The use of gas (CNG or Biomethane) as fuel in light and heavy vehicles is one of the solutions found as an alternative to gasoline and diesel with the aim of reducing pollution.
In Rio de Janeiro, the use of CNG in passenger vehicles is common, being a solution based on the cost-benefit of the product and currently helping to combat GHG (greenhouse gases).
Through Environmental Governance (ESG), companies have been demanding an “environmentally correct” behavior from the market. With that in mind, as an alternative to diesel and gasoline, it is possible to observe some trucks and agricultural machines powered by gas. This technology, which utilizes Otto cycle engines, allows the use of both CNG (fossil fuel, but less polluting) and Biomethane (gas obtained through anaerobic fermentation of organic material).

With installments starting from R$ 999 per month, a 75 hp 1.0 engine, a 7-inch TFT digital panel, and standard stability control, the Citroën C3 is the cheapest hatchback in Brazil in 2026 and still leaves Kwid, Argo, and Mobi behind in onboard technology.

Toyota slashes the price of the Corolla Hybrid by more than R$ 45 thousand and surprises the market by facing the BYD Song with an unprecedented aggressive strategy in Brazil.

A 16-wheel truck is visually striking and impresses with its engineering: Tatra Phoenix 16×16 becomes a “giant centipede” and redefines limits in extreme terrains and heavy operations.

Caoa Changan is preparing two new national SUVs for 2026 in Anápolis, with a 1.5 turbo flex engine of up to 192 cv and a proposal to expand its line in Brazil beyond the Uni-T.
The graph below shows the evolution of heavy vehicles powered by gas in 2021.

The Companies That Have Opted for This Market Niche Are Betting That:
- Gas Will Be a Transition Element Until Electrification;
- The Replacement of CNG by Biomethane in Specific Locations Could Be a Market Niche, Such as Sugarcane Mills That Use Sugarcane Bagasse and Vinasse to Produce Biomethane and Subsequently Fuel Their Fleets;
- Getting Ahead in the Process of Reducing Pollutant Emissions by Associating with “Green” Companies That Care About the Environment.
It is worth noting that the heavy vehicles we see circulating in the fleet with this technology were already developed in Europe and comply with the EURO VI standard (which will come into effect in Brazil in
2023). According to experts, vehicles that come with factory gas engine technology are 100% reliable regarding emission standards. However, vehicles that make adaptations must do so at specialized companies to ensure that the adaptation meets emission standards.
To promote the use of this fuel in Brazil, several actions are necessary, and among them, we highlight the two that generate the most debates:
- Infrastructure for Gas Pipelines,
- Tax Incentives for the Price of Gas.
The potential of Biomethane in Brazil is very large, still underexplored, but the mapping of possibilities has already been raised by sector associations.
Today, the country wastes 100 million m³ of renewable methane per day, which is equivalent to 35% of the electricity consumed in Brazil and 70% of diesel. The sugar-energy sector accounts for 50% of the potential of biogas, which reaches 57.6 million m³/day (source: Abiogás).
