Salesforce’s unique approach to advancing sustainable aviation
In this episode, we talk to Jamila Yamani, Director of Climate & Energy at Salesforce, who shares fascinating insights into the company’s commitment to sustainability, and how the company is taking a unique approach to advancing sustainable aviation as a non-airline entity.Yamani discusses why sustainability matters to Salesforce, emphasising that it’s not just about risk mitigation but also about leveraging their platform to accelerate the global transition to net zero. She highlights Salesforce’s role in sponsoring the Sustainable Aviation Challenge, launched by UpLink in partnership with the World Economic Forum and the First Movers Coalition, which aims to identify and elevate promising sustainable aviation technologies globally.As part of the First Movers Coalition, Salesforce has committed to buying SAF certificates equal to 5% of their air travel emissions. Yamani shares the challenges of navigating SAF certificates and off-takes as an end buyer, and how Salesforce has made initial purchases with United and JetBlue to start figuring out the complexities.To address the risks of greenwashing, Salesforce emphasises the importance of considering the full lifecycle impacts of SAF, especially fuels from biological resources. Yamani stresses the need for a diverse portfolio of SAF solutions and the critical role of sustainable feedstock sourcing.If you LOVED this episode you’ll also love the conversation we had with Andrew Chen, Principal for Aviation Decarbonisation at RMI, who discusses the RMI’s multi-faceted approach to aviation decarbonisation.

RMI's multi-pronged approach to decarbonising aviation includes SAF & contrails
In this episode, we talk to Andrew Chen, Principal for Aviation Decarbonisation at RMI. Founded in 1982 as Rocky Mountain Institute, RMI is an independent, non-partisan, non-profit that seeks to transform the global energy system to ensure a clean, zero-carbon future. Chen discusses RMI's multi-faceted approach to aviation decarbonisation, which includes stimulating demand for Sustainable Aviation Fuels (SAF) and addressing aviation's non-CO2 emissions – specifically, the environmental impacts of contrails. He also touches upon RMI's broader mission concerning the decarbonisation of heavy industry and transportation sectors.Central to the conversation is the pivotal role of SAF in reducing aviation's carbon footprint. Chen discusses how RMI, through initiatives like the Sustainable Aviation Buyers Alliance (SABA), is working to overcome the challenges posed by the current "green premium" associated with SAF. This involves mobilising corporate demand and leveraging technologies such as blockchain for the traceability of SAF certificates, thereby enhancing transparency and accountability in SAF transactions.Furthermore, Chen highlights the significant investments required to scale SAF production and the necessity of collaborative efforts across the aviation value chain for sustainable growth. He reflects on his experiences at Heathrow Airport, emphasising the critical role airports play in SAF adoption and the need for industry-wide collaboration.If you LOVED this episode you’ll also love the conversation we had with Elena Schmidt, Executive Director of the Roundtable on Sustainable Biomaterials (RSB), about the journey of RSB in fostering sustainability, especially in the aviation and travel industries.

From Legislation to Lift-off: The Drive for Sustainable Aviation Fuel in Washington
In this episode, we talk to Senator Andy Billig, Senate Majority Leader at Washington State Senate, on how he has spearheaded efforts to integrate environmental stewardship with legislative action in Washington State.Billig’s journey in sustainable aviation fuel (SAF) began in 2012, leading to pivotal legislation like Senate Bill 5447, which incentivises SAF production to complement Washington’s aerospace and technological sectors. The bill, developed through extensive consultation with stakeholders and aimed at boosting local SAF production, has been well-received for its flexibility and environmental focus. Despite challenges in educating legislators and addressing misconceptions about SAF versus other green technologies, the bill passed with near-unanimous support.Post-passage, significant strides have been made, including SkyNRG’s plant establishment and BP’s exploration of a SAF production facility, marking progress in Washington State’s SAF ecosystem. Billig addresses concerns about the bill’s scope and the need for a balanced, data-informed approach to SAF development, emphasising the role of technology-neutral legislation and the importance of market dynamics in resource allocation. He highlights the need for continued education, collaboration, and ensuring the sustainability of feedstocks, reflecting on the complexities of advancing SAF within the broader context of environmental and economic sustainability.If you LOVED this episode you’ll also love the conversation we had with Dr Susanne Becken, Professor of Sustainable Tourism at Griffith University, Australia, who discusses various aspects of sustainable travel and its relationship with climate change.

Are eFuels the holy grail of sustainable aviation fuels?
In this episode, we talk to Amy Hebert, Chair of the Board and CEO at Arcadia eFuels, who discusses the rapidly growing field of sustainable aviation fuel (SAF), with a focus on e-fuels. eFuels are produced with electricity from renewable sources, water and CO2 and are a sustainable alternative to fossil fuels. Hebert discusses her entry into the field, driven by the untapped potential for carbon-neutral fuels despite existing technologies like Gas to Liquids and green hydrogen electrolysers. Arcadia, her company, aims for rapid market entry and large-scale e-fuel production, targeting significant reductions in CO2 emissions. She highlights challenges in securing long-term offtake agreements and the evolving understanding of e-fuels in the market. Hebert also acknowledges the current resource intensity of e-fuels and the high costs of SAF production, emphasising the need for smaller-scale projects and technological advancements. She shares that Arcadia has not yet started producing SAF, with production expected to begin around late 2026 or early 2027. The conversation covers the importance of securing long-term commitments for green hydrogen, engaging with potential customers, and exploring innovative financing solutions. Amy's vision is to enable airlines to use 100% eSAF, facilitating responsible and cost-effective air travel.If you LOVED this episode you’ll also love the conversation we had with Gene Gebolys, President and CEO at World Energy, the world’s first producer of sustainable aviation fuel (SAF) that has been in the business of renewable fuels for over 25 years.
