Green growth
Topic: Environment and Sustainable Development · NCERT: Beyond NCERT
Meaning
Green growth is economic growth that is decoupled from emissions and environmental damage. Decoupling means breaking the link between them, so the economy (GDP) keeps growing while pressure on nature stops rising or falls. The OECD and the World Bank promote this idea.
It matters because it answers a hard question for countries like India: can we keep growing to remove poverty without destroying the air, water, forests and climate? Green growth says yes, but only if each unit of output uses fewer resources and causes less pollution.
- Emission intensity = Emissions ÷ GDP. Green growth needs this ratio to keep falling.
Explanation
How green growth works: decoupling
- The old pattern: more output → more coal, oil, timber and water used → more pollution.
- The green growth pattern: more output, but from cleaner energy, efficient technology and less waste.
- There are two levels of decoupling:
- Relative decoupling: emissions still rise, but more slowly than GDP, so emission intensity falls.
-
Absolute decoupling: emissions fall while GDP rises. This is real green growth.
-
Worked example (GDP grows 7% in a year):
| Case | Emissions change | Type |
|---|---|---|
| A | +4% | Relative decoupling (4% < 7%) |
| B | −2% | Absolute decoupling |
| C | +7% or more | No decoupling |
- Only Case B lowers the total harm to the planet. Case A slows the damage but does not stop it.
The tools behind it
- Input-efficient technology: getting more output from fewer inputs. This is Herman Daly's Rule 2.
- Shift to renewables: use up coal and oil only as fast as solar, wind and other substitutes are built. This is Daly's Rule 4.
- Pricing pollution: pollution is a negative externality (a cost the polluter does not pay; others pay it). It can be corrected through:
- taxes
- standards
-
"polluter pays" rules
-
Harvest within limits: take fish, timber or groundwater no faster than nature replaces them. This is Daly's Rule 3.
What can weaken green growth
- Rebound effect (Jevons paradox):
- Better efficiency lowers the cost of using something.
- So people use more of it.
- The extra use eats up part of the saving, or even all of it.
- Worked example: a new car uses 20% less fuel per km. The expected saving is 20 litres a month. The owner now drives more, so the actual saving is only 12 litres.
- Rebound = (20 − 12) ÷ 20 = 40%.
-
If the extra use is bigger than the saving, total use rises. This is called backfire.
-
Pollution haven hypothesis: dirty industry moves to countries with weaker environmental rules.
- A rich country's emissions may seem to fall, but part of that pollution has only moved abroad.
-
Its imports still carry that pollution, so this is not true green growth.
-
Weak link for global harms: the Environmental Kuznets Curve (EKC) says pollution first rises and then falls as income grows (an inverted U; Grossman and Krueger, 1991).
- It holds better for local pollutants such as SO₂ (sulphur dioxide).
- It holds much less well for CO₂ and loss of biodiversity. So income growth alone will not bring green growth. Policy is needed.
In India
- Union Budget 2023-24: "Green Growth" was one of the seven priorities (Saptarishi) of the Budget. This made it a named goal of Union economic policy.
- Institutions:
- The Central Pollution Control Board (CPCB), set up in 1974 under the Water (Prevention and Control of Pollution) Act, 1974, handles the pollution-control side.
-
NITI Aayog's SDG India Index tracks progress on the SDGs, including the environmental goals. India's composite score rose to 71 in 2023-24 [1].
-
Demand-side support through Mission LiFE:
- Mission LiFE was launched at the Statue of Unity, Ekta Nagar, Kevadia (Gujarat) in October 2022, together with UN Secretary-General António Guterres [2].
- It aims to get at least 1 billion people to take pro-environment action during 2022-2027 [3].
- Logic: green growth mostly depends on cleaner supply, meaning better technology. LiFE adds the demand side: mindful use instead of wasteful consumption. This matches Gandhi's idea of "need, not greed".
Don't confuse with
- Green economy (UNEP, 2011): an economy that is low-carbon, resource-efficient and socially inclusive. It explicitly adds a social-inclusion goal. Green growth focuses mainly on decoupling growth from harm.
- Sustainable development (Brundtland Commission, Our Common Future, 1987): meeting present needs without harming the ability of future generations to meet theirs. It is the broader goal. Green growth is one path to reach it.
- Degrowth: rich countries should deliberately shrink production and consumption. Green growth keeps growth going and makes it cleaner. Developing countries prefer green growth because they still need growth to remove poverty.
- Relative decoupling: emissions still rise, only more slowly than GDP. In exam questions, only absolute decoupling (emissions ↓ while GDP ↑) means real green growth.
Prelims Hooks
- Green growth is promoted by the OECD and the World Bank. Green economy is a UNEP (2011) idea. Watch for questions that swap the two institutions.
- "Green Growth" was one of the seven Saptarishi priorities of the Union Budget 2023-24.
- Absolute decoupling: emissions ↓ while GDP ↑. Relative decoupling: emissions ↑, but more slowly than GDP.
- Rebound effect (Jevons paradox): efficiency gains lead to more use, which cuts the expected savings. If total use actually rises, this is called backfire.
- EKC is an inverted U (Grossman-Krueger, 1991). The evidence is stronger for SO₂ than for CO₂.
- Doughnut economics (Kate Raworth) and planetary boundaries (Johan Rockström, 2009; nine Earth-system limits) criticise growth-led thinking. They are not models of green growth.
Mains Points
- "Grow first, clean up later" does not work for India:
- The EKC is weak for CO₂ and biodiversity, and rich countries' falling curves partly come from moving pollution to other countries.
- So India should aim for absolute decoupling now, through the Green Growth priority of Budget 2023-24 and more renewable energy.
-
Policy must also plan for the rebound effect, because efficiency gains alone may not cut total resource use.
-
Growth with equity (GS-II/III):
- Degrowth may suit rich countries. India still needs growth to remove absolute poverty (people living below a fixed minimum standard).
-
Green growth lets India grow and protect nature together. This supports India's stand on common but differentiated responsibilities in climate talks.
-
Limits of green growth:
- Strong sustainability says some critical natural capital (natural assets that nothing can replace), such as the ozone layer and groundwater aquifers, cannot be traded for GDP. Clean technology alone does not protect them.
- So technology on the supply side needs support on the demand side. One example is Mission LiFE, which aims to mobilise 1 billion people during 2022-27 [3], along with strict protection of critical natural capital.
