It's easy for people who are not very familiar with carbon accounting or climate change science to use this system, it really helps organize all of your information into one place (and then makes things more manageable).
I have no complaints as far as functionality goes; however, there could be some improvements in terms of user interface (the dashboard can feel overwhelming at first glance), but they're working hard on improving this. We've used other programs like this before, but this was the best so far - we were able to find everything right away!
