Climate-related events unevenly affect society, worsening mental health disparities among vulnerable populations. This paper highlights that lesbians, gays, bisexuals, transgender, queers, and other individuals identifying as sexual and gender minorities (LGBTQ+) could be considered a climate-vulnerable population in the Philippines, one of the most climate-vulnerable countries. As such, this paper elucidated that LGBTQ+ Filipinos can be marginalized in climate response efforts due to their sexual orientation and gender minority identities. According to the minority stress theory, discrimination against LGBTQ+ individuals may predispose them to mental health problems. Thus, there is a need to institute an LGBTQ+ inclusive mental health response for climate-related events to address discrimination against LGBTQ+ individuals and uphold their mental health.
