The term carbon neutral describes any process that over its duration and the lifespan of its products results in absorbing the same amount of environmentally damaging carbon compounds (primarily CO 2 ) as it releases into the atmosphere. Carbon neutral products and processes are designed to reduce emissions of carbon and sequester any residual emissions. Those processes that release net positive amounts of CO 2 to the atmosphere are known as carbon positive , and processes that absorb more CO 2 from atmosphere than they produce are known as carbon negative. Global climate change is the consequence of uncontrolled emissions of greenhouse gases, including CO 2 , methane, and nitrogen oxides. Biomass (e.g., trees and vegetation) may be carbon neutral if over their life cycle, burning them or converting them to fuel releases the same quantity of carbon into the atmosphere as they absorbed from the atmosphere through photosynthesis. However, ...
