“The best way to reduce your carbon footprint is to be more environmentally friendly.”—Dr. James Andrews, author of the forthcoming book “The Best Way to Save Energy in Public Transportation”The most expensive public transportation system in the country is Chicago Public Transit.

    If you drive or ride your bike to work, you’re probably paying $10 or more per hour.

    The system charges for this transportation and has one of the highest carbon footprints in the U.S. The city’s $20 billion annual operating budget includes $3.2 billion for transit, $5 billion for buses, $4 billion for rail, and $2 billion on other forms of public transportation.

    It also includes $300 million in annual subsidies for local governments, including $50 million to fund commuter rail, $60 million for mass transit, and nearly $100 million to help pay for streetcars and light rail.

    Chicago’s transit system is the most expensive in the nation, according to a recent report by the American Public Transportation Association.

    According to the report, Chicago ranked 49th out of 55 major U.N. member cities for per-capita carbon emissions per passenger mile traveled, with the highest rate at 27.5 percent.

    Chicago is also the only major U,S.

    city to rank in the top 10 for the number of greenhouse gas emissions per capita.

    Chicago has also ranked among the worst cities for green infrastructure in the United States.

    In fact, the city ranks among the 10 worst cities in terms of its carbon footprint for public transportation systems.

    That’s not surprising given the city’s climate-related pollution and air quality issues.

    Chicago ranks No. 1 in CO2 emissions per resident, behind New York City and Los Angeles.

    The number of residents living in the city who report experiencing respiratory or other health problems due to chronic pollution has tripled since 2010, according the UMass-Lowell Center for Environmental Health Research.

    In 2018, a survey of nearly 9,000 adults in the region found that 42 percent of residents report experiencing chronic respiratory issues, compared with 23 percent in 2016.

    “It is a serious health problem,” said Dr. Jim Andrews, an environmental health expert and professor of environmental health at the University of Massachusetts-Lowe.

    “There is no doubt that there is significant environmental damage from the high levels of pollution in Chicago.

    That has been a persistent problem.”

    As a result of these chronic issues, Chicago’s carbon footprint has risen from 4.2 percent of the U
