Recognizing the urgent need to address climate change, in September 2021 P&G announced an ambition to achieve net zero emissions across our supply chain and operations. To help pace our progress on reducing Scope 1 & 2 GHG emissions, we have established the following 2030 goal:
Reducing emissions across our global operations by 50% vs. 2010 baseline. From 2010 to 2022, we have reduced absolute Scope 1 & Scope 2 emissions across our global operations 57% through energy efficiency and renewal energy sourcing. As we continue to reduce emissions, we are also advancing natural climate solutions which will balance any residual emissions from our operations that cannot be eliminated by 2030.
Expanded use of renewable electricity helped enable our 57% reduction in our Scope 1 & 2 emissions. Even though we've exceeded our Ambition 2030 goal to reduce absolute emissions across our operations by 50% versus 2010, our work is by no means complete. While we are well on our way to utilizing 100% purchased renewable electricity, the next big challenge is reducing, and eventually eliminating, emissions from natural gas. There are significant hurdles that need to be overcome. With that in mind, we've partnered with 18 other manufacturers and local governments to create the Renewable Thermal Collaborative. This coalition is committed to scaling up renewable heating and cooling at their facilities in order to dramatically cut carbon emissions.
We update key categories of Scope 3 emissions on an annual basis, relying on estimates from LCA data as well as other available data sources. This year, we made several changes to our Scope 3 inventory which we feel better align with the guidance in the WRI/WBCSD GHG Accounting protocol. Key changes of note include:
