We are committed to advancing several implementation changes and new technology adoptions, which will further improve our performance.

In 2020, Range Resources completed the sales of our North Louisiana and conventional assets. For consistency purposes and to enable benchmarking of data in the future, the 2020 environmental data reported in this section and throughout the report excludes data from these assets.
Range is committed to minimizing flaring. Minimal operational flaring is necessary under certain conditions in almost all oil and gas development to maintain a safe work environment. The emissions from this activity must be reported under regulatory requirements. When flaring is required, we deploy efficient combustion technologies to ensure minimal flaring.
In 2020. Range Resources completed the sales of our North Louisiana and conventional assets. To enable benchmarking of data in the future, the 2020 environmental data throught the report excludes data from this asset. Prior year data has ot been restated and reflects ownership of the asset.
Range is proud to have endorsed the World Bank’s “Zero Routine Flaring by 2030” initiative, becoming one of the first natural gas producers to join. This initiative closely aligns with our own commitment to environmental stewardship of continuing to reduce GHG emissions intensity.
Range continues to report emissions from flaring in accordance with federal regulatory definitions, as seen in figure 8.17, which has been our approach since we launched our first Corporate Sustainability Report. The AXPC definition of flaring (flaring of wellhead gas from the primary separator at assets) has been used for alternative calculations by our industry. Under those circumstances, Range has zero emissions flared from hydrocarbons. For more information see page 82 in the Appendix.
Range uses zero emission flowback turn-on procedures. This is achieved through a closed-loop system that utilizes existing permanent production facilities and temporary flowback equipment. This process allows us to flow volumes directly to an existing pipeline, eliminating the need for flaring during this critical phase. While drilling a typical oil or gas well, a minimal amount of hydrocarbons from geologic formations may need to be safely combusted on site. Range utilizes high-efficiency flaring technology which functions as a safety and control device and is used to combust unrecovered hydrocarbon emissions.
We continue to make progress on reducing emissions from flaring. Several of the initiatives discussed previously specifically contribute to the reductions of flaring activity, including the following initiatives:
Figure 8.17 shows the total quantity of hydrocarbons flared and their associated emissions from 2017 to 2020. The emissions from flaring increased with higher production until the initiatives were implemented in 2019. 11 percent of our GHG emissions are due to flaring, a slight increase compared to 9 percent last year. This is a result of a slight increase in the volume of hydrocarbon flared in Pennsylvania (a 9 percent increase), but primarily due to the significant reductions we saw this year from our other sources of GHG emissions. This reflects many of the emission reduction initiatives previously mentioned. Both numbers used in these calculations are also impacted by the sale of Range’s North Louisiana-based assets.
