Considering environmental sustainability is of great importance to humanity, it is essential to assess whether electrical vehicles (EVs) actually contribute to improving it. The objectives of the present study are, from a macro (broad-scope) perspective, to identify the sources of emissions and to create a framework for the calculation of CO2 emissions resulting from large-scale EV use. The results show that V2G mode increases emissions and therefore reduces the benefits of using EVs. The results also show that in the best scenario (NC mode), an EV will have 32.7% less emissions, and in the worst case (V2G mode), it will have 25.6% more emissions than an internal combustion vehicle (ICV), meaning that sustainability improvement is not always ensured. The present study shows that considering a macro perspective is essential to estimate a more comprehensive value of emissions. The main contributions of this work are the creation of a framework for identifying the main contributions to CO2 emissions resulting from large-scale EV integration, and the calculation of estimated CO2 emissions from a macro perspective. These are important contributions to future studies in the area of smart grids and large-scale EV integration, for decision-makers as well as common citizens.<\/jats:p>","DOI":"10.3390\/app14146177","type":"journal-article","created":{"date-parts":[[2024,7,16]],"date-time":"2024-07-16T11:31:57Z","timestamp":1721129517000},"page":"6177","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["CO2 Emissions Resulting from Large-Scale Integration of Electric Vehicles Using a Macro Perspective"],"prefix":"10.3390","volume":"14","author":[{"given":"F\u00e1tima","family":"Monteiro","sequence":"first","affiliation":[{"name":"Polytechnic Institute of Coimbra, Coimbra Institute of Engineering, 3045-093 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0317-4714","authenticated-orcid":false,"given":"Armando","family":"Sousa","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, University of Porto, 4200-465 Porto, Portugal"},{"name":"INESC TEC\u2014INESC Technology and Science, 4200-465 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,16]]},"reference":[{"key":"ref_1","unstructured":"EDP (2015). \u00c9vora Inovcity\u2013Smart Energy Living, EDP Distribui\u00e7\u00e3o SA."},{"key":"ref_2","first-page":"5","article-title":"Integration of EVs into the smart grid: A systematic literature review","volume":"65","author":"Sultan","year":"2022","journal-title":"Energy Inf."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"201","DOI":"10.1146\/annurev-environ-031312-102947","article-title":"Smart Grids","volume":"38","author":"Palensky","year":"2013","journal-title":"Annu.
