Since then, CPSU has collaborated with national and local governments, regional entities, international cooperation agencies, corporate and private sector, non-profits, communities and activists. We have supported these actors in developing policies, guidelines, plans, tools, and strategies in areas such as climate action, sustainable transport, gender inclusion, waste management, reducing inequalities, improving public spaces and community integration, sparking urban innovation, and regenerating nature in cities. Because of our work, CPSU is currently recognized as one of the leading organizations in Costa Rica in terms of urban sustainability and sustainable, low carbon transport, and our team members are constantly involved and consulted in both local and international discussions regarding these topics.

An example of our work regarding informal or popular transport was the Informal Transport Encyclopedia for Central America. This publication had the support of Agile City Partners, the Global Partnership for Informal Transport, University College of London and was financed through the UK Embassy. To collect information on informal transport, a datathon was held, where participants were able to compile information on the types of vehicles used, payment methods, routes, the names associated with these services, among other relevant information. All the data allowed us to create a first picture of how informal or popular transport operates in the region and how it contributes to the mobility and economic contexts of our cities in the Global South.
