India’s New CAFE-III Fuel Efficiency Norms

Why in News?

• The government has notified the Corporate Average Fuel Economy (CAFE)-III norms, which will apply from April 1, 2027, to March 31, 2032. 
• The rules aim to improve fuel efficiency and reduce carbon dioxide (CO₂) emissions from passenger vehicles. 

Key Features

• Manufacturers will be assessed on the average fuel consumption of all eligible vehicles sold, rather than each model separately. 
• The permitted fuel consumption will depend on the manufacturer’s average vehicle weight. Heavier fleets will have a higher permissible fuel-consumption limit. 
• The efficiency targets will become progressively stricter between FY2027-28 and FY2031-32. 
• The final rules do not provide a separate 3 g/km benefit to petrol cars weighing below 909 kg. However, vehicle weight remains an important part of the overall formula. 
• EV advantage: Battery-electric vehicles (BEVs) and range-extended EVs receive a volume factor of 3, meaning their sales are counted as three times the actual volume for compliance calculations. 
• Hybrid vehicles: Plug-in hybrids and other strong hybrids also receive additional compliance benefits. 
• Alternative fuels: The framework recognises cleaner fuels such as ethanol-blended petrol, biofuels and compressed biogas (CBG) through a Carbon Neutrality Factor. 
• Compliance mechanism: Manufacturers can earn credits by performing better than their targets and use or trade these credits to meet future requirements. 
• Technology incentives: Features such as start-stop systems, regenerative braking, tyre-pressure monitoring and efficient air-conditioning can provide additional efficiency benefits, subject to a limit. 

Significance

• CAFE-III is expected to encourage fuel-efficient vehicles, electrification, hybrid technology and cleaner fuels. 
• It also gives automobile manufacturers greater flexibility to meet emission targets through different technologies. 

About Corporate Average Fuel Efficiency (CAFE) Norms

• CAFE norms are government rules that set fuel-efficiency and CO₂ emission targets for automobile manufacturers. 
• They apply to the average performance of a manufacturer’s entire fleet, not to individual vehicles. 
• Key objectives: 
  • Reduce fuel consumption. 
  • Lower CO₂ and other greenhouse gas emissions. 
  • Reduce dependence on crude oil imports. 
  • Promote cleaner and energy-efficient mobility. 
• Manufacturers must maintain a prescribed average CO₂ emission limit (g/km) across eligible vehicles. 
• Compliance is assessed using standard vehicle testing procedures such as the Modified Indian Driving Cycle (MIDC). 
• CAFE-I: Introduced in 2017. 
• CAFE-II: Came into effect from 2022 with stricter efficiency and emission requirements. 
• CAFE-III: Scheduled to apply from April 2027, with tighter standards and greater emphasis on cleaner technologies. 
• The system allows manufacturers to balance less-efficient vehicles with fuel-efficient, hybrid and electric vehicles. 
• CAFE norms are implemented by the Ministry of Power under the Energy Conservation Act, 2001. 
• The norms support India’s broader climate goals, including its net-zero emissions target for 2070.

Practice Question 

Consider the following statements regarding India’s Corporate Average Fuel Economy (CAFE)-III norms:

1. CAFE-III assesses manufacturers on the basis of the average fuel consumption of their eligible vehicle fleet rather than the performance of individual models. 
2. Battery-electric vehicles and range-extended electric vehicles receive a volume factor of 3 for compliance calculations. 
3. Petrol cars weighing below 909 kg receive a separate benefit of 3 g/km under the final CAFE-III framework. 
4. Manufacturers can use or trade credits earned through better-than-target fleet performance to meet compliance requirements. 

Which of the statements given above are correct?

(a) 1 and 2 only
(b) 1, 2 and 4 only
(c) 2, 3 and 4 only
(d) 1, 2, 3 and 4

Answer: (b) 1, 2 and 4 only

Explanation:

• CAFE-III evaluates manufacturers based on the average fuel consumption of their eligible vehicle fleet, rather than requiring every individual model to meet the same target. Hence Statement 1 is correct.
• Battery-electric vehicles (BEVs) and range-extended EVs receive a volume factor of 3, so their sales are counted at three times their actual volume for compliance calculations. Hence, Statement 2 is correct.
• The final CAFE-III rules do not provide a separate 3 g/km benefit to petrol cars weighing below 909 kg. Vehicle weight, however, remains part of the overall formula. Hence, Statement 3 is incorrect.
• Manufacturers that perform better than their prescribed targets can earn credits, which can be carried forward or traded to help meet compliance requirements. Hence, Statement 4 is correct.
