輪胎實測顯示：車隊使用綠色輪胎最高可節省7%燃油消耗

· 朗盛與RheinEnergie公司輪胎實測證實“綠色輪胎”可以大幅減少油耗

· RheinEnergie第一步將為旗下130輛汽車配備“綠色輪胎”

· 城市交通情況下平均燃油消耗降低4.1%

· 測試結果經TüV德國萊茵集團認證

· 測試為科隆智慧城市（SmartCity Cologne）計劃的一部分

· 假如科隆所有車輛都使用“綠色輪胎”將能夠減少1980萬升燃油消耗并將二氧化碳排放降低近48,000 噸

科隆——全球領先的合成高性能橡膠生產商朗盛聯合能源供應商RheinEnergie公司完成了輪胎實測，結果顯示在城市交通情況下，“綠色輪胎”最多可節省7%的燃油消耗（平均減少約4.1%的燃油消耗），并且每年可使車隊運營商節省數千歐元。歐盟輪胎標簽體系中燃油效率“C”級以上的高性能輪胎的二氧化碳排放也比標準輪胎大幅下降。

朗盛集團管理董事會成員盧塞爾說：“經過這個長期的測試，我們證實了高性能輪胎在使用中不僅能為車隊運營商，也能為個人大幅節省成本。此外，‘綠色輪胎’也為環境保護做出了重要貢獻。”舉例來說，如果所有在科隆的注冊的442,013輛柴油和汽油車用滾動阻力更低的B級“綠色輪胎”替換F級的輪胎，每輛車平均行駛14,000公里，那么科隆一年將可能節省1980萬升燃油消耗，并減少48,000噸二氧化碳排放量。這意味著使用“綠色輪胎”可抵消科隆市18,000多輛汽車的二氧化碳排放量。

另舉一個例子充分展示使用“綠色輪胎”為車隊運營商帶來的經濟利益：一個擁有650輛轎車或3.5噸以下小貨車的車隊用歐盟輪胎標簽體系滾動阻力B級的輪胎替換F級的輪胎，假設每輛車行駛14,000公里，油價1.35歐元/升，那么車隊一年可以節省近44,500歐元，二氧化碳排放將減少87噸。

RheinEnergie將開始使用“綠色輪胎”
RheinEnergie決定為其旗下的車輛配備“綠色輪胎”。第一步將為約130輛因正常輪胎磨損需要替換輪胎的車輛配備“綠色輪胎”。在“綠色輪胎”提供更多尺寸選擇之后，其余車輛也將陸續替換。

“作為一個能源服務供應商，我們非常重視自己對于環境的責任，”RheinEnergie公司執行董事會成員Norbert Graefrath說。“我們非常高興有這樣一種便捷的方式可以為環保做出貢獻。”首批130輛汽車使用“綠色輪胎”之后一年可以減少11噸二氧化碳排放。

TüV 德國萊茵認證試驗結果

TüV德國萊茵集團是世界領先的獨立技術服務機構，該集團監控并審核了朗盛和RheinEnergie整個試驗過程，并記錄和認證了所有試驗結果。“TüV德國萊茵集團監控的這個測試證實了即使是輕型車在城市交通環境中，使用綠色輪胎仍可以節省費用并對環境做出貢獻，”TüV德國萊茵集團管理董事會成員Juergen Brauckmann說道。

科隆智慧城市計劃的試點項目

朗盛和RheinEnergie聯合進行的輪胎實測是科隆智慧城市計劃的一部分。該計劃由RheinEnergie和科隆市在2012年提出。

科隆市氣候保護司司長BarbaraM?hlendick博士說：“科隆希望通過智慧城市計劃證明成功的商業發展和環境保護并非相互排斥。我堅信最先進的技術能夠提供創新的解決方案，不僅解決緊迫的氣候和環境保護問題，還包括城市規劃問題。輪胎實測的成功就是一個很好的例子。”

科隆智慧城市計劃提供了一個有關氣候保護和能源革命各個項目的平臺，任何個人、企業、協會和項目公司都可以參與進來，共同開發智能理念和開拓性技術，提升科隆的城市面貌。智慧城市計劃中的積極分子們正利用這一平臺，嘗試各種技術和服務來應對氣候變化帶來的挑戰，塑造未來生態友好的城市生活。

朗盛和RheinEnergie輪胎實測詳情

在實驗過程中，實驗組監測了六輛RheinEnergie公司同樣的車型在半年中的燃油消耗量，并比較了“綠色輪胎”和標準輪胎在燃油消耗方面的差距。實驗的車輛重約2噸，在實驗期間行駛在科隆市及周邊地區，路線、司機、載重和加油條件完全一致。試驗結束后，所有車輛總行程達37,000公里。

為確保實驗結果有效性，此次試驗分兩個階段進行。在前三個月中，第1組的三輛車配備了“綠色輪胎”（歐盟輪胎標簽體系滾動阻力B級），而第2組的三輛車配備標準輪胎（歐盟輪胎標簽體系滾動阻力F級）。在后三個月中，兩組車輛的輪胎互換。結果表明，“綠色輪胎”最高可節省燃油消耗達6.96%，而二氧化碳排放量每萬公里最多可降低155千克。

歐盟自2012年開始實施強制輪胎標簽法

歐盟于2012年11月1日開始對新輪胎強制實施標簽法。這一法規適用于所有車輛的輪胎，包括私家車和輕、重型商用車。在輪胎標簽上，滾動阻力（即燃油消耗）劃分為A級（低滾動阻力）到G級（高滾動阻力）。標簽還顯示關于輪胎濕抓地力（安全性）和滾動噪音量的信息。“綠色輪胎”在歐盟標簽上的評級非常高。

朗盛車隊計算器協助節省燃料

朗盛為車隊定制了一個計算程序──“朗盛車隊計算器”。這個程序可協助營運商有效減少車輛的燃油消耗并降低運營成本。這個計算程序讓車隊運營商能夠計算車輛改用“綠色輪胎”后長期節省的燃料以及減少的二氧化碳排放。它還能提示在什么情況下值得作出這樣的投資。

這個車隊計算程序由朗盛與慕尼黑工業大學合作開發。只需登錄http://flotte.green-mobility.de/en，進行簡單注冊，就可以免費使用。

Practical test: vehicle fleet operators save up to 7 percent in fuel using “green tires”

·Joint LANXESS and RheinEnergie practical tire test confirms considerable fuel savings

·As a first step, RheinEnergie is fitting 130 vehicles successively with “green tires”

·Average fuel saving of 4.1 percent in urban traffic

·Results verified by TüV Rheinland

·Practical test part of the SmartCity Cologne project

·Running every car in Cologne on “green tires” would save approximately 19.8 million liters of fuel and reduce CO2 emissions by almost 48,000 metric tons

Cologne – “Green tires” reduce the fuel consumption of vehicles by as much as 7 percent in urban traffic (around 4.1 percent on average) and can save fleet operators thousands of euros every year. These high-performance tires – graded “C” or above for fuel efficiency on the EU tire label – also significantly reduce the CO2 emissions of vehicles compared to standard tires. These are the results of a practical tire test jointly conducted by LANXESS, the world’s leading manufacturer of synthetic high-performance rubbers for the tire industry, and energy provider RheinEnergie.

“With this long-term test, we have now also shown in practice that high-performance tires hold great savings potential for fleet operators and also for individuals. ‘Green tires’ not only cut costs, they also make an important contribution to protecting the environment,” says Rainier van Roessel, member of the LANXESS AG Board of Management. For example, if all of the 442,013 diesel and gasoline passenger cars registered in Cologne ran on “green tires” of rolling resistance class B rather than F, then it would be possible to save some 19.8 million liters of fuel and reduce CO2 emissions by almost 48,000 metric tons a year, based on an average mileage of 14,000 kilometers. The use of “green tires” alone could therefore compensate for the CO2 emissions of more than 18,000 cars on Cologne’s roads.

The full extent of the economic benefits of switching to “green tires” for fleet operators can be seen in another example: a fleet with a total of 650 cars or vans of up to 3.5 metric tons currently running on tires with a rolling resistance rating of F on the EU label could save almost EUR 44,500 a year in fuel costs just by switching to B-rated tires – assuming a distance of 14,000 kilometers per vehicle and a diesel price of EUR 1.35/liter. The CO2 reductions would amount to almost 87 metric tons per year.

RheinEnergie uses “green tires”

RheinEnergie has therefore decided to successively switch its vehicle fleet over to “green tires”. The first step will be to refit around 130 vehicles as part of the usual tire replacement schedule resulting from wear. Others are to follow once “green tires” are also available in different sizes.

“As an energy service provider and supplier we take our responsibility for the environment very seriously,” says RheinEnergie Executive Board member Norbert Graefrath. “We are delighted to find such an expedient and convenient way of making a contribution to environmental protection.” Already by refitting the first 130 vehicles it will be possible to cut CO2 emissions by a good 11 metric tons a year.

TüV Rheinland verifies test results

TüV Rheinland monitored and verified the practical tire test carried out by LANXESS and RheinEnergie as an independent authority and also documented all the results. “The long-term test monitored by TüV Rheinland confirms that it makes economic and environmental sense to use ‘green tires’ even on small vehicles used in urban traffic,” explains Jürgen Braukmann, member of the Group Executive Council of TüV Rheinland responsible for mobility.

Pilot project as part of SmartCity Cologne

The LANXESS and RheinEnergie joint practical tire test is part of the SmartCity Cologne project, which was launched by RheinEnergie and the City of Cologne in 2012.

“Through the SmartCity initiative Cologne is looking to demonstrate that successful commercial development and the goals of environmental protection are not mutually exclusive,” explains Dr. Barbara M?hlendick, climate protection coordinator of the City of Cologne. “I am firmly convinced that state-of-the-art technologies can offer innovative approaches for solving not only pressing climate and environmental protection problems but also urban planning issues. The success of the practical tire test is a perfect example.”

SmartCity Cologne is a platform for various projects relating to climate protection and the energy revolution. Anyone can take part – private individuals, companies, associations and initiatives. Together, they develop intelligent ideas and pioneering technologies that make Cologne a better place. The key players are using SmartCity to respond to the challenges posed by climate change. As part of the project, technologies and services are being tried out that will shape eco-friendly urban living in the future.

Details of the LANXESS and RheinEnergie practical tire test

Over a period of half a year, the fuel consumption of six identical RheinEnergie utility vehicles was examined under real conditions. The performance for both “green tires” and standard tires was compared to establish the potential savings. Weighing approximately two metric tons, the vehicles covered similar areas in the City of Cologne and the surrounding area during the test period. Driver, loaded weight and refueling procedures were identical for the vehicles. Over the length of the trial, all six vehicles covered a total distance of approximately 37,000 kilometers.

To achieve valid results, the half-yearly test was conducted in two phases. During the first three months, the three vehicles in group 1 were fitted with “green tires” (rolling resistance class B on the EU tire label), while the other three, in group 2, had standard tires (rolling resistance class F on the EU tire label). This was reversed in the second phase. The results showed that the maximum fuel saving amounted to 6.96 percent and CO2 emissions dropped by up to 155 kilograms per 10,000 kilometers.

Compulsory EU labeling since 2012

Compulsory labeling of new tires with the EU tire label came into force on November 1, 2012. This applies to tires for both private cars and light and heavy commercial vehicles. The label grades the rolling resistance (i.e. fuel consumption) of a model on a scale of A (low) to G (high). It also provides buyers with information about wet grip (safety) and the rolling noise volume. “Green tires” attain particularly good marks on the EU label.

LANXESS calculators help to save fuel

Specialty chemicals company LANXESS also provides a specially designed calculation program for fleets, the “LANXESS Vehicle Fleet Calculator”. This helps operators efficiently reduce their vehicles’ fuel consumption and lower operating costs. It enables fleet operators to calculate for themselves how much fuel they could save in the long term by switching their vehicles to “green tires.” The program also shows the point from which it is worthwhile making that kind of investment and the reduction in fleet CO2 emissions. LANXESS developed the calculator in collaboration with the Technical University of Munich. The full program is available free of charge online, requiring only a brief registration process, at http://flotte.green-mobility.de/en/.

LANXESS is a leading specialty chemicals company with sales of EUR 8.0 billion in 2014 and about 16,600 employees in 29 countries. The company is currently represented at 52 production sites worldwide. The core business of LANXESS is the development, manufacturing and marketing of plastics, rubber, intermediates and specialty chemicals. LANXESS is a member of the leading sustainability indices Dow Jones Sustainability Index (DJSI World and DJSI Europe) and FTSE4Good.
