This metric is based on the Global Reporting Initiative (GRI) G4 Guidelines. It covers one of the requirements of Indicator G4-EN31​ - 'Total environmental protection expenditures and investments by type'

​Measuring environmental mitigation and protection expenditures allows organizations to assess the efficiency of their environmental initiatives. It also provides valuable input for internal cost-benefit analyses. Data on environmental performance measured against environmental mitigation and protection expenditures offers insights into how effectively the organization uses resources to improve performance. When tracked and analyzed in a comprehensive fashion over time, this expenditures data allows the organization to judge the value of complex organizational or technological investments for improving environmental performance.

It is possible to establish a full environmental management accounting system within an organization that tracks multiple categories of information. This Indicator focuses on waste disposal, emissions treatment, and remediation costs, as well as prevention and environmental management costs.


This metric is asking for the total environmental protection expenditures and investments of the company in US dollars:

For WikiRate researchers:

Companies who align reports to GRI’s Sustainability Reporting Standards often include a GRI Content Index or Annex where GRI disclosures, with GRI codes, are listed.

  • Use the GRI Index, CTRL F, Command F or search button on source preview to search for this index and metrics within the report

  • Use G4 codes, G3 codes or keywords to quickly find values, keeping in mind that some companies report on the metric using different terms, e.g. G4-EN31 or EN31, environmental protection expenditures or environmental protection investments

  • Always check the metric question and methodology for the unit of measure or currency - researchers may need to carry out calculations or conversions before entering the final metric value

  • Add comments documenting exactly where within the source you found the information (page number) and include details of simple or complex calculations or conversions made to determine the metric value

  • If you are unable to locate a metric value in a source you can search for additional sources where the data is available and add a new source

Further guidance on how to research values for GRI-based metrics is available here, including detailed guidance on adding, editing and Checking metric values.

Global Reporting Initiative compliance guidance for companies:

To calculate the total environmental protection expenditures - G4-EN31​:

​Identify waste disposal, emissions treatment, and remediation costs based on expenditures which include, as a minimum:

  • Treatment and disposal of waste

  • Treatment of emissions (such as expenditures for filters, agents)

  • Expenditures for the purchase and use of emissions certificates

  • Expenditure on equipment, maintenance, and operating materials and services, and related personnel costs

  • Insurance for environmental liability

  • Clean-up costs, including costs for remediation of spills as reported in G4-EN24

Identify prevention and environmental management costs based on expenditures which include, as a minimum:

  • Environmental education and training

  • External services for environmental management

  • External certification of management systems

  • Research and development

  • Extra expenditures to install cleaner technologies (such as additional cost beyond standard technologies)

  • Extra expenditures on green purchases

  • Other environmental management costs

The compilation of the expenditures in this Indicator exclude the following categories as defined in the IFAC International Guidance Document on Environmental Management Accounting (21):

  • Fines for non-compliance with environmental regulation (see G4-EN29)

Reporting on this Indicator should include the following contextual information as a comment to the metric value:

  • ​The total environmental protection expenditures by:

    • Waste disposal, emissions treatment, and remediation costs

    • Prevention and environmental management costs
