The research shows that there's a problem with how money to fight climate change is shared between rich and poor countries. Wealthier countries promise to help but aren't giving enough or giving fairly. By looking at where money for wind and solar power goes, the researchers found that how good a country is for investing, its economy, and its climate policies affect the funding it gets. Richer countries get more private money, while public money depends on a country's climate goals. Countries that are most affected by climate change struggle to get funds, continuing a pattern of unfairness. To fix this, future plans need to make sure money goes where it's needed most.
