- West Macedonia, Greece saw wintertime cardiac hospital admissions fall 22–42% between 2011 and 2021 after lignite mine and power station closures, while a rural hospital 50–100 km away saw admissions rise about 2% over the same period.
- One West Macedonia hospital recorded heart attacks and severe heart rhythm problems fall to roughly one-third of 2011 levels, alongside a more than 90% drop in wintertime sulphur dioxide approaching detection limits.
- Pittsburgh's 2016 coal processing plant closure cut sulphur dioxide by 90% and arsenic by 66%, with emergency room visits for heart problems dropping 42% immediately and continuing to decline through 2019.
- Bradford's clean air zone was followed by roughly a 25% reduction in GP visits for heart and breathing problems.
- London's ultra-low emission zone was accompanied by improved children's lung health and a 3% reduction in annual emergency admission trends for central London adults — 8% for heart problems and 6% for breathing problems.
- University of West Macedonia researchers framed the regional transition as a "microcosm of what can be achieved globally through sustained emission reductions," though a separate social attitudes survey found regional differences in how green investments were perceived.
Why it matters: Four independent natural experiments — Greek mine closures, the Pittsburgh coal plant shutdown, and clean air zones in Bradford and London — each link emission cuts to measurable cardiac and respiratory gains within years, reframing decarbonisation as a local public-health win rather than a distant global one and giving policymakers concrete data to justify further clean air measures.
