What is 200 gt?

200 GT stands for 200 gigatons, which is a unit of measurement for carbon dioxide emissions. One gigaton is equal to one billion metric tons, and therefore, 200 gigatons of carbon dioxide emissions represent the amount of greenhouse gases that the world needs to reduce to mitigate the effects of climate change. It is estimated that current carbon dioxide emissions are around 36 gigatons per year, which means that the world has approximately five years to reduce carbon dioxide emissions by 40-50% to limit global warming to 1.5°C. Failure to reduce emissions will result in catastrophic consequences such as rising sea levels, more severe weather events, and extinction of species.
