2. CCI Overhauls Cost Regulations to Tackle Predatory Pricing in Digital Markets

Context: In a significant regulatory shift, the Competition Commission of India (CCI) has issued the “Determination of Cost of Production Regulations, 2025”, replacing the older 2009 framework. This new regulation marks a critical update in India’s antitrust oversight, specifically targeting predatory pricing and deep discounting, particularly in e-commerce and quick-commerce sectors.

Understanding the Context: Predatory Pricing and Market Fairness

Predatory pricing refers to the strategy of selling goods or services at prices below production cost with the intent to undermine competition or drive rivals out of the market. Under Section 4 of the Competition Act, 2002, such conduct is considered an abuse of dominant position and is subject to strict scrutiny by the CCI.

The now-superseded Cost Regulations, 2009, were developed in a pre-digital era and struggled to address the complex economics of modern, platform-based markets, where cross-subsidies, free services, and non-cash value have become common.

Highlights of the 2025 Cost Determination Framework:

1. Adaptive and Sector-Neutral Design:

• Moves away from the rigid one-size-fits-all structure.
• Allows case-specific evaluations, recognizing the distinct dynamics of digital, retail, telecom, and tech-driven platforms.

2. Focus on Internal Production Cost:

• Establishes internal cost of production as the benchmark for pricing analysis.
• Rejects the use of market value as a benchmark due to its reliance on consumer perceptions, subsidies, or branding, which may not reflect actual cost.

3. Aligned with Global Best Practices:

• Incorporates insights from international competition authorities and modern economic theory.
• Builds on evolving jurisprudence on platform economies, network effects, and dynamic pricing models.

4. Clear Framework for Evidence-Based Investigations:

• Offers the CCI a standardized yet flexible approach to assess pricing practices.
• Enables deeper scrutiny of pricing algorithms, subscription bundles, and freemium models.

Why This Matters: Implications for India’s Competition Ecosystem

Legal and Regulatory Clarity:

• The 2025 regulations provide a more objective and economically sound method to determine cost benchmarks.
• Enhances legal certainty for firms operating in highly competitive and tech-driven sectors.

Digital Economy Focus:

• The framework explicitly considers cross-subsidization, high fixed costs, and non-linear pricing strategies—hallmarks of startups and digital giants.
• Enables CCI to effectively assess zero-price markets, like those offering free apps or services.

Level Playing Field for MSMEs:

• Protects Micro, Small, and Medium Enterprises (MSMEs) from being priced out by loss-leading strategies of dominant players.
• Encourages fair competition and innovation by ensuring market access for smaller businesses.

Better Enforcement Capacity:

• Empowers CCI to conduct more precise, consistent, and data-driven investigations into alleged anti-competitive pricing.
• Strengthens India’s regulatory readiness in the face of rapidly evolving digital business models.

Global Context and Comparative Insight:

• European Union and United States regulators have also faced similar challenges in defining cost metrics in platform economies.
• Countries like Australia and Japan have adopted dynamic tools to regulate pricing in sectors such as ride-sharing, e-retail, and online food delivery.
• India’s 2025 regulation brings it in line with mature jurisdictions, reinforcing its role as a progressive antitrust authority in the Global South.

Conclusion:

The 2025 Cost of Production Regulations represent a forward-looking approach to maintaining fair competition in a rapidly digitizing economy. By modernizing its toolkit, the CCI is better equipped to curb exploitative practices, preserve consumer welfare, and protect India’s competitive digital landscape from monopolistic abuse.

3. Invisible Scars: The Growing Threat of Gully Erosion

Context: A recent study published in Scientific Reports warns that gully erosion, a severe form of land degradation, poses a direct threat to the achievement of at least nine out of the 17 Sustainable Development Goals (SDGs). It particularly endangers efforts related to Zero Hunger (SDG 2), Clean Water and Sanitation (SDG 6), and Climate Action (SDG 13). Despite its devastating impact, this form of erosion remains largely invisible in mainstream environmental policy and discourse.

What is Gully Erosion?

Gully erosion occurs when runoff water aggressively cuts through the soil, creating deep, narrow channels (gullies) in the landscape. These gullies grow in size over time, often turning into ravines that can stretch for kilometers.

What makes gully erosion especially dangerous is its:

• Depth and speed of land degradation
• Unpredictable progression
• Extremely high soil loss per unit area, surpassing other erosion types

Unlike sheet or rill erosion, gully erosion is difficult to reverse and leaves permanent scars on the land.

The Global and Indian Landscape:

Worldwide Impact:

• 51 countries have reported disasters directly linked to gully formation.
• Nigeria stands out, with 15 major locations severely affected by this hazard.

India’s Erosion Hotspots:

• Gully-affected areas span across 19 states and the National Capital Territory of Delhi.
• Severely impacted states: Jharkhand, Chhattisgarh, Madhya Pradesh, and Rajasthan.
• In regions like Bundelkhand, expanding gullies are turning once-arable land into barren badlands.

What Drives Gully Erosion?

1. Loss of Vegetation Cover:

• Tree felling and degradation of grasslands weaken soil structure.
• Without plant roots to bind the soil, intense rainstorms quickly carve gullies.

2. Erratic Weather Patterns:

• Prolonged droughts followed by heavy downpours create ideal conditions for runoff-induced erosion.
• Climate change is amplifying this cycle, particularly in semi-arid and sub-humid regions.

3. Poor Waste Management:

• Dumping of solid waste into natural drainage channels causes blockages, diverting water flow and creating high-pressure zones that deepen gullies.

4. Fragile Soil Types:

• Regions with sandy, loose, or lateritic soils, like those in Chhattisgarh and Jharkhand, are especially prone to erosion under water pressure.

The Devastating Impacts:

1. Loss of Fertile Topsoil:

• The topmost layer of soil, rich in nutrients, is washed away—crippling agricultural productivity.
• Once lost, it may take hundreds of years to regenerate, threatening food security and farmer livelihoods.

2. Water Scarcity and Drought:

• Erosion reduces groundwater recharge and increases surface runoff, worsening water shortages and disrupting local hydrological cycles.

3. Ecological Damage:

• Gullies fragment habitats, reducing biodiversity and disturbing native flora and fauna.
• Leads to decline in pollinator species and the spread of invasive plants in degraded lands.

4. Sediment Overload in Rivers:

• Displaced soil ends up clogging rivers, lakes, and reservoirs, leading to siltation, reduced water storage, and flooding risks downstream.

The Way Forward: Strategies for Resilience:

1. Reforestation and Vegetative Barriers:

• Planting native species in erosion-prone catchments helps stabilize soil and reduce runoff.
• Vetiver grass, with its deep root system, has proven highly effective in controlling gully spread.

2. Sustainable Land Use Practices:

• Promote terracing, agroforestry, contour bunding, and cover cropping to adapt land management to terrain and soil characteristics.

3. Structural Interventions:

• Constructing check dams, gabion walls, and gully plugs helps to slow down water flow, allowing sediment deposition and soil recovery.

4. Community Involvement and Education:

• Involving local communities, especially tribal and farming populations, in watershed management enhances long-term impact.
• Awareness programs about the economic and ecological costs of gully erosion can change local land-use behavior.

A National Call to Action:

India has pledged to restore 26 million hectares of degraded land by 2030 under its commitment to the United Nations Convention to Combat Desertification (UNCCD). Addressing gully erosion must become a central pillar of this restoration mission.This land degradation challenge is invisible only until it is irreversible. By integrating both preventive and restorative approaches, India can not only protect its landscapes but also secure food, water, and livelihoods for future generations.

5. Methane: The Silent Accelerator of Global Warming

Context: According to the International Energy Agency’s (IEA) Global Methane Tracker 2025, the global energy sector released around 145 million tonnes (Mt) of methane in 2024. Of this, oil and gas facilities alone contributed over 80 Mt, making them the largest culprits in energy-related methane emissions.

What is Methane?

Methane (CH₄) is a colourless, odourless, and highly flammable gas, commonly referred to as marsh gas. Although it stays in the atmosphere for only about 10 years, it is over 80 times more potent than carbon dioxide (CO₂) in terms of global warming potential (GWP) over a 20-year period.

Key Characteristics:

• Short atmospheric lifespan: ~10 years
• Global Warming Potential: ~80x more than CO₂ (over 20 years)
• Primary sources: ~60% from human activity, ~40% from natural sources like wetlands, permafrost thawing, and volcanic activity

Anthropogenic Sources of Methane Emissions:

1. Energy Sector – A Leading Contributor:

The energy industry accounts for over 35% of human-induced methane emissions, making it the largest industrial source.

Breakdown within the Energy Sector:

• Oil production: ~45 Mt
• Natural gas operations: ~35 Mt
• Coal mining activities: Over 40 Mt, including 4 Mt from abandoned mines
• Abandoned oil & gas wells: ~3 Mt
• Bioenergy (traditional biomass): ~18 Mt — largely from wood, dung, and charcoal in developing countries
• Modern bioenergy (like biogas, biofuels, and biomethane): ~2 Mt
• End-use equipment leakage: Contributes an extra ~2 Mt

2. Agriculture – Livestock and Rice Cultivation:

Agriculture is another major emitter of methane, primarily through:

• Enteric fermentation in livestock (especially cattle)
• Manure management
• Flooded rice fields, which produce methane due to anaerobic conditions

India and China are among the top agricultural methane emitters, given their large livestock populations and extensive rice cultivation.

3. Waste Sector – Landfills and Wastewater:

• Organic waste in landfills and wastewater treatment plants decomposes anaerobically, emitting significant amounts of methane.

Methane’s Role in Climate Change:

Methane is responsible for nearly 30% of global warming since the Industrial Revolution. Its atmospheric concentration is now 2.5 times higher than pre-industrial levels and continues to increase at an alarming rate.

Studies show that methane concentrations are rising faster than any other greenhouse gas, underscoring its critical role in near-term climate action.

Tackling the Methane Challenge:

Mitigation Potential:

The IEA emphasizes that:

• ~70% of fossil fuel-related methane emissions can be prevented using existing technologies.
• In the oil and gas sector, ~75% of emissions could be cut by fixing leaks, improving infrastructure, and plugging abandoned wells.

Top Emitters from Fossil Fuels:

• China
• United States
• Russia
• Iran
• Turkmenistan
• India

Global Response:

• Global Methane Pledge: Over 150 countries, including India, have committed to collectively reduce methane emissions by 30% by 2030, relative to 2020 levels.
• Technological Interventions: Satellites like GHGSat and Copernicus Sentinel-5P are now being used to track methane hotspots and support enforcement efforts.

Conclusion: Urgency for Action

Methane may be invisible, but its impact on our climate is immense. With its high warming potential and short lifespan, cutting methane is one of the fastest and most cost-effective ways to slow down global warming in the near term.

To meet global climate goals, particularly the 1.5°C target of the Paris Agreement, governments, industries, and communities must act swiftly to monitor, regulate, and reduce methane emissions across sectors.
