In recent years, the voluntary carbon market has been challenged by a lack of transparency and quality, leading to skepticism about carbon credits as an effective tool to combat climate change. At Amazon, our scientists aim to address these challenges and work with third-party experts to monitor, measure, and ensure the validity and integrity of our projects. Amazon takes a “first principles approach”—we identify rigorous methodologies, rather than default to the current standards, and continually revisit the science as technologies and new advancements are made.
