In Colombia, the transport sector is the fastest-growing source of greenhouse gas emissions and urban areas increasingly suffer from traffic congestion and road safety concerns. The Colombian Transit Oriented Development (TOD) NAMA aims to address these issues by demonstrating how integrating urban planning and transport development in a city can reduce traffic growth by 25–36%, while improving air quality and living conditions.

Through this NAMA, the Colombian government aims to promote a more holistic approach to transport planning, with better coordination of land-use and transport systems, and their integration with social housing policy. This integration between different government agendas aims to promote public and private investment that will be channelled into pilot projects across a range of locations and interventions. Thus the project aims to promote better-designed, walkable, transit-oriented neighbourhoods and contribute to reducing household transportation costs, improving access to jobs and services, and enhancing social inclusion in the area.

A key part of the design of this NAMA includes the vertical integration between national and subnational policies and it is estimated that if fully implemented, it has the potential to reduce annual greenhouse gas emissions by between 3.6 and 5.5 MtCO2e by 2040.
