Sustainable Event Planning: How Small Changes Make a Big Impact

Why Sustainable Event Planning is More Critical Now Than Ever

Events are a unifying factor; they inspire and create memorable experiences. But conventionally, they have also created a lot of waste, single-use decorations, uneaten food, and excessive energy use. The good news? There is increased awareness, and both clients and guests are demanding that events be environmentally responsible.

Deciding to collaborate with sustainable event planning businesses is not merely about cutting carbon footprints. It is all about aligning your brand with values that appeal to stakeholders, employees, and clients. By showing that you are a serious organisation in sustainability, you are telling a great story about yourself. Individuals recall that, and it creates credibility and a relationship on a scale far greater than what actually happened on the day of the event.

Simple Steps to Embrace Eco-Friendly Event Planning

To begin with, eco-friendly event planning companies do not need an unlimited budget. With a few areas of concern and a team of time-tested partners, you can significantly reduce your event’s environmental impact while improving the attendee experience.

1. Smart Sourcing: Accessibility, Energy and Venue

The venue and mode of entry for attendees are significant factors in the event’s impact.

• Venue Vetting and Optimisation: At SEVEN, we would focus on venues that have successfully passed recognised sustainability certifications (such as ISO 20121 or BREEAM), as well as those utilising 100% renewable energy. We do not rely solely on a checklist; we actively collaborate with locations that have strong waste management infrastructure and already have energy-efficient systems in place (such as intelligent HVAC).

Indicatively, in the case of sourcing a large conference venue, our analysis would be based on the ease of access; i.e. the public transport and the efficiency of the lighting, which in turn would actively favour a sourcing of a venue in the central areas, which are readily accessible by rail or tube and hence minimise the use of delegate car transport.

• Delegating De-carbonised: We know that global travel cannot be avoided. SEVEN, an established event management company in London, offers a clear choice for carbon offsetting through verified projects. This cost can either be included in ticket prices or in corporate budgets to ensure the required travel footprint for your event is ethically considered.

2. Reduction, Waste, Materials and Design

The biggest change that you can implement is addressing material waste, whether it is signage or swag.

• The Digital-First Mandate: We encourage a rigorous digital-first approach. We get rid of redundant printed programmes, brochures, and even name badges and use NFC-powered digital passes and event applications. In situations where physical resources are necessary (such as high-impact signage), we will use recyclable or compostable resources such as cardboard or fabric graphics, and all of it will be reclaimed at the end of the event.

• Careful Gifting and Swag: Ditch disposable gadgets and pens. SEVEN curates include welcome packs with locally sourced, ethical, or upcycled items, such as bamboo coffee cups, seed paper notepads, or artisanal food items from social enterprises. This makes your takeaways high, the impact is low, and it benefits the local economy.

3. Conscious Consumption: Food and Beverage (F&B)

Catering offers one of the best opportunities to implement impactful, sustainable event planning.

• Local, Seasonal, and Plant-Based Menus: We demand menus that are constructed from locally sourced, seasonal produce and that significantly reduce transport emissions. We usually work with top-tier, imaginative vegetarian and vegan items that become the highlight of the product and reduce the use of meat and dairy, which consume resources. For example, instead of a generic buffet, we can create a zero-mile tasting festival featuring locally sourced foods from around London.

• Advanced Food Waste Management: In collaboration with our catering partners, we have high food waste tracking. We remove any single-use condiments and serving containers, and, most importantly, any unnecessary excess food that cannot be avoided is ethically given to local charities via schemes such as FareShare rather than going to landfill.

4. Management of Water and Resources

Smart allocation of water and material resources is crucial, though it is usually ignored.

• Plastic-Free Policy: We implement a policy to eliminate plastic from beverages. This requires having filtered water stations throughout the venue, and attendees are reminded to carry reusable bottles (which are often included in the sustainable swag). We also liaise with caterers to make sure that all beverages are served in reusable glasses or aluminium cans.

• Power Down Policy: When planning a big event, we collaborate with AV teams to plan power-down moments for non-essential lighting and equipment during breaks and overnight, and to manage energy use effectively to lower demand and reduce carbon emissions.

5. Measuring Impact with Data

Sustainability is a process, and proper statistics are the roadmap.

Post-Event Reporting and Benchmarking: As professional sustainable event planning agencies, SEVEN offers detailed, quantitative reports that breakdown the environmental performance of your event. It will involve estimating the carbon footprint of travel, energy, and materials, as well as indicators such as waste diversion rates. 

This is then compared with past performance to help you achieve and surpass your corporate ESG (Environmental, Social, and Governance) objectives on an annual basis.
