2050 is now: Aligning climate action with long-term climate and development goals

This project will provide governments and in-country research institutes and other relevant stakeholders with tools and analysis to strengthen Long-term strategies on the mitigation of greenhouse gases (LTS) with a strong focus on energy and land-use and food systems, in line with national development goals. Therefore the project will help to align short- and medium-term sectoral, economic and national development plans with LTS, including supporting a just transition. This includes to identify opportunities to enhance Nationally Determined Contributions (NDCs), on the basis of LTS, while achieving development goals…


The IMAGINE project aims to enhance the 2023 Global Stocktake by synthesizing existing knowledge and generating new assessments. It seeks to accelerate climate action at national and global levels by improving modeling capacity in seven countries, crafting transformative national scenarios, and engaging policymakers. The project involves 14 institutions, collaborating on modeling, policy expertise, and international teamwork. The project, funded by the European Commission, is led by IDDRI and includes institutions like Climate Analytics, CIRED, GAEL, BC3, and SDSN.

Deep Decarbonization Pathways in Africa 

The DDP-Africa initiative is a national research and capacity building project for the implementation of a Deep Decarbonization Pathway (DDP) Programme in Africa, coordinated by IDDRI. It is developed under the framework of the 2050 Facility funded by the Agence Française de Dévelopment (AFD) and currently operates in Nigeria and Senegal.
It is supported by the Federal Ministry of Environment (Nigeria) and the Ministry of Environment and Sustainable Development and by the Ministry of Petroleum and of the Energy (Senegal).


This project, which is conducted with teams from Brazil and Mexico in collaboration with ACT – Assessing Low-Carbon Transition, aims at developing a methodology to build, evaluate and monitor decarbonisation strategies at the company level.

ACT is a joint initiative of the Carbon Disclosure Project and of the French Energy Agency (ADEME). The DDP ACT project it is supported by the French Fund for the Global Environment (FFEM).

NDC Aspects

The Paris Agreement’s Global Stocktake (GST) reviews progress every five years, guiding Nationally Determined Contributions (NDCs). NDC ASPECTS focuses on key sectors like transport, industry, buildings, and agriculture, aiming to enhance gender-responsive NDC revisions. Through Sectoral Conversations, it collaborates with experts to create evidence-based narratives, informing global and national pathways for strategic countries. The project assesses transformation challenges, emphasizing societal, economic, political, and environmental aspects, and aims to improve international governance for sectoral climate neutrality and Sustainable Development Goals attainment.


This project, conducted with research teams from five major emerging economies aims at developing decarbonisation pathways for key sectors in Brazil, China India, Indonesia and South Africa, and to stimulate public debate on this basis.
It is supported by the International Climate Initiative (IKI) of the German Government.


This project aims at equipping in-country teams in Argentina, Colombia, Costa Rica, Equateur, Mexico and Peru with tools and methodologies for the elaboration of decarbonisation pathways. Based on the expanded capacity, the secondary objective is to initiate and facilitate exchange of knowledge between researchers and decision-makers, so that the conclusions of long-term analysis are embraced in short-term policy, including in the revision of NDCs.
It is supported by the Inter-American Development Bank (IDB), the Agence Française de Développement (AFD) and the 2050 Pathways Platform.

DDP Transport

The first phase of this project focused on passenger mobility in France, Japan, Mexico and the United Kingdom. The pathways developed by the DDP research teams, as well as the pathway building tool resulting from their work, are already available on this website in beta version.
A second phase of the project is underway. It extends the approach to freight transport and to three new countries: China, India and South Africa.

This work has been presented in different fora, with other major international initiatives for the sector: Decarbonising Transport initiative led by ITF-OECD, Science Based Targets led by WWF, WRI, CDP and UNGC, Sustainable Urban Mobility led by WBCSD and the Global Macro Roadmap for Transport Decarbonisation led by PPMC.
It is supported by the Michelin Corporate Foundation and by IDDRI.
