Transcript of CSR with CCTA

Chittenden County Transporation Authority
Sustainability Through Alternative Transportation
by Becky Cohen Mission Statement The mission of CCTA is to “promote and operate safe, convenient, accessible, innovative and sustainable public transportation services in the Chittenden County region that reduce congestion and pollution, encourage transit oriented development and enhance the quality of life for all.”

CCTA has a section on their website devoted to their “Environmental Commitment.”

This section is about the use of 2007 Emissions Standard BioDiesel buses, and the benefits of BioDiesel.

It also states CCTA’s commitment to operate with the cleanest technology available, as funding allows, and to work to “pursue environmental responsibility through various conservation efforts.”

Two conservation efforts that are listed include recycling oil and antifreeze.
BioDiesel Problems with BioDiesel Alternatives BioDiesel is a cleaner-burning diesel fuel made from so called natural and renewable sources such as vegetable oils.

CCTA uses a blend of 20 percent by volume biodiesel with
80% by volume petroleum diesel

The 2007 Emissions Standards Buses emit significantly less emissions that 2006 Emissions Standards Buses

Chris Cole, General Manager, stated that the supply chain of BioDiesel and the quality of the fuel is continually called into question, and whether or not it is truly a good alternative.
Disadvantages of using biodiesel produced from agricultural crops involve additional land use, as land area is taken up and various agricultural inputs with their environmental effects are inevitable.

As Cole stated, the supply chain of BioDiesel is questionable, and because of the difficulty in verifying the quality of the BioDiesel, CCTA does not do so.

This is one key aspect that needs to be further investigated. Although BioDiesel is a so called “sustainable” fuel, land that was previously used to grow crops for food now is used to grow crops for fuel. In addition, significant amounts of petroleum and petroleum based products are used when growing crops- it almost negates the benefits of using BioDiesel

Quality Control is also an issue, and CCTA needs to find a secure supply chain that they feel confident in to provide them with the highest quality of BioDiesel
Currently, CCTA uses BioDiesel as an alternative to a 100% petroleum based fuel

However, they should be looking into electric powered engines, and hybrid buses, as well as converting certain buses to run on 100% used vegetable oil if they want to be a truly sustainable company

In addition, they need to look at the supply chain outside of BioDiesel and where their buses are sourced from and the environmental effects of building a bus
