Engine design also incorporates technology for emission reduction and after treatment where necessary as well as allowing for the potential future use of biofuels for Caterpillar products.
While not specifically part of the environmental benefits, the product design also incorporates safety features that increase the safety, health and welfare of operators while protecting others working in close proximity. Caterpillar is fully committed to the United States Climate Action Partnership and is currently Number 1 in the Dow Jones Sustainability Index (2006).
