Global Warming Potential
The Global Warming Potential is an index that measures the radiative forcing of a unit mass of a given well-mixed greenhouse gas in the present-day atmosphere integrated over a chosen time horizon, relative to that of carbon dioxide.[1]
Table 1. Global warming potential for gases relevant to agriculture.
| Obs | Greenhouse gas | 20 | 100 | 500 | Description |
|---|---|---|---|---|---|
| 1 | Nitrous oxide | 289 | 298 | 153 | |
| 2 | Methane | 72 | 25 | 7.6 |
Food consumption patterns and climate change
Table 2. Greenhouse gas emissions from farm to table for 22 food items commonly consumed in Sweden.
