Resultats<\/h2>\n\n\n\n

La Universitat de Barcelona realitza un inventari de les seves emissions de gasos amb efecte d’hivernacle<\/a> com a entitat adherida al Programa d’Acords Voluntaris de reducci\u00f3 d’emissions de l’Oficina Catalana de Canvi Clim\u00e0tic de la Generalitat de Catalunya.<\/p>\n\n\n\n

Les emissions totals s’han redu\u00eft significativament en aquest per\u00edode, principalment gr\u00e0cies a la contractaci\u00f3 d’electricitat procedent de fonts renovables, a la disminuci\u00f3 progressiva del consum d’energia i aigua, i a la implantaci\u00f3 de mesures que permeten reduir la generaci\u00f3 de residus, millorar-ne la separaci\u00f3, i disminuir el consum de paper. Les emissions associades a la rec\u00e0rrega de gasos refrigerants als equips de climatitzaci\u00f3 s\u00f3n estables els darrers cinc anys, i es deriven del manteniment dels equips existents.<\/p>\n\n\n\n

Les emissions relacionades amb el transport in itinere (PDI i PTGAS) i de clients i visitants (alumnat), reflecteixen els efectes de la pand\u00e8mia de COVID-19 els anys 2020 i 2021. Aix\u00ed i tot, les emissions per la mobilitat obligada de la comunitat universit\u00e0ria de l’any 2022 i posteriors s\u00f3n prop d’un 20% inferiors a les de 2019.<\/p>\n\n\n\n

Progressivament, s’han anat incorporant nous components a l’inventari, per donar compliment a la metodologia de l’UNE-EN ISO 14064-1:2019. A partir de 2018 es van comen\u00e7ar a calcular els viatges de negoci, des de 2020 el tractament d’altres residus, des de 2022 els serveis al n\u00favol i la producci\u00f3 d’electricitat adquirida, i des de 2023 els viatges de programes de mobilitat internacional de l’alumnat i les emissions dels prove\u00efdors de la UB. Aquests nous components han anat afegint emissions a l’inventari que dificulten la comparaci\u00f3 des de l’inici de la s\u00e8rie temporal (2017), sumant-hi unes 11.000 tones de CO\u2082 equivalent.<\/p>\n\n\n\n
