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 ...
Talk to your kids about why our carbon footprint matters in kid-friendly terms. Opting for other transport methods like walking or cycling to school will lower emissions, save money and improve ...
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 ...
Energy efficiency is not strictly necessary to achieve zero carbon housing, so long as the house is able to cover its electricity demand with renewable energy generated on site. However, greater energy efficiency reduces the scale of renewable generation required, and the cost of electricity imported, and may increase comfort by reducing ...
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]
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.

A Zero-Energy Building (ZEB), also known as a Net Zero-Energy (NZE) building, is a building with net zero energy consumption, meaning the total amount of energy used by the building on an annual basis is equal to the amount of renewable energy created on the site [1] [2] or in other definitions by renewable energy sources offsite, using technology such as heat pumps, high efficiency windows ...
