Socio-environmental governance is not an area of exclusive government action. Corporations, investors, civil and consumer organizations are reinventing themselves as political players in an increasing number of self-regulatory arrangements. Private environmental governance covers a wide-range of schemes such as Corporate Social Responsibility (CSR), Environmental, Social and Governance (ESG) criteria; Voluntary Sustainability Standards (VSSs) and certifications. Private initiatives have been praised for their potential to contribute to the goals of the Paris Agreement. Nonetheless, the current situation in Brazil shows that the private sector has a role to play not only in making its own environmental commitments, but in demanding that governments respond.
