In 2011, global demand for platinum and palladium inautocatalyst applications increased by 4.4% and 5.2%respectively. These gains lifted autocatalyst consumptionof platinum to a total of 3.02M ounces (94.0 tonnes) lastyear, with palladium reaching a ten year high of 5.53M ounces (172.0 tonnes). While palladium has staged animpressive recovery since the auto industry recession of2009 (with demand now well in excess of pre-recession levels), platinum’s situation remains problematic. Although demand for platinum has improved considerably from its low of 2.52M ounces (78.3 tonnes) in 2009, last year’s total of 3.0M ounces (94.0 tonnes) remains well adrift of the record high 4.01M ounces (124.8 tonnes) which platinum enjoyed in 2007 prior to the economic downturn.
2011年，全球铂、钯催化剂需求分别增加了4.4%和5.2%，使去年铂催化剂总消耗量达到302万盎司（约94吨），而钯催化剂消耗量达到553万盎司（172吨），创10年历史新高。自2009年汽车行业衰退以来，钯催化剂的需求有了显著回升（目前需求量已超过经济衰退前的水平），但铂催化剂的状况仍不容乐观。和2009年252万盎司（78.3吨）铂催化剂总消耗量相比，去年300万盎司的总消耗量确实有了大幅上涨，但与2007年经济危机之前历史最高的401万盎司（124.8吨）相比，仍存在较大差距。
In the main, platinum’s difficulties in autocatalyst can be ascribed to two main factors, both of which relate to light vehicle applications and in particular, light duty diesels. First, notwithstanding the growing importance of the heavy duty sector, light duty diesels account for two-thirds of global platinum autocatalyst demand, with the vast majority of this being concentrated in Europe where diesel’s share of light vehicle production is disproportionately large. While light diesel production globally has re-attained pre-recession levels, this is not entirely the case in Europe where leading edge emission standards and generally higher PGM loadings apply. Meanwhile, diesel’s share of light vehicle production elsewhere in the world remains moderate and although production gains have occurred in recent years, these have been concentrated in areas where emissions regulation is weaker, with correspondingly lower PGM loadings.

总体而言，造成铂催化剂市场困境的原因可以归结为两个方面，并且这两个方面均与轻型汽车应用，尤其是轻型柴油汽车有关。首先，虽然重型汽车的重要性日益凸显，但轻型柴油汽车却占全球铂催化剂需求的三分之二，其中大部分集中在欧洲。欧洲轻型柴油汽车在轻型汽车产量中的比例偏高，且超出正常比例。虽然全球轻型柴油汽车产量已经恢复到经济危机之前的水平，但欧洲市场却并未完全恢复，因为欧洲采取了最为严格的排放标准和更高的PMG载量要求。此外，世界其他地区柴油汽车在轻型车产量中的比例保持稳定，虽然近几年柴油汽车产量增加，但增长主要集中在排放监管较为薄弱，PGM载量相对较低的地区。
