What Earth Hacks does
Earth hacks & Co. (Earth Hacks) is a Tokyo-based decarbonization company that operates the Decabo Score (デカボスコア) system, a marketing and reporting solution that visualizes the percentage reduction in CO2 emissions of a product or service relative to a conventional alternative. Scoring is produced via Life Cycle Assessment (LCA) methodology executed by third-party LCA consultants, yielding an objective percentage figure (e.g., a cited ~10% CO2 reduction for FamilyMart's tearful-eye food-loss sticker versus standard discount stickers) that adopters display on packaging, advertising, and websites. The company positions itself as a 'Decabo Cycle' business that links consumer awareness with corporate environmental effort so that decarbonized products sell better and increased sales drive further decarbonization.
The product portfolio is anchored on the Decabo Score platform and extended by Decabo My Score (individual CO2 calculator), Decabo Challenge (Z-generation co-creation program with ~120 selected from ~4,000 applicants), Decabo Lab (Z-generation sustainable-trend research), and Decabo Action (lifestyle decarbonization guidance built on the Ministry of the Environment's Deco-Katsu database). Distribution-reach extensions include the Roblox game 'Find the Earths' (with Moze Inc., March 2026), the Hello! Project music unit DECA!BEAT ('Watcha☆Future' music video surpassing 300,000 views within two weeks of March 2026 release), and QuizKnock educational material (March 2026). Enterprise customers include Ajinomoto, Suntory, Kirin, Kao, UCC Coffee, Nescafe, MUJI/Ryohin Keikaku, FamilyMart, and Mitsui Fudosan; government customers include Kanagawa Prefecture (secretariat for the 'Kanagawa CO2CO2 Points+' campaign that engaged ~1 million participants and achieved 500.9 tons of CO2 reduction) and Ehime Prefecture. Foundational DNA rests on a Hakuhodo (consumer creativity) plus Mitsui & Co. (business development and social implementation) alliance.
Commercial mechanics blend a professional-services core (consultant-driven Decabo Score calculation, quote-based sales, multi-year contracts) with platform licensing (use of the Decabo label and methodology on packaging and marketing). Pricing is not publicly disclosed; engagement is initiated via contact form. As of April 2026, the system is in use across more than 350 companies and 1,800+ products and services, with leadership composed of President & CEO Sumihito Sekine, Vice President CAO/COO Yusuke Wada, CCO Yusuke Shimizu, and CBO Genta Ito, and a staff of 11–50 at the Shibuya headquarters.

Earth Hacks competitors and assessment
Company assessmentBroad incumbents
- Persefoni: Persefoni is an AI-driven climate management and carbon accounting platform for enterprises, with strong CSRD/SEC alignment. Larger and broader platform competitor for corporate sustainability budget that Earth Hacks targets via Decabo Score implementation services.
- Sweep: Sweep is a sustainability/ESG data platform used by large enterprises for carbon accounting, supplier engagement, and stakeholder reporting. While broader in scope than Decabo Score, it competes for the same corporate sustainability tech budget and is expanding into product-level disclosure — overlapping as a broader incumbent.
- Sphera: Sphera provides enterprise sustainability software, including product sustainability/LCA tools across multiple industries. Its 'Product Sustainability' solutions overlap with Earth Hacks' third-party validated product scoring, but Sphera is a broader portfolio incumbent serving larger global enterprises.
- Watershed: Watershed provides enterprise carbon accounting and disclosure software, positioning itself as a comprehensive climate platform. It competes for corporate sustainability budget against Earth Hacks' Decabo Score service but at the corporate inventory level rather than the product/SKU level.
Direct peers
- Carbon Trust: Carbon Trust is a global sustainability consultancy that performs LCA calculations and issues product carbon footprint labels (the 'Carbon Trust Reducing CO2 Packaging' label). It is the closest Western analogue to Earth Hacks' third-party-validated LCA scoring for consumer products.
- ClimatePartner: ClimatePartner provides product-level carbon labels (the 'ClimatePartner certified' mark) calculated via LCA methodology and integrated into product packaging, advertising, and corporate websites — directly mirroring Earth Hacks' Decabo Score value proposition, customer type (large consumer brands), and consulting-driven delivery model.
- myclimate: myclimate offers product-level carbon labels and consulting-led LCA services for consumer brands, with a strong B2G and co-creation community component (similar to Decabo Challenge). Closely comparable functionally to Earth Hacks' Decabo Score platform and partner model.
Emerging players
- Greenly: Greenly is an emerging carbon accounting SaaS platform with consumer-engagement features similar to Decabo My Score. Slight overlap on the SME-to-mid-market side and product-level carbon footprinting, though focused more on measurement than third-party-validated marketing labels.
- CarbonCloud: CarbonCloud provides product-level climate footprint data and labels specifically for the food industry — a direct vertical overlap for Earth Hacks' food and beverage customers like Ajinomoto, Suntory, Kirin, and FamilyMart, though narrower in geographic reach (primarily European).
- Climate Neutral Certified: Climate Neutral Certified is a product-level carbon label certification brand for consumer goods, directly comparable to Decabo Score's brand-license model. Comparable in scope and value proposition (consumer-recognized carbon label on packaging), though registry/NGO-based rather than LCA-consultant-driven.
