CalibroAttendee Travel
Road, rail and air travel by attendees, speakers, event staff and production crews.
Plan, Measure and DeliverHigh Engagementnet-zero events.
Calculate emissions across attendee travel, venue energy, accommodation, catering, logistics, materials and waste. Plan reductions, offset residual emissions and maintain a complete carbon record for every event.
Sustainable Events Summit
In progressConvention Centre, Bengaluru, India
Estimated emissions
53.4 tCO₂e
Measure
Calculate emissions from event operations, suppliers and participant activity.
Reduce
Identify material emission sources and record planned reduction actions.
Offset
Select eligible carbon projects for residual event emissions.
Report
Generate the event carbon report and retain offset and retirement evidence.
Platform
One event record, from setup to public reporting.
Work through concrete modules without separating the calculator, participant records and offset evidence from the final report.
Event Setup
Record dates, venue, format, attendance, calculation boundaries and the emission categories that apply.
Carbon Calculator
Use category-specific inputs for travel, venue energy, accommodation, catering, logistics, materials, waste and digital participation.
Reduction Planning
Record reduction actions against the footprint, assign their status and keep the evidence connected to the event.
Attendee Participation
Invite attendees to submit travel activity and reconcile those records with the organizer’s event footprint.
Project Selection
Review eligible carbon projects and connect a selected portfolio to the event’s residual footprint.
Offset Management
Maintain offset quotes, transactions, event allocations and retirement evidence in the same workflow.
Event Reporting
Bring boundaries, assumptions, calculations, reductions, project allocations, transactions and retirement records into one report.
Public Event Page
Create a public-facing view of the event footprint, selected projects and documented completion status.
Emission categories
Measure the sources that make an event operational.
Select the categories in scope, record exclusions and replace estimates with activity data as it becomes available.
Review Calculation MethodologyVenue Energy
Electricity, backup generation, heating and cooling used across the event venue.
Accommodation
Hotel stays and room nights associated with attendee, speaker and staff travel plans.
Catering
Meals, beverages, service formats and food choices provided across the event program.
Freight and Logistics
Equipment, materials and supplier freight transported to and from event venue sites.
Materials and Production
Printing, staging, signage, merchandise and temporary installations used by the event.
Waste
Food waste, recyclables, landfill and other disposal streams generated by the event.
Digital Participation
Streaming, virtual attendance and digital infrastructure supporting remote participation.
Operational context
Built for real events.
Use an event-specific workflow for conferences, exhibitions, forums, ceremonies and hybrid programs.
