HEAT-SHIELD was a Horizon 2020 funded which aimed in addressing the negative impact of increased workplace heat stress on the health and productivity of five strategic European industries: manufacturing, construction, transportation, tourism and agriculture. This work has provided the most detailed methodologies to estimate health and economic implications of global warming and to assess different mitigation and adaptation options to fight climate change. By leading reports published by the WHO, WHO-Europe and ILO, we have disseminated our policy recommendations and further informed national Ministries of Labour/Health/Environment/ Social Cohesion/Migration, etc. Societal/public outreach via public (international, national and social) media have been prioritized and massive throughout the project.
