We are subject to extensive federal, state, and local environmental, health and safety laws and regulations concerning matters such as worker health and safety, air emissions, wastewater discharges, hazardous material and solid and hazardous waste use, generation, handling, treatment and disposal and the investigation and remediation of contamination. We are subject to the risk of substantial liability and limitations on our operations due to such laws and regulations. The risks of substantial costs and liabilities related to compliance with these laws and regulations, which tend to become more stringent over time, are an inherent part of our business, and future conditions may develop, arise or be discovered that create substantial environmental compliance or remediation or other liabilities and costs.
Compliance with environmental, health and safety legislation and regulatory requirements may prove to be more limiting and costly than we anticipate. To date, we have committed significant expenditures in our efforts to achieve and maintain compliance with these requirements, and we expect that we will continue to make these expenditures related to such compliance in the future. From time to time, we may be subject to legal proceedings brought by private parties or governmental authorities with respect to environmental matters, including matters involving alleged contamination, property damage or personal injury. New laws and regulations, including those that may relate to emissions of greenhouse gases, stricter enforcement of existing laws and regulations, the discovery of previously unknown contamination or the imposition of new clean-up requirements, could require us to incur costs or become the basis for new or increased liabilities that could have a material adverse effect on our business, financial condition or results of operations.
We may also see an increase in costs relating to our steelmaking assets that emit relatively significant amounts of greenhouse gases as a result of new and existing legal and regulatory initiatives related to climate change. The United States government and various government agencies have introduced or are considering regulatory changes in response to climate change, including regulations aimed at reducing greenhouse gases through emissions standards, renewable energy targets, carbon emission pricing, and similar initiatives, and requiring heightened environmental monitoring and disclosures. These initiatives aimed at reducing greenhouse gas emissions may impact our operations directly or through our suppliers or customers, including increased environmental reporting, emissions control, capital equipment, energy, and other costs to comply. Any future climate change and greenhouse gas regulations could negatively impact our ability (and that of our customers and suppliers) to compete with companies situated in areas not subject to such regulations. Until the timing, scope and extent of any future legal and regulatory initiatives become known, we cannot predict the effect on our business, financial condition or results of operations.
While we are taking steps to significantly reduce our greenhouse gas emissions, there is no guarantee that we will be able to achieve our goals. Additionally, any costs related to the reduction of greenhouse gas emissions may be higher than we anticipated.
