Union Pacific Railroad Participating in More Than 100 Earth Day Events in Nearly 70 Communities

For Immediate Release:

Omaha, Neb., April 15, 2010 - Union Pacific Railroad will participate in

more than 100 Earth Day events in nearly 70 communities this month. The

events will include an array of activities such as tree plantings,

beautification projects, hands-on school activities, shoe recycling

programs and the annual Earth Day Fair at the Union Pacific Center in

Omaha.

I am extremely proud of the way so many of our employees are committed

to environmental stewardship, said Bob Grimaila, Union Pacific vice

president - Safety, Security and Environment. Our goal is for every

employee to play a role in reducing Union Pacific's environmental

footprint as well as their individual environmental impact.

Among Union Pacific's Earth Day plans are the following.

* In metropolitan St. Louis, tree plantings, essay contests and

kid-friendly environmental presentations are some of the activities

Union Pacific employees will shepherd at schools in Dupo and East St.

Louis, Illinois, as well as St. Louis and De Soto, Missouri.

* In Colton, California, employee volunteers will work to clean up

the Mary Vagle Nature Center, a nature trail preservation.

* In Fort Worth, Texas, employees will join local volunteers in

cleanup of two neighborhood parks and a community center.

* In suburban Chicago, Union Pacific employees will help clean up

a stretch of the Illinois Prairie Path, a 62-mile multi-use limestone

trail.

* In Cheyenne, Wyoming, Union Pacific will collaborate with the

city, the Wyoming Department of Environmental Quality, a local Boy Scout

troop and other organizations on the Ames Avenue beautification project

that will result in planting native grasses, trees and shrubs.

* In Tucson, Union Pacific will donate materials to homes being

constructed by the local Habitat for Humanity chapter.

* In Houston, Union Pacific volunteers will present special

environmental lessons to students at E.O. Smith School.

* In South St. Paul, Minnesota, employee volunteers will work with

other community organizations to help with the River Bike Path cleanup.

Railroads Reduce America's Emissions

Many of the communities throughout Union Pacific's 23-state system can

trace their origins directly to a Union Pacific depot. Today, railroads

are the freight transportation answer to reducing America's emissions

and related greenhouse gas emissions.

In addition to delivering the goods American families and businesses use

every day, Union Pacific is playing a central role in supporting the

renewable energy industry. The railroad delivers materials energy

customers need to expand America's natural gas pipeline network,

generate more electricity from wind and support the growing demand for

ethanol under the Renewable Fuel Standard.

Union Pacific has the cleanest locomotive fleet in the industry with

more than 75 percent certified under existing EPA Tier 0, Tier 1 and

Tier 2 emissions standards. Union Pacific pioneered the Genset switching

locomotive, which reduces nitrogen oxide emissions by 80 percent,

particulate matter by as much as 90 percent and reduces fuel use by 37

percent compared to older switching locomotives.

Reducing fuel consumption drives a smaller emissions profile. Union

Pacific's continued work to improve fuel efficiency -- which is 20

percent better since 1998 -- and reduce emissions is wide ranging.

Examples include:

* Union Pacific's Fuel Masters Unlimited program that rewards

locomotive engineers for efficiently operating trains.

* Fuel conservation speed programs that limit the use of

higher-throttle notches on trains.

* A comprehensive process to reduce unnecessary locomotive idling

time.

* Implementing technology such as distributed power, GPS systems,

virtual simulation training and ultrasonic wheel inspection of rail cars

that contributes to creating a safer and more fluid rail network.

Freight railroads help reduce highway congestion which improves transit

times, increases driver safety and reduces truck emissions. For example,

a single Union Pacific double-stack train can take as many as 300 trucks

off the highways.

Innovative thinking, technology development and the commitment of Union

Pacific's people have been hallmarks of the railroad's nearly 150 years

of service to America and are at the core of making Union Pacific one of

the safest, most fuel-efficient and environmentally responsible modes of

freight transportation.
