This means taking concerted and effective action to reduce CO2 emissions and maximize energy efficiencies. Forward thinking healthcare CEOs are making a strong business case for energy efficiency as a cornerstone of their sustainability policies. They are also considering the economic, social and even personal impacts of their practices. As a result, healthcare thought leaders have adopted a broad, systems-thinking approach to sustainability. The result: energy management now sits side-by-side with clinical and financial governance.
