The Guardian According to a report, more than 24,000 kilometers of new oil pipelines are being built around the world, which is nearly twice the diameter of the Earth. The initiatives, led by the United States, Russia, China, and India, contradict efforts to limit global warming to 1.5°C or 2°C. If the pipelines are finished, the oil poured through them will emit at least 5 billion tons of carbon dioxide per year, which is similar to the emissions of the United States, the world's second largest polluter. Approximately 40% of the pipelines are already under construction, with the remainder in the planning stages. To meet internationally agreed-upon targets for mitigating global warming, global carbon emissions must fall by half by 2030.
