GlobeSt.com: How much of your portfolio is green?

Schwartz: If you define green as being more energy-efficient, as reducing greenhouse gas emissions beyond what is normal, I would argue that 100% of our development would classify as sustainable. In every country where we develop--all 22--we build to a higher standard than the average building in that market, and with that comes significantly higher energy efficiency. An airtight building with less leakage of heating or air conditioning is an easy way to save massive amounts of energy and, of course, greenhouse gas emissions. It's a little more expensive to build a higher-quality building, but we are building a long-term sustainability business on a global platform. That has to start with a more sustainable footprint, even before you get to the other things that people think are a lot sexier and more exotic--solar panels or wind turbines---all of which we do.
