Global investment in the clean energy transition grew by 17% in 2023, showing resilience despite geopolitical tensions, high interest rates, and inflation. But was it enough to keep the world on track to hit net zero by 2050? To answer this question, we compare 2023 clean energy investment by sector with what’s annually needed to reach net zero by 2050, in partnership with the National Public Utilities Council.

Extrait dans une quinzaine de pays et utilisé comme combustible pour les réacteurs nucléaires, l’uranium provient en majorité d’Amérique du Nord.

Épuisement des ressources, infrastructures vétustes ou inadaptées, mauvaise qualité de l’eau... Une large partie de la population mondiale est en situation d’insécurité hydrique.

Mapped: Carbon Dioxide Emissions Around the World According to Our World in Data, the global population emits about 34 billion tonnes of carbon dioxide (CO₂) each year. Where does all this CO₂ come from? This graphic by Adam Symington maps out carbon emissions around the world, using 2018 data from the European Commission that tracks tonnes of CO₂ per 0.1 degree grid (roughly 11 square kilometers). This type of visualization allows us to clearly see not just population centers, but flight paths, shipping lanes, and high production areas. Let’s take a closer look at some of these concentrated (and brightly lit) regions on the map.

The current energy transition is powered by the realization that avoiding the catastrophic effects of climate change requires a reduction in greenhouse gas emissions. This infographic provides historical context for the ongoing shift away from fossil fuels using data from Our World in Data and scientist Vaclav Smil.
