  "abstract": "Background: Climate mitigation can deliver substantial air quality co-benefits, yet these remain poorly quantified across pathways ranging from sufficiency-to technology-driven transitions. This study compares four French energy-transition scenarios for 2030 and 2050 against a 2019 baseline under fixed meteorology, evaluating annual PM 2.5 and NO 2 concentration changes and health and economic co-benefits. Methods: PM 2.5 and NO 2 concentrations for 2030 and 2050 were estimated with the CHIMERE chemistrytransport model using scenario-specific emission projections. Health impacts relative to 2019 were assessed via disease-specific lag assumptions, covering yearly premature mortality, morbidity, DALYs, and economic benefits across nine cardiometabolic and respiratory outcomes (hypertension, lung cancer, acute myocardial infarction, stroke, COPD, type-2 diabetes, respiratory infections, asthma in children and adults). Findings : Annual population-weighted exposure in continental France is projected to fall by 24% (PM 2.5 ) and 45% (NO 2 ) by 2030, and by 40% (PM 2.5 ) and 75% (NO 2 ) by 2050, relative to 2019 consistently under all four 2050 transition scenarios. Health gains, assessed over each period under delayed-impact assumptions, were substantial and broadly consistent across the four scenarios. Annual avoided premature deaths are projected to reach 8,800-9,300 (PM 2.5 ) and 11,000-12,800 (NO 2 ) by 2030, rising to 21,300-22,100 (PM 2.5 ) and 24,500-26,200 (NO 2 ) by 2050. Avoided morbidity cases reached nearly 40,000 (PM 2.5 ) and 15,000 (NO 2 ) by 2030 to 68,000 (PM 2.5 ) and 20,300 (NO 2 ) by 2050, with DALYs averted increasing from nearly 150,000 in 2030 to 230,000 by 2050 across the pollutants. By 2050, direct lifetime medical cost savings reached approximately e780-810 (S4-S1) million/year for PM 2.5 and were markedly smaller for NO 2 , at approximately e60-64 million/year (S4-S1). Annual intangible cost savings (discounted to present value) totalled approximately e19-20 billion for PM 2.5 and e17-18 billion for NO 2 across S1-S4. Conclusion: Net-Zero transition can deliver substantial health and economic co-benefits across diverse policy pathways. These findings support integrating co-benefits into climate policy frameworks to strengthen the evidence base for ambitious mitigation action.",
