National oil companies (NOCs) are key players in the global oil and gas industry—they produce half of the world’s oil and gas, and invest 40% of capital into the sector. But policy-makers and climate activists alike often overlook NOCs’ role in global efforts to address climate change. Omission of NOCs from climate strategies will significantly hamper governments’ attempts to meet global climate goals, and NOCs—along with the countries that depend on their revenues—could be left behind.
