Global Emissions by Source Type

World World Energy Energy Use Continues to GrowUse Continues to Grow~85% of world energy is from fossil fuels
Fossil fuels burned for electricity generation and
transportation are the major sources of CO2 emissions

Dangers of climate change increase Dangers of climate change increase with higher global temperaturewith higher global temperature
E.S. Rubin, Carnegie Mellon Source: IPCC, 2007
More extreme events are expected More extreme events are expected as atmospheric concentration risesas atmospheric concentration risespp
The Climate Policy The Climate Policy GoalGoal
• 1992 U N F k C ti Cli t• 1992 U.N. Framework Convention on Climate Change called for “stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system”
E.S. Rubin, Carnegie Mellon
*192 countries are parties to the convention

Implication of StabilizationImplication of Stabilization
• Because GHGs have very long atmospheric lifetimes—y g ptypically measured in centuries (vs. days to weeks for other common air pollutants) —global GHG emissionsmust be reduced significantly in order to stabilize atmospheric concentrations .... no matter what stabilization target is selected
E.S. Rubin, Carnegie Mellon
Analogy: To stabilize the rising water level in a slow-draining tub, the faucets must be tightened to a trickle
Mitigating Climate Change Mitigating Climate Change Requires Requires Large Emission Large Emission Reductions, Reductions, SoonSoon
To avoid serious impacts (>2ºC rise), the IPCC assessment indicates a need for large reductions in GHGs by 2050
Required change in global GHG emissions from 2000 to 2050
–50% to –85%
E.S. Rubin, Carnegie Mellon

Motivation and Motivation and Opportunities for Opportunities for CCSCCS
• F il f l ill ti t b d f d d• Fossil fuels will continue to be used for many decades —alternatives not able to substitute quickly
• CCS is the ONLY way to get large CO2 reductions from fossil fuels used for electricity and industrial processes
• CCS also can help decarbonize the transportation sector via low-carbon electricity and hydrogen from fossil fuels
E.S. Rubin, Carnegie Mellon
• Energy models show that without CCS, the cost of mitigating climate change will be much higher
