I measure impact manually by reviewing the pictures of impact that get submitted through the main post that gets put on on X on the 21st of every month. I ask people to use the hashtag MonthlyEarthDay so I am able to easily find the proof of impact if it is not submitted to the main post.

I then write down all of the submissions, mainly so I am able to give recognition during the space that I host on the 23rd but also so I can count up the impact and add them to the totals for each category.
