Sample data
Built on the standards your auditors already use
- GHG Protocol
- Supports ISO 20121
- Scope 1, 2 and 3
- Emissions factors updated annually
Seven categories, built for how events actually run.
Generic carbon tools ask you to force an event into a corporate reporting shape. EventZero measures the categories an event produces, and maps them back to the standards afterwards.
Travel
Delegate and crew travel by air, rail and road, calculated from distance and mode.
Venue energy
Metered electricity and gas, or an estimate from floor area and hours.
Accommodation
Room nights by location, matched to national grid and hotel factors.
Food and beverage
Covers served by menu type, with catering supplier data where available.
Freight and logistics
Inbound and outbound movement of build, stock and equipment.
Production and build
Stand build, signage and set materials, including reuse rates.
Waste
Streams by weight and destination, from landfill to recovery.
One structured dataset
Every category resolves to the same audit-ready record, per event and across the portfolio.
Measurement that tells you what to change.
Every figure carries a mechanism and an outcome. Your team sees where the footprint concentrates, what a change is worth, and what evidence supports it.
Travel is 68% of this event's footprint. Shifting 20% of interstate delegates to rail would cut 14.2 tCO2e.
Sustainability Pressure Is Rising. Most Teams Aren't Ready.
Stakeholders, sponsors, and regulators increasingly expect measurable environmental data. Not estimates. Not pledges.
Establishing your baseline this year strengthens next year's strategy.
No Structured Baseline
Without measured data, sustainability claims are unverifiable, leaving you exposed to scrutiny from sponsors, clients, and regulators.
Manual, Error-Prone Processes
Spreadsheets and ad-hoc calculations produce inconsistent results that cannot withstand third-party review or audit.
Missed Reduction Opportunities
Without visibility into emissions by category, high-impact reduction levers stay hidden and budgets go to the wrong places.
Reporting Takes Too Long
Pulling data together for stakeholder reports can take weeks. By then, the moment to act has already passed.
Built for the teams accountable for the numbers
Four kinds of organization carry the reporting burden for events. Each needs the same structured data for a different reason.
Corporate teams
Data your board can rely on
Structured baselines across your event portfolio, aligned to Scope 1, 2 and 3, so ESG disclosure draws on measured data rather than estimates.
Event agencies
Sustainability you can put in a pitch
Client-ready reporting on every event you deliver, so sustainability becomes a service you offer rather than a request you deflect.
Associations
Numbers your sponsors and members ask for
Measured reporting on your flagship conference, with the evidence sponsors now request and the transparency your members expect.
Government and public sector
Documentation built for scrutiny
Transparent methodology and standards-aligned records, with the evidence trail attached to each figure.
