In the latest issue of Geophysical Research Letters, doctoral

For Climate, Place Matters

At this point, most serious researchers agree that the average city-dweller produces fewer climate-warming emissions than a typical suburban or rural resident. City-folks tend to drive less, and walk or use transit more, than those of us who live in suburbs or out in the country. And city dwellers also tend to have less living
