The Challenge organisers realise human induced climate change is the most pressing concern of our time. Yet it is a complex issue with many interdependencies and uncertainty, necessitating broad participation in potential solutions. However, developments in knowledge, technology and modes of communication enable new opportunities to understand and address its causes and consequences. Data, modelling and visualisation are key to such developments and play a significant role in measuring emissions, calculating offsets, locating adaptive interventions, etc. Some of this data is available openly, for example as open data published on the Dublin region and National open data portals.

The organisers are looking for solutions which use available data for analyses, applications, tools, maps, etc. to drive or support climate action in some shape or form. All data-based proposals with the potential to contribute to climate action are welcome. These may align with the Climate Change Action Plans 2019-2024 five themes:

• Energy & buildings: e.g., how can existing data and analysis for energy and buildings be used to increase engagement of citizens and businesses in climate action? What are the opportunities for visual representation of renewable energy consumption/microgeneration/energy efficiency potential of buildings? How could the energy transition transform the lives of citizens?

• Flood Resilience: e.g., how will increased rainfall, extreme weather events, sea level rise and coastal erosion affect the Dublin region? How will changing coastlines impact on coastal communities? How can data and its applications increase awareness of various forms of flooding, and inform interventions such as Sustainable Urban Drainage Systems, Green Infrastructure and other climate resilient solutions?

• Nature Based Solutions & Biodiversity: nature provides valuable ecosystem services such as clean air and water, food and medicine, recreation, and climate regulating services (i.e., temperature). How can we use data to protect, improve and increase access to nature and realise the multiple benefits of NBS and biodiversity while increasing resilience to climate change?

• Transport: e.g., how can data be used to help drive the uptake of active travel, public transport or other shared mobility (e.g.) car sharing? How can data/solutions inform the locations for remote working hubs and increase the awareness and usage of remote working hubs? How can data inform/influence targets around the switchover to Electric Vehicles?

• Resource management and circular economy: we must transition from our existing take-make-waste system to a circular economy. How can data help monitor this transition (e.g.) improve recycling levels or reduce waste by households and businesses? How can data help encourage sectors to become more circular? Can we demonstrate how moving to a circular economy will impact on climate change?
