The Environmental Protection Agency (EPA) plays a vital role in fostering sustainability and environmental innovation by offering grants to support green businesses. Under the American Recovery and Reinvestment Act (ARRA) of 2009, the EPA allocates funding to initiatives that promote sustainability and environmental protection nationwide. In addition to ARRA grants, various other green grant programs are available to help entrepreneurs and organizations develop innovative, eco-friendly projects, advancing environmental stewardship and green business practices across the United States.
