14.CLIMATE RESILIENT CONST..



CLIMATE RESILIENT CONSTRUCTION – INTEGRATION OF  ENVIRONMENTAL CLEARANCE WITH SANCTION  

Land, Air, Noise, Water, Energy, biological/ socio-economic/ solid / other waste management are the main facets considered in relation to Pre, During and Post Building Construction for Sustainable Environment Management. Therefore, it is necessary for the building process to ensure compliance to various conditions laid down by the Ministry of Environment, Forest and Climate Change.  

The building construction sector is a major contributor towards carbon footprints which affects climate change. India is committed towards mitigating the effects of climate change and moving towards internationally accepted norms for environmental friendly building construction. Currently this objective of environmental safeguard is achieved through obtaining a specific environmental clearance (EC) for any construction project having a size of more than 20,000 sq mts. This is administered under notification of Ministry of Environment, Forest and Climate Change.  

With rapid urbanisation and growth of Indian economy, it is anticipated that the construction activity will experience a proportionate growth. Government is also committed towards streamlining of clearances for buildings and real estate sector and empowering the urban local bodies with an objective of Ease of Doing Business.  

14.1 Environmental conditions for compliance during Building approvals

The Ministry of Environment, Forest and Climate Change has now decided to integrate the environmental concerns into building plan approval process and empowering the concerned local body/development authority to approve and certify compliance of stipulated requirements. The new building construction proposals are classified in the following 3 categories:-

1) Conditions for Category ‘A’ Buildings: Built-up Area 5000 sqmt – 20000 sqmt

2) Conditions for Category ‘B’ Buildings: Built-up Area 20000 sqmt – 50000 sqmt

3) Conditions for Category ‘C’ Buildings: Built-up Area 50000sqmt – 150000 sqmt  

A local Authority, i.e. ULB/DA/any other body authorized to sanction building plans shall approve the building plans by ensuring the stipulated conditions in Table 14.1, 14.2 and 14.3 for the respective categories of buildings.  

These environmental conditions may be suitably integrated in the building permission conditions so that their effective implementation could be ensured by the local authority while sanctioning building plans in their respective urban areas.  

However, in order to empower the Local Authority, the State/UT Governments will be required to amend their building by-laws to incorporate a specific set of conditions as given in the Tables 14.1, 14.2 and 14.3. Once these conditions are incorporated through due process adopted by States/UTs into the Building Bye-Laws and made applicable and enforceable by their local authority, States / UTs will be required to approach M/o Environment, Forest and Climate Change alongwith the Draft notification for seeking clearance that the requirements have been met and after getting the clearance from M/o EFCC, State/UT shall issue notification of Building Bye-laws alongwith stipulated conditions. Copy of the notification shall be forwarded to Ministry of Environment, Forest and Climate Change so that they may notify the particular State or part thereof for which conditions have been suitably integrated to delegate the powers to the Local Authority. Thereafter, for such notified area no separate prior Environmental clearance will be required. However, for those States/UTs or part of the States/UTs where these conditions have not been incorporated in the Building Bye-Laws, the existing arrangement of mandatory prior Environment clearance by State Environment Impact Assessment Authority shall continue to hold.

States are, therefore, advised to amend their building by-laws by incorporating the set of conditions for each category A, B and C as mentioned above either for the entire State/UT or clearly identified part thereof, where they would like to integrate the environmental clearance conditions with building permissions and empower the local authority to examine, stipulate and ensure compliance of conditions required to address environmental concerns. The State/UT should submit such proposal/ notification at draft stage as well as a copy of the final notification to the M/o Environment, Forest and Climate Change

i. For building plans with a total built-up area between 5,000 sqm and 1,50,000 sqm, environment clearance will be required to be synchronized with the bye-laws.  

ii. The concerned Urban local body, authorized to sanction building plans, shall ensure at the time of sanctioning a building plan that the environmental requirements stipulated in Table 14.1 (for above 5,000 sqm and up to 20,000 sqm), Table 14.2 (for above 20,000 sqm and up to 50,000 sqm) and Table 14.3 (for above 50,000 sqm and up to 1,50,000 sqm), as the case may be, are complied with.
