Today we review research on the top sources of air pollution and greenhouse gas emissions in the country considered by many to be the most polluted in the world.  Results indicate that this is not emissions of Black Carbon from cooking food in homes and restaurants- so-called biomass sources-  but from the burning of coal in cities and from vehicle emissions in traffic. This will allow authorities to plan for efficient mitigation of climate change because Black Carbon has a shorter lifetime in the atmosphere (days, weeks) than other greenhouse gases, such as CO2 (decades, centuries).
