EUCalc replies to topic a) Managing technology transition. The EUCalc project will deliver a much needed comprehensive framework for research, business, and decision making which enables an appraisal of synergies and trade-offs of feasible decarbonisation pathways on the national scale of Europe and its member countries + Switzerland. The novel and pragmatic modelling approach is rooted between pure complex energy system and emissions models and integrated impact assessment tools, introduces an intermediate level of complexity and a multi-sector approach and is developed in a co-design process with scientific and societal actors. EUCalc explores decisions made in different sectors, like power generation, transport, industry, agriculture, energy usage and lifestyles in terms of climatological, societal, and economic consequences. For politicians at European and member state level, stakeholders and innovators EUCalc will therefore provide a Transition Pathways Explorer, which can be used as a much more concrete planning tool for the needed technological and societal challenges, associated inertia and lock-in effects. EUCalc will enable to address EU sustainability challenges in a pragmatic way without compromising on scientific rigour. It is meant to become a widely used democratic tool for policy and decision making. It will close - based on sound model components - a gap between actual climate-energy-system models and an increasing demands of decision makers for information at short notice. This will be supported by involving an extended number of decision-makers from policy and business as well as other stakeholders through expert consultations and the co-design of a Transition Pathways Explorer, a My Europe 2050 education tool and a Massive Open Online Course.

RethinkAction puts citizens and decision-makers at the core of the climate change action, by developing a cross-sectoral user-friendly decision-making platform tailored to the needs of different end-users for delivering clear and valuable information on climate change, increasing awareness and attractiveness of mitigation and adaptation solutions centred on land use as a key driver, even critical, to sustain life and to reach objectives in the context of climate change. RethinkAction moves beyond just informing them about the desirable future and what needs to be changed, but guiding them in the decision-making process by showing how to do it through practical land-use based solutions, while at the same time building awareness and attractiveness of new lifestyles and behavioural change, and how barriers can be overcome. By co-creating of the solutions through participatory processes, RethinkAction will unquestionably promote climate change action and acceptability of the measures. RethinkAction platform will allow users to assess land use-based adaptation and mitigation solutions, understand climate change impacts over time, linking local, EU and global scales based on 6 representative case studies, covering the main regional differences related to climate change.

The objective of LOCALISED is to downscale national decarbonization trajectories consistent with Europe's net-zero target to the local levels and provide the results to local authorities, citizens and businesses, in a way that would speed up the uptake of mitigation and adaptation actions. To this end, the project will create effective and clearly understandable tools that transform localised data on possible decarbonisation pathways by 2030 and 2050 into knowledge for action, namely: (1) the Decarbonisation Profiler for municipalities, regions and their citizens, providing information in all 24 EU languages, and (2) the Net-Zero Business Consultant tool. The tools will allow local authorities and policy-makers as well as citizens and businesses: to identify viable combinations and best practices of (sectoral) mitigation and adaptation measures for every NUTS3 region on how to reach the goals of the downscaled pathways and to introduce an adapted-to-case service for implementation and monitoring of SECAPs. This is closing a gap as the few currently available European platforms providing information on energy transition to net-zero in Europe have so far limited their scope and results to the national level (EUCalculator, INNOPATHS, CTI-2050), which is of little use at the level where the changes must be implemented. The project will additionally engage with EU citizen groups to inform how climate change and different EU net-zero scenarios positively and negatively affect their life and what share of mitigation can be enhanced via key behavioural change. Three local and five associated partners from local and regional administrations and business organisations will inform the development and test the tools. They will also be instrumental in supporting upscaling and replication through local and European dissemination and networking.

Climate change phenomena represent the most serious threats to human well-being and sustainable development. This affects several dimensions of human life from individual health issues to economic growth, passing through civil protection, with strong impacts on European territories and in several other world regions. The I-CHANGE (Individual Change of HAbits Needed for Green European transition) project faces the challenge of engaging and promoting the active participation of citizens for addressing climate change, sustainable development and environmental protection in the framework of the European Green Deal , the European Climate Pact and the European Biodiversity Strategy for 2030. The overall driving concept is that citizens and civil society have a central role in the definition of environmental protection and climate action and their direct involvement is essential to drive a true shift and promotion of changes of behaviors towards more sustainable patterns. I-CHANGE represents a change of paradigm achievable through a multi-disciplinary and participatory approach: improvement of data usability - citizen awareness raises through the observation of the environmental impacts of human activities; active participation of citizens - the active involvement of citizens through a set of Living Labs (LLs) located in different socio-economic contexts; climate change awareness - the development of clear understanding for citizens of the scientific processes underlying climate change and environmental protections.
