Know Your Event's Carbon Footprint Before the Doors Open

Point A

Event organisers get sustainability questions from sponsors, venues, and attendees—but measuring emissions after the event means you can't offset in time. Spreadsheet calculations miss major categories.

Point B

NetNada estimates your event's carbon footprint during planning using industry benchmarks. Measure actuals post-event. Offset and certify. Issue sustainability reports sponsors actually want.

Concrete Benefits

No marketing fluff. Just measurable outcomes you can verify.

Pre-Event Emissions Estimate

Input expected attendance, venue location, and event type. Get baseline carbon estimate in minutes using benchmarks from 500+ events. Plan offsets before tickets go on sale.

Pre-event estimation in 15 minutes

Climate Active Events Aligned

Our methodology aligns with Climate Active's Carbon Neutral Events certification. If you want the government-backed logo, your data is already in the right format.

Attendee Travel Calculator

Travel is typically 70-85% of event emissions. Our tool estimates based on attendee postcodes/countries, transport mode splits, and distance calculations. Capture actual data via survey integration.

Travel: 70-85% of event emissions

Venue Energy Integration

Partner with major Australian venues (ICC Sydney, MCEC, Adelaide Convention Centre) for direct energy data feeds. No more chasing venue sustainability managers for utility bills.

Catering & Waste Calculations

Food and waste often overlooked. Our system calculates emissions from catering (menu type, food miles) and waste streams (landfill, recycling, composting). Based on actual event data, not generic averages.

Food + waste calculated

Carbon Neutral Certificate

Purchase verified offsets through NetNada marketplace. Issue branded carbon neutral certificate for your event—sponsors and attendees love sharing these.

Instant offset + certificate

How It Works

From planning estimate to certified carbon neutral event in 4 steps. Works for conferences, festivals, corporate events, and sporting matches.

1

Create Event Profile

Enter event details: type, expected attendance, dates, venue(s). System selects appropriate emission factors and benchmarks for your event category.

2

Estimate Pre-Event

Using industry benchmarks and your inputs (venue energy estimate, attendee origins, accommodation nights), generate preliminary carbon footprint. Use for sponsor pitches and sustainability messaging.

3

Collect Actual Data

Post-event, input actual figures: ticket sales by postcode, venue energy bills, catering quantities, waste weights. Optional: attendee travel survey for primary data.

4

Offset & Certify

Calculate final emissions, purchase offsets from verified projects, and generate carbon neutral certificate. If seeking Climate Active certification, we prepare the submission package.

Product Features That Do the Heavy Lifting

For multi-day festivals and conferences, Real-Time Carbon Tracking shows daily emissions accumulation—useful for making operational decisions during the event. Learn more →

Real-World Results

How companies in your industry use NetNada to solve specific problems.

Music Festival (45,000 attendees)

Challenge

Sponsor required carbon neutral certification. Festival had 3 months until event. No historical emissions data to work from.

Solution

Used NetNada pre-event estimation with similar festival benchmarks. Purchased offsets upfront (adjusted post-event). Collected actual travel data via app survey. Final emissions: 3,200 tCO2e. Carbon neutral certificate issued 2 weeks post-event.

Carbon neutral in first year

Annual Industry Conference (2,500 delegates)

Challenge

Attendees flying from interstate and overseas. Board wanted sustainability report for AGM but didn't know where to start measuring.

Solution

NetNada calculated travel emissions from registration data (origin postcodes). Venue provided energy data via partnership. Total: 890 tCO2e, with 78% from air travel. Report showed year-on-year comparison for ongoing improvement.

Published sustainability report at AGM

Corporate Product Launch Event

Challenge

Marketing team promised 'sustainable event' to media. Needed to back up claim with actual data. Event in 6 weeks.

Solution

Quick estimation showed 45 tCO2e (mainly travel and catering). Offset with Australian bushfire recovery credits. Issued carbon neutral certificate for press release. Actual measurement post-event confirmed estimate was accurate within 10%.

Credible sustainability claim for media

Sporting Event (NRL Match)

Challenge

Stadium wanted to understand per-game emissions to offer carbon neutral match-day packages to sponsors.

Solution

NetNada built match-day model: stadium energy, crowd travel (ticket holder postcodes), food/beverage, broadcast. Average match: 320 tCO2e. Premium sponsors now buy carbon neutral match packages ($8k includes offsets + marketing rights).

Frequently Asked Questions

Common questions about this solution

What emission sources should be included in event carbon footprint?
Comprehensive event measurement includes: attendee travel (usually largest), venue energy, accommodation, catering and beverages, waste disposal, staff/talent travel, freight and logistics, marketing materials, and digital/streaming. NetNada covers all categories with appropriate estimation methods.
How accurate are pre-event estimates?
Pre-event estimates using industry benchmarks are typically accurate within 20-30% of final measured emissions. Accuracy improves when you have registration data (for travel estimation) and venue energy estimates. We recommend budgeting offsets at +25% of estimate to ensure coverage.
Can I get Climate Active certification for my event?
Yes. Climate Active offers Carbon Neutral Events certification. Requirements: measure all material emission sources, implement reduction strategies, offset remaining emissions with eligible credits. NetNada generates Climate Active-compliant carbon accounts and manages the submission process.
How do I measure attendee travel emissions?
Two methods: 1) Use registration/ticket data (postcodes or countries) with transport mode assumptions based on distance—this is default. 2) Deploy attendee survey asking actual transport mode. Method 1 is sufficient for most certifications; Method 2 provides higher accuracy for repeat events tracking improvements.
What about virtual/hybrid events?
Virtual events have lower emissions but aren't zero. We calculate: attendee device energy, streaming infrastructure, speaker equipment. Hybrid events combine in-person calculation with virtual component. Virtual attendance typically adds 0.5-2 kg CO2e per attendee (vs 50-500 kg for in-person).
Which offset projects are appropriate for events?
For Australian events, we recommend Australian Carbon Credit Units (ACCUs)—especially bushfire recovery, Indigenous land management, or renewable energy projects. International events may prefer Gold Standard or Verified Carbon Standard projects. All offsets in our marketplace are pre-vetted for quality.
How do multi-venue events work?
For festivals or conferences using multiple venues, create venue profiles for each location. System calculates venue-specific energy and allows attendee flow between venues. Final report shows total emissions and per-venue breakdown for future venue selection decisions.
Can I compare our event year-over-year?
Yes, and you should. NetNada maintains historical event data with consistent methodology. Year-on-year comparison shows: total emissions trend, per-attendee intensity, reduction from interventions (e.g., switching to renewable energy venues, promoting public transport). Essential for demonstrating improvement.
