Singapore Unveils Sustainable Air Hub Blueprint for Aviation Decarbonization

166 Shares

Singapore's Minister for Transport, Chee Hong Tat, unveiled the Singapore Sustainable Air Hub Blueprint today, detailing a set of crucial actions aimed at decarbonizing Singapore’s aviation sector. Notable measures include new regulations mandating the use of sustainable aviation fuel (SAF) for all departing flights, starting at 1% from 2026, with plans for incremental increases in subsequent years.

Developed by the Civil Aviation Authority of Singapore (CAAS), the blueprint outlines strategies targeting airlines, airports, and air traffic management (ATM) to achieve objectives such as reducing domestic aviation emissions by 20% by 2030 and attaining net zero emissions by 2050.

Fuel constitutes the bulk of aviation emissions, making the adoption of SAF imperative. SAF, derived from sustainable sources like waste oils and agricultural residues, offers significant potential to slash greenhouse gas emissions by up to 85% compared to conventional fuels.

Despite its environmental benefits, widespread adoption of SAF faces obstacles such as limited supply and higher costs compared to traditional jet fuels. Currently, SAF accounts for less than 0.1% of jet fuel volumes.

CAAS projects that SAF will contribute substantially to achieving net zero emissions by 2050, with the blueprint mandating SAF usage for departing flights from 2026, starting at 1% and escalating to 3% - 5% by 2030, subject to global developments and increased availability.

To bolster the SAF ecosystem, the blueprint introduces initiatives like a SAF levy based on projected prices, centralized procurement, and investment in fleet renewal and operational enhancements.

In addition to SAF initiatives, the blueprint outlines efforts to reduce energy consumption and deploy renewable energy at airports, along with measures to optimize air traffic management operations for enhanced efficiency and reduced fuel consumption.

Enabling the implementation of these decarbonization initiatives are a series of enablers spanning policy, industry development, infrastructure planning, workforce transformation, and international partnerships. Singapore will also launch a S$50 million Aviation Sustainability Programme to support sustainable aviation projects.

Minister Chee Hong Tat emphasized Singapore's commitment to balancing aviation growth with environmental sustainability, envisioning a future where aviation thrives without compromising the environment. The blueprint, crafted through extensive consultation with stakeholders, is poised to catalyze sustainable aviation locally and globally.
