Document Summary
Caco3 cao + c2: process probably accounts for <5% of anthropogenic co2 emissions. Reduction of carbon sinks: deforestation: an estimated 1. 6 billion tonnes of forest material is burned each year, the annual net loss of forests worldwide each year is roughly an area the size of. Carbon sinks: the term sink" refers to a mechanism that removes co2 from the air. Key sinks are: land vegetation, ocean direct absorption. Fossil fuels: removal of carbon sinks (most importantly, forests, cement production. Key co2 source: fossil fuels: burning 1 kg of carbon creates 3. 67 kg of carbon dioxide (c + o + o, humans began burning large amounts of carbon-based fossil fuels in the late. 1700s: consumption has been accelerating in the last 50 years. Co2 source: cement production: a key ingredient in cement is limestone (caco3, to make cement requires removing the carbon from the limestone, to get at the.
