City-Level Action Is The Right Way To Tackle Emissions

Countries seeking to meet Paris Agreement targets on CO2 emissions must get a grip on the amount of pollution produced at city level, according to researchers at the University of East Anglia (UEA). In a new study, published in Science Advances, the researchers set out a framework for gathering and analysing local information about how cities contribute to pollution levels, and show how these insights could be used to target climate mitigation initiatives most effectively. Using China as a model, the team has compared emissions data from 180 cities across the country, looking at the industrial make-up of each city, its socioeconomic profile, and the types of energy produced and consumed. The researchers used the data to classify cities according to different levels of industrial development and worked out the potential for emission reduction amongst the different groups.
