Climate change is now recognised as a truly existential threat to civilisation and life on earth. And international arbitration, like all other human activities, contributes to the production of carbon emissions and, therefore, can and should also be managed with the objective of reducing these as much as reasonably possible. In most sectors, reducing carbon emissions is accompanied by a corresponding increase in costs, but this does not need to be the case with arbitration. On the contrary, reductions in emissions can be achieved through greater use of technology and procedural efficiency that are likely not only to reduce costs but may also lead to higher overall party satisfaction with how disputes are resolved. This article sets out some of the steps that have already been taken in this direction, and what more can be done by arbitration institutions, arbitrators, counsel, and the parties themselves to further reduce carbon emissions associated with arbitration. By setting an important example, arbitration stakeholders are also likely to influence further change within the global business, legal, and government communities in which they tend to occupy leadership roles.
