GreenIRR CEO Explains How Fuel Efficiency, Carbon Emissions Are the Same Number In Trucking

Celine King, CEO of Brown and White Ventures portfolio company GreenIRR, explains how, in trucking, a carrier’s fuel bill and its carbon emissions aren’t two metrics that happen to move together. They’re the same measurement in two units. Burning a gallon of diesel produces a fixed quantity of CO2, about 22.4 pounds by the EPA’s factor, and that ratio never changes, because it’s chemistry rather than policy. Diesel is roughly 87% carbon, combustion turns that carbon into CO2, and the molecular weights do the rest. So every gallon a fleet saves shows up twice: once as dollars, once as carbon. That matters because fuel is one of the two largest costs a carrier carries. In ATRI’s latest data, fuel ran 48 cents per mile in 2024, about 21% of the $2.26 cost of operating a truck, and closer to a quarter in higher-price years. Back the numbers out and one gallon is worth roughly $3 and about 0.01 metric tons of CO2e. Trim 1,000 gallons off a lane and you save on the order of $3,000 and avoid about 10 metric tons of CO2e, from the same action. Efficiency and decarbonization aren’t competing for budget. They’re one project with two reporting lines. The room to move is real. The average Class 8 truck gets about 6.3 mpg while newer aero-spec trucks have demonstrated 9-plus mpg in on-road testing. A tractor running 100,000 miles a year at 6 mpg versus 7.5 burns about 3,400 more gallons, worth roughly $10,000 and about 34 metric tons of CO2e per truck. The levers, aerodynamics, tires, idle reduction, routing, and fleet age, are ordinary operational decisions, and each gallon they save lands on both ledgers in the same 22.4-pound proportion. The strategic upshot for shippers: you don’t have to choose between a cheaper carrier and a cleaner one. On diesel freight, the efficient carrier is both, and fuel efficiency is the shared signal. It’s also why the GHG Protocol’s fuel-based method beats distance-based estimates, since the same fuel data that runs a carrier’s cost model produces a defensible Scope 3 number for the shipper. Pay for verified gallons per ton-mile and you’re buying lower cost and lower emissions in one transaction. Get the operational number right and the carbon number is already there, in the same units. Efficiency is the lever. Carbon is what the lever also moves.

Counsel Stack Connecting Legal Citator to Claude for Advanced AI-Powered Research

Counsel Stack announced its next advancement in AI-assisted legal research: the successful integration of its proprietary citator with Claude. This development marks a step forward in how legal professionals can leverage large language models (LLMs) to perform complex, grounded legal research and litigation workflows. By connecting Counsel Stack’s citator to Claude, the platform now enables the AI to research with the precision of a lawyer. The integration allows Claude to access and navigate Counsel Stack’s massive 200-million-edge citation graph, providing users with answers backed by direct, verifiable links to legal sources. "We connected Counsel Stack's citator to Claude. It researches like a lawyer, based on our prompting, and provides answers with links. Counsel Stack helps Claude find relevant legal sources and crawl around our 200m edge citation graph," said Von Wooding, CEO of Counsel Stack. This integration goes beyond simple search queries. It is designed to support sophisticated litigation workflows, including editing and redlining legal briefs, all while remaining grounded in curated, high-quality legal data. The system currently operates via a local Model Context Protocol (MCP) server, utilizing a robust 250GB dataset that includes over 50 million citations, ranging from federal statutes and regulations to state constitutions and agency enforcement actions. The company is also exploring the future of local, private legal AI. Counsel Stack has successfully tested the system with 27-billion-parameter local LLMs, demonstrating that high-performance legal research can be achieved without relying on third-party cloud services. "In the very near future you will be able to run a ~120 IQ LLM on your own machine, calling on local legal data that is updated daily from an oracle, and can answer most legal questions without connecting to a third party service," Wooding added. While the current primary bottlenecks for local deployment remain hardware-related—specifically the cost of vRAM and token throughput—Counsel Stack is actively optimizing its architecture to overcome these challenges. The company is also preparing to announce further integrations, including a connection to the Mike OSS front end, which is purpose-built for legal applications. This development positions Counsel Stack at the forefront of the "private AI" movement in law, offering firms the ability to maintain data sovereignty while utilizing cutting-edge research tools. As the legal industry continues to grapple with the balance between AI efficiency and data security, Counsel Stack’s approach offers a compelling path forward. Counsel Stack provides advanced legal technology infrastructure, specializing in citation graphs and AI-driven research tools designed to empower legal professionals with accurate, grounded, and efficient workflows. It is a portfolio company of Brown and White Ventures.
