AD-MERGE 2.0: an integrated assessment of the Nexus among energy transitions, climate impacts, and adaptation responses

This paper presents AD-MERGE 2.0, an enhanced integrated assessment model that evaluates reactive (“flow”) and proactive (“stock”) adaptation strategies along with climate mitigation policies.

Decarbonization potential and limits of e-fuel policies in the EU

E-fuels (i.e., hydrogen synfuels derived from electrolysis and carbon capture) are increasingly viewed as strategic enablers to the European Union’s (EU) energy transition, offering potential decarbonization pathways for hard-to-abate sectors.

Climate leadership in the Global South: insights from Ecuador and Brazil’s NDC submissions

Despite major implementation gaps in both countries, the experience of Ecuador and Brazil identifies six factors that enable the successful formulation and timely submission of updated NDCs in the Global South.

Including ozone increases estimated global crop and economic benefits of carbon neutrality policies

A new modelling study published in Nature Food “Including ozone increases estimated global crop and economic benefits of carbon neutrality policies” reveals that carbon‑neutrality policies deliver larger agricultural and economic benefits once tropospheric ozone impacts are fully incorporated into integrated assessment frameworks.

A provincial-level modeling framework for integrated building stock-energy-material-carbon assessment in China

Most building decarbonisation plans ignore how building stocks age and get replaced. MESSAGEix-China-Building-R31 links stock, energy, materials and emissions across 31 Chinese provinces to 2100, so it can map low-carbon pathways for each province.

Different dimensions, different vulnerabilities: Intersectional energy poverty in India

A new paper in Energy Research & Social Science examines how overlapping social and economic disadvantages shape different dimensions of energy poverty in India.

Modeling justice without deciding it

A new Perspective in Energy Research & Social Science uses social-choice theory to examine this question across welfare-based and process-based IAM applications.

Self-defined progression and the limits of the Paris ratchet

Under Article 4.3 of the Paris Agreement, each new NDC must go further than the last, but the Agreement leaves it to each Party to decide how that progression is measured.

FUTURA: Future of Climate Change Scenarios of the Earth System, Impacts and Socio-Economic Outcomes for Assessment and AND Society

For the first time, one project brings together Europe's major modelling efforts to deliver emissions and land-use scenarios and climate and impact projections through a single, sustainable system.

CMCC Talk: Artificial societies, real decisions: agent-based simulation for climate policy testing

How might we assess whether a climate adaptation policy will benefit a population — and at what economic cost — before it is implemented? In this talk, Alessandro Taberna (CMCC) presents a bottom-up, data-intensive approach based on agent-based simulation.

CMCC Lecture: Generative AI for climate and weather

Generative AI gives climate scientists new ways to work with large, complex and heterogeneous climate data. In this CMCC Lecture, Prof. Claire Monteleoni (INRIA Paris and University of Colorado Boulder) looks at where generative AI and climate science meet.
