The Federal Mortgage Society (Sociedad Hipotecaria Federal, SHF) provides bridge loans with a preferential rate for developers to construct houses using eco-technology. This project is expected to help cut over 1 million tonnes of GHG emissions over 40 years, the estimated lifecycle of these houses. The air quality plan seeks to minimise emissions, while transport planning seeks to increase mobility. Transport activities are not funded or approved unless they conform to the purpose of the air quality plan.
