Making Energy Cleaner and Models Smarter
IonQ is helping make energy cleaner using quantum computers. In 2025, IonQ’s technology made power grid simulations up to 50 times faster than before. This helps cities use wind and solar power without losing energy. When energy managers used IonQ’s computers, they found ways to reduce pollution by as much as 15%.
IonQ is also working with scientists to design better batteries and materials that can capture pollution out of the air. Their computers solved problems that regular computers could not, making new discoveries up to 70% quicker. That means new green tech, like battery storage and pollution capture, could become available sooner and help fight climate change.
By speeding up climate models and helping companies plan their energy use, IonQ is playing a big role in lowering emissions and helping the world become greener.
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.

Climate-Linked Supply Chain Risk Is Already in Your P&L
The earnings calls that quietly reframed climate from sustainability question to operating risk.
Three earnings calls in the last 18 months tell the story without any help from a press release.
Hershey, May 2024: cocoa price exposure compresses margin, and the company attributes part of the cost shock to West African weather. Olam, July 2024: coffee climate exposure quantified in the annual report. JBS, January 2025: supply chain climate disclosures expanded materially in response to investor pressure and regulatory expectation. None of these companies issued the announcement as climate news. They issued it as financial news. The climate-linked supply chain risk did not arrive with a sustainability framing; it arrived as a P&L line.
You are probably reading this article because you suspect the same thing is happening to your business. This piece walks through what is showing up on which earnings calls, how procurement and finance leaders are quantifying the exposure, and what serious corporates are doing about it before the regulator asks.
Where climate risk has already appeared in earnings
The pattern is consistent across resource-intensive sectors. A weather event compresses supply, the price spikes, the cost flows through the income statement, and the analyst on the call asks whether the event is anomalous or structural. Increasingly, the honest answer is the second one.
Cocoa is the cleanest example. The 2023 to 2024 West African harvest fell sharply on the back of erratic rainfall and disease. Cocoa futures more than tripled. Companies with concentrated West African sourcing absorbed the cost; companies with diversified sourcing absorbed less. The exposure was not climate as ESG topic. It was climate as cost of goods.
Coffee follows the same pattern. Brazilian and Vietnamese harvests have moved on weather more sharply across the last several seasons. Roasters with long-tenor supplier relationships and origin diversification have managed the volatility; roasters with spot-market exposure have not. Wheat, sugar, palm oil, beef: the same dynamic in different commodities, a pattern the IPCC AR6 Working Group II report projects will intensify across agricultural systems through mid-century.
What this means: climate risk is no longer a footnote in the 10-K. It is a line item the CFO has to explain on the call.
The three commodity exposures that hit margin first
For most companies with material Scope 3 exposure, three exposures dominate the near-term P&L risk.
- Concentrated single-origin sourcing in a climate-vulnerable region. If your tier-one supply for any material commodity sits in one geography, you have a concentration risk that climate amplifies. Diversification across origins is the obvious hedge, but it takes years to build and requires relationships you cannot acquire by tender.
- Supplier financial fragility under climate stress. Smallholder farmers, who supply a large share of the global cocoa, coffee, and palm oil market, do not carry the balance sheets to absorb yield shocks. When yields collapse, they exit. When they exit, your supply base shrinks, and the surviving suppliers raise prices. The risk is structural, not cyclical.
- Logistics and storage exposure to extreme weather. Hurricane disruptions to Gulf shipping, drought-driven Panama Canal restrictions, flooding in European inland waterways: each of these has moved input costs in the last three years, a pattern documented in Munich Re’s natural catastrophe data. The exposure shows up as a one-quarter event in the financial press but accumulates over time on the cost line.
TCFD and ISSB disclosure changes
The disclosure architecture has now caught up with the risk. The Task Force on Climate-related Financial Disclosures, whose recommendations are now embedded in the ISSB’s IFRS S2 climate standard, requires companies to disclose climate-related risks across physical and transition categories, with quantification where possible.
For physical risk specifically (the climate-linked supply chain risk you are reading about), the disclosure must address both acute exposures (extreme weather events) and chronic exposures (gradual changes in temperature, precipitation, and growing seasons). The disclosure must address the time horizon over which the risk is material, the parts of the value chain exposed, and the financial impact under different scenarios.
The CSRD imposes similar requirements under European law, with double materiality (both financial and impact materiality) embedded in the assessment. The practical effect: your auditors and your investor relations team now need a defensible answer to the climate-linked supply chain risk question, and the answer needs to be quantified.
What procurement and finance can do now
Three actions matter near-term.
Map your exposure. Most companies do not have a clear view of which tier-one and tier-two suppliers sit in which climate-vulnerable geographies. Without the map, you cannot quantify the risk, and without the quantification, you cannot disclose it credibly. The map is the foundation, and World Resources Institute climate risk research provides useful public tooling to start.
Diversify and deepen, in that order. Diversification across origins reduces concentration risk, but the deeper move is to invest in the resilience of the suppliers you already have. Regenerative practices, agroforestry, soil health interventions: these reduce yield volatility under climate stress and protect your input cost trajectory.
Embed the climate spend inside procurement, not outside it. Treating climate risk as a sustainability cost line subordinates it to the ESG budget. Treating it as a procurement and resilience investment puts it in the budget that matters, which is the cost-of-goods budget that the CFO defends quarterly.
Nature-based supply chain investments are the asset class designed for exactly this purpose. They sit inside the value chain, they reduce climate-linked supply risk, they generate verifiable Scope 3 reductions, and they produce the documentation an auditor and a regulator can both test.
If you are quantifying climate-linked supply chain risk in advance of the next earnings cycle or the next disclosure period, the carbon and sustainability experts at Carbon Credit Capital can help you map your exposure and structure a Dual-Value Model response that addresses reduction, resilience, and disclosure-readiness in a single program.

Carbon Footprint
Where should an SME start with a carbon action plan?
More and more small and medium-sized businesses are hearing the same question from their larger customers: What is your carbon footprint? That question now travels down entire supply chains, and it arrives next to tender requirements, certification criteria, and rising customer expectations.

Insetting vs Offsetting: Which Actually Counts Toward Your Scope 3 Targets
The accounting differences that decide whether your nature investment shows up in inventory, in BVCM, or nowhere at all.
The question reaches a procurement team about three weeks before the next sustainability committee meeting. Someone has read about insetting. Someone else has just signed off on an offset purchase. The CSO wants to know if the two are interchangeable. The answer is no, and the GHG Protocol Land Sector and Removals Standard is the reason why.
This article walks through what each term means at audit-grade specificity, what the standards actually say about how each gets counted, and how to decide which tool fits which target. The insetting vs offsetting question is one of the most-searched in corporate climate strategy, and one of the most poorly answered. By the end of this piece, you should be able to brief a committee on the difference without notes.
The two definitions, in plain English
Offsetting means buying carbon credits generated outside your value chain and retiring them against your residual emissions. The reduction happens somewhere else, financed by you, and the credit is the receipt.
Insetting means investing in emission reductions or removals inside your own value chain, typically with suppliers, where the reduction is directly linked to the products and services you buy. The reduction happens inside the boundary of your Scope 3 inventory, and the accounting treatment is fundamentally different.
The shorthand from the University of Oxford’s Nature-based Insetting Initiative is useful: insetting is what you do with the supply chain you have; offsetting is what you do with the supply chain you do not have.
What the GHG Protocol Land Sector Standard actually says
The GHG Protocol Land Sector and Removals Standard, finalised in 2024 after a multi-year pilot, sets the rules for how land-based emission reductions and removals enter corporate inventories. The Standard distinguishes between inventory accounting (Scope 1, 2, and 3) and project or intervention accounting (a separate methodology for crediting).
For insetting, the practical implication is that supplier-level interventions, when properly measured and attributed, can reduce your Scope 3 category 1 (purchased goods and services) emissions in your inventory. The reduction is not a credit retired against the inventory; it is a lower inventory number, period.
For offsetting, the credit is retired separately. It can be reported as a contribution toward a net-zero claim under the SBTi Beyond Value Chain Mitigation framework or as part of a VCMI Carbon Integrity claim, but it does not lower the inventory number.
A practical consequence: if your Science Based Target requires a 50% absolute reduction in Scope 3 emissions by 2030, insetting moves you toward the target. Offsetting does not. This single point of difference reshapes the procurement decision.
When insetting counts toward Scope 3 (and when it does not)
Insetting counts toward Scope 3 only when several conditions are met:
- The intervention must occur with an entity in your value chain.
- The emissions reduction or removal must be measured against a defensible baseline.
- The reduction must be attributed to your share of that supplier’s output, not double-counted with other buyers.
- It must follow the inventory accounting rules in the GHG Protocol Land Sector Standard, not the project accounting rules used to generate credits.
The most common failure mode is double counting. If your supplier sells the same reduction as a credit on the voluntary market and also reports it to you as a Scope 3 reduction, the math breaks. The Standard requires you to address this risk, typically by purchasing and retiring the supplier-issued credit as part of your inventory or by contractual provisions that prevent the supplier from selling the reduction twice.
When insetting does not count toward Scope 3: when the intervention sits with a supplier you do not buy from, when the baseline is not defensible, when the attribution is unclear, or when the documentation does not survive audit. Those cases default to Beyond Value Chain Mitigation, which is still useful but operates on a different ledger.
The procurement and supplier engagement question
Insetting is harder than offsetting. That is the unfashionable truth most buyers eventually confront. Offsetting is a transaction; insetting is a relationship.
To run an insetting program, you need supplier mapping precise enough to know which farms or facilities sit at which Scope 3 boundary. You need an engagement model that gets suppliers to participate, which usually requires multi-year commitments and shared economics. You need an MRV architecture that measures the right things and produces audit-ready documentation. And you need a contractual structure that prevents double counting and protects both sides.
The trade-off you receive in return is significant. Reductions count against your inventory rather than your residual. Supplier relationships deepen, which protects sourcing continuity. Yield and quality improvements often follow regenerative interventions, which reduces your input cost over time. And the regulatory file, under CSRD, CSDDD, EUDR, and the SBTi FLAG Guidance, is materially stronger.
Choosing the right tool for the right target
A practical decision rule. If your target is a science-based Scope 3 reduction and you operate in a FLAG sector or source FLAG commodities, insetting is the structurally correct tool. If your target is a net-zero claim that includes neutralising hard-to-abate residual emissions outside your value chain, BVCM via high-integrity offsets is the structurally correct tool. Most companies with material Scope 3 exposure need both, in different proportions, sequenced over time.
The sequencing matters. Insetting takes longer to stand up but produces a permanent reduction in the inventory. Offsetting can be transacted faster but does not change the inventory and now sits under tighter claim restrictions. Treat them as complementary tools with different jobs, not as substitutes. The Accountability Framework Initiative and the IUCN Global Standard for Nature-based Solutions both provide useful guardrails for the insetting side, with biodiversity, human rights, and benefit-sharing requirements that go beyond carbon math.
If you are mapping a Scope 3 reduction roadmap and need to scope which interventions count toward your inventory versus which sit in Beyond Value Chain Mitigation, the carbon and sustainability experts at Carbon Credit Capital can help you structure a nature-based supply chain investment program that fits your FLAG exposure, your target architecture, and your audit horizon.
