carbon equivalent per year (Song et al. 2002). Carbon dioxide emissions from these fossil fuel industries are from combustion gases and byproduct carbon dioxide, mainly from synthesis gas but also from other sources. There is an excess of 120 million tons per year of high-purity carbon dioxide from the exponential
There is, however, considerable evidence that gentle warming and increased carbon dioxide are beneficial to plants. Also, more people die in winter than in summer. The present level of carbon dioxide is about 390 ppm (parts per million). All plants need carbon dioxide; that is what plants use to grow: The more carbon dioxide the faster they grow.
and 5 – 6% of global carbon dioxide emissions could be used, respectively. However, there is one estimate that suggests approximately 15% of global emissions of carbon dioxide could be used per year by 203011. In terms of net carbon dioxide are likely to account for less than 1% of global emissions reduction12. For net

Carbon, Emissions and Greenhouse Gas emissions are used interchangeably and all refer to Green House Gas emissions (GHG) which are made up of Carbon Dioxide (CO 2) and other GHG's, all of which are expressed as Carbon Dioxide equivalents (CO 2e). Embodied Carbon (eCO 2): GHG emissions from materials and construction. Operating Carbon (oCO
Through the utilization of natural gas, electricity and fuel, carbon dioxide (CO2) is not the only greenhouse gas measured. Carbon dioxide equivalent (CO2e) has become the standard of measurement against which the impacts of releasing different greenhouse gases are evaluated. Carbon dioxide equivalents for various greenhouse
