2. D-Wave (QBTS) Poised for Growth with Quantum Advantage
D-Wave (NYSE: QBTS) is charting its own path. Rather than developing general-purpose quantum computers, it specializes in quantum annealing. This method excels in optimization tasks like logistics and statistical modeling. This focused strategy helps D-Wave capture valuable use cases without trying to cover the whole quantum market.
Notably, it stands out as the only company offering both annealing and gate-model systems. Over 100 clients, including government and enterprise customers, are using its solutions.
Additionally, the company announced in March that Ford Otosan has used D-Wave’s technology to improve production sequencing for its Ford Transit line.
Revenue and Cash Boost
The company reported a record Q1 fiscal 2025 revenue of $15 million. This is a 509% increase from $2.5 million last year. Its cash balance climbed to $304.3 million, bolstered by $146.2 million raised through its ATM program.
Advantage2 Expands Commercial Reach
D-Wave launched its sixth-generation Advantage2 system. It has over 4,400 qubits, making it the most powerful quantum computer they’ve created so far. This system addresses real-world issues that classical computers struggle with. Commercial adoption is accelerating, with bookings in APAC rising 83% in 2025.
Investor Outlook
Wall Street is optimistic. We also see that Piper Sandler raised its target to $22, Stifel set a $26 target, and Benchmark maintained its $20 Buy rating. Strong demand, solid funding, and growing commercial applications make QBTS a leader in the quantum field. Most significantly, analysts see the revenue jump as a solid path to profitability.
Quantum Solutions for Cleaner Cities
D-Wave’s technology and quantum computers help save energy and cut down pollution. D-Wave worked with a utility company in Europe to manage solar and wind power, making those clean energy sources more reliable and efficient. Their computers help balance the flow of energy so that less is wasted, meaning fewer fossil fuels are needed.
In Tokyo, D-Wave helped set up smart trash collection. Their computers figured out how trucks could use shorter routes and fewer vehicles. This cut down driving by 57% and saved a lot of fuel. In other tests, D-Wave’s technology helped reduce traffic jams by 17% and cut emissions in supply chains by 20%.
D-Wave’s newest computers use much less energy than big data centers. Their systems let companies manage energy and deliveries in ways that were never possible before, helping cities get cleaner and businesses save money.
3. Quantum Computing Inc. (QUBT): A High-Risk, High-Reward Quantum Play
Quantum Computing Inc. (Nasdaq: QUBT) focuses on photonic chip integration. It also launches Quantum AI and cybersecurity products. Currently, its early revenues are low. The company relies on government and industry partnerships. This dependence brings execution and adoption risks.
The company recently disclosed that it has $850 million cash position, strengthened by a $500 million private placement in September 2025. These funds support fab scaling, hiring, strategic acquisitions, and commercialization efforts.
Some commendable product developments include delivering a quantum photonic vibrometer to Delft University of Technology. It also shipped its first entangled photon source to a lab in South Korea. Meanwhile, a top-five U.S. bank adopted the Quantum Cybersecurity Solution. These wins show that QUBT’s products solve real-world challenges.
Foundry Powers Scale and Performance
The company’s thin-film lithium niobate (TFLN) foundry in Tempe, AZ, is now fully operational. It integrates nano-photonic chips into quantum systems. This improves size, weight, power, cost, and performance. External services also boost revenue in datacom, telecom, sensing, and quantum computing.
However, QUBT faces strong competition from IonQ and D-Wave. High risks in execution and adoption make this suitable for risk-tolerant investors. They seek asymmetric upside in early-stage quantum photonics.
Tracking Pollution and Saving Energy
QUBT builds quantum computers that help track pollution and save energy every day. Their machines are easier and cheaper to run than the biggest supercomputers. In 2024, QUBT invested millions to help forecast climate changes and make electric grids better. Their computers measure carbon pollution in the air almost twice as accurately as older methods, which means cities and governments can know what’s happening and act faster.
By working with power companies, QUBT found ways to cut energy waste by 37%. They believe their technology will help make big improvements – up to 52% – in just a few years. QUBT computers are also making it easier for countries and companies to test how well climate laws work and fix problems quickly.
With better data and faster answers, QUBT is helping people support a cleaner future through smarter science and technology.
4. Rigetti Computing (RGTI): The Future of Quantum Hardware
Rigetti Computing (NASDAQ: RGTI) is a top quantum computing stock drawing strong investor interest. The company is pushing forward with superconducting qubit technology and bold innovations. However, its revenue is small compared to its high valuation.
Leading in Quantum Hardware
Rigetti employs a chiplet-based approach to scale its quantum processors, distinguishing it from IBM and Google. Its Cepheus™-1-36Q system is live on Rigetti’s Quantum Cloud Services and will soon be on Microsoft Azure.
In September 2025, the company launched a 36-qubit processor that cut two-qubit errors in half and achieved 99.5% gate fidelity. This progress shows it can scale to over 100 qubits.
Market Momentum and Funding
Revenue for Q2 2025 is $1.8 million, which is modest. Shares are trading around $32, up over 4,000% in the past year. Rigetti has about $571 million in cash and no debt. This provides a strong runway for research, partnerships, and production.
Key collaborations include Quanta Computer’s $35 million investment, contracts with the U.S. Air Force, and ties with India’s C-DAC for hybrid quantum systems.
Risks and Outlook
Most analysts rate RGTI stock a “Buy,” but its stock price exceeds many targets. The price-to-sales ratio is around 900x. This means Rigetti offers high-risk, high-reward exposure to next-generation quantum computing. It suits investors willing to bet on long-term breakthroughs and tolerate short-term volatility.
Building Better Batteries and Clean Tech
Rigetti is building quantum computers that help scientists create new batteries, solar panels, and even machines to capture pollution. Their computer chips work with very few mistakes, so testing new clean tech designs is quicker and cheaper. In 2025, Rigetti joined with governments and technology companies to set up projects using quantum computers in clean energy labs.
Rigetti’s computers helped make battery and solar designs three times as fast as before. A recent U.S. Air Force project spent $5.8 million to test Rigetti’s computers for national security and energy grid science. With international orders for their systems, Rigetti’s technology is helping researchers all over the world find the fastest ways to cut pollution and improve clean energy.
Rigetti is proving that new quantum computers can help jumpstart the next wave of green inventions.
Power Needs and Efficiency of Quantum Computing
Quantum computers demand significant energy to operate, especially superconducting qubit systems that must stay near absolute zero—about 0.015 Kelvin. And cooling consumes a significant 70% of the total power.
- A single quantum system can consume 220,000 to 438,000 kWh annually, similar to the energy use of 20 to 40 average homes.
As qubit numbers grow, larger systems may need hundreds of kilowatts continuously. Researchers are testing energy-efficient cooling methods and developing qubits that can work at higher temperatures, which could significantly lower energy demand.
However, even with these requirements, quantum computers still use far less electricity than traditional supercomputers. Companies are also adopting sustainability measures, using renewable energy, modular hardware designs, and recycling rare materials to reduce their carbon footprint.
Accelerating Clean Tech and Materials Innovation
Quantum computing is changing how we approach materials and clean energy. A McKinsey report highlighted the following:
- It is helping develop sustainable batteries, high-efficiency solar panels, and improved catalysts for carbon capture.
- Researchers are creating battery chemistries that rely less on lithium and cobalt and designing solar materials that are safer and more effective.
- Quantum simulations can also uncover compounds that make CO₂ capture and storage cheaper and more energy-efficient.
- In energy systems, quantum machine learning and annealing help forecast supply and demand, optimize production, and integrate renewables into the grid.
These advances boost reliability, cut emissions, and make clean energy solutions more affordable, moving the world closer to sustainability goals.
As these companies advance their technology and scale operations, these pure-play quantum stocks may unlock massive growth. This makes it one of the most exciting sectors to watch.
Quantum computing is more than just a high-tech idea – it’s becoming a real-world tool for solving tough climate problems. Companies like IonQ, D-Wave, QUBT, and Rigetti are leading the way. Their computers let us model and fix energy systems, track pollution, and invent new green technologies faster than ever. This means not just a smarter future – but a cleaner, healthier planet for everyone.

Insetting program design starts with your supplier map. The carbon claim comes much later.
Consider a coffee procurement team that funds a farm intervention before checking its sourcing data. The supplier aggregates coffee lots from several regions. The buyer lacks farm-level traceability. Another purchaser expects to report the same outcome. A more attractive project brochure solves none of these problems.
If the distinction between a value-chain intervention and a purchased credit is still open, read CCC’s Insetting vs Offsetting guide before you set the brief.
Insetting program design begins with the purchasing relationship and works outward. You need to decide 1) where an intervention belongs, 2) what business problem it addresses, 3) who pays for it, 4) how results will be measured, and 5) what the evidence will let you say about them. This five-step playbook turns that sequence into a procurement plan.
Step 1: Insetting program design starts with supplier mapping
Start with the commodities that matter most to your Scope 3 inventory and sourcing continuity. Ask finance for spend by supplier, sustainability for the emissions baseline, and category managers for origin and volume records. Then identify which suppliers can trace material to a jurisdiction, sourcing region, producer group, or individual land-management unit.
The level of traceability affects what you can account for. Under the GHG Protocol Land Sector and Removals Standard, the spatial boundary for purchased land-based products depends on the traceability associated with each volume. Farm-specific factors or removals require physical traceability through an acceptable chain-of-custody model. A contract with a tier-one trader, by itself, does not establish a link to the farms behind its deliveries.[1]
Build a first-pass table with five columns: commodity and annual volume; supplier and origin; current traceability level; land-use and production risks; and the business owner who can change the purchasing terms. Mark missing data plainly. A blank cell is cheaper to fix before a program starts than after a claim is drafted.
If your company sets an SBTi Forest, Land and Agriculture target (FLAG), keep its land-related target boundary separate from energy and industry emissions. The current FLAG guidance also requires relevant companies to assess primary deforestation-linked commodities in their value chains.[2]
Step 2: Choose a commodity and jurisdiction for a pilot
Select one supply corridor where the sourcing connection can be established and procurement has a reason to stay. A useful pilot has repeat purchases, suppliers willing to share records, an intervention matched to a diagnosed problem, and a defined plan to measure the result. Carbon potential alone is a poor selection rule if the supplier cannot deliver the crop your business needs.
Compare candidate regions on land-use risk, supplier concentration, local rights and tenure, the availability of baseline data, and exposure to drought, erosion, or forest conversion. Check the relevant legal requirements separately. A nature project does not satisfy a due-diligence obligation merely because it has a carbon method attached.
Consider a coffee buyer sourcing from two districts. In the first, producer-group records identify the farms, while recent dry seasons have increased rejected green coffee lots. In the second, deliveries pass through several intermediaries and farm origins are unknown. Pilot shade management in the first district, with local agronomic advice and quality checks built into the plan. The buyer can trace purchases there and test the intervention against a defined sourcing problem.
Use a short decision memo to record why the selected corridor beats the alternatives, what remains uncertain, and what would stop the pilot. That memo is the first control against a project drifting toward whatever happens to photograph well.
Step 3: Design the supplier engagement and commercial model
The intervention needs an owner on each side of the contract. Decide who supplies planting material or training, who maintains the practice, who bears the cost if a harvest disappoints, and how long the buyer expects to purchase from participating suppliers. Where smallholders participate, budget cash flow and technical support for practices that offer a later return.
Put these terms in a supplier agreement or pilot addendum. It should cover eligible farms and volumes, consent to data collection, access for monitoring, any land or carbon rights that matter, benefit sharing, and what happens if the purchasing relationship ends. Ask local counsel and producer representatives to review the arrangement. The Accountability Framework is a useful reference for supply-chain work involving forests, ecosystems, and human rights.[3]
Avoid assigning an automatic carbon benefit to the buyer. The contract should say which party has the right to report each outcome, how overlapping claims will be checked, and how any issued credits will be handled. A reduction reported in a buyer’s inventory cannot simply be sold for someone else’s offset claim without an accounting review. SBTi FLAG guidance excludes purchased credits used as offsets from near-term FLAG target achievement.[2]
Set commercial measures beside environmental ones: delivered volume, rejection rate, supplier retention, and procurement cost. They tell you whether the program works as a supply-chain investment, even if carbon accounting takes longer to resolve.
Step 4: Build monitoring, reporting, and verification before rollout
Agree on the baseline and data flow before paying for a full rollout. Identify the land units or sourcing regions in scope, the practices that change, the records suppliers already keep, and the additional measurements the program requires. Decide which data can come from field visits, transaction records, or remote sensing, and who checks each source.
For carbon, separate three questions. Did the practice happen? Did emissions or removals change under an applicable method? Can the buyer attribute a defensible share to its purchased goods without double counting? The GHG Protocol’s 2026 guidance includes dedicated chapters on spatial boundaries, data and methods, evaluating actions, credited outcomes, and assurance.[1] These are distinct jobs. A photograph of a planted tree answers only part of the first.
CCC’s MRV and Additionality article explains the separate evidence questions a project reviewer will ask.
Create an evidence file for every reporting period: dated supplier and farm records, purchase volumes, methods and emission factors, uncertainty, quality checks, and changes from the baseline. Specify who can challenge the data and how corrections are recorded. If a project also seeks credit certification, keep project accounting and corporate inventory accounting separate. The GHG Protocol says its land standard focuses on entity-level inventories and does not set the rules for credit certification.[4]
Start with the minimum viable measurement design that can survive review. Add complexity when the pilot tells you which data actually changes a decision.
Step 5: Decide what can be reported and claimed
Insetting program design needs reporting rules before the marketing copy. Procurement, sustainability, finance, and legal should agree on four distinct outputs: operational performance; observed land or nature outcomes; inventory effects, if the accounting criteria are met; and any separately issued credits. One dashboard can display them, but they should not share a single unqualified headline.
SBTi FLAG guidance allows certain land-based removals within a company’s operations or supply chain to contribute to FLAG pathways, subject to criteria including permanence, traceability, data quality, and allocation. It does not allow purchased offsets to meet near-term FLAG targets.[2] Eligibility therefore depends on evidence and the applicable target rules, not on calling an activity “insetting.”
Draft a claims register. For each proposed sentence, record the period, boundary, data owner, calculation method, reviewer, and whether the result is measured, estimated, or still a goal. If the evidence supports only “we funded a pilot with 200 farms,” say that. Do not turn a funding fact into a verified emissions reduction.
What good looks like by year three
Treat year three as a review point, not a promised payback date. A mature pilot should have mapped participating supply volumes, a stable supplier agreement, a repeatable data collection process, and a comparison of commercial and environmental results against the baseline. It should also have a documented answer for outcomes that cannot be included in the buyer’s inventory.
Scale only where the pilot improves a sourcing decision and the evidence can follow the product. If neither condition holds, redesign the intervention or change the corridor. A disciplined program can conclude that a site is unsuitable. That is useful procurement intelligence.

Nature-based carbon investments deserve consideration when they address a specific business dependency and produce outcomes you can measure. Imagine Moonbucks, a global coffee roaster planning next season’s espresso blend. It is considering natural Grade 4 coffee from Jimma, in southwestern Oromia, Ethiopia. Its sourcing decisions affect the roasting schedule and the cash tied up in coffee purchases. Moonbucks needs to understand which measures could protect that supply, what they would cost and how it would judge the results.
1. Define the sourcing problem before choosing a project
Moonbucks needs a dependable component for its espresso blend. Its procurement team wants continuity of volume and an agreed cup profile. Replacing a shipment at short notice could require new sample approval and changes to the blend, and given the schedules for cultivation, processing, and freight delivery, is practically impossible. Moonbucks needs to get this right, and its initial concern is inconsistent deliveries. It commissions an assessment of the supplying farms and post-harvest chain. The questions cover land condition, harvest availability and whether drying or storage problems are affecting saleable lots.
This distinction changes the investment brief. A tree-planting proposal cannot be assumed to fix drying problems. Better storage cannot restore eroded land. The team must establish which problem exists before selecting the response.
CCC’s guide to finding nature-based solutions in your supply chain explains where to look. Here, the next task is to turn a broad concern into a testable proposal.
2. Develop nature-based carbon investments around the actual supply chain
The assessment would trace Moonbucks’ purchases back through the exporter and supplying producer groups. Which farms supply the contracted lots? Who controls land-management decisions? How long does the buyer expect to maintain the purchasing relationship?
Furthermore, Jimma natural Grade 4 cannot be treated as interchangeable with every Ethiopian coffee. Moonbucks would need to test any substitute against its own blend and quality requirements.
Suppose Moonbucks’ assessment identifies an opportunity to maintain shade tr
