The findings are presented in units of global warming potential per unit of electrical energy generated by that source. 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 ...
The carbon footprint explained Comparison of the carbon footprint of protein-rich foods [1]. A formal definition of carbon footprint is as follows: "A measure of the total amount of carbon dioxide (CO 2) and methane (CH 4) emissions of a defined population, system or activity, considering all relevant sources, sinks and storage within the spatial and temporal boundary of the population, system ...
In addition, the choice of energy used to heat, cool, and power homes makes a difference in the carbon footprint of individual homes. [59] Many energy suppliers in various countries worldwide have options to purchase part or pure "green energy" (usually electricity but occasionally also gas). [60]
Measurable energy conservation and efficiency gains in the 1980s led to the 1987 Energy Security Report to the President (DOE, 1987) that "the United States uses about 29 quads less energy in a year today than it would have if our economic growth since 1972 had been accompanied by the less- efficient trends in energy use we were following at ...
[89]: 71 Planners and civil engineers can construct new buildings using passive solar building design, low-energy building, or zero-energy building techniques. In addition, it is possible to design buildings that are more energy-efficient to cool by using lighter-coloured, more reflective materials in the development of urban areas.
Occupational carbon emissions relate to the amount of carbon dioxide emitted into the atmosphere from the direct use of energy to run the building e.g. the heating or electricity used by the building over the year. In the Carbon Profiling Model these emissions are measured in BER’s (Building Emission Rate) in kg of CO 2 /m 2 /year.
