We are significantly affected by governmental regulations on a global basis that can increase costs related to the production of our vehicles and affect our product portfolio, particularly regulations relating to fuel economy standards and GHG emissions. Meeting or exceeding the requirements of these regulations is costly, often technologically challenging and may require phase-out of internal combustion propulsion vehicles in certain major jurisdictions, and these standards are often not harmonized across jurisdictions. We anticipate that the number and extent of these and other regulations, laws and policies, and the related costs and changes to our product portfolio, may increase significantly in the future, primarily motivated by efforts to reduce GHG emissions. Specifically, fuel economy and GHG emission regulations at the federal, state or local level or in international jurisdictions could require us to further limit the sale of certain profitable products, subsidize the sale of less profitable ones, change our manufacturing processes, pay increased penalties, purchase additional credits from our competitors or undertake other activities that may require us to incur additional expense, which may be material. These requirements may increase the cost of, and/or diminish demand for, our vehicles. These regulatory requirements, among others, could significantly affect our plans for global product development and, given the uncertainty surrounding enforcement and regulatory definitions and interpretations, may result in substantial costs, including civil or criminal penalties. In addition, an evolving but un-harmonized emissions and fuel economy regulatory framework that could include specific sales mandates may limit or dictate the types of vehicles we sell and where we sell them, which can affect our revenues and profitability. Refer to the "Environmental and Regulatory Matters" section of Item 1. Business for further information on regulatory and environmental requirements.
We expect that to comply with fuel economy and GHG emission standards and mandates to sell specific volumes of ZEVs in certain jurisdictions, we will be required to sell a significant volume of EVs, and potentially develop and implement new technologies for conventional internal combustion engines, all of which will require substantial investment and expense. There are limits on our ability to achieve fuel economy improvements over a given time frame, primarily relating to the cost and effectiveness of available technologies, lack of sufficient consumer acceptance of new technologies and of changes in vehicle mix, lack of willingness of consumers to absorb the additional costs of new technologies, the appropriateness (or lack thereof) of certain technologies for use in particular vehicles, the widespread availability (or lack thereof) of supporting infrastructure for new technologies, especially with respect to EVs, the availability (or lack thereof) of the raw materials and component supply to make batteries and other elements of EVs, and the human, engineering and financial resources necessary to deploy new technologies across a wide range of products and powertrains in a short time. There is no assurance that we will be able to produce and sell vehicles that use such new technologies on a profitable basis or that our customers will purchase such vehicles in the quantities necessary for us to comply with current or future regulatory requirements.
In the current uncertain regulatory framework, compliance costs for which we may be responsible and that are not reasonably estimable could be substantial. Alleged violations of fuel economy or vehicle emission standards could result in legal proceedings, the recall of one or more of our products, negotiated remedial actions, fines and penalties, restricted product offerings or a combination of any of those items. Any of these actions could have a material adverse effect on our profitability, financial condition and operations, including facility idling, reduced employment, increased costs and loss of revenue.
In addition, many of our advanced technologies, including AVs, present novel issues with which domestic and foreign regulators have only limited experience, and will be subject to evolving regulatory frameworks. Current or any future regulations in these areas could impede the successful commercialization of these technologies and impact whether and how these technologies are designed and integrated into our products, and may ultimately subject us to increased costs and uncertainty.
