How to write an event sustainability policy

Write an event sustainability policy by defining which events it covers, what you commit to, who can make decisions, and how you'll fund and review the work. Keep it specific enough to guide a booking or purchase, with a clear way to handle exceptions. A policy that nobody can use under pressure won't change your event.

So you've got a paid event to deliver, suppliers to confirm, and someone has asked for your sustainability policy. Maybe it's the venue. Maybe it's a sponsor. You open a blank document, type something about protecting the planet, and realise that sentence doesn't help you choose anything.

The first thing you want to do is write down the decisions your team keeps getting stuck on. Reusable serviceware sounds sensible, but who pays for washing? Public transport sounds great, but does it run after your headline act? Start there. Your policy needs to survive the event you're actually producing.

This guide walks you through the scope, commitments, responsibilities, budget, exceptions and review that make a policy usable. You'll also find an adaptable example and a way to test your wording against awkward decisions. The aim is a document your team can follow and your business can afford to honour.

Know what your policy needs to do

A policy states the rules and commitments that remain consistent across your event decisions. An action plan turns those commitments into tasks, deadlines and event specific targets. Keep them connected, but don't cram every delivery instruction into the policy. Your bar manager needs a clear rule, then the instructions for applying it.

For example, the policy might say you prefer reusable drinking vessels where safe collection and washing can be arranged. The action plan identifies the supplier, collection points, staffing and return arrangements. If those arrangements aren't possible, your exception process tells the manager who decides what happens instead. Nobody has to interpret a slogan.

The policy also gives buyers, partners and suppliers a fair account of your intentions. It shouldn't imply that writing the document makes the event sustainable. You're describing what the business undertakes to do, including how it checks delivery. Whether you delivered is a separate question, answered with evidence after the event.

ISO 20121:2024 treats event sustainability as management of environmental, social and economic impacts, and applies to events of different types and sizes. That's a useful starting point. Your policy can cover the people doing the work and the event's financial health alongside its environmental effects.

You don't need to claim conformity with the standard to write a useful policy. Using its general approach doesn't establish certification either. If a partner requires a particular certification or assessment, ask exactly what they need before promising it. This article offers practical drafting advice, rather than a substitute for the standard's full requirements.

Define the events and decisions it covers

Start with your business name and the events covered. Is this a policy for one festival, a venue's entire programme, or a series of paid workshops? Say so. A company policy that quietly applies only to the easiest event creates confusion when your team takes on a different format.

Include the activities you commission around the public event. Think about venue selection, purchasing, production, staffing, catering, travel arrangements, promotion and clearing the site. The document doesn't need a detailed checklist for each stage. It needs to establish whether those decisions fall within its rules, so nobody assumes the policy starts when doors open.

Separate what you control from what you influence. You can specify what your own caterer buys. You may have limited control over a shared venue's heating system. You can provide useful travel information to ticket buyers, but you can't dictate every journey. Make your commitments match those differences instead of pretending everything is under your control.

Describe how hired venues and independent traders participate. A trader doesn't become your employee because they occupy a stall. They can, however, agree to conditions for operating at your event. Identify which policy commitments become supplier requirements and which need cooperation with another organisation. That distinction matters when you negotiate the booking.

Name any genuine exclusions and give the reason. If the policy doesn't yet cover an overseas partner event, explain that scope openly. Don't exclude a difficult activity just to make your claims prettier. A useful boundary tells your team where responsibility sits and tells readers what the document actually promises.

Listen before you choose the commitments

Your team will know where the promises break. Ask production what gets discarded, catering what drives overordering, and the venue what can change within the booking. Ask the person answering attendee questions what people need to know before buying. You want actual constraints, rather than a meeting where everyone agrees sustainability is important.

Include people who experience the event differently. An attendee who needs accessible parking can explain why a blanket instruction to leave cars at home doesn't work for everyone. A casual crew member may recognise unsafe turnaround times that management misses. A neighbour may identify delivery noise that never reaches your feedback survey.

You don't need a huge consultation exercise for a small recurring show. Short conversations and written questions can be enough to start. Record who you asked, the issue they raised, and whether you changed the draft. If you choose a different approach, explain why. Listening shouldn't create a promise to accept every suggestion.

The Events Industry Council's sustainable event standards cover environmental and social responsibility, including accessibility and supply chains. That breadth is a useful reminder when choosing topics. Cups and bins are visible, but they don't represent every consequence of your event. Read your draft with that wider responsibility in mind.

Choose commitments around the issues your event can meaningfully address. A touring production and a local evening workshop won't have identical priorities. Keep the policy broad enough to cover both where necessary, then put their different actions in their plans. Copying another event's priorities can leave your own biggest problems untouched.

Write commitments people can act on

Replace vague intentions with a decision rule. "We support sustainable purchasing" doesn't tell your buyer what to ask a supplier. "We consider existing stock, hire and reuse before ordering new event materials" gives them a starting point. They can explain why they bought something, and you can check whether they considered the alternatives.

State the limit where one exists. You might prioritise accessible venues that attendees can reach using public transport, while recognising that event timing and audience needs affect the choice. That is more useful than promising car free attendance. Be ambitious about decisions you make, and precise about outcomes you cannot guarantee.

For food, the US Environmental Protection Agency's Wasted Food Scale places prevention, donation and upcycling among the most environmentally preferable options for wasted food. Use that principle to avoid a policy focused entirely on disposal. Ordering and service decisions deserve attention before you decide what happens to leftovers.

Your commitment could require catering orders to reflect updated attendance estimates and an agreed service plan. Any surplus arrangements need practical checks for food safety, storage and collection. Don't write a donation promise before a recipient has agreed what they can accept. The organiser still has to make the arrangement work at this event.

Keep environmental preferences separate from essential safety and access requirements. Nobody should have to argue for drinking water or a necessary access aid against a headline reduction target. Say that directly. A policy becomes easier to follow when your team knows which requirements they must protect while finding a better way to deliver.

Put people and commercial reality in the document

Sustainability shouldn't give your business permission to save money by treating people badly. Include expectations for safe working arrangements, fair treatment and clear supplier terms. Be specific about the work you commission. A crew welfare commitment needs to affect schedules, facilities and who workers can contact when something is wrong.

The International Labour Organization's declaration on fundamental rights at work includes a safe and healthy working environment among its fundamental principles. Your policy can acknowledge that principle without pretending one paragraph verifies every contractor. Translate it into the checks and expectations your event business can actually apply.

Accessibility belongs here too. Commit to considering access during venue and service decisions, sharing accurate information, and providing a way to request help. Don't promise universal access if you haven't assessed the event. Our event accessibility checklist can help your team turn that commitment into practical planning questions.

Financial responsibility means budgeting for the commitments you approve. It doesn't mean every measure must save money immediately. Some changes cost more because they require staff time, equipment or a different supplier. Make the cost visible and decide whether the event can support it. A promise without an allocation is someone else's unpaid problem.

Keep the purpose clear. You're trying to run an event business that can continue delivering its commitments. That requires honest prices, reliable suppliers and decisions that fit the event's finances. Don't claim that sustainability automatically increases ticket demand or profit. You can judge the cost and benefit of each proposed change without inventing a commercial guarantee.

Give the owner authority and a budget

Name a policy owner by role, and name the senior person who approves it. In a small business, that may be the same person. The important part is that responsibility doesn't float around the group chat. Everyone should know who can resolve a disagreement and who follows up when an agreed action stalls.

Then distribute delivery. Purchasing checks belong with the person ordering materials. Catering commitments belong with the person managing that contract. Attendee information belongs with the person publishing it. Your policy owner coordinates and checks the work. They don't magically inherit every task that has an environmental or social consequence.

Write down what each person can authorise. Can the production manager change a supplier within the approved budget? Does a higher cost need the event director's approval? Who can stop a proposed claim appearing in advertising? If the team can't answer those questions, a named owner is still just a name.

Build the agreed costs into your event budget. Include setup, labour, collection, storage, cleaning and returns where they apply. Compare complete delivery costs when reviewing options. A hire quote that excludes collection isn't comparable with a purchase price that includes delivery, especially when your crew will spend hours sorting the difference.

Keep the resource commitment proportionate. A smaller promoter may need supplier checks and time for review, rather than a dedicated sustainability job. A larger festival may need specialist advice and additional staff. State how resources get approved, and connect any change in commitments to that approval. Don't let the policy silently grow beyond what delivery can support.

Make supplier requirements clear before booking

Your supplier brief should explain which parts of the policy affect that booking. A lighting supplier needs the requirements relevant to equipment and power. A catering supplier needs the food, serviceware and surplus arrangements. Sending everyone the whole document without clear expectations creates more reading, and still leaves the important agreement unfinished.

Ask for evidence that matches the requirement. If you need a waste destination confirmed, ask who accepts the material and what documentation you will receive. If you need reusable equipment, ask what is hired, how it is returned, and who covers damage. A supplier's general sustainability page doesn't answer those event specific questions.

Include the agreed requirements in the contract or booking documentation, with suitable advice where needed. Our guide to event catering contract terms covers the wider catering agreement. The policy supplies your expectations, but the actual arrangement still needs deadlines, responsibilities and a way to address a missed obligation.

Tell suppliers how to raise an exception before they arrive. Maybe the specified product is unavailable, or the venue doesn't permit the planned washing setup. You want that information while alternatives are possible. A supplier shouldn't discover at load in that your written preference was treated as an absolute condition they never agreed to.

Be realistic about leverage. You may not persuade a venue to replace installed equipment for one booking. You can ask questions, choose a different venue when feasible, or document the limitation and review it before renewing. The policy should make those choices deliberate. It shouldn't let your team promise changes only another business can approve.

Decide how exceptions work

Events need a route for difficult decisions. An exception is permission to depart from a policy requirement in a specific situation. It is not permission to ignore the whole policy. Define who approves it, what they need to know, and where the decision is recorded. Keep the process short enough to use during production.

Ask for the requirement affected, the reason, the alternatives considered, and the proposed response. Add any safety, access, cost or delivery consequences. A manager can then weigh the actual decision instead of reacting to "we can't do it". The record also helps the next team avoid discovering the same problem all over again.

Distinguish an emergency from a late request. If a safety incident requires an immediate change, the responsible lead should act under the event's emergency arrangements, then record the departure afterwards. If a supplier simply prefers cheaper packaging, there is time to ask for approval. Neither situation should vanish from the review.

Set limits on exceptions. They cannot authorise unlawful conduct or remove essential safety protections. They shouldn't override an access arrangement without a suitable alternative and the right decision maker. A policy exception is an internal decision, and it doesn't cancel obligations elsewhere. Check any regulatory or contractual question with someone qualified for your location.

Recurring exceptions reveal a design problem. If every event requires the same departure, review the requirement, resource allocation or supplier choice. Don't keep signing the same form and calling that progress. Either make delivery feasible or change the promise openly. Your document should describe the business you are building, rather than a business nobody can run.

Keep public claims narrower than your evidence

Treat the policy as a commitment document, and your results as evidence of delivery. Saying you aim to reduce wasted materials is different from saying the event produced no waste. Keep those statements separate. Marketing copy should never turn an intention into an achieved outcome because the stronger wording fits the campaign.

The UK Competition and Markets Authority's Green Claims Code guidance says environmental claims must be accurate, clear and supported, without hiding relevant information. It also addresses meaningful comparisons and consideration of the full life cycle. Its legal context is the UK, but the discipline is useful when reviewing your event's wording elsewhere.

Give someone responsibility for approving environmental statements in ticket pages, sponsor decks and attendee messages. They should check what the claim covers, what evidence supports it and whether qualifications are clear. "Reusable cups at the main bar" describes a specific arrangement. "A completely green festival" says much more than that evidence can establish.

Make qualifications easy to find. If an arrangement covers one area, name the area in the statement. If results are provisional, say so. Avoid burying a limitation in a separate report while the main advert creates a broader impression. A reader shouldn't need to investigate your wording to understand what you have actually done.

Keep promises to sponsors under the same control. Sponsorship revenue can help fund improvements, but it doesn't supply the evidence for a claim. Before signing, agree what you can report, who approves the wording, and when results will be available. You don't want a sales commitment forcing your team to publish a conclusion they can't support.

Use this adaptable event sustainability policy example

The following example shows how the pieces fit together for a hypothetical organiser running recurring paid events in hired venues. It is original sample wording, not a certified policy or a legal template. Replace the role titles and commitments with arrangements your business has checked. Remove anything you cannot support before approving it.

Purpose and scope

Our event business commits to considering environmental, social and financial consequences when planning and delivering paid events. This policy applies to events we organise, including the venue and supplier decisions, production, staffing, catering, attendee information and site clearance we commission. It covers our own decisions and the requirements we agree with event partners.

Where a venue, trader or other partner controls an activity, we will identify that responsibility and agree relevant expectations before booking. We will record significant limits on our control. We will not present excluded activities as having no impact, or imply that another organisation has accepted commitments it has not agreed to.

Our commitments

We will consider whether materials already owned, hired or reused can meet the event's requirements before purchasing new items. We will agree the handling and return arrangements needed for reuse. We will confirm the collection route before describing an item as recyclable or compostable within our event, and avoid unsupported claims about its disposal.

We will plan food orders around updated attendance expectations and the agreed service format. Where surplus food arrangements are appropriate, we will confirm practical acceptance, food safety and collection requirements with the parties involved. We will provide accurate journey information and assess transport arrangements against event timings, attendee needs and the options available locally.

We will consider accessibility when selecting venues and services, share known access information, and provide a contact route for requests. We will set expectations for safe working arrangements and fair treatment in work we commission. Safety, essential access needs and applicable obligations will remain protected when we consider environmental preferences or cost changes.

Responsibility and resources

The event director approves this policy and the resources needed to deliver it. The operations lead owns its implementation, explains relevant requirements to department leads and maintains the decision records. Department leads apply the requirements to their bookings and activities, raise constraints before commitment, and provide agreed records for review after the event.

Event budgets will include the costs and staff time needed for approved actions. Additional costs beyond a lead's spending authority require the event director's approval before commitment. We will consider complete delivery costs when comparing options. Any proposed policy change that needs additional resources will include a funding and staffing decision before approval.

Exceptions and communication

A department lead seeking an exception will identify the requirement, reason, alternatives and proposed response. The operations lead will review it with the event director where it affects approved spending or public commitments. Emergency action will follow the event's safety arrangements, with any relevant departure recorded afterwards. Exceptions cannot remove applicable obligations or essential protections.

We will share the policy with our team and communicate relevant requirements to suppliers before booking. Public statements will distinguish commitments from results and identify significant limitations. The operations lead will check environmental claims against available evidence before publication. Partners must agree event related claims with us before presenting them as statements about our delivery.

Review and approval

After each event, the operations lead will review delivery with department leads, including supplier records, feedback, costs and exceptions. The event director will approve necessary changes before the next booking decisions they affect. We will also review the policy when our event format, venues or important requirements change. We will retain approved versions and identify the current document.

Adapt the example to your event business

For a venue programme, keep the policy stable across shows and put visiting promoters' responsibilities in their booking terms. Your own staff may control the bars, while promoters control production purchases. Make that split explicit. Otherwise, each business can assume the other one is checking the same requirement, leaving nobody responsible for delivery.

For a touring event, avoid a universal promise about local infrastructure. Different venues may offer different collection systems, transport connections and access arrangements. Keep the shared policy rule, then document the local arrangement for each stop. You can require a confirmed disposal route everywhere without claiming that the same material works everywhere you visit.

For a small workshop business, remove responsibilities that don't exist. If you don't commission catering, you don't need a long catering commitment copied into every event plan. You may still need to choose an accessible room, describe travel options and control printing. Concentrate your effort where it changes something instead of maintaining irrelevant clauses.

Be careful with words that sound simple but carry several decisions. "Local suppliers" can mean a shorter delivery journey, support for nearby businesses, or a supplier with premises inside an arbitrary area. Those aren't interchangeable. Say which outcome you want and how you assess it. A nearby office doesn't prove the equipment travels from nearby storage.

The same applies to "affordable" or "inclusive". If you want to protect lower priced ticket options, decide what that means within your event budget. If you want people to request access support before purchasing, confirm the contact route actually works. Broad promises become useful when somebody can explain the choice they require.

Finally, read the policy beside your current supplier briefs and ticket information. Where the wording conflicts, resolve the actual arrangement before editing the document to sound consistent. That last check can uncover a commitment that was agreed internally but never reached the business expected to deliver it.

Test the draft against a real booking decision

Now put the document under pressure. Imagine a hired venue can support reusable cups at the bar, but its washing area is unavailable during your dates. Does the policy tell the bar lead what to do? They should identify the missing arrangement, explore alternatives, check costs and request a decision before confirming the order.

Another example is a show that finishes after the final train. A commitment to provide public transport information still matters, but the information needs to explain that timing. If you offer a shuttle, check its actual capacity and accessibility. The policy shouldn't encourage a marketing promise that your transport arrangements can't fulfil on the night.

Try a supplier failure too. Your agreed waste contractor can't collect a separate material stream, and the replacement offers mixed collection only. Who approves that change? Who removes any claim that depends on separate recovery? A usable policy connects the operational decision with the communication that must change, so the website doesn't keep making yesterday's promise.

Ask a department lead to work through one scenario without your explanation. If they need you to translate each paragraph, rewrite it. Keep the words they recognise from their role. "Ask the operations lead before changing the agreed serviceware" is easier to follow than language about ensuring alignment with organisational sustainability objectives.

This test also exposes missing resources. If every sensible response requires staff time you haven't allocated, the wording isn't the main problem. Change the delivery plan or approve the resource. You can write a shorter, honest commitment today and strengthen it when the business can support more. Making an impossible promise helps nobody.

Approve it, share it and use the review

Before signing, let the people responsible for delivery check their commitments and authority. Ask whether supplier agreements support the wording, the budget covers it, and the exception route is usable. Resolve disagreements before publication. A signature should confirm decisions the business has made, rather than create a fresh list of problems for production.

Give the policy an approval date, an owner, a version and a next review point. Those details help your team identify the current document. Put it somewhere department leads and relevant partners can access. Remove obsolete copies from active briefings so a supplier doesn't receive one requirement while the event manager works from another.

Explain what changes for each role. Your crew don't need a speech about every clause. They need to know which decisions they make differently, when to raise a problem, and whom to contact. Give temporary staff and volunteers the instructions relevant to their work. A document stored neatly still needs people who understand it.

Review delivery while the decisions are fresh, then revisit the document before the next important bookings. Ask what worked, where the policy created confusion, and which exceptions repeated. Separate a missed action from a requirement that couldn't be delivered. Those failures need different fixes, and neither improves because you add more ambitious language.

Writing an event sustainability policy starts with the event you can actually deliver. Define its scope, choose commitments your team can apply, give people authority and resources, and make difficult decisions visible. Then use the review to improve the next event. The policy earns its place when it changes a real choice before the money is spent.
