Connect with the basics –

Direct Tax

• A direct tax is paid straight to the government by the person or business that earns the income or profit.
• The burden of this tax cannot be shifted to anyone else; you are solely responsible for paying it.
• Governing Body: Central Board of Direct Taxes (CBDT).

Key Examples:

• Income Tax: Paid by individuals on their annual earnings.
• Corporate Tax: Paid by companies on their yearly profits.
• Capital Gains Tax: Levied on profits from selling assets like property or stocks.
• Securities Transaction Tax (STT): Charged on the sale and purchase of securities on stock exchanges.

Indirect Tax

• An indirect tax is levied on the consumption of goods and services.
• Unlike direct taxes, the burden is transferable; a shopkeeper pays the tax to the government but recovers that cost from you through the selling price.
• Governing Body: Central Board of Indirect Taxes and Customs (CBIC).

Key Examples:

• Goods and Services Tax (GST): The primary indirect tax in India that replaced multiple older taxes like VAT and service tax.
• Customs Duty: Imposed on goods imported into or exported out of India.
• Excise Duty: Still applicable to limited items like petroleum products and alcohol

E20 Petrol

• Target Advancement: The initial target for 20% blending was 2030, but it was advanced to 2025–26 under the amended National Policy on Biofuels (2022).

Significance for India

India’s Push for Piped Natural Gas

Science and Tech

Context

• India is accelerating the expansion of Piped Natural Gas (PNG) connections to reduce import dependence, improve energy security, and transition towards a cleaner fuel mix.

Types of Gases

Liquefied Petroleum Gas (LPG):

• Composition: Propane and Butane.
• State & Storage: Stored as a liquid under moderate pressure in cylinders.
• Usage: Domestic cooking, water heating, and small-scale industrial applications.
• Key Characteristic: Heavier than air; collects on the ground if leaked.

Piped Natural Gas (PNG):

• Composition: Primarily Methane.
• State & Storage: Delivered as a gas through underground pipelines.
• Usage: Residential kitchens, commercial cooking, and industries.
• Key Characteristic: Continuous supply; no need for cylinder storage.

Compressed Natural Gas (CNG):

• Composition: Primarily Methane.
• State & Storage: Compressed to high pressure (200-250 bar) in tanks.
• Usage: Vehicles (cars, buses, autos) and low-pressure industrial burners.
• Key Characteristic: Cleaner burning than petrol/diesel.

Liquefied Natural Gas (LNG):

• Composition: Primarily Methane.
• State & Storage: Cooled to roughly –160°C to become a liquid for transport.
• Usage: Transporting natural gas over long distances by sea, power generation.
• Key Characteristic: Volume is reduced by 600 times, making it easy to store in bulk.

India’s Shift Towards Piped Natural Gas (PNG)

• Reducing Import Dependence: India imports nearly 60% of its LPG requirement, with a large share coming from West Asia and supply routes like Strait of Hormuz are geopolitically vulnerable.
• Economic Efficiency: PNG eliminates logistics costs associated with cylinder transportation and storage.
• Pricing can be more stable compared to LPG, which is sensitive to global oil prices.
• Environmental Benefits: Natural gas burns cleaner than LPG, producing fewer pollutants and greenhouse gases.
