Adessy’s Definitions:

Investment = capital, energy, time, knowledge, networks etc.

Social return = a multitude of (indirect) non-financial gains that have social and environmental value. To give a flavour of social return, measures can relate to impact on recipients; employee engagement; improved opportunities and quality of life; new knowledge, thinking and ways of doing; open dialogue; new partnerships or engagement... and so much more.

Innovation return = a multitude of (indirect) non-financial gains that can lead to transformation - new products, services, processes or new markets; enhancing opportunities - such as changing composition of products, services or processes; or on an individual level - rethinking the ways you do things on a daily b asis, creative thinking, being curious and experimenting, realising ambitions... etc.

How We Do It

We believe a better world is possible and we want to make it happen.

With our highly personal approach, we work with organisations and individuals from around the world who are engaged thinkers and / or doers of sustainable and wider Corporate Social Responsibility (CSR) or philanthropic activities.

Adessy tailors Catalyst packages, Consulting and Advisory and Capacity Building services to meet client’s needs and budget.

Adessy incorporates a pragmatic understanding of social, environmental, economic and human ethical principles. This allows us to focus on generating positive and sustainable outcomes that drive longer-term value, greater profit potential and facilitate positive change.

Typically, our clients benefit from our support with, for example:

  • Communicating activities and adding value to clients, investors, suppliers, and end users
  • Refining strategy or generating new, innovative sustainability concepts and/or ways of executing those
  • Feasibility or research studies
  • Measuring the impact of activities already in place
  • Developing leadership champions who blend purpose, strategy, collaboration and engagement to effect systemic change and sustainable prosperity
Adessy works from the premise that positive change and business outcomes are mutually reinforcing.
