Colombia’s National Roadmap for Net Zero Carbon Buildings
Decarbonizing the buildings sector is essential to cutting global greenhouse gas emissions. In Colombia, buildings account for 7% of national emissions – smaller than in many countries in part because of the country’s large agriculture, forestry and land use emissions – but it’s taken a big step toward decarbonizing the sector with a new roadmap that bridges national targets with local action. Colombia’s National Roadmap for Net Zero Carbon Buildings, launched in June 2022 by the Ministry of Environment and Sustainable Development, aims to achieve net zero in all new buildings by 2030 and all buildings by 2050. Developed in partnership with WRI’s Zero Carbon Building Accelerator, the roadmap provides a framework for how the country can decarbonize the built environment by setting out clear goals, defining actions and identifying the actors responsible for implementation. To achieve sectoral transformation, short-, medium- and long-term actions have been identified across the value chain of the buildings and construction sector – including urban planning, materials, transportation and distribution, design, labeling, certification, water and energy use, and waste management. The roadmap assesses the current status of the buildings sector and evaluates potential social and environmental impacts of net zero buildings nationally. To reach the ambitious goal of decarbonizing the built environment, the roadmap breaks down 67 goals and 175 transformative actions across six areas: Corporate Practices, Materials, Urban Planning, New Buildings, Existing Buildings and Informal Settlements. Colombia is distinct in that it includes the informal construction sector alongside the formal in its net zero planning. Nationally, unlicensed buildings account for 19-29% of the building stock and as high as 55-70% in some cities. This unlicensed or informal sector presents a significant challenge to decarbonizing the built environment. “Formalizing” it could reduce construction and demolition waste, improve building materials, and improve the quality of life and health of low-income families. But doing so affordably and justly, without displacing residents, has been difficult for many cities. The roadmap includes recommendations for ensuring that improving existing homes and buildings takes a participatory, inclusive approach with communities. It also highlights the importance of financial education and programs for communities to make access to formal housing more viable – for example, alternative leasing and mortgage schemes for those without traditional access to financing. The country has developed regulations and incentives for energy efficiency, clean energy and grid decarbonization. However, there are still regulatory short-falls and barriers, and access to highly efficient building technologies is still lacking.
