I don't want to start a war here, but what do people who know about such things think of this. It isn't really news. This carbon credits scam was identified 5 years ago and now industry is kicking back against attempts to prevent abuse. They were making more money by making the impurity and trading credits than by selling the end product refridgerant. Utter policy madness!

Another point about this is that HFC-23, which is nothing more than trifluoromethane or fluoroform (CHF3) is, according to my knowledge, not a substance that destroys the ozone layer though it certainly chemically resembles those that do. Its production is therefore limited by fewer protocols than a known ozone-depleter.

All the HFC compounds are less enduring than the ozone depleting CFCs
that they replaced and degrade somewhat more rapidly in the atmosphere.
However, this one is a very potent GHG and relatively stable.

It is a few thousands of time more effective as a GHG than CO2 and stays
around for about a half life of 300 years.

Not a good idea to be pumping it out just for the hell of it.

The carbon credits market is corrupt and corrupting and has become
nothing more than a vehicle for spivs and speculators and merchandise
free carousel fraud. Basically just what you expect from bankers.
