On January 20, 2025, the Trump administration ordered the termination of work-from-home arrangements for federal workers. This decision destroyed employee morale, led to mass layoffs of remote workers, and created logistical issues for federal agencies. The return-to-office mandate also has wider implications for environmental health.
One of the main benefits of working from home is reduced greenhouse gas (GHG) emissions. Climate change is one of the biggest threats facing environmental and public health in the 21st century, and reducing our carbon footprint is imperative to mitigating this risk. One study found that WFH reduces work-related carbon footprint by 58 percent, an example of a climate change mitigation approach.
Addressing climate change issues occurs from two intertwined perspectives—adaptation and mitigation. Reducing GHGs is a mitigation approach because it focuses on lessening the severity of climate change by slowing down warming. Meanwhile, adaptation focuses on alleviating the ecological and health burden associated with a changing climate. One way that working from home has adaptation benefits is that it can help reduce heat stress. A study conducted in Germany found that WFH employees had much lower perceived heat stress, which also contributed to increased productivity.
Another benefit of working from home and, thus, reducing long commute times is the reduction in air pollution. Non-electric vehicles produce hazardous pollutants such as PM2.5 (tiny particles that can get deep into the lungs), nitrogen oxides (NOx), and volatile organic compounds (VOCs). All of these different pollutants can impact your health and cause diseases such as lung cancer. A study measuring the relationship between traffic, NOx emissions, and lung cancer found that a 10-μg/m^3 (10 micrograms per cubic meter) increase in NO2 was associated with a 4 percent increase in lung cancer. Reduction in commuting traffic also means that residents living near business hubs in urban areas can enjoy cleaner air and less traffic during typical rush hour time frames.
