Although the Czech Republic is on track to decarbonise, the concrete pathways need further examination and public discussion, in order to finish preparation of Czech Climate Mitigation Policy, and most importantly to ensure successful implementation of the 2050 low-carbon roadmap and deep decarbonisation. The workshop of the FP7 project CECILIA2050 contributed to this discussion with presentations on climate change policy options and modelling approaches to explore the impacts of decarbonisation pathways. For more information on the event is available at the website of the Environment Center of the Charles University in Prague.
