Emission Reductions
On our way to achieving net-zero emissions by 2040, we are working to reduce our Scope 1 & 2 emissions by 95% and our Scope 3 emissions by 50% (both against a 2019 baseline) by 2030.
Scope 1 & 2 emissions
As of year-end 2025, we have reduced our absolute Scope 1 & 2 emissions by 94%, against the 2019 baseline, reflecting continued progress toward our target and bringing us closer to our 2030 goal. By conducting in-depth reviews of equipment and technology in buildings leased by Booking Holdings and its brands, we created a real estate decarbonization roadmap that leverages energy efficiency upgrades, electrification and improved cooling technologies. We also maintained 100% renewable electricity sourcing across our offices through the purchase of unbundled energy attribute certificates (EACs), of which 95% are purchased within the country where the electricity is consumed.⁴
Scope 3 emissions
Our target is to reduce our absolute Scope 3 emissions by 50% against a 2019 baseline by the end of 2030 and by 90% by 2040. Emissions in this scope account for 99% of all of Booking Holdings’ reported GHG emissions and include the indirect emissions generated within our supply chain. In 2025, we strengthened the quality and precision of our Scope 3 greenhouse gas emissions inventory by incorporating activity-level data for a portion of our marketing spend. Applying this improved methodology resulted in our 2025 Scope 3 emissions measuring 30% lower than our 2019 benchmark year, and a 16% year over year reduction compared to 2024.
