Meet the Team

Rebecca Johnson

Sustainability Consultant

Rebecca’s passion for boosting the legacy and countering the negative impacts of tourism and events has led her on a fast and (sometimes) furious journey in recent years, fine tuning her sustainability knowledge and experiences to become an expert in her field.

With a full bundle of qualifications under her belt (ISO 20121, ISO 14001, GSTC, Travelife Auditor, GRI, Biosphere, Sustainable Event Alliance accreditation), Rebecca is well equipped to guide the full range of destination stakeholders in their mission to develop and implement a sustainability strategy. As a multilingual Brit (Spanish, French, German, Catalan) who has been living in Barcelona for 15 years, and working in events for 18, Rebecca has thrived in the international Event Management sector. Her roles in Trade Fair Management, Event Production, Meetings, Incentives and Congresses have all allowed her endless opportunities to learn, grow and meet people from different cultures and backgrounds.

Rebecca supports the GDS-Index will a mission to drive the benchmarking of destinations, while developing and implementing strategic consulting solutions for DMOs, CVBs, venues and events. Not content with sufficient event management at work, Rebecca can also be found organising food and wine excursions to promote Catalan food heritage in her spare time.
