The GWP value of a gas molecule depends on how stable the gas molecule is, how much infrared (IR) radiation it absorbs, and where along the spectrum the absorption peak lies. The IR spectrum of carbon dioxide has a strong absorption band consisting of many overlapping peaks. This band, ...
GWPs are values that allow direct comparison of the impact of different GHGs on Earth’s warming by comparing their ability to absorb the energy and how long they remain in the atmosphere compared to CO2. Carbon dioxide is taken as thegas of referenceand given a 100-year GWP ...
Embodied carbon is the measurable greenhouse gas emissions of an infrastructure's entire construction, maintenance and demolition processes. Unlike operational carbon, which measures a structure's emissions based on energy use during its occupancy, embodied carbon provides that structure's carbon footprint...
CO2e is calculated by multiplying the emissions of each of the six greenhouse gases by its 100 year global warming potential (GWP) (source: www.carbontrust.com). "What is a Carbon Footprint?"- Definition: So the simple definition of carbon foot print is: - “A measure of the amount ...
The impact of each type of greenhouse gas is collectively measured in terms of its Global Warming Potential (GWP). This metric compares the heat-trapping ability of a gas to that of carbon dioxide over a particular period of time. CO2e measurements help to show the overall impact of all ...
Global Warming Potential (GWP): provides a shared unit of measurement to compare the climate impacts of different GHGs. Quantifies the amount of energy that the emissions of 1 ton of a GHG will absorb over a period of time, relative to CO2. The time period for GWPs is typically 100 year...

This lack of speci- ficity can be problematic because different gases have varying levels of global warming potential (GWP) and different lifetimes in the atmosphere. For instance, while CO2 is the most prevalent GHG, its long-term impact is more enduring than shorter-lived but highly ...
This metric compares the heat-trapping ability of a gas to that of CO2 over a particular period—for instance, over 20, 100 or 500 years. For example, the 100-year GWP of CH4 is approximately 28–36 times that of CO2. Carbon dioxide The most abundant of the GHGs, CO2 emissions ...
(A gas such as CH4 has a different Global Warming Potential (GWP) from CO2, based on its heat-trapping ability and lifetime in the atmosphere; the number graphed here is the estimated amount of CO2 equivalent to that of all GHGs emitted, based on GWP calculations for various gases such ...
