The parliament will decide whether to veto the European Commission's proposal to add gas and nuclear power plants to the European Union "taxonomy", a list of economic activities that investors can label and market as green in the EU.
"We cannot let this happen, otherwise we will be tied to fossil energy long after we should have phased it out," said lawmaker Linea Sogaard-Lidell of the centrist Renew political group and an opponent of the rules. Conservative lawmaker Pernille Weiss, a supporter, warned that failure to incentivise gas and nuclear investments would "tie down the European Union to coal and oil" and make it harder to cut planet-warming emissions.
Others suggest the taxonomy's political symbolism far outweighs the impact it will have on investors, since the law does not prohibit investments in activities without the green label.
