Sustainability & Law

Sustainable development, climate, and India's environmental laws — for design.

≈ 50 min + studio taskByAmogh N P· Architect & interior designer

Sustainable development (Brundtland, 1987) means meeting present needs without compromising the future. Learn climate change and — a different problem — ozone depletion; India’s environmental laws with the correct years; and, for interiors, embodied energy and the green-building rating systems that reward every good decision from the earlier units.

Learning objectives

By the end of this lesson, you will be able to — mapped to the course outcomes for Environmental Studies:

1
CO5 · Understand

Define sustainable development and its three pillars (Brundtland, 1987).

2
CO5 · Analyse

Distinguish ozone-layer depletion from global warming — different problems.

3
CO5 · Understand

State India's environmental laws with the correct years and the role of the CPCB.

4
CO6 · Apply

Apply embodied energy and green-building rating (GRIHA/IGBC/ECBC) to design.

Brundtland, water, ozone ≠ warming

Sustainability and climate

The three pillars; rain-water harvesting and watershed management; the greenhouse effect; and why ozone depletion is a different problem from global warming.[1, 2]

Sustainable development — three pillars Environment Economy Society sustainable “meeting the needs of thepresent without compromisingthe ability of future generationsto meet their own.”— Brundtland, 1987 It means balancing growth with conservation — NOT stopping development.

The Brundtland definition

From Our Common Future (the Brundtland Report, 1987): sustainable development is 'development that meets the needs of the present without compromising the ability of future generations to meet their own needs.' It integrates THREE pillars — environment, economy and society (people, planet, profit). The UN's 17 Sustainable Development Goals (2015, target 2030) extend this idea. It means balancing growth with conservation — NOT stopping development.[1]

Two different problems Ozone depletion UV-B Cause: CFCs destroy thestratospheric ozone layerEffect: more UV-B →skin cancer, cataractsFix: Montreal Protocol, 1987 Global warming Cause: greenhouse gases(CO₂, CH₄) trap heatEffect: temperature rise,sea-level riseFramework: Kyoto / Paris Different causes, effects and treaties — do not confuse the ozone hole with the greenhouse effect.

Acts, EIA, green building

India's laws and the design connection

The five core Acts with the correct years, the CPCB structure and the EIA — and, for interiors, embodied energy and green-building rating (GRIHA, IGBC, ECBC).[1, 3, 4]

Get the years right

India's core environmental laws, with the years students most often misremember: WILDLIFE (Protection) Act 1972; WATER (Prevention & Control of Pollution) Act 1974; FOREST (Conservation) Act 1980; AIR (Prevention & Control of Pollution) Act 1981; ENVIRONMENT (Protection) Act 1986. A common error swaps the Air (1981) and Water (1974) Acts, or dates the EPA to 1984 — that is the Bhopal disaster; the Act is 1986.[1]

Vocabulary

Key terms

Sustainable development

Meeting present needs without compromising future generations (Brundtland, 1987).

Rain-water harvesting

Collecting rainwater for use and for groundwater recharge.

Greenhouse effect

Gases trap outgoing infrared; the enhanced human effect drives global warming.

Ozone depletion

CFCs destroy stratospheric ozone → more UV-B; a different problem from warming (Montreal Protocol 1987).

Environment (Protection) Act 1986

India's umbrella environmental law, enacted after Bhopal (1984).

Embodied energy

Total energy to make and deliver a material — distinct from operational energy.

Apply it

Studio task

For a small fit-out, list three moves that would raise its green-building score: one that cuts embodied energy (a material swap), one that saves water (rain-water harvesting or a fixture), and one that protects indoor air. Cite which Indian rating system (GRIHA, IGBC, ECBC) each would count toward.

Check your understanding

In a nutshell

Recap

Sustainable development (Brundtland, 1987) meets present needs without compromising future generations — three pillars.
Rain-water harvesting serves use AND groundwater recharge; watershed management treats the whole basin.
Ozone depletion (CFCs → UV-B, Montreal 1987) is a DIFFERENT problem from global warming (greenhouse gases).
India's law years: Wildlife 1972, Water 1974, Forest 1980, Air 1981, Environment 1986 (the umbrella act, post-Bhopal).
For interiors: minimise embodied energy and design to green-building rating (GRIHA, IGBC, ECBC).
