POLICY BRIEFS

Policy Briefs contain recommendations or visions and cover policy areas that are of interest to G20 policymakers. The majority of the Policy Briefs has been developed by a corresponding Think20 Task Force.

T20 Recommendations Reports tie related policy proposals made under different G20 Presidencies into a common policy advice framework. They aim to leverage connections between T20 research organizations as well as other stakeholders to address well-defined global problems, in order to support G20 policymakers and to aid business and civil society organizations in complementing G20 policy efforts.

    Accounting for more than 80 percent of global emissions, the role of the G20 in reaching the goals of the Paris Agreement is pivotal. But will the G20 provide the urgent leadership needed on climate action, asks Amar Bhattacharya, senior fellow for Global Economy and Development at Brookings.

  • G20 Japan: Action Plan on Energy Transitions and Global Environment for Sustainable Growth

    The G20 members have an important role in supporting the private sector in the promotion of innovation, investment, and a better business environment to develop and deploy affordable, reliable, sustainable, and low GHG emissions energy systems, and to achieve a cleaner, more resilient and sustainable future. Governments play a key role in innovation that provides clear signals and in creating an enabling environment.

  • Companies plead for a circular economy

    A group of sustainable companies including multinationals and 2000 SMEs call upon the G20 to boost demand and transparency for circular products and services. A move towards a circular economy, which is restorative and regenerative by design, presents a huge opportunity. To overcome the barriers, they call on the G20 to secure access to sustainably sourced raw materials, bio-based materials and biomass; enhance re-use, recycling and cascading; train governments in green public procurement; extend public responsibility schemes and green fiscal reform aiming at resource efficiency; and aim for increasing the uptake of high-quality secondary raw materials.

  • G20 Climate Change Commitments and Compliance

    In this research report, Brittaney Warren systemically analyses the compliance on climate change commitments made by the G20 since the first G20 summit in 2008 through to the 11th summit in 2016. One key observation is that a higher number of climate change commitments a summit makes does not correlate with high compliance on the issue overall.

  • G20 Energy Commitments and Compliance

    In this study, Brittaney Warren systemically analyzes the G20 Research Group’s database on G20 energy commitments and compliance. It finds that of the 105 energy commitments the G20 made since 2009 compliance with the 16 assessed ones was in the mid range at an overall average of 73%.

  • G20 Energy Transformation during the German Presidency

    With changing economic realities, an ambitious G20 green energy shift is overdue. In order to counter the financial stress in the fossil fuel and nuclear industries and the countries exporting fossil commodities, energy should no longer be left primarily to the G20 “Sherpa track”, but should be included prominently in the finance track. The authors of this policy brief discuss Germany’s opportunity to complete the shift during its G20 Presidency in 2017.

  • COVID-19 and the Crisis of National Development

    COVID-19’s rapid move from warning sign to global pandemic has yanked the spotlight onto a number of questions humanity has been uneasily avoiding for years. Beyond the human-focused ones like how to keep a global economy running when flights are shut down, it has also drawn attention to the human exploitation of ecosystems as national assets, which compels the human–animal interactions that probably made the virus infectious to humans in the first place.
