Abstract: Carbon-neutral design is pivotal for achieving the future energy performance targets of buildings. This paper shows research projects that promote the environmental sustainability of university campuses at the international level. GHG accounting methods and operational strategies adopted by the University of Genoa (UNIGE), Italy, and the Florida International University (FIU) in Miami, USA, are compared, with both universities striving to make buildings and campus facilities benchmarked and carbon neutral in the near future. Our comparative research includes analyzing campus buildings at both universities and their attempts to design, retrofit, and transform these buildings into carbon neutral buildings. Two case studies were discussed: the Smart Energy Building (SEB) in the Savona Campus of the UNIGE, and the Paul L. Cejas School of Architecture (PCA) Building of the FIU. The SEB’s construction reduced emissions by about 86 tCO 2 /y, whereas the PCA’s retrofitting reduced GHG emissions by 30%. Other operational strategies, including energy efficiency and energy generation, allowed the UNIGE to reduce their overall Scope 1 + 2 GHG emissions by 25% from 2013 to 2016. Globally, FIU Scope 1 + 2 GHG emissions per person were found to result in more than three times the UNIGE’s emissions, and 2.4 times if evaluated per square meter. The results were compared with GHG emissions and operational strategies from other universities.
