CO2 emission calculator

In addition to reducing CO₂ emissions, a carbon price reduces harmful criteria air pollutants from fuel combustion that harm human health . To demonstrate these effects, take this example of a theoretical carbon fee (from Confronting the Climate Challenge).

A new study has identified the four actions that would have the greatest impact on an individual’s greenhouse gas emissions: eating a plant-based diet, avoiding air travel, living car free, and having fewer children .

The Short Answer: Carbon is in carbon dioxide, which is a greenhouse gas that works to trap heat close to Earth. It helps Earth hold the energy it receives from the Sun so it doesn’t all escape back into space . If it weren’t for carbon dioxide, Earth’s ocean would be frozen solid.
