Summary

• Add Climate Action Navigator to the Users list
• Interactive dashboard to aid urban climate action. It translates high-resolution geospatial data into clear, neighborhood-level insights, giving cities, NGOs, and local initiatives the information they need to act. From identifying streets where walking infrastructure needs improvement to mapping areas with the highest heating emissions, CAN shows where targeted action will have the greatest impact.
