The concept of natural capital
梳理了自然资本作为资本资产的概念，探讨了弱可持续性与强可持续性的对立观点及其对绿色核算的影响，并指出自然资本概念对制定合理政策至关重要。
The natural environment is now commonly viewed as a form of capital asset, or natural capital. Also included are ecosystems that provide important goods and services to the economy. Managing natural capital has consequences for sustainable development. However, there are contrasting weak versus strong sustainability views, which in turn have implications for ‘green’ accounting. Natural resource-based sovereign wealth funds have emerged as key financial instruments for compensating resource depreciation with greater economy-wide investments. Recent scientific evidence recommends demarcating ‘safe operating spaces’ to limit exploitation of critical global biophysical subsystems or processes. These challenges suggest that the concept of natural capital is pivotal to sound policy.
