4/21/2021 Developing and deploying scalable technology solutions | ExxonMobil ExxonMobil has been working with the MIT Energy
Initiative to develop a new LCA tool that covers pathways of multiple technologies representing the majority of greenhouse gas emissions. This tool, called the Sustainable Energy System Analysis Modeling Environment (SESAME12), is based on
well-referenced peer-reviewed sources in the public domain and can perform full life cycle analyses for more than 1,000 technology pathways, from primary energy sources to final products or services including those from the power, transportation,
industrial and residential sectors. To have meaningful impact, greenhouse gas mitigation technologies must also be cost-effective. The use of techno-economic analysis (TEA) helps determine the most impactful and cost-effective ways to meet
global energy needs while reducing greenhouse gas emissions. TEA also helps to transparently inform policy development. TEA is currently being added to the SESAME model. Once completed, SESAME will compare both the emissions and costs of energy
technologies across all sectors in a system-wide setting. It will be publicly available as a transparent and open-source web tool designed for both experts and general users. Pictorial example of one pathway included in the SESAME tool: natural gas
production and power generation to the end use in an electric vehicle. 1 Edenhofer, O. et al (2014) Climate Change 2014: Mitigation of Climate Change. Contribution of Working Group III to the Fifth Assessment Report of the Intergovernmental

Data updated as of April 2020 and based on cumulative anthropogenic carbon dioxide capture volume. Anthropogenic CO2, for the purposes of this calculation, means CO2 that without carbon capture and storage would have been emitted to the atmosphere,
including, but not limited to: reservoir CO2 from gas fields; CO2 emitted during production and CO2 emitted during combustion. It does not include natural CO2 produced solely for enhanced oil recovery. 4 TDA Research, Pilot unit testing at NCCC
