"The purpose of this Discussion Paper is to seek feedback on the principles that might guide how best to incentivise transition to net zero via the Corporate Bond Purchase Scheme (CBPS); and the tools we might use to do it. It highlights some of the key challenges and design choices we will need to grapple with ahead of implementing any changes later this year, setting out a number of questions on which we would be especially interested to hear views."--Extracted from Bank of England website
