This research demonstrates that optimizing carbon emissions and costs in precast concrete production can improve outcomes, suggesting effective green building policies.
Key Points
A 4.2% reduction in carbon emissions by 2030 is possible with a 10–20% investment in green policies.
Costs can remain optimized while reducing carbon emissions by 7.52% with a carbon tax of CNY 100/ton.
Technology optimization and energy structure pathways can achieve emission reductions of 9.68% and 8.97%, respectively.
The findings support coordinated control of emissions and costs during precast concrete production and offer practical policy guidance.
