Our Team

Eric Ricaurte – Founder & CEO

About Eric...

Eric founded Greenview as a boutique firm specializing in the metrics, measurement, and reporting of carbon and other sustainability performance indicators within travel & tourism. He is a frequent speaker, organizer, researcher, and generally ubiquitous character in the topic of sustainability measurement.

Eric began his career canoeing people through the jungle. He spent 10 years working in ecotourism across Costa Rica, Mexico and Brazil in operations and as a consultant. He started out managing eco lodges and nature park operations, and then naïvely decided to go on his own as an independent consultant. Eric built his client list to include hotels, parks, nature & cultural tour operators, receptive tour companies, and eventually destinations. During this time, he went 6 years straight without wearing a tie and his entrepreneurial ventures included co-owning a failed speedboat & outrigger canoeing tour business in Bahia, Brazil.

Throughout these formative years Eric spent plenty of time in forests and parks, and became fascinated with the concept of carbon sequestration for value it placed on nature and the opportunities it provided for conservation as well as tourism. He started researching the topic in 2001 and won a student research award at Cornell University for his paper titled “Carbon Offsetting, Trading, and Sequestration and their Relation to Travel & Tourism.” Fast forward 10 years later, as a research fellow at Cornell, Eric authored the study “Developing a Sustainability Measurement Framework for Hotels: Toward an Industry-wide Reporting Structure” and was selected as the technical consultant to facilitate the development of the methodology for the Hotel Carbon Measurement Initiative.

Throughout his career Eric has consulted globally for hotel properties; hotel companies; REITs; hospitality vendors; tourism operators, attractions and complexes; cruise lines; the UNWTO, WTTC, and AHLA; event organizers; and tourism destination organizations. Eric earned a Bachelor of Science degree from the Cornell University School of Hotel Administration and a Master of Science degree in Tourism & Travel Management from New York University.

Eric is a member of the UFI Committee on Sustainable Development, the International Standards Working Group of the GSTC, and on the judging panel of the HICAP Sustainable Hotel Awards. He has held a research fellowship at the Cornell University Center for Hospitality Research and been an adjunct instructor at the NYU University Tisch Center for Hospitality and Tourism. Eric is an active board member of the Orphaned Starfish Foundation. In his spare time, Eric still hangs out in forests and has enjoyed playing Capoeira for over 12 years.
