The NSF Center for Sustainable Separations of Metals is committed to diversity, equity and inclusion across the breadth of its activities. The Center’s focus on sustainability in all its forms, as outlined in the UN Sustainability Goals, resonates with this commitment. Promoting equality and reducing inequalities for all motivate the work of the CSSM, with the recognition that fundamental contributions to environmentally sustainable separations of metals can lead to reductions in poverty, affordable and clean energy, and access to cleaner water to support good health and well-being in support of all people, particularly those who are most marginalized. Collaborations among diverse partners improve our efforts toward meeting the Center’s grand challenges, with differences being shared and celebrated to create a more robust program, well grounded in its purpose. With inclusion as a core value, spanning all dimensions of work, the CSSM welcomes all people regardless of sexual orientation, race, creed, socioeconomic background, ethnic origin, disability status or family background. An atmosphere of respect and genuine desire to make a positive difference stand as pillars supporting the critical work of the Center. Programming and efforts work toward fostering a space that is free from bias and incorporating a support network and pathways for underrepresented groups to become leaders in STEM fields.
