Health care, veterinary, and research facilities produce tremendous amounts of waste and account for a significant proportion of their institutions' energy and water use. The majority of municipal solid waste produced by these facilities gets unsustainably disposed of, including exportation to lower-income countries, and most of the plastic waste is nonrecyclable and nondegradable. The produced waste not only results in excessive carbon emissions harming planetary health but also poses direct harm to human health, broadens global inequities, and produces avoidable economic costs. Greening up laboratories by reducing waste production and water and energy use offers many benefits and does not have to be time or resource intensive. Sustainable practices to green up laboratories include reusing materials, decreasing energy use by choosing low-energy settings and shutting off equipment when not in use, installing low-flow faucets to decrease water use, proper sorting of waste, environmentally conscious purchases of supplies, and avoiding unnecessary medical and veterinary tests.
