Every year Oxfam explores the status of climate inequality globally. Our report published in October 2026 makes the overlap between the inequality and climate crises clearer than ever.
What is the latest report?
Key points
- A person from the richest 0.1% has contributed x125 more than the average person to extreme heat events ... almost x400 more than someone from the poorest 50%.
- The global disaster recovery market is forecast to grow from US$70bn to US$92bn a year by 2029, increasingly fuelled by climate-related extreme weather events.
- Between 2014 and 2050, 1 billion people – around 10% of the world’s population – will have been displaced by the climate crisis. And most of those displaced will be in the Global South.

The world’s richest 0.1% have contributed 125 times more than the average person to extreme heat events and almost 400 times more than someone from the world’s poorest 50%. Just one year of emissions by the wealthiest 1% of the population will cause almost 2 million excess heat-related deaths worldwide.
