🗞️ Driving the news: A new MIT Sloan study finds that voluntary carbon credit prices are driven more by buyer preferences and perceptions than by the actual climate impact of the projects behind them

🔭 The context: Researchers analysed more than 7,200 carbon credit transactions between 2018 and 2024, covering around 11% of the global secondary voluntary carbon market
• The study examined purchases from 1,200 companies across sectors including finance, energy, manufacturing and consumer goods
• The findings challenge the idea that carbon credits function like a standard commodity
• Similar credits linked to the same amount of emissions reductions were sold at vastly different prices depending largely on who purchased them and the narrative associated with the project

🌍 Why it matters for the planet: Carbon markets are designed to direct capital toward effective climate solutions
• If pricing rewards visibility and storytelling over measurable climate impact, investment may flow away from the technologies with the greatest emissions reduction potential
• Improving transparency, quality standards and price discovery will be critical for carbon markets to become a credible tool for financing the transition

⏭️ What’s next: Researchers are calling for greater market transparency, including public price benchmarks and improved reporting of transaction data
• As companies face increasing scrutiny over climate claims, demand is expected to shift toward higher-integrity credits with clearer environmental outcomes

💬 One quote: “To really make the market function well, it’s very important that we create a mechanism to make it more transparent.” - Florian Berg, Principal Research Scientist, MIT Sloan School of Management

📈 One stat: Buyer identity explained 62% of the variation in carbon credit prices, according to the MIT study
