(Reuters) - The world's biggest oil and gas companies have set varying targets to reduce greenhouse gas emissions from their operations and the combustion of the products they sell.
Scientists say the world needs to cut greenhouse gas emissions by around 43% by 2030 from 2019 levels to stand any chance of meeting the 2015 Paris Agreement goal of keeping warming well below 2 degrees Celsius (3.6 Fahrenheit) above pre-industrial levels.
