Invesco PowerShares is making a name for itself as the number one provider of niche ETF’s and last week it launched another green ETF, this time in the transportation sector.  The PowerShares Global Progressive Transporation Portfolio ETF (PTRP) is a diversified way to play the transition toward cleaner, less costly and more efficient means of transportation. It’s based on the Wilder Nasdaq OMX Global Energy Efficient Transport Index (which has performed remarkably well in a tough  trading environment here in 2008 – up nearly 17% YTD through June 30) and includes companies that:

- improve energy efficiency
- reduce fuel costs
- harness renewable energy
- enrich energy conservation
- upgrade information systems

The fund is well diversified with no single holding more than 4% and along with green companies such as Clean Energy Fuels (CLNE) and Fuel Systems Solutions (FSYS) also includes shipping and rail companies.  Strangely enough, the largest holding is a Mexican airport operator..
