Palau
Pacific republic known for its passport pledge and a sanctuary closing 80% of its waters to fishing, now under pressure to reopen.
Palau is a Micronesian republic of 16 states with 17,614 residents at the 2020 census 1, and an ocean territory vastly larger than its land. It has built an international reputation on two policies: a marine sanctuary that since 1 January 2020 has closed 80% of its waters to fishing and mining 6, and the Palau Pledge, an environmental promise stamped into visitors' passports since December 2017 3.
Both are well documented as policies. Their outcomes are less so. The pledge's published results are mainly campaign and agency-survey metrics 14, and the sanctuary has faced repeated proposals to reopen large parts of it to commercial fishing, most recently in 2025 8. Tourism, which accounted for an estimated 40% of GDP in 2023 9, is recovering after near-collapse during the pandemic, and with it the $100 visitor fee that helps fund conservation 911.
Geography and cultural context
Palau is divided into 16 states and had 17,614 residents at its 2020 census, according to figures from the national Bureau of Budget & Planning 1. Customary governance remains active alongside the constitutional state: the Council of Chiefs has an advisory role, and traditional chiefs take part in public debate, including on the ocean 45. A central customary practice is bul, a moratorium by which chiefs close fishing grounds to let stocks recover; it has been invoked both to explain the Palau Pledge 3 and, by the president himself, to argue that closures should be used only when fish populations are threatened 4. In 2025 High Chief Reklai described the national marine sanctuary as both an enacted law and a bul, which in his view means it can be changed only by Palau's leadership collectively 5.
Landscape and ecology
The Rock Islands Southern Lagoon, inscribed as a World Heritage site in 2012 under both natural and cultural criteria, covers 100,200 hectares and includes 445 uninhabited limestone islands and 52 marine lakes, the highest concentration anywhere 2. The IUCN's 2025 assessment rates its outlook "good with some concerns", but rates climate change, tourism and invasive species as high threats, flags corals and marine lakes as of high concern, and describes the marine lakes as deteriorating 2. Offshore, the Palau National Marine Sanctuary covers about 475,000 km²; 80% has been closed to extractive activity since 1 January 2020, while 20% remains a domestic fishing zone 6. Local fishers and a tour operator have reported more tuna, dolphins and whales near the main islands since the closure, though these are anecdotal accounts rather than survey results 7.
Culture and heritage
The Rock Islands are also a cultural landscape. The World Heritage listing covers remains of stonework villages, burial sites and rock art reflecting about three millennia of island community organisation; the villages were abandoned in the 17th and 18th centuries 2. Customary institutions continue to shape conservation debate: the Council of Chiefs and the group Rubekul Belau called for meaningful consultation before any changes to the marine sanctuary in 2022 15, and traditional leaders joined conservation groups in opposing the 2024 proposal to shrink it 4. The Palau Pledge itself is addressed to the children of Palau and was framed at launch with reference to bul 3. We found few published sources in which Palauan communities assess the pledge in their own terms.
Tourism model and development
Arrivals peaked at 168,770 in 2015 and fell to 9,247 in 2022 9; the Palau Visitors Authority recorded 71,681 in 2025, up from 56,184 in 2024, with China, Taiwan and the US and Canada the largest markets 11. The Pristine Paradise Environmental Fee, set at $100 per departing passenger aged 13 and over with Palauan citizens exempt 10, has been collected since 2018, by airlines from air travellers and by Customs from sea arrivals 9. Of each $100, $10 goes to the Fisheries Protection Trust Fund supporting the sanctuary, $12.50 to the states, $25 to the airport, $30 to the Green Fee and $22.50 to the treasury 10. The Green Fee funds a network of 39 protected areas but covers only about 58% of their management costs 9. The Responsible Tourism Education Act of 2018 underpins the passport pledge and banned listed reef-harmful sunscreen chemicals from 2020 1213.
Initiatives and their evidence
| Initiative | Led by | What it is | Evidence |
|---|---|---|---|
| Palau Pledge | Palau Legacy Project with the Republic of Palau (agency: Host/Havas) | Since 7 December 2017 arriving visitors sign a pledge stamped into their passports and watch a mandatory in-flight film. Results reported are campaign metrics and an agency survey; no independent evaluation of behavioural or ecological outcomes has been published.31314 | Documented |
| Palau National Marine Sanctuary | Republic of Palau | Legislated in 2015; 80% of national waters closed to fishing and mining since 1 January 2020, with 20% reserved for domestic fisheries. Proposals in 2024 and 2025 sought to reduce the no-take area to 30% or 50%.648 | Documented |
| Pristine Paradise Environmental Fee | Ministry of Finance, Republic of Palau | A $100 departure fee on non-citizen visitors aged 13+, allocated by law among the sanctuary trust fund, states, airport, Green Fee and treasury.109 | Documented |
| Protected Areas Network Green Fee | PAN Fund and state governments | Part of the visitor fee finances 39 protected areas across all 16 states; the PAN Fund received more than $13 million in 2012–2019, covering about 58% of management needs.9 | Documented |
| Ol'au Palau | Palau Legacy Project with Host/Havas | Announced in 2022 as an app rewarding responsible visitor behaviour with access to places and experiences; we found no reported results.16 | Announced |
Challenges
- Repeated proposals since 2021 to reopen large parts of the marine sanctuary to commercial fishing, including a 2025 push to cut the no-take area to 50%.
- Conservation finance depends heavily on visitor arrivals, which collapsed during the pandemic.
- The IUCN rates tourism a high threat to the Rock Islands Southern Lagoon and describes its marine lakes as deteriorating.
- No independent evaluation of the Palau Pledge's effect on visitor behaviour or reef condition has been published.
Open questions
- What is the current legislative status (2026) of the proposal to reduce the sanctuary's no-take area?
- Has the study the president cited, finding a 50% no-take area optimal, been published, and has an independent study of the sanctuary been commissioned?
- Did the Cornell University work on measuring the pledge's effects produce published results?
- Is Ol'au Palau operating, and with what uptake?
