Quick tips for choosing an “eco” Maldives resort

• Look for measurable credentials and programs, not just marketing: EarthCheck/Green Globe/Green Key listings, PADI Eco Centre / Adopt‑a‑Reef involvement, on‑site marine‑biology teams, coral nurseries, and third‑party awards or press coverage. (gili-lankanfushi.com)
• Check plastics & water policy: resorts that bottle desalinated water in reusable glass and use refillable amenities cut huge plastic waste (many on this list do). (comohotels.com)
• Marine‑focus vs. carbon focus: some properties emphasize coral/turtle conservation and guest participation (reef nurseries, cleanups), others emphasize renewable energy and carbon‑tracking/offsets — decide which matters most to you. (press.fourseasons.com)
• Ask specifics before you book: current certification level, percentage of energy from renewables, plastic‑bottle policy, on‑island water treatment, waste‑management approach, and how guest activities support (or harm) reefs. (sixsenses.com)

If you want a shorter shortlist by focus (best for coral‑restoration, best for low‑plastic operations, best for on‑site research labs, or best family programs), tell me which focus and I’ll narrow these down further.
