New research she conducted University of Massachusetts Amherst, suggests that 10 % of the wealthiest Americans contribute to 40 % of the nation's total greenhouse gas emissions. Study published in journal PLOS Climate it creates a link between income, especially income from financial investments, and the emissions produced to generate that income. The researchers recommend that to fairly achieve the goal of limiting global temperature rise to 1.5C, policymakers should adopt taxes targeting shareholders and the carbon intensity of investment income. Scientists and environmentalists have long known that consumption—the amount and type of food we eat, the cars we drive, and everything we buy—is closely related to greenhouse gas emissions. Traditional environmental policy then sought to either limit consumption or channel it into greener paths: replacing red meat with a plant-based diet or swapping a gas guzzler for an electric vehicle.
