The issue with carbon emissions from burning fuel is that they increase the carbon in the atmosphere because their origin is from sources trapped underground. Similar to a water cycle there is a carbon cycle. The carbon we exhale is produced from biological processes, not from combusting carbon which was previously trapped.
Edit to say, don't be like me. Read the source material before you react. Or at the very least read the comment to my post.
tldr: i'm not the one making these ridiculous claims, it was a statement made (apparently in earnest) by a loopy politician.
“You would be giving off more CO2 if you are riding a bike than driving in a car,” he said. However, he said he had not “done any analysis” of the difference in CO2 from a person on a bike compared to the engine of a car" 😂
Unless you're consuming fossil fuels as your daily lunch... the co2 you produce is netural (well excluding the emissions created during farming and logitics of getting your food to your dinner plate). But thats getting very pendatic.
