Senior living homes across Maryland are making efforts to go green. A 2022 study found that seniors in wealthy countries were on track to become the highest contributors of greenhouse gas emissions as compared to other age groups. The study found that in countries like the U.S. where many seniors live in older single-family homes, consumption of energy increases. But there are ways to mitigate that, and many senior communities in Maryland are taking steps to become more sustainable and climate-friendly.
