For years, environmental sustainability has been a priority for many industries. Health care lagged behind on this issue, but that’s starting to change.

Health care is a mission-driven industry. We care about our communities, our reputation, and the role we play within society. We care about attracting and retaining staff and patients. And most importantly, we care about our patients’ well-being.

Working toward environmental sustainability fits with health care’s mission. The health care sector knows it needs to do better, but the challenge is understanding how to change. And as governmental or regulatory action is starting to require organizations to hit emissions or waste-reduction targets, leaders need to act now to avoid financial penalties.

Almost all health care leaders want to be part of the solution. However, it’s difficult for leaders to link their conscious behaviors to the downstream, slow-moving, and complex effects of climate change. It’s even harder to understand or acknowledge the subconscious behaviors that contribute to climate change in equal measure.

These conscious and subconscious behaviors make all the difference. Efforts to reduce climate change are regularly deprioritized in favor of other events, pressures, or priorities. We’ve come across many excuses for why health care hasn't done enough to tackle climate change, but three stand out:

• Climate change is too far off to worry about.
• Climate change isn’t health care’s problem.
• Investments in environmental sustainability may not yield any return.

What leaders need to understand is that every one of those statements is false.

The conventional wisdom detailed on the previous page accounts for much of why health care is lagging so far behind other industries when it comes to powerful messages and actions against climate change. And cognitive biases are a big part of that conventional wisdom. These biases among health care leaders are preventing the large-scale behavioral changes necessary for health care organizations to make significant commitments to and investments in environmental sustainability.

The first step to changing the status quo is moving subconscious biases into the conscious realm.

Health care leaders need to acknowledge that these subconscious biases are universal and be aware of when they affect actions. Letting go of deeply held beliefs is critical to making progress on an issue as complex and long term as climate change.

In his book The Evolving Self, Robert Kegan describes the process of bringing often unconscious beliefs into conscious awareness as flipping the “subject-object relationship.” He states that we are not conscious of our beliefs, we are subject to them. But by bringing our beliefs into conscious awareness, those beliefs become like objects which we can look at and assess for their value to what we are trying to accomplish. In doing so, we can move from unconscious reaction to conscious decision. In essence, that means changing one’s mindset surrounding these cognitive biases from “I am them” to “I have them.” And that will allow people to make decisions that can lead to better environmental sustainability.

To mitigate the risks of human biases in preparing for or dealing with exogenous threats like climate change, we must start by looking at the main biases that stand out.

In this research, we examine three cognitive biases that contribute to health care’s lack of action against climate change. This list is by no means exhaustive—we selected the biases we think are most powerful in preventing leaders from committing to action or investment. We’ve also provided diagnostic questions to help you see what this looks like in your organization and some exercises to help you get out of each way of thinking.
