Small and medium WWMs offer a potentially more sustainable alternative, but the lack of standardized life cycle assessment (LCA) approaches limits robust comparison and informed decision-making. In this study, we conduct a global harmonization of life cycle assessments of small- and medium-scale systems across 96 LCAs and 9 treatment technologies. By harmonizing life cycle inventories, we eliminate variability in methods, assumptions, and biases, thereby providing a consistent setting to compare environmental impacts. The harmonization process shows that GHG emissions have been underrepresented in inventories. The results suggest that direct emissions to air are a key contributor to climate change, and decarbonization strategies should focus on minimizing these emissions. Sequencing batch reactors showed the lowest average phosphorus and low nitrogen emissions to water with minimal chemical dosing and low direct GHG emissions to air. Our findings support the development of environmentally sustainable small- and medium-scale water-treatment solutions for municipal settings.<\/jats:p>","DOI":"10.1021\/acsestwater.6c00580","type":"journal-article","created":{"date-parts":[[2026,10,1]],"date-time":"2026-10-01T09:01:16Z","timestamp":1790845276000},"page":"6725-6738","source":"Crossref","is-referenced-by-count":0,"title":["Global Harmonization\nof Life Cycle Assessments for\nSmall- and Medium-Scale Wastewater Treatment"],"prefix":"10.1021","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-7372-291X","authenticated-orcid":true,"given":"Emilio","family":"Solis","sequence":"first","affiliation":[{"name":"Leiden University, Institute of Environmental Sciences (CML) , ,","place":["Leiden, the Netherlands, 2333 CC"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nils","family":"Thonemann","sequence":"additional","affiliation":[{"name":"Leiden University, Institute of Environmental Sciences (CML) , ,","place":["Leiden, the Netherlands, 2333 CC"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7786-3179","authenticated-orcid":true,"given":"Ranran","family":"Wang","sequence":"additional","affiliation":[{"name":"Leiden University, Institute of Environmental Sciences (CML) , ,","place":["Leiden, the Netherlands, 2333 CC"]},{"name":"Nanjing University, Institute for the Environment and Health , ,","place":["Suzhou, China, 215163"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arnold","family":"Tukker","sequence":"additional","affiliation":[{"name":"Leiden University, Institute of Environmental Sciences (CML) , ,","place":["Leiden, the Netherlands, 2333 CC"]},{"name":"Netherlands Organisation for Applied Scientific Research TNO , ,","place":["Den Haag, the Netherlands, 2595 DA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0519-6968","authenticated-orcid":true,"given":"Valerio","family":"Barbarossa","sequence":"additional","affiliation":[{"name":"Leiden University, Institute of Environmental Sciences (CML) , ,","place":["Leiden, the Netherlands, 2333 CC"]},{"name":"PBL Netherlands Environmental Assessment Agency , ,","place":["Den Haag, the Netherlands, 2594 AV"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,10,1]]},"reference":[{"key":"2026100910102686500_cit1","doi-asserted-by":"publisher","first-page":"5254","DOI":"10.1016\/j.scitotenv.2010.07.062","article-title":"Wastewater management through the ages: A history of mankind","volume":"408","author":"Lofrano","year":"2010","journal-title":"Sci.
