Carbon Counts works with a range of partners and Associates. They include:

Andrew Howard

Andrew is a long-standing acquaintance of Carbon Counts, and has been collaborating with the team on various assignments and opportunities since the start of 2016.


Andrew left the UNFCCC Secretariat in Bonn at the end of 2015 after 16 years of service. During his time at the UNFCCC Secretariat he was instrumental in the initial design of the CDM, JI and emissions trading under the Kyoto Protocol, their subsequent implementation and, more recently, the further development of these mechanisms. Since 2009, he was alternately Manager (Strategy, Collaboration and Communications) for the Sustainable Development Mechanisms (SDM) Unit at the UNFCCC and Secretary to the CDM Executive Board and the JI Supervisory Committee. Andrew led the Secretariat’s thinking in the last years on how the CDM can be developed and adjusted to strengthen its integration with climate finance and national climate policy, and also led the secretariat’s work to develop Article 6 (cooperative approaches and mechanisms) in the Paris Agreement.


Justin French-Brooks (Word-to-Dialogue)

Justin is a freelance consultant and has worked with Carbon Counts on several projects relating to international climate policy in the past. Justin’s professional background is in the sustainability arena with over 10 years' experience in both the private and public sectors, including the UK Government and its associated environmental delivery bodies. Justin holds degrees from Cambridge University and Imperial College, London.


Jonathan Slater (The Blue Globe)

Jonathan is an independent consultant working in the field of prize design and environmental technology innovation. Jonathan specialises in energy and technology prizes and grand challenges. He was formerly Director of Business Innovation for the EMEA region at InnoCentive, where he managed and/or lead over 30 large scale prize designs. Recent and ongoing projects include prize design for the US Government Office of Naval Research Science and Technology’s Energy Storage Challenge, the UK Government’s Department for International Development (DFID) Ideas to Impact project and several innovation prizes undertaken in the Middle East, Saudi Arabia and UAE.
