Humans—more specifically, the greenhouse gas (GHG) emissions we generate—are the leading cause of the earth’s rapidly changing climate. … The burning of fossil fuels like coal, oil, and gas for electricity, heat, and transportation is the primary source of human-generated emissions.
What is the biggest contributor to climate change?
Globally, the two biggest sectors that contribute to climate change are electricity generation (~25%) and food & land use (~24%). In other words, burning coal, oil, and natural gas to generate electricity is the single largest source of global emissions, but the food & land use sector is nearly tied with it.
