Producing cement is highly carbon-intensive and releases large quantities of greenhouse gases as part of its heating and limestone calcination processes. Extracting limestone also destroys forests and fertile topsoil. But because cement is deeply entrenched in modern construction, the sector remains exceptionally hard to abate

Which process is a major contributor to greenhouse gas emissions in cement production?
Limestone calcination is a crucial step in cement production that releases large quantities of greenhouse gases, making it a significant contributor to the sector's carbon footprint.
Why is the cement sector considered hard to abate?
The cement sector is considered hard to abate because it is deeply entrenched in modern construction, making it challenging to reduce its carbon footprint without significant changes to the industry's infrastructure and practices.
Consider the following statements regarding India's Cement Industry: 1. India's cement production is highly carbon-intensive. 2. Extracting limestone for cement production destroys forests and fertile topsoil. 3. Cement production is the largest contributor to India's greenhouse gas emissions. How many of the above statements are correct?
Statement 1 is correct because India's cement production is highly carbon-intensive (FACT 1). Statement 2 is correct because extracting limestone for cement production destroys forests and fertile topsoil (FACT 2). Statement 3 is incorrect because the fact list does not support the claim that cement production is the largest contributor to India's greenhouse gas emissions.
Consider the following two statements: Statement-I: India's cement production is highly carbon-intensive. Statement-II: This is because the cement production process involves the calcination of limestone, which releases large quantities of greenhouse gases. Which one of the following is correct in respect of the above statements?
Statement 1 is correct because India's cement production is highly carbon-intensive (FACT 1). Statement 2 is correct because it accurately explains why India's cement production is highly carbon-intensive, citing the calcination of limestone as the source of greenhouse gas emissions.
