Air quality and transport in Bogotá

Diesel vehicles and industry affect air quality, while bus rapid transit and cycling policy offer internationally studied responses.

Bogotá · Colombia

01 · The problem

What is happening

Bogotá's air quality is affected by diesel buses and trucks, industry and resuspended dust, with pollution often worse in the southwest of the city. Bogotá is known for TransMilenio, a large bus rapid transit system opened in 2000, its Ciclovía — weekly car-free streets — and an extensive cycle network. The city has been adding electric buses to its fleet, which has become one of the largest electric bus fleets outside China.

02 · Causes

Why it is happening

  1. 01

    Diesel vehicles

    Older buses and freight trucks emit fine particulate matter.

  2. 02

    Industrial emissions

    Industry in the southwest contributes to local pollution.

  3. 03

    Road dust

    Unpaved and poorly maintained roads resuspend dust.

03 · Impacts

Who and what it affects

  1. 01

    Health effects

    Particulate exposure is associated with respiratory and cardiovascular disease.

  2. 02

    Unequal exposure

    Pollution is often concentrated in lower-income districts.

04 · Solutions

Documented approaches

  1. Electric bus fleet

    Replacing diesel buses with electric buses.

    Expected effectReduces tailpipe emissions along bus corridors.

  2. Cycling infrastructure and Ciclovía

    Protected cycle lanes and weekly car-free streets.

    Expected effectSupports low-emission travel and active lifestyles.

  3. Monitoring and alerts

    The city's air quality monitoring network with public alerts.

    Expected effectInforms action during pollution episodes.
