The cost of pollution and other damage to the natural environment caused by the world's biggest companies would wipe out more than one-third of their profits if they were held financially accountable, a major unpublished study for the United Nations has found.
The report comes amid growing concern that no one is made to pay for most of the use, loss and damage of the environment, which is reaching crisis proportions in the form of pollution and the rapid loss of freshwater, fisheries and fertile soils.
"What we're talking about is a completely new paradigm," said Richard Mattison, Trucost's chief operating officer and leader of the report team. "Externalities of this scale and nature pose a major risk to the global economy and markets are not fully aware of these risks, nor do they know how to deal with them."
The biggest single impact on the $2.2tn estimate, accounting for more than half of the total, was emissions of greenhouse gases blamed for climate change. Other major "costs" were local air pollution such as particulates, and the damage caused by the over-use and pollution of freshwater.
The true figure is likely to be even higher because the $2.2tn does not include damage caused by household and government consumption of goods and services, such as energy used to power appliances or waste; the "social impacts" such as the migration of people driven out of affected areas, or the long-term effects of any damage other than that from climate change. The final report will also include a higher total estimate which includes those long-term effects of problems such as toxic waste.
