Cars cause most greenhouse emissions and love to say Fuck You to pedestrians.
The biggest source of Seattle’s greenhouse emissions, cars, love to say Fuck You to pedestrians. CHARLES MUDEDE

The Seattle Times reports that between 2008 and 2014, our city's population grew by 13 percent, and yet its greenhouse emissions dropped by 6 percent. The post gives three reasons for this decline: greater energy efficiency in buildings, increased density, and warmer winters. My guess is that the second reason (more people living in a small area) is the most important of the three. The post also points out that the decline is still far short of the city's planned "58 percent cut by 2030 over the 2008 baseline." What is preventing the city from achieving this important goal? Simply cars (or what the author of the post euphemistically describes as the "combustion of transportation fuels"). The burning of ancient dead matter for the most irrational form of urban mobility accounted for 66 percent of greenhouse emissions in 2014.
