Carbon credits for fertilization should not be allowed unless and until reliable methods have been developed to estimate and verify the amount of carbon actually sequestered, and side effects have been properly understood and taken into account. It is essential that each stage of these experiments is reviewed by well-qualified experts free of vested interests.
