Why Carbon Capture and Sequestration
A National and Global Perspective
The science of capturing and sequestering – or storing – CO2 is growing in prominence and necessity as the nation explores ways to reduce greenhouse gas emissions and mitigate global climate change. While the nation continues to develop renewable technologies, including low or no-carbon energy sources, it is likely that sequestration is one of the few technologies available in the relatively near term at the scale necessary to reduce greenhouse gas emissions to acceptable levels. Worldwide CO2 emissions from human activity have increased from a negligible level 200 years ago to more than 33 billion metric tons annually today, according to the U.S. Department of Energy. If CO2 emissions are not reduced, the United States will emit roughly 6.8 billion metric tons of CO2 per year by 2030, exceeding 2005 emission levels by more than 14 percent, according to the U.S. Energy Information Administration. As policymakers around the world devise new energy and climate strategies, it makes sense for America and other industrialized nations to collaborate with citizens, state and local governments, and business and industry to reduce the amount of CO2 allowed into the atmosphere.
Global Climate Change
Scientists believe that CO2 is the most abundant of the man-made greenhouse gases. As a result, federal and state governments have long looked for environmentally safe ways to reduce these harmful emissions while recognizing that the use of fossil fuels is vital to our national economy, culture and security.
