Sustainable event certifications and carbon footprint calculation

Sustainability management in events is not just a trend. It is a growing expectation from teams, clients, and markets, which increasingly value companies that act in a way that is consistent with what they say.

At The Yellow B, we help you manage everything related to certifications and carbon footprint calculations in Barcelona—for all companies that want their positive impact to be real, measurable, and communicable, not just a statement of intent in the footer.

How We Help You Make Your Event More Sustainable

  • Assessment and Impact Goals → Before designing anything, we analyze the starting point: the type of event, the number of attendees, the participants’ backgrounds, the planned venue, and the client’s expectations regarding sustainability. Based on this, we define the event’s impact goals and the criteria that will guide every decision moving forward.

  • Sustainable Event Design → We integrate sustainability starting with the creative concept: venue selection, set design using reusable or recycled materials, digital communication, catering management based on local and seasonal criteria, and the reduction of any single-use items. Sustainability isn’t an afterthought—it’s built in from the very beginning.

  • Responsible Production and Suppliers → We work exclusively with suppliers certified under our Security & Responsibility Framework™, which includes ethical, environmental, and social responsibility criteria. We manage the event’s supply chain with full traceability, ensuring that each supplier meets the standards the client expects and that the company can communicate.

  • Impact Measurement and Reporting → At the end of the event, we provide an impact report detailing the project’s sustainability metrics: carbon footprint generated and offset, waste managed, percentage of local suppliers, positive impact initiatives implemented, and any other indicators relevant to the client. Real, verifiable, and communicable data.

True sustainability in events begins long before the day of the event

The selection of suppliers, design decisions, waste management, impact measurement, and the ability to report on it using real data.

What's Included in Our Sustainable Events Service

We incorporate sustainability into every phase of the event, from the briefing to the post-event impact report.

This includes:

  • Event design based on sustainability criteria from the concept stage onward
  • Management of approved suppliers based on ethical and sustainable criteria

Our Certifications and Commitments

Sustainability is not a promise; it is a standard of practice that we apply to every project and that is backed by verifiable certifications and commitments.

Our sustainability framework:

  • Eventsost Certification: the benchmark standard for sustainable event management in Spain, which endorses our methodology and processes
  • ISO 20121 in progress: an international standard for sustainable event management, which we are in the process of obtaining to strengthen our standards at the European level
  • AEVEA members: committed to its Code of Ethics and Best Practices, which includes criteria for responsibility and sustainability in event management
  • Carbon Offsetting: We work with verified offset projects, such as the Amazon conservation project in Madre de Dios, Peru, through which we offset the emissions from the opening ceremony of the Toulouse Business School campus in Barcelona

These commitments are not internal documents. They form the basis of how we work and serve as a guarantee for clients who need their events to be truly sustainable.

Frequently Asked Questions About Sustainability Management

A sustainable event is one in which sustainability is integrated as a management criterion from the very beginning, not as a cosmetic afterthought at the end. This involves decisions regarding design, supplier selection, waste management, catering, communication, and impact measurement. A truly sustainable event can be demonstrated with data, not just with good intentions.

Not necessarily. Some sustainable decisions lead to savings—such as reducing single-use materials, opting for digital communication, or choosing local suppliers to lower transportation costs. Others involve additional costs, such as emissions offsetting or supplier certification. In all cases, we guarantee complete transparency regarding the economic impact of every sustainable decision.

Yes. We provide a post-event impact report with verifiable metrics that the client can use in its internal and external communications. For companies that need to demonstrate the sustainability of their events to their stakeholders or in their sustainability reports, this report is a ready-to-use tool.

Not at all. Sustainability and creative excellence are not incompatible; in fact, some of the most original ideas we have developed stem precisely from sustainable constraints. Using natural materials, choosing venues with a rich history, or designing local culinary experiences yields more authentic and memorable results than standard solutions.

Yes, we incorporate sustainability criteria into all types of events we organize: conventions, kickoffs, conferences, incentive trips, trade show booths, and brand events. The scale and level of implementation are tailored to each project, but our commitment remains the same in every case.
