Organizations Involved

CarbonCheck, a leader in carbon validation and verification services, sought to overcome persistent challenges with its outdated WordPress website. The legacy platform was plagued by limited content governance, low user engagement, and a rigid structure that constrained both scalability and operational efficiency. 

To address these issues, OpenSense Labs designed and implemented a modern, scalable solution powered by Drupal 9, emphasizing modularity, structured content, improved workflows, and optimized performance. The result was a measurable uplift in traffic, improved user experience, and a substantial 40% reduction in development costs.

Why Drupal was chosen

A comprehensive technical assessment revealed significant limitations in CarbonCheck’s existing WordPress setup, including: 

  • Over-reliance on hardcoded templates 
  • Lack of reusable UI components 
  • Absence of role-based content workflows 
  • Non-compliance with WCAG 2.1 accessibility standards 

Given these findings, Drupal 9 was selected for its: 

  • Decoupled architecture 
  • Granular permission control 
  • Modular ecosystem for scalability 
  • Strong support for accessibility, structured content, and editorial workflows 

Drupal offered the best balance of performance, flexibility, and future-readiness for the client’s needs.
