The voluntary carbon market has surged, with a value nearly quadrupling to $2.1 billion in a year, reflecting a growing interest in offsetting emissions through carbon credits. Approximately half of these credits are dedicated to reforestation. Aviation contributes nearly 3% of global emissions, and tree planting is regarded as an effective means to counteract this. However, determining the legitimacy and effectiveness of carbon offset projects remains complex, with costs varying significantly. Experts note that while cheaper options exist, true environmental impact often requires a higher investment per ton of CO2.
"On average it usually costs about $20 to $30 a ton to really have an impact if you're going to be either planting trees or taking a forest out of timber production..."
"Planting enough trees to compensate for those emissions would cost around 100, or 22 per ton of CO2 according to that same estimation."
