Extinction Rebellion protesters roadblock - Air quality impact

When climate activists Extinction Rebellion organised a 4 day roadblock of Deansgate in Manchester, we decided to measure its effects on air pollution levels.


Levels of black carbon, a key air pollutant emitted from engines that burn fossil fuels, were measured during and after the roadblock and the results are shown in the graphs above.


Climate protesters set up camp on Deansgate, one of Manchester city centre's most polluted streets.
