- With a rapidly growing urban population, India is on the threshold of massive infrastructure development.
- This development would create a huge demand for construction activity. Current construction practices in India, however, have an immensely detrimental impact on the environment.
- Construction activity is responsible for 23% of air pollution in cities, 50% of climate change due to gaseous emissions, 40% of contamination of potable water, 50% of pollution due to the dumping of waste in landfills, and 50% of ozone-depleting processes.

- The construction industry involves resource-intensive processes that engender demand for materials, land, energy, and water.
- Inefficient practices followed currently will increasingly strain our finite pool of resources if the consumption processes do not become more informed, responsible, efficient, and judicious.
- The shortage of water from conventional sources has not only affected the construction industry in major Indian cities, such as Bengaluru and Chennai, but has also been exacerbated by it.
- The intent of this section is to ensure reduced environmental impact of construction activity by introducing sustainable construction practices and measures to reduce harmful emissions, dust generation, contamination and wastage of water, loss of vegetation, loss of fertile soil, and generation of construction waste.
- To ensure holistic sustainable development, this section promotes preservation of natural site features to maintain healthy ecosystems, better site management practices during construction to curb negative environmental impacts, and efficient management of construction material and waste to minimize dependence on landfills.
- This section consists of the following three criteria as mentioned in Table ( Given below ).
