How is a positive number minus zero negative? The carbon scrubber itself can be carbon negative if the carbon is sequestered but that’s true even if the power supplied to it emits carbon. The power source doesn’t get to take credit. That only complicates the math and leads to double counting. I still don’t see how the wind turbine itself is carbon neutral. And even if I did nothing about being made of wood makes a wind turbine more suitable for powering a carbon scrubber. These terms have meaning and overstating the capability undermines credibility.
