Flooring companies are proud of their green certifications and advertise that prominently. You will NEVER get a quality product or anything approaching "green" at the price point that LL sells their crap at. You can have "cheap" or you can have "green" but you will never get the two together.

"Teak" these days is often cumaru, which is a tropical hardwood that with a high moisture content that translates into checks, and wanes post install when it dries out. Be very very sure that you do the proper tests for moisture content on your subfloor as well as the wood itself. That means using an actual moisture meter, not just waiting for "acclimation" based on time alone.

I would suggest that talking to a local family owned flooring store to find a source of locally milled domestic hardwood, even if it's not "certified" is the greenest choice you can make. It's also the choice with the most impact on your local economy. It's also the choice that will likely give you the highest satisfaction with the material and install as there is more accountability.

Remember, condos will have restrictions on hard surface installs that include installing sound attenuation underlayments, so be sure you get an experienced professional to do the install that understands how to accomplish this correctly. Multifamily living installs are more expensive in the labor department because of the added time and materials.
