The article examines the recent carbon footprint reduction measures taken by BP and Eni, which have set the goal of achieving carbon neutrality by 2050. Both companies are developing solar and wind energy, starting to produce “green” hydrogen, implementing carbon capture and storage programs, expanding electric car refueling networks, and offsetting CO2 emissions by planting forests. In addition, they plan to gradually cut oil and gas production and radically change corporate structures, creating new business units and transforming from international oil companies to energy companies of a wide profile. American oil companies, such as ExxonMobil and Occidental, stick to oil and gas, hoping for hydrocarbons demand recovery in the future, and for the time being they just keep improving energy efficiency and reducing the carbon intensity of their activities. However, it is obvious that under the new US president, attention to climate policy will increase. American oilmen, whose climate awareness will also be prompted by consumers, environmental organizations, financial institutions and their own shareholders, may have to step up decarbonization efforts.
