Corporate events and sustainability: concrete criteria, not declarations

Sustainability in corporate events has become a frequent criterion in briefings, but it rarely translates into concrete measures during production. There is a significant gap between declaring that an event takes the environment into account and implementing specific criteria that genuinely reduce its impact. This gap has practical causes: sustainability criteria, properly applied, can be more expensive or more complex to manage in the short term.

Transport: the biggest impact

At a corporate event where attendees travel, air or road transport represents the most significant part of the event's carbon footprint. Centralising transport — collective buses, shared transfers from the airport — choosing venues accessible by public transport, and minimising unnecessary travel by the production team are the measures with the most real impact. Carbon offsets have marginal utility as a complement, but do not replace reduction at source.

Sustainable catering

Catering has several sustainability dimensions: the origin of the produce — local and seasonal reduces the transport footprint — reducing food waste — adjusting quantities, donating leftovers — and service materials — reusable glassware and cutlery versus disposables. Many venues have restrictions on catering suppliers, which can limit options. Before committing to a space, it is worth asking what flexibility exists to apply sustainability criteria to the catering.

Suppliers with a genuine environmental commitment

Working with suppliers and brands that have sustainability built into their own operations, not just their communications, makes it easier to apply real criteria to the event. Companies in the energy or electric mobility sectors, for example, often have internal sustainability requirements that carry over into the events they organise: recycled materials, local suppliers, impact measurement. Asking a supplier what sustainability policy applies to their own operation, not just what they can offer for the event, is a fast way to spot whether the commitment is genuine or just declarative.

Production materials

Signage, decorative elements, gifts, and printed materials are line items with avoidable environmental impact. Alternatives exist: digital signage instead of printed, reusable or rented decoration rather than items produced ad hoc, gifts from B Corp certified or fair-trade companies. The criterion for these decisions should not be solely environmental impact but also whether they reduce waste without compromising the quality of the event.

Venue certification

Some venues in Barcelona and the metropolitan area hold environmental certifications — ISO 14001, EMAS, or similar. Asking the venue about this before contracting is a first step, but does not guarantee the entire event is sustainable: it also depends on the suppliers used and the production decisions made.

Carbon offsetting: what it covers and what it does not

Carbon offsetting means funding projects — reforestation, renewable energy — that absorb or avoid an amount of CO2 equivalent to what the event generated. It is a useful complementary tool, but it has limits: it does not reduce the event's actual emissions, it depends on the quality and verification of the offset project, and some certification schemes are more rigorous than others. Before labelling an event "carbon neutral," it is worth checking which offset standard was used and whether the baseline emissions calculation is realistic.

Measuring impact

A growing number of companies request a sustainability report after the event. The minimum information for this kind of report includes the total kilometres travelled by attendees, the volume of waste generated, the kilograms of food not consumed, and whether production materials were reused or recycled. Having this information requires planning for it from the start, not trying to reconstruct it after the event.

The cost of applying sustainability criteria

Applying sustainability criteria has a cost that varies by measure. Shared transport or venues with good public transport access do not add cost, and can even save budget. Local, seasonal catering usually costs about the same as conventional catering. Where an extra cost typically does appear is in certified materials — recycled paper, reusable décor from specialised suppliers — and in impact measurement, which requires additional management time. Presenting sustainability as a set of decisions with different costs, rather than a single label, helps decide what to apply given the available budget.

The production team's perspective

Any sustainability criteria the client wants to apply must be communicated in advance to the agency and to suppliers. Changing material or catering criteria at short notice may not be feasible, or may carry significant additional cost. Sustainability that works starts in the brief, not in the décor.
