This paper tests for the applicability of the Environmental Kuznets Curve (EKC) hypothesis at the Canadian and provincial/territorial levels using greenhouse gas emissions as an indicator for environmental degradation. The hypothesis is tested using provincial and territorial panel data from 1990 to 2014. The results vary depending on the econometric estimation method. The pooled regression results are mixed, with the EKC hypothesis confirmed at the Canadian level and in half of the provinces and territories. However, the fixed-effects regression results confirm the EKC hypothesis at the Canadian level and in all provinces and territories. The results also highlight the significance of technological change and province/territory specific characteristics in determining the level of greenhouse gas emissions.

本文使用温室气体排放作为环境退化的指标，测试了环境库兹涅茨曲线（EKC）假设在加拿大和省/地区的适用性。使用1990年至2014年的省级和地区性面板数据对假设进行了检验。结果根据计量经济学的估算方法而有所不同。合并的回归结果好坏参半，在加拿大和一半的省和地区中，EKC假设得到了证实。但是，固定效应回归结果在加拿大以及所有省和地区都证实了EKC假设。结果还突出了技术变化的重要性以及省/地区特定特征在确定温室气体排放水平方面的重要性。
