COP24 special report on health and climate change

3-14 December 2018, Katowice, Poland - In its latest report, WHO highlights health as the biggest issue to be prioritized during COP-24 and provides key recommendations to the negotiators on how to maximize the health benefits of tackling climate change and avoid the worse health impacts of this global challenge. Although there has been hugely positive progress in tackling health and climate change issues, there is a still a long way to go. Millions of people are still exposed to air pollution globally, resulting in 7 million premature deaths every year; 3 billion people still lack access to clean and reliable energy; and nearly a quarter of all deaths worldwide result from people having to live or work in unhealthy environments. Unless significant changes are made and stronger action taken, we are risk of failing to meet the targets of the Paris Agreement and the SDGs.

Healthy housing for a sustainable and equitable future – the WHO Housing and health guidelines

27 November 2018 – WHO launches the first guidelines on housing and health at the 15th International Conference on Urban Health in Kampala, Uganda. The WHO Housing and health guidelines highlight the increasing impact of housing conditions on human health in light of urban growth, climate and demographic changes. The guidelines provide evidence-based recommendations relevant to inadequate living space (crowding), low and high indoor temperatures, injury hazards in the home, and accessibility of housing for people with functional impairments. In addition, the guidelines identify and summarize existing WHO guidelines and recommendations related to housing, with respect to water quality, air quality, neighbourhood noise, asbestos, lead, tobacco smoke and radon.

Leaders from national and city governments, intergovernmental organizations, civil society, philanthropy, research and academia considered the scientific evidence on air pollution and health and emphasized the urgent need for bold and prompt action to address this health crisis.

WHO Director-General's open letter to mayors on World Cities Day

Dear mayors of the world,

Former US President Lyndon B Johnson once said, “When the burdens of the presidency seem unusually heavy, I always remind myself it could be worse. I could be a mayor.” Johnson’s quote describes perfectly the enormous responsibility mayors have, but also the opportunity you have to change the lives of billions of people living in your cities.
Now, those lives are under threat by an invisible but beatable enemy that is right under your noses: air pollution. Nine out of 10 people in the world breathe polluted air, and air pollution in many places is still getting worse.

More than 90% of the world’s children breathe toxic air every day

Geneva, 29 October 2018 – Every day around 93% of the world’s children under the age of 15 years (1.8 billion children) breathe air that is so polluted it puts their health and development at serious risk. Tragically, many of them die: the World Health Organization estimates that in 2016, 600,000 children died from acute lower respiratory infections caused by dirty air. A new WHO report on Air pollution and child health: Prescribing clean air examines the heavy toll of both ambient (outside) and household air pollution on the health of the world’s children, particularly in low- and middle-income countries. The report is being launched on the eve of WHO’s first ever Global Conference on Air Pollution and Health.

International lead poisoning prevention week of action, 21-27 October 2018

From 21 to 27 October 2018 the international lead poisoning prevention week of action will take place, with a particular focus on eliminating lead paint. Lead poisoning is preventable, yet the Institute for Health Metrics and Evaluation has estimated that, based on 2016 data, lead exposure accounted for 540 000 deaths and 13.9 million years lost to disability and death due to long-term effects on health, with the highest burden in developing regions.
Of particular concern is the role of lead exposure in the development of intellectual disability in children. Even though there is wide recognition of this problem and many countries have taken action, exposure to lead, particularly in childhood, remains of key concern to health care providers and public health officials worldwide.

Third Global Conference on Health and Climate Change, 16-17 October 2018

29 August 2018 – The SIDS Initiative has a vision that by 2030, all health systems in SIDS will be resilient to climate variability and change. PAHO, jointly with WHO, will convene the Caribbean meeting of the geographically dispersed III Global Conference on Health and Climate Change: Special Focus on Small Island Developing States (SIDS) in St. George's, Grenada, from 16-17 October 2018. The conference will be attended by Ministers of Health, Ministers of Environment, partner agencies, and stakeholders from Caribbean SIDS, who will discuss and identify actions and indicators for an Action Plan on Health and Climate Change to be implemented in the Caribbean.
