There鈥檚 lots of talk about how some countries emit significantly more greenhouse gases than others. But where do these numbers come from? Countries estimate these emissions by using a 鈥渂ottom-up approach鈥 - combining data on certain polluting activities with the emissions typically produced by those activities. But greenhouse gas levels are still too high. Global emissions need to fall almost 50% by 2030 if we want to avoid over 1.5 degrees of warming. Learn more in .
