If they move 3,000 blades for ~10MW turbines then a 20% improvement in capacity factor alone is worth 3,066,000 metric tons of CO2 year. Edit: (Ops 10Mw * 1,000 turbines * 0.5 tons from natural gas /MW * .35% capacity factor * 20% improvement * 24 * 365 hours, coal is roughly double that.)
Assuming: 500tons of fuel for the transport of the 3 blades (comparison: AN225 with higher max payload weight guzzled ~15tons/hour).
You could have used that energy to produce 500000kg * 40MJ/kg * 40% = 8TJ.
The turbine would need ~40d to produce this (~25% capacity factor, 10MW nameplate power):
The existing option is semi trucks traveling in daylight with additional vehicles supervising and special self steering trailers, local PD stopping traffic if necessary, new roads being built or existing ones improved.
By comparison a commercial jet takes ~20 years to emit 1 million tons of CO2. https://www.reuters.com/business/aerospace-defense/boeing-je...
