2007 Greenhouse Gas
Emissions by Gas (percents
based on Tg CO2 Eq.)
(Tg – teragram = 1012 g)

How the U.S. compares
23.6%
Top 8 countries make 44% of CO2
CO2 concentrations at the Mauna Loa Observatory in
Hawaii (as of May 2009)
http://www.esrl.noaa.gov/gmd/ccgg/trends/co2_data_mlo.html
What about before 1960?
Mauna Loa, Hawaii
Changes in the average global temperature relative to the mean temperature
during the 20th century

http://www.epa.gov/climatechange/science/recenttc_triad.html
)
How do we remove this CO2?
• Carbon sink: is a reservoir of carbon that
accumulates and stores carbon for an
indefinite period. The main sinks are:
– Absorption of carbon dioxide by the oceans
– Photosynthesis by plants and algae to turn
the carbon into plant matter
– Injection of CO2 emissions deep into
geological subsurface
Breakdown
What is a carbon footprint?
• Carbon footprint (FP): is “the total set of
GHG (greenhouse gas) emissions caused
directly and indirectly by an individual,
organization, event or product”
(UK Carbon Trust 2008).
• Everyone in this room has a FP
Let’s determine your C-FP
