Health-centered climate action is now imperative in a world facing irreversible harm from a contest that pits convenience and commercial interest against
sustainability goals. Science shows how human demands exceed the earth’s regenerative capacity, causing an ecological overshoot and pushing humanity and
the ecosystem closer to multiple ecological tipping points. According to the World Meteorological Organization, >30 gigatonnes of CO2 are released into the
Earth’s atmosphere every year, mostly from fossil fuels, non-renewable energy production, and polluting human activities contributing GHG that cause climate
change. As the world grapples with these ecological crises, it’s clear some responses over the past 50 years have fallen short of achieving desired impact. Slow
interventions to fast-moving crises do not seem to work, thus increasing climate-related losses and damages amidst slow adaptation. However, the good news
is that several of these tipping points are interrelated, and action to starve off one will also ameliorate others.

Since anthropogenic ecological overshoot is a major cause of the myriad symptoms around the globe today, changing basic human behaviour must now come
first and fast. Mitigation can keep temperatures within adaptability thresholds while delivering health co-benefits in the immediate term. Increasing access to
zero-carbon energy, if delivered with health as a priority, will not only reduce energy poverty but also improve air quality and avert millions of deaths. A shift
to electric mobility can avert 460,000 deaths yearly from travel-related PM2·5 emissions. These gains would reduce demand for healthcare services, helping
to minimize healthcare-related emissions and their impacts.
