Protecting Our Blue PlanetȠ

We believe in the preservation of a Blue Planet... a cleaner, safer and healthier

world where people thrive – not just for today, but generations to come.

We are guardians of our environment and have a responsibility to regenerate our

planet with the materials we are entrusted to handle every day by driving

increased recycling, generating renewable energy and

helping our customers be more resourceful.

We must lead by example, working diligently to improve

our relationship with the environment and society

through decreased vehicle emissions, innovative

landfill technologies, use of renewable energy,

community engagement and employee growth

opportunities.

This is not a fleeting cause. It is the foundation

of our future, and the very heart of who we are as

we work every day to protect our Blue Planet.

A Republic Services Perspective

• Why CNG?• Where Does CNG Make Sense?

• What is the Impact?CNG Fleet Photos

1. It’s the right thing to do – and it’s environmentally

responsible

2. It’s cleaner – emissions are lower and increasingly alternative

fuels are mandated

3. It’s local – natural gas is abundantly available from North

American sources

4. It’s cheaper – current natural gas costs are lower than diesel

5. It’s quieter – customers like less noise

Why CNG?

Where Does CNG Make Sense?

A suitable site

(e.g. access to gas pipeline,

adequate space, ease of

permitting, etc.)

Natural Gas vs. Diesel (Forward Curves)

Despite updated EIA projections, the current spread between

diesel and natural gas continues to make economic sense.

Site Development Opportunity Matrix

Our primary focus continues to be sites with more than 50 trucks.

There are still significant numbers of site/truck candidates for CNG.

CNG Challenges

CNG conversion is not a one size fits all solution. Depending on site

characteristics, CNG may not be practical.
