回答如下:

你指的應該是美國 EPA的AP 42的係數列表，目前最新的是第五版；但是它是一個很龐大的查表資料，涵蓋許多污染物，不知道你要的是哪一方面??

它的排放通式為

The general equation for emissions estimation is:

E = A x EF x (1-ER/100)

where: E = emissions; A = activity rate; EF = emission factor, and ER =overall emission reduction efficiency, %

你要的排放係數EF可以根據你的狀況下去查表。它的主要內容分為15章
