On Current CO2 Emissions

Thinking about units, numbers, and measurement of CO2 led me to think about current CO2 emissions, and especially how much we would have to decrease them by and when. According to the Presidential Climate Action Project, “In order to stabilize CO2 concentrations at about 450 ppm by 2050, global emissions would have to decline by about 60% by 2050. Industrialized countries greenhouse gas emissions would have to decline by about 80% by 2050.”(There are a lot of really good numbers and statistics in this document, and they’re all stated very clearly, so I urge everyone to check out the link above.) Basically, to only stabilize CO2 concentrations(not even decrease them!) we would have to globally reduce CO2 emissions by 60%.  In 2020, according to the Global Carbon Project, 36.4 billion tonnes of carbon were emitted. To cut back by 60% globally, we would have to go from 36.4 billion tonnes of carbon per year to 14.56 billion tonnes of carbon per year, if my math is correct. Emissions haven’t been that low since 1970, according to the Global Carbon Project chart I previously linked. Definitely a big step to take in just 28 years!

  3. That is a lot of carbon dioxide that we have to cut out; I wonder if there are any plans for how we could cut back on these emissions fairly quickly? So far it does not seem like any world leaders have implemented plans to do this.
