Consider the following statements: [Miscellaneous]

I. Carbon dioxide (CO₂) emissions in India are less than 0.5 t CO₂ / capita.

II. In terms of CO₂ emissions from fuel combustion, India ranks second in Asia-Pacific region.

III. Electricity and heat producers are the largest sources of CO₂ emissions in India.

Which of the statements given above is/are correct?

The correct option is II and III only.

Let us analyze each statement step-by-step to understand why this option is correct:

Statement I: Carbon dioxide (CO₂) emissions in India are less than 0.5 t CO₂ / capita.
This statement is incorrect. While India's per capita carbon dioxide emissions are significantly lower than the global average, they are not less than 0.5 tonnes (t) per capita. In recent years, India's per capita CO₂ emissions have hovered around 1.8 to 2.0 tonnes per capita, which is well above the 0.5 t CO₂ / capita mark mentioned in the statement.

Statement II: In terms of CO₂ emissions from fuel combustion, India ranks second in Asia-Pacific region.
This statement is correct. In the Asia-Pacific region, China is the largest emitter of CO₂ from fuel combustion due to its massive industrial base and population. India is the second-largest emitter in the region, followed by other countries like Japan and South Korea.

Statement III: Electricity and heat producers are the largest sources of CO₂ emissions in India.
This statement is correct. In India, the power sector (electricity and heat generation) relies heavily on fossil fuels, particularly coal. Coal-fired thermal power plants contribute the largest share of the country's total greenhouse gas and CO₂ emissions, making electricity and heat producers the dominant source of emissions, followed by industries and transport.

Since statements II and III are correct, the correct combination is II and III only.
