- oldandtired 9y agoWhich is relevant in what way? The amount of concrete is small in relative terms, so doubling a small quantity is still a small quantity. A forest fire will put out significantly more CO2 and they occur quite frequently around the globe. If you want us to take your comment seriously, you will need to show that the CO2 emissions would be on some significant level.
