Trucost has undertaken this study on behalf of the TEEB for Business Coalition. Findings of this report build on TEEB’s The Economics of Ecosystems and Biodiversity in Business and Enterprise and the World Business Council for Sustainable Development’s Guide to Corporate Ecosystem Valuation by estimating in monetary terms the financial risk from unpriced natural capital inputs to production, across business sectors at a regional level. By using an environmentally extended input-output model (EEIO), it also estimates, at a high level, how these may flow through global supply chains to producers of consumer goods. It demonstrates that some business activities do not generate sufficient profit to cover their natural resource use and pollution costs. However, businesses and investors can take account of natural capital costs in decision making to manage risk and gain competitive advantage.

 

Highlights

  • The primary production and primary processing sectors analyzed in this study are estimated to have unpriced natural capital costs totalling US$7.3 trillion, which equates to 13% of global economic output in 2009.
  • The majority of unpriced natural capital costs are from greenhouse gas emissions (38%) followed by water use (25%); land use (24%); air pollution (7%), land and water pollution (5%) and waste (1%). 
  • No high impact region-sectors generate sufficient profit to cover their environmental impacts. Subject to adaptive capabilities, this will cause them to pass on these costs to customers. Region-sectors most at risk include coal power generation in Eastern Asia and Northern America, wheat farming in Southern Asia, and cattle ranching in South America and Southern Asia.
  • Companies and investors can use information on the region-sectors that have the largest natural capital costs to assess the possible scale of direct, supply-chain and investment risks. Regional and sectoral variations present opportunities for businesses to enhance competitive advantage, and for investors to improve relative returns.

Extract


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.

Why did TEEB commission the report?


When looking at natural capital risk in financial terms the world’s 100 biggest risks are costing the economy around $4.7 trillion per year in terms of the environmental and social costs of lost ecosystem services and pollution.

Many of these natural capital costs are found in the developing world, but the resulting goods and services are being consumed by resource intensive supply chains around the planet – thus it is a global challenge for a globalized world.

Although internalization of natural capital costs has only occurred at the margin, 3 billion new middle class consumers by 2030 will cause demand to continue to grow rapidly, while supply will continue to shrink. The consequences in the form of health impacts and water scarcity will create tipping points for action by governments and societies. The cost to companies and investors will be significant.

This research provides a high-level insight into how companies and their investors can measure and manage natural capital impacts. While it has limitations, it should act as a catalyst for further research into high risk areas, and mitigation action. For governments it should spark further debate around the risks their countries face, and whether natural capital is being consumed in an economically efficient manner. The scale of the risks identified suggests that all actors have the opportunity to benefit.
