Q1With reference to the U.S. SAF Initiative, consider the following statements: 1. It is an interagency effort of the Department of Energy, Department of Transportation and Department of Agriculture. 2. It seeks to expand sustainable aviation fuel production and use through a government-wide memorandum of understanding. 3. It is led jointly by the Environmental Protection Agency, Federal Aviation Administration and Department of Commerce. Which of the statements given above are correct?
Statement 1 is correct because the cited fact identifies DOE, DOT and USDA as the interagency partners. Statement 2 is correct because the initiative expands SAF production and use through a government-wide memorandum of understanding. Statement 3 is wrong because the listed EPA, FAA and Commerce grouping is not the interagency set named in the fact.
Q2Assertion (A): India decided not to participate in the voluntary pilot and first phases of CORSIA. Reason (R): Offsetting requirements for Indian carriers under CORSIA start from 2024. Choose the correct answer.
The Assertion is true because India decided not to join CORSIA's voluntary pilot and first phases. The Reason is false because the offsetting requirements for Indian carriers start from 2027, not from 2024. Therefore the explanation based on a 2024 start date is not valid.
Q3With reference to Sustainable Aviation Fuel (SAF) in India, consider the following statements: 1. SAF is a renewable aviation-grade hydrocarbon fuel chemically similar to ATF and fully compatible with existing aircraft engines. 2. The Bureau of Indian Standards specification IS 17081 specifically covers SAF blended with traditional Aviation Turbine Fuel. 3. The mandatory phase of CORSIA, the global market-based measure for international aviation, begins in 2027. Which of the statements given above are correct?
All three statements are correct as per the PIB release of April 23, 2026 and BIS standards. SAF is a drop-in renewable hydrocarbon fuel chemically similar to ATF, IS 17081 specifically covers SAF blended with conventional ATF (IS 1571 covers petroleum-based ATF and co-processed SAF), and the mandatory phase of CORSIA implemented by ICAO begins in 2027 requiring offsetting of emissions above the baseline.
Q4Match the ReFuelEU Aviation SAF requirement milestones with their mandated shares at EU airports. List I 1. From 2025 2. From 2050 List II X. 2% of aviation fuel at EU airports Y. 70% at all EU airports Z. 10% of aviation fuel at EU airports W. 35% at all EU airports Select the correct matching.
The correct matching is from 2025 with 2% of aviation fuel at EU airports, and from 2050 with 70% at all EU airports. The 10% share is a near-miss from another mandate trajectory, not this ReFuelEU Aviation SAF milestone. The 35% figure relates to synthetic aviation fuel from 2050, not the overall SAF share tested here.
Q5As per India's indicative Sustainable Aviation Fuel blending targets in Aviation Turbine Fuel for international flights, which sequence is correct?
The cited PIB release gives the indicative blending targets for international flights as 1% in 2027, 2% in 2028 and 5% in 2030. The sequences beginning in 2026, jumping to 10% by 2030, or starting at 5% in 2027 do not match the stated target path.

6Match IATA's 2024 SAF share estimates with the correct production category. List I 1. Global jet fuel production 2. Global renewable fuel production List II X. 0.3% Y. 11% Which matching is correct?
7Arrange the phases of CORSIA in the correct chronological order.
8With reference to IATA's December 2024 estimate on sustainable aviation fuel production, consider the following statements: 1. SAF production was expected to reach 2.1 lakh tonnes in 2025. 2. The expected 2025 volume was stated as 2.7 billion litres. 3. The expected 2025 production was equal to 0.7% of total jet fuel production. Which of the statements given above are correct?
9Consider the following Assertion and Reason about ReFuelEU Aviation: Assertion: ReFuelEU Aviation sets a synthetic aviation fuel share of 35% from 2050 at all EU airports. Reason: It sets a synthetic aviation fuel share of 1.2% from 2030 at all EU airports. Select the correct answer.
10Which sequence correctly represents the ICAO Assembly action and the target year in the long-term global aspirational goal for international aviation?
11Consider the following statements about Sustainable Aviation Fuel in India: 1. SAF is a renewable aviation-grade hydrocarbon fuel chemically similar to ATF and compatible with existing aircraft engines. 2. BIS specification IS 1571 specifically covers SAF blended with traditional ATF, whereas IS 17081 covers only petroleum-based ATF. 3. India’s SAF blending targets are 1 percent by 2027, 2 percent by 2028 and 5 percent by 2030. 4. These SAF blending targets align with ICAO’s CORSIA; CORSIA’s mandatory phase begins in 2027. Which of the statements given above are correct?
12Match the ICAO cleaner-energy framework item with the vision stated for it. List I 1. Global Framework for SAF, LCAF and other Aviation Cleaner Energies List II a. Reduce CO2 emissions in international aviation by 5% by 2030 compared with zero cleaner-energy use b. Make all domestic aviation net-zero by 2040 compared with 2005 levels c. Reduce airport ground-emission inventories by 5% every year after 2030 d. Replace CORSIA offsetting with mandatory electric aircraft deployment by 2030
13Consider the following Assertion and Reason about CORSIA eligible fuels. Assertion: 14 June 2023 is a milestone date in ICAO's record of sustainable aviation fuel under CORSIA. Reason: ICAO records 14 June 2023 as the date when the first sustainable aviation fuel batches were certified under CORSIA. Choose the correct answer.
14Match the CORSIA baseline revision detail with its correct value. List I 1. ICAO General Assembly at which the baseline was revised 2. Revised CORSIA baseline List II a. 41st ICAO General Assembly b. 85% of 2019 emissions c. 40th ICAO General Assembly d. 100% of 2019 emissions
15IATA's December 2024 estimate described SAF production as doubling from 2023 to 2024. Which chronological sequence is correct?
