Message from the CEO
The accelerating pace of climate change is something we all feel acutely. From intensifying natural disasters to rising global temperatures, it’s clear that achieving a decarbonized society is no longer an option, but a necessity.
While the path to decarbonization sometimes falters, leading to divisions, we remain steadfast. Our mission is to pursue both decarbonization and economic growth simultaneously. To achieve this, we’re keenly focused on leveraging nature-based carbon credits.
What sets our projects apart is our unique strength in collaborating with a wide range of stakeholders. This includes local government officials, hardworking farmers on the ground, and private companies who are the end-users. We firmly believe that for a project to be truly sustainable, it must be designed to benefit all participating stakeholders.
Operating in a field with few precedents, we are constantly pushing forward with unwavering dedication to ensure our projects succeed. Stepping into such an environment might present challenges, but it’s precisely this experience that will foster our growth, empowering us to become a catalyst for global transformation.
We are committed to this journey, tirelessly working to create a more resilient and equitable world. Together, we will continue to pioneer innovative solutions and move forward towards a truly sustainable future for all.
