Taking a look at the week ahead for the footwear and apparel industry, here is a snapshot of just-style's latest news and insights agenda.

This week just-style will be covering two events that indicate where the future of sustainability reporting and sizing is headed.

Jochen Zeitz, CEO of Puma and chief sustainability officer of PPR is to present the company’s first Environmental Profit & Loss Account (EP&L) today (16 May). PPR says the analysis is the first of its kind in corporate reporting.

Also today, just-style will be meeting executives at Alvanon, which is launching a series of fit forms based on a new European women's and men's wear fit standard. 

Alvanon says the new EU Standard Forms are the result of thousands of 3D body scans of European men and women in the 20 to 40 year old age range.

Also this week, US retailers including Wal-Mart, Abercrombie & Fitch and Gap Inc are due to release their first quarter results, while sourcing giant Li & Fung will host its annual general meeting (AGM) in Hong Kong.

Reporting its full-year results in February, Wal-Mart continued to see its international operations drive growth as it recorded another quarter of declining sales in its US division.

The company, whose UK unit Asda has announced plans to take its George brand overseas today, is expected by analysts to report another domestic decline for Q1.

However, profits are forecast to rise once more, with Wal-Mart succeeding in keeping costs down and boosting international sales.
