- Increased overall electricity consumption at KLA operational sites (14.8% year-over-year in 2023) due to expansions at Super Sites in the U.S. and Singapore.
- Nonhazardous waste increased 15% in 2023 over 2022 due to cleanup efforts at multiple sites, building expansion in Singapore, and construction projects at our sites in the U.S., Belgium and Germany.
- Evolving rules and regulations in the trade compliance environment presented new compliance challenges.
