We promote environmental stewardship across our company by managing our use of resources and working to help preserve the planet for future generations.


To create a more secure world, we pledge to be responsible stewards and mitigate our impact on the planet. Our long-term climate goals and plans are aligned with science-based targets to address climate change and support the transition to a low-carbon economy.
Our goal
- We aim to reduce our global scope 1 and scope 2 market-based greenhouse gas (GHG) emissions by 65% by 2034 and achieve net- zero GHG emissions by 2050, which aligns with the Science Based Targets initiative’s (SBTi) 1.5°C scenario.
Our progress towards our 2034 GHG reduction target

- Total scope 1 + location-based scope 2 emissions baseline
- Total scope 1 + market-based scope 2 emission target
- 2024 actual performance
- Reduction from the baseline year
Energy-efficient technologies and access to renewable energy sources help us meet our broader goals and further reduce our impact on the environment. We’re mindful of our water consumption and recycling efforts. We’ve formulated action plans to improve our performance. We’ve also established a system and policy modeled after ISO14001 and designed to:
- Reduce energy use and GHG emissions
- Improve water efficiency
- Reduce waste to landfill
- Increase employee awareness
We don’t consume significant amounts of energy and water or produce significant amounts of waste. But we’ll continue to routinely measure these areas of our operations to better understand our impact on the environment.
