"Portugal e a taxa de carbono: milagre ou imbróglio fiscal?"
This essay discusses carbon taxation as a crucial market tool for the energy and climate transition, which several European Union countries, including Portugal, use to reduce carbon emissions. The principle behind this mechanism is that prices should reflect the negative externalities that greenhouse gas emissions cause to society. However, there are several concerns about the effectiveness of this measure, including whether the most polluting companies will flee to countries with lower carbon taxation, whether carbon tax will affect the purchasing power of vulnerable consumers, and the costs of implementation and monitoring. The essay also raises the question of what alternatives exist to deal with the climate crisis.
