The Robert F. Orr Charitable Foundation is currently accepting applications for grants dedicated to charitable, educational, and scientific purposes. While the foundation's broad mission encompasses these areas, specific grantmaking priorities guide its funding decisions. The foundation seeks to align its support with initiatives that demonstrate a clear commitment to positive societal impact, particularly within the states of Hawaii, Idaho, and Utah. The foundation's grantmaking priorities are divided into three core areas: Environment, Education, and Human Services. Within the Environment category, the foundation prioritizes causes and programs that foster environmental conservation and support restoration projects, aiming to preserve and improve natural ecosystems. For Education, the focus is on K-12 STEM programs and job training initiatives, with the goal of enhancing educational opportunities and workforce development. In Human Services, the foundation supports programs for disadvantaged persons and individuals with disabilities, striving to improve their quality of life and promote inclusivity. Target beneficiaries for these grants include environmental organizations working on conservation and restoration, educational institutions and programs serving K-12 students in STEM fields, and organizations providing job training or services to disadvantaged and disabled individuals. The overarching impact goals are to contribute to a healthier environment, a more educated and skilled workforce, and a more equitable society for vulnerable populations within the specified states. While the document does not explicitly detail "expected outcomes and measurable results" or the foundation's "strategic priorities and theory of change," the articulated priorities strongly suggest a belief in the power of targeted support to create tangible, positive change in these key areas. Organizations seeking funding must qualify as exempt under Section 501(c)(3) of the Internal Revenue Code. Applications are accepted through an online grant application form or an accessible alternative for assistive technology users. The deadline for applications is July 1, 2024. While the size of the grant and its duration are not specified, the foundation's commitment to these defined priorities indicates a strategic approach to philanthropy, aiming for meaningful, albeit not precisely quantified, outcomes through its funding.

The County of Maui's Green Grants program offers approximately $1.7 million in funding to support projects promoting sustainability. Managed by the Department of Environmental Management’s Environmental Protection & Sustainability Division (EP&S), the program aims to advance critical initiatives in environmental protection, restoration, and sustainable development across Maui County. This aligns with the broader mission of fostering a more resilient and environmentally conscious community. The grants target a wide range of beneficiaries, including individuals, non-profit organizations, and for-profit businesses. The program particularly encourages projects led by, or with a focus on, women, youth, and traditional native Hawaiian practices and approaches. The overall impact goal is to enhance environmental protection, restore wetlands, promote renewable energy, encourage green building, and facilitate the acquisition of essential equipment for sustainability initiatives, ultimately contributing to a more sustainable Maui County. The Green Grants program prioritizes several key areas through its distinct funding streams. These include the Environmental Protection Grant, which supports invasive species management, environmental restoration, conservation, and sustainability (with a specific allocation for Waikapū community beautification). The Wetlands Restoration Grant focuses on organizations dedicated to wetland restoration. The Renewable Energy Grant supports initiatives promoting renewable energy and energy efficiency. The Green Building and Resilient Housing Grant encourages sustainable building practices, with a portion designated for Living Building Challenge participants. Finally, the Equipment Purchase Grant assists in acquiring necessary equipment for all sustainability and environmental initiatives. Expected outcomes include tangible improvements in environmental health, increased adoption of renewable energy, more sustainable building practices, and enhanced capacity for environmental initiatives through equipment acquisition. For instance, the Wetlands Restoration Grant aims to advance critical restoration efforts, while the Renewable Energy Grant seeks to enhance energy efficiency. The Green Building and Resilient Housing Grant promotes sustainable design and construction. Measurable results would include the number of restored wetlands, reduction in invasive species, new renewable energy installations, and the implementation of green building projects. The project period for grants is a full year, with options to align with either the Fiscal Year (July 1, 2024–June 30, 2025) or Calendar Year (January 1, 2025–December 31, 2025) in 2025.
