By connecting local solutions to global systems, we support coordinated, place-based action through a suite of tools, a robust grantmaking strategy, and storytelling platforms that inform, guide, and inspire change. Our core insight is that solving the climate crisis requires shifting both culture and capital. Narratives shape priorities, and priorities shape where resources flow. To scale the solutions our planet needs, we must change both the story people tell about climate action and the systems that determine where investment goes. To do this, One Earth has built a set of interconnected tools that answer three foundational questions: what to invest in, where it matters most, and how capital needs to shift to support them. WHAT TO INVEST IN: The One Earth Solutions Framework identifies more than 75 science-based pathways across Energy Transition, Nature Conservation and Regenerative Agriculture that are required to stabilize the climate and protect biodiversity. WHERE IT MATTERS MOST: The Global Safety Net and Bioregions Framework identify priority places landscapes and seascapes where conservation and restoration efforts can deliver the greatest ecological impact. HOW CAPITAL MUST SHIFT: Through the Minding the Gaps report and the Solutions Finance Tracker, One Earth analyzes how climate finance is currently allocated across solutions and highlights where critical funding gaps remain. Together, these tools translate complex science into clear priorities for philanthropy, investment, and policy, and inform the One Earth Fund, which mobilizes catalytic philanthropic capital toward the most underfunded, high-impact solutions and geographies identified through our research and network. At the same time, One Earth's storytelling platforms, including the Solutions Hub and global media partnerships, help bring these solutions and the people leading them to life. By making climate solutions tangible, relatable, and inspiring, we help shift cultural understanding toward a vibrant future that is possible. By connecting science, story, and capital, One Earth helps align the climate movement around the solutions that can deliver on the ground impact and systems-level change. 0 0 0 5318227 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 0 0 1 1 1 1 0 0 0 0 1 0 1 0 0 0 0 0 0 1 0 1 0 0 0 0 0 0 0 0 1 14 0 11 1 0 0 0 0 0 0 0 0 0 0 0 0 X 10 9 0 0 0 0 0 0 0 1 1 0 0 1 1 1 1 1 1 1 0 0 AK AR CA FL GA HI IL KS KY MA MD MI MN MS NC ND NH NJ NM NY OK OR PA RI SC TN UT VA WI WV X X X 100 Degrees Consulting 6786324534 PO Box 222 Clarence Center NY 14032 Justin Winters President, Co-Founder, ED, and Board Member 40 0 X X 262479 0 13646 Karl Burkart Co-founder & Deputy Director 40 0 X 184417 0 11882 Kate Thomas Director of Philanthropy and Partnerships 40 0 X 109273 0 6746 Jesse Ladner Director of Operations 40 0 X 105275 0 7661 Edward Bell Digital Media Director 40 0 X 103396 0 7454 Jay Halfon Board Member 1 0 X 0 0 0 Rachel Rivera Board Member 1 0 X 0 0 0 Rick Ridgeway Board Member 1 0 X 0 0 0 Sarah Woodhead Board Member 1 0 X 0 0 0 Tenzin Seldon Board Member 1 0 X 0 0 0 Brad Leibov Board Chair 1 0 X X 0 0 0 Coretta Anderson Treasurer 1 0 X X 0 0 0 Jena King Secretary 1 0 X X 0 0 0 Will Peterffy Board Member 1 0 X 0 0 0 764840 0 47389 5 0 1 0 Kin Creative LLC 563A Quincy Street Brooklyn NY 11221 Web Development 146650 1 0 0 0 0 0 9581434 525172 9581434 Website Rebuild and Support 541512 26099 26099 0 0 0 0 0 0 26099 25703 0 0 25703 0 0 0 0 0 0 0 0 0 0 504562 0 522743 0 -18181 0 -18181 0 0 -18181 0 0 9615055 26099 0 7522 2955440 2955440 0 0 1046766 1046766 0 0 276125 179481 27613 69031 0 0 0 0 845099 537268 167142 140689 49111 30778 9915 8418 131132 82932 32228 15972 87503 55878 15659 15966 0 0 0 0 10840 0 10840 0 77330 0 77330 0 217734 203593 11166 2975 4791 4791 26299 20044 4622 1633 111610 79423 23123 9064 19475 2478 16241 756 62471 53548 1108 7815 8529 5578 181 2770 63479 60229 3250 6309 6309 6000043 5318227 406727 275089 1594136 2165220 5063 2514679 1102320 57300 0 0 0 0 0 0 0 0 0 0 15165 29026 0 1401645 0 0 0 0 50979 323938 0 0 2767663 6491808 113639 106796 0 117488 0 0 0 0 0 0 0 0 0 0 0 0 113639 224284 X 300101 5779488 2353923 488036 2654024 6267524 2767663 6491808 3615012 -1512 0 0 0 0 X 0 1 X 1 0 X 5319840 5340643 5053126 4953747 9581434 30248790 5319840 5340643 5053126 4953747 9581434 30248790 6363759 23885031 0 0 51 126 25703 25880 0 0 0 0 0 4437 21 0 4458 30279128 93849 0.78883 0.71 X Schedule A, Part II, Line 10 Misc Income RESTRICTED RESTRICTED RESTRICTED RESTRICTED RESTRICTED RESTRICTED RESTRICTED RESTRICTED 0 0 X 9613543 -1512 0 0 0 -1512 9615055 0 0 0 9615055 6000043 0 0 0 0 0 6000043 0 0 0 6000043 Schedule D, Part X, Line 2 The organization has determined that there are no material uncertain tax positions that require recognition or disclosure in the financial statements. 1 Central America and the Caribbean 0 0 Grantmaking 3300 East Asia and the Pacific 0 0 Grantmaking 1100 Europe (including Iceland and Greenland) 0 0 Grantmaking 10000 Middle East and North Africa 0 0 Grantmaking 1100 North America (including Canada and Mexico, but not the United States) 0 0 Grantmaking 1024535 South America 0 0 Grantmaking 2200 South Asia 0 0 Grantmaking 1100 Sub-Saharan Africa 0 0 Grantmaking 3431 0 0 1046766 North America (including Canada and Mexico, but not the United States) SeaLegacy projects 617934 Wire 0 Europe (including Iceland and Greenland) Completion of a paper titled A Prioritization Strategy for Safeguarding Conservation Imperatives Sites 10000 Wire 0 2 0 Reporting on indigenous frontline environmental defenders in Mexico North America (including Canada and Mexico, but not the United States) 1 401406 Wire 0 0 0 0 0 0 0 Schedule F, Part I, Line 2 Proper use of grant funds is monitored by maintaining a close, continuous working relationship with the grantees as well as by reviewing reports (when appropriate) and witnessing the work of the projects and programs the grant funds supported. 1 The Nature Conservancy 4245 North Fairfax Drive Suite 100 Arlington VA 222031606 530242652 501(c)(3) 50000 0 GSN3: Mapping the least modified 50% of terrestrial surface (Least Modified Lands layer) Vibrant Data Labs 2152 1/2 Stuart Street Berkeley CA 94705 462550705 2891250 0 Climate Finance Tracker and Climate Solutions Opportunity Roadmap: To develop an interactive, visually searchable map of the corporate accountability ecosystem (focused on nature), including global and local NGOs NEO Philanthropy 1001 Avenue of the Americas 12th Floor New York NY 10018 133191113 501(c)(3) 5390 0 Daughters for Earth projects 2 1 Schedule I, Part I, Line 2 Proper use of grant funds is monitored by maintaining a close, continuous working relationship with the grantees as well as by reviewing reports (when appropriate) and witnessing the work of the projects and programs the grant funds supported.

Form 990, Part VI, Section B, Line 12c Each director, principal officer, and member of a committee with board-delegated powers annually signs a Conflict of Interest disclosure statement; in addition, these individuals have an on-going duty to disclose any potential or actual conflicts of interest. Should a potential conflict be identified, the conflicted individual has the opportunity to disclose to the board all material facts; thereafter, the conflicted individual leaves the board meeting while the determination of conflict of interest is discussed and voted upon. Should the board determine an actual conflict of interest exists, the board exercises due diligence to determine whether the organization can obtain (with reasonable efforts) a more advantageous transactions or arrangement form a person or entity that would not give rise to a conflict of interest. If a more advantageous transaction or arrangement is not reasonably possible under circumstances not producing a conflict of interest, the board shall determine by a majority vote of the directors then in office (without counting the vote of the interested director or directors), whether the transaction is in the organization's best interest, for its own benefit, and whether it is fair and reasonable. The proceedings are recorded in the minutes of the board meeting. Form 990, Part VI, Section B, Line 15 Compensation for the executive director is established by independent voting members of the board of directors (as the executive director is also voting member of the board), who utilizes comparability data (including compensation surveys/studies and form 990s of other organizations) for similarly situated employees in similar organizations and geographic regions to substantiate its decision. This process is recorded in the board meeting minutes. Form 990, Part VI, Section C, Line 19 The organization makes its governing documents, conflict of interest policy, and financial statements available upon request.
