In its latest report, the IPCC highlights one key solution: sobriety. Here’s a closer look at what that means.

Right now, our climate, ecosystems, and biodiversity are degrading, pollution is constantly rising, and fossil fuel resources are running out. Greenhouse gases, or GHGs, are building up in the atmosphere and driving up global temperatures.
Normally, the Earth naturally emits and absorbs GHGs, keeping itself in balance. However, human activity is now releasing more greenhouse gases than the planet can absorb. This overproduction is what’s driving climate change.
We need to move quickly toward reducing our environmental impact and significantly changing our lifestyles and consumption habits to cut down on greenhouse gas emissions.
The latest IPCC report is clear: we must cut our GHG emissions by 75% between now and 2050 to keep the Earth's surface temperature from rising more than 1.5°C.
A temperature increase of more than 1.5°C would have devastating consequences for all living things: rising sea levels, loss of land, species extinction, wildfires, droughts, food insecurity, and mass migration.
Technologies like electric and hydrogen vehicles, wind turbines, and solar panels help reduce our climate impact, but they aren't without their own downsides. They require the extraction of rare materials and resources. Relying solely on technology isn't enough to solve the greenhouse gas problem.
The key to the ecological transition lies elsewhere: the IPCC proposes sobriety.
The goal isn't to deprive ourselves or reject technological progress, but to rethink what we actually need. It’s not about eliminating needs, but meeting them differently—by avoiding excessive consumption and finding ways to reduce our environmental impact using what we already have.
Sobriety is the combination of developing sustainable solutions and practicing measured consumption for truly useful purposes.
We need to question how we consume: Do we really need to use a private vehicle for every trip? Can we rethink our daily commutes and swap some car trips for greener modes of transport? Replacing gas cars with electric ones lowers our GHG emissions, but it’s not enough on its own—it has to be paired with a real shift in how we get around.
Rethinking urban planning would help limit the need for private transport. Right now, essential shops and services aren't always close to home, and green transport options aren't always accessible to everyone. Expanding public transit would reduce car dependency. Bringing shops closer to homes and transit hubs would make them easier to reach without always needing a car.
In short, we need to keep developing electric vehicles to replace high-emission gas cars, but we also need to rethink our needs by limiting private car use and promoting greener ways to travel.
