20 Mar 2023 --- Inconsistent data access and a lack of supply chain transparency are the key barriers to gaining credibility on environmental sustainability claims, finds a new report by Smurfit Kappa. The findings, drawn from 440 senior business leaders in 11 global economies, show that only 11% of companies have robust sustainability strategies in place. The report, titled The transparency edge, comes as rising consumer demand, political pressure, new regulatory requirements, and investor expectations are tightening environmental sustainability standards throughout the packaging sector.
