CO₂

Installations and projects, with the figures their owners reported
A case study here is one project, taken apart with the numbers behind it. Every figure carries what it was measured against, how it was measured, over what period and who produced it, so you can judge the claim rather than take it. Companies pay for these and we write them from what they supply: that is stated on every one, because a reader who knows the terms can read the engineering on its own merits.
