Climate Tech is technology built for one purpose: to confront climate change directly. That means cutting greenhouse gas (GHG) emissions, removing carbon that is already in the atmosphere, or helping people and infrastructure adapt to a hotter, more volatile climate. It spans nearly every industry — energy, transport, agriculture, manufacturing, buildings, and finance — but what ties it together is intent. A technology counts as climate tech when it is designed, first and foremost, to slow climate change or to deal with its consequences.
The reason it matters is a matter of arithmetic. The world has committed to reaching net-zero emissions by mid-century, but the International Energy Agency estimates that around 40% of the emissions cuts needed to get there rely on technologies that have not yet been scaled into everyday use. Pledges and policy set the direction; climate tech is what actually closes the gap between ambition and reality. For businesses and investors, it has also become one of the most closely watched investment sectors of the decade — though it has been through both a boom and a sharp cooling-off, and profitability is far from universal across the field.
The three areas of Climate Tech
Most frameworks organize the field into three broad areas, plus a fast-growing layer that supports all of them:
Mitigation is the largest and most mature area — technology that prevents emissions from happening in the first place. This includes renewable energy generation, battery and energy storage, smart grids, electric vehicles and e-mobility, sustainable fuels, low-carbon industrial processes, and climate-smart agriculture. Because energy and transport account for the bulk of global emissions, this is where most of the activity and capital sits.
Carbon removal deals with carbon already in the air. Approaches range from nature-based methods like reforestation, biochar, and soil carbon sequestration to engineered solutions such as Direct Air Capture (DAC) and Bioenergy with Carbon Capture and Storage (BECCS). The IPCC has concluded that some level of carbon removal is unavoidable to balance emissions that are hard to eliminate, though many of these methods are still costly and early-stage.
Adaptation and resilience prepare communities and infrastructure for impacts that are already locked in — flood and wildfire sensing, heat-resistant crops, climate-resilient building materials, drought management, and climate-risk modeling.
Running through all three is an enabling layer: carbon measurement, accounting, and management software. It is an increasingly important and growing segment for a simple reason — organizations cannot reduce what they cannot accurately measure.
Where Climate Tech stands globally in 2025–2026
After two years of decline, the sector has steadied and matured rather than surged back. Global venture and growth investment reached about US$40.5 billion in 2025, an 8% increase on the previous year — the first uptick after a cooling-off period. The character of that money has changed, though: investors are now writing larger checks to fewer, more proven companies, and early-stage deal counts have kept falling into early 2026, prompting many to describe a market that now rewards “proof over promise.”
The regional picture is uneven. The United States remains, by far, the largest destination for climate tech startup funding — US funding rose 27% in 2025 on the back of large data-center, nuclear, and EV deals, reinforcing its role as the sector’s hub; yet investment in large-scale clean-tech manufacturing in the US has fallen for several consecutive quarters amid policy uncertainty. Europe saw startup funding slide to roughly US$10.1 billion (its lowest since 2020), but it led the world in new climate-fund formation, accounting for over half of all climate-fund capital raised that year. Asia, and China in particular, anchors the mass manufacturing and deployment of clean technology — solar panels, batteries, and electric vehicles. In short, the global market is increasingly fragmented by policy and regional maturity.
The defining theme of this period is artificial intelligence. AI is both a major new driver of electricity demand — through the explosive growth of data centers — and one of the most powerful tools for optimizing grids, forecasting renewable output, and accelerating the discovery of new materials. Nearly 28% of all climate-equity dollars in 2025 went to AI-related solutions. In short, climate tech has moved past its hype phase into a more disciplined, deployment-focused era that many see as a sign of long-term health.
Climate Tech in Thailand
Thailand has a growing and increasingly active climate tech ecosystem, with Bangkok as the main hub for activity within the country. Across Southeast Asia as a whole, however, the clear leaders are Singapore — the region’s innovation and finance hub, home to nearly half of its green-economy startups — and Indonesia, which captured roughly 67% of ASEAN’s climate tech funding in 2024 on the back of its EV ecosystem. Together, Singapore and Indonesia account for more than 90% of the region’s climate tech deal value. Thailand sits in the smaller-market group alongside Vietnam, Malaysia, and the Philippines, though it is developing in earnest.
On targets, the country historically aimed for carbon neutrality by 2050 and net-zero emissions by 2065. In its third Nationally Determined Contribution, submitted in October 2025, Thailand aligned with the 1.5°C pathway and pulled its net-zero target forward to 2050 — fifteen years earlier than before — while pledging to cut net GHG emissions by 47% by 2035 against 2019 levels, conditional on international support. The transition is estimated to need around US$7 billion in investment by 2035.
The ecosystem is being built quickly. Thailand drew roughly US$355 million in private green investment in 2024, and a widening community of startups now gathers each year at the Decarbonize Thailand Symposium, hosted at True Digital Park across e-mobility, decarbonization, agritech, energy, and the built environment. New Energy Nexus has also run “Climate Tech Lab to Market,” described as the country’s first climate tech commercialization program. Homegrown examples give a flavor of the range: GeoAgni develops closed-loop geothermal power for round-the-clock clean energy; SkyCool makes a passive radiative cooling film that keeps surfaces several degrees below ambient temperature and cuts air-conditioning load; AltoTech uses AI and IoT to optimize energy in hotels, buildings, and factories; and Vekin builds emissions-calculation and carbon-offset platforms.
The picture is not without friction. The sector still contends with regulatory hurdles, a shortage of skilled talent, and limited local funding — challenges that will shape how fast Thailand can turn its sharpened net-zero ambitions into deployment on the ground. Supporting structures help, including the SEC’s 56-1 One Report disclosure requirement and the T-VER voluntary carbon credit program administered by the Thailand Greenhouse Gas Management Organization (TGO), which lets verified emission-reduction projects earn tradable domestic credits. T-VER is the country’s most developed carbon market, but it remains voluntary with relatively limited activity, and Thailand still has no mandatory carbon tax or emissions trading scheme (ETS) — though in late 2025 the upgraded Premium T-VER standard was approved by the ICAO for airlines to use under the CORSIA scheme, a notable step toward linking Thailand’s carbon market to international standards.
How Climate Tech is reshaping technology operations
For technology teams, climate tech cuts in two directions at once. It puts IT operations under scrutiny — data centers, cloud workloads, and AI training consume enormous and rapidly rising amounts of power — pushing organizations toward energy-efficient hardware, smarter cooling, virtualization, renewable-powered facilities, and responsible handling of electronic waste.
At the same time, technology is the engine that makes climate action possible. IoT sensors, big-data analytics, AI, and digital twins turn invisible emissions into measurable, manageable numbers — tracking energy use in real time, predicting equipment failures, optimizing consumption, and powering the carbon-accounting platforms that reporting now depends on. As climate disclosures become mandatory in more markets, the quality and auditability of that data turn into a core technical responsibility, raising the bar for transparent reporting and secure data management.
What Climate Tech unlocks for businesses
Beyond its environmental purpose, climate tech has become a practical business advantage. Energy efficiency, on-site renewables, and smarter resource use lower operating costs and reduce exposure to volatile energy prices and carbon pricing. Companies that deploy credible climate solutions are better placed to attract sustainability-minded investors and tap into green finance. Verifiable climate action — measured, not merely marketed — builds trust with customers who increasingly choose where to spend based on values. And early movers can turn decarbonization into new products, services, partnerships, and even revenue through carbon credits, positioning themselves as leaders rather than followers as the transition accelerates.
The thread connecting all of these is durability: climate tech helps a business cut cost and risk today while building the resilience and reputation it will need as climate expectations tighten over the years ahead.
Netka EnXus: A Carbon Management Platform for Sustainability
Within the “enabling layer” of carbon measurement and reporting described above, Netka System has developed a tool of its own: Netka EnXus, an environmental sustainability management platform (a Carbon Accounting & Management Platform) that helps organizations measure, monitor, reduce, and report greenhouse gas (GHG) emissions in a systematic way. It supports the assessment of Scope 1, 2, and 3 emissions in line with ISO 14064-1 and the GHG Protocol.
Netka EnXus comes with capabilities that cover every stage of carbon management: GHG Inventory Reports with dashboards that track both historical and real-time emissions; export to the TGO (Thailand Greenhouse Gas Management Organization) report template to reduce human error and ease the verification process; GHG Project management aligned with ISO 14064-2; data collection both manually and automatically via APIs integrated with IoT sensors; predictive analytics using machine learning to forecast the year an organization will reach carbon neutrality and net zero; and a GHG Inventory Diagram that visualizes emissions across every process in the organization in a single view.
In short, Netka EnXus helps organizations turn complex emissions data into manageable numbers and reduce the workload of collecting and verifying that data.
