Syllabus: GS3/ Energy
Context
- The Ministry of Coal has notified the Coal Exchange Rules, 2026, paving the way for the establishment of Coal Exchanges in the country to enable transparent and market-driven coal trading.
What is a Coal Exchange?
- A Coal Exchange is an electronic marketplace where coal producers, consumers, traders, and other participants can buy and sell coal through transparent trading mechanisms.
- It facilitates efficient price discovery based on market demand and supply conditions.
Key Features of the Coal Exchange Rules, 2026
- Market-Based Trading: The framework shifts coal marketing from the traditional one-to-many model (producer to multiple consumers) to a many-to-many trading model.
- Price Discovery: Coal prices will be determined through market forces rather than administrative allocations.
- Regulatory Oversight: The Coal Controller Organisation (CCO) is the nodal authority tasked with registering and overseeing these exchanges.
- Exchange Registration: Entities operating an exchange must be incorporated as a company in India with a minimum net worth of ₹50 crore. Registrations are granted for 25 years.
- Transition Timeline: Pre-existing electronic coal trading platforms must transition and register as a Coal Exchange within six months of the first registered exchange’s commencement.
- Demutualization: The ownership and management do not hold any trading rights in the exchange.
Coal Sector in India
- India is the world’s second-largest producer and consumer of coal. India has the fifth-largest coal reserves globally.
- Coal accounts for around 55% of India’s primary commercial energy requirement and about 70% of electricity generation.
- Major coal-producing regions are concentrated in states such as Odisha, Jharkhand, Chhattisgarh, Madhya Pradesh, and West Bengal

Syllabus: GS3/Science and Technology
Context
- According to a report, Indian consumers are losing an estimated ₹25,000 crore to ₹28,000 crore annually due to dark patterns, across online marketplaces.

New Rule Requires Fish Survival Test for Caustic Soda Industry Wastewater
Syllabus: GS3/Environment
Context
- Wastewater from caustic soda plants using membrane cell technology will now have to pass a laboratory-based fish survival test under new environmental standards notified by the Union government.
About
- The new standards apply to standalone caustic soda plants that use membrane cell technology.
- Membrane cell technology uses a special membrane to control the chemical process and is considered less polluting than older mercury-based processes.
- The rules say at least 90% of fish must survive after 96 hours in 100% wastewater during laboratory-based bioassay testing.
- The standards also set limits for pH, chloride, suspended solids, dissolved solids, water use and wastewater generation.
- Experts say enforcement will be key, as bioassay testing requires specialised laboratories, trained staff and regular independent monitoring.
Caustic soda
- Caustic soda, also known as sodium hydroxide, is one of India’s most widely used industrial chemicals.
- It is used in industries such as soap, detergents, paper, textiles, aluminium, petrochemicals and water purification.
- India has about 32 to 37 caustic soda plants, with annual production of more than five million metric tonnes.
- But the industry can also pose environmental risks because its wastewater is often highly alkaline and saline. It may contain chlorine, hydrochloric acid and high levels of dissolved solids.
