In 2016, of the estimated 4.6 million tonnes of gross GHG emissions from their operated oil and gas assets, 4.1 million tonnes were Scope 1 emissions, primarily from flaring and fuel combustion. In 2016 their absolute GHG emissions decreased by 1.0 million tonnes compared to 2015, due primarily to reduced flaring in North Dakota related to gas capture enabled by infrastructure enhancements and reduced production in that region due to weak oil prices, as well as reduced flaring in Equatorial Guinea related to a decline in production.
