Reducing air pollution concentration by 50%: A case study from Mexico – webinar and related resources

3pm, April 05th, 2016

This bundle of resources, from the Transport Working Group of LEDS GP, presents the webinar recording, slideshow and related resources from our webinar on how Mexico has diminished air pollution concentration by more than 50%.

During the 1980’s, Mexico was known worldwide for its air quality problems. Mexico City, in that time, was considered the most polluted city in the world. Nowadays, despite having four times more vehicles, authorities have reduced air pollution concentration by more than 50% through a public policy integrated approach,

In this webinar, Jorge Macias, discusses the history, public policies and challenges that Mexico has faced in terms of its private vehicle fleet management and how Mexico’s cultural and socioeconomical proximity makes its experience particularly interesting given the possibility of replicability. Jorge Macias is currently the General Deputy Director for the Environmental Commission for the Central Region of Mexico where he focuses on coordinating, harmonizing and implementing public policies in the six entities that form the commission.

  • Air pollution in Mexico City documentary: The air pollution concentration in Mexico City is a serious problem that is shown in this short video.
  • Mexico City’s air pollution: The pollution improved after a switch to unleaded gasoline and a public transportation expansion, but government officials say there is still more to be done.
  • Snapshot | Martita: In the suburbs in the outskirts of Mexico City, residents like Martita are under-served by mass transit. It can take anywhere from two and a half, to three hours to commute to and from work. Unreliable service and daily breakdowns are just part of Martita’s daily commute.
  • Mexico City’s pollution: Towards a Better Future: Short film about Mexico City’s pollution.
  • Mexico moves to fight smog: For over two decades, Mexico City has battled to combat air pollution and smog with a slew of measures. And they’re paying off as old exhaust-belching vehicles are phased out and the megacity becomes greener.
  • Harvard experts tackle housing, pollution, and traffic in Mexico: In 1992, the United Nations called Mexico City’s air quality the planet’s worst, so bad that flying birds, overwhelmed, would fall dead from the sky. By 1998, the U.N. called Mexico City the world’s most dangerous city for children’s health.
  • Inside the Americas – Mexico City traffic: With five million motor vehicles in the Mexico City metropolitan area, the air pollution concentration is among the worst in the world, to the extent of being considered a public health and environmental threat.


  • Global Fuel Economy Initiative (GEFI) auto fuel efficiency toolkit: This tool is designed to provide policymakers and interested individuals and groups with overviews of policy tools and approaches to improving fleet-wide automobile fuel efficiency and promote lower CO2 and non-CO2 emissions from cars, along with case studies that depict these approaches from developed and developing countries.
  • Global Fuel Economy Initiative (GFEI): The Global Fuel Economy Initiative has launched the 50by50 challenge to facilitate large reductions of greenhouse gas emissions and oil use through improvements in automotive fuel economy. The website provides access to working papers, a map showing countries with fuel economy standards, and other related information.
  • LEDS GP Transport Toolkit: The Low Emission Transport Toolkit supports development planners, technical experts, and decision makers at national and local levels to plan and implement low emission transportation systems that support economic growth. This toolkit helps users navigate a variety of resources to identify the most effective tools to build and implement low emission development strategies (LEDS) for the transport sector.
  • provides comprehensive information on energy and environmental regulations in the transportation sector worldwide, with a focus on emissions and fuels.
  • Partnership for Clean Fuels and Vehicles regulatory toolkit: This toolkit will support developing and transitional countries to introduce requirements for 50 ppm and below sulfur fuels; produce or import lower emitting and more efficient vehicle technologies; establish vehicle emissions control roadmaps; and ultimately improve air quality and human health in these countries.Infographics
  • Air pollution in Mexico City: Report with multiple graphics on air quality in Mexico City.
  • Sources of air pollution in Mexico City: Sources of volatile organic compounds (VOCs), nitrogen oxides (NOx) and Sulphur dioxide (SO2) in Mexico City.
