Transport and Covid-19: responses and resources

Strategies for Mitigating Air Pollution Workshop

ITF Meeting ITF Meeting

Mexico City experienced ozone alerts on a total of 16 days in the spring of 2016 and new smog episodes can be expected as early as February, Mayor Miguel Mancera told a workshop on counter-measures to air pollution convened by ITF and the Development Bank of Latin America in Mexico City on 18-19 January. Major improvements have been made, but ozone and particulate matter levels regularly exceed health limits. Mexico City is addressing the issue through integrated strategies for more sustainable mobility and improved emergency response measures. The workshop, attended by Mayor Mancero and Environment Minister Tanya Muller (pictured) shared experiences from London, Paris, Milan, Shanghai, Beijing, California and Japan and examined the drivers of excess emissions in real-world driving conditions with some of the world’s leading experts.

Recommendations included basing incentives for cleaner vehicles on the very latest emissions standards, avoiding any transition through the much less effective earlier standards: Euro VI / US EPA 2010 for trucks and buses to cut NOx emissions substantially; US EPA 2010 Tier 3 for cars to deal with evaporation of gasoline in Mexico’s hot, high altitude conditions; Euro 6 to limit emissions of nano-particles from gasoline as well as diesel cars.

Nano-particles are the most toxic and harmful of all pollutants but are too small to weight only the latest heavy duty vehicle standards and Euro 6 light duty vehicle standards impose a restriction on the number of particles emitted, regulating ultra-fine particles for the first time. Electric vehicles are also part of the strategy for cutting emissions as free of tail-pipe emissions.

Stress was also put on the effectiveness of speed limits in delivering immediate reductions in emissions by calming traffic, increasing flow on congested highways and reducing stop-go traffic at the same time as dissuading hard acceleration and excess speed. This was echoed by the Mayor in his press conference and articles reporting the event in the national papers. The city’s efforts to improve conditions for cycling and walking and invest in improved public transport, with better planning and coordination of bus services across the metropolitan area were also underlined as central to containing pollution.
