What method am I supposed to say I used when I am simply collecting secondary data from other sources?

Great videos, really helped me out but I was wondering. My topic is about the emissions during the pandemic lockdown and if they were reduced by it. I think it's an interesting topic but I wonder if it is good since it isn't repeatable. Any opinions?
