China now No. 1 CO2 offender

WASHINGTON


All three studies examine emissions of carbon dioxide from the burning of fossil fuels such as coal. Energy usage is the most significant man-made source of carbon dioxide, which accumulates in the atmosphere and traps heat.

Unless China sharply cuts its emissions, “the situation is pretty bleak,” says Richard Carson of the University of California, co-author of a study in today’s Journal of Environmental Economics and Management. “There’s a lot less time to do something than people previously thought.”
