3. CAFE NORMS (Syllabus: GS Paper 3 – Env & Eco)

Context: In a move designed to contribute to India’s ambitious climate targets and lower carbon emissions, the central government is planning to introduce the next stage of norms for fuel economy or efficiency of automobiles.

Corporate Average Fuel Economy

• About: CAFE stands for Corporate Average Fuel Efficiency/Economy, focusing on the weighted average of emissions and economy for the entire fleet.

oBS6, however, targets specific emissions like hydrocarbons, sulfur, and NOx.

Purpose of CAFE regulations:

• The CAFE (Corporate Average Fuel Efficiency) regulations aim to reduce the overall COx (Carbon Oxides) from the vehicle’s exhaust.
• The reduced carbon footprint leads to increased fuel economy.
• These regulations were first implemented on 1st April 2017 with BS4 exhaust emission norms.
• It was decided the highest carbon footprint allowed was 130gm per km till 2022. After that, the till will be further reduced to 113gm per km.
• CAFE regulations are in power for all engines. Diesel, Petrol, as well as CNG.

Coral Bleaching

• About: When corals are stressed by changes in conditions such as temperature, light, or nutrients, they expel the symbiotic algae microscopic algae called zooxanthellae living in their tissues, causing them to turn completely white.
• Causes: 
• Temperature Sensitivity: A mere one-degree Celsius increase in temperature over a four-week period can trigger coral bleaching events.
• Transparency and Skeleton Exposure: Bleached corals become transparent, exposing their white skeletons as a result of expelling algae.

9. SHRINKFLATION (Syllabus: GS Paper 3 – Economy)

Context: As input prices, which were benign for a few quarters, turn inflationary, the spectre of shrinking packs looms large within the fast-moving consumer goods (FMCG) segment.

Shrinkflation

• About: It occurs when goods decrease in size while maintaining the same price, effectively reducing the value consumers receive.
• Hidden Inflation: It's a form of concealed inflation where producers opt to shrink product sizes rather than directly increasing prices.
• Price Dynamics: Although the absolute price remains constant, the price per unit of weight or volume rises due to the reduced size of the product.
• Reasons Behind Shrinkflation: Rising production costs and market competition are the primary drivers of shrinkflation.
• Higher Production Costs: Increased costs of ingredients, raw materials, energy, and labor prompt manufacturers to downsize products to maintain profit margins.
• Causes of Shrinkflation:

oIncreased Costs: Higher expenses in production lead to companies reducing product sizes to maintain profitability.

oIntense Market Competition: Pressure to keep prices competitive drives companies to shrink product sizes rather than increase prices.

oChanging Customer Demands: Evolving preferences may prompt companies to alter product formulations, resulting in size adjustments to meet demand.

• Impacts of Shrinkflation:

o Shrinkflation risks alienating customers who perceive they're receiving less for the same price.

o It complicates measuring price changes and inflation accurately, as product sizes may vary without reflecting in the price point.
