Seems like its BS, but lets boil it down to a simple unit example:

Company g pulls 1 unit of electricity from a coal power plant that produces just that 1 unit of electricity. By buying carbon offsets, g indirectly funds a power developer to replace the coal plant with a solar plant.

In this example, offsets produce the same net reduction as building their own solar power plant. As long as you purchase offsets from reputable organizations that require the deployment of proceeds to directly offset carbon that would not otherwise have occurred, then it works.
