Where do greenhouse gas emissions come from?
A simple guide to how much different sectors contribute to global warming.
“A lot of places — it’s complicated,” is a perfectly reasonable answer, so it’s understandable that most people don’t have this info at their fingertips. One 2014 study found that people tend to overestimate the effects of some of the more obvious and visible sources, like vehicle exhaust and deforestation, but largely overlook the effects of meat and dairy production.
Trying to account for all of the greenhouse gases around the world is no small task, and it’s not just CO2: it’s methane, ozone, refrigerants, and a variety of other gases and particles that contribute to warming the planet, all of which are tracked by the UN’s Intergovernmental Panel on Climate Change (IPCC).
