Technology does have a role to play. Between now and 2030, it would largely be existing technologies in order to have an effect on 2030. Investing in new technologies could have an effect on the net-zero target in 2050, but it would be unlikely that they could essentially be created, deployed, commercialized and put in place between now and 2030 to have a major effect.
New technology is more promising for 2050. Existing technology is more promising for 2030.
