Introduction

As the world accelerates toward carbon neutrality, measuring and managing carbon absorption in forests has become a critical challenge. Toho Gas has unveiled an innovative approach using artificial intelligence (AI) to analyze how much carbon dioxide (CO2) trees absorb. By combining cutting-edge AI technology with drone surveillance, this initiative aims to make forest carbon measurement more accurate, efficient, and accessible—while supporting national carbon credit systems.

AI-Driven Forest Measurement: A New Era

On October 27, Toho Gas conducted a public demonstration in Mitake Town, Gifu Prefecture, showcasing how AI can track and quantify the CO2 absorption of trees. The project utilizes technology developed by DeepForest Technologies, a startup originating from Kyoto University, which analyzes drone-captured images to determine tree height, species, and density. The data collected can be applied to Japan’s national CO2 emission credit system, known as J-Credit, allowing forest owners to participate in carbon trading with minimal effort.

Drone Technology in Action

During the experiment, drones flew approximately 100 meters above a 10-hectare forest area, capturing images in just 10 to 15 minutes. This method significantly reduces the labor and cost associated with traditional forest measurement, making it easier for landowners to quantify the environmental value of their forests. A spokesperson from Toho Gas explained that the initiative aims to “visualize the environmental value of forests” while promoting sustainable management practices.

Expanding Applications and Future Prospects

DeepForest Technologies is also testing its AI measurement tools in other regions, including Toyota City in Aichi Prefecture, with the goal of improving forest monitoring capabilities. By 2024, the company has been selected for Aichi Prefecture’s “Aichi Environmental Innovation Project.” Beyond CO2 absorption, this technology can predict tree falls and assess overall forest health, offering broader ecological and safety benefits.

Carbon Zero and Global Context

As nations strive to achieve carbon neutrality, technologies like AI-driven forest monitoring are becoming increasingly important. They complement efforts in electric vehicles, renewable energy, and energy storage systems, providing precise environmental data to inform policy and investment decisions. Efficient measurement of carbon sequestration in forests not only supports national climate targets but also empowers local communities to participate in the global fight against climate change.

What Undercode Say:

Toho Gas’s initiative represents a significant leap in environmental technology by merging AI with drone-based forest management. Traditional methods of assessing carbon absorption are often labor-intensive, requiring ground surveys that are time-consuming and costly. By using AI to analyze aerial imagery, the process becomes faster, more accurate, and scalable across different forest types and regions.

The partnership with DeepForest Technologies leverages academic research for practical, commercial applications. This bridge between startup innovation and established industry provides a model for other utilities and corporations looking to enhance sustainability efforts. AI-driven forest analytics could revolutionize how forest owners approach ecosystem services, enabling more informed decisions about conservation, timber management, and participation in carbon credit markets.

The use of drones flying at 100 meters over large forest plots allows for comprehensive data collection within minutes, highlighting the efficiency gains possible with technology. Beyond CO2 measurement, predictive models for tree health and fall risks offer a dual benefit: environmental monitoring and forest safety management. Such capabilities are particularly relevant in disaster-prone areas where early detection can prevent economic and ecological losses.

On a macro level, this initiative strengthens Japan’s environmental strategy. By streamlining the creation of J-Credits, the program incentivizes private forest owners to invest in sustainable practices. This approach also aligns with global carbon trading trends, where accurate measurement and verification of carbon sequestration are vital for credibility.

Moreover, AI in forestry represents a convergence of multiple fields: computer vision, environmental science, and drone technology. The scalability of this system means that even small or remote forest owners can participate, democratizing access to carbon markets. This can accelerate nationwide adoption of carbon-neutral initiatives, contributing significantly to Japan’s goal of net-zero emissions.

The potential economic impact is also notable. Reduced costs for forest measurement may lead to increased participation in carbon credit schemes, boosting local economies. Additionally, technological innovation in environmental monitoring can foster new business models and job opportunities in AI, drone operations, and data analysis sectors.

Environmentally, the program could create a feedback loop: improved forest monitoring encourages better forest management, which in turn enhances CO2 absorption and ecosystem health. Over time, this could transform Japan’s forested landscapes into optimized carbon sinks, making a measurable contribution to global climate mitigation.

From a technological perspective, integrating AI models with drone imaging datasets opens possibilities for real-time monitoring and predictive analytics. For instance, AI could identify stress in trees due to pests or disease, offering early intervention solutions. Such granular data empowers policymakers, researchers, and private stakeholders alike, bridging the gap between raw environmental data and actionable strategies.

This initiative also reflects a broader trend: leveraging AI to quantify and monetize ecosystem services. Beyond forestry, similar approaches could track soil carbon, wetland restoration, or urban green spaces, creating a holistic framework for carbon management and environmental accountability.

By combining academia, startups, and industrial powerhouses like Toho Gas, this project sets a precedent for collaborative innovation. It demonstrates that achieving sustainability is not merely about reducing emissions but also about measuring, optimizing, and monetizing natural processes efficiently.

In essence, AI-driven forest measurement transforms carbon accounting from an abstract concept into a tangible, actionable tool. This not only supports climate goals but also incentivizes sustainable forestry, creating economic, ecological, and social value in tandem.
