The National Nanotechnology Coordination Office (NNCO) announced on November 28, 2022, that the kickoff workshop for Nano4EARTH will be held January 24-25, 2023. Nano4EARTH will leverage recent investments in understanding and controlling matter at the nanoscale to develop technologies, industries, and training opportunities that address climate change. Nano4EARTH recognizes the role nanotechnology plays in: evaluating, monitoring, and detecting climate change status and trends; averting future greenhouse gas (GHG) emissions; removing existing GHGs; training and educating a highly skilled workforce to harness nanotechnology solutions; and developing higher resilience to, and mitigation of, climate change-induced pressures for improved societal/economic resilience. Members of the National Nanotechnology Initiative (NNI) community — the scientists, engineers, entrepreneurs, and government leaders developing solutions at the nanoscale — are invited to participate in Nano4EARTH. The kickoff workshop will serve as an information-gathering exercise to identify key feasible outputs of the challenge and effective ways to measure success.
