Assessment of Emission Reduction Potential and Economic Feasibility for China's Offshore Wind Power Industry Based on the CCER Mechanism

• • In 2020, the offshore wind sector achieved significant CO2 emission reductions, but without CCER subsidies, the projected 2025 financial deficit risk emerges, indicating a critical dependency on carbon credit revenues for economic sustainability. • • The largest air pollutant reduction is for nitrogen oxides (NOx), while sulfur dioxide (SO2) reduction provides the most substantial co-benefits, quantified through emission inventories and grid factors. • • Economic feasibility analysis for 2020 and 2025 shows profitability when CCER revenues are included, but the levelized cost of electricity (LCOE) and market carbon pricing dynamics are decisive factors. • • Coastal provinces with advanced economies demonstrate higher potential for offshore wind development, driven by infrastructure and policy advantages, as evidenced by provincial emission reduction disparities.
