Supply chain due diligence: Part 2 
ELISABETTA CAVALLO Independent researcher, London

This two-part report provides an overview of key considerations for the corporate and financial sector regarding supply chain due diligence, risk management and adaptation to ‘green’ practices, in light of the regulatory, industry, and socio-economic transformations on the horizon. The report also details observations on best practices in supply chains, particularly regarding the responsibility of ‘top players’ to address ESG factors beyond first tier suppliers, use leverage in the absence of contractual relationships, and to cooperate with suppliers, to achieve a more equal distribution of value along the chain. It concludes by proposing that the Covid-19 pandemic, having reinvigorated concern for an ‘inclusive, green and resilient recovery’ and driven a desire to ‘build back better’, is a salient time to redefine economic models and societal behaviours.

The German Federal Constitutional Court on the German Climate Change Act

The German Climate Change Act of 2019 aims to implement the Federal Republic’s obligations under the 2016 Paris Agreement. Young climate change activists complained that the Act violates their fundamental freedom rights in that national targets and emission reductions are regulated only until 2030 with no specification of reductions thereafter. This article examines the Constitutional Court's subsequent Order, declaring the 2019 Act to be partly unconstitutional.
