The CAC logo is very special. If you are not a fan of chemistry, you might not have guessed that the logo is a representation of a chemical structure. If you are a fan of chemistry, see if you can figure out what the chemical structure is – and we will give you a hint: in terms of the changes in our climate this is one of the most important chemical structures that will impact all of humankind. Since we want to give you the chance to figure this out on your own, we will put the answer in our next FAQ entry. Good luck!
