Call for Session Proposals

Call for Sessions Closed

The call for session proposals is now closed. If you have submitted a session proposal, thank you! The CEC21 Steering Commitee will be in touch in April to inform you of their decision. 


Deadline March 2, 2020.

The Institute for Advanced Sustainability Studies (IASS) is organising a third international conference to contextualise discussions of “climate engineering” approaches alongside other interventions into global systems in response to climate change ( CEC21 aims to bring together research, policy and civil society communities’ perspectives from around the world. The conference will be held in Berlin, Germany in spring 2021. It will address all approaches historically aggregated under the term “climate engineering”, and additionally aims to contextualise them among other proposed responses to climate change, including mitigation, adaptation, de-growth, rewilding and ecological restoration. The conference aims to situate these topics within the wider context of societal transformations towards sustainability.

The conference will address natural scientific, technical, ethical, and social aspects of these responses to climate change, via disciplinary research, interdisciplinary collaboration, and transdisciplinary engagement.

  • In disciplinary research, specific questions are addressed from a single disciplinary perspective at a high level of specialization and depth.
  • In interdisciplinary research, specific questions are addressed in collaboration with multiple disciplines.
  • In transdisciplinary engagement, new approaches that merge more traditional disciplinary perspectives with input from different stakeholder communities, such as academics, NGOs, the media, industry and policymakers, provide new frameworks for discussing issues of collective interest and relevance.

The call for session proposals is the first of three ways of registering to participate at CEC21, inviting interested stakeholders (academics and non-academics alike) to submit their ideas for sessions. Secondly the CEC21 Steering Committee will issue a call for contributions to invite interested parties (academics and non-academics alike) to read through the list of accepted sessions and submit ideas for how they could contribute to a given session. Finally, the CEC21 Steering Committee will open registration for non-contributing participants on a first-come-first-served basis.

Sessions may have up to 3 conveners, and up to two additional suggested contributors. Proposals for interactive session formats are strongly encouraged, as are inter- or transdisciplinary proposals. Session proposals that promote panel diversity, in terms of gender, career stage, political perspective, geography, and sector (academia, policy, and/or civil society), are strongly encouraged. Key aims are to reflect the heterogeneity of the field and to better understand how interventions into global systems in response to climate change intersect with each other and with mitigation and adaptation strategies. The Steering Committee is able to provide suggestions for co-convenors and/or contributors to help improve session diversity. Please contact for help sourcing diverse co-convenors and/or contributors for your session. Session conveners are strongly urged to choose one of the more interactive session formats from the list provided here. Alternative suggestions for innovative session formats are welcome. The deadline for session proposals is March 2, 2020.

Session submissions will be subject to anonymised peer review, with each session being reviewed by at least two members of the Steering Committee and the Advisory Group. Sessions will be selected based on quality, proposed format, thematic fit and available slots. The Steering Committee will inform prospective conveners about the acceptance of session proposals by the beginning of April, 2020. Successful conveners will be invited to register for CEC21.

Please note that throughout the conference all participants are limited to two participatory roles. A participatory role includes convening a session, co-convening a session, contributing to a session, presenting a poster, speaking in a plenary etc. The Steering Committee aim to ensure a wide variety of views are represented and hence select sessions in a way we deem fitting for a diverse representation. The Steering Committee reserves the right to reject, adjust, select and propose to mix, match and merge sessions.
