The global market for compressed natural gas (CNG) and liquefied petroleum gas (LPG) vehicles is projected to grow significantly over the next five years, driven by stricter environmental regulations, rising fuel costs, and increasing demand for cleaner transportation alternatives.
According to a new industry report released by Research and Markets, the global CNG and LPG vehicle market is expected to expand from USD 6.72 billion in 2025 to USD 10.25 billion by 2031, registering a compound annual growth rate (CAGR) of 7.29%.
The report highlights that governments worldwide are intensifying efforts to reduce greenhouse gas emissions and urban air pollution, encouraging consumers and commercial fleet operators to adopt alternative fuel vehicles. CNG and LPG-powered vehicles are gaining popularity due to their lower operating costs and comparatively cleaner emissions than conventional petrol and diesel vehicles.
India has emerged as a major growth market for CNG vehicles. The report noted that Tata Motors recorded a 35% increase in CNG vehicle sales during FY2025, supported by the upcoming implementation of stricter CAFE 3 emission standards in 2027. Industry data also showed that the share of CNG vehicles in India rose from 17.8% in 2024 to 21.2% in 2025, signaling a strong shift toward cost-effective fuel alternatives.
Analysts said affordability remains one of the strongest drivers of market expansion. CNG vehicles in India reportedly offer fuel savings of nearly 40% compared to equivalent petrol-powered models, making them increasingly attractive amid volatile fuel prices.
Despite strong growth prospects, infrastructure limitations continue to pose a major challenge. The report warned that inadequate refueling networks, especially for CNG vehicles, are slowing broader adoption across several regions. In the United States, for example, only 1,385 CNG stations and 81 LNG stations were operational by the end of 2025, limiting vehicle range and operational convenience.
Another major trend shaping the industry is the increasing involvement of original equipment manufacturers (OEMs). Automakers are expanding factory-fitted CNG and LPG vehicle offerings to address concerns linked to aftermarket conversions while improving safety, reliability, and warranty support.
The industry is also witnessing growing investments in renewable fuels such as Bio-CNG and renewable liquid gas. According to the report, renewable natural gas production in the United States increased by 24% in 2025, enough to power approximately 8.2 million vehicles.
