Based on EKC hypothesis, this article analyzed the influencing mechanism between export and carbon emission in Henan Province. The result shows that export is an important factor that may cause carbon emission in Henan Province, however, with the improvement of export structure from low value-added orientation to high value-added orientation, the pressure of carbon emission reduction will be relieved. Hence, as far as export is concerned, to strive to develop the export of high value-added industry is the only way for changing the carbon emission path in Henan Province.
