The article discusses how a program called the Clean Development Mechanism (CDM) has issues in meeting its goals. It's used by some companies in Europe to offset their pollution by funding eco-projects in poorer countries. Findings show that many projects funded by CDM wouldn't need this support. This could've added millions of tons of CO2 emissions in recent years. Some projects are way costlier under CDM than if tackled directly. Plus, it's uncertain if these projects really help poorer nations. Instead of boosting green tech in developing countries, CDM could actually hurt their move towards cleaner energy. Surprisingly, using CDM credits can reduce greenhouse gas cuts required in Europe by 2020.
