On 13 September 2023, the Green Key certification event took place at Camino Real Polanco in Mexico, with 32 hotels under the Camino Real Hotels group (Camino Real, Quinta Real, and Real Inn brands) being certified.

In attendance were prominent figures from the tourism and hospitality sector in Mexico, including Miguel Torruco Marqués, the Secretary of Tourism; Humberto Hernández Haddad, the Undersecretary of Tourism; Dr. José Zeind Domínguez, the General Director of Tourism Certification; Leandro Trejo Escudero, the General Director of Camino Real Hoteles; and Joaquín Arturo Díaz Ríos, the CEO of FEE México.

In his opening remarks, Mr. Ríos emphasized that "Green Key is not merely a recognition; it is the result of the significant technical support and strong commitment demonstrated by each and every department within the hotels during its implementation."

As part of their implementation efforts, Camino Real Hoteles successfully reduced electricity, water, and gas consumption by 7% compared to 2019. Despite a 2% variation in occupancy compared to 2019, electricity consumption saw a remarkable 13% reduction, resulting in a decrease of 3,320 tons of CO2 emissions. This is equivalent to planting 276,000 trees in just one year.

Moreover, this achievement involved collaboration with over 200 suppliers from across the country, all of whom pledged to adhere to Green Key guidelines. In the process, more than 3,500 employees actively participated, receiving 96 training sessions on environmental issues, which were a central focus of the program.

In his closing remarks, Miguel Torruco Marqués, Secretary of Tourism, extended his congratulations to the establishments and emphasized that "Green Key represents a guarantee of sustainability in the management and operation of accommodation, as demonstrated by Grupo Posadas."
