Carbon offsets are propaganda at best, but actually intended for large Greehouse Gas emitters to use accounting tricks to ensure they don't have to change anything about their business, and show they are complying with the toothless regulations those same industries lobbied the EPA to ratify.
By even participating in the scam you are perpetuating more climate destruction. If you want to "offset" your carbon footprint, go bomb a pipeline. The amount of disruption you cause will probably offset your entire life's carbon output.
