The IPCC in April 2022 effectively gave their final warning that if we want to limit global warming, deep emissions reductions across all sectors must commence immediately. Science based targets are a way to help organisations with a clearly-defined path to reduce emissions, in line with Paris Agreement goals. Such targets include the downstream impact of supply chains. The fashion industry, perhaps with an implicit alignment to the Paris agreement, talks about the use of Science-based targets in their industry HERE and how this can help with greenwashing. The same lessons can be applied to other manufacturing supply chains.
