VT vs. CRBN

Hi everyone! I am currently 100% VT in my roth IRA right now (Though I am 23 y/o, I have a bond ladder of US treasuries for my bond allocation). ESG investing has its quirks, but I found a global all-in-one low carbon ETF called CRBN that tracks low carbon companies which is pretty cool. It essentially has the same geographical composition and returns since its inception compared to VT. Does anyone hold this and/or have any opinions on this ETF, and is it worth it?
