GWPværdier
GWPværdier, standing for Global Warming Potential values, are a crucial metric used to quantify the climate impact of different greenhouse gases. These values represent how much heat a greenhouse gas traps in the atmosphere over a specific time period, compared to carbon dioxide (CO2). CO2 is used as the baseline, with a GWPværdier of 1.
Gases with higher GWPværdier contribute more significantly to global warming per unit mass. For example, methane
The time horizon used is important; GWPværdier are typically reported for 20, 100, and sometimes 500 years.
These values are essential for greenhouse gas inventories, climate modeling, and the development of climate policies
