Shared Impact Attribution
When a venue hosts an event, who owns the emissions? The venue operator who runs the building, or the event organiser who fills it? Without proper attribution, both count the same energy twice. Or worse, neither counts it at all.
The problem
Double counting is the default
Under the GHG Protocol, a venue operator reports the building's energy consumption as their Scope 1 and Scope 2 emissions. That covers heating, cooling, base lighting, and everything that keeps the building running.
Now an event organiser rents that venue for a concert, a conference, or a match. They bring in extra lighting, stage power, catering, and 20,000 attendees. Under the same GHG Protocol, the event organiser reports the venue's energy as their Scope 3, Category 8: upstream leased assets.
The same kilowatt-hours now appear in two inventories. The venue owner counts them as Scope 2. The event organiser counts them as Scope 3. Both are technically correct, but the emissions are counted twice. When either party claims a reduction, it becomes impossible to verify who actually drove it.
Example 1 of many
Venue operator
Scope 1 and 2
Building energy, HVAC, base lighting, maintenance. These are direct emissions from running the venue day to day, whether or not an event is happening.
Scope 3, Category 13
Downstream leased assets. What tenants and event organisers do inside the building is the venue operator's Scope 3.
Example 2 of many
Event organiser
Scope 1 and 2
Generators, owned vehicles, their own office energy. Typically a small portion of total event emissions.
Scope 3, Category 8
Upstream leased assets. The venue's energy during their event. Plus attendee travel, catering, materials, and waste, which typically make up 70 to 90% of total event emissions.
The overlap
The venue's energy during the event appears in the operator's Scope 2 and the organiser's Scope 3. Both report it. Neither knows how much belongs to whom. These are just two examples. The same overlap occurs with sponsors, suppliers, caterers, transport providers, and any party that shares operational control.
Why it's complicated
A venue hosts hundreds of events per year
A conference centre might host 200 events in a year, each with different organisers, different setups, different energy demands. A stadium has matchdays, concerts, corporate events, and community days. Each event has a different footprint, and each organiser needs their own accurate share of the building's emissions.

How 50X Impact solves it
The “Digital Twin” knows who owns what
The “Digital Twin” models the entire venue: every zone, every energy meter, every activity. When an event takes place, the platform knows which energy was base building (venue operator's Scope 1/2) and which was event-specific (the organiser's share).
Base building energy, the HVAC that runs 24/7, the lighting in corridors, the office spaces, stays with the venue operator. Event-specific consumption, the stage power, the extra cooling for a packed arena, the catering kitchens, is attributed to the event organiser.
Shared infrastructure like parking, security lighting, and waste handling is split proportionally based on actual usage data, not estimates. Every split is documented, traceable, and auditable.
Model the venue
The “Digital Twin” maps every zone, meter, and activity. Base building operations are separated from event-specific areas.
Capture each event
When an event is created, its energy use, waste, catering, and attendee data are linked to that specific event and its organiser.
Split shared infrastructure
Parking, corridors, waste systems. Usage is allocated proportionally based on metered data, headcount, or operational hours.
Report without double counting
The venue operator gets a clean Scope 1/2 inventory. The event organiser gets an accurate Scope 3 Category 8 figure. No overlap.
Attribute reductions
When the venue switches to renewable energy, that reduction is reflected in every event organiser's footprint. When an organiser reduces catering waste, that's attributed to them, not the venue.
Who benefits
Everyone reports accurately. Nobody counts twice.
Venue operators
A clean Scope 1/2 inventory that excludes tenant emissions. Scope 3 Category 13 is reported separately with full traceability. Auditors and regulators get a clear trail from every number back to its source.
Event organisers
An accurate Scope 3 figure for the venue they rented, properly split from the base building energy. No guessing, no overreporting, no underreporting. Numbers that regulators and leagues accept first time.
Sponsors and partners
Some sponsors want to take emissions onto their own ledger. Attribution makes that possible: a stage, an activation, or an event zone assigned to the partner willing to own them. Verified and visible on their own dashboard.
