Data for two Indian states: State X – GDP Rs.12 lakh crore, population 200 million, CO₂ emissions 450 million tonnes. State Y – GDP Rs.8 lakh crore, population 120 million, CO₂ emissions 300 million tonnes. Compute per‑capita CO₂ emission (tonnes per person) for each state and state which has the higher per‑capita emission.
Answer
State X: 2.25 t/person; State Y: 2.5 t/person; State Y has higher per‑capita emission
The correct answer is State X: 2.25 t/person; State Y: 2.5 t/person; State Y has higher per‑capita emission — Compare 2.25 and 2.5; the larger value belongs to State Y.
Step-by-step solution
- Per‑capita emission = total emissions ÷ population.
- State X: 450 million t ÷ 200 million people = 2.25 t/person.
- State Y: 300 million t ÷ 120 million people = 2.5 t/person.
- Compare 2.25 and 2.5; the larger value belongs to State Y.
Common mistake: Dividing by GDP instead of population
Concept tested: Environmental indicators – per‑capita emissions
