Partnering to progress the SDGs

As a company founded on sharing our scientific research and discoveries to make the world a safer place, our environmental and sustainability experts today participate in and lead the important global dialogues surrounding sustainability. SDG No. 17 reveals the need for cross-industry, public, private and civil society partnerships to accomplish sustainability goals. We embrace this SDG through participating in collaborative research and demonstration projects and working directly with partners across the circularity value chain. In 2019, UL sustainability experts contributed to the following organizations to share insights, progress innovations and collaborate on advancing the SDGs:


Bloomberg Sustainable Business Summit — For the past two years, UL has been actively supporting the Bloomberg Sustainable Business Summits. In 2019, we shared how emerging technologies are driving sustainable action and measuring success. Key takeaways from the 2018 summit were captured here.

CE100 — UL became a member of the Ellen MacArthur Foundation CE100 in 2019, collaborating with industry leaders to advance circularity. One of the first projects UL worked on was a mass-balance approach to calculating recycled input generated through a chemical recycling process. 

GreenBiz — UL co-hosted GreenBiz’s inaugural circularity-themed conference, Circularity19. Circularity offers innovative ways to operationalize sustainability into business. To learn more, listen to this GreenBiz podcast episode 177: “Sounding off at Circularity19.” 

Global Cities, Inc. — UL is a longtime partner of the annual Pritzker Forum on Global Cities. This event brings together mayors, academics, nongovernmental organizations (NGOs) and industry stakeholders from around the world to share knowledge and practices to address the challenges facing cities today. This year’s forum focused on sustainable growth.

Sharing research and scientific expertise

U.S. Department of Energy (DOE) research — In January 2019, UL completed work on two DOE three-year research grants to further understand the life of photovoltaic (PV) modules in collaboration with team members from the National Renewable Energy Laboratory (NREL), National Institute of Standards and Technology (NIST), academia and industry. These projects will inform the PV industry about the best ways to design and develop materials and PV modules, promoting more durable PV systems that exceed the current performance and financial aspects of solar power. In 2019, we were awarded another DOE three-year research grant to extend our work analyzing the condition of fielded PV modules installed and operating in different environmental conditions around the U.S., and ultimately the world. 

National Institute of Standards and Technology (NIST) and UL workshop — In December 2019, UL co-hosted the first NIST/UL Workshop on PV Materials Durability at NIST’s campus in Gaithersburg, Maryland. This conference brings together leading scientific experts in solar power from around the world to address cutting edge ways to promote the best design, development, assessment and usage of solar power technologies.   

Energy Storage System (ESS) Safety — UL extended our thought leadership in energy storage system safety by developing key new requirements for safety. ESS supports renewables by capturing the energy from solar and wind, allowing it to be accessed when needed, even if the sun is not shining and the wind is not blowing. In late 2018, UL issued UL 1974, the U.S. and Canadian national safety Standard for Evaluation for Repurposing Batteries. This Standard promotes the safe reuse of EV batteries in the energy storage infrastructure, which helps extend resources, reduce waste and promote renewables. We followed our publication of the world’s first electrical energy storage (EES) safety Standard, UL 9540, the Standard for Energy Storage Systems and Equipment, with additional published requirements to address the fire safety of these systems. UL’s ESS and fire experts worked to issue new testing protocols that are being used by regulators around the country to help install ESS with confidence. 

Biofuel research and requirements — UL worked with U.S. National Laboratories, automakers, the agricultural sector and industry stakeholders to proactively research, develop and publish requirements for new biofuels. Our work to establish requirements for mid-level ethanol fuel blends will lay the foundation for safety of fueling stations, support more rapid implementation of infrastructure and accelerate the ability to use more biofuels that burn cleaner than gasoline and produce lower levels of nitrous oxide (NOx) and other air pollutants.

EV Charging — UL has been advancing requirements for EV fast charging technologies as well as EV wireless charging. Both of these technologies offer easier and safer EV charging, which supports broader uptake of EVs and other zero-emission vehicles by the public. As we see increased deployment of renewables, this allows for clean electricity to increasingly charge zero-emission vehicles (ZEVs) and reduces emissions from fossil fuels. Through summits, technical analysis, modeling and collaboration with key stakeholders, UL has been highly active in advancing safe, sustainable and practical ZEV tech. 

PV Rapid Shutdown/Hazard Control — As rooftop solar PV power becomes increasingly popular across the U.S. and the world, it presents challenges for the first responder community in carrying out their tactics in a building with rooftop PV. PV panels continue to generate electricity when exposed to light — whether sunlight or even the artificial lighting used by fire departments at night — that can generate enough electricity to injure or kill first responders if they come into contact. The presence of water in firefighting operations elevates the risk. UL has been working with the first responder community, the solar industry, the U.S. National Laboratories and others to help ensure the safety of new technologies that allow first responders to rapidly shut down the distribution of electricity from a rooftop PV array, keeping them safe as they carry out their critical missions. We conducted essential work with Sandia National Laboratories to assess the electric shock hazards for firefighters and are using that research to drive the optimal requirements for the use of that technology. This effort helps promote rooftop solar use while also protecting the lives of the firefighters. 

First hydrogen fuel station certification — In 2018, UL issued the world’s first certification of the safety of a hydrogen fuel station. These stations are used to fuel hydrogen fuel cell vehicles (HFCVs) like the Toyota Mirai. HFCVs are extremely clean, as their byproduct is water. In 2019, these stations began being installed in the U.S., in southern California, to promote safe and clean transport in a region challenged by air pollution from vehicles using internal combustion and diesel engines. 


International Electrotechnical Commission (IEC) Renewable Energy Scheme (IECRE) First Solar Certificate — The IECRE is a new conformity assessment scheme to promote easier global deployment of large scale wind, solar and marine power plants. UL has been deeply engaged in setting up the scheme since its inception, in all three sectors. In 2019, UL issued the first certificate under the solar sector for First Solar, a leading global manufacturer of innovative solar systems.
