Dear Colleagues:

The National Science Foundation's (NSF) Directorates for Geosciences (GEO), Social, Behavioral and Economic Sciences (SBE), and Office of International Science and Engineering (OISE) jointly support research to address the twenty-first century global challenge of climate change by seeking to increase understanding of Carbon Dioxide (CO2) Removal (CDR) and Solar Radiation Modification (SRM) science, governance, and consequences. While the rapid reduction of CO2 and other greenhouse gas (GHG) emissions remains a top priority, the scientific community has urged federal agencies to support research on additional potential solutions and their consequences, including strategies that may ameliorate anthropogenic climate change ^1-3. In addition, recent U.S. Government reports ^4-5 seek to mobilize the Federal Government and civil society toward enhancing current understanding of potentially effective and innovative climate mitigation strategies. This Dear Colleague Letter (DCL) seeks to encourage submission of proposals on the fundamental understanding and assessment of environmental processes, and/or social, cultural, and ethical impacts of CDR and SRM.

CDR and SRM encompass a broad and growing range of strategies, each with specific potential environmental, and societal impacts and unintended consequences ^1-3. Effective strategies need to be co-developed in an environmentally and socially responsible manner that includes community-engaged research promoting and adhering to open scientific research aligned with FAIR ⁶ and CARE ⁷ principles of data sharing and data use. This DCL welcomes proposals in relevant areas of research that align with participating divisions, with particular interest on projects that integrate research programs from both GEO and SBE. Examples include projects that have integrative engagement with ethical frameworks, governance structures, and/or environmental justice issues that help guide research and potential scaling and deployment of CDR and SRM measures. Requests to form and foster interdisciplinary national and international research teams are particularly encouraged through submission of types of proposals described in Chapter II.F of the NSF Proposal & Award Policies & Procedures Guide (PAPPG), including planning, workshop ⁸, Grant Opportunities for Academic Liaison with Industry (GOALI), and Research Advanced by Interdisciplinary Science and Engineering (RAISE), and to existing program solicitations including Research Coordination Network (RCN), AccelNet, and Global Centers.

This DCL does not constitute a new competition or program. Rather, interested proposers should prepare and submit proposals in accordance with the guidance contained in the PAPPG and any solicitation or program specific instructions for the relevant programs.

All relevant programs within participating Divisions/Offices:
GEO/Division of Atmospheric and Geospace Sciences
GEO/Division of Earth Sciences
GEO/Division of Ocean Sciences
GEO/Office of Polar Programs
SBE/Division of Behavioral and Cognitive Sciences
SBE/Division of Social and Economic Sciences
OISE

Alexandra R. Isern
Assistant Director for Geosciences (GEO)
