The intrinsic links between climate change and the COVID-19 pandemic have elevated global calls for policymakers to take immediate action on both fronts. Fiscal stimulus supporting recovery from the pandemic can be designed to simultaneously address climate change. In turn, this could help reduce the spread of future pandemics as climate change is a threat multiplier for pandemics. Destruction of the environment and biodiversity makes pandemics more likely while pollution and other man-made factors driving climate change weaken the health of human beings, raising their vulnerability to viruses and other diseases.
