Greta Thunberg blasts John Kerry for claiming ‘50% of CO2 reductions needed…will come from technologies that have not yet been invented’

  • Greta Thunberg responded on Twitter to comments John Kerry made about technology’s role in combating climate change.
  • Thunberg compared Kerry’s statements to the Marvel Avengers.
  • Kerry cited scientific advice on how technological advances will reduce carbon emissions.

Environmental activist Greta Thunberg is speaking out against John Kerry, after an interview in which the U.S. climate envoy expressed optimism that technological advances will help reduce emissions and people won’t have to change certain behaviors to achieve some climate goals.

In a Sunday interview with the BBC, Kerry said technology that has yet to be invented will most likely play a large role in combating climate change — and people won’t have to “give up a quality of life to achieve some of the things we want to achieve.”


“I am told by scientists, not by anybody in politics but by scientists, that 50% of the reductions we have to make to get to net zero by 2050 or 2045, as soon as we can, 50 percent of those reductions are going to come from technologies that we don’t yet have,” Kerry said.

“That’s just a reality,” he added. “And people who are realistic about this understand that’s part of the challenge.”

Thunberg took offense to Kerry’s implication that people do not have to change their lifestyles or consumption habits to help fight climate change.


Thunberg has spoken out against world leaders in the past. The 18-year-old Swedish activist gave an emotional speech at the United Nations in 2019, saying “how dare you,” and expressing how leaders’ empty words and lack of action have stolen her dreams and childhood.

Thunberg also retweeted a response to Kerry from climate scientist Michael Mann.
