Air pollution is shaving months — and in some cases more than a year — off your life expectancy, depending on where you live, according to a study published Wednesday.

Worldwide, outdoor air pollution reduces the average life expectancy at birth by one year. The effect is much more pronounced in some countries: It cuts the average Egyptian’s life span by 1.9 years and the average Indian’s by 1.5 years. In Russia, it’s around nine months.

For the United States, it’s less, currently reducing the life expectancy of an American born today by a little more than four months on average.

Those findings come as the Trump administration is proposing a loosening of pollution controls from coal-fired power plants.
