  • Environmental performance - Bam Holding

    The emissions from asphalt production account for 17 per cent of BAM's total CO2 emissions. In 2020, CO2 emissions were six per cent lower than in 2019. Even though more asphalt was produced in 2020, ongoing efforts to improve energy efficiency and the use of less carbon-intensive fuels led to a reduction of CO2 emissions in asphalt plants.
