Green Toolkit

Green Toolkit is a verified system for CO₂ and ESG reporting in film and media production. We combine data collection, ISO 14067 methodology and certified audit workflows to make sustainability measurable — from individual productions to entire organisations. Developed by GWK Grüner Werkzeugkasten GmbH (Cologne) and Green Toolkit Inc.(New York), the platform is used by studios, broadcasters and production companies to generate ISO-compliant CO₂ data, manage ESG indicators and create audit-ready reports. Our approach bridges practice and policy: we translate international standards such as ISO 14067 and the GHG Protocol into practical tools and training systems that fit real production workflows. Green Toolkit is fully bootstrapped and independently developed — trusted by partners including Red Bull Media House (Servus TV, Terra Mater Studios, Red Bull Global Media Services and Red Bull Studios), and A24, when it comes to delivering measurable, verifiable sustainability across the audiovisual industry. From Cologne to New York — and back again.
