Three Pillars of Sustainability

The Evolution of Sustainability Thinking

Sustainability is about living within ecological and social limits so that both present and future generations can meet their needs. The term itself is recent, but its roots go back centuries.

• Early seeds: In the 18th century, Hans Carl von Carlowitz wrote about sustainable forestry. The modern push began after WWII with the environmental movement, concerns about nuclear energy, pollution, and hazardous waste.
• Key thinkers:
  • Rachel Carson (1962, Silent Spring) connected environmental damage directly to human health.
  • E.F. Schumacher and Herman Daly argued that economies must recognise nature’s finiteness.
  • Club of Rome (1972, Limits to Growth) introduced systems thinking into global environmental debates.
• Brundtland Report (1987): The UN’s Our Common Future gave the most enduring definition:

Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

This definition emphasises both current needs (especially for the vulnerable) and future generations’ rights.

• Four core ideas (Caradonna):
  1. Human society, economy, and natural environment are interconnected.
  2. Societies must stay within ecological limits.
  3. Future‑oriented planning is essential.
  4. Small‑scale and local solutions often provide greater resilience.
• Alternative definitions:
  • Oxford English Dictionary: “the property of being maintained or continued while avoiding long‑term depletion of natural resources.”
  • University of British Columbia: “simultaneous improvements in human and environmental wellbeing, not just reductions in harm.”
• Critical note: The standard history of sustainability has been shaped mainly by European and North American printed sources, marginalising indigenous, global‑south, and traditional knowledge. Modern efforts are correcting this.

Key Milestones in Sustainability and Corporate Responsibility

The parallel rise of corporate social responsibility (CSR) and sustainability thinking is shown by a sequence of global events, most of which are Western‑centric.

Exam tip: Be aware that Indian events like the Bhopal gas disaster are absent from this standard timeline — the course treats Indian environmentalism separately.

The Anthropocene and Planetary Boundaries

Human activity has become the dominant force shaping Earth’s systems in the current geological epoch.

• Anthropocene (Nobel laureate Paul Crutzen): The last ~200 years of industrialisation, where human population growth and technology have a decisive impact on the planetary biosphere.
• Planetary Boundaries Framework (introduced 2009 by Johan Rockström, Stockholm Resilience Centre, and Will Steffen): Nine identified boundaries that define a safe operating space for humanity.
• Current status (2023): Of the nine boundaries, six have been crossed, with many under severe stress. The number has increased from three in 2009 to four in 2015 and six in 2023.
• Consequences: In 2023, up to 12,000 deaths were directly attributed to climate change, costing $200 billion. Rockström warns of an 18% loss of global GDP by 2050 under business‑as‑usual.

Global Responses: Agenda 2030 and the SDGs

In 2015, UN member states adopted Agenda 2030 — a plan for people, planet, and prosperity.

• Features:
  • A common language for talking about sustainability.
  • Illustrates the breadth of sustainability (includes education, poverty, gender, peace, justice).
  • The 17 Sustainable Development Goals (SDGs) are “big, hairy, audacious goals” (BHAGs) for the planet.
• Role of business: A 2019 UN Global Compact report declared the current decade “the decade to deliver” and called for business action. Private sector contributes 75% of global GDP and must be mobilised.
• Low business contribution areas (CEO self‑assessment): SDG 1 (No Poverty) 25%; SDG 2 (Zero Hunger) 20%; SDG 14 (Life Below Water) 13%; SDG 15 (Life on Land) 21%.
• Systemic transformation: The SDGs are not just development goals but a call to rethink institutions and economic systems for justice, resilience, and long‑term wellbeing. As Theis & Tomkin put it, sustainability is a “meta‑discipline.”

Key takeaways

• Sustainability emerged from 18th‑century forestry and crystallised in the 1970–80s; the Brundtland definition (1987) remains the most cited.
• Four core ideas: interconnection, ecological limits, long‑term planning, and local resilience.
• A timeline of CSR/sustainability milestones shows a shift from shareholder primacy to ESG and SDGs.
• The Anthropocene and Planetary Boundaries frameworks highlight that humans have crossed six of nine Earth‑system boundaries.
• The SDGs (Agenda 2030) are a global plan linking poverty, inequality, and environment; business participation is critical but currently weak in several goals.

Triple Bottom Line (TBL)

The Triple Bottom Line reframes business success beyond profit alone. Intuitively: a company should be judged not just by what it earns, but by what it does to people and the planet. Popularized by John Elkington in 1994, the TBL gives managers a language to account for social and environmental performance alongside financial results.

Elkington’s 1997 book Cannibals with Forks: The Triple Bottom Line of 21st Century Business cemented the idea. The framework now underpins global sustainability reporting and corporate responsibility.

People, Planet, Profit (3Ps)

The three pillars of sustainability — economic, social, environmental — are relabelled for business as:

• People (social equity)
• Planet (environmental protection)
• Profit (economic viability)

These dimensions are interdependent, not silos. The overlap creates new qualities:

Exam tip: The 3P model is the most common business adaptation of the three pillars. Know the intersections — bearable, equitable, viable — as they often appear in diagram-based questions.

Critiques of TBL

Despite its utility, the TBL can oversimplify deep systemic conflicts. Munro warns that a clear definition of sustainability will not resolve sustainability — action and performance matter more than rhetoric. The model works best when accompanied by dialogues about values and practices.

Greenwashing — making misleading claims about sustainability efforts — is a direct risk when companies adopt TBL language without genuine change.

Business applications (evidence from practice)

A 2016 Harvard Business Review article by Whelan and Fink, The Comprehensive Business Case for Sustainability, summarises how leading companies embed sustainability:

Embedding sustainability into a company’s ethos creates a more engaged, motivated, and purpose-driven workforce.

Key takeaways

• TBL (People, Planet, Profit) expands business accountability beyond financial metrics.
• The three pillars are interdependent; their intersections (bearable, equitable, viable) constitute sustainability.
• Critiques: TBL can mask conflict and promote greenwashing if not paired with genuine action.
• Evidence shows TBL drives innovation, financial performance, risk management, and customer loyalty.
• The framework is a tool for systemic thinking, not a final answer.

Sustainability Careers

Chief Sustainability Officers (CSOs) have surged in corporate ranks. In 2021 more CSOs were hired than in the previous five years combined. In the US, CSOs grew 228% over a decade (29 in 2011 → 95 in 2021). Globally, 394 new CSOs were appointed between 2020 and 2021, nearly equaling the 414 appointed in the entire prior eight years (2011–2019). Notably, 31 companies hired their first-ever CSO in 2020.

Eight Responsibilities of CSOs (Farri, Cervini & Rosani, HBR 2023)

CSO Demographics and Career Pathways

• Gender: share of women rose from 28% (2011) to 54% (2021).
• Education: 74% hold a master’s degree, 18% a bachelor’s. Typical backgrounds: business administration, management, finance, public administration, social entrepreneurship.
• Reporting lines: >66% report directly to CEO or President, signalling strategic importance.
• Career paths: corporate sustainability, ESG management, supply chain sustainability, sustainability finance, non-profit/public sector leadership. Specific roles: CSO, ESG analyst/manager, CSR manager, sustainable supply chain manager, environmental consultant, sustainability communication specialist. (Not all roles equally established in Indian corporations.)

Exam tip: The 228% growth and the fact that 2020–2021 saw nearly as many CSO hires as the prior eight years are high-yield statistics for questions on the business case for sustainability.

Key takeaways

• CSO roles expanded dramatically in the last decade, especially post-2020.
• CSOs balance compliance, strategy, culture, and innovation.
• The role is increasingly female, advanced-degree holders, and reports directly to top leadership.

What Is Climate Change?

Climate change refers to long-term alterations in global temperatures and weather patterns. It differs from global warming (the rise in average surface temperature) because it includes broader shifts (precipitation, storms, etc.).

Drivers and Mechanism

• Anthropogenic causes: primarily burning fossil fuels → release of greenhouse gases (CO₂, CH₄, N₂O).
• Greenhouse effect: natural process that traps heat; excessive emissions intensify it, causing global warming.
• Energy shift: transition from renewable current sunlight (wood, crops) to ancient sunlight (fossil fuels) during the Industrial Revolution massively increased carbon emissions.

Feedback Loops and Tipping Points

The climate system contains feedback loops that can amplify or dampen change:

• Thawing permafrost releases methane (a potent greenhouse gas), further accelerating warming.
• These feedbacks can lead to tipping points – irreversible chain reactions. Greta Thunberg (2019): “The popular idea of cutting emissions in half in 10 years only gives us a 50% chance of staying below 1.5°C … [that] does not include tipping points.”

IPCC Sixth Assessment Report (AR6)

• Human activities have unequally caused global warming.
• Global surface temperature has increased faster since 1970 than in any other 50‑year period over the last 2000 years.

Mitigation vs. Adaptation

Key takeaways

• Climate change ≠ global warming; it is broader.
• Human activity amplifies the natural greenhouse effect, with feedback loops creating risk of irreversible tipping points.
• Mitigation and adaptation are complementary strategies, differing in scale, timeframe, and purpose.

Radical Environmentalism

Radical environmentalism critiques modern industrial society, arguing mainstream reforms are insufficient. Emerging in the 1970s–80s, it includes eco-anarchism, deep ecology, and green radicalism, often aligning with anti‑capitalist, anti‑globalization, and indigenous rights movements.

Deep Ecology (Arne Naess, 1973)

• Shallow ecology: focuses on pollution control and resource efficiency.
• Deep ecology: calls for a profound rethinking of human–nature relationships.
  • All life has intrinsic value, independent of human utility.
  • Promotes ecocentrism (humans as part of a broader ecological community).
  • Challenges anthropocentrism and the instrumental view of nature.
• Influence: laid moral groundwork for bioregionalism and grassroots ecological resistance.

Gaia Hypothesis (James Lovelock & Lynn Margulis, 1970s)

• Earth behaves as a self‑regulating living organism (biological metaphor, not mechanistic).
• Complex feedback loops maintain conditions conducive to life.
• Initially controversial, but gained scientific support for promoting planetary thinking and interdependence.
• Foundational to contemporary sustainability science and Earth Systems research.

Environmental & Ecological Economics

• Environmental economics (Herman Daly, E.F. Schumacher, Kenneth Boulding) emerged to address external costs of degradation.
  • Critiques perpetual growth; advocates steady‑state economics respecting ecological limits.
  • Tools: carbon pricing, natural capital valuation, polluter‑pays principle.
• Ecological economics (1980s onward): more critical offshoot; economy is embedded within and constrained by Earth’s ecological system.

Exam tip: Deep ecology’s ecocentrism vs. anthropocentrism is a classic compare/contrast question. Similarly, distinguish environmental economics (internalize costs) from ecological economics (economy as subsystem of ecosystem).

Key takeaways

• Radical environmentalism provides ethical foundations beyond carbon credits.
• Deep ecology asserts intrinsic value of all life; Gaia hypothesis sees Earth as a self‑regulating system.
• Environmental and ecological economics both challenge unlimited growth, but ecological economics is more systemic.

Pandemic and Indian Environmentalism

COVID‑19 Lockdown’s Environmental Impact

• Air quality: In May 2020 and 2021, the Himalayan range (Dhauladhar, even Mount Everest) became visible from Indian cities for the first time in ~30 years due to reduced pollution.
• Quantified benefits (Talukdar et al., Dec 2024):
  • Excess risk from PM decreased by 52% in India → ~0.65 million lives saved per year.
  • CO concentration dropped 84%, NO₂ 69%, SO₂ 5%, ozone 32%, PM₁₀ 18% (PM₂.5 not significantly reduced).
• Water & coastal areas: cleaner due to reduced industrial effluence and tourism.
• Negative impacts: surge in plastic waste (rollback of single‑use plastic bans), disruption of recycling chains, increased domestic waste from online consumption.

Rise of Indian Environmentalism

• Social media mentions of nature/biodiversity increased from 30 million to 50 million (2016–2020 data).
• Online searches for sustainable goods rose 71% (Economist Intelligence Unit/WWF).
• Grassroots initiatives: e.g., website indianenvironmentalism.com by young activists during pandemic.
• Notable figures:
  • Arati Kumar Rao (author of Marginland): proponent of slow journalism; left corporate career to document environmental stories.
  • Amitav Ghosh (The Great Derangement): questions why literature and politics have failed to address climate change.
  • Gandhi (quoted, 1928): warned against Indian industrialism imitating the West; seen as an inspiring figure in Indian environmentalism.
• Environmental historian Ramachandra Guha has traced India’s distinctive environmental trajectory, different from the West.

Key takeaways

• Pandemic lockdowns provided a temporary, measurable improvement in air/water quality and visibility, but also negative side effects (plastic waste).
• Indian environmentalism has unique roots (Gandhian thought, grassroots activism) and has gained momentum post‑pandemic.
• Slow journalism and youth-led digital platforms are emerging forces.

The Radical Roots of Indian Environmentalism

Indian environmentalism did not begin with parks or wilderness preservation. It grew from survival struggles of rural and tribal communities over forests, water, and land—where protecting nature is inseparable from protecting livelihoods and justice. Thinker Ramachandra Guha critiques the export of Western "deep ecology" and argues for an environmentalism grounded in social context, equity, and participatory governance.

Guha’s Critique of Deep Ecology

Deep ecology calls for a shift from anthropocentric (human-centered) to biocentric (nature-centered) ethics. Guha (1998) challenges its claim to universality, arguing it reflects American cultural history—vast wilderness and a consumer society—and often becomes a tool of green imperialism when applied to the global south.

Exam tip: Guha’s main argument: deep ecology ignores the social and political roots of environmental degradation. The real crisis is overconsumption by the wealthy, not population in the Global South.

Overconsumption and the Gandhian Alternative

Guha’s book How Much Should a Person Consume? (borrowing from economist John Kenneth Galbraith) asks why material consumption became the measure of success. He quotes poet Wendell Berry:

Conservation is going to prove increasingly futile and meaningless if its prescriptions and forbiddings are not positively answered by an economy that rewards and enforces good use.

Gandhian voluntary simplicity offers a counter-model: "India following the Western model of industrialization would strip the world bare like locusts." Guha frames this as foundational to Indian environmental thought.

Guha’s Socioecological Typology

Guha classifies Indian society into three groups based on their relationship with resources:

Indian development, Guha argues, transfers resources from the poor to the elite, intensifying ecological injustice.

Key Movements in Indian Environmentalism

Indian environmentalism began with community-led protests, not scientists. The timeline below shows major movements.

Details of each movement:

• Bishnoi (1730): Amrita Devi Bishnoi and 363 others sacrificed their lives to prevent felling of sacred Khejri trees by royal decree. Sacred groves (13,000–100,000 documented) remain living examples of community conservation.
• Chipko (1973): Villagers, especially women, hugged trees to stop logging for a sports goods factory. Leaders: Chandi Prasad Bhatt, Sunderlal Bahuguna, Gaura Devi. Marked birth of modern Indian environmentalism and ecofeminism.
• Silent Valley (1978): Led by the Kerala Sastra Sahithya Parishad (KSSP)—a people’s science movement. Mobilised awareness against a hydroelectric dam threatening a tropical rainforest. The dam was cancelled and Silent Valley National Park created.
• Jungle Bachao Andolan (1982–85): Tribal communities in Jharkhand protested government plans to replace natural forests with commercial tea cultivation. Emphasised indigenous rights and traditional forest management. The report Dying Wisdom (Centre for Science and Environment) later documented this traditional knowledge.
• Appiko (1983): Pandurang Hegde led villagers in Karnataka to hug trees, stopping deforestation in the Western Ghats.
• Narmada Bachao Andolan (1985 onward): Mass movement against large dams on the Narmada River, led by Medha Patkar and Baba Amte. Brought global attention to social and ecological costs of development. Arundhati Roy’s essay The Greater Common Good asked: “Who bears the cost and who benefits?”

Institutional and Professional Responses

• Department of Environment created in 1980, upgraded to Ministry of Environment and Forests in 1985—formal recognition of environmental issues in governance.
• Growth of research centres: Centre for Ecological Sciences (IISc), academic programmes in ecological economics and environmental history. These complemented grassroots activism with scientific and policy expertise.

Three Waves of Indian Environmentalism (Guha, Speaking with Nature)

Guha: “The third wave is urban, middle class, and legalistic. It is about the right to clean air and water and about holding the state accountable through the courts. It is less about survival and more about quality of life.”

Session Recap (Indian Environmentalism Part)

• Indian environmentalism is rooted in social justice, not wilderness preservation.
• Deep ecology often ignores overconsumption and can become green imperialism.
• Grassroots movements (Chipko, Silent Valley, Narmada) show that women, tribals, and local communities drive change.
• Guha’s three waves illustrate transition from survival to quality-of-life concerns.
• The pandemic proved that rapid change is possible (cleaner air, visible mountains).
• Assignment: identify local movements in your own area.

Key Takeaways

• Indian environmentalism emerged from survival struggles over forests, water, and land—not from wilderness idealism.
• Ramachandra Guha critiques deep ecology as culturally arrogant and blind to overconsumption in the Global North.
• Gandhian voluntary simplicity and community-led action are core to Indian environmental thought.
• Major movements: Bishnoi (sacred groves), Chipko (ecofeminism), Silent Valley (science-based activism), Narmada Bachao (ecological justice).
• Environmentalism in India is inseparable from equity, livelihoods, and participatory governance.
• The three waves show a shift from rural survival to urban legalistic environmentalism.
