      All air travel, all of it, amounts to less than 3% of carbon emissions.

            So if we make up some 30 more categories with as much emission as air traffic, none of them make an impact, because they are all only about 3% of the total?

                Let’s see: 30*3 = 90

                We have room for 3 more categories, and then some!

                They are all small, but they still make up 100%

                  That is not how percentages of an existing number work. C’mon man.

                  I have 100 sandwiches. 3% of them contain mayo. If I break that total up into all manner of groups 3% of them still contain mayo.

                  Atmospheric carbon is measurable and we know how much of that number is released by various causes. Adding other causes will not change these percentages - the added causes will just be smaller fractions of percentages that exist.

                    I had to re-read it a few times, but I think they are trying to say if the other 97% is divided into 30 categories they will all be about 3% also. The implication being that every percent counts.
