Climate change can have a devastating impact on our health. When people are injured or exposed to disease related to floods or fires, it's up to health systems to pick up the pieces.

But health care itself is one of the world's most carbon-intensive industries, responsible for 4.5 percent of all greenhouse gas emissions. What can health systems do to address climate change?

In the United Kingdom, the National Health Service (NHS) has set some ambitious goals to reduce its carbon footprint.

On this encore episode of The Dose, Nick Watts, the NHS's chief sustainability officer, talks about how the health service is meeting these goals, and whether its efforts could be replicated in countries like the United States. A low-carbon health care system, he says, is actually just a good health care system.
