Carbon capture and sequestration (or storage)—known as CCS—has attracted interest as a measure for mitigating global climate change because large amounts of carbon dioxide (CO 2) emitted from fossil fuel use in the United States are potentially available to be captured and stored underground or prevented from reaching the atmosphere. Large, industrial sources of CO 2 , such as electricity-gener...

The United States currently meets 80% of its energy needs by burning fossil fuels to form CO2. The combustion-based production of CO2 has evolved into a major environmental challenge that extends beyond national borders and the issue has become as politically charged as it is technologically demanding. Whereas CO2 levels in the atmosphere had remained stable over the 10,000 years preceeding the...

Carbon sequestration is believed to “buy time” for technical change in the energy sector. To assess rigorously this widespread argument, we build an intertemporal optimization model where both abatement of fossil fuel emissions and biomass sequestration can be used to mitigate climate change. We confirm that permanent sequestration, if feasible, can be a cost-effective part of an overall climat...

A pilot cropland carbon sequestration program within north central Montana has allowed farmers to receive carbon credit for management adjustments associated with changing from tillage-based agricultural systems to no-till. Carbon credit can also be obtained by adopting conservation reserve, where cropland is planted into perennial vegetation. Summer fallowing is also considered within the cred...

The lack of proper wastewater treatment results in production of CO(2) and CH(4) without the opportunity for carbon sequestration and energy recovery, with deleterious effects for global warming. Without extending wastewater treatment to all urban areas worldwide, CO(2) and CH(4) emissions associated with wastewater discharges could reach the equivalent of 1.91 x 10(5) t(CO2)d(-1) in 2025, with...
