There is growing interest in a "green tax" that would be on carbon emissions. It has been estimated that the median incremental damage to our environment is $14 per ton of carbon, but some estimates go as high as $350 per ton. The average North American generates about 20 metric tons of carbon dioxide each year. This compares to a global average of 4 tons.
Unlike our household garbage, that we can clearly see and measure, it is difficult for most people to be aware of their carbon dioxide emissions. If we are indeed serious about our emissions, we need to start measuring them and tax accordingly.
