This report provides an overview of the current situation and future scenario for automotive CO2 emissions regulations, with a focus on passenger cars. The report highlights that the main drivers influencing current regulations include oil dependency and climate change, which are leading OEMs to constantly review and adjust their car portfolios. The report predicts that countries that are currently regulated will not change their policies, with the exception of China and India, which will introduce stricter standards due to factors such as a booming population and increasing demand for road transportation fuel. Unregulated countries, such as Russia and the Middle East, will rely on their abundance of resources and not adopt any CO regulation. The report identifies the United States and the European Union as leaders/trendsetters in the field of automotive CO2 emissions regulations.
