A carbon dioxide heat map shows the specific regions and neighborhoods that are most responsible for U.S. carbon emissions. Major cities appear as hot spots, while the Midwest and the Northeast are among the worst offenders.
More college students are seeing "green" in their futures, but it's not about money: it's about growing opportunities in sustainability.
