Detailed explanation-1: -By installing renewable energy units like solar panels and solar heaters across the city in private and public buildings over five years, the city aims to slash carbon emissions by 2 million tons to improve air quality in Mexico City.
Detailed explanation-2: -Located in the crater of an extinct volcano, Mexico City is about 2, 240 metres above sea level. The lower atmospheric oxygen levels at this altitude cause incomplete fuel combustion in engines and higher emissions of carbon monoxide and other compounds. Intense sunlight turns these into higher than normal smog levels.
Detailed explanation-3: -Overall, Mexico was one of the first countries in the world to pass a specific law on climate change. The law set an obligatory target of reducing national greenhouse gas emissions by 30% by 2020. The country also has a National Climate Change Strategy, which is intended to guide policymaking over the next 40 years.
Detailed explanation-4: -Among the worst hazards of that air pollution for its 21 million inhabitants is PM 2.5, inhalable fine particulate matter. People exposed to PM 2.5 can suffer from coughing, shortness of breath, bronchitis, respiratory infections and heart problems.
