| Zero emission classifications | Concenpts |
|---|---|
| IC = 0 | Full decarbonization or reducing net CO2 emissions from energy and industrial processes(after accounting for CCS) to zero |
| NC = 0 | Crabon neutrality or net zero CO2 emissions |
| E = 0; EFC = 0; BFC = 0; IA = 0; LS = 0 | Zero carbon emissions everywhere |
| NGHG = 0 | Climate neutrality or net GHG emissions |
