I liked the conclusion of this piece -- looking at the total impact of your actions is what's key:

"“If you don't want to make this a side hobby and you're willing to spend some money to address your impact, ask yourself, ‘How can I make the biggest systemic difference? How can I invest in social or political or policy change?’” he said. “What you should brag about is not that you're carbon neutral. You should say, ‘I donated $100 to something I believe in.’”

After all, there’s nothing wrong with wanting to take responsibility for your emissions, but climate change is a system-wide problem that requires system-wide changes. And there is more than one way to be a part of that change—whether or not you get a certificate for your contribution."
