C2G Advisory Group

The C2G Advisory Group was established to guide the initiative in its mission to catalyse the creation of effective governance for emerging climate technologies.

The Advisory Group is constituted from leading international experts covering a wide range of sectors and countries, selected to ensure deep insight into key issues relevant to achievement of the C2G mission.

Advisory Group members provide advice on the substantive issues behind the work of C2G. They provide independent strategic guidance and support to help ensure the initiative’s work is well informed, effective, and high impact. Members participate in the group in an individual, independent capacity and do not represent any specific organisation or institution. As the Advisory Group is not a decision-making body, the members have no direct and accountable influence over the work of the initiative.

Ambuj Sagar, Vipula and Mahesh Chaturvedi Professor of Policy Studies, Department of Humanities and Social Sciences; Head, School of Public Policy, Indian Institute of Technology Delhi / India

Ambuj Sagar is the Vipula and Mahesh Chaturvedi Professor of Policy Studies and the founding Head of the School of Public Policy at the Indian Institute of Technology Delhi.

Ambuj’s interests broadly lie at the intersection of technology and development. His recent work has focused on innovation policy for meeting sustainability and inclusivity challenges, energy innovation policy and strategies (in areas such as biofuels, clean cookstoves, coal power, automobiles, and institutional mechanisms such as climate innovation centers), climate change policy and politics, capacity development, higher education policy, and the technology-society interface. He has been a consultant/advisor to various Indian Govt. ministries as well as many multilateral and bilateral agencies.

Ambuj did his undergraduate studies in Mechanical Engineering at IIT Delhi. He subsequently received an M.S. in Aerospace Engineering from the University of Michigan and then an M.S. in Materials Science, a Ph.D. in Polymer Science, and an M.S. in Technology and Policy from the Massachusetts Institute of Technology.

“While technologies are a powerful vehicle for addressing societal challenges, their deployment also can come with significant, often unanticipated, environmental, health, social, and other risks.  There also is a possibility of a moral hazard where the existence of a technological ‘solution’ may then reduce or preclude efforts to reduce the underlying risk (or disregard many of the equity consequences of the technology’s deployment).  Therefore an effort to start a deep ex-ante engagement with such issues in the context of geoengineering, which in many ways epitomizes many of these concerns, is timely and much needed.”

“Barring a global economic catastrophe, it does not seem credible that the world will meet its current target of limiting atmospheric warming by 2°C, let alone 1.5°C, through conventional mitigation alone. The feasibility and wisdom of deliberate interventions in the climate system to meet present goals raise fundamental issues about humanity’s relationship with climate, the goals that we set for ourselves, and the means by which we pursue them.”
