The Economics of Climate Change

Slide 1: The Economics of Climate Change

From Crisis Cost to Transition Opportunity: Exploring Carbon Pricing, Green Investments, Inaction Costs, and Systemic Transition Risks

Slide 2: Contents

1. Carbon Pricing Mechanisms: Market-based instruments including emissions trading systems and carbon taxes driving emissions reduction across 28% of global emissions.
2. Green Technology Investments: Analysis of $2+ trillion annual capital flows reshaping energy systems, transportation, and industrial processes through clean technology deployment.
3. Cost of Inaction: Economic impacts of climate change including GDP losses, disaster costs, and long-term damage from unmitigated warming scenarios.
4. Transition Risks Assessment: Physical climate impacts and financial system vulnerabilities as economies shift from high-carbon to low-carbon production systems.

Slide 3: The Economic Context: Climate Change as Systemic Risk

1. $145B — Annual Insured Disaster Losses (2025)
2. 1.4°C — Average Warming Past 3 Years
3. 10-30% — GDP Loss at 3°C Warming
4. 12 — Warmest Years on Record (consecutive)

2025 insured losses from climate disasters reached $145 billion, up 6% from 2024. Global temperatures were second-hottest on record despite La Niña cooling. Economic modeling shows 3°C warming could reduce global GDP by 10-30%. Climate change has transitioned from an environmental issue to a systemic economic risk requiring immediate policy response.

Slide 4: Part I: Carbon Pricing

Market mechanisms driving global emissions reduction

Slide 5: Carbon Pricing: 28% of Global Emissions Covered

1. Emissions Trading Systems: Cap-and-trade mechanisms limiting total emissions while allowing market to set price. Major systems: EU ETS (world's largest), China national ETS, California-Quebec linkage. Covers power, industry, aviation sectors with declining emission caps driving transformation.
2. Carbon Taxes: Direct price per ton CO2e implemented in 35+ jurisdictions. Rates range from $5-140 per ton. Revenue recycling funds clean energy, adaptation, or tax reductions. Provides price certainty and administrative simplicity compared to trading systems.
3. Global Coverage Expansion: 28% of global emissions now carry a price signal, representing jurisdictions with two-thirds of global GDP. Hybrid approaches combining both mechanisms gaining traction in 2025-2026. International linkages emerging to harmonize cross-border pricing.

Slide 6: Carbon Pricing Effectiveness: Revenue and Impact

1. Revenue Mobilization: Global carbon pricing revenues exceeded $100 billion in 2024, funding climate adaptation, mitigation programs, and just transition support. Power sector shows highest coverage at over 50% of emissions.
2. Quality Premium Emerging: High-integrity carbon credits trade at $35+ versus $20 for lower-rated equivalents. Compliance and voluntary markets converging through ICVCM Core Carbon Principles framework, driving market sophistication.

Comparison of sectoral coverage under carbon pricing mechanisms between 2020 and projected 2025. Power generation shows the largest increase in coverage.

Slide 7: Part II: Green Technology Investments

3. 35M — Global Clean Energy Jobs
4. $1.9T — China Clean Energy Market (2024)

Clean energy investments surpassed $2 trillion annually in 2024-2025, outpacing fossil fuel investment for the first time. China leads with clean energy contributing 10% of GDP, dominating solar, EV, and battery markets. Global employment in clean energy sector reached 35 million, exceeding fossil fuel employment. Investment patterns shifting from early-stage speculative ventures to later-stage scalable solutions with proven business models and clear commercialization pathways.

Slide 9: Green Technology Sector Impact

1. Power Generation: Solar and wind now cost-competitive with fossil fuels in most markets. Rapid deployment enabled by technology maturity and economies of scale. Grid integration challenges driving energy storage innovation.
2. Transportation Electrification: EV market expansion with infrastructure investment creating new value chains. Battery technology breakthroughs reducing costs while improving range. Heavy transport and aviation pursuing hydrogen and synthetic fuel alternatives.
3. Industrial Decarbonization: Advanced materials, process innovations, and carbon capture gaining traction. Green hydrogen post-hype rationalization focusing on hard-to-abate sectors. Steel, cement, and chemicals leading transformation efforts.
4. Agriculture and Land Use: Precision agriculture and regenerative practices reducing emissions while increasing productivity. Satellite monitoring, IoT sensors, and AI optimizing resource use. Nature-based solutions providing carbon sequestration co-benefits.
5. Energy Storage and Grid Modernization: Battery technology breakthroughs addressing intermittency challenges. Grid upgrades managing demand surges from AI and data centers. Distributed energy resources and smart grid technologies enhancing resilience.

Slide 10: Part III: Cost of Inaction

Economic losses escalating faster than mitigation costs

Slide 11: Cost of Inaction: Escalating Economic Losses

GDP modeling: 3°C warming projects 10-30% global GDP decline under unmitigated climate change scenarios

Annual disaster costs: $145B insured losses in 2025, with actual economic damage 3-4x higher including uninsured losses

Sectoral vulnerabilities: Agriculture, coastal infrastructure, water resources, and supply chains face mounting disruption costs

Regional disparities: Developing economies bear disproportionate burden with limited adaptive capacity and financial resources

Tipping point risks: Irreversible damages beyond 2°C warming carry exponential cost escalation including ecosystem collapse

Slide 14: Financial System Exposure to Climate Risks

Central banks and financial regulators increasingly identify climate risk as systemic threat to financial stability. Stranded asset estimates range from $1-4 trillion in fossil fuel infrastructure at risk of premature write-downs. Portfolio analysis for 2026 shows physical and transition risks now represent material factors for institutional investors requiring stress testing and scenario analysis.
