Corporate Event Emissions: Should They Be Included In Business Carbon Reporting?

For businesses that regularly organise events, understanding where those events fit into wider carbon reporting isn't always straightforward.
You may already be measuring business emissions from areas such as energy use, business travel, company vehicles and purchased goods. But when your organisation runs a conference, exhibition, awards ceremony or company event, a whole new range of activities can generate emissions too.
There may be attendees travelling from across the country, hotel stays, venue energy use, catering, production, freight and suppliers to consider.
So, what happens to all of that carbon data?
In many cases, corporate event emissions can form part of a company's wider greenhouse gas inventory, depending on the activity, your organisational and reporting boundaries, and the emissions sources involved.
Understanding that relationship can help businesses avoid treating events as an entirely separate sustainability exercise and build a more complete picture of their environmental impact.
In this guide, we'll look at how corporate events can fit into business carbon reporting, which emissions you may need to consider and why collecting event data can be valuable even when reporting requirements differ between organisations.
What Are Corporate Event Emissions?
Corporate event emissions are the greenhouse gas emissions associated with planning, delivering and attending events organised as part of business activity.
Depending on the event, these emissions could come from:
Venue energy use
Attendee travel
Employee and crew travel
Hotel accommodation
Catering
Event production and materials
Freight and logistics
Waste
Purchased goods and services
External suppliers
A small internal meeting will naturally have a very different carbon footprint from a multi-day international conference, so there isn't one standard footprint that applies to every corporate event.
The first step is understanding which activities are relevant to your event and collecting enough information to measure them consistently.
This creates the foundations for an individual corporate event carbon footprint, but it can also provide useful data for understanding the organisation's wider emissions.
Do Corporate Event Emissions Count Towards A Company's Carbon Footprint?
They can. An organisation's greenhouse gas inventory is built according to defined organisational and operational boundaries.
Rather than deciding that an event either "counts" or "doesn't count" as a single item, businesses need to look at the individual activities associated with that event and determine how they fit within the reporting framework being used.
Under the GHG Protocol Corporate Standard, emissions are categorised into Scope 1, Scope 2 and Scope 3 depending on where they occur and the organisation's relationship to the emissions source.
That means the emissions associated with an event can potentially appear across different scopes rather than belonging to a single "event emissions" category.
For example, fuel used by a company-owned vehicle to transport equipment could be treated differently from emissions associated with an attendee taking a flight to reach the same event.
This is why understanding the activities behind the event is more useful than simply treating the event itself as one carbon figure.
Where Can Event Emissions Sit Across Scope 1, 2 And 3?
Corporate event emissions can potentially span Scope 1, Scope 2 and Scope 3, depending on how the event is delivered and which assets or services the organisation owns, controls or purchases.
Scope 1 covers direct emissions from sources owned or controlled by the reporting organisation. For an event, this could include relevant fuel use from company-owned vehicles or equipment where those sources fall within the organisation's reporting boundary.
Scope 2 covers indirect emissions associated with purchased electricity, steam, heating and cooling consumed by the reporting organisation. Whether venue energy falls within an organisation's Scope 2 inventory depends on the circumstances and reporting boundary rather than simply because the energy was used during an event.
Scope 3 covers other indirect emissions throughout the value chain. This is where many common event activities may become relevant, including purchased goods and services, business travel, transportation, waste and other value-chain activities.
Our guide to What Are Scope 1, 2 and 3 Carbon Emissions explores the three categories in more detail and how they can apply across both businesses and events.
For event teams, the important point is that there isn't a separate fourth scope for events. The individual emissions sources need to be understood within the same wider framework used for organisational carbon accounting.
Are All Event Emissions Automatically Included In Business Carbon Reporting?
Measuring an event carbon footprint and determining what should appear within a particular corporate disclosure are related, but they aren't necessarily the same exercise.
What a company reports will depend on factors including the reporting framework being followed, its organisational and operational boundaries, applicable regulation and the data being disclosed.
This distinction is particularly important when businesses start measuring areas such as attendee travel.
Attendee journeys can represent a significant part of an individual event's footprint, making them extremely useful to measure when the goal is understanding and reducing the environmental impact of the event.
However, that doesn't mean every attendee journey automatically belongs within every organisation's mandatory corporate disclosure.
The same principle applies across other event activities.
Rather than assuming that every number from an event footprint should simply be added to a company total, teams should establish what they are measuring, why they are measuring it and how each emissions source fits within their chosen reporting methodology.
Why Is Scope 3 Particularly Relevant To Corporate Events?
For many events, a large proportion of the activities organisers want to understand happen outside their direct control.
The venue may be operated by another organisation. Guests choose how they travel. Catering comes from external suppliers. Production materials may pass through several businesses before arriving onsite.
This makes Scope 3 particularly relevant when discussing event emissions, and it can also make collecting accurate information more challenging.
An event organiser might need information from attendees about their journeys, from hotels about accommodation, from suppliers about materials and logistics, or from venues about energy consumption.
Our attendee travel resources explore this challenge in more detail. For example, tracking attendee travel can involve gathering information about journey origin, transport method and other travel data, while reduction decisions can then use those insights to improve future event planning.
When event carbon data is collected consistently, it can become useful beyond the footprint of a single event.
Why Include Event Emissions In Your Wider Carbon Data?
Even where every measured event emission isn't required within a particular disclosure, understanding corporate event emissions can still provide businesses with valuable information.
Events can involve substantial activity over a relatively short period, and looking at them separately from everyday operations may make it harder to understand where environmental impact is occurring across the organisation.
Bringing relevant event data into the wider carbon management process can help teams:
Identify emissions hotspots associated with events
Understand how event activity contributes to wider organisational emissions
Compare the impact of different events
Improve the consistency of carbon data collection
Make more informed venue, travel and supplier decisions
Track whether changes are reducing emissions over time
Give sustainability teams better visibility over event activity
It can also help connect event planning with the sustainability work happening elsewhere in the business.
If an organisation is already working with suppliers, reviewing travel policies or reducing waste across its normal operations, the information collected from events may reveal opportunities to apply similar thinking there too.
What Event Carbon Data Should Businesses Collect?
There isn't one universal list that every business needs to collect for every event.
Instead, start by understanding the main activities associated with the event and where meaningful emissions are likely to occur.
Useful information might include:
Travel data
Where attendees, employees and crew travelled from, how they travelled and, where appropriate, journey distances.
Venue information
Relevant energy consumption and information about the venue's operations where this data is available and appropriate to the footprint being calculated.
Accommodation
Hotel stays associated with attendees, employees or other relevant event participants.
Catering
Information about food and drink provided during the event, including quantities and types of catering where appropriate.
Production and purchased goods
Materials, equipment, signage, staging and other products or services purchased to deliver the event.
Freight and logistics
Transport associated with equipment, materials and other event requirements.
Waste
The quantity and type of waste generated and, where available, how it was treated.
Supplier information
Relevant activity data provided by external suppliers involved in delivering the event.
The aim isn't to collect data for the sake of having more data. It is to build enough visibility to understand meaningful emissions sources and make the information useful for measurement, reporting and future reduction decisions.
How Can Businesses Avoid Double Counting Event Emissions?
This is an important consideration when event and organisational carbon data start being brought together.
If an emissions source has already been included within a company's greenhouse gas inventory, adding the complete event footprint on top without checking what it contains could duplicate some of that activity.
For example, employee business travel associated with an event may already have been captured through the organisation's normal travel data.
Instead of treating an event footprint as one additional number to add to a corporate total, businesses should work at the level of the underlying emissions sources.
Clear reporting boundaries, consistent categorisation and good carbon data management make it easier to understand what has already been captured and where additional event information belongs.
This is also where using one connected approach to business and event carbon tracking can be useful.
When teams have greater visibility across both areas, it becomes easier to understand how individual events relate to wider organisational activity rather than managing two completely disconnected sets of figures.
How Can Event And Sustainability Teams Work Together?
Corporate event emissions often sit between different teams.
An event team may have the best access to information about venues, attendees, production and suppliers, while a sustainability team may understand the organisation's reporting boundaries, methodology and wider greenhouse gas inventory.
Bringing those teams together early can make the process much easier.
Before an event, teams can agree which information needs to be collected and who is responsible for obtaining it. During and after the event, that data can then be recorded consistently and reviewed in the context of the organisation's wider carbon reporting.
This is generally more useful than asking an event team to reconstruct several months of travel, supplier and venue information long after the event has finished.
It also means carbon measurement can begin influencing event decisions rather than simply documenting them afterwards.
Corporate Event Emissions And Business Carbon Reporting With Scope
At Scope, we've built our platform around the idea that business and event carbon data shouldn't have to exist in completely separate places.
Businesses can measure emissions associated with their wider operations while event teams can collect and understand data relating to individual events.
That gives organisations the flexibility to look closely at a corporate event carbon footprint while maintaining visibility over their wider business emissions.
For companies running multiple events, this can also make it easier to build a consistent measurement process over time.
Instead of starting again after every conference, exhibition or company event, teams can use previous carbon data to understand recurring hotspots, compare events and make more informed decisions about future activity.
Start Building Event Emissions Into The Wider Picture
Corporate events can introduce a wide range of emissions sources, and understanding where they fit into business carbon reporting requires more than simply calculating one event footprint and adding it to an organisational total.
The individual activities need to be understood within the organisation's reporting boundaries and the carbon accounting framework being followed.
For businesses that regularly organise events, collecting this information can still be extremely valuable. It provides greater visibility over event activity, supports more informed reduction decisions and can help sustainability and event teams work from a more connected set of carbon data.
If you're beginning to explore your company event emissions, start by identifying the major activities associated with your events and how they relate to the emissions you're already measuring across the wider business.
Scope can help you track business and event emissions in one place, giving your teams a clearer view of carbon data across the organisation.
