Environmental health research requires a critical understanding of sex and gender. Understanding how environmental health issues are connected to sex and gender, as well as how they are used to promote political positions related to sexual orientation and gender identity, are critical to promoting environmental health among marginalized groups.
Gender refers to sociocultural norms, identities, and relations that: 1) structure societies and organizations; and 2) shape behaviors, products, technologies, environments, and knowledge (Schiebinger, 1999). Gender attitudes and behaviors are complex and change across time and place. Importantly, gender is multidimensional (Hyde et al., 2018; Dubois et al., 2025) and intersects with other social categories, such as sex, age, socioeconomic status, sexual orientation and ethnicity (see intersectionality. Gender is distinct from sex (Fausto-Sterling, 2012). Historically, gender definitions have been based on a binary concept – women and men. In most key UN definitions, this binary framework continues to dominate, including in chemical policy. To avoid exclusions, newer definitions and guidelines often additionally use the term “all genders”. Beyond defining gender, applying a binary concept within the difference approach to Gender Mainstreaming remains valuable, productive and necessary, as it allows for comparing the experiences of women and men. Analyzing these differences and using binary-disaggregated data provides insights into social structures and inequalities. While we often work with binary categories for analytical purposes (also in chemicals management), we want to do so with a clear awareness of their limitations and with the aim of building more inclusive approaches in the future.
The empowerment of women and girls concerns their gaining power and control over their own lives. It involves awareness-raising, building self-confidence, expansion of choices, increased access to and control over resources, and actions to transform the structures and institutions that reinforce and perpetuate gender discrimination and inequality. This implies that to be empowered they must not only have equal capabilities (such as education and health) and equal access to resources and opportunities (such as land and employment), but they must also have the agency to use these rights, capabilities, resources, and opportunities to make strategic choices and decisions (such as is provided through leadership opportunities and participation in political institutions).
In addition, UNESCO explains, “No one can empower another: only the individual can empower herself or himself to make choices or to speak out. However, institutions including international cooperation agencies can support processes that can nurture self-empowerment of individuals or groups”.
Inputs to promote the empowerment of women should facilitate women’s articulation of their needs and priorities and a more active role in promoting these interests and needs. Empowerment of women cannot be achieved in a vacuum; men must be brought along in the process of change. Empowerment should not be seen as a zero-sum game where gains for women automatically imply losses for men. In empowerment strategies, increasing women’s power does not refer to “power over” or controlling forms of power, but instead to alternative forms of power—“power to,” “power with,” and “power from within”—that emphasize the use of individual and collective strengths to achieve common goals without coercion or domination.

Intersectionality describes overlapping or interdependent systems of discrimination related to age, disabilities, ethnicity, gender, geographic location, sex, socioeconomic status, sexuality, etc. Gender should not be considered in isolation. Gender identities, norms, and relations shape and are shaped by other social attributes (Buolamwini & Gebru, 2018).
An adjective describing a person who does not identify exclusively as a man or a woman. Non-binary people may identify as being both a man and a woman, somewhere in between, or as falling completely outside these categories. While many also identify as transgender, not all non-binary people do. Non-binary can also be used as an umbrella term encompassing identities such as agender, bigender, genderqueer, or gender-fluid.
Sex refers to biology; however, there is no single, universally agreed-upon set of guidelines for defining sex. Sex is complex, dynamic, context-dependent, and interacts with gender and other social factors (Ritz & Greaves, 2022; Dubois et al., 2025).
In humans (and non-human mammals), sex traditionally refers to the biological attributes that distinguish male, female, and/or intersex according to functions that derive from the chromosomal complement (generally XX/XY), reproductive organs (internal and external genitalia), or specific hormonal, environmental, or cultural factors that affect the expression of phenotypic traits (Barresi & Gilbert, 2023; Jones, 2018; Kessler, 1998).
