2008年8月20日，甲与乙签订了一份房屋租赁合同。合同约定：甲将自有住房一套出租给乙居住，每月租金2000元，按月收租，租期二年。合同签订后，双方到房地产管理部门办理了登记手续。当日，乙交付了押金和租金后入住。此后，乙每月按期交租。2009年2月，甲因欠丙60万元，便将该房屋抵押给丙，双方订立了抵押合同，但未办理抵押登记手续，合同约定：如甲不能在2009年6月底还债，该房屋归丙所有。后甲在2009年6月底未能还债，丙于是在2009年7月起开始主张实现其抵押权，要求乙向其缴纳租金，乙以自己与甲签订房屋租赁合同，丙无权收取租金为由拒绝。此后，即从2009年7月至2010年5月，无论甲、丙怎样催促，乙既拒绝向甲交租，也不向丙交租，遂甲决定终止租赁合同。 问题：

Consumers are being confused and misled by the hodge-podge of environmental claims made by household products, according to a "green labeling" study published by Consumers International Friday.

Among the report’s more outrageous findings-a German fertilizer described itself as "earthworm friendly" a brand of flour said it was "non-polluting" and a British toilet paper claimed to be "environmentally friendlier".

The study was written and researched by Britain’s National Consumer Council (NCC) for lobby group Consumer International. It was funded by the German and Dutch governments and the European Commission.

"While many good and useful claims are being made, it is clear there is a long way to go in ensuring shoppers are adequately informed about the environmental impact of products they buy." said Consumers International director Anna Fielder.

The 10-country study surveyed product packaging in Britain, Western Europe, Scandinavia and the United States. It found that products sold in Germany and the United Kingdom made the most environmental claims on average.

The report focused on claims made by specific products, such as detergent insect sprays and by some garden products. It did not test the claims, but compared them to labeling guidelines set by the International Standards Organization (ISO) in September, 1999.

Researchers documented claims of environmental friendliness made by about 2,000 products and found many too vague or too misleading to meet ISO standards.

"Many products had specially-designed labels to make them seem environmentally friendly, but in fact many of these symbols mean nothing." said report researcher Philip Page.

"Laundry detergents made the most number of claims with 158. Household cleaners were second with 145 separate claims, while paints were third on our list with 73. The high numbers show how very confusing it must be for consumers to sort the true from the misleading." he said.

The ISO labeling standards ban vague or misleading claims on product packaging, because terms such as "environmentally friendly" and "non-polluting" can not be verified. "What we are now pushing for is to have multinational corporations meet the standards set by the ISO." said Page.

It can be inferred from the passage that the lobby group Consumer International wants to（）.

A. make product labeling satisfy ISO requirements

B. see all household products meet environmental standards

C. warn consumers of the danger of so-called green products

D. verify the efforts of non-polluting products
