At PromCon, organizers announced a commitment to making the event not just carbon neutral but 100% carbon negative, thanks to Grafana Labs' donation. Instead of traditional conference swag like T-shirts, Grafana Labs purchased carbon credits from Cool Effect to offset 465 tons of carbon dioxide, covering 200% of the estimated travel and food emissions for all attendees. The funds from these carbon credits will support the protection of Brazil's Jacunda Forest Reserve. Attendees received carbon-offset acknowledgment cards printed on plantable basil-seed paper, reflecting a shift towards more sustainable conference practices. Grafana Labs intends to implement similar environmental initiatives at future conferences.
