Introduction to the governance of
Solar Radiation Modification
This topic aims to offer the audience basic information about Solar Radiation Modification (SRM) approaches and the need for their governance. It seeks to answer the following questions:
- What is SRM and why do we need to talk about its governance now?
- What are important SRM approaches, how might they work, what are potential benefits and risks?
- What are the governance challenges around SRM?
- How might some of the governance challenges be considered or addressed in the context of current governance processes and mechanisms?
Webinars
This Webinar will feature three ten-minute expert overviews of solar radiation modification approaches, and the governance challenges they raise. It will be followed by a half hour moderated Q&A session, during which audience members will be invited to submit written questions via the Zoom chat. Speakers include:

Campfire Chat
This Campfire Chat aimed to provide insights into diverse viewpoints on the governance of SRM (presented in the webinars above), in a relatively informal, moderated, semi-structured discussion between experts. Audience members were invited to suggest topics via the Zoom chat. Guests included:
Arunabha Ghosh / India

He is lead author of Jobs, Growth and Sustainability: A New Social Contract for India’s Recovery (CEEW, 2020). He is the co-author/editor of four books: The Palgrave Handbook of the International Political Economy of Energy (2016); Energizing India: Towards a Resilient and Equitable Energy System (SAGE, 2016); Human Development and Global Institutions (Routledge, 2016); and Climate Change: A Risk Assessment (FCO, 2015). Arunabha’s essay “Rethink India’s energy strategy” in Nature was selected as one of 2015’s ten most influential essays.
Arunabha advises governments, industry, civil society and international organisations around the world. This has included India’s Prime Minister’s Office, several ministries and state governments. He was invited by France, as a Personnalité d’Avenir, to advise on the COP21 climate negotiations; and also advised extensively on HFC negotiations. He served on the Executive Committee of the India-U.S. PACEsetter Fund. He has been a member of Track II dialogues with ten countries/regions; and formulated the Maharashtra-Guangdong Partnership on Sustainability. He is a member of the Environment Pollution (Prevention & Control) Authority for the National Capital Region.
His monthly columns in the Business Standard (Inflexion Points) and the Hindustan Times (Over The Horizon) are widely read. He has hosted a documentary on water in Africa, featured in National Geographic and Discovery Channel documentaries on energy, and delivered a TED Talk on air quality. He is a World Economic Forum Young Global Leader, member of WEF’s Global Future Council on Energy, and an Asia Society Asia 21 Young Leader. He holds a D.Phil. from Oxford and topped Economics from St. Stephen’s College, Delhi.
Jesse Reynolds / United States of America
Dr. Jesse Reynolds is a scholar of international environmental policy. He researches and teaches how society can develop norms, rules, procedures, and institutions to manage environmental opportunities and challenges, particularly those involving new technologies. While his approach is centered within international environmental law, he draws upon other disciplines, including international relations and economics. Dr. Reynolds has extensively researched geoengineering (climate engineering), a group of proposed methods to intentionally intervene in earth systems at large scales in order to counterbalance anthropogenic climate change. His book The Governance of Solar Geoengineering: Managing Climate Change in the Anthropocene was recently published on Cambridge University Press. Dr. Reynolds is also currently exploring the roles of new biotechnologies, such as gene drives, and artificial intelligence in the conservation of biodiversity and facilitating sustainability more generally. He is an Emmett / Frankel Fellow in Environmental Law and Policy at the Emmett Institute on Climate Change and the Environment of the University of California, Los Angeles School of Law. He is also an associate researcher at the Utrecht Center for Water, Oceans, and Sustainability Law, Utrecht University and a research affiliate at Harvard’s Solar Geoengineering Research Program, Harvard University.

Moderator: Kai-Uwe Barani Schmidt / Germany
Kai-Uwe Barani Schmidt builds on more than 20 years of international and senior level working experience including at the executive office of the secretary-general of the United Nations, at the secretariat to the United Nations Framework Convention on Climate Change, at the World Bank Institute, and independent senior advisory work.
As a senior member of the secretary-general’s Climate Change Support Team, Schmidt contributed to the coordination of the global climate change summit in 2009 and was part of the secretary-general’s team at UNFCCC negotiations in Copenhagen. In the lead-up to and during the landmark Paris climate change agreement in 2015, he led the team’s work on the global climate action agenda, initiated by the secretary-general at his 2014 summit, that mobilized thousands of companies, hundreds of cities, and sub-national authorities in collaboration with governments, the UN, IGOs, and NGOs.
Over the last few years, Schmidt has contributed to the launch of the Initiative for Climate Action Transparency (ICAT). This initiative aims to build a best practice for guidance, tools, and capacity of governments and sub-national authorities to measure the effects of their policies with regard to climate change and the other UN SDGs and report progress publicly, thus fostering greater transparency, effectiveness, and trust, enabling innovative financing and ambition in climate policies worldwide.
Schmidt’s experience has covered public policy design, regulatory design, and implementation of global emissions trading and offset instruments. He has coordinated high-level events, navigating the interface of international negotiations with private sector, intergovernmental, and non-governmental organizations focusing on private sector engagement in climate change and development action at international, national, sub-national, city, and company/NGO levels. In addition, Schmidt’s experience has covered institutional build-up and management of both resources and people.
C2G strives to achieve a diversity of views and backgrounds across all its events. To that end, it is always open to feedback and suggestions regarding future participants and topics, to ensure a range of perspectives by sector, gender, race, geography, age and other dimensions. It will not always achieve the necessary diversity in all circumstances due to issues of availability and familiarity, but aims over time to expand the range of contributors able to address its issues, subject to the broad principles outlined in its mission statement.
