes an 'integrated financial analysis' where positive externalities—such as health benefits and time savings—are monetized and converted into revenue streams. Using a case study of a Bus Rapid Transit (BRT) system in Bandung, Indonesia, the paper demonstrates that while the project is financially unviable based on ticket sales alone, it becomes viable if a small fraction (12% to 19%) of its societal externalities are internalized. The author recommends lowering social discount rates to better incentivize long-term sustainable investments.

A Sustainable Asset Valuation of a Net-Zero Transport Strategy in Indonesia
The report evaluates three primary net-zero transport scenarios for Indonesia: investment in public transport (Scenario 1), 100% private vehicle electrification powered by renewable energy (Scenario 2), and a mixed approach (Scenario 3). Using the SAVi methodology, the analysis finds that Scenario 3 delivers the highest cumulative discounted net benefit of IDR 6,926.03 trillion (USD 450.1 billion) by 2050. While Scenario 2 offers the most attractive benefit-cost ratio (BCR) of 1.97 due to lower infrastructure costs, Scenario 3 provides the greatest overall societal value by combining 'avoid, shift, and improve' strategies. The report emphasizes that achieving net-zero in transport is inextricably linked to the decarbonization of the electricity supply, as sensitivity analyses show that the current energy mix significantly reduces net benefits.

The Road to Sustainable Transport
The document argues that transport is a critical driver of development but a major source of emissions, accounting for 23% of energy-related CO2. It defines sustainable transport as safe, affordable, and efficient mobility that minimizes environmental impacts. The report details the evolution of international policy from the 1972 Stockholm Conference to the Sustainable Development Goals, and provides examples of successful interventions, such as Jakarta's BRT system and various cities' shifts toward active mobility (cycling and walking). It specifically notes the COVID-19 pandemic as a catalyst for structural changes in urban transit, though it warns that 30 major economies continue to provide significant subsidies to fossil fuels over clean energy.

Mainstreaming gender in urban public transport
The report examines gender inequality in the urban public transport sectors of Nairobi, Kampala, and Dar es Salaam, finding that transport systems are generally designed for young, fit men and fail to address the specific mobility needs, safety concerns, and employment barriers faced by women. While national constitutions and gender policies in Uganda, Tanzania, and Kenya provide a foundation for equality, specific transport policies often generalize users and lack explicit gender-responsive measures. The study highlights significant risks of sexual harassment and assault, the underrepresentation of women as drivers and operators due to social stigma and structural barriers, and a lack of gender-disaggregated data to inform policy. It suggests that the introduction of Bus Rapid Transit (BRT) systems and the rise of online taxi-hailing services present opportunities to integrate gender-sensitive infrastructure and flexible employment for women.
