Climate risk assessment is a structured process for identifying, analyzing, and evaluating how physical climate hazards (floods, cyclones, heat stress, water scarcity) and transition risks (carbon pricing, policy shifts, technology disruption) threaten business operations, assets, and revenue. India - ranked the 7th most climate-vulnerable country globally - lost $87 billion to climate disasters between 2000 and 2020 according to the World Meteorological Organization, and 75% of Indian districts are now classified as climate hotspots.
If your company operates in India, climate risk is not a future concern - it is a present-day financial exposure. From monsoon variability disrupting supply chains to tightening carbon regulations reshaping export markets, the risks are accelerating across every sector.
This guide explains how to identify and assess climate risks specific to Indian businesses, walks through scenario analysis for different warming pathways, and provides a practical 6-step framework for building a climate risk assessment that aligns with TCFD and ISSB reporting requirements.
What Is Climate Risk Assessment?
Climate risk assessment is the systematic process of identifying, analyzing, and evaluating climate-related risks to an organization's operations, assets, supply chain, and financial performance. It answers three fundamental questions:
- What climate hazards does the business face? - physical events (floods, heat, drought) and transition pressures (regulation, market shifts)
- How exposed and vulnerable is the business? - location of assets, dependency on climate-sensitive inputs, regulatory jurisdiction
- What is the potential financial impact? - asset impairment, revenue loss, increased costs, stranded investments
The TCFD framework (now consolidated into ISSB standards) established climate risk assessment as a core governance and disclosure requirement. Under ISSB S2, companies must disclose how climate-related risks and opportunities affect their strategy, business model, and financial planning - including the use of climate scenario analysis.
For Indian companies, this is not just a reporting exercise. With 75% of districts classified as climate hotspots and the RBI introducing climate risk frameworks for banks, understanding your exposure is now a business continuity requirement.
Physical Risks vs Transition Risks
Climate risks fall into two broad categories, each with distinct drivers and timeframes.
| Category | Type | Examples | Timeframe |
|---|---|---|---|
| Physical - Acute | Extreme weather events | Cyclones, floods, heatwaves, storm surges, wildfires | Immediate / event-driven |
| Physical - Chronic | Long-term climate shifts | Sea level rise, water stress, changing rainfall patterns, sustained temperature increase | Medium to long-term (5-30+ years) |
| Transition - Policy | Regulatory and legal | Carbon pricing, emissions standards, BRSR mandates, EU CSRD requirements | Short to medium-term |
| Transition - Technology | Technology disruption | Renewable energy replacing fossil fuels, EV adoption, green hydrogen, energy storage | Medium-term |
| Transition - Market | Shifting demand and pricing | Consumer preference for low-carbon products, green procurement, stranded fossil fuel assets | Short to medium-term |
| Transition - Reputation | Stakeholder pressure | Investor ESG screening, activist campaigns, greenwashing litigation, employee expectations | Ongoing |
The critical insight is that physical and transition risks are inversely correlated across scenarios. In a high-warming world (3C+), physical risks are severe but transition risks are lower (because policy action was weak). In a rapid-transition world (1.5C), physical risks are more contained but transition risks are intense (aggressive policy, rapid technology shifts, stranded assets). No scenario eliminates both risk types simultaneously.
Why Indian Companies Face High Climate Risk
India sits at the intersection of extreme physical vulnerability and accelerating transition pressure. The numbers are stark:
- $87 billion in climate disaster losses between 2000 and 2020, according to the World Meteorological Organization (WMO)
- 7th most climate-vulnerable country in global risk rankings, with 1.4 billion people exposed to rising temperatures and erratic monsoons
- 75% of Indian districts are climate hotspots - facing increased frequency and intensity of extreme weather events
- Water stress in key industrial states - Gujarat, Maharashtra, Tamil Nadu, Rajasthan, and Karnataka face acute groundwater depletion and surface water variability
- 7,500 km of coastline exposed to sea level rise and cyclone intensification, directly threatening ports, refineries, and coastal manufacturing
Beyond physical exposure, Indian companies face growing transition pressure from multiple directions:
- RBI climate risk framework: The Reserve Bank of India has introduced a climate risk and sustainable finance framework requiring banks and financial institutions to assess climate risks in their lending and investment portfolios
- BRSR and BRSR Core: SEBI's Business Responsibility and Sustainability Reporting now requires listed companies to disclose climate-related risks, GHG emissions, and adaptation measures
- Export market regulations: EU CBAM, CSRD value chain requirements, and growing buyer demands for verified emissions data create transition risk for exporters
- India's net-zero 2070 target: Domestic policy will progressively tighten - the Indian Carbon Market, energy efficiency norms, and renewable energy mandates will reshape operating costs

Climate Scenario Analysis
Scenario analysis is the backbone of climate risk assessment. Rather than predicting a single future, it models multiple plausible pathways to stress-test business resilience. The TCFD and ISSB frameworks recommend analyzing at least two scenarios - typically a low-warming transition scenario and a high-warming physical risk scenario.
Here is how physical and transition impacts vary across the three standard warming pathways:
| Scenario | Physical Impacts | Transition Impacts |
|---|---|---|
| 1.5C (Paris-aligned) | Moderate increase in extreme weather; manageable sea level rise (0.3-0.5m by 2100); some water stress increase | Aggressive carbon pricing (USD 100-200/tCO2 by 2030); rapid fossil fuel phase-out; significant stranded asset risk; strict regulation |
| 2C (Stated Policies) | Noticeable increase in heatwaves, flood frequency; 0.5-0.8m sea level rise; growing water scarcity in arid regions | Moderate carbon pricing (USD 50-100/tCO2); gradual technology transition; some stranded assets; tightening regulation |
| 3C+ (High Emissions) | Severe - frequent extreme events; 1m+ sea level rise; acute water crisis; crop yield decline of 10-25%; uninhabitable heat zones | Low policy pressure; continued fossil fuel reliance; but massive physical damage costs and insurance market disruption |
For Indian companies, the 2C and 3C+ scenarios are particularly concerning because India's geography amplifies physical impacts. Monsoon variability alone can swing agricultural output by 15-20% year-over-year, cascading through food processing, textiles, and rural consumer markets.
There is no "safe" scenario for Indian businesses. A 1.5C pathway means aggressive transition pressure (carbon taxes, technology disruption, stranded assets). A 3C+ pathway means severe physical damage (infrastructure loss, supply chain disruption, worker productivity decline). Companies need adaptation strategies for both.
Who Needs Climate Risk Assessment?
Climate risk assessment is no longer optional for a growing number of Indian companies:
- TCFD/ISSB reporters: Companies aligning with international disclosure standards must conduct scenario-based climate risk analysis and disclose material risks
- BRSR filers: Top 1,000 listed companies on Indian exchanges must report climate-related risks and GHG emissions under SEBI's BRSR framework
- CSRD value chain participants: Indian suppliers to EU companies may be required to provide climate risk data as part of their customers' ESRS disclosures
- Banks and NBFCs under the RBI framework: The Reserve Bank of India requires financial institutions to integrate climate risk into credit assessment, stress testing, and portfolio management
- Institutional investors: Asset managers and pension funds increasingly screen portfolios for climate risk exposure, affecting cost of capital for high-risk companies
- Companies with SBTi targets: Science-based targets require understanding transition pathways and their risk implications
- Companies pursuing net-zero or carbon neutrality: Climate risk assessment informs the transition strategy and identifies dependencies on climate-sensitive operations
Climate Risk by Sector
Different sectors face different combinations of physical and transition risks. Here is a sector-by-sector breakdown for Indian industries:
| Sector | Key Physical Risks | Key Transition Risks |
|---|---|---|
| Manufacturing | Factory flooding, heat stress reducing worker productivity, water scarcity for cooling/processes | Carbon pricing on energy inputs, CBAM on exports, energy efficiency mandates |
| Agriculture & Food | Monsoon variability, drought, crop yield decline, pest pattern shifts | Sustainable sourcing mandates, deforestation-linked regulation, water use restrictions |
| Real Estate & Infrastructure | Coastal flooding, urban heat islands, cyclone damage, foundation subsidence | Green building codes, energy performance standards, climate-adjusted insurance premiums |
| Energy (Oil, Gas, Coal) | Cyclone damage to offshore assets, water stress for thermal plants, pipeline corrosion | Stranded assets, renewable substitution, carbon pricing, fossil fuel subsidy phase-out |
| Textiles & Apparel | Cotton yield variability, water scarcity for dyeing and processing, supply chain disruption | EU due diligence regulation, buyer sustainability requirements, water discharge standards |
| Pharmaceuticals | Water quality and availability for manufacturing, heat-sensitive supply chains, flooding of API units | GHG reporting mandates, green chemistry regulation, Scope 3 disclosure pressure from global buyers |

How to Conduct a Climate Risk Assessment
A robust climate risk assessment follows six steps. This process aligns with TCFD/ISSB guidance and can be scaled from a single facility to an entire corporate portfolio.
Step 1: Identify climate hazards. Map all relevant physical hazards (floods, cyclones, heatwaves, water stress, sea level rise) and transition hazards (carbon pricing, regulation, technology disruption, market shifts) applicable to your operations, supply chain, and markets. Use IPCC regional projections and India-specific climate data.
Step 2: Assess exposure. Determine which assets, facilities, supply chain nodes, and revenue streams are geographically or operationally exposed to each hazard. Map physical asset locations against flood zones, water stress maps, coastal inundation projections, and heat stress indices.
Step 3: Evaluate vulnerability. Assess how susceptible each exposed asset or process is to damage or disruption. A factory in a flood zone with raised foundations and backup power is less vulnerable than one without these adaptations. Consider both inherent vulnerability and existing resilience measures.
Step 4: Model scenarios. Run analysis across at least two climate scenarios (typically 1.5C and 3C+) to understand the range of potential outcomes. Use time horizons relevant to your business - short (2030), medium (2040), and long-term (2050+). Refer to IPCC AR6 scenario data.
Step 5: Quantify financial impact. Translate physical and transition risks into financial metrics - asset impairment, revenue at risk, increased operating costs, capital expenditure for adaptation, insurance cost increases, and potential stranded asset write-downs.
Step 6: Develop adaptation and mitigation plan. Prioritize risks by severity and likelihood. Build adaptation plans for physical risks (relocating assets, water harvesting, heat resilience) and transition plans for regulatory risks (decarbonization roadmap, SBTi targets, technology investment).
Getting Started
For companies new to climate risk assessment, the first step does not need to be complex. Start with a qualitative screening of your top 10 facilities and your five most critical supply chain inputs. Identify which physical hazards each faces and what transition regulations are approaching. This initial screening often reveals that 80% of material risk is concentrated in 20% of assets or operations.
From there, deepen the analysis with quantitative modeling, scenario-based financial projections, and integration into your enterprise risk management (ERM) framework. The goal is not a one-time report but an ongoing risk management capability that informs capital allocation, strategy, and ESG disclosure.
Frequently Asked Questions
Climate risk assessment is a structured process for identifying, analyzing, and evaluating climate-related risks to business operations. It covers physical risks (floods, cyclones, heat stress, water scarcity) and transition risks (policy changes, carbon pricing, technology shifts, market preferences). The TCFD and ISSB frameworks recommend scenario-based analysis across 1.5C, 2C, and 3C+ warming pathways.
India is the 7th most climate-vulnerable country globally. It lost $87 billion to climate disasters between 2000 and 2020 according to the WMO. 75% of Indian districts are climate hotspots facing increased flood risk, monsoon variability, heat stress, water scarcity, and coastal flooding. States like Gujarat, Maharashtra, and Tamil Nadu face acute water stress.
Companies reporting under TCFD or ISSB frameworks, BRSR filers listed on Indian stock exchanges, Indian suppliers in the value chain of EU CSRD reporters, banks and financial institutions under the RBI climate risk framework, and institutional investors conducting portfolio-level climate screening all need climate risk assessment.
Physical risks are direct climate impacts on operations - either acute events like floods, cyclones, and heatwaves, or chronic changes like sea level rise, water stress, and shifting rainfall patterns. Transition risks arise from the shift to a low-carbon economy - policy changes (carbon taxes), technology disruption (renewable energy replacing fossil fuels), market shifts (consumer preferences), and reputational pressure from stakeholders.
