Gender issues have become a sustainable development goal under the UN auspices. Gender assessment projects are more likely to face gender differences and create corresponding policies, legislations, or treatments. Shortcomings in gender assessment projects include the impact of environmental issues on gender studies. Recently, natural disasters and air pollution incidents have been frequent. The environmental field has gradually focused on gender and environmental issues. However, domestic and foreign environment-related gender assessment projects primarily use organisational gender structure, gender income, and political participation rates as the primary assessment items. They lack environment-related gender assessment projects. This study collected 100 related studies, which were filtered into 89 articles, comprehensively integrating four assessment dimensions, eight perspectives, and 16 assessment projects. Further, through a questionnaire survey and analytic hierarchy process AHP) analysis, the study determined the key factors of an environmental-related gender assessment project. The key factors were working environments and climate change, especially related to occupational disease and high-temperature disease, emphasising mortality and prevalence rates. Therefore, gender assessment projects should prioritise establishing assessment projects and statistical indicators of the working environment and climate change perspectives and implement them in corresponding gender and environmental policies, legislations, or disposals.
