ECEMF will bring together the community of European energy and climate modellers and policymakers, the data, scenarios and the tools to build the digital infrastructure needed, and apply them to an exciting research programme focussed on climate neutrality. These activities will generate the required coherent scientific evidence base and communicate the insights to accelerate progress towards policy goals, inform the implementation of measures at the national and European levels while removing barriers to participation, and championing transparency and openness.
