Note
This summary dashboard is based on the London Atmospheric Emissions Inventory 2022. The charts show emissions from each air pollution source stacked on top of one another, with the total stack height equalling total emissions from all sources across the borough. The numbers in the table are those used to plot the graph and represent, for each year, the amount of pollutant emitted into the atmosphere (in tonnes/year).
- Industrial Processes: includes emissions from Part A1, A2/B processes, and Non-Road Mobile Machinery (NRMM) exhaust on industrial sites.
- Construction: includes emissions from construction dust (PM) and NRMM exhaust on construction sites.
