In December 2018, Madrid implemented Madrid Central, a low-emission zone, with the intention of curbing nitrogen dioxide concentrations, which exceeded EU limits. The policy brought a substantial reduction in nitrogen dioxide concentrations during the first seven months after implementation. However, this impact did not extend much to the areas surrounding the low-emission zone. Furthermore, compliance dropped and emissions increased starting in July 2019, when it became unclear whether the policy would continue to be enforced.
Key points
  • 1
       Nitrogen dioxide concentrations were reduced by 27% over the period between January and June 2019, following the implementation of the Madrid Central low-emission zone.
  • 2
       Nitrogen dioxide concentrations decreased very little in the areas adjacent to the low-emission zone.
  • 3
       From July 2019, the low-emission zone policy showed no impact when compared with a baseline scenario in which no policy was in place.
  • 4
       The end of the effectiveness of Madrid Central coincided with a sharp increase in traffic citations for policy violations.
  • 5
       Lack of credibility around the enforcement of the policy may explain why Madrid Central ceased to be effective.
