In 2019, Roca Brasil Cerâmica commissioned a full Life Cycle Assessment of its production. No other ceramic tile manufacturer in Brazil had done this before. The study mapped energy flows and emissions at each stage of the production line — from clay extraction to packaged product — and identified where the main problem was: the atomizer furnaces.

Atomizers convert wet clay into granulated powder, the raw material for porcelain tiles. It is one of the most energy-intensive steps in the factory. The fuel was petroleum coke. Based on the LCA findings, the company began replacing it with biomass pellets and briquettes derived from wood industry residues. The transition started in 2021. By 2022, all plants were running without petroleum coke.

In March 2025, these figures were presented by Sami Meira at the 3rd Federal MRV Technical Workshop in Brasília, during the regulatory process for Brazil's Emissions Trading System. The presentation included a proposal to the federal government: to recognize clay quarry restoration as a source of carbon credits under the Brazilian ETS.

The fuel switch was not a communications decision. It was a process engineering decision, driven by life cycle data. The LCA located the main emissions source — the atomizers — and made it possible to quantify the impact before any change was made. Without that mapping, the fuel replacement could have targeted the wrong stage, at insufficient scale, or not happened at all.

Four years later, the result is verifiable: emissions intensity of 4.55 kgCO₂e/m², below Italy and Spain, against a global average of 14.40 kgCO₂e/m². That places the domestic production of one specific manufacturer ahead of the main European benchmarks in the sector.

The regulatory context makes this more pressing than it appears. Brazil's Emissions Trading System is under active regulation. MRV criteria — monitoring, reporting, and verification — are being defined now, with input from industries that already have structured inventories. Manufacturers that haven't started this process will enter the regulatory environment without emissions history, without a baseline, and without the ability to demonstrate reduction.

Building that history takes time. Roca Brasil Cerâmica took four years to arrive at the numbers presented in Brasília. That is the timeline the market rarely accounts for until the requirement is already in force.

In 2023, climate disasters displaced 7.7 million people worldwide. Cities are warming roughly twice as fast as the global average. The construction industry’s primary response is still, in most cases, more concrete.

That model has a name: grey infrastructure. Retaining walls, drainage pipes, levees, and pumping systems. They worked for decades. Now they are reaching their limits. The cost shows up in buildings, in specifications, and in municipal budgets.

The response gaining global traction is blue-green infrastructure.

The concept connects two systems. Green covers urban forests, vegetated roofs, rain gardens, and permeable pavements. Blue includes lakes, re-naturalised streams, wetlands, and drainage networks. Together, they form an integrated environmental management network that operates from the building to the city scale.

At the project level, the term is blue-green architecture. It describes the integration of vegetation with rainwater and greywater management within the building itself.

A scientific review published in 2025 confirms: the urban heat island effect worsens flooding events. These are not two separate problems. They are the same problem with two faces. Grey infrastructure does not address either one efficiently.

The economic argument is direct. A single storm in Copenhagen in 2011 caused between DKK 5 and 6 billion in damage. The blue-green plan adopted afterwards cost DKK 13 billion. The grey alternative, with equivalent protection, came to DKK 20 billion. The nature-based solution was the cheaper option.

In practice, blue-green infrastructure is not a checklist item. It is a design decision. It starts with how a site handles rainwater. It extends into choices about roofing, paving, landscaping, and the site's relationship with surrounding water systems.

Rain gardens, retention-layer roofs, bioswales, and stormwater-detention parks are tools with measurable performance and calculable cost. The City of São Paulo incorporated these solutions into its official drainage and urban design guidelines. The technical parameters exist. The challenge is knowing how to apply them.

Long-term assessments are scarce. Adoption scale remains small. Connecting decentralised solutions is a real planning challenge. A well-designed rain garden does not fix a full watershed. A green roof does not replace an undersized drainage system.

What blue-green infrastructure does address are the problems that grey infrastructure can no longer handle alone: heat and water, at lower cost and with greater benefit for the people using the spaces.

Floor-to-ceiling glass, clean volumes, no overhangs or shading — a perfect picture. But at 2 p.m. in January, the room turns into a greenhouse. The air conditioning runs all day, and the client ends up paying a premium for a space that’s uncomfortable to use.

This isn’t an isolated case. It’s become a pattern, driven by a market that rewards image over performance.

Eye-catching designs can sell up to 15% faster. But studies show that actual energy consumption in buildings can reach up to five times the projected values — in some cases, even ten times. And that gap shows up directly in the utility bill.

When design decisions prioritize aesthetics without considering solar orientation, thermal loads, and user behavior, the building ends up working against the people inside it.

Overhangs removed to “clean up” the form. Glass selected for its color rather than its performance. Simulations based on ideal conditions, ignoring the real surroundings. Each of these choices carries costs that accumulate over decades.
