Melinda Janki asks some pertinent questions about the Environmental Impact Assessment (EIA) for ExxonMobil’s Liza Phase 1 project. She identifies ‘data deficiencies’ in the profiling of marine species, compares the EIA to the requirements stipulated in Guyana’s Environmental Protection Act and analyses the oil spill scenarios in the EIA against the benchmark the actual spill caused by Exxon Valdez many years ago. These are edited clips from a presentation at Moray House Trust.
