Integrated Assessment Models

IAMs couple physical climate system models with economic frameworks to evaluate long-run mitigation and adaptation pathways. The defining feature is the endogenous interaction between socioeconomic drivers, emissions, climate response, and economic feedback — producing normative (cost-minimising) or descriptive scenarios. IAMs range from highly stylised (Ramsey-type, e.g. DICE) to detailed process-based models (e.g. MESSAGE, REMIND, GCAM).

BOUNDARY: IAMs do not estimate present-day damages (→ Area 2), do not price carbon instruments (→ Area 5), and do not address NDC commitments directly (→ Area 8). The focus is the computational architecture of climate-economy interaction and scenario construction.
Dominant paradigms
Cost-benefit IAMs (Nordhaus/DICE tradition) vs cost-effectiveness IAMs (optimal pathway models). The field is currently split between these two normative framings, with increasing integration of Earth system tipping points.
Frontier debates
Discount rate choice (Weitzman vs Nordhaus); representation of inequality and distributional effects; integration of financial system dynamics; handling of deep uncertainty and fat-tailed risks.

Economic Impacts of Climate Change

Empirical and theoretical analysis of how climate change (temperatures, precipitation, extreme events) affects economic outcomes — GDP growth, agricultural productivity, labour supply, conflict, health, and inequality — in the present and under future scenarios. This area is defined by the econometric identification of climate effects using observational data.

BOUNDARY: Distinct from IAMs (→ Area 1), which use stylised damage functions. Distinct from non-market valuation (→ Area 3), which monetises specific ecosystem or welfare effects. The focus here is macroeconomic and sectoral impact estimation from empirical data.
Key methodological debates
Linear vs nonlinear temperature-income relationships; long-run vs short-run adaptation; global vs heterogeneous impacts; projection of historical relationships to future warming levels.
Frontier
Integration of financial market channels; general equilibrium effects of climate shocks; distributional impacts within countries; compound risk events.

Non-Market Valuation

Methods and applications for assigning monetary values to goods and services not traded in markets — principally ecosystem services, biodiversity, human health, and statistical life. Encompasses revealed preference methods (hedonic pricing, travel cost), stated preference methods (contingent valuation, choice experiments), and the estimation of the Social Cost of Carbon (SCC).

BOUNDARY: Provides the damage valuation inputs that feed into IAMs (→ Area 1) and cost-benefit analyses of carbon pricing (→ Area 5). Does not address aggregate macroeconomic impacts (→ Area 2) nor financial market effects (→ Area 7). Core disciplinary home is environmental and welfare economics.
Key debates
Validity of stated preference methods under hypothetical bias; discount rate for intergenerational welfare; equity weighting; treatment of mortality risk across income groups; scope of non-market damages in SCC estimation.
Frontier
Comprehensive SCC estimates incorporating omitted damage categories; distributional weighting of climate damages; valuation of tipping points and irreversibility; machine learning for preference estimation.

Climate Finance

The mobilisation, tracking, attribution, and effectiveness of financial flows — public and private — directed at climate change mitigation and adaptation. Covers MRV of climate finance, concessional finance instruments, blended finance, multilateral development bank flows, and the emerging architecture of the global climate finance goal (NCQG).

BOUNDARY: Distinct from carbon pricing (→ Area 5), which uses market instruments to internalise externalities. Distinct from climate macroeconomics (→ Area 7), which analyses systemic financial risk. Climate finance here refers to the dedicated finance flows tracked under the UNFCCC framework and in development finance.
Key debates
Definition and attribution of "climate finance"; additionality vs double-counting; private finance mobilisation ratios; grant vs loan instruments for LDCs; adequacy of the $100bn goal and the NCQG.
Frontier
Debt sustainability and climate finance in highly indebted countries; just transition finance; measuring adaptation finance effectiveness; sovereign sustainability-linked bonds.

Carbon Pricing & Markets

The design, implementation, and evaluation of market-based instruments for reducing greenhouse gas emissions — principally carbon taxes, cap-and-trade systems (ETS), and voluntary carbon markets. Covers the theoretical foundations of environmental market design, the political economy of carbon pricing, and the empirical performance of existing schemes (EU ETS, RGGI, California).

BOUNDARY: Distinct from climate finance (→ Area 4), which covers dedicated finance flows. Distinct from policy design (→ Area 8), which addresses the broader NDC architecture. The focus here is specifically on price-based instruments and their market functioning.
Key theoretical debates
Prices vs quantities (Weitzman 1974) under uncertainty; revenue recycling and distributional effects; carbon border adjustments; credibility and political economy of carbon price trajectories; interaction with complementary policies.
Frontier
CBAM design and WTO compatibility; integrity of voluntary carbon markets; carbon price alignment across jurisdictions; second-best interactions with energy subsidies; carbon price credibility under political uncertainty.

Loss & Damage Economics

Economic analysis of climate-related losses and damages that cannot be avoided through mitigation or adaptation — encompassing attribution science, liability frameworks, compensation mechanisms, insurance, and the new Loss and Damage Fund established at COP27. A rapidly growing field at the intersection of economics, law, and climate science.

BOUNDARY: L&D is distinct from adaptation economics — adaptation addresses avoidable impacts, L&D addresses residual unavoidable impacts. Distinct from the aggregate macroeconomic impacts literature (→ Area 2), which estimates total damages under warming scenarios. L&D focuses on attribution, liability, and compensation for specific events and slow-onset processes.
Key debates
Attribution of individual extreme events to anthropogenic climate change; the liability-compensation distinction; non-economic losses (culture, identity, sense of place); additionality and conditionality of L&D finance; WIM vs formal compensation frameworks.
Frontier
Operationalisation of the Santiago Network; design of the L&D Fund after COP28; slow-onset event attribution; economic frameworks for non-economic losses; sovereign risk transfer instruments for vulnerable countries.

Climate Macroeconomics

The macroeconomic and financial system dimensions of climate change and the low-carbon transition — including systemic financial risk from climate physical and transition shocks, stranded assets, green monetary and fiscal policy, innovation dynamics, and the macroeconomic effects of decarbonisation on growth, employment, and financial stability.

BOUNDARY: Distinct from microeconomic impact estimation (→ Area 2). Distinct from carbon pricing instruments (→ Area 5). Distinct from dedicated climate finance flows (→ Area 4). The defining focus is systemic: how does climate change interact with macroeconomic dynamics, business cycles, financial stability, and technical change?
Key debates
Magnitude of climate-related financial risk vs standard market risk; effectiveness of green monetary policy; directed technical change towards low-carbon technologies; macroprudential regulation of climate risk; fiscal space for green investment.
Frontier

Climate Policy Design & NDC Economics

The design, evaluation, and strengthening of national climate policies within the Paris Agreement framework — focusing on the economics of Nationally Determined Contributions (NDCs): ambition assessment, macroeconomic consistency, sectoral decomposition, fairness metrics, and the relationship between pledges and long-term net-zero pathways.

BOUNDARY: Distinct from IAMs (→ Area 1), which generate the scenarios NDCs are measured against. Distinct from carbon pricing (→ Area 5), which is one instrument within NDC policy mixes. The defining focus is the political-economy and institutional architecture of the Paris Agreement's NDC cycle, and what makes a good NDC economically.
Key debates
Fairness and equity in NDC ambition (CBDR-RC); aggregate insufficiency of current NDCs; conditionality of climate finance on NDC implementation; sectoral coverage; link between NDCs and long-term strategies (LTS).
