What is Green500?

Green500 aims to enlist London’s top 500 organisations and mentor them through their carbon reduction commitments.


How does Green500 actually work?

Green500 members receive an assessment of their London carbon footprint by a designated carbon mentor.  An individual ‘Action Plan’ will then be tailored to address each company’s specific carbon needs.  This offers estimated financial and carbon savings for energy, waste, water and transport, as well as information on an expected payback period for each action successfully implemented.
