How to talk with clients about sustainability
Many structural engineers hesitate to raise sustainability with clients, expecting it to be a hard sell. In practice, the conversation goes better when it's framed around the client's own priorities rather than presented as a separate agenda. Below are some practical approaches.
Lead with what the client already cares about. Few clients are moved by carbon numbers alone, but most care about cost, schedule, risk, marketability, and meeting code. Many embodied carbon reductions align directly with these - reducing material quantities saves money, and right-sizing a structural system can simplify construction. Frame sustainability as a way to serve goals the client already has, not as an add-on.
Raise it early. The biggest carbon reductions come from decisions made at the start of design - structural system, material selection, grid layout. These are also the decisions that are expensive to revisit later. Bringing sustainability into early conversations, when options are still open, is far more effective than proposing changes once the design is fixed.
Be specific about what's low-cost and what isn't. Build credibility by distinguishing the changes that carry little or no premium (lower-carbon concrete mixes, optimized member sizing, specifying EPDs) from those that involve real tradeoffs. Clients trust an engineer who is candid about cost more than one who presents everything as free.
Use benchmarks to make it concrete. Abstract carbon figures are hard to act on. Comparing a project against typical values for similar buildings - or showing the reduction from one design option to another - gives clients something tangible to weigh. This is where reporting frameworks and benchmark data become useful in the room.
Connect it to where the market is going. Code requirements, procurement standards, and owner expectations increasingly account for embodied carbon. For clients with public, institutional, or corporate stakeholders, a lower-carbon structure can support reporting obligations and reputational goals. Framing sustainability as forward-looking positions the client well rather than asking them to take on extra burden.
Meet resistance with options, not pressure. If a client is hesitant, offer choices rather than pushing a single position. Presenting two or three design options with their carbon and cost implications lets the client stay in control of the decision while still seeing the lower-carbon path clearly.
The throughline is that sustainability conversations work best as part of the normal engineering discussion - cost, constraints, and good design - rather than as a separate pitch.
