As the world’s eyes turn to Belém, Brazil, where COP30 is currently underway from November 10-21, 2025, business valuators must pay close attention to emerging climate policies that will fundamentally reshape valuations across assets. This conference focuses on efforts to limit global temperature increases to 1.5°C, presentation of new national action plans (NDCs), and progress on finance pledges made at COP29.
The Financial Stakes: $1.3 Trillion Annual Climate Investment
COP30 aims to secure $1.3 trillion per year in climate investments by 2035, representing one of the largest capital redeployments in modern economic history. For valuation professionals, this signals several critical considerations:
Impact on Discount Rates and Risk Premiums
The scale of required climate investment will affect the cost of capital across sectors. Companies aligned with climate goals may benefit from lower risk premiums, while those exposed to transition risks face increased capital costs. As nations submit updated Nationally Determined Contributions (NDCs) with more ambitious targets, regulatory risk premiums must be recalibrated in valuation models.
Stranded Asset Risk
Scientists warn that without urgent action, global temperatures could climb between 2.3°C and 2.8°C by century’s end, leaving vast regions uninhabitable through flooding, extreme heat, and ecosystem collapse. This trajectory creates significant stranded asset exposure for companies in fossil fuel extraction, carbon-intensive manufacturing, and climate-vulnerable real estate.
Key Valuation Drivers Emerging from COP 30
1. Enhanced Climate Disclosure Requirements
As of September 2025, approximately 100 countries have submitted or unveiled new Nationally Determined Contributions climate targets, though this represents only about half of the Paris Agreement signatories. The growing emphasis on transparency means companies will face stricter disclosure requirements around:
- Scope 1, 2, and 3 emissions
- Climate scenario analysis
- Transition plans with measurable milestones
- Physical climate risk assessments
Valuation professionals must incorporate these disclosure costs and the potential reputational impacts of climate performance into their analyses.
2. Adaptation Finance as a Growth Sector
The UN Environment Programme warns that adaptation finance must rise twelvefold by 2035 to meet developing countries’ needs. This creates substantial opportunities for companies in:
- Climate resilience infrastructure
- Water management technologies
- Sustainable agriculture solutions
- Early warning systems and climate modeling
- Green building materials and design
Companies positioned in adaptation-enabling sectors may command premium valuations due to regulatory tailwinds and assured demand growth.
3. Just Transition Obligations
COP30 is advancing the Just Transition Work Programme, aimed at ensuring climate measures don’t deepen inequality. This adds a new dimension to valuation considerations, particularly for companies in:
- Energy sector (transition away from fossil fuels)
- Heavy manufacturing
- Mining and extraction
- Transportation and logistics
Valuation professionals must assess the financial implications of worker retraining programs, community support initiatives, and potential regulatory requirements around equitable transition planning.
Sector-Specific Implications
Energy and Utilities
With Brazil hosting COP30 while simultaneously approving oil exploration in the Amazon, experts warn of risks to the rainforest and dangers of further entrenching the country in fossil fuels. This paradox highlights the complex transition dynamics affecting energy company valuations. Forward-looking valuations must account for:
- Accelerated depreciation of fossil fuel assets
- Capital requirements for renewable energy buildout
- Grid modernisation costs
- Energy storage investments
Real Estate and Infrastructure
Adaptation finance is not keeping pace with climate impacts, leaving vulnerable populations exposed to rising seas, deadly storms, and searing heat. Real estate and infrastructure assets require enhanced due diligence around:
- Physical climate risk exposure
- Insurance availability and cost
- Regulatory compliance with building standards
- Location-specific climate scenarios
Properties in high-risk zones may see valuations decline as insurance becomes prohibitively expensive or unavailable.
Agriculture and Food Systems
Family farming is gaining prominence at COP30, signaling potential support for sustainable agricultural practices. Companies investing in regenerative agriculture, precision farming, and climate-resilient crop varieties may benefit from policy support and consumer preference shifts.
Financial Services
Banks, insurers, and asset managers face dual pressures: managing climate risk in their portfolios while capturing opportunities in climate finance. Advancing climate finance, particularly for adaptation, is a central priority of COP30. Financial institutions with robust climate risk frameworks and green finance offerings may command valuation premiums.
Practical Recommendations for Valuation Professionals
1. Integrate Climate Scenarios into DCF Models
Move beyond single-point forecasts to scenario-based valuation incorporating:
- 1.5°C aligned scenario (aggressive climate action)
- 2°C scenario (moderate action, current pledges)
- 3°C+ scenario (limited action, high physical risk)
2. Enhance ESG Due Diligence
Climate considerations are no longer optional add-ons but core valuation drivers. Comprehensive due diligence should assess:
- Alignment with Paris Agreement goals
- Credibility of net-zero commitments
- Capital expenditure requirements for transition
- Supply chain climate dependencies
3. Monitor Emerging Adaptation Indicators
Negotiators at COP30 are finalising a list of indicators to measure progress toward the global goal on adaptation. Once established, these metrics will provide standardised benchmarks for assessing corporate climate preparedness and should be incorporated into valuation frameworks.
4. Assess Just Transition Liabilities
Quantify potential costs associated with worker transition, community support, and equitable phase-out of high-carbon activities. Companies with proactive just transition strategies may avoid regulatory penalties and reputational damage.
Looking Ahead: From Belém to Implementation
COP30 leadership says this year’s conference must be remembered as “the COP of implementation and adaptation”. For valuation professionals, this shift from pledges to action means:
- Regulatory risk is increasing for non-compliant companies/assets
- Competitive advantages are accruing to climate leaders
- Physical climate impacts will materially affect asset values
- Transition opportunities represent significant value creation potential
The coming months will reveal whether nations navigate on their COP30 commitments, but the direction of travel is clear: climate considerations are becoming central to valuation across all sectors.
Conclusion
COP30 in Belém represents a significant moment in global climate action, with implications extending far beyond environmental policy into the realm of corporate finance and valuation. As the world mobilises $1.3 trillion annually toward climate goals, valuators must evolve their methodologies to capture climate risks and opportunities.
The most successful valuation practices will be those that integrate climate scenarios into core models, understand sector-specific transition pathways, and can advise clients on positioning for a net-zero economy. With temperatures projected to rise significantly without urgent action, the time for valuation professionals to act is now/immediate.
Stay informed as COP30 negotiations unfold, and consider how emerging agreements will affect valuation assignments in the months and years ahead. The transition to a climate-resilient economy is not a distant future scenario—it’s reshaping asset values today.
