The United States is responsible for 20% of the world’s carbon dioxide emissions -- and nearly half of that pollution comes from heating and maintaining our homes and buildings. As we reach for clean energy solutions to reduce our carbon footprint, we can’t ignore one of the cheapest and most effective ways to reduce our energy usage and our greenhouse gas emissions: energy-efficiency.

This month, the Ceres Sustainability Podcast speaks with Lauralee Martin, CFO of Jones Lang LaSalle, a global real estate services provider that operates and manages 1.4 billion square feet of commercial building space in more than 60 countries. Martin reveals how Jones Lang LaSalle is unlocking the power of energy efficiency to reduce energy use in commercial buildings and save money in the process.
