Green happiness As a priority for reducing carbon emissions Green buildings are important.

The construction of green buildings is increasing in the country to achieve carbon emission reduction targets. Real estate developers are promoting green buildings to achieve carbon emission reduction goals. Construction activities that had come to a halt during the pandemic have picked up significantly later. Currently, construction projects are progressing vigorously nationwide. In this process, India’s construction sector is emerging as the third-largest in the world. Currently, the United States, China, and Japan are in the top three positions.

The country’s construction sector is likely to reach the third position in the global ranking by 2030. Furthermore, efforts to make the construction sector carbon-neutral are evident. Building construction is being considered to be done carbon-free.

Two crucial materials used in traditional construction, steel and cement, are both carbon-intensive. Hence, there is a significant emphasis on reducing carbon emissions in construction through the utilisation of alternative materials such as aluminum and other metals. Additionally, reducing wastage in construction, especially in concrete production, is vital. Recycling materials, such as those used in 25% of the projects in the country, also contribute to reducing carbon emissions. This has been confirmed to be cost-effective. Moreover, the use of fly ash instead of conventional cement can significantly reduce emissions. However, there are no laws currently in place to mandate such practices. These practices would help to reduce environmental stress caused by construction activities, such as soil erosion, loss of habitats, and biodiversity.

Efforts are being made to promote the use of environmentally friendly practices in construction, such as labor, construction, and cooling waste management. Moreover, there is the opportunity to reuse aluminum and other metals in construction. Additionally, proper management of construction waste on-site can prevent pollution. This pathway offers the opportunity to reduce waste and emissions through pre-fabrication, modular construction, and 3D printing with modern technology. India’s first 3D printed public building, the Kempegowda Post Office in Bengaluru, was constructed by L&T in 2023.
