Global: World's top firms cause $2.2tn of environmental damage, report estimates

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if they were held financially accountable, a major unpublished study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.

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.

Later this year, another huge UN study - dubbed the "Stern for nature" after the influential report on the economics of climate change by Sir Nicholas Stern - will attempt to put a price on such global environmental damage, and suggest ways to prevent it. The report, led by economist Pavan Sukhdev, is likely to argue for abolition of billions of dollars of subsidies to harmful industries like agriculture, energy and transport, tougher regulations and more taxes on companies that cause the damage.

of changes which would have a profound effect - not just on companies'
profits but also their customers and pension funds and other investors
- the UN-backed Principles for Responsible Investment
initiative and the United Nations Environment Programme jointly ordered
a report into the activities of the 3,000 biggest public companies in
the world, which includes household names from the UK's FTSE 100 and
other major stockmarkets.

The study, conducted by London-based consultancy Trucost
and due to be published this summer, found the estimated combined
damage was worth US$2.2 trillion (£1.4tn) in 2008 - a figure bigger
than the national economies of all but seven countries in the world
that year.

The figure equates to 6-7% of the companies' combined
turnover, or an average of one-third of their profits, though some
businesses would be much harder hit than others.

"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.

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.

did not want to comment before the final report on which sectors
incurred the highest "costs" of environmental damage, but they are
likely to include power companies and heavy energy users like aluminium
producers because of the greenhouse gases that result from burning
fossil fuels. Heavy water users like food, drink and clothing companies are also likely to feature high up on the list.

said the heads of the major companies at this year's annual economic
summit in Davos, Switzerland, were increasingly concerned about the
impact on their business if they were stopped or forced to pay for the

"It can make the difference between profit and loss," Sukhdev told the annual Earthwatch Oxford lecture last week.
"That sense of foreboding is there with many, many [chief executives],
and that potential is a good thing because it leads to solutions."

aim of the study is to encourage and help investors lobby companies to
reduce their environmental impact before concerned governments act to
restrict them through taxes or regulations, said Mattison.

going to be a significant proportion of a lot of companies' profit
margins," Mattison told the Guardian. "Whether they actually have to
pay for these costs will be determined by the appetite for policy
makers to enforce the 'polluter pays' principle. We should be seeking
ways to fix the system, rather than waiting for the economy to adapt.
Continued inefficient use of natural resources will cause significant
impacts on [national economies] overall, and a massive problem for
governments to fix."

Another major concern is the risk that
companies simply run out of resources they need to operate, said Andrea
Moffat, of the US-based investor lobby group Ceres,
whose members include more than 80 funds with assets worth more than
US$8tn. An example was the estimated loss of 20,000 jobs and $1bn last
year for agricultural companies because of water shortages in
California, said Moffat.
