Recording environmental assets in the national accounts

Accounting information is a core element of economic decision-making at both national and corporate levels. It is widely accepted that much economic activity is dependent upon natural capital and natural resources—generically termed environmental assets in an accounting context. Environmental assets are under threat of depletion and degradation from economic activity. Consequently, the incor- poration of information on environmental assets into standard accounting frameworks is an essential element in mainstreaming environmental information and broadening the evidence base for economic decisions and the assessment of sustainability. This paper describes the treatment of environmen- tal assets within the national economic accounts and summarizes recent developments that extend the accounting approaches as described in the United Nations’ System of Environmental-Economic Accounting (SEEA). The potential for implementation of accounting standards for environmental assets is shown through a description of work in Australia on environmental-economic accounting.

Wealth and sustainability

For economists in 1974, it was a live question whether the exhaustion of natural resources, such as oil, would necessarily lead to the decline of economic activity. Solow showed that constant levels of consumption could be sustained in the face of exhaustibility if there is sufficient substitutability between produced and natural factors of production. Hartwick then proved that underpinning this result is a saving rule—set investment in produced capital equal to the value of resource depletion at each point in time. A large literature has shown that a comprehensive measure of the change in real wealth—net saving—plays a central role in determining whether current well-being can be sustained. In particular, current declines in real wealth signal that future well-being will also decline, a result that has been confirmed empirically using data for developing countries. Changes in wealth and sustain- ability are therefore joined at the hip. The current composition of wealth serves to define the policy challenges that countries face in achieving sustainable development. If substitution possibilities are limited between natural and other factors of production, as one might expect, then technical progress is a necessary complement to policies for sustainability.
