The Brown to Green Report 2019 is the world’s most comprehensive review of G20 climate action. It provides concise and comparable information on G20 country mitigation action, finance and adaptation.

The strategic and well-informed inclusion of the private sector in climate change adaptation planning and activities must be a key part of all countries’ efforts to adapt to the impacts of climate change; they will be key partners in the design, financing and implementation of adaptation priorities. This study aims to offer guidance to governments and their partners on how to engage the private sector in the NAP process.

Current trends depict an irreversible momentum for a global energy transformation. Renewables have moved to the centre of the global energy landscape. Technological advances and falling costs have made renewables grow faster than any other energy source. Many renewable technologies are now cost-competitive with fossil fuels in the power sector, even before taking into account their contributions to the battles against air pollution and climate change. These trends are creating an irreversible momentum for a global energy transformation leading to shifts that will affect almost all countries and will have wide-ranging geopolitical consequences.

This report published by IRENA's Global Commission on the Geopolitics of Energy Transformation with support from the Norwegian Ministry of Foreign Affairs, the United Arab Emirates Ministry of Energy & Industry, and the German Federal Foreign Office looks into these developments from a foreign policy perspective.

The so-called Vulnerable Twenty (V20) Group was established in October 2015 with the inaugural meeting of the V20 Ministers of Finance at the Climate Vulnerable Forum in Lima, Peru. The V20 can be considered as an example of the importance of early action in the field of adaptation in order to initiate a transformative change towards resilient societies.
