Voluntary programs and emissions revisited: What is the effect of EU trade agreements with environmental provisions?

Multinational enterprises operating global value chains are being increasingly pressured to source from suppliers that adopt green private standards. Likewise, public policymakers are also pressured to reduce national pollution levels to contribute to sustainable development initiatives. In this context, while there is extensive debate on how domestic, country-specific environmental regulations interact with private standards (adopted by firms) in reducing national pollution levels, less is known about the role of international trade policies, which have recently embraced an array of sustainability issues. Our paper seeks to extend our understanding of the extent to which ISO environmental certifications affect a country’s level of emissions of greenhouse gases and air pollutants, and whether the European Union’s environmental protection (EP) standards – as mediated through trade agreements – condition this response. Prior research provides mixed evidence on the impact of the adoption of ISO-14001 on pollution reduction. Based on prior literature and using institutional theory and environmental stewardship perspectives, we expect that membership of trade agreements with EP provisions would complement the effect of ISO-14001 uptakes in reducing national pollution levels. Our arguments and results emphasize the complexity between private and public regulations on pollution reduction.
