Sustainability in a broad sense: An essential aspect of scientific conferences.

This article reflects on sustainability in the context of scientific conferences with emphasis on environmental, diversity, inclusivity, and intellectual aspects. We argue that it is imperative to embrace sustainability as a broad concept during conference organization. In-person conferences have an obvious environmental impact but mitigating strategies can be implemented, such as incentivizing low-emission travel, offering fellowships to support sustainable traveling, and promoting use of public transport or car-pooling. Utilizing eco-conscious venues, catering, and accommodations, along with minimizing resource wastage, further reduces environmental impact. Additional considerations include facilitating hybrid format conferences that allow both in-person and online attendance. Hybrid conferences enhance global participation whilst reducing resource consumption and environmental impact. Often-overlooked benefits can arise from the simple recording of talks to enable asynchronous viewing for people unable to attend in person, in addition to providing a legacy of knowledge that, for example, could support the training of early career researchers (ECRs) or newcomers in the field. The longevity of a research field, intellectual sustainability, requires an inclusive conference atmosphere, offering optimal opportunities for ECRs, minority groups, and researchers from emerging countries. Diversity and inclusivity not only enrich conference experiences but also enhances creativity and innovation.
