A Streamlined Workflow for DMA2 Compliance

1. Generate A1–A5 baselines with minimal inputs 

Using the Urban Mining Screener, teams can create credible embodied-carbon baselines from: 

• location 
• floor area 
• asset type 
• construction year 

These baselines meet the level of detail required under DMA2 and work for both individual assets and portfolio-level analysis. 

2. Refine results when more project data is available 

Where additional data exists,  such as material quantities, construction specifications or EPDs, teams can strengthen and update the baseline. This keeps workflows efficient while improving accuracy for assets with richer information. 

3. Export GRESB-ready evidence 

Madaster produces: 

• A1–A5 embodied-carbon results 

• outputs aligned with DMA2 reporting structure 

• transparent, traceable evidence packages 

If an asset is already modelled in Madaster, the embodied-carbon evidence can be exported directly. Additional refinement is optional, not required. 

How Different Stakeholders Use This

Owners and Institutional Investors – Portfolio-Level Carbon Visibility 

Madaster enables owners to benchmark assets, model decarbonization scenarios, identify transition risks and align embodied-carbon reporting with EU Taxonomy and other regulatory frameworks. This converts embodied carbon into a strategic performance metric rather than a standalone disclosure. 

Fund and Asset Managers – Efficient GRESB Reporting 

Managers responsible for GRESB submissions gain a consistent, repeatable workflow for DMA2, with standardized outputs, structured evidence files and easy exports (Excel, PDF, API). This reduces dependency on bespoke LCAs and simplifies annual reporting cycles. 

Consultants and Advisory Partners – Scalable, Repeatable Workflows 

Consultants can build a repeatable embodied-carbon service for multiple clients using the same workflow. Rapid baselines, consistent modelling and clear evidence packages help deliver value at both asset and portfolio scale. 

How Madaster Reduces Complexity

Standardized results aligned with DMA2 

Outputs follow GRESB’s structure for upfront carbon reporting, reducing variance across projects, consultants and regions. 

Designed for portfolio scale 

Baselines produced in seconds allow teams to prepare early, refine progressively, and manage reporting across multiple projects and countries. 

Evidence suitable for validation 

Results are transparent and traceable, helping teams meet GRESB’s documentation and review expectations as embodied-carbon regulation and audit scrutiny increase. 

A unified environment for long-term value 

All building data remains in one place, enabling reuse assessments, circularity metrics, ESG dashboards, financial planning and strategic portfolio management. DMA2 becomes part of a wider material and carbon strategy — not an isolated calculation. 

Prepare Now for the 2026 GRESB Cycle

The GRESB assessment follows an annual cycle. The portal opens on 1 April, with submissions due by 1 July. Participants receive preliminary results in September, followed by final scores in October. 

Teams that prepare now can establish baselines ahead of the new cycle, refine data as projects progress and avoid the pressure of the reporting window. This puts them in a stronger position to submit complete, credible evidence and capture the available points. 

Madaster already supports GRESB workflows in seven countries and is used by leading banks, asset owners and fund managers to improve the ease and consistency of embodied-carbon reporting.
