Rail is the most energy efficient method of moving freight. No land transportation mode can outperform rail for the hauling of large volumes of high-density freight over long distances. But there is more that can be done. At CN, we believe the single best way railroads can positively impact the environment is by continuously improving the efficiency of their operations to reduce their carbon footprint and by minimizing the impact of their activities wherever possible.

CN's commitment to the reduction of air pollutants, including greenhouse gas emissions, takes place on several levels, from the unique way we operate the railroad through Precision Railroading to the adoption of a number of programs that advance railroad efficiency and promote emissions reduction.
