Have you heard about "LCA", aka Life Cycle Analysis? Of course there are emissions during production, anything else is impossible. The question is how much time it takes for the project to "break even".
This is a misperception. Concrete has a much lower carbon footprint than steel pr. weight unit, and comparing a concrete spar towards a similar structure in steel gives a much larger footprint for the steel structure. However, since a large volume of construction projects world-wide (onshore and offshore) are built in concrete, the CO2 footprint from cement production is a fair portion of the worlds total footprint. This is due to the considerable volume. The benefit of concrete structure are also that they are easier to construct locally - and hence avoid long distance vessel transportation.
Great video, thanks. I will keep an eye on the project.

Concrete has a very large co2 and emission footprint. All the ships involved, cables and steel just makes this project laughable...
