The U.S. healthcare system is responsible for 10% of the nation’s carbon emissions and 9% of harmful non-greenhouse air pollutants


Climate-Healthcare Can:

Decrease Energy

& Supply Costs

Health care organizations have foundational goals of improving their patients’ health, recruiting and retaining skilled staff, and managing costs, all while generating a broader benefit to their communities. Pursuing energy and material efficiency, shifting to renewable energy, and becoming resilient to natural disasters, otherwise known as Climate-Smart Healthcare, is an under-recognized opportunity for organizations to simultaneously make progress on all those foundational goals.  

Wisconsin is fortunate to have some of the worldwide individual and institutional leaders in this innovative work.

Over the last decade, Gundersen’s Envision program has made it a leader in healthcare innovation and sustainability. Envision included clean energy projects, energy efficiency solutions such as HVAC retrofitting, and waste reduction initiatives have lowered the system’s carbon and particulate matter emissions by 95% and diverted 64% of waste.  Gundersen’s cost savings from Envision surpassed $24 million in 2021 and the program and their creative waste diversion practices have made them widely popular with patients and the La Crosse community.    For instance, Gundersen donates over 500 meals a month as part of their food waste reduction program. The social and financial benefits of this program illustrate the astounding benefits climate-smart healthcare can provide.

What are the health

harms for Wisconsin?

Medical Alert, Climate Change Health

Harms for Wisconsinites include heat-related illness, worsening chronic illnesses, injuries and deaths from dangerous weather events, infectious diseases spread by mosquitoes and ticks, illnesses from contaminated food and water, and mental health problems.

The health of anyone  can be harmed by climate change, but some of us face greater risk than others. Children, athletes, pregnant women, the elderly, some communities of color, people with chronic illnesses and allergies, and the poor are more likely to be harmed.

Climate action, such as clean energy can also provide immediate health benefits for Wisconsin communities. 100% in-state clean energy production would prevent the following incidents of illness in Wisconsin each year: 1,910 premature deaths 650 respiratory ER visits 1,580 cases of acute bronchitis 49,400 respiratory symptom cases 873,000 minor restricted activity days 148,000 work loss days 34,400 cases of asthma exacerbation 670 hospital admissions 650 heart attacks. These avoided health damages cost us an estimated $21 billion annually.
