In 2022, Brazilian oil and gas company Petrobras had 68 places staked out for oil exploration off the South American coast, searching for new reserves while spending $6.9 billion in oil development projects. About the same time, Algeria-based Sonatrach proclaimed its ambition to ramp up production to become a top five national oil company by 2030. All these companies, along with 33 others focused on oil and gas, sent delegations to Egypt for last year's annual climate summit, known as COP27, aimed at moving the world away from the burning of fossil fuels like oil and gas.
