Emissions accounting forms a pillar in the benchmarking of the industrial decarbonisation process. We have seen last time the categorisation (the scopes) of emissions. The relative contributions to these scopes vary from industry to industry. Today we discuss some of these variations based on the 2022 report published by the World Economic Forum.
The industrial sector accounts for about 30% of today’s global carbon emissions (excluding scope 3 emissions). Six sectors – oil, natural gas, steel, cement, aluminium and ammonia – take 80% of the share (without scope 3). The proportions of scopes 1, 2 and 3 of these sections are.
| Sector | Scope 1 (Gt CO2e) | Scope 2 (Gt CO2e) | Scope 3 (Gt CO2e) |
| Oil | 3.2 | 12.3 | |
| NG | 2.1 | 7.6 | |
| Steel | 2.6 | 1.1 | 0.7 |
| Cement | 2.4 | 0.2 | 0.8 |
| Aluminimum | 1.08 | 0.03 | |
| Ammonia | 0.45 | 0.04 | 0.8 |
