The California Climate Action Registry, which will begin operation in Fall 2002, is a voluntary registry for California businesses and organizations to record annual greenhouse gas emissions. Reporting of emissions in the Registry by a participant involves documentation of both “direct” emissions from sources that are under the entity’s control and “indirect” emissions controlled by others. Ele...

Global climate change is the main issue of discussion among scientists throughout the world. The effects are beginning to become obvious as sudden changes of the weather conditions in many regions have been occurred the last years. Greenhouse gases, including carbon dioxide, are responsible for this change. One of the main sources of carbon dioxide emissions is the electrical power generation f...

The combustion of fossil fuels has increased carbon dioxide in the atmosphere, and the oceans have annually absorbed an equivalent of 20-30% of the carbon dioxide in fossil-fuel emissions. The present annual uptake by the oceans of approximately 1.8 billion tons of carbon (26% of global fossil-fuel emissions in 2003) is well constrained, has slightly acidified the oceans and may ultimately affe...

During the production of concrete, cement, water, aggregate, and chemical and mineral admixtures will be used, and a large amount of carbon dioxide will be emitted. Conversely, during the decades of service life of reinforced concrete structures, carbon dioxide in the environment can ingress into concrete and chemically react with carbonatable constitutes of hardened concrete, such as calcium h...

Northern peatlands are important contributors to the global carbon cycle. In cold and moist climatic conditions, boreal peatlands have sequestered large amounts of atmospheric carbon during the past few thousand years (GORHAM 1991). The carbon balance in mires depends on the rates of photosynthesis and respiration which are affected by both the long-term and the short-term variations in environ...
