Monitoring data from January to August 2023 indicate that alkanes, alkenes, alkynes, and aromatics—especially acetylene, propane, ethane, ethylene, n-butane, and toluene—account for 55.52% of total VOC concentrations. Seasonal peaks are observed, with ozone rising in summer due to enhanced photochemical reactions, and VOCs increasing in winter due to heating-related emissions. High-reactivity VOCs, particularly ethylene and toluene, contribute disproportionately to ozone and secondary aerosol formation. A coupling model integrating DeepSeek AI-based source identification and a convection-diffusion solver in Mathematica was developed to simulate compound transport dynamics and evaluate emission-reduction scenarios. A carbon compensation mechanism was embedded to assess the economic feasibility of net-zero CO₂ goals. Model results suggest that under current control strategies, regional emissions could achieve net-zero emissions by 2038, with an estimated compensation cost of USD 11.2 billion. This research highlights the synergistic nature of VOC and CO₂ control in terms of emission behavior and policy response and provides a transferable modeling approach for joint air quality and carbon management in industrialized regions.

compounds (VOCs) and carbon dioxide (CO₂) in Tiexi District, Shenyang, a representative heavy industrial city in Northeast China. Monitoring data from January to August 2023 indicate that alkanes, alkenes, alkynes, and aromatics\u0026mdash;especially acetylene, propane, ethane, ethylene, n-butane, and toluene\u0026mdash;account for 55.52% of total VOC concentrations. Seasonal peaks are observed, with ozone rising in summer due to enhanced photochemical reactions, and VOCs increasing in winter due to heating-related emissions. High-reactivity VOCs, particularly ethylene and toluene, contribute disproportionately to ozone and secondary aerosol formation. A coupling model integrating DeepSeek AI-based source identification and a convection-diffusion solver in Mathematica was developed to simulate compound transport dynamics and evaluate emission-reduction scenarios. A carbon compensation mechanism was embedded to assess the economic feasibility of net-zero CO₂ goals. Model results suggest that under current control strategies, regional emissions could achieve net-zero emissions by 2038, with an estimated compensation cost of USD 11.2\u0026nbsp;billion. This research highlights the synergistic nature of VOC and CO₂ control in terms of emission behavior and policy response and provides a transferable modeling approach for joint air quality and carbon management in industrialized regions.\u003c/p\u003e","manuscriptTitle":"Collaborative evaluation and control of CO2 and VOCs in Shenyang based on Deepseek optimization","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-09-26 09:31:48","doi":"10.21203/rs.3.rs-7540275/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"455e1414-1d89-4d3e-98ab-1d89941ae388","owner":[],"postedDate":"September 26th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"posted","subjectAreas":[],"tags":[],"updatedAt":"2026-01-21T11:51:53+00:00","versionOfRecord":[],"versionCreatedAt":"2025-09-26 09:31:48","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-7540275","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-7540275","identity":"rs-7540275","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
