Environmental groups want a substantial reduction in the emission of greenhouse gases. 環保組織要求切實減少溫室氣體的排放量。
There is an interesting look at emissions trading, which is going to take an increasing role and for which biological sinks may be significant.
Above it is assumed that quotas are allocated according to emissions.
The marginal costs of carbon dioxide emissions and the returns to investment in development are readily compared.
We estimate the marginal cost of reducing carbon emissions beyond the existing baseline.
We may also say that the adjustment of emissions is effected within almost three periods.
Option values are attached to the three possibilities: to stop emissions temporarily, to exit entirely and to re-start polluting (for an 'entry fee').
However, emissions are not necessarily the most relevant measure of (subjective) environmental quality.
Note that particulate emissions from the chemical plant are significantly higher than emissions from the iron foundry.
