Off-road applications, which include handheld equipment, are among the areas that are difficult to fully electrify for a variety of reasons. STIHL products, especially handheld power tools, are used worldwide to shape and maintain the environment and are daily assistants in forestry and construction, operated under very demanding environmental conditions. In the power equipment sector, as elsewhere, the shift from petrol to battery-powered products is already well underway, especially for consumer applications. However, for professional power tool users who demand the highest levels of power and energy density from their equipment, internal combustion engines will continue to be essential. Biofuels and RFNBOs possess the potential to be green alternatives, especially for this group of users. STIHL has already taken the first steps towards sustainable fuels with the market launches of MotoMix Eco and MotoMix Eco 20 containing a 20% biofuel content in 2025. Like the fully fossil MotoMix, Eco 20 is a premium alkylate fuel, meeting the requirements of the EN 17867 standard. With MotoMix Eco 20, an overall CO2 reduction of at least 25% compared to a fully fossil gasoline can be achieved. The continuous optimization of engine technology and its overall system, including cutting tools (saw chain, cutting wheel and blades), is another important component. Hence, the combination of our new, more efficient combustion technology with our sustainable MotoMix Eco 20 fuel, results in even higher CO2 reductions. The right choice of powertrain and tool, and the effective use of our products by the user, are the final building blocks for the most sustainable use of our equipment.
