TRANSPORT AND CLIMATE PROFILE

Background

Palau, a high-income country in the Pacific Islands, has a small population of 18,000 and a GDP (PPP) of $310.8 million in 2024. Despite its wealth, with a GDP per capita of $17,563, it faces vulnerabilities common to Small Island Developing States (SIDS). Its economic and environmental challenges are increasingly influenced by the transport sector's impact and climate-related risks.

The transport sector is a major contributor to Palau's carbon emissions, producing 750 thousand tonnes of GHGs in 2024. This accounts for 49% of all economy-wide emissions, marking it as a key area for mitigation efforts. Before the Paris Agreement and SDGs, emissions from transport grew modestly—by 1.4% annually—but since 2015, emissions have increased at 2.3% per year.

Road transport is the primary pollution source, responsible for 88% of transport emissions and 43% of total GHG emissions. Domestic navigation and aviation contribute 7% and 5%, respectively. Notably, Palau's emissions intensity is high at 2413.0 gCO2e per USD of GDP in 2024, far exceeding the Asia-Pacific average of 29.0, the Pacific Islands average of 56.6, and the high-income economy benchmark of 34.1. While this intensity has decreased from a peak of 3899.2 in 2000, current levels still reveal a significant decoupling gap with regional and global peers.

In 2023, Palau's transport energy consumption reached 1,845 terajoules. While consumption growth has plateaued at <1% annually since 2010, the sector remains entirely dependent on fossil fuels. Oil products constitute 100% of the energy mix, a figure that has remained unchanged since 2010. Consequently, the penetration of biofuels and electricity in the transport energy balance stood at <1% in 2023.

The energy intensity of Palau's transport sector—5.94 megajoules (MJ) per USD of GDP in 2023—is notably higher than the Asia-Pacific (0.37 MJ) and Pacific Islands (0.74 MJ) averages. Interestingly, while road transport dominates emissions, it accounted for only 29% of transport energy consumption in 2023, while domestic navigation claimed the lion's share at 71%. This discrepancy suggests significant variations in fuel efficiency and carbon intensity across different modes of transit.

Palau's geography makes its transport infrastructure especially vulnerable to climate risks. Since 2000, the country has experienced four major natural disasters, with storms accounting for 75%, impacting 21,000 people. The economic impact is significant, with estimated average annual losses (AAL) to transport infrastructure at $179,300, about 0.058% of GDP. These losses mainly affect ports (47%), roads (33%), and airports (19%). The long-term outlook is becoming more concerning, as about 38% of Palau's population lives in low-elevation coastal zones at risk of sea-level rise. Additionally, under a 4.5°C rise in temperature, over 67% of the country's road and rail infrastructure could be exposed to more frequent and severe rainfall events. Currently, Palau ranks 184th out of 208 countries in the National Road Vulnerability Index, highlighting the urgent need to improve network redundancy and resilience capacity.

Motorization in Palau has risen significantly, from 325 vehicles per thousand people in 2000 to 751 in 2024, surpassing the Asia-Pacific average of 317. The vehicle fleet is varied, with 52% two-wheelers, 33% light-duty vehicles (LDVs), and 14% trucks. Despite increased investment in public transport—including the import of $4.2 million worth of buses from 2015 to 2024—the shift to electric mobility is still in its early stages infancy.

Between 2017 and 2024, EV imports reached $342 thousand, still making up less than 1% of total road vehicle imports as of 2024. UNEP's E-mobility Readiness Index scores Palau at 37 out of 100, with very low marks in policy (0) and financial instruments (8). Nonetheless, a new trend is emerging in the bus sector, where electric models accounted for 6.6% of trade from 2017 to 2024. Funding remains stable, with Official Development Assistance (ODA) totaling $36.2 million between 2011 and 2023. There has been a major shift in ODA focus: while road projects received 62% of funds from 2002 to 2010, they only received 3% from 2011 to 2023, as emphasis moved toward airport infrastructure (87%). No Public-Private Partnership (PPP) investments in transport have been recorded since 2000, reflecting reliance on public and donor funding for infrastructure. Palau has 16 transport-related policy documents, of which only three are climate-specific. The 2015 Nationally Determined Contribution (NDC) aims for a 22% reduction in energy sector emissions below 2005 levels by 2025. However, it lacks transport-specific GHG targets, a net-zero goal, or a Long-Term Strategy (LTS). Mitigation measures make up 73% of policies, compared to 32% for adaptation.

Avoid and Shift: To curb private vehicle reliance, Palau emphasizes developing a comprehensive public and active transport system. The Climate Change Policy calls for finalizing and launching a "Complete Street Policy" to improve traffic flow, reduce congestion, and support alternative transportation modes. This push for active mobility is supported by efforts led by the NGO PalauWalks, in collaboration with various government agencies, to create walk-friendly spaces, as outlined in the VNR Report 2024. Additionally, the National Energy Policy advocates for establishing energy-efficient public transport for urban and rural areas, particularly to lessen energy use for commuters heading to the Capitol. The VNR Report 2024 also features a Global Environmental Facility project that integrates electric and hybrid public transport vehicles, along with upgraded walking and biking infrastructure. In maritime transport, the Voluntary National Review 2019 - PLW envisions shifting to a domestic fleet powered by renewable energy sources such as sail, solar, and coconut oil, while the Development Plan 2023-2026 suggests replacing less efficient private vessels with larger, more efficient government-operated ships ship.

The technical modernization of Palau's vehicle and vessel fleets is a vital part of its climate strategy, emphasizing electrification and strict efficiency standards. The Palau Energy Act (Public Law No. 9-54 of 2014) requires efficiency standards for road and marine fleets, including buses and vessels in the private tourism sector. To promote this shift, the Climate Change Policy and National Energy Policy support legislation to introduce economic tools and import tax schemes that boost sales of energy-efficient vehicles and limit inefficient options. Electrification remains a top priority, with the Development Plan 2023-2026 proposing the deployment of upgraded EV charging stations—using solar PV and battery storage—to align daytime electricity use with solar energy. In maritime efforts, the Energy Efficiency Action Plan (EEAP) and the VNR Report 2024 focus on replacing inefficient two-stroke gasoline outboard engines with cleaner alternatives. Additionally, the Palau National Infrastructure Investment Plan 2021-2030 highlights the importance of climate-proofing low-lying roads and causeways, ensuring the resilience of the transport network against increasing climate impacts.
