'Barcelona's air quality improved significantly in 2023, reaching the lowest
levels of nitrogen dioxide since records began 25 years ago.
The reduction in levels of nitrogen dioxide, a traffic-related air pollutant,
is largely due to the implementation of Low Emission Zones (known by its
acronym in Catalan, ZBE.)
Since the introduction of the ZBE in 2020, last year was the first year that
there were more cars with the ECO label in the city than those with the B
(yellow) label, meaning cars polluting less.
Deputy mayor Laia Bonet said the improvement was due to "policies and positive
decisions" and pointed to the ZBEs as "key".
Other measures that have contributed to this achievement include decarbonizing
public transportation, pedestrianizing streets, promoting bicycle use, and
reducing car speeds, she said.
Pollution levels in Barcelona are now close to those seen in 2020 and 2021,
during the height of the Covid-19 pandemic, but now, the city is back to full
activity.
In 2023, levels of nitrogen dioxide and particulate matter PM10 and PM2.5 were
all below the legal limits set by the European Union.
However, pollution levels still exceed the limits set by the World Health
Organization (WHO) and the European targets for 2030.'
