Table 2 Future changes in the carbon emission reduction potential of new highway tunnels under different scenarios
From: Rising carbon emissions from expanding highway tunnels and reduction pathways in China
Scenario | Total carbon emissions from highway tunnels in 2023 (100 Mt) | Total carbon emissions from highway tunnels in 2030 (100 Mt) (without considering emission reduction measures) | SCA | Total carbon emissions from highway tunnels in 2030 (100 Mt) (after emission reduction) | Carbon reduction (100 Mt) | Emission reduction rate (%) |
|---|---|---|---|---|---|---|
Baseline scenario | 5.184 | 11.034 | 1.21 | 9.163 | 1.871 | 16.95 |
High-reduction scenario | 1.00 | 9.488 | 1.546 | 14.01 | ||
Low-reduction scenario | 0.90 | 9.638 | 1.396 | 12.65 |
