Oxy is committed to responsible environmental stewardship in
its operations, and applies the Health, Environment and Safety
Management System (HESMS) to manage environmental performance
systematically. The HESMS facilitates compliance with
environmental laws and regulations; using energy, land, water
and other natural resources efficiently; preserving habitat and
biodiversity; controlling emissions; managing and mitigating
environmental risks; responsibly remediating the company’s past
operating or waste management practices; and pursuing continuous
improvement in environmental protection.
This section describes environmental topics and indicators
identified by Oxy’s stakeholders as being most relevant. Key
environmental issues addressed in the upstream oil and gas and
chemical manufacturing sectors include resource consumption,
land use, emissions and waste generation.
Oxy’s focus on expanding oil and gas production from
long-lived, mature assets and chemical production at existing
facilities provides substantial environmental and social
benefits. Doing so extends the productive life of infrastructure
on lands where construction and industrial activity have already
occurred, although it increases marginal energy requirements and
certain emissions on a production-weighted basis.
