On 11 December 2025, within the Council of Engineers for the Energy Transition (CEET) Council Meeting, the SDSN Global Climate Hub team organised the Energy Data and System Modelling Workshop. The workshop presented scientific evidence demonstrating how integrated, cross-sectoral modelling can strengthen climate decision-making and accelerate progress towards climate neutrality and resilience.
Through presentations by Professor Dr. Phoebe Koundouri, Chair of the SDSN Global Climate Hub, and Dr. Ioannis Arampatzidis, Senior Researcher at the SDSN Global Climate Hub, the Hub’s integrated systems-nexus approach was showcased. This approach links energy and emissions with food–land dynamics, biofuels potential, land requirements for renewable energy, and water constraints. The presentations emphasised that science-based solutions must be complemented by meaningful stakeholder engagement—through co-design, living labs, and participatory processes—to ensure the development of implementable and effective transition pathways.
In this context, results from the assessment of the National Energy and Climate Plans (NECPs) of 35 European countries were presented. The analysis demonstrated that full implementation of national plans can deliver substantial emissions reductions, while also highlighting the need to better address cross-sectoral trade-offs, including land and water constraints, and to strengthen implementation mechanisms.
The workshop further discussed the SDSN Global Climate Hub’s updated modelling framework, which is applicable at the global scale, and explored potential avenues for future collaboration with the CEET.
About the Council of Engineers for the Energy Transition (CEET)
Established under the auspices of the United Nations Secretary-General, the Council of Engineers for the Energy Transition is a high-level, independent body of engineers and energy systems experts advising the United Nations on pathways to achieve net-zero emissions by 2050. Launched in 2021, the CEET is co-chaired by Gerd Müller, Director General of UNIDO, and Professor Jeffrey Sachs, President of the Sustainable Development Solutions Network (SDSN).
About the SDSN Global Climate Hub
The SDSN Global Climate Hub (GCH) is a global science–policy initiative of the United Nations Sustainable Development Solutions Network. It develops national and international integrated systems solution pathways towards climate neutrality and climate resilience, embedded in socio-economic and financial systems and supported by stakeholder co-design and participatory processes. Established in 2022, the SDSN Global Climate Hub is led by Professor Phoebe Koundouri.
