政府推行征收费用，转眼超过8年。环保署不时搬出亮丽数字，强调政策成功减少「胶祸」。近日环保署披露，2016年胶袋弃置量反弹，升见4年最高，当局对胶袋征费成效是否太过乐观，值得关注。政府评估政策成效，不能偏看有利于己的数字，必须时刻留意蛛丝马迹，检视政策漏洞。胶袋征费效力再惹怀疑，政府需要切实检讨，亦要反思处事心态。 The government has implemented levy for more than 8 years. From time to time, the Environmental Protection Department puts out bright figures to emphasize that the policy has succeeded in reducing the "plastic disaster". Recently, the Environmental Protection Agency disclosed that the amount of plastic bag disposal rebounded in 2016, rising to the highest in four years. Whether the authorities are too optimistic about the effectiveness of the plastic bag levy is worthy of attention. When evaluating the effectiveness of policies, the government must not be partial to figures that are beneficial to itself. It must always pay attention to clues and check loopholes in the policy. The effectiveness of the plastic bag levy has raised doubts again, and the government needs to conduct a thorough review and reflect on its mentality.
