Protecting human health and the environment remains a central consideration in chemical selection and substitution. There is also growing interest in understanding how broader sustainability attributes, such as carbon-emission and water-related impacts, can support decision-making. How can these impacts be measured? Which metrics and approaches are the most useful for chemical selection? And can they be applied in a consistent and practical way across sectors and value chains?
This OECD workshop will bring together experts from government, industry, academia and international organisations to discuss how carbon- and water-related considerations can be integrated into chemical selection and substitution decisions. Building on previous OECD work, participants will review existing methodologies, share experiences, and explore opportunities for greater alignment in the definitions, metrics and parameters used to assess these attributes.
Discussions will focus on identifying practical approaches that can be used alongside safety considerations to better understand the wider sustainability implications of chemical choices. The workshop will also explore the extent to which more consistent approaches can be developed and identify priorities for future OECD work in this area.
