The World Health Organisation (WHO), has expressed alarm at the growing cases of lung cancer, resulting from air pollution.
Added to this, are cardiovascular diseases and respiratory infections.
It said exposure to air pollution was causing seven million deaths, every year, and an estimated US$5.11 trillion in welfare losses, globally.
Dr. Maria Neira, the WHO’s Director of Public Health, Environment and Social Determinants of Health, announced this at the launch of s Special Report by the UN’s specialized agency, at the ongoing 24th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP24) in the Polish city of Katowice.
She said the true cost of climate change was being felt in the hospitals and in the lungs of the people of the world from the continuous greenhouse gas emissions.
“In the 15 countries that emit the most greenhouse emissions, the health impacts of air pollution are estimated to cost more than four per cent of their Gross Domestic Products (GDP).”
Actions to meet the Paris Climate Change Agreement would cost around one per cent of global GDP.
She said the health burden of polluting energy sources was now so high, and made a strong case for cleaner and more sustainable energy supply, transport and food systems.
Dr Neira added that when “health is taken into account, climate change mitigation, is an opportunity, not a cost”.
She underlined the need for the world to switch to low-carbon energy sources to improve air quality and to provide additional opportunities for immediate health benefits.
She identified the burning of combustible fossil fuel as the main driver of climate change.
Dr Diarmid Cambell-Lendrum, WHO’s Coordinator, Climate Change and Health, said it was working in partnership with the global scientific and environmental community to ensure that the most vulnerable communities were protected from the negative effects of climate change.
It was important to develop earlier warning system for the climate infectious diseases and to provide resilient health care facilities.
He said looking at the economic health benefits of mitigating climate change was also critical.
He noted that when the world quickened actions in the transition to cleaner energy and kept “ourselves on track by the year 2050, we will be saving about a million lives a year, for reducing emissions alone”.
Professor Kristie Ebi, Department of Global Health and Environmental and Occupational Health Sciences, University of Washington, said the global public health community was getting impatient with the level of air pollution being caused by greenhouse emissions, and called for speeding up of actions towards addressing and mitigating the climate change.
