Event Sustainability Trends for 2027: 6 Changes Event Organisers Should Know
Event sustainability is becoming a more important part of how conferences, exhibitions, corporate events and live experiences are planned. For organisers, the challenge is no longer simply finding products described as sustainable. It's understanding which decisions could genuinely improve an event's environmental performance and how to measure the results.
Looking ahead to 2027, the event sustainability trends worth watching reflect this increasingly practical approach. From collecting carbon emissions data to rethinking temporary builds and working more closely with suppliers, organisers have opportunities to make more informed choices throughout the planning process.
These developments aren't necessarily new, but they're important areas for event teams to consider as they plan for the year ahead.
At Scope Carbon Tracking, we believe sustainability decisions should be supported by evidence wherever possible. It's easy to assume that a reusable material, alternative power source or local supplier will automatically be the better option, but the full picture can be more complicated.
If you're beginning to explore your event's environmental impact, our free Event Carbon Calculator can help you start measuring emissions associated with your event. You can begin with the information you have and build a more detailed picture as additional data becomes available.
We've brought together six sustainable event trends worth understanding, with practical advice on how event organisers can apply them.
What are the Biggest Event Sustainability Trends in 2027?
The six event sustainability trends we believe organisers should pay attention to in 2027 are carbon measurement, circular event production, smarter energy use, supplier collaboration, structured sustainability management and evidence-based environmental claims.
While these aren't entirely new concepts, they represent practical priorities for event teams looking to better understand and manage environmental impact in the year ahead.
Each addresses a different part of event planning, but they share an important principle: understanding the impact of your choices is more useful than making assumptions about which options are sustainable.
Trend | What it means for organisers | What you could measure or review |
Carbon measurement | Collecting emissions data as part of event planning | Travel, energy, catering, freight and accommodation |
Circular production | Reducing unnecessary new materials and considering reuse | Material quantities, reuse and disposal |
Smarter energy use | Reviewing power demand and supply options | Electricity and fuel consumption |
Supplier collaboration | Involving partners in environmental planning | Supplier activity data and data quality |
Structured management | Creating a repeatable approach across events | Objectives, responsibilities and progress |
Evidence-based claims | Supporting environmental statements with appropriate information | Calculation methods, assumptions and comparisons |
1. Carbon measurement is becoming part of event planning
Carbon measurement helps event organisers understand where greenhouse gas emissions are coming from, making it easier to identify priorities and evaluate potential changes.
An event's carbon footprint can include emissions associated with attendee travel, accommodation, venue energy, catering, freight, production materials and waste. These activities vary considerably between events, which is why a decision that matters for one event may have relatively little impact at another.
Imagine you're organising a conference and considering replacing printed materials with digital alternatives. That may be worth exploring, but what if a large proportion of your attendees are travelling internationally? Understanding the different sources of emissions can help you decide where to focus your efforts.
At Scope, we encourage organisers to start collecting information early rather than waiting until an event has finished. When you know what data you'll need, you can ask the right questions while suppliers, venues and attendees are still involved in the planning process.
Our Event Carbon Tracking software is designed to help organisers bring information from different areas of an event together, including travel, energy, waste, catering and production. This can make it easier to understand which activities contribute to an event's footprint and where further investigation may be useful.
For a more detailed explanation of the measurement process, our guide to how to measure and reduce your event carbon footprint explores the main emissions sources and how to approach collecting the relevant information.
What should organisers do?
Begin with the activities most relevant to your event, establish what information is available and identify where estimates may be necessary. The aim is to build a useful picture of emissions while being transparent about any gaps.
2. Circular event production is encouraging smarter material choices
Circular event production aims to keep products and materials in use for longer, reducing the need to manufacture new items and helping organisers avoid unnecessary waste.
Temporary event builds can involve staging, exhibition structures, flooring, graphics, furniture and decorative materials that are only needed for a short period. Designing these elements with future use in mind can create opportunities to reduce material consumption.
For example, modular exhibition structures may be suitable for multiple events, while reusable signage can avoid the need to produce entirely new graphics each time. Hiring existing furniture or production equipment may also be worth considering instead of purchasing new items for a single event.
However, reuse alone doesn't guarantee a lower carbon footprint. Transport distances, storage, cleaning, maintenance and the number of times an item is used can influence its overall impact.
This is an important distinction when reviewing sustainability trends in events. A material might be described as recycled or reusable, but those descriptions don't tell you everything about the emissions associated with producing, transporting and using it.
Material choices also connect to the wider supply chain. Understanding how products and equipment reach an event can help organisers assess the implications of purchasing, hiring and transportation. Our guide to tracking your Scope 3 supply chain for events explains what information is useful to collect from suppliers.
What should organisers do?
Ask whether a new item is necessary before choosing between products. Where alternatives are available, consider their expected lifespan, transport requirements and what will happen after the event.
3. Event energy planning is moving beyond the power source
Smarter event energy planning involves understanding how much power an event needs, when it needs it and which supply arrangements are suitable for the venue and equipment.
Lighting, audio systems, screens, catering equipment and temporary installations all require energy. The right setup depends on the event's location, technical requirements, available infrastructure and operating schedule.
Organisers may have opportunities to consider grid electricity, battery storage, generator arrangements or equipment that uses less energy. However, it's important to assess these options in context rather than assuming a particular technology is always preferable.
For instance, battery storage can have different environmental implications depending on how the electricity used to charge it is generated. Similarly, generator emissions depend on factors including fuel consumption and operating conditions.
Sometimes the most useful question isn't whether to change the power source, but whether the event could avoid using unnecessary energy in the first place.
If your event uses temporary power, understanding fuel consumption is an important part of carbon measurement. Our guide to calculating event generator emissions explains what information to request from suppliers and why fuel actually consumed matters more than simply recording that a generator was used.
What should organisers do?
Speak to your venue and technical suppliers about expected electricity and fuel consumption. Review operating hours, equipment requirements and opportunities to collect actual usage data.
4. Supplier collaboration is becoming central to event carbon reporting
Supplier collaboration helps event organisers access information about activities they don't manage directly, from catering and freight to venue energy and production materials.
An event is rarely delivered by one organisation. Venues, caterers, production companies, transport providers and other partners contribute to the event experience, and many also hold information needed to understand its environmental impact.
For example, a production company may know how much material was used in a temporary build, while a transport supplier can provide journey information. A venue may be able to share energy data, and a caterer may have details about meal quantities and food waste.
Supplier collaboration is one of the event industry sustainability trends worth prioritising in 2027 because it can help organisers collect more useful environmental information from the businesses delivering their events.
At Scope, we recognise the importance of bringing this information together rather than leaving it scattered across emails, spreadsheets and supplier records. Scope's event tracking software allows suppliers to enter data directly and enables team members to contribute information, helping organisers coordinate the process.
The quality of the information still matters. Supplier estimates should be identified as estimates, and missing information shouldn't be presented as though it has been measured.
Catering is a useful example because organisers may need information about meal types, quantities and food waste from an external provider. Our article on how to measure event catering emissions explains how this information can contribute to an event's wider carbon footprint.
Attendee information also deserves attention. Our guide to how to start tracking attendee travel emissions shows how planning data collection before an event can help organisers gather more useful information about guest journeys.
What should organisers do?
Include relevant environmental data requirements in supplier briefs and explain when the information will be needed. Start with realistic requests, then develop the process as your team and suppliers become more familiar with it.
5. Event sustainability management is becoming more structured
Structured event sustainability management means setting clear objectives, assigning responsibilities and reviewing performance instead of relying on individual initiatives that may be difficult to repeat or evaluate.
This approach is particularly useful for organisations delivering multiple events, where different teams and suppliers may otherwise collect information in inconsistent ways.
One relevant reference is ISO 20121:2024, the international standard for event sustainability management systems. The standard covers environmental, social and economic considerations and can apply to events of different types and sizes.
Importantly, ISO 20121 is not simply a carbon footprint calculation method. It addresses how sustainability is managed across event-related activities, including how organisations establish and improve their processes. Using ideas from the standard does not, by itself, mean an organisation is certified or has demonstrated conformity.
For an organiser managing an annual conference, a structured approach might involve agreeing on environmental objectives, requesting consistent supplier information and reviewing the results after each edition.
The same principle can apply to smaller events. A straightforward process that people understand and follow can be more useful than an ambitious plan that never becomes part of everyday delivery.
For businesses organising events alongside their everyday operations, it's also worth understanding how the two areas relate. Our article on managing business and event carbon tracking in one system explores the relationship between organisational emissions and event-specific measurement.
What should organisers do?
Decide which environmental and wider sustainability issues are relevant to your event, assign responsibilities and establish a consistent way to review what happened and what could improve next time.
6. Environmental claims are facing greater scrutiny
Evidence-based environmental communication means making claims that accurately reflect what an event has achieved, what has been measured and where uncertainty remains.
Organisers may understandably want to share their progress, particularly when clients, attendees or stakeholders ask about environmental performance. However, terms such as 'green', 'carbon neutral' or 'zero impact' can create misleading impressions if they aren't properly supported.
The UK Competition and Markets Authority's Green Claims Code explains how businesses should approach environmental claims under consumer protection law. Its guidance emphasises clarity, accuracy and appropriate evidence.
This matters when communicating event results. Saying that an event's travel emissions were measured is not the same as saying they were reduced. Equally, a lower calculated footprint compared with a previous event doesn't automatically prove that an organiser's actions caused the difference.
Changes in attendance, event duration, location, data availability or calculation methods can all affect comparisons.
At Scope, we believe this is an important part of responsible carbon tracking. Measurement can help organisers understand their impact and identify potential improvements, but it shouldn't be confused with a guarantee of emissions reductions.
What should organisers do?
Be specific about what you've measured, explain any significant assumptions and avoid making claims that go beyond the available evidence.
How Can Event Organisers Put These Trends into Practice?
The most useful sustainable event trends are those that help organisers make better decisions, rather than simply adding another task to an already busy event schedule.
You don't need to tackle everything at once. A manageable approach is to start with the information and decisions that are most relevant to your event.
Before the event: Review the venue, travel arrangements, production plans and supplier requirements, and decide which environmental data you'll collect.
During the event: Record relevant activity information, coordinate with suppliers and note any gaps or changes to the original plan.
After the event: Calculate emissions where appropriate, review the results and identify potential improvements for future events.
For example, if attendee travel is an important part of your event's footprint, our guide to sustainable event guest travel strategies explores ways organisers can consider travel earlier in the planning process.
If you're also collecting information about food, waste and other attendee-related activities, our article on measuring the key areas of your attendees' carbon footprint provides a more detailed starting point.
The wider lesson from these sustainability trends in events is that environmental performance depends on the decisions made across the whole event, not just the initiatives that are most visible to attendees.
Frequently Asked Questions about Event Sustainability in 2027
What is the biggest sustainability trend in the events industry?
Carbon measurement is one of the most useful developments for event organisers because it provides information about where emissions arise and helps teams evaluate potential improvements. However, the most important priority will depend on the event's activities, location, scale and available data.
How can a small event become more sustainable?
Smaller events can begin by considering travel distances, venue energy, catering quantities and material requirements. Collecting basic information about these activities can help organisers identify opportunities to avoid waste and potentially reduce emissions, without needing to implement every initiative at once.
How do you know whether an event sustainability initiative has worked?
To assess an initiative, organisers need relevant information before and after the change, along with a fair basis for comparison. For carbon emissions, this means using appropriate calculation methods and accounting for differences in event size, activities and data quality. Environmental benefits shouldn't be assumed simply because an alternative is labelled sustainable.
What Should Event Organisers Take From These Trends?
The most important message from the event industry sustainability trends discussed here is that meaningful progress depends on understanding how an event operates and making informed choices across its planning and delivery.
Carbon measurement, material reuse, energy planning and supplier collaboration can all support that process, but the right approach will vary from one event to another.
For Scope, this is why we place so much importance on helping organisers understand their carbon data. When you can see where emissions are coming from, you have a better starting point for deciding what to change and how to assess the results.
As event organisers prepare for 2027, the focus should be on understanding which sustainability initiatives are relevant to their events and how their impact can be measured.
At Scope, we'll continue reviewing event sustainability trends each year, sharing practical guidance to help organisers make informed decisions as approaches, expectations and available information develop.
