Drastic Partner joins COP30 delegates for International Green Solutions Award nomination

Drastic partner Produktif joins around 60 hopeful entrants to the prestigious international round of Construction 21’s Green Solutions Awards 2024-2025, which will be announced on 12 November 2025 at COP30 in Belém, Brazil.
A prestigious nomination
The renowned competition has seen 194 sustainable buildings, districts, and infrastructures entered from 26 countries, with the remaining 60 entrants still in the running after passing the awarding body’s national qualification stage.
The Ice Box Challenge 2024
Produktif’s work on the Ice Box Challenge, Oslo, 2024 offered a striking preview of just one of the many circular innovations driving the Drastic project. Using the Ice Box Challenge as a chance to test and demonstrate the same patented Design for Disassembly (DfAD™) technology and ‘C-Joint’ system that will feature as part of Drastic’s Norwegian Demonstrator, Produktif built a highly efficient Passive House mini-home from reclaimed wooden materials, supplied by fellow Drastic partner, Omtre.
In a head-to-head test against a standard-code house, the Passive House retained 150 kg of ice after 33 days in the blistering Norwegian summer heat, whilst the standard-code house’s ice melted completely within just 11 days—proving the exceptional insulation and circular design potential of Drastic-aligned construction methods.
The project, co-organised by Produktif alongside A2M Architecture, hub.brussels and Rexylience, captured both public and professional attention—earning Produktif two Green Solution Awards from Construction21 International, in earlier rounds of the same competition.

Building to COP30
As the world prepares for COP30, the focus is firmly on turning climate pledges into practical action. Here, Drastic is taking the lead, by aiming to demonstrate how the building sector can cut carbon emissions, boost circularity, and make sustainable construction both achievable and affordable across Europe, and beyond.
While COP30 will hopefully push countries to move from promises to implementation, Drastic offers a real-world example of what that might look like on the ground. Via pilot projects across five European countries, Drastic is testing how buildings can achieve deep cuts in whole-life carbon—from materials and construction to operation, multi-life cycle assessment frameworks and end-of-life reuse.
This hands-on approach mirrors the action not words message that will dominate COP30, as the European Union (EU) and its partners look for credible models to support their updated climate targets.
