Innovation for Sustainable Products

At Dover, our sustainability efforts extend beyond our operations. An important part of our efforts involves developing products that are designed to help our customers meet their sustainability goals, run their operations more efficiently, and satisfy evolving regulatory and environmental standards.

Innovating to address customer needs is vital to value creation and to our competitiveness. Developing more efficient products that reduce carbon emissions in the use phase will also enable us to reduce our Scope 3 emissions, contributing to progress on our science-based target to reduce our Scope 3 greenhouse gas (GHG) emissions 15% by 2030 from a 2019 baseline. Scope 3 GHG emissions cover 15 categories of upstream and downstream activities. In 2022, 87% of our Scope 3 footprint was associated with category 11 emissions from the use of our sold products. Accordingly, we are focused on innovating to develop efficient, sustainable products that reduce carbon emissions in the use phase and addressing evolving customer and market demands. Our operating companies are well-positioned to capitalize on increasing requirements for sustainability, safety, and energy efficiency, and we strive to integrate these considerations into the design, development, and customer use of our products. This includes developing products and solutions that enable our customers to use resources more efficiently and reduce GHG emissions, while increasing reliability and durability. We primarily pursue innovation for sustainable products in three areas:

How Dover Innovates for Sustainable Products

The product management and research and development (R&D) teams at our operating companies lead innovation and product development, including with respect to sustainability. Product management and R&D teams regularly engage with our customers to assess ways we can help them achieve their business and sustainability objectives. These efforts are complemented with internal analysis of potential opportunities and unmet market needs.

Since 2021, four of Dover's largest operating companies by emissions have participated in quarterly workshops to discuss new methods for integrating sustainability considerations into product development and design. During these meetings, leaders from our operating companies and the Dover corporate center review emissions from the use of sold products, identify opportunities to consider sustainability at R&D checkpoints in new product development, and discuss initiatives to reduce product energy usage. As part of these quarterly meetings, operating companies learn and share best practices in new product development and sustainable innovation from industry and other operating companies. These meetings are an important component of our pathway to achieving Dover’s 2030 Scope 3 science-based target.

Our Scope 3, Category 11: Use of Sold Products emissions decreased by approximately 2% from 2019 to 2022. However, our Scope 3, Category 11: Use of Sold Products emissions increased compared to the previous reporting year. We conducted an analysis to understand the trend and have identified a few primary causes, including improved data collection and revenue growth from additional product sales as operations continue to rebound from the global COVID-19 pandemic. Furthermore, while our operating companies are working hard to innovate more sustainable products, there is a notable time lag in the product development process between the inception of a sustainable product idea and the realization of emissions reductions associated with that product. On average in our industries, the time from ideation to products in-use at scale is approximately 5-10 years. However, we are beginning to see our team's sustainable innovation come to market, including the recent launch of Environmental Solutions Group's electric refuse collection vehicle (eRCV). The eRCV is a significant milestone in the decarbonization pathway for the waste and recycling industries. Dover is currently considering a full re-baseline of 2019 data to adjust for updated methodologies used in 2022, which could result in a shift in the emissions trend. For more information on Dover’s progress toward our science-based target, see our Energy and Emissions webpage.

In 2022, R&D spend, including qualifying engineering costs, represented 1.9% of our annual revenue. Dover has maintained relatively consistent investment in R&D for the past several years and has increased R&D spend from 2015 levels, when it averaged 1.7% of annual revenue, partly in response to customer needs for more efficient, safer, and sustainable products. Ultimately, we view R&D as critical to maintaining the long-term growth and competitiveness of our product offerings in the marketplace as the global demand for more sustainable solutions continues to increase.

Reducing methane leakage and helping oil and gas operators achieve sustainability goals: Cook Compression

Cook Compression, and its parent company Dover Precision Components, develop solutions that help oil and gas operators reduce emissions, achieve their sustainability goals, and comply with regulations. The U.S. Environmental Protection Agency (EPA) estimates that over 200,000 packing systems in the U.S. natural gas industry are venting 200 million cubic feet of methane into the open atmosphere every day – a volume equivalent to filling two enclosed professional football stadiums. Across the oil and gas value chain, Cook Compression offers solutions that reduce these fugitive emissions while improving compressor performance.

In downstream oil and gas, where fugitive emissions are regulated, the industry-leading COOK CLEAN packing uses inert gas to create a barrier to gas leakage in gas compressors. In upstream oil and gas, updating to Cook Compression packing with packing with TruTech™ materials could reduce gas leakage rates by 80%. Cook Compression’s BTUU/BTRR rings also reduce gas leakage with a gapless design that eliminates leak paths and seals more effectively than conventional BTR rings, reducing fugitive emissions below measurable limits. For midstream oil and gas operators, Cook Compression Static-Pac® units eliminate up to 96% of fugitive emissions during compressor stand-by. In addition to minimizing direct emissions, Cook Compression valve solutions reduce indirect emissions by increasing operational efficiency and reliability and reducing compressor energy usage.
