The UN Climate Change Report 2007 at a Glance

CO2-Reduction Potential
per Business Sector (8/10)

When discussing the costs of fighting global warming, scientists and economists often point to the importance of finding the most-effective and cheapest ways to reduce greenhouse gases. The UN panel offers a kind of roadmap showing how much GHG emissions (they use the term CO2 equivalent) could be saved at a given price for one ton of GHG emissions in which business sector. GHG emissions could be reduced in buildings – even at the relatively low cost of 20 US dollars per ton of GHG. Agriculture also has a huge potential for GHG reduction, but only if emissions prices rise to a staggering 100 dollars per ton of GHG (Graphic: IPCC).
