22 October 2015 – The World Health Organization (WHO) today spotlighted the need to reduce short-lived climate pollutants like black carbon, ozone, methane and carbon dioxide that contribute to climate change and lead to more than 7 million deaths linked to air pollution each year.
“Every day, these pollutants threaten the health of men, women and children,” said WHO Assistant Director-General Dr. Flavia Bustreo upon release of the report, Reducing global health risks through mitigation of short-lived climate pollutants.
“For the first time, this report recommends actions that countries, health and environment ministries, and cities can take right now to reduce emissions, protect health and avoid illness and premature deaths, which often take the greatest toll on the most vulnerable,” Dr. Bustreo said.
WHO said it rated more than 20 available and affordable measures to mitigate short-lived climate pollutants, including vehicle emissions standards, capturing landfill gas, switching from fossil fuels to renewables, reducing food waste and improving household cooking fuels, to see which have the greatest potential to improve health, reduce emission of these short-lived climate pollutants and prevent climate change.
The report highlights four key interventions to reduce climate pollutants to relieve the pressures on climate change and human health:
Reducing vehicle emissions by implementing higher emissions and efficiency standards could reduce black carbon and other co-pollutants from fossil fuels, improve air quality and reduce the disease burden attributable to outdoor air pollution;
Policies and investments that prioritize dedicated rapid transit such as buses and trains and foster safe pedestrian and cycle networks can promote multiple benefits, including: safer active travel and reduced health risks from air and noise pollution, physical inactivity, and road traffic injuries;
Providing cleaner and more efficient stove and fuel alternatives to the approximately 2.8 billion low-income households worldwide dependent on primarily wood, dung and other solid fuels for heating and cooking, could reduce air pollution-related diseases and reduce the health risks and time invested in fuel-gathering;
Encouraging high and middle-income populations to increase their consumption of nutritious plant-based foods could reduce heart disease and some cancers, and slow methane emissions associated with some animal-sourced foods.
Evidence from previous WHO studies on healthy transport already suggest that shifts to mass transport and the introduction of safe walking and cycling networks are relatively inexpensive when compared with the loss of life and costs of treating people for air-pollution related illnesses, traffic injuries and diseases related to physical inactivity.
“The release of today’s report is a significant step in WHO’s ongoing work to prevent diseases and deaths related to air pollution – and towards achieving the new global health goal,” the health agency said.
In May 2015, the World Health Assembly adopted a resolution to address the health impacts of air pollution, which stresses the need for strong cooperation between different sectors and integration of health concerns into national, regional and local air-pollution-related policies.
Today’s report was produced in collaboration of the Climate and Clean Air Coalition to Reduce Short-Lived Climate Pollutants, a voluntary global partnership of governments, intergovernmental organizations, businesses, scientific institutions and civil society.
It comes ahead of the launch of WHO’s first climate change and health country profiles, a number of which will be released in advance of the UN climate conference, known as COP21, which will be held in Paris at the end of the year.
