Omnitrans巴士將超過100萬英里處CNG英里的旅行，2013年4月
美國公共交通協(xié)會（APTA）報告，超過35％的美國公共運輸車輛使用替代燃料或混合動力技術(shù)，2011年1月1日。這是一個鮮明的對比，使用替代燃料的汽車，在2010年的1.3％，根據(jù)能源情報署（EIA）的年度展望。操作上天然氣的車輛都走在了前列。
“公共交通是環(huán)保高效的車輛，一路領(lǐng)先”，“亞太貿(mào)易協(xié)定”的總裁兼首席執(zhí)行官Michael Melaniphy說。“公共交通車輛試驗場的環(huán)保技術(shù)可能在某一天成為國家的汽車車隊的一部分。”
“亞太貿(mào)易協(xié)定”的統(tǒng)計，2011年初顯示，18.6％的美國公交車使用壓縮天然氣（CNG），液化天然氣（LNG）和混合。近9％（8.8％）的公共交通巴士，混合動力車和生物柴油近8％（7.9％）的公共交通巴士使用。
“今天的現(xiàn)代公交車是越來越多的混合燃料是良好的環(huán)境是由”亞太貿(mào)易協(xié)定“，說：”主席花都卡斯蒂略。“公共交通行業(yè)是一個綠色產(chǎn)業(yè)和致力于改善環(huán)境。”

“亞太貿(mào)易協(xié)定”指出，美國使用公共交通每年節(jié)省37萬噸的碳排放。此外，由于公共交通使用在美國每年可以節(jié)省470億加侖的汽油，公共交通乘客做自己的一部分，以幫助我們的國家能源獨立，根據(jù)“亞太貿(mào)易協(xié)定”。
下面列出的是CNG燃料車隊在全國范圍內(nèi)小型，中型和大型系統(tǒng)的多樣性的例子：
- 達(dá)拉斯，德克薩斯州 - DART的CNG新的艦隊40英尺巴士車隊開始服務(wù)2013年1月28到2015年將取代該機(jī)構(gòu)的混合柴油和液化天然氣公交車。2015年底，該機(jī)構(gòu)的年度燃料成本將減少近三分之二。DART將每周五個新巴士投入服務(wù)，以取代現(xiàn)有的機(jī)隊。
- 洛杉磯，加利福尼亞 - LA地鐵經(jīng)營2,200 CNG汽車在美國最大的CNG車隊。洛杉磯地鐵也買在美國的所有公交車的15％。
- 加利福尼亞州San Bernardino - Omnitrans所有CNG艦隊將超過100萬英里處，2013年4月。第一Omnitrans CNG公交車在1997年開始購買柴油，壓縮天然氣的過渡，并走在了前列，采用清潔燃料技術(shù)幾年前區(qū)域的空氣質(zhì)量法規(guī)授權(quán)開關(guān)。
- 賓夕法尼亞州立學(xué)院 - 中心區(qū)交通管理局的整個艦隊上運行的CNG。它是第一個在東海岸運輸機(jī)構(gòu)將其整個柴油車完全替代燃料運行。
- 亞利桑那州鳳凰城 - 谷地鐵站的巴士車隊使用CNG和生物柴油燃料，以及電動混合動力公交車。
- 薩利姆，OR - 薩利姆-科澤爾運輸?shù)能囮犛?4輛CNG公交車和30個生物柴油巴士。在2010年，過境區(qū)購買了第一氣/電混合總線。

Omnitrans buses will surpass the 100 million mile mark in CNG miles traveled, April 2013
The American Public Transportation Association (APTA) reports more than 35 percent of U.S. public transportation buses use alternative fuels or hybrid technology, as of January 1, 2011. This is a striking contrast to the 1.3 percent of automobiles that used alternative-fuels in 2010, according to the Energy Information Administration’s (EIA) Annual Outlook. Vehicles operating on natural gas are at the forefront.
“Public transportation is leading the way with environmentally efficient vehicles,” said APTA President and CEO Michael Melaniphy. “The public transit vehicle fleet is the proving ground for environmental technology that may some day become a part of the nation’s automobile fleet.”
APTA statistics for early 2011 show that 18.6 percent of U.S. transit buses used compressed natural gas (CNG), liquefied natural gas (LNG) and blends. Almost 9 percent (8.8%) of public transit buses were hybrids and nearly 8 percent (7.9%) of public transit buses used biodiesel.
“Today’s modern public transit bus is increasingly either a hybrid or is powered by fuels that are good for the environment,” said APTA Chair Flora Castillo. “The public transportation industry is a green industry and is committed to improving the environment.”

APTA noted that U.S. public transportation use saves 37 million metric tons of carbon emission every year. Additionally, since public transit use in the United States saves 4.7 billion gallons of gasoline annually, public transit riders are doing their part to help our nation be energy independent, according to APTA.
Listed below are examples of the diversity of CNG-fuelled bus fleets across the country in small, mid-sized, and large systems:
- Dallas, TX – DART’s new fleet of CNG 40-foot buses fleet began service on January 28, 2013 and will replace the agency’s mix of diesel and liquefied natural gas buses by 2015. The agency’s annual fuel costs will be cut by nearly two-thirds by the end of 2015. DART is putting five new buses into service every week to replace the existing fleet.
- Los Angeles, CA – LA Metro operates the largest CNG fleet in the U.S. with 2,200 CNG vehicles. LA Metro also buys 15% of all transit buses in the United States.
- San Bernardino, CA – Omnitrans’ all CNG fleet will surpass the 100 million mile mark in April, 2013. Omnitrans first started to purchase CNG buses in 1997 and was at the forefront of the transition from diesel fuel to compressed natural gas, adopting the clean fuel technology years before regional air quality regulations mandated the switch.
- State College, PA – Centre Area Transportation Authority’s entire fleet runs on CNG. It was the first transit agency on the East Coast to convert its entire diesel fleet to one that operates entirely on alternative fuel.
- Phoenix, AZ – Valley Metro’s bus fleet uses CNG and biodiesel fuels, as well as electric-hybrid buses.
- Salem, OR – Salem-Keizer Transit’s fleet is made up of 34 CNG buses and 30 biodiesel buses. In 2010, the transit district purchased its first hybrid gas/electric bus.
