However, the environmental sustainability of this goal has not been assessed comprehensively on a life cycle basis. Focusing on the electricity sector, which contributes >40% to China's GHG emissions, this study evaluates the role and the potential of renewables for achieving net-zero by estimating their life cycle impacts across 31 provinces in China. A future (2050) renewable electricity grid is designed considering daily demand and generation curves, as well as resource potential and future technological advancements. Most of the electricity is generated by solar and wind (70%), followed by hydro (9%), biomass with and without carbon capture and storage (6%), and energy storage (14%). This mix achieves a net-negative climate change impact of −12 kg CO<sub>2</sub> eq./MWh electricity generated (compared to the current 877 kg CO<sub>2</sub> eq./MWh). The net negative impact is found in 18 provinces (−2.1 to −166.1 kg CO<sub>2</sub> eq. per MWh) owing to the biomass energy with carbon capture and storage (BECCS). The rest of the provinces have a net-positive but still relatively low impact (0–42 kg CO<sub>2</sub> eq./MWh) because of the high share of renewables. The majority of the remaining 17 impacts are also significantly lower (5.5–96%) than the impacts of the current grid, except for metal depletion, water consumption and freshwater and marine ecotoxicity. The minimum requirements for achieving the net-zero target for the electricity sector are either the utilisation of 55% of the total estimated biomass energy potential of 22 EJ, or BECCS share of 46% in the total capacity of biomass plants, equivalent to 2.25% of electricity generation. These results help to identify the environmental trade-offs in meeting the decarbonisation targets and to guide a future deployment of net-zero electricity in China.</div></div>","PeriodicalId":48619,"journal":{"name":"Sustainable Production and Consumption","volume":"64 ","pages":"Pages 151-177"},"PeriodicalIF":9.6,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147386124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results reveal that mechanical recycling consistently delivers the lowest climate change impact, achieving net-negative emissions (−1.22 to −0.67 kg CO₂-eq/kg PLA), while chemical recycling without repolymerisation performs worst (up to 0.58 kg CO₂-eq/kg PLA). Burden shifting is observed in all pathways, with terrestrial ecotoxicity for composting increasing by 31% and water consumption for recycling rising by up to 49% under ambitious climate scenarios. Normative environmental learning rate analysis reveals that maintaining 2025 impact levels across categories requires annual learning rates of 5–14% for recycling and < 12% for composting and incineration, rates considered feasible.

However, the involvement of non-EU battery producers and recyclers makes that such requirements may not effectively stimulate domestic recycling due to cross-border trade flows. To examine this issue, this study develops a dynamic material flow analysis to project global demand and end-of-life volumes of lithium, cobalt, and nickel from EV batteries. Based on these projections, recycled material flows are traced across six stages from retirement to reuse, distinguishing whether processes occur within or outside the EU. The effectiveness of the regulation is then assessed using the minimum battery collection rate required for compliance. Results indicate that under the business as usual (BAU) scenario, EU demand for lithium, nickel, and cobalt will increase from 17.0 kt, 86.8 kt, and 13.0 kt in 2031 to 25.8 kt, 131.3 kt, and 19.7 kt in 2040.

Building sufficient cathode material production capacity within the EU is crucial for achieving the recycling targets, as it represents the key link for utilizing recovered materials.
