Tier 4 is more than just emissions.
It’s about changing the world for the better.
- Tier 4 standards reduce emissions from a typical non-road diesel engine by up to two-thirds.
- Respiratory problems and disease caused by ozone and PM will decline – as will acid rain, crop damage and smog.
- By 2030, the EPA estimates that 12,000 deaths, 8,900 hospitalizations and one million lost work days will be prevented.
