That assumes keeping temperatures below 1.5C, and no negative emissions technologies. In reality, likely this number will slip to 2C, and some negative emissions will be assumed. That brings us to the Paris emissions reduction pathways, which are very achievable with shared global effort. The more we can eliminate the need for negative emissions, the better. But we shouldn’t assume no negative emissions, and the most stringent temperature pathway, otherwise people will just assume that action is impossible and use it as an excuse to do nothing.
