Since this is not my area of expertise, I searched Google under the key words "environmental sustainability" to get these possible sources:
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
Since I don't know your situation, I can't suggest how you threaten environmental sustainability or how you could change your behavior. You should be able to determine this by know the meaning of the concept.
I hope this helps. Thanks for asking.
