Most sustainability conversations in the events industry start with venues, catering and offsetting. Travel is usually acknowledged and then set aside, because delegate and speaker travel is rarely up for debate: it is the reason onsite events happen. That instinct holds up. Business travel and accommodation typically account for 70 to 90 percent of an event's total emissions, and attendee travel is usually the single largest source within that figure. Across the industry as a whole, aggregated travel, energy, catering and logistics may account for up to 10 percent of global greenhouse gas emissions.
A smaller, less examined line sits inside that same travel budget: interpreters and technical crews, flown in and set up on-site as a matter of course, alongside soundproof booths, consoles and headsets shipped from country to country. None of that travel exists so these teams can be seen. It exists purely to make the room work, which makes it one of the more straightforward places to start cutting.
Remote interpreters, remote technicians, hybrid delivery models and reduced equipment movement are where that starts, without asking a single delegate to change how they show up.
Presence matters most where the value is relational. Delegates build partnerships. Executives read a room and adjust in real time. Sponsors want visibility. These are legitimate, business-critical reasons to fly people to a venue, and no sustainability policy should try to engineer them away.
But an event's supporting cast, the people whose job is to enable the room rather than be seen in it, is a different category. Their contribution is functional. It does not depend on physical proximity to the stage, and increasingly, it does not need to.
Conference interpreters have historically flown internationally as a matter of course, arriving with or meeting soundproof booths, consoles and headsets that then had to be freighted, installed and struck down again. Technical operators followed the same pattern: in the room, behind the booth, responsible for audio quality that delegates would never think about unless it failed.
This setup made sense when the technology to do it otherwise did not exist. Simultaneous interpretation depended on hardwired booths and line-of-sight coordination with the floor. Reliability meant physical presence, and for decades every mode of interpretation required interpreters and AV support teams on-site, at the cost of thousands of flights that did nothing to reduce emissions. That constraint shaped decades of event planning, to the point where "the interpreters are flying in" became an unquestioned line item rather than a decision anyone actively made.
That constraint has largely lifted. Remote simultaneous interpretation lets qualified interpreters work from a studio or a certified home setup anywhere in the world, connected to the event through a secure platform rather than a cable running to a booth. The same applies to technical production: audio engineers can monitor and manage feeds remotely, without shipping a booth or flying in a crew to strike it down afterwards.
Removing interpreters and technicians from the travel manifest does more than cut flights. It removes the freight and installation of physical booths, reduces the equipment that has to move between venues, and shortens the on-site build. For organisers, that is fewer logistics to manage. For the event's footprint, it is one of the more straightforward reductions available, because it does not touch the parts of the event that depend on people actually being there.
The pattern has been visible in practice for some years now. When the Inter-Parliamentary Union ran its 144th Assembly in Bali with a mixed on-site and remote interpreting team, shifting part of that team to remote delivery removed the need for up to 30 physical interpreting booths, along with the hardware that would otherwise have been freighted in, stored and struck down locally. Fewer interpreters travelling and less equipment moved translate directly into fewer flights, less freight, and a lighter technical build, without changing how delegates experienced the Assembly.
That is consistent with the broader pattern around remote participation: because it removes travel and much of the on-site energy load, delivering a role remotely can carry a fraction of the footprint of flying that same role in, with fully remote formats measured at 50 to 300 times smaller than in-person equivalents. Applied to interpreters and technical crews specifically, rather than to the audience, that reduction is available without touching the parts of the event delegates travel for in the first place.
A practical sustainability strategy starts with an honest audit of who is travelling and why. For each role on the manifest, the question is simple: does this person's contribution depend on being physically present, or does it depend on being reliably connected? Speakers, client-facing staff and anyone whose role is relational usually belong in the first group. Interpreters and technical crews usually belong in the second, and can be supported remotely without any loss of quality, provided the platform meets recognised standards for audio, redundancy and interpreter working conditions.
This is not a one-off decision. It is a default worth building into event planning from the outset, so that flying in a full language and technical team is a deliberate choice rather than an inherited habit.
