Young activists are reviving the long-running discussion about climate justice. The discourse frames global warming as an ethical rather than strictly environmental concern.

According researcher Dr. Bjoern Soergel of Germany's Potsdam Institute for Climate Impact Studies, the move to net-zero could result in higher food and energy costs, which would disproportionately affect the poor.

However, he claims that there is a "win-win" scenario in which the environment can be protected while global poverty is reduced. Carbon taxation - basically a carbon tax on polluting fossil fuels - will be implemented, with states redistributing part of the gains per capita.

Richer nations will then have to donate a percentage of their wealth to countries of severe poverty.

According to Harriet Lamb, policies aimed at encouraging healthier, greener living risk exacerbate current socioeconomic divides and derail a net-zero planet's transition.

Although climate injustice has been discussed for decades, it is now being given new life by younger activists.
