Task 5. Set the trajectory towards climate objectives for operational carbon  Task 6. Managing the stakeholder groups and organising a final workshop for  stakeholders at large  As the roadmap will set out milestones for whole life carbon, both embodied and operational  carbon shall be included. While most of this study is focusing on embodied carbon, data for  operational carbon, largely existing, must be collected and processed so that it can be  combined with embodied carbon in the roadmap for whole life carbon. This concerns scope,  building types, functional units etc. This task shall as much as possible be based on the sectoral breakdown for the building sector  of EU climate policies for 2030 and 2050, the national energy and climate plans (NECPs) and  the Long Term Renovation Strategies provided by Member States, with their identified  milestones up to 2050. Other national and industry sector roadmaps will also inform this task.  Links between operational and embodied carbon shall be considered.  The result of this task shall give a reliable overview of Member States trajectories for  operational carbon, and be presented in a way that it can be combined with the trajectories for  embodied carbon, as much as possible along the same factors and milestones as set out above,  in particular using the same regions.  The stakeholder groups set up in task 1 should be used to ensure a collaborative process  throughout the tasks, to serve the purpose of quality and buy in on the results of this study.  The contractor shall organise meetings, workshops, bilaterals etc, online or onsite, as the  situation allows and as serves best the purpose, with the stakeholder groups. The groups shall  be informed early on about the process, schedule, what is expected of them when and should  always be suitably informed to be able to contribute in the best way possible.  At the end of the study, a workshop presenting its results to relevant stakeholders shall be  organised by the contractor. In the case of an onsite workshop, this should take the form of a  one-day event at the Commission’s premises in Brussels. The contractor will be responsible  for the invitation to and promotion of the workshop to all relevant stakeholders.  This task will have to be flexible enough to account for potential organizational constraints.  As today, there are uncertainties about the possibility to hold large public events even within a  one-year timeframe due to the current COVID-19 crisis. If the situation allows, the  Commission expects that around 200 people may attend a meeting in Brussels. The event  would then take place at the Commission’s premises and/or the Commission would take care  of the venue of the event. No travel costs would be reimbursed for participants. Travel and  subsistence costs for the contractor should be included in the contract value.  If the situation does not allow for large physical meetings, an alternative is to organize an  online event. Most recent experience has shown that events organized online have the  potential to gather a greater number of attendant than traditional physical events. The  contractor will have to provide IT solutions able to cope with at least 1000 simultaneous  connexions in case of an online event.  If the physical event does not take place, the Commission can discuss with the contractor if  there is a need to allocate some of the resources foreseen within this task to any other task  under this contract.  9
