Electric Vehicles Reduce Climate Pollution, New Study Finds

A study from the University of Michigan found that battery electric vehicles have lower lifetime greenhouse gas emissions than internal combustion engine vehicles, hybrids, and plug-in hybrids in every county in the contiguous US. The analysis provides estimates of emissions per mile driven across 35 different combinations of vehicle class and powertrains, and a free online calculator allows drivers to estimate their emissions based on their vehicle, driving habits, and location. The study aims to help drivers, the automotive industry, and policymakers understand the benefits of vehicle electrification in reducing climate pollution.

The global electric vehicle (EV) battery coolant market is experiencing robust growth, poised to reach a market valuation of US$ 2,848.1 million by 2033, according to a recent study by Astute Analytica [1]. The market is driven by several key factors, including the increasing demand for longer EV driving ranges, stringent government regulations on vehicle emissions, and advancements in high-energy-density battery technology.

The study reveals that the market is witnessing a significant competitive resurgence, with five dominant companies—BASF SE, Valvoline Inc., Exxon Mobil Corporation, Shell Group, and GS Caltex—leading the market direction. These companies are continually investing in innovative product rollouts and global expansion. Top battery cooling system makers such as MAHLE, Valeo, Dana, Modine, Hanon Systems, and Bosch also remain at the forefront of new system launches.

The Asia-Pacific region is the leading market for EV battery coolants, driven by rapid EV sales in China, Japan, and India. Europe and North America display signs of market maturity, while regions like South America and the Middle East & Africa show promising growth. Major players such as ExxonMobil, BASF, Shell, and TotalEnergies are leveraging their distribution capabilities and chemical expertise to enhance their market position.

One of the key trends in the market is the growing adoption of advanced direct-liquid and immersion cooling technologies. Additionally, the integration of AI and machine learning for smart thermal management is becoming increasingly common. There is also a strong focus on developing sustainable, eco-friendly coolant formulations with low conductivity to align with global emissions compliance.

However, the market also faces several challenges, such as high initial investment costs associated with advanced thermal management systems and the technical complexity of integrating cooling systems into compact EV architectures. Managing the environmental impact and recyclability of battery coolant materials is another significant challenge.

The market is seeing major technological leaps, with advanced liquid cooling now the industry standard, adopted by eight out of ten leading OEMs. Glycol-based coolants, particularly ethylene glycol variants, are experiencing a compound annual growth rate of 27.6%. Phase-change materials (PCMs) made their commercial debuts in battery thermal management, achieving higher energy efficiency. Global patent filings for emerging coolant technologies reached at least 25 in 2024 and 2025.

OEM partnerships play a crucial role in driving market growth. Elite suppliers such as BASF, Shell, and Valvoline have secured custom coolant supply agreements with major EV brands like Tesla, BYD, Hyundai, and Volkswagen. These partnerships have led to the launch of eleven brand-new proprietary coolant formulas since January 2024.

The market also shows dynamic product diversity, with non-conductive, dielectric coolants accounting for 17% of new applications in 2025. Hybrid coolants, blending glycol and advanced chemical additives, feature in 28% of EV model launches. Research and development activity is surging, with leading players ramping up thermal management research budgets by a joint 18% in one year.

The study highlights that the electric vehicle battery coolant market is keenly influenced by battery chemistry trends. As of 2025, 61.3% of all EVs utilize lithium-ion battery chemistries, directly driving up corresponding coolant demand. Solid-state battery innovation advanced significantly, with a 14% increase in prototypes requiring thermal solutions over the last year.

The evolving regulatory landscape is reshaping the market, with 32 countries adopting tighter thermal runaway and coolant performance standards for battery systems by August 2025. This has led to a significant reduction in battery thermal runaway incidents, demonstrating the market's commitment to safety innovation.

The market's commitment to digital integration and regional supply resilience is evident, with smart, sensor-controlled applications now standard in 43% of new BEVs. Cooling plates anchored in battery packs feature in 35% of vehicle launches, and dual-stage cooling appears in 19% of R&D-stage vehicles for 2025.

In conclusion, the electric vehicle battery coolant market is experiencing significant growth, driven by technological advancements, regulatory pressures, and strong OEM partnerships. The market is expected to continue its upward trajectory, with a projected market valuation of US$ 2,848.1 million by 2033.
