The expenses incurred in our operations may include expenses for operating and maintaining our facilities, applying new emissions controls, paying taxes or fees for our Ghg emissions, or managing a Ghg emissions program. Furthermore, changes in regulatory policies that reduce demand for hydrocarbon products could have adverse effects on market demand and prices for our production of crude oil, natural gas, and other commodities. Furthermore, the growing attention to global climate change risks has led to a higher probability of government investigations and civil litigation, which could increase our costs or adversely impact our business.
