The CTC Decarbonization Playbook
This is an operational starting point — a practical sequence from first data aggregation to first pour. Each phase systematically creates the conditions for the next.
Understand the Market
Before you can organize demand, you need to understand it
Map the concrete ecosystem in your region. How much concrete is being used? Where is it going? Who is placing it — public agencies or private developers? What strength grades are being specified? Where does the cement and aggregate come from, and what does it cost? This is the foundation everything else builds on.
- Demand volume and emissions profile
- Public vs. private sector breakdown
Organize Demand
Aggregating institutional demand with a data-backed RFI
With the data in hand, the next question is: who cares? Issue a Request for Interest (RFI) to public agencies and private developers. You will be surprised — many are already looking for a way to act. They just need someone to organize the effort. The RFI itself is an education tool — include your regional data and an emissions forecast so respondents understand the opportunity while expressing interest.
- Public agency commitments secured
- Private developer interest list built
Map Supply
Theory meets the plant floor
With organized demand and a coalition in place, producers pay attention. Issue an RFI to cement and ready-mix companies. Learn what they can actually make today, what it costs, and what they would need to scale. This is where theory meets the plant floor.
- Producer capability matrix completed
- Available SCM inventory mapped
Test & Qualify
Trust, and verify
Promises are not enough — the materials have to perform. Run pooled testing campaigns on candidate mixes across application families. When the test data comes back positive, skeptics become believers. This is the phase that turns "maybe" into "approved."
- Qualification test results documented
- Performance-based acceptance data collected
Rank the Pathways
If everyone does a little bit, the cost and risk are low
With tested materials in hand, run the cost-vs-carbon analysis. Factor in logistics — a cement substitute shipped 500 miles may not beat a slightly higher-carbon local mix on total emissions. The most economically efficient ton abated is the one to pursue first. Show this math to stakeholders: when everyone contributes a little, no one bears an unreasonable burden.
- Cost-vs-carbon ranking curves (MAC curve)
- Technology cost comparisons completed
Lock In the Framework
Remove the last barriers to scale
The pathway is clear, the materials are proven, the projects are ranked. Now design the policy and financing instruments that make it irresistible: Buy Clean specs, carbon budgets, green bonds, carbon credits. Public policy and private capital are complementary levers — use both.
- Policy recommendation package drafted
- Financing instrument design completed
Execute & Scale
Underwrite · Fix · Finance · Repeat
Everything has led here. Prep the supply chain. Train the ready-mix operators, concrete finishers, and inspectors on the new mixes. Run the pilot pours. Document the field performance. Then go project by project — Underwrite, Fix, Finance, Repeat. When the first slab cures at 30% lower carbon, the market shifts from theory to reality. Use the Concrete Atlas to show progress, celebrate the wins, and build momentum.
- Workforce training programs delivered
- Pilot pour documentation complete
This is a system, not a one-time project
As-poured data from Phase 7 feeds back into Phase 1, improving demand models and validating techno-economic assumptions. Each cycle sharpens the intelligence, lowers costs, and expands the market.
A coalition built to execute
No single organization can decarbonize concrete alone. The supply chain is a relay race — the city sets the rules, architects shape the demand, engineers approve the materials, contractors pour them, producers make them, and labs prove they work. Here's the role each player takes in the transition.
City Agencies
They set the rules of the game
- Set carbon targets for each concrete use case
- Require carbon disclosure in procurement bids
- Fund shared material testing
- Guarantee purchase of qualifying low-carbon concrete
% of city concrete under carbon rules
Architects
They decide how much concrete gets used in the first place
- Reduce unnecessary concrete volume in designs
- Simplify structural layouts
- Specify performance outcomes instead of recipes
- Identify projects ready for immediate adoption
Concrete volume avoided + carbon reduction
Structural Engineers
They hold the keys to what's "approved"
- Approve materials based on performance, not habit
- Reduce over-specified cement content
- Determine the minimum cement needed for each use case
- Define acceptable durability ranges
Lowest-cement pathway approved per project
Contractors
They're the ones who actually pour it
- Separate high-performance vs standard pours
- Document field performance of new mixes
- Offer lower-carbon alternatives in bids
- Share placement data with testing coalitions
Successful low-carbon placements
Ready-Mix Producers
They control what goes in the truck
- Develop carbon-disclosed product lines
- Provide pricing by carbon performance tier
- Participate in pooled testing campaigns
- Optimize mixes to hit carbon targets
Delivered cost at each carbon tier
Testing Labs
They provide the proof that makes everyone else comfortable
- Run standardized testing protocols
- Publish shared results for all coalition members
- Maintain clear approval criteria for new materials
Approved low-carbon pathways per campaign
Tracking systemic progress
Systemic change requires a scoreboard. These four categories tell you whether the program is actually moving tons — and whether the cost of doing so is going down each year, as it should.
Demand & Carbon
- Total cubic yards procured
- Weighted average GWP
- Emissions avoided vs baseline
- % of volume under threshold
Market Formation
- Number of compliant suppliers
- Price spread: incumbent vs low-carbon
- Volume clearing without support
- Volume requiring backstop
Qualification
- Pooled test campaigns completed
- Approved low-carbon pathways
- Cost per ton from qualification
- Applications with approved mixes
Finance
- Support dollars committed
- Support dollars actually spent
- Private capital unlocked
- Declining support over time

How CTC data powers each playbook module
No other platform has both supply-side intelligence and demand-side analytics
Most city playbooks assume you'll build the data infrastructure from scratch. CTC delivers the plant map, pricing engine, EPD benchmarks, and demand models on day one — so your team focuses on procurement reform, not data collection.
