This page now serves as the proceedings for ETHOS 2021

For Presentation group sessions, please watch any of the 10-minute talks of interest to you ahead of the scheduled live session. The hour-long live session will be spent discussing the talks prepared for that session. While presenters will give a 1-minute reminder of their talk at the beginning, the sessions will proceed on the assumption that you’ve already viewed the 10-minute talks ahead of time. There is no pre-work for the 1 hour Panel sessions.

Please see the “Further Instructions” tab for further instructions. 🙂

Full details by day are listed below this table.

Monday Plenary Panel: From implementation to impact – Measuring longer-term impact on stakeholder goals

While all projects have the best intentions for real-world impacts, sometimes projects turn out differently than we would expect as we move along the time scale from implementation to short-term outcomes and long-term impacts. In the wise words of the late Kirk Smith, “We don’t get what we expect, we get what we inspect” indicating how important measuring the true outcomes may be. This panel will highlight how global partners seek to quantify these longer-term impacts of projects to determine which stakeholder goals have or have not been met and in what ways.

Panelists: Nuhu Amin, Stanford collaborator in Rohingya camps in Bangladesh; Thomas Thivillon, PhD candidate in development economics, PSL University; Olivier Lefebvre, Climate Solutions Consulting; Gemara Gifford, Trees Water People; Ricardo Piedrahita, Berkeley Air Monitoring Group; Danny Wilson, Geocene

Wednesday Plenary Panel: Business Model Innovation for Scale

Clean cooking is a 3-billion person problem. Impacting this problem requires solutions that have meaningful performance, adoption, and scale (I=PAS). This panel will focus on innovative business models that can scale to create impact in the clean cooking sector. Our panelists operate enterprises and agencies that aim for scale (>100k customers). In this session, panelists will answer the question “how will my organization’s business model achieve impact through scale?”

Panelists: Brenda Biteete, Private Sector Foundation Uganda; Ken Newcombe, C-Quest Capital; Richard Lawrence, Proyecto Mirador & Cool Effect; Ankit Mathur, Greenway Appliances; Peter Scott, Burn Manufacturing

Thursday Plenary Panel: You Get What You Incentivize – What donors should value (and stop valuing) to yield effective programs

Programs that mean to improve household and community energy sources are driven by many motivations. Some of these motivations align with physical, social and programmatic principles that yield lasting improvement in the situations of the target population, and some do not. Failures teach lessons that can improve future endeavors, but they need to be discussed and evaluated honestly. Seeds of success should be identified, too. Panelists will discuss how donor motivations have led to program designs that are aligned or misaligned with real-world success, and everyone is requested to participate in the spirit of honesty and future improvements. 

Panelists: Sebastian Africano, Trees Water People; Evan Thomas, UC Boulder; Carlo Talamanca, Otago; Rebecca Wentworth, Burn Manufacturing Co., Elisha Moore-Delate, UNCDF

Friday Plenary Panel: Field Perspectives on Adoption

This session will focus on the adoption component of the I=PAS equation, which as we’ve discussed this week reminds us that impact is a function of performance, adoption and scale. Full impact benefits require that cooks acquire, maintain and use clean and efficient technologies and fuels correctly, consistently and exclusively. Rarely does that happen in actual practice for our sector. How can we do better? Panelists will share their experiences and lessons learned over years of research and implementation, working to understand and influence adoption in the field.

Panelists: Mbumba Chigalu, National Cookstove Steering Committee, Malawi; Nafisah Abubakar, Head of Secretariat, RUWES, Nigeria; Alison Filler, International Lifeline Fund; Michael Johnson, Berkeley Air Monitoring Group
