This month, The Economics of Ecosystems and Biodiversity (TEEB), a "a global initiative focused on drawing attention to the economic benefits of biodiversity" released its report Natural Capital at Risk: The Top 100 Externalities of Business(2013). According to the executive summary, this 43-page report available here, discusses the following:
Natural capital assets fall into two
categories: those which are non-renewable and traded, such as fossil fuel and
mineral “commodities”; and those which provide finite renewable goods and
services for which no price typically exists, such as clean air, groundwater
and biodiversity. During the past decade commodity prices erased a century-long
decline in real terms, and risks are growing from over-exploitation of
increasingly scarce, unpriced natural capital. Depletion of ecosystem goods and
services, such as damages from climate change or land conversion, generates
economic, social and environmental externalities. Growing business demand for
natural capital, and falling supply due to environmental degradation and events
such as drought, are contributing to natural resource constraints, including
water scarcity. Government policies to address the challenge include
environmental regulations and market-based instruments which may internalize
natural capital costs and lower the profitability of polluting activities. In
the absence of regulation, these costs usually remain externalized unless an
event such as drought causes rapid internalization along supply-chains through
commodity price volatility (although the costs arising from a drought will not
necessarily be in proportion to the externality from any irrigation). Companies
in many sectors are exposed to natural capital risks through their supply
chains, especially where margins and pricing power are low. For example,
Trucost’s analysis found that the profits of apparel retailers were impacted by
up to 50% through cotton price volatility in recent years. Economy-wide,
these risks are sufficiently large that the World Economic Forum cites ‘water
supply crises’ and ‘failure of climate change adaptation’ along with several
other environmental impacts among the most material risks facing the global
economy.
This study monetizes the value of unpriced
natural capital consumed by primary production (agriculture, forestry,
fisheries, mining, oil and gas exploration, utilities) and some primary
processing (cement, steel, pulp and paper, petrochemicals) (see Appendix 3) in
the global economy through standard operating practices, excluding catastrophic
events. For each sector in each region (region-sector), it estimates the
natural capital cost broken down by six environmental key performance indicators
(EKPIs), and a ranking of the top 100 costs is developed from this. It also
estimates the 20 region-sectors with the highest combined impacts across all
EKPIs to provide a platform for companies to begin to assess exposure to unpriced natural
capital, both directly and through supply chains. In doing so it allows
investors to consider how their assets may be exposed. It also highlights
sector-level variation in regional exposure to impacts to identify
opportunities to enhance competitive advantage. It does not attempt to assess
the rate at which these costs may be internalized, and whether sectors are able
to adapt, but attempts to give a high-level view of where natural capital risk
lies, and what this could mean for business profitability in a more sustainable
regulatory environment.
