Why are there 200 certifications and none of them is specialized for Vacation Rentals?

I have been involved in the vacation rental industry for many years. In fact, I created one of the first online bookable platforms for short-term rentals globally, even before Airbnb emerged. Later on, I co-founded a channel manager that Airbnb became a client of.

After I left my position as Chief Marketing Officer at Rentals United in late 2021, I hoped to combine my passion for eco-friendly living with my expertise and connections in the vacation rental industry. To my surprise, there were 200 sustainability certifications for hotels and none for our industry.

This led me to create Sustonica, which aims to unite the vacation rental industry under a common banner and inspire guests to adopt sustainable practices.

It was not an easy journey, but after over a year of hard work and the support of an incredibly passionated team, we were able to bring all the pieces of the solution together.

“STR sustainability is “a very confusing world as you may find lots and lots of contradicting information,” de Souza Lage says. The industry needs “one certification, not 201 certifications” like the hotel industry, in which the vast array of sustainability certifications only serve to “confuse customers,” she says.”

“The hotel industry needs to cut carbon emissions by 66 per cent per room by 2030 to counteract emissions corresponding to growth. These types of figures are not yet available for the vacation rental industry, but we can already come together as an industry and start cutting our carbon emissions wherever possible.”
