Sustainable events: organize eco-friendly meetings

Sustainability has become a necessary factor in all industries, including the world of events. It has gone from adding extra value to each project to becoming a fundamental strategy in companies. Based on this paradigm, sustainable events not only align with environmental policies, but also reinforce the image of the brands that promote them.

What is a sustainable event?

To be able to organize a sustainable event it is crucial to know what such an event is based on, since it is not just about implementing practices that care for the environment.

A sustainable event is one that from the outset is developed and designed to minimize its environmental, social, and economic impact.

Key principles of a sustainable event

Implementing sustainability from the design will be key to carrying out a sustainable event, and the following factors must be taken into account:

Waste reduction

• Avoid any type of single-use material and prioritize recyclable or digital materials instead.
• Reusable decorations.
• Sustainable, digital, or practical gifts.
• Elimination of printed brochures, using mobile apps or QRs as a better option.

The key to waste elimination will be to think circularly.

Responsible transport

One of the main sources of pollution at events is private transport, which generates large amounts of CO₂. Promoting sustainable and responsible mobility is a very effective way to reduce emissions.

• Encourage the use of public transport or carpooling.
• Select accessible locations without the need for a car.
• Provide information on eco routes.

Efficient energy use

Lighting and climate control will be a basic aspect in the setup and execution of a sustainable event.

• LED lighting.
• Smart climate control.
• Use of natural light.
• Renewable energy sources.

Conscious catering

Catering is a fundamental aspect of environmental and social impact, so thinking about local and mindful menus would be the right choice.

• Local and seasonal suppliers.
• Vegetarian and vegan options.
• Eliminate single-use plastics.
• Minimize food waste.

Inclusion

A sustainable event must also be inclusive and socially responsible.

• Accessible for people with functional diversity.
• Respectful of local culture and communities.
• Promoter of equity and fair work.

Common mistakes when planning a sustainable event

Integrating sustainability cannot be focused only as a marketing strategy, which is why there are some common mistakes that can be avoided:

Greenwashing: What it is and how to avoid it

Greenwashing is a marketing strategy used by companies to appear more environmentally friendly than they really are; that is, to make users and consumers believe that the company’s practices are sustainable, when in reality they continue with practices that degrade the environment.

How to avoid greenwashing?

• Provide verifiable evidence: provide verifiable data from reliable and real sources.
• Communicate with transparency: the key to avoiding greenwashing is to be transparent and honest. Also, it is advisable to communicate not only achievements, but also the challenges encountered along the way.
• Do not exaggerate achievements or data: do not use ambiguous or exaggerated words, and support achievements with real data.

Lack of real measurement

It is crucial to correctly measure the impact generated through the activity carried out, since without metrics there is no real sustainability. In order to verify that an event is sustainable, it is crucial to measure:

• Amount of waste generated and recycled.
• Carbon footprint from transport.
• Energy savings.
• Participant satisfaction.

Underestimating logistics

Changing suppliers, coordinating green transport, or choosing responsible catering requires more planning. Every decision made in logistics has a great environmental impact.

Some of the factors that usually go unnoticed are:

• Prioritize the use of modular and reusable materials in the setup to avoid single-use structures.
• Opt for hiring local suppliers to reduce the carbon footprint generated by the transportation of equipment and staff.
• Availability of clearly marked and well-distributed recycling points throughout the venue, for proper waste management by attendees and staff.

How to measure the sustainability of an event

Measurement is fundamental, not optional. Digital tools facilitate thorough monitoring to optimize future initiatives.

Key indicators

• % of recycled waste.
• CO₂ emissions per attendee.
• Energy consumption.
• Amount of reused materials.
• Percentage of food wasted.

Digital tools for traceability

There are multiple tools to plan and evaluate the sustainability of your event in a precise and professional way:

• GES (Green Event Scorecard)
• EventSost
• Trace My Event

Trends in sustainable events

The MICE sector in 2025 is adopting ecological and innovative practices. These are some of the most consolidated trends.

Paperless events

Digital management of accreditations, agendas, tickets, and surveys optimizes the user experience and reduces deforestation and generated waste.

Reuse of materials and scenography

Companies have started to save resources in scenography. Ephemeral setups are giving way to modular, recyclable, or multipurpose solutions; in this way, material consumption is reduced and less waste is generated.

Sustainability certifications for events

Some recognized certifications that guarantee good practices:

• ISO 20121 (Sustainable event management)
• BREEAM Events
• EMAS (Eco-Management and Audit Scheme)
