The final two columns deal with the carbon footprint of the fuel. The fourth column contains the proportion of CO 2 released when the fuel is converted for energy, with respect to its starting mass, and the fifth column lists the energy produced per kilogram of CO 2 produced. As a guideline, a higher number in this column is better for the ...
This is a list of U.S. states and territories by carbon dioxide emissions for energy use, [1] [2] as well as per capita [3] [4] and by area. [5] The state with the highest total carbon dioxide emissions is Texas and the lowest is Vermont. The state with the highest per capita carbon dioxide emissions is Wyoming and the lowest is New York.
Various governmental agencies involved with environmental protection and with occupational safety and health have promulgated regulations limiting the allowable concentrations of gaseous pollutants in the ambient air or in emissions to the ambient air. Such regulations involve a number of different expressions of concentration.
The carbon emissions (carbon footprint) produced by biofuels are calculated using a technique called Life Cycle Analysis (LCA). This uses a "cradle to grave" or "well to wheels" approach to calculate the total amount of carbon dioxide and other greenhouse gases emitted during biofuel production, from putting seed in the ground to using the fuel ...
The amount of greenhouse gas emissions from deforestation is so large that the benefits from lower emissions (caused by biodiesel use alone) would be negligible for hundreds of years. [136] [138] Biofuel produced from feedstock such as palm oil could therefore cause much higher carbon dioxide emissions than some types of fossil fuels. [143]
The scale uses the global warming potential unit, the carbon dioxide equivalent (CO 2 e), and the unit of electrical energy, the kilowatt hour (kWh). The goal of such assessments is to cover the full life of the source, from material and fuel mining through construction to operation and waste management.
An emission intensity (also carbon intensity or C.I.) is the emission rate of a given pollutant relative to the intensity of a specific activity, or an industrial production process; for example grams of carbon dioxide released per megajoule of energy produced, or the ratio of greenhouse gas emissions produced to gross domestic product (GDP).
Californian Governor Arnold Schwarzenegger issued Executive Order S-1-07 on January 19, 2007, to enact a low-carbon fuel standard (LCFS). [14] [15] The LCFS requires oil refineries and distributors to ensure that the mix of fuel they sell in the Californian market meets the established declining targets for greenhouse gas (GHG) emissions measured in CO 2-equivalent grams per unit of fuel ...
