We are subject to a variety of local, state and federal statutes, ordinances, rules and regulations concerning the protection of health and the environment, including those regulating the emission or discharge of materials into the environment, the management of storm water runoff at construction sites, the handling, use, storage and disposal of hazardous substances, impacts to wetlands and other sensitive environments, and the remediation of contamination at properties that we acquire, own or develop. In addition, state and local jurisdictions have in recent years enacted regulations that require new homes to be more energy efficient than existing homes, or to be more weather-resistant, or have mandated energy efficient features, such as solar panels, be included in new construction. The environmental and housing code regulations applicable to each community in which we operate vary greatly depending on the location of the community site, the site's environmental conditions and the present and former use of the site. Environmental regulations may cause delays, may cause us to incur substantial compliance, remediation or other costs, and can prohibit or severely restrict development and home building activity. In addition, noncompliance with these regulations could result in fines and penalties, obligations to remediate, permit revocations or other sanctions; and contamination or other environmental conditions at or in the vicinity of our developments, whether or not we were responsible for such conditions, may result in claims against us for personal injury, property damage or other losses.
From time to time, the United States Environmental Protection Agency and other federal or state agencies review home builders' compliance with environmental laws and may levy fines and penalties for failure to strictly comply with applicable environmental laws or impose additional requirements for future compliance as a result of past failures. Any such actions taken with respect to us may increase our costs or harm our reputation. Further, we expect that increasingly stringent requirements will be imposed on home builders in the future. Environmental regulations can also have an adverse impact on the availability and price of certain building components such as lumber.
In recent years, an increasing number of state and Federal laws and regulations have been enacted or proposed that deal with the effect of climate change on the environment. These laws and regulations, which are generally intended to directly or indirectly reduce greenhouse gas emissions, conserve water or limit other potential climate change impacts, may impose restrictions or additional requirements on land development and home construction in certain areas. Such restrictions and requirements could increase our operating and compliance costs or require additional technology and capital investment, which could adversely affect our results of operations. This is a particular concern in the western United States, where some of the most extensive and stringent environmental laws and residential building construction standards in the country have been enacted, and where we have significant business operations. We believe we are in compliance in all material respects with existing climate-related government regulations applicable to our business, and such compliance has not had a material impact on our business. However, given the rapidly changing nature of environmental laws and matters that may arise that are not currently known, we cannot predict our future exposure concerning such matters, and our future costs to achieve compliance or remedy potential violations could be significant.
Additionally, increased governmental and societal attention to environmental, social, and governance ("ESG") matters, including expanding mandatory and voluntary reporting, diligence, and disclosure on topics such as climate change, human capital, labor and risk oversight, could expand the nature, scope, and complexity of matters that we are required to control, assess and report. These factors may alter the environment in which we do business and may increase the ongoing costs of compliance and adversely impact our results of operations and cash flows. If we are unable to adequately address such ESG matters or fail to comply with all laws, regulations, policies and related interpretations, it could negatively impact our reputation and our business results.
