1. Solution Title

Transition national economic governance from neoclassical frameworks to biophysical and ecological economic systems that recognise planetary limits and energy constraints.

2. Step-by-Step Implementation Guide

This guide outlines a sequenced, multi-year strategy for a national government to fundamentally reform its economic governance framework, moving from neoclassical models that systematically underestimate ecological risk to a biophysical and ecological economics approach that recognises planetary limits, energy constraints, and the primacy of long-term resilience over short-term GDP growth.

Step 1 – Conduct a Comprehensive Audit of Existing Economic Models and Forecasts

  • Action: Commission an independent, cross-disciplinary review (via the national statistics office, treasury, central bank, and an external panel of ecological economists, biophysicists, and climate scientists) to audit all major economic models and forecasts used for policymaking.
  • Responsible Actor: National Statistics Office / Ministry of Finance / Central Bank / Independent Science Panel.
  • Completion Looks Like: A published report that:
    • Identifies all neoclassical assumptions embedded in current models (e.g., smooth damage functions, exclusion of energy as a primary input, cross-sectional temperature-GDP relationships).
    • Assesses the divergence between economic forecasts and scientific warnings on climate, biodiversity, and resource depletion.
    • Quantifies the gap between official GDP projections and biophysical reality (e.g., energy return on investment – EROI, material throughput, carbon budgets).

Step 2 – Reform National Accounting (GDP) to Include Biophysical and Ecological Metrics

  • Action: Revise the System of National Accounts (SNA) to move beyond GDP as the primary measure of progress, incorporating biophysical and ecological indicators.
  • Responsible Actor: National Statistics Office, with input from ecological economists and natural scientists.
  • Completion Looks Like:
    • Adoption of a “Comprehensive Wealth” framework that accounts for natural capital depreciation (e.g., loss of biodiversity, soil degradation, resource depletion) alongside produced and human capital.
    • Introduction of a “Genuine Progress Indicator” (GPI) or “Index of Sustainable Economic Welfare” (ISEW) as a co-primary metric alongside GDP.
    • Mandatory national reporting on energy throughput, material flows, and carbon emissions as core economic indicators.
    • Reclassification of energy as a primary factor of production (alongside labour and capital) in national accounting, acknowledging that “labour without energy is a corpse; capital without energy is a sculpture.”

Step 3 – Replace Neoclassical Damage Functions with Biophysical Climate-Economic Models

  • Action: Abandon the use of neoclassical Integrated Assessment Models (IAMs) with quadratic damage functions (e.g., DICE, PAGE, FUND) for climate policy analysis, replacing them with models grounded in biophysical reality and ecological dynamics.
  • Responsible Actor: Ministry of Finance / Treasury / Climate Change Authority / Central Bank.
  • Completion Looks Like:
    • Phasing out DICE, PAGE, and FUND-based forecasts for all official climate policy analysis.
    • Adoption of models that explicitly include:
      • Energy as a primary production input (with EROI analysis).
      • Non-linear, threshold-based damage functions (reflecting tipping points and cascading effects).
      • Climate-economy feedback loops (e.g., loss of labour productivity in outdoor sectors, infrastructure damage, supply chain disruption).
      • The economic impact of “Hothouse Earth” scenarios (e.g., 4°C+ warming, mass migration, agricultural collapse).
    • Independent peer review of all models by natural scientists and ecological economists before use in policy.

Step 4 – Establish a National “Energy and Resilience” Investment Framework

  • Action: Create a new national investment framework that prioritises energy efficiency, renewable energy transition, and resilience-building, recognising that fossil fuel dependency is the core driver of both climate change and economic vulnerability.
  • Responsible Actor: Ministry of Energy / Ministry of Infrastructure / National Investment Bank.
  • Completion Looks Like:
    • A national “Energy Transition and Resilience Plan” with binding targets for:
      • Reduction in fossil fuel energy production and consumption.
      • Increase in renewable energy capacity, storage, and grid resilience.
      • Improvement in national EROI (Energy Return on Investment) for key sectors.
      • Reduction in material throughput (circular economy targets).
    • A “Green New Deal”-style investment programme funded by redirected subsidies, a carbon tax, and a financial transaction tax.
    • Mandatory EROI and energy-lifecycle analysis for all major infrastructure and industrial projects.

Step 5 – Reform Financial Regulation to Account for Climate and Ecological Risk

  • Action: Mandate that all financial institutions (banks, pension funds, insurance companies, asset managers) assess and disclose their exposure to climate and ecological risk using biophysical metrics, not just neoclassical probability models.
  • Responsible Actor: Financial Regulator / Central Bank / Ministry of Finance.
  • Completion Looks Like:
    • Introduction of mandatory “Climate and Ecological Stress Tests” for all major financial institutions, using scenarios that include:
      • 3°C, 4°C, and 5°C+ warming pathways.
      • Tipping point cascades (e.g., permafrost melt, Amazon dieback, ice sheet collapse).
      • Rapid devaluation of fossil fuel assets (“stranded assets”).
      • Mass migration and supply chain disruption.
    • Divestment mandates for public pension funds from fossil fuels and other high-extraction industries.
    • Risk-weighting of assets to reflect ecological vulnerability (e.g., fossil fuels, carbon-intensive agriculture, coastal real estate).
    • A “climate capital adequacy” requirement for banks, similar to Basel III capital requirements.

Step 6 – Overhaul Public Procurement and Infrastructure Planning to Prioritise Resilience

  • Action: Reform all government procurement and infrastructure planning to prioritise long-term resilience, energy efficiency, and ecological sustainability over short-term cost savings.
  • Responsible Actor: Ministry of Finance / Cabinet Office / National Audit Office.
  • Completion Looks Like:
    • All major infrastructure projects (energy, transport, water, coastal defence) are assessed using a “Resilience and Energy Return” framework, not just cost-benefit analysis.
    • Procurement criteria favour local, low-carbon, low-material-intensity solutions.
    • All publicly funded projects are required to meet net-zero and circular economy standards by 2030.
    • Phasing out of fossil fuel subsidies and redirection of funds to renewable energy and energy efficiency programmes.

Step 7 – Establish a National “Ecological Economics” Research and Training Programme

  • Action: Invest in building national capacity in ecological economics and biophysical modelling across government, universities, and the private sector.
  • Responsible Actor: Ministry of Education / Ministry of Research and Innovation / Universities.
  • Completion Looks Like:
    • Creation of a national “Centre for Ecological Economics and Biophysical Modelling” with a multi-decade mandate.
    • Mandatory training for all civil servants, policymakers, and financial regulators in ecological economics principles.
    • Revision of university economics curricula to include biophysical, ecological, and post-Keynesian approaches alongside neoclassical theory (moving beyond “Economics 101”).
    • A national fellowship programme to attract scientists, engineers, and heterodox economists into public service.

Step 8 – Rebuild Public Confidence and Democratic Participation in Economic Governance

  • Action: Launch a national dialogue and participatory process to build public understanding of ecological limits and to co-create a new economic vision centred on resilience, sustainability, and well-being.
  • Responsible Actor: Government Communications Office / Civil Society Organisations / Media.
  • Completion Looks Like:
    • A national “Citizens’ Assembly on the Future of the Economy” to deliberate on the transition to an ecological economy.
    • A public information campaign explaining the biophysical basis of economic activity and the urgent need for change.
    • Development of new economic narratives in media and education that move beyond GDP fetishism and embrace planetary stewardship.

3. Polycrisis Strand(s)

Primary strand: Climate change
Interaction effects with other strands:

  • Energy and mineral resources: The solution explicitly addresses the fossil fuel dependency of the global economy and the need for a just transition to renewable energy.
  • Biodiversity loss: It recognises that economic activity is a primary driver of biodiversity loss and proposes reforms to account for natural capital.
  • Pollution, toxics and waste: It aligns with the goal of a circular economy and reduction of material throughput.
  • Inequality: The transition to an ecological economy must be managed to ensure a “just transition” that does not disproportionately harm vulnerable populations.
  • Food, health and disease: It acknowledges the impacts of climate change on agricultural productivity and human health.
  • Governance, peace and conflict: It addresses the systemic failure of neoclassical economics to inform sound policy and rebuilds public trust in governance.
  • Globalisation and finance: It proposes reforms to financial regulation to account for climate and ecological risk.

4. Scale Category

Notes on scale interaction: “Requires a strong national-level framework to enable change at all lower scales. A single nation’s transition may be undermined by global economic dynamics (e.g., trade in fossil fuels) without international coordination, but national leadership is essential to demonstrate feasibility and build momentum.”

5. Dewey Decimal Classification

Primary DDC: 333.7 – Natural resources, energy, and environment
Secondary DDC(s): 330.9 – Economic history and conditions; 333.72 – Conservation and protection; 338.927 – Sustainable development; 363.7 – Environmental problems; 577 – Ecology; 530 – Physics (for biophysical modelling)
Subject headings (LC or local): “Ecological economics”, “Biophysical economics”, “Climate change – economic aspects”, “Sustainable development”, “Energy policy”, “Natural capital”, “Post-Keynesian economics”, “Heterodox economics”

6. Regional Applicability

Evidenced implementations:

  • Bhutan (Gross National Happiness): A partial precedent for moving beyond GDP.
  • New Zealand (Wellbeing Budget): A recent example of a government adopting well-being metrics alongside GDP.
  • Costa Rica (Decarbonisation): A precedent for rapid transition to renewable energy.
  • Various (Climate litigation): Growing legal challenges to inadequate climate policy based on scientific evidence.
  • US (New Deal, Apollo programme): Historical examples of ambitious, mission-oriented public investment.

Climatic/geographic scope: [ ] Tropical [ ] Temperate [ ] Arid [ ] Arctic/sub-arctic [ ] Coastal [x] All
Political economy prerequisites: “Requires a functioning state with rule of law, independent judiciary, and a relatively stable political system capable of enacting and enforcing financial and environmental regulations. Requires a strong scientific community and a public that can be mobilised around ecological issues.”

Contraindications: “May be difficult to implement in contexts with high state capture, weak institutional capacity, heavy dependence on fossil fuel exports, or a highly concentrated financial sector. Opposition from entrenched fossil fuel and neoclassical interests is likely to be intense.”

7. Cost Estimate

Cost tierIndicative rangeBasis
Pilot / proof of concept£10 million – £100 millionCost of establishing the audit task force, reforming national accounts, and setting up the national ecological economics centre.
Community-scale deployment£100 million – £1 billionCost of regional pilot projects (e.g., energy transition, circular economy).
City/regional scale£1 billion – £10 billionCost of implementing the Energy Transition Plan and infrastructure reforms in a major region.
National rollout£100 billion – £1 trillion+Cost of a full national energy transition (e.g., decarbonising the electricity grid, transport, and industry; retrofitting buildings; building climate resilience).

Cost notes: “This is a national investment strategy, not a traditional ‘cost.’ The resources required are already in the economy but are currently directed towards fossil fuels and extractive industries. The transition will involve significant upfront investment but will generate long-term savings (e.g., reduced energy imports, avoided climate damages, improved health outcomes). The cost of inaction (unabated climate change) is likely to be orders of magnitude higher.”

Funding mechanisms used in existing implementations: “Carbon taxes, financial transaction taxes, redirected fossil fuel subsidies, green bonds (sovereign and municipal), and reallocation of existing budget lines from fossil fuel subsidies to renewable energy and resilience.”

8. Timescale Estimate

Time to initial implementation: 12-24 months (for the audit, accounting reform, and establishment of the national centre).
Time to measurable impact: 3-5 years (to see first effects on investment patterns, emissions, and resilience).
Time horizon of full benefit: 10-30 years (to complete the energy transition and see systemic benefits in terms of climate stability, resource security, and well-being).
Short-term vs long-term tension note: “This is a generational project requiring political will to overcome short-term vested interests. The short term will involve significant investment and potentially higher energy costs; the long-term benefit is the survival of a habitable planet and a sustainable economy. The ‘sacrifice’ is the profits of incumbent fossil fuel and extractive industries, not the well-being of the population.”

    Known counter-evidence or limitations: “This is a fundamental critique of the dominant paradigm. The theoretical case is strong, but the political feasibility of a full transition is the main limitation. There is a real risk of ‘regulatory capture’ by incumbent industries and neoclassical economists. The evidence base for alternative models (biophysical, ecological) is growing but is still less developed and less accepted in mainstream policy circles. The primary counter-argument from neoclassicals is that markets can adapt and that technological innovation will solve the problem, but this is based on the same faulty assumptions being critiqued.”
