Grégory Claeys, Simone Tagliapietra and Georg Zachmann researchers of the Bruegel Think Tank propose a three-phase approach:
1º Creation of a high carbon tax
2º Investment willing to favour green companies
3º Funding disruptive green initiatives by the industry
Still, I believe that it may risk being a very modest strategy in the context of what is mentioned in the links below. Let´s not forget that "the house is on fire" meaning that we need strong and very effective measures not just the business as usual agenda !
1º Creation of a European criminal court to trial extremely high corporate polluters like these ones https://www.gazettenet.com/UMass-researchers-list-country-s-top-water-air-greenhouse-gas-polluters-27421770
2º Putting in place a prohibition regime that forbids European countries to do business with extremely high corporate polluters
3º Creation of a European penal code to include offenses like the ones mentioned in here
Post-scriptum - If Europe already has a (wonderful) International Criminal Court at Hague (that USA dislikes) there´s no reason it can have also a court to trial corporate polluters even because corporate polluters also kill people, a lot of people. According to WHO air pollution alone kills 4 million a year
