It's been a long slog to get to this election day. We all know the campaigns spent millions to get their messages across. But Bob Grant at The Scientist wondered about the environmental cost (log-in required)—specifically how much the campaigns of Sens. Barack Obama and John McCain contributed to global warming. Based on total campaign expenditures—including flying, driving, and printing materials—Grant (with help from consultant Standard Carbon) estimates that the Obama camp emitted nearly 78,000 tons of climate-change inducing carbon dioxide (CO2) and the McCain campaign roughly 59,000 tons of CO2.
Standard Carbon suggests planting 18 square miles of new trees to offset that climate change pollution—the growing trees would theoretically soak up an equivalent amount of CO2—but such carbon offsets don't address the core of the problem: burning fossil fuels.
