1. C40 Cities Climate Leadership Group Inc.
C40 is a network of nearly 100 mayors of the world’s leading cities working to deliver the urgent action
needed right now to confront the climate crisis and create a future where everyone, everywhere, can thrive.
Mayors of C40 cities are committed to using a science-based and people-focused approach to limit global
heating in line with the Paris Agreement and build healthy, equitable and resilient communities. We work
alongside a broad coalition of representatives from labour, business, the youth climate movement and civil
society to support mayors to halve emissions by 2030 and help phase out fossil use while increasing urban
climate resilience and equity.

About the social housing retrofit project
Social housing retrofitting increases energy efficiency, reduces greenhouse gas emissions, and elevates
living conditions for communities most in need by reducing energy bills, improving health, and providing
and increasing liveability and therefore a sense of belonging.
Buildings account for about 40% of global greenhouse gas emissions due to the materials and fossil fuels
used to construct, heat, cool, and power them. Decarbonising buildings is a critical global challenge, as
many of them are energy inefficient, resulting in unnecessarily high energy costs, high emissions of carbon
and other pollutants, and substandard living conditions. In the Latin America and Caribbean (LAC) region,
approximately 25.5% of the population is currently classified as low-income. Within this group, energy
costs tend to be high. According to ECLAC and the International Energy Agency (IEA), while an average
household spends between 7% and 9% of their total income on energy, low-income households spend
more than 12%, reaching up to 24% in extreme cases.
Understanding “vulnerable populations” as groups with limited access to income, urban infrastructure, and
adequate housing, cities have the potential to protect and improve the resilience of their most at risk
residents by supporting the retrofit of social housing stock with modern energy-saving improvements.
These features can include technologies such as LED lights, solar photovoltaic panels, heat pumps, or
induction stoves. By implementing these retrofits, cities can conserve energy and reduce emissions while
improving living conditions for their residents.
C40 Cities is working with Mexico City to advance its social housing retrofitting goals through the "Casa
Ecológica: Transformando la Ciudad" project, an initiative by the Ministry of the Environment (SEDEMA)
that aims to lower emissions and improve the quality of life for low-income residents in climate-vulnerable
areas.
City background
Mexico City’s greenhouse gas inventory has estimated that the residential sector is the city’s
second-largest energy consuming sector, and the primary consumer of Liquified Petroleum Gas (LPG)
across all sectors, accounting for 64% of the total LPG consumption in the City. Furthermore, it has been
established that 4 out of 10 households suffer from LPG leaks. The combustion processes and leaks from
LPG supply and distribution generate more than 42,000 annual tons of Volatile Organic Compounds
(VOCs), additionally representing an economic loss of 2.6 million MXN daily due to leaks. Because of this,
according to the Local Climate Action Strategy (ELACC) 2021-2050, the decarbonization of housing is
considered a fundamental priority for achieving climate neutrality, with an emissions reduction potential of
up to 60.7% through transition to renewable sources of energy.
About Casa Ecológica
Currently, the Ministry of the Environment (SEDEMA) is implementing the "Casa Ecológica: Transformando
la Ciudad" project. The project includes the installation of 3 eco-technologies (domestic solar water
heaters, rainwater harvesting systems, and urban gardens) in 7,000 climate vulnerable homes in 5
neighbourhoods in the Coyoacán and Tlalpan districts. For 2026, the program has an overall budget of 200
million MXN for th
