Written by Lindsay Li | 4/6/26 11:00 AM

2026 is shaping up to be a defining year for how organizations turn climate commitments into operational reality. New research points to the broader environmental footprint of AI systems, including water use and carbon intensity at scale, highlighting how rapid adoption is placing additional strain on infrastructure, from electricity grids to local water resources.

With these challenges in mind, climate tech is attracting significant investment in areas where companies can demonstrate real-world impact and viable paths to scale. From building decarbonization and grid intelligence to carbon accounting and advanced materials, companies are delivering real results.

Below, we highlight 14 companies that combine strong science with practical execution: solving specific, high-impact problems and showing measurable progress through deployed systems, growing customer bases, and quantifiable emissions reductions.

Energy CX

Location: Chicago. IL

Managing energy has become increasingly complex for businesses navigating volatile markets and evolving sustainability expectations. Energy CX is rethinking the energy management process with a data-driven platform that helps organizations treat energy like an investment rather than a fixed expense. By combining proprietary analytics with market expertise, the company enables customers to make more informed purchasing decisions, reduce risk, and optimize long-term energy spend. The company supports a broader shift toward cleaner energy by helping organizations implement sustainability strategies, from renewable energy purchasing and carbon offsets to EV charging and on-site solar. With more than 100,000 service locations and an average of 20% savings for customers, Energy CX is demonstrating how better data, transparency, and execution can drive both cost efficiency and lower-impact energy use at scale.

 

75F

Location: Bloomington, MN

75F is an IoT building management platform that combines hardware, software, and machine learning to optimize HVAC performance to reduce energy consumption in commercial buildings. Backed by institutional investors and deployed across commercial portfolios globally, 75F has demonstrated measurable energy savings for building operators. Deployments of its devices and connected software can reduce building energy consumption by 20–30%, translating into significant emissions reductions across large commercial portfolios.

 

Encamp

Location: Indianapolis, IN

Staying compliant with environmental regulations is a growing operational burden for large organizations. Encamp modernizes environmental compliance with a software platform that automates reporting, tracks regulatory requirements, and centralizes data across facilities. By replacing spreadsheets and fragmented workflows with a system of record, the company helps organizations reduce risk, improve accuracy, and ensure timely reporting. Beyond compliance, Encamp enables better environmental decision-making by giving companies clearer visibility into their data, supporting more proactive management of emissions, waste, and environmental impact.

 

Sortera Technologies

Location: Markle, IN

Extracting critical minerals from low-grade and complex sources has historically been inefficient and resource-intensive. Sortera Technologies is working to change that by enabling the recovery and reuse of metals from end-of-life products, helping close the loop on material supply. The company combines advanced imaging, machine learning, and real-time decisioning to divert billions of pounds of material from being exported overseas while reducing the energy required for aluminum production by up to 95% compared to virgin manufacturing. In late 2025, the company raised $45 million to accelerate its growth as a domestic supplier of upcycled metals, helping strengthen more resilient and lower-carbon supply chains.

 

 

 

 

 

 

 

 

 

RoadRunner

Location: Pittsburgh, PA

RoadRunner is addressing the fragmented and inefficient experience of waste management to help businesses control costs, track environmental impact, and move toward zero waste. The company’s technology-enabled platform connects businesses to a nationwide network of independent haulers, streamlining operations and improving visibility into waste and recycling performance. Using data to optimize routing, reduce unnecessary pickups, and increase diversion from landfills, RoadRunner helps customers lower costs while improving sustainability outcomes. With a focus on efficiency, circularity, and measurable impact, the company is modernizing waste management infrastructure, turning what has traditionally been a back-office function into a more strategic, data-driven part of operations.
