Stelios Pesmajoglou

Director, Professional Programs


Stelios Pesmajoglou is responsible for developing the Professional Certification Programs of the GHGMI.

Stelios has more than 14 years of national and international experience on a broad range of issues relating to climate change. His main area of expertise is policy and technical aspects of climate change mitigation, including: negotiations on climate change issues; evaluation of mitigation options for the reduction of greenhouse gas emissions; development of guidelines on reporting and review of information under the UNFCCC and its Kyoto Protocol; preparation and technical evaluation and auditing of greenhouse gas emission inventories; and national reports on actions to address climate change.

Between October 1999 and July 2008, Stelios worked at the UNFCCC secretariat, where he held positions of increasing responsibility. From January 2006 until July 2008, he was the leader of the Analysis and Methods sub-programme that dealt with: mitigation of climate change; land use, land-use change and forestry (including reducing emissions from deforestation in developing countries); emissions from international aviation and maritime transport; and research and systematic observation. Stelios organized all workshops for the dialogue on long-term cooperative action to address climate change and coordinated the drafting of the final report by the co-facilitators – the result of the negotiations on this dialogue was the adoption of the Bali Action Plan in December 2007.

Between October 1999 and December 2005, Stelios worked on both methodological and political issues, including: supporting the negotiations on the development of guidelines on reporting and review of information under the Convention and the Kyoto Protocol; and contributing to the development of rules and modalities for the three Kyoto mechanisms (international emissions trading, clean development mechanism and joint implementation). Stelios coordinated and organized greenhouse gas inventory review activities, and undertook and supervised methodological work related to the improvement of methods for the estimation of greenhouse gas emissions from various sources.

Stelios is a contributing author to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories and the WBCSD/WRI Greenhouse Gas Protocol.

Before joining the UNFCCC secretariat, Stelios worked at the National Observatory of Athens, in Greece, (March 1995 to September 1999) where he participated in the national delegation responsible for the negotiations on the Kyoto Protocol. As an expert adviser to the Greek Ministry for the Environment, Physical Planning and Public Works, he participated in national and international meetings and workshops that focused on the implementation of policies and measures, particularly for the energy sector. Stelios established the basis of a national system for the preparation of national greenhouse gas inventories of Greece and compiled inventories of emissions of greenhouse gases and ozone precursors for Greece. He also participated in national and international research programs that dealt with developing energy supply and demand scenarios on CO2 emissions for Greece; implementation of wind energy projects; and the development of environmental pressure indicators for air pollution and acidification.

Stelios completed his studies at Imperial College of Science, Technology and Medicine (London, United Kingdom) and has a Bachelors degree in Aeronautical Engineering; a Masters degree in Computational Fluid Dynamics and Structural Mechanics; and a Doctorate in Aerodynamics of Wind Turbines.

Why I Work at the Institute

There are several reasons why anyone of us decides to work for a company or organization: because the job offered is what we always wanted to do; because of the salary and perks; because of what an organization stands for; because of the experience that we will gain; because of the people who work there; because it was the only company that would hire us; because of all of the above and a lot more…

So far, I have been blessed to have worked (mostly by accident rather than design) with people and for organizations that not only have been pioneering in what they do, but have also been true to their dreams, goals, ambitions and above all humanity. Looking back and to the present, there are several qualities (for lack of a better word) that attracted me to various jobs, but one quality that first comes to mind is: Commitment. And although commitment can take different forms and shapes, it should be reciprocal if it is to be an asset for an organization rather than a liability.

In relation to our Institute, working with the GHGMI team over the course of the last 18 months, I have come to respect all of my colleagues for their dedication to the mission of the organization and for their boundless support to each other despite differences and, at times, radically opposing points of view. But above all, I have become part of a very competent and hard-working team that is wholly committed to:

I am proud to be associated with this energetic team of individuals and for what we have achieved so far. Building GHGMI took a lot of hard work, personal sacrifices and unwavering commitment on the part of everyone involved. I am looking forward to the months and years ahead and to the new and exciting things that the future will bring.

Looking ahead, we are embarking on new initiatives that will require even more hard work, persistence and perseverance. I am confident that, with the support and commitment of my friends and colleagues, we will continue to provide the best possible service to the international society of GHG professionals and, in the process, we will do our part to make our world a little bit better than what it is today!
