I am redesigning an old greenhouse gas emissions regulatory application that has a common design pattern where data tables include "Not Applicable" marked as N/A as the first column. When the user marks a row as N/A they are essentially saying that the particular emission does not apply and the system will not use the information in that row to perform different calculations and it also is useful for data extraction purposes. This approach does not seem intuitive and I've been trying to think of alternatives.

The obvious solution that comes to mind is to make it an opt-in approach vs an opt-out (what it is currently). So remove the N/A and only if the user deems it applicable, they will click on the checkbox marking that it applies. This approach might not be the best because we want the use to consciously read through each emission and mark it as N/A. It's an extra layer of validation. If we don't force the user to do this, they might not make the effort to mark relevant emission as applicable.

Another option we have thought about is to make the user enter a zero instead of an N/A checkbox, but zero and N/A serve different purposes. Zero would mean it is still applicable but the emission is zero.

Screenshots attached.

Is the N/A approach they way to go or is there a better solution?

    Interesting. First question: how many possible options/rows/items are there that the user can select from (or designate as N/A)? Second question - what are the steps just before and just after this, for some context?

  • Would it be an option to let users remove the non-applicable rows, with the option to add them again from a dropdown menu?

  • #1 It depends. Some tables have 3...some can have 20. #2 no "steps" before these pages. There is a main dashboard page, and then you click into a page that can have multiple data tables like these.

  • I think we could but some of these tables are large. Not sure if that would make dropdowns really long.

  • Do users always make changes to all applicable substances? Can making no changes mean the substance is N/A?

My suggestion is to somehow gamify the process of declaring emissions:

  1. Reverse the N/A into applicable by default, with all items selected.

  2. Encapsulate each row into a card and place the applicable checkbox as a partial overlap with the card (either center-left or top-left of the card). Make it look like a fancy checkbox (rounded, big, colorful etc.)

  3. When deselecting the checkbox, disable all inputs inside the card and make the whole card grayed out.

  4. When refreshing the page, place the unselected cards at the bottom of the list.

  5. Maybe you can even drop the table layout and display the cards in a grid.

  6. Add a title above each list of cards and also add in brackets how many cards are selected, like this: "Toxic emissions (4 selected)". By default they should all be selected to encourage the user to think about them.

  7. You can move the sub-total next to the title and make it bigger, to draw attention to the overall impact and encourage users to reduce that number.

  8. Use various colors, backgrounds, badges, icons, illustrations for each card based on the provided user input (big emissions = red, small emissions = orange, 0 emissions = green, etc.). When refreshing the page, place the large emissions first, to draw attention to them.

  9. Add a progress bar based on how many cards are selected vs how many are considered "safe" emissions. Place the progress bar on top of the list and make it obvious.

  10. If all selected cards are emissions at toxic levels, add a dummy emission that is safe, so that you can always have a small progress in the progress bar. This will nudge users to fix the other emissions.
