TRANSPORT AND CLIMATE PROFILE

Background

Timor-Leste, a low and lower-middle-income economy in the Southeast Asia region, presents a unique developmental profile with a population of 1.4 million and a GDP (PPP) of $6.7 billion as of 2024. The nation's transport sector is a critical component of its economic framework, yet it faces significant challenges regarding decarbonization and climate resilience. In 2024, the transport sector contributed 322 thousand tonnes of greenhouse gas (GHG) emissions, accounting for approximately 17% of total economy-wide emissions. While the sector's CO2 emissions grew at an annual rate of 10.9% prior to the adoption of the Paris Agreement and Sustainable Development Goals, this growth has decelerated to 3.9% annually since 2015, reflecting a shifting, albeit still upward, emissions trajectory.

The emissions profile of Timor-Leste is heavily dominated by road transport, which represents 86% of total transport emissions and 14% of the nation's total GHG output. In contrast, domestic navigation and domestic aviation contribute 7% each, while rail remains nonexistent. Notably, the carbon intensity of the transport sector—measured at 48.4 gCO2e per USD of GDP in 2024—remains significantly higher than the Asia-Pacific average (29.0 gCO2e) and the Southeast Asian subregional average (34.3 gCO2e). Although this intensity has improved from the 61.1 gCO2e recorded in 2015, it remains above the 2000 levels, suggesting that decoupling transport emissions from economic growth remains an elusive goal.

Energy consumption patterns further underscore the sector's reliance on fossil fuels. In 2023, transport energy consumption reached 2,133 terajoules, with the road sector accounting for 100% of this demand. Dependency on oil products has remained absolute at 100% since 2010, with biofuels and electricity recording minimal shares (<1%) in the energy mix. The energy intensity of 0.32 megajoules per USD is notably higher than the average for low and lower-middle-income economies (0.24 MJ/USD), coupled with the lack of diversification into renewable energy sources poses a long-term risk to energy security and climate mitigation efforts.

Timor-Leste's geographic and socio-economic vulnerabilities are exacerbated by the increasing frequency of natural disasters. Since 2000, the country has recorded ten major disasters—primarily flooding (50%) and storms (20%)—affecting 286,000 people and resulting in substantial economic losses. The transport sector is particularly exposed, with potential average annual losses to infrastructure estimated at $3.6 million, or 0.055% of GDP. Roads bear 94% of these projected losses. Furthermore, the country ranks 117th globally in National Road Vulnerability, and under a 4.5-degree warming scenario, over 3% of transport assets could be exposed to extreme precipitation, while 1% of the population in low-lying coastal zones faces threats from sea-level rise.

On the demand side, motorization rates have climbed to 300 vehicles per thousand population in 2024. The vehicle fleet is characterized by a high proportion of light-duty vehicles (56%) and two-wheelers (42%), with a conspicuous absence of buses and trucks in the modal split. Efforts to modernize the fleet are visible in the $10 million spent on bus imports between 2015 and 2024; however, <1% of this trade involved electric vehicles. While electric vehicle (EV) imports reached $2 million by 2024—comprising 1% of total road vehicle imports—the country's e-mobility readiness remains low. With a UNEP E-mobility Readiness Index score of 40, Timor-Leste suffers from a total lack of specialized policy (scoring 0) and weak financial instruments (scoring 11), despite some progress in energy and technology readiness.

Infrastructure development and public service delivery remain significant bottlenecks. In Timor-Leste's urban agglomerations, 80% of residents lack convenient access to public transport. Financial flows into the sector have increased substantially, with Official Development Assistance (ODA) rising from $50.7 million (2002-2010) to $406.7 million (2011-2023), shifting heavily toward road projects. Public-Private Partnerships (PPP) also emerged in the latter period, totaling $490 million, though these were exclusively directed toward port infrastructure.

The strategic policy landscape is governed by several primary documents, including the Updated 2022 NDC. However, the current policy framework lacks specific economy-wide GHG targets, net-zero commitments, or transport-specific emissions targets. While 72% of policy measures relate to climate mitigation, only 52% address adaptation and resilience. Priority actions are currently focused on disaster early warning systems, road expansion, and vehicle import restrictions. Bridging the gap between high-level strategic documents like the Strategic Development Plan 2011-2030 and actionable, climate-aligned transport investments will be essential for Timor-Leste to navigate its transition toward a sustainable and resilient transport future.

Timor-Leste's transport policy is currently evolving from a focus on post-conflict rebuilding to one emphasizing low-carbon development and climate resilience. The main instrument guiding this transition is the National Policy for Climate Change (Government Resolution 8/2022), which addresses both reducing greenhouse gas (GHG) emissions through fleet improvements and promoting public transportation in urban and rural areas. This approach is embedded in the Timor-Leste Updated NDC 2022-2030, linking climate risk management with sectoral planning to support environmentally sustainable development. A key initiative is the creation of a transport master plan, aimed at fostering climate-friendly mobility options and enhancing sector resilience against hydro-meteorological hazards.

In the "Avoid" domain, the government focuses on decoupling transport demand from economic growth through integrated land-use planning and strategic infrastructure prioritization. The Timor-Leste Updated NDC 2022-2030 highlights the implementation of land-use planning and environmental licensing regimes as critical tools to minimize exposure to climate risks. This is supported by the Transport Sector Master Plan, which emphasizes the need for broad cooperation among stakeholders to balance traffic, transport, and development needs, thereby managing urban congestion through planned growth rather than reactive expansion. Furthermore, the Timor-Leste Strategic Development Plan 2011-2030 establishes a rigorous standard for network growth, stipulating that new roads will only be constructed if they fulfill essential economic or social objectives, effectively prioritizing the optimization of the existing network over unnecessary footprint expansion.

The "Shift" strategy emphasizes a modal transition toward public transport and non-motorized solutions to reduce the carbon intensity of passenger travel. The Second National Communication - TLS and the Transport Sector Master Plan advocate for the provision of dedicated pedestrian and bicycle lanes to encourage active mobility. To modernize public transport, the Transport Sector Master Plan outlines major investments, including the construction of the new Dili Central Bus Terminal and the introduction of hybrid scheduled and demand services to improve city-municipality linkages. These infrastructure developments are reinforced by the Intended Nationally Determined Contributions - TLS, which prioritizes the establishment of necessary regulations and facilities, such as proper bus stops and terminals, to ensure that public transport becomes a convenient and reliable alternative to private vehicle use.

Finally, the "Improve" measures focus on enhancing the technical efficiency of the vehicle fleet and facilitating the shift to cleaner energy sources. Regulation No. 1/2015 of 2015, which amends Regulation No. 1 of 2014 on Fuel, Biofuel, and Lubricant Quality Standards, governs the domestic market by aiming to reduce pollutant emissions and allows biofuel blending up to 20%. To maintain a modern and efficient fleet, Decree-Law No. 30/2011 of 2011 sets conditions and procedures for importing motor vehicles, specifically prohibiting the import of light passenger vehicles older than five years— a standard that the Timor-Leste Updated NDC 2022-2030 plans to uphold and update as necessary. In the aviation sector, the Transport Sector Master Plan highlights the implementation of advanced satellite-based navigation and Automatic Dependent Surveillance-Broadcasting (ADS-B) systems to improve safety and fuel efficiency at the country's airports.
