The 2010 Deep Water Horizon oil spill in the Gulf of Mexico caused the tourism industry to lose $2 billion in revenues and the commercial fishing industry to lose $250 million in revenues. BP spent $6 billion on clean up efforts that year, including spending on labor and equipment. How did this event affect 2010 US GDP? The $2.25 billion in losses to tourism and fisheries were subtracted from GDP. The $6 billion in spending on clean up was included as output in US GDP. The revenue losses to tourism are included in GDP. Even though those revenues were not earned the potential for income remained. None of these values affected US GDP
