For approximately the last 30 years, I have worked within and with organizations to help them to address the challenges presented by climate change and sustainability. Frustrated by the unnecessary complexity in these areas, my mission is to simplify the complex for the greater environmental benefit and provide cost effective solutions to help organisations on their sustainability journey. My understanding of regulations, their direction and evolution has enabled me to simplify this complexity and influence company strategies to ensure the risks presented are managed and the potential of new opportunities realized. My knowledge across a broad spectrum of sustainability regulations and carbon markets of the UNFCCC, EU ETS, and domestic schemes in the UK, US, Kazakhstan, Korea, China and and sector specific schemes such as EU MRV, UK MRV and IMO DCS, enables me to advise both global and local players, on all sustainability issues wherever they are. I relish opportunities to design regulations, guidance, standards, schemes, and management systems and in understanding and implementing approaches and tools for them for business benefit. I have helped governments and organisations work through the maze of technical, operational and commercial issues that must be navigated to realise the opportunities of new regulatory requirements in these areas. I am privileged to have written for leading publications and speak on climate change and sustainability subjects at a variety of events. I have also designed and delivered tailored workshops and training courses on numerous subjects including: Extended Producer Responsibility, Recyclability Assessments, Environmental Auditing, Environmental and Energy Management Systems, Carbon Footprinting, Net Zero approaches, Verification, CSR, EU ETS, MRV and Electricity Capacity Markets for specific organizations, governments and business groups.

I hold a BA from Brown University and an MSc from The University of Oxford, UK, am a Professor of Marketing for Sustainability at various institutions, and live in Chicago, IL.

I’m an ethical and reliable person with a strong experience as HR Management consultant, mainly for large international companies (but also NGOs at the beginning of my path). In the last years, I have decided to join the interest for people with the care for the environment, starting a new path in sustainability. My mission is to help save the world, respecting people, animals and nature. In my professional life, on the one hand this is translated in helping organisations set and implement HR policies, by encouraging an ethical and sustainable approach for the wellbeing of people and the organisation itself. I can support companies in reaching their strategic sustainable goals through the HR tools. On the other hand, it is translated in raising awareness on our social and environmental impact, writing, guiding along the road to sustainability, visiting schools, providing courses and being an activist.
