According to Neal Tognazzini and D. Justin Coates, the issue of hypocrisy with regards to blame involves "standing to blame":
There has recently been an explosion of work on the so-called standing to blame, which is often taken to be the primary fact about the blamer that is relevant to whether an instance of blame is appropriate. Hypocritical blame is usually treated as a paradigm example, and the most basic thought is simply that there seems to be something inappropriate about blame issued by a blamer who is guilty of the same transgression to which they are reacting. The standard way of talking about what’s going wrong in this sort of case is to use the label ‘standing’: the hypocritical blamer lacks the standing to blame.
Blame is a form of social disapproval that people wish to be avoid. The hypocrite's blame may itself be morally wrong:
...the hypocritical blamer—as long as they aren’t also blaming themselves, in which case they might not count as hypocritical—treats their own interest in avoiding blame as more important than the interest of the target of their blame. As Wallace puts it (2010: 328): “This offends against a presumption in favor of the equal standing of persons that I take to be fundamental to moral thought”. Thus, for Wallace, the problem with hypocritical blame is that it is morally wrong (and thus inappropriate even if the target is blameworthy). [my emphasis]
Let's consider the OP's question whether some scenarios involve hypocrisy. Here is the first example:
Being pro climate protection while not doing ANYTHING to stop it yourself (such as saving energy etc etc.
Is the person taking the pro climate protection position blaming someone else?
Suppose Jane votes for a pro-climate position on a ballot and she does not blame anyone for taking a different position than she does. Is she a hypocrite if she does not switch to energy-efficient lighting in her own home? Since she is not blaming anyone, she would not be involved in hypocrisy. Blaming her for hypocrisy may itself be inappropriate.
Suppose Bill not only votes for the pro-climate position on the ballot, but also blames other people for not switching to energy-efficient lighting. If he does not himself switch to energy-efficient light, his blaming might be hypocritical. He may be considering his "own interest in avoiding blame as more important than the interest of the target" of his blame.
