ESM2025 – Earth System Models for the Future

Over the past decades, climate science has demonstrated that human activities are responsible for global warming and a range of associated environmental impacts. The current generation of Earth System Models has been a centrepiece of these achievements, providing an important scientific basis for understanding climate change and informing policy action, both for mitigation

Over the past decades, climate science has demonstrated that human activities are responsible for global warming and a range of associated environmental impacts. The current generation of Earth System Models has been a centrepiece of these achievements, providing an important scientific basis for understanding climate change and informing policy action, both for mitigation and adaptation
to global change.

However, ESMs still need further development to reach their full potential in order to thoroughly design and assess the options needed to meet the objectives of the Paris Agreement. The project aims to develop a next generation of European ‘mitigation-oriented’ ESMs that can meet these objectives.

By developing a novel generation of ESMs, the project takes a step forward in providing relevant climate simulations for the design of comprehensive climate change mitigation and adaptation strategies, in line with the Paris Agreement. This next generation of ESMs will include an improved representation of the full Earth-system response to anthropogenic emissions, with a particular focus on human land-use change.

POLIZERO project final report

POLIZERO was funded by the Energy-Economy-Society research programme of the Swiss Federal Office of Energy. Led by the Energy Economics Group of the Laboraotry for Energy Systems Analysis at the Paul Scherrer Institute PSI and the Technoeconomics of energy systems laboratory of the University of Piraeus Research Center, it combined stakeholder input, energy modelling

Multiple pathways towards sustainable development goals and climate targets

The study presents three different sustainable development pathways, all of which avoid dangerous climate change and enable substantial progress towards the UN Sustainable Development Goals (SDGs). The scenarios were quantified by four different modelling teams participating in the SHAPE project, comprising two “full-system” integrated assessment models (REMIND-MAgPIE and IMAGE) and
