A leader in the controlled environment agriculture (“CEA”) space, where it uses 90% less water and 90% less land than traditional agriculture, Local Bounti is focused on significantly increasing produce shelf life, reducing waste and emissions, and addressing the availability of high-quality produce in local communities. Local Bounti’s sustainably-grown produce is cultivated locally, reducing food miles – the largest contributor to greenhouse gas emissions in the current produce supply chain. The environmental greenhouse conditions help to ensure nutritional value and taste, and Local Bounti’s products are non-GMO and pesticide/herbicide free. Local Bounti’s sustainable, root-on, living product results in less environmental impacts, carbon footprint, and less waste.
