Why production teams sit at the centre of credible event carbon data

Comments Off on Why production teams sit at the centre of credible event carbon data

For production teams, sustainability has always been part of delivery. Power, logistics, materials and build decisions shape how events function in the real world, long before any reporting happens.

Carbon measurement, however, has often been pulled together after the event, sometimes using assumptions that don’t fully reflect what actually took place on site. That gap is closing.

As expectations around carbon data increase, production activity is becoming central to whether event reporting is credible or not. This is because the decisions made during production determine the quality of the event data everyone else relies on.

Production data already exists

Across the event lifecycle, production is one of the few areas where tangible, observable activity data already exists as part of day-to-day working.

Fuel use, power supply, transport distances, equipment loads, materials installed and removed are all elements production teams plan and manage as standard. They are also inputs required for credible carbon measurement

This is why activity-based approaches to carbon measurement consistently outperform cost-based estimates, particularly in production contexts. Spend rarely maps cleanly to emissions. Activity almost always does.

When production data is captured at source, sustainability teams are no longer forced to rely on proxies. Instead, they can work with information that reflects what actually happened and why.

What production-led data is already showing

When production activity is measured with enough detail, clearer emissions patterns start to emerge.

Power, technical infrastructure, freight and materials regularly account for a significant share of an event’s footprint. Just as importantly, these are areas where data confidence can be higher, because the information already exists.

This creates a clear opportunity. Production is one of the most practical places to improve the reliability of event carbon data.

How expectations are shifting for production partners

Production teams are increasingly being asked to explain what they delivered and how they delivered it.

Questions about power sources, fuel use, generator run-time, grid connections and transport decisions are becoming more common. These conversations reflect a wider shift across the industry: production decisions now sit directly upstream of carbon reporting.

This shift is already visible among specialist production partners, particularly those supplying power and technical infrastructure, where clients are looking for clearer explanations of the carbon implications of different delivery choices.

For production teams, this is less about taking on a reporting role and more about making existing decisions visible.

From delivery choices to useful insight

One of the most common weaknesses in event reporting is that production activity is captured at too high a level.

When detail is missing, sustainability teams fall back on averages. When detail is available, production data becomes one of the most informative parts of the footprint.

Factory42’s, The Green Planet project puts this into practice. By capturing specific information on production power, materials and technical delivery, the project moved beyond broad assumptions and towards a clearer understanding of where emissions actually sit. 

The value was the ability to explain why that figure looked the way it did and what could realistically be done differently next time.

That distinction is what turns measurement into insight.

Why better production data benefits the whole supply chain

Clear, consistent production data supports sustainability reporting and improves decision making across the event supply chain.

It helps organisers understand trade-offs between cost, logistics and impact. It supports venues in aligning infrastructure with real usage patterns. And it allows suppliers to demonstrate preparedness as expectations increase.

It also reduces risk. As environmental claims and procurement requirements become more rigorous, vague or heavily estimated production data becomes harder to stand behind.

Activity-based production data allows teams to say:

  • This is what we used
  • This is how it was powered
  • This is what we know and where the limits are

That clarity builds trust between teams who depend on each other’s information.

What production teams are and aren’t being asked to do

It’s worth being clear about what this shift does not mean.

Production teams are not being asked to own sustainability strategy, produce corporate emissions reports, or guarantee perfect data.

What is changing is the expectation that production activity can be recorded, understood and explained.

In practice, that often looks like:

  • Capturing fuel and energy use where possible
  • Recording transport distances and loads
  • Documenting material choices and reuse
  • Sharing data early, rather than retrospectively

Production as part of event readiness

As carbon data becomes part of how events are evaluated, production teams play a quiet but critical role in organisational readiness.

The projects and suppliers that stand out are the ones that can explain their decisions clearly, acknowledge limits honestly, and improve consistency over time.

For an industry built on precision and execution, this shift is an extension of the professionalism production teams already bring to event delivery.

For teams that want to explore this further, isla’s Event Carbon Measurement Starter Pack and TRACE case studies provide practical guidance and real-world examples.

The real data challenges sustainability leads in businesses that run events are facing

Comments Off on The real data challenges sustainability leads in businesses that run events are facing

Sustainability leads in businesses that run events are being held to higher scrutiny than ever before when it comes to their organisation’s emissions data. They’re expected to know what the numbers are and how confident the organisation is in them.

It’s part of the territory that events are internally and publicly scrutinised, which is why it’s extra important within this industry that an organisation’s sustainability data is as strong as possible.

For sustainability leads in businesses that run events who are finding this mission challenging, it is not a failure of intent or capability, but a reflection of the structural reality of how events are delivered and where current measurement practices still fall short.

As scrutiny increases, it’s important that we’re honest about where event data typically breaks down, and what credible progress really looks like in practice.

Events sit where data confidence is lowest

Insights from the Temperature Check Reports show a clear pattern: the areas with the highest emissions are often not the areas with the strongest data confidence.

Across industry datasets captured through TRACE:

  • Staff travel and accommodation data was completed in around 88% of measured events, making it one of the most consistently reported data areas.
  • Production transport data was recorded in approximately 75% of events, again with relatively low reliance on estimates.
  • In contrast, energy data was captured in only around 57% of events, and waste data even less consistently, despite both being known contributors to event emissions.

For sustainability leads, this creates a familiar challenge. An organisation may be measuring their events, but confidence varies sharply depending on the data type, particularly where primary data depends on venues or suppliers outside direct control.

Measurement effort does not equal measurement quality

Another key insight from industry data is that more measurement does not automatically mean better measurement.

Many organisations are already investing time in capturing event emissions, yet analysis shows:

  • Some of the most frequently reported emissions rely heavily on estimated data
  • Data is often captured inconsistently across events, even within the same organisation
  • Different teams apply different assumptions, limiting comparability over time

Audience travel is a good example. While often discussed as a priority, early industry reporting indicates only around 43% of events recorded any audience travel data at all, and the low rate of audience travel data capture is still accurate as of 2025. Where it was captured, it frequently represented only a proportion of total journeys.

For sustainability leads, partial data can still be valuable, but only when its limitations are clearly understood and communicated.

What leading organisations are doing differently

Organisational insights highlighted in the Temperature Check Reports point to a noticeable shift among more mature organisations.

These organisations tend to:

  • Prioritise data confidence over data completeness
    Focusing first on areas where reliable activity data already exists.
  • Embed measurement into event delivery processes
    Making data capture part of standard workflows, not a post-event clean-up exercise.
  • Standardise methods internally
    Applying consistent boundaries and assumptions across all events, even where gaps remain.

This approach reduces rework, improves internal trust in the data, and makes it easier for sustainability leads to explain results, including uncertainty, with confidence.

Learning from where the gaps are

One of the most valuable outcomes of industry measurement has been visibility of where data is missing or unreliable.

For example:

  • Waste volumes are often underreported, suggesting systemic reporting gaps rather than genuinely low waste generation.
  • Energy data is frequently estimated, highlighting ongoing challenges in accessing venue-level consumption figures.
  • Materials data, despite being heavily influenced by event design decisions, is inconsistently captured across event types.

For sustainability leads these gaps are signals, pointing to where internal processes, supplier engagement, or contractual data requirements need to evolve.

Reframing success for sustainability leads

As regulatory, assurance and stakeholder expectations grow, success is not defined by having a complete dataset.

It is increasingly defined by being able to say, with confidence:

  • Which data is robust
  • Where estimates have been used
  • How consistently methods are applied
  • And what is being done to improve quality over time

Industry reporting consistently shows that clarity builds trust, even when the picture is incomplete. Overstated certainty, by contrast, often creates more risk than transparency ever does.

Building progress without overclaiming

With time and due process, event data can become more consistent, more explainable and more useful.

For sustainability leads, progress often looks like:

  • Fewer assumptions year on year
  • Stronger internal alignment on boundaries
  • Improved data quality in priority areas
  • And a shared understanding of what ‘good enough for now’ actually means, at both an organisational and industry level

That is how event measurement matures, through repeatable, defensible practice.

For teams looking to strengthen how they approach event carbon measurement, the Event Carbon Measurement Starter Pack offers practical guidance on improving data quality, consistency and confidence.

Emissions data is your P&L: Without it, you’re flying blind

Comments Off on Emissions data is your P&L: Without it, you’re flying blind

By Anna Abdelnoor, CEO & Founder, isla & TRACE by isla

Imagine an accountant telling you it’s fine to just reconcile the books each month and there’s no need to actually look at the P&L 😳

The numbers balance, so what more do you need?

No analysis of margins, cost, cash… and no view of future exposure.

🙅🏻‍♀️ You’d fire them 🙅🏻‍♀️

Now imagine that same accountant saying they can help you, but only by comparing your accounts to other companies they work with.

Not how you performed last quarter, not whether you’re improving or getting worse, not what’s changing over time inside your business.

Just a benchmark that tells you how you stack up against someone else.

🙅🏻‍♀️ You’d fire them twice 🙅🏻‍♀️

If you’ve got a sustainability provider telling you that they offer more value than “just” emissions reporting because they offer you benchmarks about how you’re performing against others, or that they can help you demonstrate your sustainability creds – they’re completely missing the point.

It would be like that same accountant telling you how you’re performing without actually reconciling your books 🤭🙃

Consistent, comparable emissions data is as foundational to business continuity planning as your financial accounts.

Without either, you cannot forecast, mitigate, adapt, diversify, invest, reorganise or thrive.

No-one in their right mind would try to run a business without understanding trends in their revenue, costs, liabilities and cashflow, and emissions data feeds the insights around that information.

👉 It exposes where your supply chain is fragile
👉 It reveals where cost, carbon and risk concentrate
👉 It tells you where to put time, energy and money
👉 and just as importantly, WHERE YOU DO NOT NEED TO.

Comparing your performance – emissions or financial – to another business doesn’t help you understand what you’re already doing well, and it doesn’t gives you a baseline to forecast what you need to do differently as the operating environment shifts.

And the operating environment ✨is✨ shifting.

Geoeconomic shocks, geopolitical instability, regulatory change and resource constraints are already shaping margins, operations and impacting business continuity.

And it’s showing up in your accounts already – it’s just misattributed to rising costs, when the root cause of rising costs is ecological debt.

Benchmarks don’t help you plan for and solve the problems coming down the track in your near-term business future, without solid emissions reporting underneath them.

If you can get your head around that and learn how emissions data feeds business continuity, then your CFO and clients will thank you for it when they realise you’re bringing them decision-grade information instead of another sustainability narrative.

If what you want is to say you’re “doing good”, we’re probably not the product for you.

But if you’re an events business that wants to understand how to ensure continuity through sustained volatility, TRACE by isla helps with that.

2026 Event Sustainability Checklist

Comments Off on 2026 Event Sustainability Checklist

For busy event professionals ready to take sustainability seriously.

Sustainability now appears in most event RFPs. Current industry insight suggests that around 62% of RFPs include sustainability requirements, yet those requirements are often vague.

Questions like:

  • Do you have a sustainability policy?
  • Are you accredited?
  • Do you meet our sustainability standards?

are increasingly common. But they don’t always translate into what event teams actually need in order to deliver an event, measure its impact, or meet client and stakeholder expectations.

Whilst an event supplier may be strong on sustainability at a company level, that doesn’t automatically mean

  • You’ll have actionable emissions data for your event
  • Measurement will align with reporting needs
  • Information will be consistent and comparable across events or suppliers
  • You’ll generate insights that support real design and procurement decisions

For event professionals, this creates a practical problem. Asking about sustainability capability is not the same as requesting the specific data and support your event requires.

This checklist is designed for teams who need to move from sustainability intent to consistent delivery and credible data, without adding unnecessary complexity to already busy workflows.

Breaking down carbon emissions benchmarks by event type and size

Comments Off on Breaking down carbon emissions benchmarks by event type and size

The 2025 Temperature Check Europe report provides a data-led overview of carbon emissions across the European events sector, using one of the largest aggregated datasets available for business events. By analysing high-quality TRACE data from approximately 1000 events across multiple countries, it establishes a clearer picture of how emissions are distributed across event activities and formats. 

The report highlights the sector’s main carbon hotspots, ongoing improvements in measurement practice, and the need for reliable baselines to guide effective reduction strategies. These baselines set the groundwork for going deeper – breaking emissions down by event type and event size – so organisations can understand how their events compare with the wider landscape and make informed, confident decisions.


How different event types influence carbon emissions

Event formats vary widely in their carbon profiles. High-production environments such as exhibitions or experiential builds tend to sit at the upper end of the carbon scale. Meetings, activations and dinners typically fall much lower. Understanding this variation helps planners benchmark their event’s carbon footprint accurately and identify where changes will have the greatest impact.

Using TRACE data, we’ve visualised median emissions (kgCO₂e) by event type as relative-sized bubbles, a clear way to see how categories compare at a glance.

Benchmark emissions by event type

These visuals give teams practical benchmarking context by showing:

  • Typical emission ranges for common event types
  • How materials, production, and travel influence different formats
  • Where an event sits relative to industry norms
  • Which levers are most likely to deliver reductions

For those who need deeper detail, including quartiles and the amount of variability, the full event-type benchmarks are available to download here.


Why event size changes the picture

Event size is another major factor shaping event carbon emissions. Larger events do generate more total emissions, but the relationship with emissions intensity is different. When measured as kgCO₂e per attendee, many larger events show greater efficiency compared to smaller ones. This reflects the value of consolidated logistics, more efficient venue energy use, and economies of scale in production.

Benchmark emissions by event size

Event size influences:

  • Travel demand and distance
  • Catering volume and menu choices
  • Venue energy usage
  • Material and build requirements

Even within the same type of event, emissions profiles shift significantly as the audience grows. This is why size-based benchmarks matter: they help teams understand both the absolute footprint of an event and its per-attendee emissions intensity.

Actions that consistently support lower emissions at any scale include:

  • Designing production to reduce material use and increase reuse
  • Optimising energy loads and collaborating with venues
  • Managing food waste and selecting lower-impact menus
  • Encouraging lower-carbon travel behaviour
  • Embedding measurement early at the planning stage to inform decisions, supporting improved data quality and comparability post event

The full size-based benchmark tables are also available to download here.


Why event carbon benchmarking matters

Good benchmarking gives teams a credible frame of reference to assess their performance and identify where meaningful reductions can be achieved.

By combining baselines from the 2025 Temperature Check Europe report dataset with deeper breakdowns by type and size, organisations gain a much clearer view of:

  • What ‘typical’ looks like for their kind of event
  • Where their own footprint sits in relation to the wider industry
  • Which categories and behaviours drive emissions
  • Where to prioritise effort to make progress

When measurement is consistent and grounded in activity-based data, the result is simple: more confident decisions and more effective climate action.

A note on using these benchmarks responsibly

These benchmarks are a helpful guide, but they’re only as strong as the data behind them. While the dataset is one of the most comprehensive available, measurement across the sector is still uneven, with gaps in boundaries, activity data and reporting consistency. This means benchmarks should be seen as a reference point, not a replacement for your own measurement. 

The most meaningful comparison will always come from tracking your events over time. Building your own dataset is what enables true progress, giving you clarity on where emissions are coming from and where reductions will have the greatest impact for your events. The sooner measurement becomes part of your regular workflow, the sooner your benchmarks become more accurate and actionable and the sooner you can be celebrating your progress.

Event badges: how to reduce single-use waste.

Comments Off on Event badges: how to reduce single-use waste.

According to our own research 2.14kg of waste is pridcued per attendee per event, this is just under the amount generated by the average UK household per day. The source of this waste likely comes from a variety of sources, including catering, production and often small print items. Even when there is separate recycling on-site, the onward life of these items is in the hands of delegates and thus even though there is recycling on-site it’s up to the delegate’s own conscience if they use it and some items may inadvertently be taken home and end up in general waste.

Therefore coming up with alternative solutions to the waste generated from items where you have less oversight or control of onward life is an important step in the reduction of waste from single-use items such as name badges, maps, leaflets and programmes. 

Looking specifically at name badges, there are a variety of approaches to lessen the impact of waste here. 

BEST:

Utilise an in-event app to share important information with delegates This has the benefit of being editable for any last-minute programme changes and can also be used for networking. Or for a more traditional lanyard-style name badge, consider using a solution such as Blendology for paperless networking. 

In May 2023 at isla’s flagship event transform at Kew Gardens we saved 1.86kg* of paper by using Blendology OneTap badges instead of printed name badges for 124 delegates. 

“It was great to see the way the Blendology badges encouraged networking and interaction. I loved ‘bumping badges’ with current and new connections and the fact that contact information was transferred automatically, no need for the clunkiness of pen and paper or exchanging not-so-planet friendly paper business cards. A follow-up email from Blendology also made it really easy to access your contacts list post-event. Innovations like Blendology are a sign of the really exciting things to come in the events industry of tomorrow,” Miriam Habtesellasie, MarComms Lead, isla

BETTER:

Consider the material that the name badges are made from and replace the single-use plastic pouch with a durable, recyclable paper option that will still last for multi-day events. This is particularly important considering the upcoming introduction of the single-use plastics ban in England this October. Are there also other ways or creative solutions to the single-use nature of name badges? Perhaps chalkboard badges or wipe clean ensuring that they are reused across different events. 

Also, consider the material of the lanyard. Can you source bamboo or recycled PET for example in order to move away from non-biodegradable materials, such as nylon, with higher environmental impact?

BASIC:

If you’re unable to make physical changes to your name badges, can you consider how to make sure that their onward life is what you intended? Badge recycling points at all of the exits to events can help give you this control and be a prompt to delegates to drop them off before leaving and you to ensure that they are properly separated and recycled, perhaps investing in staff to ensure that delegates hand over their badges before leaving. You may also want to consider designing lanyards or plastic pouches without sponsorship details or event dates so that they can be reused time and again, or at least until an event rebrands. 

How will your delegates network at your next event?

This or That: Bag or Bottled Wine

Comments Off on This or That: Bag or Bottled Wine

Moving away from the traditional wine bottle to a more sustainable alternative.

Wine should come in a glass bottle, right? Actually, wrong if wine drinkers want to do their bit for the planet’s resources and environment.” Jancis Robertson (OBE, ComMA, MW)

Drinking and serving wine is a practice steeped in tradition, from treading the grapes barefoot to popping the cork. As such, the quality of the wine and the drinking experience is heavily rooted in the perception of the bottle. The labels having an art movement of their own, in both the natural wine world filled with artists and designers. Or wine from more traditional winemakers where so much history and culture are held in the bottle and it’s the label. 

It’s natural that when the wine comes without any of those aspects of ceremony and art, a stigma is attached to it. The idea that it’s an inferior product. We can see this clearly in the perception of wine with a screw-top. Where we jump to the conclusion that the liquid inside isn’t as high quality or made with the same environmental and sustainability considerations.

The wine bottle is the biggest environmental impact area of the wine industry. Generating large amounts of glass to be recycled and adding shipping weight to the transportation of the wine. Moving away from the glass bottle then has the potential to contribute to both financial savings and reductions to the carbon footprint of a glass of wine.

“Current estimates put the transportation of glass packaging at anywhere between 80% and 90% of the emissions costs of the wine industry”

What are the alternatives?

There are many alternatives to the glass bottle, including cans, bag in box or keg. And a growing body of importers who are innovating alongside winemakers to bring these to market. Who are utilising and exploring more sustainable methods of serving and celebrating their wine. Meaning that the bag-in-box wine, or maybe you know it as goon wine, is no longer reserved for house parties and festivals. It can be utilised to reduce waste and emissions associated with the drinks industry.

I spoke to Roman at Modal Wines who are importers of wine from independent winemakers with a genuine passion for their craft, regardless of location or style. Modal Wine showcase wine that is always made with the highest respect for nature; from the vineyards to the cellars. They were recently at the Vessel wine fair in London, where wine in alternative packaging was in the spotlight. We caught up about some of the benefits of, and response to, diversifying their portfolio into alternative packaging.

Why are you moving away from the traditional wine bottle? 

We have felt for a long time that wine that is consumed in the year or so following its release does not need to come in glass packaging.  Current estimates put the transportation of glass packaging at anywhere between 80% and 90% of the emissions costs of the wine industry. So it’s very clear that this is the area where we as an industry have the most room for improvement in terms of our environmental impact.  We are finally reaching a point where consumers are shifting their views on packaging, and putting a higher value on environmental concerns, so the timing feels right to make a change. 

Is there a price difference between the wines?

The actual liquid costs the same whether it goes in glass, box, can, or keg – it’s the same wine after all.  Packaging costs vary, with some alternatives being less expensive and some working out around the same once all is said and done, but the main reason a consumer sees a price difference is because of lower shipping costs.  Since more wine can fit in less space and add less weight to a shipping load in alternative packaging, you can get a higher quality wine at a lower price.  It’s one of the few instances where lowering environmental costs actually lowers the price you pay!  

How popular are your bag in box/alternatives? 

We started with Bag in Box wines from our producer Valdibella a couple of years ago, and were frankly overwhelmed with the response.  This made it clear to us that people were ready for higher quality wines in alternative formats, and set us on the road to grow the range and seek out other packaging alternatives.  We have recently launched Pet Nat in cans (which actually finish their fermentation in can!) from Celler Entre Vinyes, and they have been off to a great start as well.  We are just starting to receive our first wines in keykeg.  As these are tried-and-true favourites from our range we are excited to see how they fare in their new format. 

Ultimately, we are lucky to work with growers that produce delicious wines and customers who are open-minded to trying alternative formats, so we are optimistic that this is just the beginning of the journey. 

How will you be serving wine at your next event?

A Case Study: Green Space: Dark Skies Shining the Spotlight on Outdoor Event Sustainability

Comments Off on A Case Study: Green Space: Dark Skies Shining the Spotlight on Outdoor Event Sustainability

Leading outdoor arts organisations Walk the Plank, were at the helm of Green Space, Dark Skies, one of ten projects commissioned as part of UNBOXED: Creativity in the UK a ground-breaking UK-wide celebration of creativity in 2022, designed to celebrate science, technology, engineering, the arts and maths.

Walk the Plank had four core sustainability targets for the event – which saw thousands of people, from all paths in life, to experience beautiful landscapes across the UK at dusk, between April and September 2022 – which were as follows:

  • 100% renewable energy usage
  • Zero-waste policy on resource usage
  • Limit disposable and single-use plastics
  • Follow the waste hierarchy

In the informative video below, Rebecca Whitman, a freelance consultant and the event’s Sustainability Manager tells TRACE Customer Success Manager Kate Kieran, how the organisation utilised TRACE to help meet the above and also put them on the path to win the Best Sustainability award at the National Outdoor Events Association in the same year.
