The Climate and Nature Economic Policy Scenarios (CNEPS) initiative develops forward-looking economic scenarios that integrate climate change, biodiversity loss and transition dynamics into macroeconomic policy analysis for Ministries of Finance and Public Development Banks (PDBs).
Co-designed with Ministries of Finance and PDBs, CNEPS aims at connecting global, regional and country-level perspectives to explore how geoeconomic, financial, technological and environmental transformations could reshape national economies, fiscal frameworks and development pathways and how countries could coordinate economic policy mixes and financing strategies in response.
Context
Ten years after the signing of the Paris Agreement, and five years into the Kunming-Montreal Agreement, he global economy is entering a period of profound structural change, often called “mid-transition”. Climate change, biodiversity loss, energy system transitions and shifting geopolitical dynamics are increasingly shaping economic development, financial stability and public finances. Climate shocks are already affecting fiscal balances and investment needs, while ecosystem degradation threatens key economic sectors such as agriculture, water and natural resources. At the same time, the transition toward low-carbon economies is transforming supply chains, trade relations and industrial strategies.
For Ministries of Finance, these dynamics are emerging as core macroeconomic risks while fostering new opportunities. Yet existing policy frameworks often struggle to integrate climate and nature fat-tailed risks (explication ou lien) into a systemic framework. Developing forward-looking economic scenarios that capture these interactions is therefore essential to support resilient fiscal planning and long-term development strategies.
It is in this context that AFD has launched the Climate and Nature Economic Policy Scenarios (CNEPS) initiative, a multilateral platform for the development of forward-looking economic scenarios to help policymakers anticipate these transformations and inform economic policy choices. It joins forces with an ecosystem of institutional, regional and academic partners to foster a shared language on plausible futures and related resilient economic policies.
Objective
The Climate and Nature Economic Policy Scenarios (CNEPS) initiative aims to develop forward-looking economic scenarios that help integrate climate change, biodiversity loss and transition dynamics into macroeconomic policy analysis. The project focuses on three main objectives:
- Technical integration: integrate climate and nature fat-tailed risks within macroeconomic policy frameworks, exploring nonlinear shocks, tipping points and geopolitical regime shifts, while building on existing structured country collaborations of AFD as well as regional and institutional partners.
- Policy interface: translate joint global scenarios into implications for fiscal policy, debt sustainability, industrial strategies and investment planning, while supporting champion countries in developing resilient national financing strategies.
- Coalition building: mobilise Ministries of Finance, Public Development Banks and academic partners, and connect existing finance-minister and public development banking platforms to scale impact and strengthen policy dialogue.
Method
The approach brings together global analytical work and country-level collaboration to explore how climate and nature risks, transition dynamics and geopolitical shifts could affect national economies and public finances.
The initiative builds on partnerships between research institutions, development finance actors and Ministries of Finance in participating countries. Academic partners contribute modelling expertise and scenario design, while Ministries of Finance and Public Development Banks provide policy perspectives and help identify the most relevant economic questions and applications.
The project mobilises an international knowledge network and works with partner countries to ensure that the scenarios developed respond to concrete policy needs and strengthen local analytical capacity.
For this project, AFD is partnering with the University of Exeter.
Expected results
The CNEPS initiative will deliver a first generation of forward-looking economic scenarios exploring how climate change, biodiversity loss and global transition dynamics could affect national economies and public finances.
Key outputs will include a first mid-transition analytical report presenting emerging global trends and systemic risks, as well as a first set of global scenarios developed with champion countries and regional partners. These scenarios will be translated into country-level assessments exploring implications for resilient fiscal policy, debt sustainability and investment strategies.
The project will also support participating countries in developing a first series of national CNEPS strategies aimed at informing resilient financing pathways and long-term economic planning.
Beyond analytical outputs, the initiative will contribute to policy dialogue and capacity strengthening through workshops, regional exchanges and engagement with international platforms bringing together Ministries of Finance and Public Development Banks.
Events
Several events were organized as part of the CNEPS Initiative :
On November 6th, 2026, in Istanbul, the OECD’s Clean Energy Finance and Investment Mobilisation programme (CEFIM) and the Country Platforms Hub held a high-level roundtable on country platforms, in the lead-up to COP31. It brought together policymakers, development finance institutions, institutional investors, industry associations, civil society, academia and country platform experts. Participants shared practical lessons from existing platforms and discussed governance, tools and financing strategies to help emerging markets and developing countries accelerate investment in their domestic priorities, such as clean energy and green industrialisation. The event marked the launch of criteria for effective country platforms, alongside key steps for investment mobilisation. AFD contributed to the discussions, bringing scenario-based analysis to inform how countries can define and sequence their investment pathways.
On 10 and 11 October 2026, the International Centre for Interdisciplinary Science and Education (ICISE) hosted the founding edition of the Quy Nhon Dialogue on Climate and Transitions, developed by Rencontres du Vietnam with the support of the Agence Française de Développement (AFD) as founding partner, under the high patronage of the Vietnamese Ministry of Science and Technology and the People’s Committee of Gia Lai Province. Held under the theme “Transitions Under Pressure: Energy Security, Financial Transformation and Climate Resilience”, this founding edition brought together over 80 policymakers, scientific experts and representatives of financial institutions from Vietnam, Southeast Asia and beyond, alternating high-level plenary sessions and technical parallel sessions in smaller groups. Based on this inaugural edition, Dialogue aims to transform the tensions of this second decade of the Paris Agreement into concrete opportunities, through direct peer-to-peer exchanges, the sharing of country experiences, and science-informed debate.
This roundtable explored how finance ministries and public development banks can integrate climate and nature-related systemic risks into macroeconomic and fiscal decision-making. Building on recent advances in climate-economy modelling, the discussion examined the limitations of conventional equilibrium-based approaches and the need for scenario frameworks that incorporate non-linearity, uncertainty, and ecological tipping points. The event aimed to identify practical pathways for developing more policy-relevant and user-centered scenarios, co-produced with public financial institutions to support resilient and forward-looking economic planning ahead of Climate Forum 2026.
A French Development Agency (AFD), Finance in Common (FiCS), International Development Finance Club (IDFC), UCL Institute for Global Prosperity (IGP) and The New Alignment (TNA) roundtable on Ministries of Finance, Public Development Banks and the incoming COP31 and UK G20 Presidency. The event explores how Climate and Nature Economic Policy Scenarios (CNEPS) can help Ministries of Finance and Public Development Banks coordinate around country platforms and other country-led investment frameworks to accelerate implementation in a turbulent mid-transition context.
In an increasingly fragmented geopolitical landscape, this one-day conference co-organized by AFD and the Energy Institute of University of Texas (Austin) in Paris convenes leading academics, policymakers and philanthropies to address a critical blind spot in global climate policy debates: the interactions between the transformation of energy systems and geopolitical shifts.
Across four sessions, the conference will explore why existing economic frameworks—often built on assumptions of global cooperation, free trade, and exogenous growth unrelated to energy use—fail to account for rising tensions and the non-linear risks associated with stranded assets and energy costs:
- Session 1: Understanding the role of energy in economic transitions: lessons from the 1970s to today
- Session 2: The geoeconomic turn of the energy transition: energy security, energy affordability and energy imperialism.
- Session 3: The macrofinancial turn of the energy transition: stranded assets, cost of capital and balance of payment instabilities
- Session 4: Building scenarios for the mid-transition period: what can the models tell us?
Dans un contexte géopolitique de plus en plus fragmenté, cette conférence d’une journée, co-organisée par l’AFD et l’Energy Institute de l’Université du Texas (Austin) à Paris, réunit des universitaires de premier plan, des décideurs politiques et des organisations philanthropiques pour aborder un angle mort critique dans les débats mondiaux sur la politique climatique : les interactions entre la transformation des systèmes énergétiques et les mutations géopolitiques.
Paris 20 March 2026- Agence Française de Développement (AFD) and the University of Exeter signed a Memorandum of Understanding at the British Embassy in Paris to strengthen collaboration on climate and nature economic policy analysis for Ministries of Finance and Public Development Banks.
This workshop convened over 240 participants, including representatives from Ministries of Finance, central banks, financial supervisors, public development banks, ministries of environment and development co-operation, research institutes, and academia. The event comprised a technical workshop in the morning and high-level sessions in the afternoon, both held under the Chatham House rule.
