India produces more than 277 million tonnes of solid waste every year, which is likely to touch 387 million tonnes by 2030*. Of the total collected waste, only 20 per cent (55 MT per year) is processed and the remaining 80 per cent (221 MT per year) is dumped as landfill. The country also generates 150 million tonnes per year of construction and demolition (C&D) waste. The existing recycling capacity is only a meagre 2.3 million tonnes per year which is about 1.5 per cent.
With the limited usable land area available in the country, the increased landfill becomes a major challenge. The landfill leads to land, air and water pollution which affects the health and well-being of people in the surroundings. The landfill also leads to emission of methane and other greenhouse gases which contributes to global warming and climate change. There is an imminent need for addressing the issues related to waste generation and their landfill.
There are multiple challenges associated in addressing the waste generation, handling and diversion to landfill. Some of the challenges include the nature of the sector, which is largely unorganised, lack of segregation of waste at source, non-availability of recycling facilities, financial viability and the people mindset.
Against this background, IGBC's mission on Net Zero aims at addressing the issues related to waste generation during construction, operation and maintenance of the buildings and built environment through Net Zero Waste Rating System initiative. This rating system on Net Zero Waste Rating System is a tool to facilitate buildings and built environment to adopt 3R (reduce, reuse, recycle) principles to address waste generation and avoid waste being sent to landfill.

Key benefits of adopting 'Net Zero Waste Rating System for Buildings & Built Environment' for the project proponents are as below:
The 'Net Zero Waste Rating System for Buildings & Built Environment' can be applied on all building typologies including residential, commercial, factories, interior fitouts, healthcare, education institutions, retail shops, transit buildings, townships, cities, etc.
This rating system can be adopted for both New & Existing buildings and built environment. Refer Design & Construction for New Projects and Operation credits for Existing projects
Depending upon the project proponent aspiring to achieve 'Net Zero Waste to Landfill' rating for their building, the scope can be limited to design & construction (or) operation.
The suggested scope for the project proponents is as below:
IGBC Net Zero Waste to Landfill Rating System for Buildings & Built Environment addresses green features under the following categories:
The guidelines detailed under each mandatory requirement & credit enables the design and construction of interiors in buildings of all sizes and types (as defined in scope). Different levels of green building certification are awarded based on the total credits earned. However, every project aiming for Net Zero Waste Rating System for Buildings & Built Environment should meet certain mandatory requirements, which are non-negotiable.
The rating awarded for IGBC Net Zero Waste to Landfill under Design & Construction phase or Operations phase would be valid for a period of 3 years. The projects certified under Design & Construction phase shall apply for Operations phase certification with the prevailing version. The projects certified under Operations phase shall apply for recertification with the prevailing version.
Projects can apply for IGBC Net Zero certification during Design and Operation phase, and following are the types of certification:
