Phase IFoundation

Background

Overview

CAFE norms are a critical policy tool for India to address climate change commitments (Glasgow), enhance energy security by reducing crude oil imports, manage macroeconomic stability (imported inflation, currency pressures), and promote industrial transformation towards low-carbon mobility.

Corporate Average Fuel Efficiency (CAFE) norms are regulations that set annual sales-weighted average fuel-efficiency targets for manufacturers’ passenger vehicle fleets. Introduced globally to reduce oil dependence and later to curb greenhouse gas emissions, they aim to drive innovation towards more fuel-efficient and low-emission vehicles.

Facts & tables

Key facts

Target Scope

Set fleet-wide average targets for manufacturers, not individual model targets.

Primary Objectives

Initially to reduce oil dependence and consumer costs; later expanded to reduce greenhouse gas emissions.

India's CAFE III Target

Aims to reduce average emissions from ~113 gCO2/km to 77 gCO2/km by FY2031-32.

Global Precedent

First introduced in the United States in 1975; China adopted mandatory standards in 2004.

Flexibility Mechanisms in India's CAFE III

MechanismImpact on Stringency
Carbon Neutrality FactorAwards compliance benefits for vehicles compatible with higher ethanol blends, despite policy uncertainty.
Super CreditsGives additional weight to EVs, plug-in hybrids, strong hybrids, and flex-fuel vehicles, reducing actual low-emission sales needed.
Banking & Trading of CreditsAllows companies to buy/sell credits, or purchase from BEE, potentially delaying technology upgrades.
Multi-year Compliance BlocksAllows averaging performance over 2-3 years, permitting delays in meeting annual targets.

Quick revision

  • Fleet-wide average fuel efficiency targets for passenger vehicles.
  • Dual objectives: energy security (oil dependence) and climate change (GHG emissions).
  • India's CAFE III includes Carbon Neutrality Factor, Super Credits, Banking/Trading.
  • BEE acts as administrator and seller of last resort for compliance credits.
  • Crucial for India's Glasgow commitments and macroeconomic stability.
