The document discusses Environmental Impact Assessment (EIA) processes, emphasizing their importance in assessing the environmental consequences of proposed projects while ensuring fairness, credibility, and sustainability. It outlines the history of EIA, its procedural stages in India, and introduces the concept of green buildings and green technologies aimed at reducing environmental impact. Additionally, it highlights the challenges and benefits of adopting sustainable practices in construction and energy generation.

3. Environmental impact assessment
Environmental assessment (EA) is the
assessment of the environmental
consequences (positive and negative)
of a plan, policy, program, or concrete
projects prior to the decision to move
forward with the proposed action.

4. Core values of EIA
• Integrity: the EIA process should be
fair, objective, unbiased and balanced.
• Utility: the EIA process should provide
balanced, credible information for
decision making.
• Sustainability: the EIA process should
result in Environmental Safeguard.

5. Environmental Assessment has many
benefits:
•Protection of Environment
•Optimum utilization of resources
•Saves overall time and cost of the project •Promotes
community participation
•Informs decision makers
•Lays base for environmentally sound projects. History
& Evolution of EIA

6. Environmental Impact Assessment started as
a mandatory regulatory procedure originated
in the early 1970’s with the implementation of
the National Environmental Policy act (NEPA)
1969 in the US.
EIA process took off after the mid 1980’s, after
World Bank adopted EIA for major
development projects, in which borrower
country had to undertake the EIA under the
Bank’s supervision.
Now EIA is a formal process in more than 100
countries.

7. Environmental Clearance from central
government is required for 32 categories of
development projects – under industrial
sectors:
• Mining
• Thermal power plants
• River valley
• Infrastructure (road, highways, ports,
harbors, and airports)
• Industries including very small electroplating
in foundry units.

8. EIA Cycles & Procedures Environmental Impact
Assessment – Cycle & Procedure
The EIA process in India is made of the following
phases :-
• Screening
• Scoping & consideration of alternatives
• Baseline data collection
• Impact Analysis
• Mitigation and Environmental Impact statement
• Public hearing
• Environmental Management Plan
• Decision Making
• Monitoring the Clearance Condition

9. Summary of EIA process and Rough Timelines
Stage 1: Screening; Decide project A, B1 or B2
Stage 2: Scoping; Come up with Terms of Reference (TOR)
Prepare preliminary EIA report
Stage 3: Public consultation
Stage 4: Appraisal
Final Decision
Submission of application (Form 1, prelim reports)

11. GREEN BUILDING
Refers to a structure and using process that
is environmentally responsible and resource
efficient throughout a building’s life cycle :
from sitting to design, construction,
operation, maintenance, re novation, and
demolition.
Green building – also known as sustainable
or high performance building increases the
efficiency with which buildings and their sites
use and harvest energy, water, and materials

12. GREEN BUILDING CONCEPT
The ‘GREEN BUILDING’ concept is gaining
importance in various countries, including
India. These are buildings that ensure waste
is minimized at every stage during the
construction and operation of the building,
resulting in low costs, according to experts in
technology.
A Green building is a structure that is
environmentally responsible and resource
efficient throughout it’s life cycle.

13. OBJECTIVE OF GREEN BUILDING
Green building are designed to reduce the
overall impact of the built environment on
human health and the natural environment
by :
Efficiently using energy, water and other
resources.
Protecting occupant health and improving
employee productivity.
Reducing waste, pollution and environment
degradation.

20. • Environmental friendly technology
• Conserve natural resources and the
environment – Sustainable
development
• Radical thinking to change
• Innovative technology

21. GOALS OF GREEN TECHNOLOGY
• Rethinking
• Recycling
• Renewing
• Reducing
• Responsibility

22. TYPES OF GREEN TECHNOLOGY
• GREEN ENERGY
• GREEN BUILDING
• GREEN PURCHASING
• GREEN CHEMISTRY
• GREEN NANOTECHNOLOGY

23. GREEN ENERGY
Reasons for the Need of Green Energy
Natural resources used in the energy
generation process is on the decline
Increasing pollution caused by the non
renewable sources

24. GREEN BUILDING
Hindrances
High initial cost of setting up the projects
Emerging technology, so risks involved
Doesn’t cater to the promoter’s short term
interest of profit making
Advantages
Reduces cost of operation in the long term
Consumers now more environment
conscious

27. GREEN NANOTECHNOLOGY
Aims to minimize potential environmental
and human health risks associated with the
manufacture and use of nanotechnology
products, and to encourage replacement of
existing products with new nano- products
that are more environmentally friendly
throughout their lifecycle.

28. APPLICATIONS
The use of green technology can reduce the
amount of waste and pollution and provide
early warming message that is created during
production, consumption, and impact of
natural disaster.
This special issue provides an international
forum for scientists, engineers, researchers,
technocrats, and academicians for
consolidating research activities.

29. WHAT CAN WE DO?
• Responsibility for the environment
• Rethinking the way we live
• Reducing Exhaustion
• Recycling Waste
• Renewing Energy
