For the past three years, the GRESB Real Estate Standard asked developers to report embodied carbon data from their construction projects. It collected the numbers but didn’t score them. That changed in 2026.

Starting with this assessment cycle, embodied carbon is now a scored indicator in both the Development and Performance Components of the GRESB standard. The shift affects every fund, developer, and asset manager that submits a GRESB assessment: over 2,200 entities covering real estate portfolios worldwide.

A new five-point indicator was added to the Development Component, targeting upfront carbon: the emissions locked into a building before it ever opens, from material extraction, manufacturing, and transport through construction. This is not operational energy. It is the carbon embedded in the concrete, steel, glass, and insulation used to build the structure.

The scoring model rewards entities that measure and document those emissions at the project level. It penalizes those who don’t. Evidence upload is required. Declarations of intent are not enough.

The projected impact is not uniform. For the Development Benchmark, scores are expected to shift between -8 and 0 points, with an average decrease of 5.3 points. For the Standing Investments Benchmark, the expected change is between -2 and +2 points, with a near-zero average effect.

The gap between those two numbers tells you exactly who this affects most: the developer who is deciding right now what materials to specify, what suppliers to use, and whether to run a lifecycle assessment before breaking ground.

This is not a story about sustainability reporting. It is a story about capital access.

The 150 institutional investors who rely on GRESB data represent some of the largest real estate capital pools in the world: pension funds. sovereign wealth funds, and insurance capital. When they evaluate which funds and developers to allocate to, GRESB scores are part of the due diligence.

A drop of 5 points in the Development Component does not disappear from a portfolio. It says there until the next assessment cycle, visible to every investor with access to the benchmark data.

The other number that matters: in 2025, 50% of GRESB development participants reported measuring embodied carbon. That is up from 31% in 2024 and 24% in 2023.

The market is moving, but it also means the other half, projects currently under development and investment decisions being made today, have no documented lifecycle data.

Those are the projects most exposed to a score penalty starting now.

The underlying logic of the change is straightforward. Operational emissions from buildings have been tracked and scored for years.

The assumption was that this was where most of the impact was. That assumption only holds for older, energy-inefficient buildings. For high-performance buildings, embodied carbon can represent 45-50% of total lifecycle emissions. In some cases, it exceeds 90%. Scoring only operational energy was leaving half the problem unmeasured.

Looking further ahead: from 2027, reporting shifts from portfolio level to individual asset level for upfront carbon emissions. A developer will need to document the carbon footprint of each project separately, not aggregate across a portfolio. The data infrastructure required to do that takes more than one reporting cycle to build.

For architects, engineers, and developers working on projects today: lifecycle assessments and Environmental Product Declarations are no longer tools for certification point-chasing. They are the documentation layer that determines whether a project can be financed on competitive terms in the next investment cycle.

2023 Embodied carbon introduced as an experimental, unscored indicator. 24% of developers report measuring it.

2024 Criteria developed. Still unscored. Adoption reaches 31%.

2025 Full reporting framework in place. Unscored, but evidence upload required. Adoption reaches 50%.

2026 Embodied carbon is scored for the first time. New 5-point indicator in the Development Component. Evidence required.

2027 Reporting shifts from portfolio level to individual asset level. Full project-vy-project documentation required.

Without a logical sequence, learning becomes content consumption. You accumulate information that doesn’t change how you decide.

UGREEN Pass organizes that into structured learning tracks: you choose your area, set your focus, and access the right courses for your goal.

A professional working to improve thermal performance takes a different path than one who needs to understand green building certifications. Each track follows a specific sequence, from foundational to advanced, without skipping the steps that actually matter in practice.

The event at the FIEP Convention Center gathered construction professionals for an afternoon of live simulations, green building certifications, and a discussion on Brazil’s new sustainable finance framework.

On May 15, the FIEP Convention Center in Curitiba hosted the first edition of Green Building Day XP, a format created by UGREEN to bring GBD content into a smaller, denser setting, with less distance between speakers and participants.

Architects, engineers, designers, and representatives from the construction sector attended. The program was structured in two content blocks with a networking break in between.

A large part of the audience stayed well past the official 6:30 PM closing time, with conversations continuing until 9 PM.

The first block opened directly: why do Brazilian buildings keep repeating the same performance failures?

Filipe Boni and Sami Meira led the discussion using concrete data, showing that excessive heat, high energy bills, and thermal discomfort are not coincidences. They are the result of design decisions made without bioclimatic criteria.

From there, each table received a challenge: develop strategies to improve building performance across three distinct climate contexts - Manaus, Brasília, and Curitiba (cities with different climates across Brazil).

While each group worked through the exercise, Filipe Boni ran live computational simulations, showing in real time how the strategies being discussed behave in practice.

The room generated genuine technical exchange: questions, debate, and detailed conversations about each scenario.

Ana Julia Kfouri opened the second block with an overview of the main green building certifications: LEED, EDGE, AQUA-HQE, WELL, and others. Beyond explaining the requirements, the discussion centered on a pointed question: when does certification actually make sense, and when does it not?

A real UGREEN consulting case followed to ground the argument in practice.

In a public school in Gravataí, southern Brazil, design decisions reduced annual energy consumption from 455 MWh to 279 MWh, a 38.7% drop. With a 38 kWp photovoltaic system added, the total reduction reached 51%, contributing 21 LEED points.

Sami Meira closed the technical content with Brazil’s Sustainable Taxonomy.

Established by Decree 12.705/2025, it defines what qualifies as a sustainable investment in Brazil and ties that classification to access to green credit lines starting in 2027.

Developers and companies that cannot prove performance with auditable data will face higher financing costs or lose access to those credit lines altogether.

To show that this path already has real practitioners, UGREEN presented the work done with Roca Brasil Cerâmica. By replacing petroleum coke with biomass and managing ESG KPIs on a continuous basis, the company closed 2024 with an emissions intensity of 4.55 kgCO₂e/m², below both the Italian average (5.0) and the Spanish (5.5), with a 33% reduction in emissions intensity since 2020 and 10,531 tCO₂ avoided over the period.

Rain Bird, Breton, and Mão Colorida sponsored the GBDXP.

All three brands presented on stage during the first block and maintained active exhibition stands throughout the event, with team members available for direct conversation.

A smaller, more interactive format with less distance between stage and audience - that was the premise of the Green Building Day XP from the start.

In post-event feedback, participants described the content as “instructive and accessible” and pointed to the approachability of the speakers as a highlight: “great networking, especially because the presenters were so easy to talk to.”

Curitiba was the first city. We are already evaluating the possibility of taking the XP format to other locations in Brazil.

Some projects start with solar panels, engineered wood, and a rainwater system. By the time construction begins, the wood is concrete, ventilation has been cut to code minimums, and the water system is off the scope. The explanation is always cost or supply chain risk.

Solutions exist for this problem, they have already been tested and carry performance data. What blocks them is how the sector decides, approves, and procures.

A longer approval process means idle capital, resulting in a compressed return, and when developers run that calculation, the sustainable solution disappears from the spreadsheet before it ever reaches the site.

What could function as a decision criterion gets reduced to a cuttable budget line. Understanding why that happens is the first step to changing it.
