This pie chart shows annual world greenhouse gas emissions, in 2005, by sector. Emissions are measured as a percentage of total world carbon dioxide equivalent emissions:
<ul><li>Electricity and heat, 24.9%</li>
<li>Industry, 14.7%</li>
<li>Transportation, 14.3%</li>
<li>Agriculture, 13.8%</li>
<li>Land use change, 12.2%</li>
<li>Other fuel combustion, 8.6%</li>
<li>Industrial processes, 4.3%</li>
<li>Fugitive emissions, 4.0%</li>
<li>Waste, 3.2%</li></ul><p>Emissions due to land-use change include both emissions and absorptions (i.e., processes that both add to and remove carbon from the atmosphere). Emissions due to land-use change are highly uncertain.
