Pounds of CO₂ / 1,000 RTMs* Environmental Stewardship Reducing Our Emissions Over the last decade, BNSF has upgraded about 40 percent of our locomotive fleet to more energy-efficient technologies, helping us make great strides in increasing fuel efficiency and decreasing CO2 and particulate emissions. We have also improved fuel efficiency through changes in operations and maintenance practices.

BNSF Recycling Materials Major recycling efforts further reduce BNSF's environmental impact. In 2016, BNSF recycled approximately: 1.1M 1.4M railroad ties pounds of batteries 4.3M gallons of lube oil 18
