The ability to meet humanity s needs without harming future generations is now a top priority in most corporate agenda: ethics, rules, righteousness, sustainability

I think that the question asks whether this aim goes under the name of ethics, rules, righteousness or sustainability - that's how I understand it.

The best answer is "sustainability" because it's a specific word that means that the usage of something today should not impact the ability to use the same thing later (because for example we will run out of it).
