Government investment in natural capital

This paper presents a new approach to the measurement of natural capital. A distinguishing feature of this approach is the use of investment criteria that are consistent with the main features of physical capital, thus maintaining consistency in the measurement of different types of capital. This new approach was applied to the expenditures of the federal government in Canada as recorded in the Public Accounts for fiscal year 2004-05. My results indicate that, in 2004-05, total investment in natural capital by the federal government amounted to 2.6% of net budgetary expenditures. Spending on physical capital, the only component that is currently included as investment in the National Accounts, represented only 5% of total investment in natural capital.
