Sustainability: Environmental Impact Overview

Empowering a sustainable, connected, and safer world.

Our Environmental Impact and Reduction Target

In 2021, we established an intensity target to reduce our Scope 1 and Scope 2 greenhouse gas (GHG) emissions 38% by 2035, in line with the Paris Agreement to keep global temperatures below 2°C above pre-industrial levels.

Littelfuse is committed to responsibly conducting its manufacturing and distribution operations to protect our employees, communities, and the environment. Littelfuse manufacturing facilities either follow or are certified to a management system aligned with ISO 14001 in 2021, which provides us with a means to assess our environmental impacts. In addition to formalized projects in resource conservation, our sites use our enterprise lean six sigma manufacturing operating system to seek reductions in waste generation and raw material, energy, and water usage.

Energy Efficiency

Energy efficiency is a critical component of our business strategy to provide necessary technologies for the marketplace. We develop products to address the increasing demand for renewable energy technologies, including smart meters, wind turbines, solar panels, energy storage systems, power optimization, and the electrification of transportation applications and increased efficiency of industrial motor drives.

Water Use

We strive to use our natural resources responsibly and have implemented enterprise lean six sigma projects throughout our facilities to help optimize water usage. Our business is not uniformly water intensive. However, our semiconductor facilities use more water than our comparably sized electronic assembly facilities. Most of our sites are in water stress areas, as determined by Four Twenty Seven results and Aquaduct Projected Water Stress rankings ( While we are focused on our facilities that operate in areas of water stress, we also are looking at opportunities for improving water conservation at all facilities.

Greenhouse Gas Emissions

A key element of our sustainability strategy is to reduce our carbon footprint. Our continued greenhouse gas (GHG) reduction efforts and priorities are based on a goal to achieve a Scope and 1 Scope 2 reduction of 38% by 2035.

In addition to our initiatives to reduce the impact of our manufacturing footprint, we have initiated the review of our broader business impact through collecting our Scope 3 GHG emissions data. This data is our first step towards building our strategy to manage our Scope 3 GHG emissions.

Waste & Hazardous Materials Management
Waste and Hazardous Materials Management

The foundation of our waste reduction strategy is centered on three concepts: reduce, reuse, and recycle.

Our Enterprise Lean Six Sigma teams hold innovation events and project competitions to encourage our employees to develop creative ways to eliminate or reduce waste throughout our business and production processes.

Many of our manufacturing facilities use hazardous chemicals in production. Our chemical handling procedures meet or exceed compliance with federal, state, and local health and safety regulations and include requirements for training, chemical handling, labeling, storage, communications, personal protective equipment, and emergency response.

Our teams are working to find creative solutions for reducing the use of hazardous chemicals.

Product Development & Innovation

During 2021, we created a product environment compliance steering committee to help elevate our product environmental strategy, governance, systems, communicate business goals and objectives, and align with internal information technology teams and resources. We also made significant software investments in product environmental management technology and developed our strategic roadmap.
