To manage our emissions effectively, we need to understand our greenhouse gas (GHG) footprint. Our Climate Change Action Plan drives improvements in the collection, identification and measurement of GHG data, GHG emission reduction projects and the consistent application of life-cycle analysis of GHG emissions to priority areas.

Details of our GHG emissions, natural gas flaring performance and energy efficiency may be found in our annual Sustainability Report.

External Reporting and Verification

Each of our business units is responsible for quantifying emissions and reporting the information to our corporate center for compilation and internal verification. Reporting to authorities and regulators is also the responsibility of business units.

The method of data collection at each individual source ranges from continuous emissions monitoring to emissions estimations. Estimating approaches meet applicable regulatory reporting requirements or industry guidance, as appropriate. The quality of estimating methodologies, measurements and calculations are audited on a routine schedule by our corporate HSE auditing team and periodically assessed by third parties.


The annual CDP survey collects a wide range of information concerning corporate efforts to manage climate change issues effectively and drive emissions reductions. It includes an emphasis on governance, strategy, actions and reporting to try to provide a complete view of companies’ performance for comparison. It also provides a view of sector performance. ConocoPhillips has participated in the survey since 2003. Our most recent CDP submission can be found in the 2018 CDP document.

Progress on our multi-year plan includes:

​Understanding Footprint ​
Improve greenhouse gas data
​Improve recording of greenhouse gas emission reduction projects 4
​Provide consistent life-cycle analysis of greenhouse gas emissions across the company 3

Improve GHG data — We made significant improvements in the quality assurance and quality control of data at the business unit level, building in review processes and clear separation of responsibilities to produce data.

Improve GHG emission projects data — We concentrated on improving the quality of data provided by business units to produce an internal GHG corporate marginal abatement cost curve. We have made changes to streamline data collection and improve comparability across business units.

Consistent life-cycle analysis — We drafted guidelines for our business units to be able to carry out GHG life-cycle analysis on a consistent basis. We co-led the IPIECA GHG Scope 3 reporting study to enable more consistency in reporting across the industry.
