At the following link is a just released article on logging and carbon storage in forests from the University of Vermont.

As common sense would suggest and that which the report confirms...
1. No logging will produce the most carbon sequestration
2. The next best option is single tree selective logging
3. The worst carbon storage option is clearcutting
See figure 3 on page 8 for comparisons of different management regimes.....
According to the report:
"even with consideration of Carbon sequestered in harvested wood products, unmanaged northern hardwood forests will sequester 39 to 118% more C than any of the active management options evaluated. This finding suggests that reserve-based approaches will have significant Carbon storage value.”
