Is the Climate Tech Market growing now?
In our climate tech market deck, you will find everything you need to understand the market
SUMMARY
Yes, the climate tech market is growing now, but the growth is concentrated in the parts of the market that solve immediate economic, infrastructure, or operating problems.
The strongest signal is not sentiment but deployment. Global energy transition investment reached a record $2.3 trillion in 2025, EV sales crossed 20 million, and renewables added almost 700 GW of new capacity.
The market is no longer moving as one category. Grid equipment, utility-scale solar, electrified transport, carbon removal contracts, and power infrastructure are advancing, while U.S. residential solar, green hydrogen, and subsidy-sensitive manufacturing are much weaker.
Climate tech has shifted from a “green premium” market to a painkiller market. Buyers are spending when the product lowers energy costs, unlocks power capacity, reduces risk, improves resilience, or helps them comply with hard rules.
Venture funding has not disappeared, but it has become much less forgiving. Climate venture and growth investment reached $40.5 billion in 2025, yet capital is moving toward mature technologies, infrastructure-linked demand, and teams with execution records.
AI is changing the climate tech story in two directions at once. It diverts venture attention away from climate-only narratives, but it also creates huge demand for power, grid connections, cooling, storage, and cleaner firm electricity.
The grid looks like one of the clearest winners because it sits under almost every other transition market. Renewables, EVs, factories, AI data centers, and electrification all need the same constrained infrastructure.
The weakest categories share the same pattern: they need too many things to go right at once. Green hydrogen, battery factories, and some clean manufacturing projects depend on patient capital, stable subsidies, cheap energy, bankable buyers, and flawless execution.
Corporate climate budgets are not simply being cut. They are being renamed and moved from ESG teams toward finance, operations, infrastructure, risk, and energy procurement.
Carbon removal is becoming more real, but still not broad enough. Contracting volumes accelerated sharply in Q1 2026, yet the buyer base remains concentrated and delivery risk is still high.
The best read is that climate tech is maturing, not collapsing. Strong segments are becoming infrastructure markets, while weaker segments are being forced through bankruptcies, cancellations, consolidation, and stricter capital discipline.
So the answer is not “climate tech is back” or “climate tech is dead.” The market is growing where it has hard demand, and shrinking where it still relies on cheap capital, unstable policy, or buyers paying mainly to look green.

Why is climate tech so hard to read right now?
Because climate tech is expanding where it has direct economic pull. However, it is struggling where it still depends on cheap capital, generous subsidies, or buyers paying a green premium.
The bullish case is clear.
Global energy transition investment reached a record $2.3 trillion in 2025, up 8% from 2024. That is a huge spending base. It does not look like a small startup category. The biggest buckets were electrified transport, renewable energy, and grid investment. EV sales also crossed 20 million globally in 2025, and renewables added almost 700 GW of new capacity, mostly solar.
Those are hard deployment signals.
The company-level signals also show momentum in the parts of climate tech that touch power infrastructure. GE Vernova’s Q1 2026 orders rose 71% organically, and its electrification segment booked $2.4 billion of data-center-related equipment orders in one quarter, more than it booked in all of 2025. First Solar reported Q1 2026 net sales up 24% year over year and a contracted backlog of 47.9 GW.
That tells us customers are not just “interested” but actually ordering equipment years ahead.
But the bearish case is also real.
Energy-startup venture capital fell for the third straight year in 2025. U.S. clean energy manufacturing cancellations continued in Q1 2026, with $1.4 billion of cancelled investment and 8,100 jobs lost. Enphase’s U.S. revenue fell 23% quarter over quarter in Q1 2026, and U.S. sell-through dropped 48% after the residential solar tax credit expired. Northvolt’s 2025 collapse also showed that even “strategic” climate companies can break when factory execution, financing, and customer demand do not line up.

What do analysts say about climate tech growth?
Analysts still expect climate tech to grow fast, but we should treat those forecasts as directional evidence, nothing more.
The market research view is broadly positive.
Fortune Business Insights estimates the climate tech market at $31.45 billion in 2025 and $39.14 billion in 2026, then projects $209.48 billion by 2034. Grand View Research estimates $38.5 billion in 2024 and forecasts $115.4 billion by 2030. Research and Markets puts the 2026 market at $40.26 billion and projects $97.99 billion by 2030.
The direction is consistent: these firms think climate tech is still a growth market. But the exact numbers are less important than they look.
Some reports define climate tech like an enterprise software and services market. Others include carbon management, clean energy, sustainable mobility, environmental monitoring, climate intelligence, and industrial decarbonization. BloombergNEF’s $2.3 trillion energy transition investment number is much broader again because it includes transport electrification, renewables, grids, supply chains, and transition finance.
That is why we should not over-read the CAGR. A 20%+ forecast sounds clean, but it hides the messy part: some climate categories are accelerating, while others are shrinking or resetting. Analyst forecasts tell us the long-term demand pool is real.
They do not tell us whether founders are raising now, whether customers are buying now, or whether projects are getting built now.
So we use analyst forecasts as one layer. The real question is what the ground signals say. And this is what we’re looking at now.
As this chart shows, and as featured in our climate tech market deck, search interest in climate change has continued to rise
Are climate startups still raising, or did the money dry up?
Climate startups are still raising, but the market has become much pickier.
The headline funding signal is healthier than the mood. Sightline Climate reported $40.5 billion of climate venture and growth investment in 2025, up 8% from 2024. That is not what a dead category looks like. State of Climate Tech also described Q1 2026 funding as stable, but with tighter capital allocation and more “conviction-led deployment.” In plain English: investors are still writing checks, but fewer teams get the benefit of the doubt.
The dry powder signal says the same thing. Climate investors still had roughly $90 billion of dry powder in Q1 2026. That is a lot of capital waiting to be deployed. But it is down from a $112 billion peak in Q1 2025, and Sightline noted that the center of gravity has shifted toward infrastructure, mature technologies, and companies with real execution records.
The deal examples support that. Gigascale Capital launched a $250 million fund in June 2026 around rebuilding the physical economy. VoLo Earth closed a $135 million second fund. Varaha raised $45 million in early 2026 for agricultural carbon projects. These are bets on physical assets, measurable carbon outcomes, and infrastructure-linked demand.
So, it looks like the money is moving from broad enthusiasm to proof-heavy categories.
Did AI steal the climate tech venture story?
We believe AI did not kill climate tech, but it did make climate-only fundraising harder.
The IEA’s energy innovation work shows the pressure clearly. Venture capital into energy technology startups fell to $27 billion in 2025, its third straight annual decline. At the same time, AI’s share of global VC rose sharply, with AI taking almost 30% of global VC funding in 2025.
That is a big opportunity-cost signal. When the hottest category in venture absorbs more attention, slower hardware-heavy climate companies have to work harder.
But AI is also pulling capital back into energy through the side door. Data centers need power, grid connections, transformers, backup generation, cooling, storage, and cleaner firm power. GE Vernova’s Q1 2026 data-center equipment orders show this very directly. The company booked more than $2 billion in data-center-related electrification equipment in one quarter, more than all of last year.
That creates a strange market. A founder saying “we are a climate startup” may get less attention than in 2021. A founder saying “we solve power constraints for AI infrastructure” may get more. The technology can be the same. The budget line is different.

Are customers buying climate tech, or just making pledges?
Customers are buying when the product solves a hard operating problem. They are much less reliable when the product only helps them look greener.
The strongest customer signal is actual capital spending. Global energy transition investment reached $2.3 trillion in 2025. That is bigger than the GDP of many major economies. It included $893 billion for electrified transport, $690 billion for renewable energy, and $483 billion for grid investment.
It shows the buyer is no longer only a sustainability team. It is utilities, automakers, fleet operators, grid operators, manufacturers, data-center developers, and infrastructure owners.
Corporate demand is also showing up in carbon removal, though in a narrower way. Durable carbon removal contracts hit record Q1 levels in 2026. CDR.fyi reported 2.3 million tonnes contracted in Q1 2026, roughly 5.6x Q1 2025. ClimeFi reported a similar acceleration, with Q1 2026 durable CDR contracts more than doubling year over year. That is customer demand, not just startup supply.
But the weak signal is important too. Green hydrogen still has trouble turning announcements into bankable offtake. Residential solar demand in the U.S. fell sharply after incentives changed. Some clean manufacturing projects were cancelled when policy and economics got worse. That tells us customers are not buying “climate” in the abstract.
So, climate tech demand is growing where the buyer already has a painful budget problem.
Is the grid the real climate tech winner right now?
The grid looks like one of the strongest climate tech markets right now.
This is not because the grid suddenly became fashionable but because everything else is hitting the same bottleneck: renewables need interconnection, EVs need charging, factories need electrification, AI needs power, and utilities need reliability. When one bottleneck blocks many markets, money flows toward it.
GE Vernova is the clearest public-company signal. In Q1 2026, its total orders rose 71% organically to $18.3 billion. Its backlog reached $163 billion. As seen above, its electrification segment booked $2.4 billion of data-center-related equipment orders in just one quarter. That is big: we see customers fighting for transformers, switchgear, grid equipment, and power infrastructure.
The macro numbers reinforce it. BloombergNEF put global grid investment at $483 billion in 2025. The IEA expects electricity supply and infrastructure investment to reach $1.6 trillion in 2026, or around $2 trillion if we include end-use electrification. E2 also tracked more than 50 new U.S. utility-scale generation and storage project announcements in Q1 2026, totaling over 12 GW and $18 billion of investment.

Is AI helping climate tech, or pushing us back to gas?
AI is helping climate tech companies that sell power infrastructure, but it is also making the emissions story messier.
The growth side is obvious.
Data centers are now one of the biggest new sources of electricity demand. That demand makes grid equipment, firm power, storage, cooling, energy management, and clean power procurement more urgent. GE Vernova’s $2.4 billion of Q1 2026 data-center electrification orders is the cleanest proof that AI is becoming a real demand channel for energy infrastructure.
But the climate side is not automatically positive.
AI power demand can be served by renewables, nuclear, geothermal, storage, and grid upgrades. It can also be served by gas turbines and fossil-heavy grids. That is why the AI-climate story is something like “AI will force the power system to expand, and the technology mix will decide whether that expansion is clean.”
We also see a practical bottleneck. GE Vernova’s CEO acknowledged in May 2026 that some data-center customers are struggling to get projects approved because of state and community pushback. It actually confirms how intense the buildout is becoming. If communities are pushing back, it means projects are real enough to create local friction.
So AI is a tailwind for energy and grid climate tech, but not automatically a tailwind for decarbonization.
Are EVs still growing, or did the slowdown become real?
EVs are still growing globally, but the market is no longer moving evenly.
The global number is strong. Electric car sales topped 20 million in 2025, up 20% from 2024, and reached one in four new cars sold worldwide. That means EVs are not a stalled category. A 20% growth rate on a 20 million-unit base is still a large amount of incremental demand.
Europe is also showing fresh momentum. In Q1 2026, battery-electric car sales in Europe rose 26.2% year over year across the EU, EFTA, and UK, with March up 41.7%. In the EU alone, Q1 BEV sales rose 32.5%. That is recent acceleration.
But the U.S. is weaker. Tax credit changes, lower consumer sentiment, and policy uncertainty are making the U.S. EV signal less clean. Volvo’s recent commentary is a good example of the split: weaker demand in the U.S. and China, but continued electrification growth in Europe. China remains structurally strong, but the market there is brutally competitive, which pressures margins even when volumes grow.
So EVs are still growing, but there is regional divergence: Europe and China still carry the market, while the U.S. is less reliable.

Is solar still booming, or only utility solar?
Solar is still booming globally, but the U.S. residential solar channel is not.
Global solar deployment is one of the strongest climate tech signals. IRENA’s 2026 renewable capacity data shows that solar added 511 GW in 2025, accounting for roughly three-quarters of all new renewable capacity.
That is a massive scale number. When one technology adds more than 500 GW in a year, it is clearly not a niche market.
India gives a second useful signal because it shows growth outside the usual China-Europe-U.S. framing. India added a record 44.5 GW of renewable capacity in 2025 through November, nearly double the same period in 2024. Solar accounted for about 35 GW. That tells us solar growth is not only a Western subsidy story.
But residential solar in the U.S. is clearly weak. Enphase reported that U.S. revenue fell 23% quarter over quarter in Q1 2026, while U.S. sell-through fell 48% sequentially and 18% year over year. Management directly linked the drop to the expiration of the federal residential clean energy tax credit and seasonality. Not a small wobble.
So the answer depends on which solar market we mean. Utility-scale and global solar are still expanding. U.S. residential solar is in a demand shock.
If you want more recent data on this point, please see our latest climate tech market report.
Is climate manufacturing scaling, or getting cancelled?
Climate manufacturing is scaling in some places, but the U.S. signal has become materially worse.
The positive side is visible in Europe and India. The EU’s Net-Zero Industry Act targets domestic manufacturing capacity for strategic net-zero technologies at around 40% of annual deployment needs by 2030.
The EU Clean Industrial Deal also pushes decarbonization as an industrial competitiveness policy, not just a climate policy. India’s record renewable additions also suggest demand for equipment and local supply chains is deepening.
But U.S. manufacturing has become a warning signal. EDF and Atlas Public Policy reported $1.4 billion of cancelled clean energy manufacturing investments and 8,100 jobs lost in Q1 2026. E2’s Q1 2026 tracking also showed that clean energy generation and storage project announcements remained strong, but cancellations and project losses were mounting.
This split is important. It looks like policy stability matters more in manufacturing than in software. A factory needs multi-year confidence. If tax credits, tariffs, foreign entity rules, and domestic content requirements shift too fast, companies pause or cancel.

Is green hydrogen finally happening?
Green hydrogen is happening in narrower places than promised. The broad hype cycle is over.
The negative signals are too large to ignore.
Fortescue cancelled its Arizona hydrogen project and its Gladstone PEM50 project in 2025, even though both had previously been treated as serious projects. The company cited policy shifts and strategic changes. Australia’s larger hydrogen ambitions also saw stress, including the collapse of major export-oriented projects where costs, funding, and offtake did not work.
The pattern is not just one company. Green hydrogen projects are struggling when they depend on optimistic demand, cheap renewable power, new infrastructure, and subsidy certainty all at once. That is a hard stack. If one piece breaks, the project stops making sense.
But hydrogen is not dead.
Industry reviews still show hundreds of projects globally that are past final investment decision, under construction, or operating, with large committed investment. The surviving market is more disciplined: industrial hydrogen, ammonia, refining, steel, ports, and locations with strong renewable resources or policy support.
Is carbon removal becoming real, or still a Microsoft market?
Carbon removal is becoming more real, but the buyer base is still too concentrated.
The strongest signal is recent contracting volume. Durable CDR hit its largest Q1 on record in 2026. CDR.fyi reported 2.3 million tonnes contracted in Q1 2026, around 560% of Q1 2025 volume. ClimeFi reported 1.86 million tonnes of durable CDR contracts in Q1 2026, up 138% from Q1 2025.
Different trackers use slightly different methodologies, but both show strong acceleration.
The second signal is buyer broadening, but only partially. CDR.fyi reported that Microsoft led Q1 2026 with a 1 million-tonne agreement, while more than 113 other purchasers contracted 1.3 million tonnes. That is encouraging because it means the market is not literally one buyer. But Microsoft is still too important to ignore.
The third signal is consolidation. Terradot acquired Eion in early 2026, combining enhanced rock weathering assets, contracts, people, and IP. That is what happens when a market moves from experiments to delivery pressure. Buyers want tonnes that can be measured, verified, financed, and delivered.
So CDR is growing. But it is not yet a broad, liquid commodity market. It is still a high-conviction buyer market with heavy delivery risk.

Are companies cutting climate budgets, or just renaming them?
These days, companies are not abandoning every climate budget. However, they are renaming and reprioritizing them.
This is one of the most important market shifts. MSCI’s 2026 sustainability outlook says green technology is advancing more on commercial strength than policy support, while physical climate risk is becoming more financially material. SVB’s 2026 climate tech report also frames the market around federal policy headwinds, electrification demand, AI power needs, and a profitability pivot.
The language shift here matters. In 2021, companies bought climate tech because net-zero commitments were fashionable and capital was cheap. In 2026, they buy because power is scarce, insurance risk is rising, factories need resilience, and customers want cheaper energy. The budget did not vanish, but it did move from ESG storytelling to operations, finance, risk, and infrastructure.
The weak side is that “nice-to-have” sustainability tools are more exposed. If a product only helps reporting or branding, it may face budget pressure. If it reduces energy bills, unlocks grid capacity, lowers insurance risk, or helps comply with hard rules, it has a better chance.
So climate demand is not disappearing, but, yes, it is becoming less sentimental and more CFO-driven.
If you want more recent data on this point, please see our latest climate tech market report.
Are climate bankruptcies a one-off, or a pattern?
Climate failures are now part of the market pattern, especially in hardware-heavy categories.
Northvolt is the clearest example. Its 2025 bankruptcy was not just a company story but a warning that battery manufacturing is brutally hard: factories are expensive, quality problems compound quickly, customers can lose confidence, and funding gaps become fatal.
The U.S. clean manufacturing data points in the same direction. Q1 2026 saw $1.4 billion in cancelled clean energy manufacturing investment and 8,100 jobs lost. E2 also reported continuing project cancellations, closures, and downsizes, even while new generation and storage projects were still being announced.
Hydrogen adds another failure signal. Projects that looked credible two years ago are getting cancelled when policy, costs, and buyers do not line up. That is a pattern across climate hardware: announcements are cheap, final investment decisions are harder, and commercial operation is hardest.
This chart, featured in our climate tech market deck, shows how personal carbon tracking app technology has evolved over time
Is policy helping climate tech right now?
Policy is helping in Europe and parts of Asia, but hurting several U.S. climate tech segments.
To be honest, the U.S. signal has turned much less friendly.
The One Big Beautiful Bill Act changed the clean energy tax credit landscape after July 2025, including accelerated phaseouts, tighter rules, and early endings for several consumer-facing incentives. The impact showed up quickly in residential solar: Enphase’s Q1 2026 U.S. sell-through dropped sharply after the residential clean energy credit expired.
The U.S. impact is not only consumer demand. Manufacturing and project finance also became more complicated because developers now have to manage tighter deadlines, domestic content requirements, foreign entity restrictions, and tariff uncertainty. That increases the cost of moving from announcement to construction.
Europe is moving differently. The EU Clean Industrial Deal and Net-Zero Industry Act are trying to make clean tech part of industrial competitiveness. The 40% domestic manufacturing target is a clear demand signal for European supply chains. India’s renewable buildout also shows policy and economics reinforcing each other.
So policy is not globally anti-climate. It’s confusing though.
Is M&A showing confidence or distress?
M&A is showing both, which is what happens when a market matures.
Some deals show confidence. Strategic buyers and large infrastructure players are buying assets because clean power, grid, storage, and energy resilience are becoming core businesses. In India, Inox Clean Energy’s acquisition of roughly Rs 25,000 crore of renewable assets shows how large players are consolidating capacity to become bigger clean energy platforms.
Other deals look more like cleanup. Terradot’s acquisition of Eion in carbon removal shows a young market consolidating around stronger delivery platforms. That can be healthy, but it also tells us smaller suppliers may struggle to finance measurement, verification, project execution, and long-term delivery.
The broader renewable M&A market also shows discipline rather than frenzy. High capital costs, supply-chain rules, and U.S. policy uncertainty make buyers more selective. That means fewer “growth at any price” deals and more asset-quality filtering.
So M&A is not a simple bullish signal. It says climate tech is leaving the experiment phase. Strong players are buying scale. Weak players are running out of room.

Are patents and new startups still a useful growth signal?
Innovation is still active, but patents and startup counts are weaker proof than deployment.
StartUs Insights tracks more than 55,000 climate tech companies, more than 2,400 startups, and over 3.3 million patents in its 2026 climate tech report. That is a large innovation base. It tells us climate tech is not intellectually dead. There is still deep work happening across energy, materials, agriculture, carbon, water, buildings, and industrial systems.
But this signal has limits. Patent counts and startup databases are slow-moving. They do not tell us whether a buyer signed this quarter, whether a project reached FID, or whether a factory can produce at quality. In climate tech, commercialization is often the bottleneck, not invention.
The more useful interpretation is that innovation supply remains broad, while market demand is narrowing around fewer use cases. The technologies closest to power constraints, cost savings, resilience, and regulatory compliance have a clearer path. The rest may still be interesting, but they need more patience.
So converting innovation into bankable deployment is the current problem.
So, is the climate tech market growing right now?
Yes, climate tech is growing right now, but the growth is concentrated and more brutal than before.
The evidence is strongest in deployment. Energy transition investment is at a record level. EV sales are still growing globally. Solar additions are huge. Grid investment is rising. Public companies tied to power infrastructure and utility-scale solar are reporting strong demand. Carbon removal contracting is accelerating from a small base. Resilience and adaptation are becoming more practical buying categories.
The evidence is weakest in venture breadth, U.S. residential solar, green hydrogen, subsidy-sensitive manufacturing, and capital-intensive startups that still need years of financing before proving demand. Those parts are not just “slowing.” Some are actively shrinking, resetting, or consolidating.

OUR METHODOLOGY
This analysis tests whether the climate tech market is growing now based on recent evidence across funding, customer demand, deployment, AI, grid infrastructure, EVs, solar, manufacturing, hydrogen, carbon removal, policy, bankruptcies, M&A, and innovation signals.
We did not treat climate tech as one single market. The analysis separates global solar from U.S. residential solar, global EV growth from U.S. softness, grid demand from broader venture weakness, and carbon removal contracting from buyer concentration.
For each dimension, we prioritized recent signals that showed actual market behavior. Orders, investment, contracts, capacity additions, sell-through, cancellations, bankruptcies, policy changes, and public-company results carried more weight than long-range forecasts or general market commentary.
Analyst forecasts were used as directional evidence for the long-term demand pool, not as proof of what is happening right now. That matters because climate tech forecasts can define the market differently, from software and services to broader energy transition investment.
Deployment evidence was treated as the strongest growth signal. This includes energy transition investment, EV sales, renewable capacity additions, grid investment, public-company orders, solar backlogs, and carbon removal contracts.
Funding evidence was interpreted with caution. Climate startups are still raising, but the capital market has become more selective, so total dollars matter less than where investors are deploying capital and which categories are still getting conviction.
Policy evidence was evaluated by geography because the climate tech policy signal is no longer uniform. Europe and India show more supportive industrial and deployment signals, while several U.S. segments face more uncertainty and demand pressure.
We treated bankruptcies, cancellations, and M&A as part of the growth picture, not as separate negative anecdotes. In hardware-heavy climate tech, failures can reveal whether a category has moved from announcement-driven hype to execution-tested demand.
The final view comes from aggregating those signals across the main dimensions, then looking for where the evidence converges. The clearest conclusion is that climate tech is still growing where it solves immediate economic, infrastructure, or operating problems, and much weaker where demand still depends on cheap capital, unstable subsidies, or buyers paying mainly for green positioning.
