Image:Greenhouse Gas by Sector.png

From Wikipedia, the free encyclopedia


This figure shows the relative fraction of man-made greenhouse gases coming from each of eight categories of sources, as estimated by the Emission Database for Global Atmospheric Research version 3.2, fast track 2000 project . These values are intended to provide a snapshot of global annual greenhouse gas emissions in the year 2000.

The top panel shows the sum over all man-made greenhouse gases, weighted by their global warming potential over the next 100 years. This consists of 72% carbon dioxide, 18% methane, 9% nitrous oxide and 1% other gases. Lower panels show the comparable information for each of these three primary greenhouse gases, with the same coloring of sectors as used in the top chart. Segments with less than 1% fraction are not labeled.


This figure was prepared by Robert A. Rohde from publicly available data and is part of the Global Warming Art project.
