who emits the most greenhouse gases per capita?
china
the kyoto protocol is the most prominent international agreement on climate change, and is also highly controversial. some argue that it goes too far or not nearly far enough in restricting emissions of greenhouse gases. another area of controversy is the fact that china and india, the world's two most populous countries, both ratified the protocol but are not required to reduce or even limit the growth of carbon emissions under the present agreement even though when listed by greenhouse gas emissions per capita, they have rankings of 121st largest per capita emitter at 3.9 tonnes of e and 162nd largest per capita emitter at 1.8 tonnes of e respectively, compared with for example the u.s. at position of the 14th largest per capita e emitter at 22.9 tonnes of e. nevertheless, china is the world's second largest producer of greenhouse gas emissions, and india 4th (see: countries by greenhouse emissions). various predictions see china overtaking the us in total greenhouse emissions between late 2007 and 2010, and according to many other estimates, this already occurred in 2006.

rail transportation emits about 0.2 pounds of greenhouse gases per passenger mile (55 g/km) when each car is filled with 50 passengers. this figure increases to about 0.5 pounds per passenger mile (140 g/km) when only filled with half that amount. these numbers are still much lower than those of jet transportation, about 1 pound per passenger mile (280 g/km), and that of a solo car driver, about 1.15 pounds per passenger mile (325 g/km). even the fuel efficient prius emits more greenhouse gases per passenger mile.
