Last August, MDN told you about a new Cambridge University study published in the journal Science exposing the sale of carbon credits as a scam (see Cambridge Study Finds Carbon Offsets Using Trees is a Scam). After the carbon credit scam was exposed, major companies like Shell, Nestle and Gucci exited the market and refused to spend money on so-called solutions to global warming (see With Carbon Credits Scam Exposed, Big Names (Like Shell) Exit market). How big is the scam? Try almost $1 trillion per year (see Global Carbon Credit Market is $909 Billion Dollar Scam). But you know the left: they don’t give up. The latest tactic is to put some new lipstick on the carbon credit scam pig by using the ‘high integrity’ label to make it look nice.
