The city has seen a number of built environment innovations in recent years including “smog-eating” buildings which help to combat air pollution and the engineering of “earthquake-proof” skyscrapers to withstand the region's seismic activity. Its phenomenal growth since the 1980s has been accompanied by air pollution and transport infrastructure issues, but the city has moved to address theseĪnd now has a clear plan for sustainable development in place between the present day and 2030.Ībove: Mexico City is predicted to be the only city in the America's in the top 10 by 2030.
