Answer: (C) II and III only

Let's check each statement about India's carbon emissions:

(I) 'CO₂ emissions in India are less than 0.5 t CO₂/capita' — INCORRECT.

India's per capita CO₂ emissions are approximately 1.9-2.0 tonnes per year (as of recent data).

While this is much lower than countries like the US (~15 t/capita) or China (~8 t/capita), it is still far above 0.5 tonnes.

The statement significantly understates India's per capita emissions. ✗

(II) 'India ranks second in Asia-Pacific in CO₂ emissions from fuel combustion' — CORRECT.

China is the largest emitter in the Asia-Pacific region (and globally), and India is the second largest.

India surpassed Japan to take this position.

Overall globally, India is the third-largest CO₂ emitter after China and the US. ✓

(III) 'Electricity and heat producers are the largest source of CO₂ emissions in India' — CORRECT.

India's power sector (electricity generation and heat production) is the single largest source of CO₂ emissions, primarily because India still relies heavily on coal-fired thermal power plants for about 70% of its electricity generation. ✓

Statements II and III are correct. Answer is (c).

Why this was asked

India is the world's third-largest CO₂ emitter after China and the US, but its per capita emissions are around 2 tonnes, much lower than developed countries.

Coal-fired thermal power plants generate about 70% of India's electricity, making the power sector the largest source of CO₂ emissions in the country.

The question tests whether students can distinguish between total emissions rankings versus per capita emissions data for India.

India's CO₂ Emissions: Per Capita, Global Ranking & Sectoral Breakdown

Must know

India's per capita CO₂ emissions are approximately 1.9-2.0 tonnes/year, not below 0.5 tonnes

India ranks 3rd globally and 2nd in Asia-Pacific for total CO₂ emissions from fuel combustion

Electricity and heat production is India's largest CO₂ emission source due to coal dependence

Good to know

India's emissions are still much lower per capita than developed countries like US (15 t) or China (8 t)

Context

India's CO₂ emission profile reflects its status as a developing economy with large population but relatively lower energy consumption per person. Understanding both total emissions and per capita figures is crucial for climate policy discussions.

Question Analysis

This question tested knowledge of India's emission statistics. Statement I was a trap with an unrealistically low per capita figure (0.5 t vs actual 1.9-2.0 t). Statements II and III correctly identified India's regional ranking and dominant emission source.

Exam traps

Trap: Statement I gives 0.5 t CO₂/capita - actual figure is 1.9-2.0 tonnes, nearly 4 times higher

Don't confuse India's low per capita emissions with high total emissions due to large population

India is 3rd globally but 2nd in Asia-Pacific - regional vs global rankings differ

Electricity sector dominates because 70% power from coal, not because of total energy use

Don't confuse total emissions (India 3rd globally) with per capita (India much lower)

Japan is now 3rd in Asia-Pacific, having been overtaken by India

India's Power Sector Emissions

Environment electricity heat producers largest source

India's Power Sector: Largest CO₂ Source Due to Coal Dependence

Must know

Electricity and heat production accounts for the largest share of India's CO₂ emissions

~70% of India's electricity comes from coal-fired thermal power plants

Good to know

India is gradually increasing renewable energy capacity but coal remains dominant

Why Power Sector Dominates

India's electricity generation relies heavily on coal-fired thermal plants because coal is domestically abundant and historically cheaper. This makes the power sector the single largest source of CO₂ emissions, even as India rapidly expands renewable capacity.

Power Sector Emission Drivers

# Power Sector CO₂ Emissions
## Coal Dependence
- Domestic availability
- Low cost
- Existing infrastructure
- Technical expertise
## Growing Demand
- Industrial growth
- Urbanization
- Rural electrification
- Air conditioning
## Transition Challenges
- Grid integration
- Storage costs
- Stranded assets
- Just transition
Exam traps

Power sector is largest CO₂ source, not transport (unlike in some developed countries)

Coal's 70% share in electricity makes this sector emission-intensive despite renewable growth

Don't confuse electricity generation with total energy consumption - transport uses oil, not coal

Per Capita Emissions Comparison

Per Capita CO₂ Emissions: India vs Developed Countries

Must know

India's per capita emissions are 1.9-2.0 tonnes CO₂/year, not 0.5 tonnes as stated

This is still much lower than USA (15 t) and China (8 t) per capita

Good to know

Per capita emissions reflect consumption patterns and development level

Context

Per capita emissions measure the average CO₂ footprint per person, reflecting lifestyle, consumption, and energy access. India's relatively low per capita emissions highlight the equity dimension in climate discussions - high population but lower individual consumption.

Exam traps

0.5 t/capita would place India at Bangladesh level - actual figure is 1.9-2.0 tonnes

Don't confuse India's high total emissions with low per capita - large population creates this gap

Per capita matters for climate equity - India argues developed countries should cut first
