Modelling Bilbao’s new Low Emission Zone impact using Opus data
Bilbao 2022

The city council of Bilbao commissioned Opus to carry out a study to characterize the emissions of the fleet of vehicles in the metropolitan area of Bilbao to support the design of its Low Emission Zone.
Opus collected real-world vehicle emissions data in multiple sites of the city to characterize the real-world emissions of every vehicle group in Bilbao and model the impact of different potential circulating restrictions on different vehicle groups.
Measurements showed that very few vehicles were extremely polluting, emitting much more (up to 300 times more) than the rest of the fleet. Specifically, only 2.8% of circulating vehicles were responsible for up to 47% of all road transport emissions. This means that identifying and acting on these highly polluting vehicles would be the most efficient policy to improve air quality.
The results showed that vehicles without an environmental sticker (a Spanish regulation that defines the theoretical polluting potential of each vehicle) were those with the greatest impact on total emissions generated in the municipality, comparable to the impact of ‘High-Emitter’ vehicles.
