Why not? That would effectively bring emissions growth to 0. More carbon would start to be fixed then released into the atmosphere again due to growth in afforestation efforts. Within the next 5-10 years we would start to see negative greenhouse gas emissions growth. It's all about balancing the math so we fix more then is released. Stopping fossil fuel emissions shifts the curve towards fixation and greenhouse gas reductions.

As long as we continue to grow carbon fixation efforts without burning more fossil fuels we should head towards a negative growth trend and 350 ppm again.
