About

Corporate Sustainability Strategies (CSS) is an independent commercial real estate sustainability consulting firm, passionate about results.  Services are client-centric, centered on driving enhanced financial returns by designing and implementing cost effective sustainability strategies.

We provide expert consulting services centered on driving investor returns by designing and implementing cost effective and value creating sustainability strategies. CSS can support an existing program that is not maximizing potential or create one based on a proven model with a strategic focus.

Companies may have dipped their toe in the water of sustainability and have achieved an ENERGY STAR Label or perhaps even LEED certification. These are great tactical actions and provide advantages. However, Corporate Sustainability Strategies takes sustainability to the next level by developing an over-arching strategy that integrates sustainability into the way organizations do business.

A well-defined and established Sustainability program, as a fully embedded part of its overall business model, can have a meaningful impact on:

  • Bottom Line Performance
  • Brand Enhancement
  • Tenant Engagement, Attraction, Retention
  • Operating Margins
  • Investor Engagement, Attraction, Retention
  • Integrated Governance and Leadership
  • Value Creation
