Natural capital is another term for the stock of renewable and non-renewable natural resources (e.g. plants, animals, air, water, soils, minerals) that combine to yield a flow of benefits to people. With financial capital, when we spend too much we run up debt, which can, if unchecked, eventually result in bankruptcy. With natural capital, if we keep drawing down stocks without allowing or encouraging nature to recover, we run the risk of local, regional or even global ecosystem collapse. There are a growing number of businesses from all around the world that are valuing natural capital. The Natural Capital Coalition is developing a Protocol Application Program to support businesses as they begin to measure, value and integrate natural capital considerations into their business decisions. IdeaSpies is very pleased to be a natural capital coalition organisation. www.naturalcapitalcoalition.org
