C2G Mission

C2G seeks to catalyse the creation of effective governance for climate-altering technologies, in particular for solar radiation modification and large-scale carbon dioxide removal.



In implementing its mission, C2G follows and encourages use of the following principles:

  • Impartiality: C2G is impartial regarding the potential use of any proposed climate-altering technologies or interventions. These are choices for society to make.
  • The need for governance: Governance is more than governments: it includes interlocutors from across all sectors of society, coming together in diverse processes to discuss, learn, share knowledge and take decisions at multiple levels. C2G works with governments, intergovernmental processes and non-state actors, encouraging them to consider the governance of climate-altering technologies for the international policy-making agenda.
  • Rule of international law: C2G affirms the need for urgent climate action on many fronts, guided by the precautionary principle and science and addressing all potential measures to manage the increasing risks posed by climate change. This includes the implementation of existing multilateral agreements, in line with the sustainable development agenda: such as the Rio Declaration on Environment and Development, the UN Framework Convention on Climate Change including its Paris Agreement, the Convention on Biological Diversity, the UN Convention on Desertification and Land Degradation, the Montreal Protocol and the 2030 Agenda for Sustainable Development.
  • A broad risk management approach: C2G encourages society-wide discussions about the risks, trade-offs, synergies and potential benefits of climate-altering technologies. These discussions should consider both the risks of action — and inaction — in a rapidly warming world. To that end, C2G supports the importance of research that is governed in accordance with the highest standards, expands knowledge for the benefit of all, and supports informed decision-making by global policy makers.
  • Preparedness: Society will need to make difficult decisions on how to respond to the climate crisis today and the not so distant future – decisions that could have profound consequences for all of humanity both today and tomorrow. In addition to decisions to deliver urgent emissions reductions, this includes various options to remove massive amounts of carbon from the atmosphere to reach net negative emissions. Society may also potentially consider the possibility of cooling the planet by reflecting sunlight back into space, though technologies to do this on a large scale are still theoretical, controversial, and pose significant risks and governance challenges.
