We are building a rail-first, low-waste, and climate-responsible conference in Delft. As engineers, scientists, and practitioners in particulate systems, we want to minimise the footprint of the event-and lead by example.
What we are committing to
What we include in the event footprint
To calculate a realistic footprint per participant, we account for the most meaningful sources of emissions:
Offsetting: simple, transparent, and tied to your travel
During registration you can select an offset option aligned with your expected travel type. The amounts below are indicative and include an allowance for the broader event footprint (venue energy, catering, and materials).
| Travel type | CO₂ (approx.) | Offset cost (incl. event footprint) |
|---|---|---|
| Short distance (train / car) | ~0.1 tonne | € 7.50 |
| European flight | ~0.3 tonne | € 22.50 |
| Intercontinental flight | ~0.6 tonne | € 42.00 |
Our partner: Trees for All
We collaborate with Trees for All, a Dutch foundation that plants and protects forests worldwide based on the principle: "the right tree in the right place."
Low-waste conference operations
Together for impact
By travelling rail-first where possible and offsetting your share during registration, you help make CHoPS 2027 a climate-responsible event. Let's grow forests-one conference at a time.
