The Earth is in the midst of a climate crisis and ecological emergency. Our human brain mapping research activities play a part in driving these problems, from the energy used in our neuroimaging analyses, to our travel footprints (Rae et al., preprint). However, as professional scientists, we are also in the well-placed and privileged position to assess - and therefore address - our climate and ecological responsibilities (Aron et al., 2020).

In the context of increasing global recognition that all citizens and societies must take action on protecting the environment, we founded the OHBM Sustainability and Environment Action Special Interest Group (SEA-SIG), with the aim of addressing the environmental impact of neuroimaging research activities. Since 2020, we have grown from 25 petition-signers for registering the new SIG, to a Committee of 12 members and 3 working groups, numbering nearly 50 human brain mappers, all working to raise awareness on and ultimately reduce the environmental footprints of neuroimaging research.

Our first working group, the Neuroimaging Research Pipelines team, is tackling sustainability in neuroimaging research pipelines, by working towards integrating sustainability tools such as carbon trackers in common neuroimaging tools like fMRIPrep, and benchmarking popular pipelines on their environmental footprints. Ultimately, we aim to propose best practices for sustainable neuroimaging, including dataset re-usage and open science workflows (follow our progress on the Neuroimaging Research Pipelines working group GitHub).. Our Annual Meeting working group is campaigning to make the OHBM meeting more sustainable, from improving conference centre practices, to reducing the carbon-intensive aviation that comes with international in-person meetings by considering alternative formats such as hybrid. Our third working group, the Education and Outreach team, is developing educational resources to enable the human brain mapping community to understand how we can make our research and academic lives more sustainable, and seeking to involve neuroimagers in ongoing work and discussions around these crucial issues.

With the online OHBM 2021 Annual Meeting being our first outing as a new SIG, we were delighted to have the opportunity to share our work with OHBM colleagues and how they can make a difference, through our series of SEA-SIG events.

Our OHBM 2021 activities started with our Open Science Room panel discussion on ‘Saving time and resources: Open science and sustainability’, hosted by the OS-SIG. This was attended by over 100 neuroimagers who were keen to find out ways in which open neuroimaging is already helping save the planet - such as by 'Reducing, Recycling, and Reusing’ data - but also where we need to refine practices and procedures - such as by addressing the fossil fuel energy costs of open repository data centres, and whether to share raw data, intermediary preprocessing files, or end-stage results.

Our flagship symposium ‘How Can Scientists Respond to the Climate Emergency? A guide from the SEA-SIG’ came to the Planet Brain main auditorium the next day. Our speakers were five activist-academics who have been campaigning for sustainability in research, conferences, universities, and teaching. We were lucky to be joined by a special guest, climate scientist Milan Klower, who told us, ‘it’s happening, it’s us, it’s bad, we can fix it’ - outlining in no uncertain terms just how much of an emergency we really are in - from floods in Europe to wildfires in Australia and heatwaves in the USA - but that if we act quick, we can prevent the most catastrophic outcomes of runaway climate chaos.

We then turned to taking action in science and academia. I covered environmental issues in neuroimaging research pipelines, such as the energy consumption of big data analysis, while Anne Urai highlighted the huge carbon footprint that (pre-Covid) in-person international conferences entail - using data from Milan Klower’s excellent assessment of different meeting formats, and their carbon costs (Klower et al., 2020). One key statistic is that meeting online - as we did at OHBM2021 - cuts a conference’s carbon footprint by 99.99% compared to an international in-person meeting, equating to thousands of tonnes of CO2 - although of course we need to consider many other intersectional factors in meeting format, such as accessibility and impact on different career stages (see Sarabipour et al., 2021).

Next, Adam Aron recounted his campaign to electrify the energy supply at the multi-campus University of California, and get the institution off fracked methane gas, a highly polluting fossil fuel. Adam highlighted ‘the responsibility of all of us in our institutions, to push our institutions’, from representation on university Senates, to petitioning for pension and finance divestment from fossil fuel companies, and the banks that support them. Finally, Clare Kelly described her personal journey in facing up to the gravity of the climate and ecological emergencies, and no longer able to sit on the sidelines, developing a revolutionary inter-disciplinary module for undergraduates at Trinity College Dublin on the psychology of the climate crisis. Equipping the next generation of university graduates with a deep understanding of the psychological drivers of climate change and barriers to action is critical. Clare flagged that all of us can incorporate these issues in our teaching, such as by using climate and environmental examples in our statistical demonstrations.

We much enjoyed discussing the questions raised by audience members in the symposium chat, which ranged from the differential impact of low-carbon conference models on early career researchers versus established colleagues, to whether it is down to us to take action or solving environmental crises is the role of governments (of course it’s both!).

One of our responsibilities as professional scientists is to reduce the footprint of the annual meeting, in particular by lowering emissions from members flying to OHBM. Our roundtable discussion 'What should a sustainable post-Covid annual meeting look like?’ sought to hear views and feelings on potential alternative meeting formats, from fully online, to hybrid, biennial (meeting every other year), hub (in which attendees travel to their nearest regional ‘hub’), and more. Although everyone at the roundtable recognised the urgent need to reduce our conference transport emissions, we noted that the session was attended by only some demographics (for example, those with existing interests in this area) - and so we plan to continue these conversations more widely with Council, staff in the Executive Office, and the membership at large. Our Annual Meeting working group is currently using feedback from the roundtables to inform these conversations and dialogues, including a report for OHBM Council on a sustainable vision for the annual meeting going forwards. Do get in touch with us to share your thoughts on how we can best reduce the annual meeting’s footprint, while enabling us to connect deeply and meaningfully internationally and at all career levels.

Together with the Brain-Art SIG, we launched a competition for neuro-artists to design a new SEA-SIG logo, the winner of which was announced at our social: many thanks to Judith Bilgorai for our gorgeous new identity, now in use on our Twitter account and website! During our social we also enjoyed watching some environmental short films together, and connecting with neuroscientists around the world on sustainability. We find that hearing others care about these critical issues too is a very helpful and cathartic antidote to the barrage of bad news on the environmental catastrophes we face.

With that in mind, we are really looking forward to Glasgow 2022, and continuing our work to engage OHBM members in conversation around what we need to do to save the planet - and ourselves. We’re planning a new symposium, another roundtable discussion, and a plant-based picnic in the park - plus hybrid activities too, as we are keen to support and facilitate the participation of colleagues who aren’t able to travel in person. It will be my only in-person OHBM meeting until 2026, as I stopped flying for environmental reasons seven years ago.

We plan on sharing tips and advice on getting to Glasgow via train, wherever possible, because travelling by train rather than plane saves up to 90% of the carbon emitted by flying (Le Quéré et al., 2015). We also hope to set up a train-based social and networking scheme, so OHBM attendees can enjoy each other’s company en route. In the meantime, if there is a green initiative you think SEA-SIG, or OHBM more widely, should be working on, do get in touch.
