Our operational expenses may rise due to costs associated with operating and maintaining our facilities, obtaining new emissions controls, paying taxes or fees for our Ghg emissions, or managing and administering a Ghg emissions program. Furthermore, changes in regulatory policies that result in a decrease in demand for hydrocarbon products could have adverse effects on market demand and prices for our production of crude oil, natural gas, and other commodities. Additionally, the increasing attention to global climate change risks has led to a rise in costs and potential litigation from governments.
