ACCLIMATE at COP31
As world leaders, policymakers and climate experts gather in Antalya, Türkiye, for the 31st UN Climate Change Conference (COP31), ACCLIMATE partners will contribute to discussions on international climate cooperation, the implementation of national climate commitments and the transition towards net-zero emissions.
From 11 to 13 November 2026, ACCLIMATE partners IDDRI and the Wuppertal Institute for Climate, Environment and Energy will participate in three events addressing key challenges for international climate action, from preparations for the second Global Stocktake (GST2) to aligning Nationally Determined Contributions (NDCs) with long-term climate strategies.
These discussions are closely connected to ACCLIMATE's objectives of strengthening national and international climate strategies, assessing the adequacy, feasibility and fairness of climate commitments, and supporting the implementation of the Paris Agreement.
11 November | The Road to the Second Global Stocktake (GST2)
Time: 15:00–16:30
Location: Side Event Room 8 – BERGAMA, COP31, Antalya
ACCLIMATE partners IDDRI and the Wuppertal Institute will contribute to the official UN Climate Change side event “The Road to the Second Global Stocktake (GST2)”, alongside international climate organisations.
As COP31 launches the second Global Stocktake, the event will reflect on lessons learned from the first stocktake (GST1) and explore how the next process can strengthen international cooperation, accelerate climate action and support the implementation of the Paris Agreement. Speakers will share experiences and examine how the GST2 process can deliver ambitious and equitable outcomes.
Anna Pérez Català from IDDRI and Wolfgang Obergassel from the Wuppertal Institute will contribute to the discussion. They will share findings from ACCLIMATE’s research on how the first Global Stocktake has influenced countries’ new climate commitments and international cooperation, drawing on these lessons to offer recommendations for the design and implementation of the GST2.
The event brings together organisations including Plataforma CIPÓ, the Brazilian Climate Center (CBC), the Center for Climate and Energy Solutions (C2ES), Climate of Politics, IDDRI and the Wuppertal Institute.
12 November | Using Experiences from Long-Term Strategies to Unlock Equitable and Credible Transitions Away from Fossil Fuels
Time: 16:15–17:15
Location: Regional Climate Foundations Pavilion, COP31, Antalya
Organised by IDDRI, this session will explore how experiences and lessons from long-term climate strategies can help countries develop credible, equitable and actionable pathways away from fossil fuels.
The discussion will focus on the role of long-term planning in supporting climate transitions and translating national climate commitments into effective action.
This topic is particularly relevant to ACCLIMATE's work on improving the coherence between NDCs and Long-Term Strategies (LTS), while considering the feasibility and fairness of national climate pathways.

13 November | Scaling the Energy Transition through NDC 3.0 Implementation and Long-Term Net-Zero Strategies
Time: 14:30–16:00
Location: French Pavilion, COP31, Antalya
On 13 November, Hélène van Rossum from IDDRI will present “From Commitment to Transformation: Scaling the Energy Transition” as part of a session examining how countries can accelerate the energy transition through the implementation of their NDC 3.0 commitments and long-term net-zero strategies.
The event will contribute to discussions on translating climate ambition into concrete policies and strengthening the connections between near-term commitments and long-term transformation.
These questions are central to ACCLIMATE's research, which seeks to identify effective mitigation pathways and policy options that support climate-resilient, low-emission development.

Connecting climate research with international policy
ACCLIMATE aims to support more coherent and effective national and international climate strategies through scientific research, modelling and stakeholder engagement. The project examines how countries can strengthen their NDCs and long-term strategies, taking into account adequacy, feasibility, fairness and the broader goals of sustainable development.
The second Global Stocktake is particularly relevant to this work. ACCLIMATE is developing research and policy insights intended to inform international climate processes, including GST2, and support countries in identifying pathways towards the goals of the Paris Agreement.
