Natural capital refers to natural resources and ecosystems that provide valuable goods and services to humanity. Investing in natural capital is important because ecosystems provide trillions of dollars in economic value but are being degraded. The overexploitation of natural resources has resulted in a biodiversity crisis that costs the global economy more than banking crises. To invest in natural capital, companies should assess their impacts on ecosystems, put a price on nature's value, optimize resource use, invest in conservation, and engage suppliers to bring solutions to scale. There are various ways to estimate the economic value of ecosystem services, including carbon taxes, direct market valuation using market prices or avoided costs, to incorporate nature's value into business decisions and manage risks.
