El Dorado Maroma in Mexico’s Riviera Maya has reached a significant sustainability milestone, earning EarthCheck Platinum certification after 10 consecutive years of certification. The latest audit was completed without observations, marking a decade of ongoing measurement, benchmarking and independent assessment of the resort’s environmental and sustainability practices. EarthCheck evaluates hospitality operations across areas including energy and water use, greenhouse gas emissions, waste and wastewater, ecosystem conservation, land use and social and cultural management.

The milestone reflects an approach that extends beyond individual environmental initiatives. Through Grupo Lomas’ Evolución Responsable framework, El Dorado Maroma’s sustainability efforts connect environmental stewardship with people, communities and responsible business practices. Programs across the wider organization include sea turtle conservation, native plant restoration, animal welfare and community initiatives, alongside the less visible work of managing resources, waste, purchasing and energy. Together, they illustrate how sustainability can become part of the operating structure of a resort rather than a collection of standalone guest-facing programs.

The Curated Take: The most interesting part of the Platinum designation is the decade behind it. Sustainability claims are increasingly common in luxury hospitality, but a 10-year certification history offers a different measure of commitment because progress is assessed over time rather than captured in a single initiative. For travelers who want luxury and environmental responsibility to coexist, that continuity provides useful context for understanding what happens behind the guest experience.
