轮胎实测显示：车队使用绿色轮胎最高可节省7%燃油消耗

· 朗盛与RheinEnergie公司轮胎实测证实“绿色轮胎”可以大幅减少油耗

· RheinEnergie第一步将为旗下130辆汽车配备“绿色轮胎”

· 城市交通情况下平均燃油消耗降低4.1%

· 测试结果经TÜV德国莱茵集团认证

· 测试为科隆智慧城市（SmartCity Cologne）计划的一部分

· 假如科隆所有车辆都使用“绿色轮胎”将能够减少1980万升燃油消耗并将二氧化碳排放降低近48,000 吨

科隆——全球领先的合成高性能橡胶生产商朗盛联合能源供应商RheinEnergie公司完成了轮胎实测，结果显示在城市交通情况下，“绿色轮胎”最多可节省7%的燃油消耗（平均减少约4.1%的燃油消耗），并且每年可使车队运营商节省数千欧元。欧盟轮胎标签体系中燃油效率“C”级以上的高性能轮胎的二氧化碳排放也比标准轮胎大幅下降。

朗盛集团管理董事会成员卢塞尔说：“经过这个长期的测试，我们证实了高性能轮胎在使用中不仅能为车队运营商，也能为个人大幅节省成本。此外，‘绿色轮胎’也为环境保护做出了重要贡献。”举例来说，如果所有在科隆的注册的442,013辆柴油和汽油车用滚动阻力更低的B级“绿色轮胎”替换F级的轮胎，每辆车平均行驶14,000公里，那么科隆一年将可能节省1980万升燃油消耗，并减少48,000吨二氧化碳排放量。这意味着使用“绿色轮胎”可抵消科隆市18,000多辆汽车的二氧化碳排放量。

另举一个例子充分展示使用“绿色轮胎”为车队运营商带来的经济利益：一个拥有650辆轿车或3.5吨以下小货车的车队用欧盟轮胎标签体系滚动阻力B级的轮胎替换F级的轮胎，假设每辆车行驶14,000公里，油价1.35欧元/升，那么车队一年可以节省近44,500欧元，二氧化碳排放将减少87吨。

RheinEnergie将开始使用“绿色轮胎”
RheinEnergie决定为其旗下的车辆配备“绿色轮胎”。第一步将为约130辆因正常轮胎磨损需要替换轮胎的车辆配备“绿色轮胎”。在“绿色轮胎”提供更多尺寸选择之后，其余车辆也将陆续替换。

“作为一个能源服务供应商，我们非常重视自己对于环境的责任，”RheinEnergie公司执行董事会成员Norbert Graefrath说。“我们非常高兴有这样一种便捷的方式可以为环保做出贡献。”首批130辆汽车使用“绿色轮胎”之后一年可以减少11吨二氧化碳排放。

TÜV 德国莱茵认证试验结果

TÜV德国莱茵集团是世界领先的独立技术服务机构，该集团监控并审核了朗盛和RheinEnergie整个试验过程，并记录和认证了所有试验结果。“TÜV德国莱茵集团监控的这个测试证实了即使是轻型车在城市交通环境中，使用绿色轮胎仍可以节省费用并对环境做出贡献，”TÜV德国莱茵集团管理董事会成员Juergen Brauckmann说道。

科隆智慧城市计划的试点项目

朗盛和RheinEnergie联合进行的轮胎实测是科隆智慧城市计划的一部分。该计划由RheinEnergie和科隆市在2012年提出。

科隆市气候保护司司长BarbaraMöhlendick博士说：“科隆希望通过智慧城市计划证明成功的商业发展和环境保护并非相互排斥。我坚信最先进的技术能够提供创新的解决方案，不仅解决紧迫的气候和环境保护问题，还包括城市规划问题。轮胎实测的成功就是一个很好的例子。”

科隆智慧城市计划提供了一个有关气候保护和能源革命各个项目的平台，任何个人、企业、协会和项目公司都可以参与进来，共同开发智能理念和开拓性技术，提升科隆的城市面貌。智慧城市计划中的积极分子们正利用这一平台，尝试各种技术和服务来应对气候变化带来的挑战，塑造未来生态友好的城市生活。

朗盛和RheinEnergie轮胎实测详情

在实验过程中，实验组监测了六辆RheinEnergie公司同样的车型在半年中的燃油消耗量，并比较了“绿色轮胎”和标准轮胎在燃油消耗方面的差距。实验的车辆重约2吨，在实验期间行驶在科隆市及周边地区，路线、司机、载重和加油条件完全一致。试验结束后，所有车辆总行程达37,000公里。

为确保实验结果有效性，此次试验分两个阶段进行。在前三个月中，第1组的三辆车配备了“绿色轮胎”（欧盟轮胎标签体系滚动阻力B级），而第2组的三辆车配备标准轮胎（欧盟轮胎标签体系滚动阻力F级）。在后三个月中，两组车辆的轮胎互换。结果表明，“绿色轮胎”最高可节省燃油消耗达6.96%，而二氧化碳排放量每万公里最多可降低155千克。

欧盟自2012年开始实施强制轮胎标签法

欧盟于2012年11月1日开始对新轮胎强制实施标签法。这一法规适用于所有车辆的轮胎，包括私家车和轻、重型商用车。在轮胎标签上，滚动阻力（即燃油消耗）划分为A级（低滚动阻力）到G级（高滚动阻力）。标签还显示关于轮胎湿抓地力（安全性）和滚动噪音量的信息。“绿色轮胎”在欧盟标签上的评级非常高。

朗盛车队计算器协助节省燃料

朗盛为车队定制了一个计算程序──“朗盛车队计算器”。这个程序可协助营运商有效减少车辆的燃油消耗并降低运营成本。这个计算程序让车队运营商能够计算车辆改用“绿色轮胎”后长期节省的燃料以及减少的二氧化碳排放。它还能提示在什么情况下值得作出这样的投资。

这个车队计算程序由朗盛与慕尼黑工业大学合作开发。只需登录http://flotte.green-mobility.de/en，进行简单注册，就可以免费使用。

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 Möhlendick, 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.
