Earth hacks Launches 'DECARBOOK', a New Web Content Platform Promoting 'Decarbo' Through Lifestyle and Culture

Earth hacks Inc. (Headquarters: Shibuya, Tokyo; President and CEO: Sumito Sekine), which operates a consumer co-creation platform aiming to develop decarbonized products, services, and businesses based on consumer insights, has launched 'DECARBOOK', a new web content platform to make decarbonization more familiar and enjoyable.

DECARBOOK introduces people, products, ideas, and places from the perspective of 'Decarbo' (decarbonization), utilizing angles such as entertainment, lifestyle, and culture. The platform aims to provide opportunities for people to perceive environmental consideration as an extension of daily fun and comfort, rather than as sacrifice or obligation.

By making decarbonization a natural part of daily life and visualizing the environmental efforts of companies and brands, the platform creates opportunities for consumers to 'love what they choose even more.' With this vision, DECARBOOK was launched.

DECARBOOK shares moments where a sustainable society overlaps with human joy and excitement, focusing on entertainment, lifestyle, culture, and the human drama within.
