Given below are two statements:
Statement I: To address the problem of climate change, it is essential for the world to achieve ‘net zero’ carbon emissions by the year 2050.
Statement II: There is zero carbon emission associated with the production of gray hydrogen.
In light of the above statements, choose the correct answer from the options given below:
Answer: C. Statement I is true but Statement II is false — CONCEPTNet zero means that human-caused greenhouse-gas emissions are reduced deeply and any remaining emissions are balanced by removals; it does not mean…
- A.
Both Statement I and Statement II are true
- B.
Both Statement I and Statement II are false
- C.
Statement I is true but Statement II is false
- D.
Statement I is false but Statement II is true
Show answer & explanation
Correct answer: C
CONCEPT
Net zero means that human-caused greenhouse-gas emissions are reduced deeply and any remaining emissions are balanced by removals; it does not mean that every activity emits absolutely nothing.
Hydrogen colour labels describe the production route: gray hydrogen is generally made from fossil fuels without carbon capture, so its production is emissions-intensive.
APPLICATION
Statement I: IPCC pathways that limit warming to 1.5°C with no overshoot or only limited overshoot reach global net-zero carbon dioxide around 2050. This supports the climate-mitigation claim.
Statement II: IEA estimates unabated natural-gas hydrogen at about 10–14 kg CO₂-equivalent per kg of hydrogen. Therefore gray-hydrogen production is not associated with zero carbon emissions.
CONTRAST
Both statements true: this conflicts with the documented emissions from gray hydrogen.
Both statements false: this rejects the supported net-zero pathway as well as the zero-emission claim.
Statement I true and Statement II false: this matches the climate pathway and the emissions profile of gray hydrogen.
Statement I false and Statement II true: this reverses both evidence-based evaluations.
RESULT
Hence, Statement I is true but Statement II is false.
