Our Mission and Vision

The Wright Foundation for Sustainability and Innovation exists to foster innovative sustainability initiatives that make a positive impact on our planet. We want to find solutions to the complex challenges facing our world today.

Our vision is to facilitate positive action toward sustainable and innovative solutions in agricultural and environmental sectors that reduce carbon footprints and minimize risk for our communities.

Grant Programs

Wright Foundation for Sustainability and Innovation administers projects directly funded by donors that help reduce carbon footprints through carbon positive practices and emission offsetting. The foundation holds open application periods for projects in the contiguous United States, Puerto Rico and Canada that focus on reducing environmental risk through regenerative agricultural practices, habitat restoration and using natural energy sources to make our communities more sustainable.

Reducing Carbon Footprints

The foundation supports projects that work to reduce carbon footprints through the following initiatives.

Habitat Reclamation

• Restoration of habitats creates spaces for native flora and fauna and microorganisms to survive. Natural landscapes are integral to functioning ecosystems and increasing biodiversity, not to mention creating habitats for pollinator species like bees and butterflies that we so desperately need for agricultural success.

Regenerative Agriculture

• Regenerative agricultural practices have a far-reaching impact on the industry and our lives. We aim to reduce carbon emissions by fostering projects that innovate row crop sustainability and dairy, beef, pork and poultry operations to create practices that are sustainable for years to come.

Renewable Energy

• We care about carbon positive practices that harness renewable resources like solar, wind and biomass for improved efficiencies and overall reduction in use. Organic matter often sourced from agricultural production, garbage and tree pruning can be converted to energy in various ways, recycling it back into the agricultural operation that created it or fueling our communities.

Soil

• Soil sequestering practices have wide-reaching benefits like restoring and building organic matter in the soil and increasing biodiversity. It boosts water infiltration and retention and reduces erosion. Through practices like no till, applying organic matter like manure and biochar, and planting cover crops, we improve soil health as well as take CO2 out of the atmosphere.

Tree Planting

• Planting trees is a simple act that makes a huge impact in our urban, suburban and rural communities. They provide shade, release oxygen and improve air quality, improve soil quality and biodiversity, all of which contributes to offsetting carbon emissions.  

• Water
• We want to find ways to protect and restore the integrity of our water resources. We aim to fund projects focused on practices that create efficiencies and reduce the agricultural production impact on water quality and benefit our communities by conserving one of our most important natural resources. 

John Harsch Regenerative Agriculture Grant
