Staff Engineer, Greenhouse Gas Emissions - Air Quality
USA
Valeria Alvarado Tejeda is a chemical engineer specializing in greenhouse gas (GHG) emissions across the oil and gas value chain. She supports a variety of emissions advisory and reporting projects, including life cycle assessments (LCA), basin wide methane initiatives, OGMP 2.0, leak detection and repair (LDAR) auditing, and methodology assessments.
Her experience includes analyzing large emissions datasets, evaluating greenhouse gas reporting frameworks, and supporting the development of emissions inventories and reporting protocols. Valeria has contributed to basin-wide methane measurement initiatives, LNG life cycle assessment modeling, PHMSA-supported LNG LDAR research, and updates to the NGSI Methane Intensity Protocol. She also performs LDAR audits at gas processing and refining facilities and collaborates closely with operators, technology providers, researchers, and industry organizations to improve emissions data quality and support methane management programs.
Valeria holds a Master of Science and Bachelor of Science in Chemical Engineering from Texas A&M University, where her graduate research focused on the techno-economic analysis and life cycle assessment of hydrogen production pathways.
