The result of this initiative extends not only to businesses who operate in Nevada, but also to the residents of the state.
Prologis’ environmental, social and governance (ESG) program is good business— benefiting our customers, investors, communities and employees. Good ESG practices support our corporate commitment to enduring excellence and advance our longstanding focus on exemplary customer service. Importantly, environmental stewardship at Prologis delivers business value to our customers and minimizes our impact on the environment based on how we locate, construct and operate our logistics real estate properties. Because sustainability is increasingly central to our customers’ brands and business models, our sustainable buildings give us an edge in attracting and retaining top companies. For example, building more energy-efficient facilities helps meet growing customer needs for electricity to power innovative supply chain automation and robotics technologies. Further, building facilities in locations close to end consumers reduces transportation distances. As the global leader in logistics real estate, Prologis has long been ahead when it comes to placing solar-generating arrays on our rooftops. In 2018, Prologis added 11 megawatts (MW) of solar, bringing the total to 186 MW of generating capacity in nine countries. Together, these installations produce enough emissions-free energy to power approximately 27,500 average U.S. homes each year.
“Prologis was among the first in the logistics real estate industry to invest in solar, and our future-focused approach to environmental, social and governance practices has put us on pace to surpass our goal of 200 MW of solar capacity by 2020.”
Since the inception of our solar program in 2012, we have developed 66 solar projects at 51 properties with a total installed capacity of 63.4 megawatts (MW). Solar production from these systems is anticipated to create 83.2 million kWh of renewable electricity annually or more than 25% of the common area grid consumption of our shopping centers. As part of our solar program we installed 2MW of solar arrays at Altamonte Mall, FL, in 2016. Altamonte is a prime example of Brookfield’s strategy, integrating solar installations as part of a wider energy efficiency scheme at the property. This has resulted in significant reductions in grid purchased electricity. In 2014 the property consumed 3,770,688 kWh of grid electricity. At the end of 2018 our solar production exceeded the property’s energy needs by 400,000 kWh. Altamonte is the absolute definition of a net+ zero building.
“We are proud to participate in the Solar Energy industry’s advancements. It has allowed us to make significant strides in our use of carbon-free electricity across our assets within the USA. Solar production supports our ambitious sustainability goals, embraces our culture to ‘Do the Right Thing’ and provides a financial benefit to our portfolio through reduced utility costs.”
Macy’s and Bloomingdale’s stores, as well as other Macy’s, Inc. facilities, have been updated over the past decade in order to meet our sustainability goals.

Hartz began its development of solar projects in 2009 with a 412KW array atop the Meadowlands Exposition Center in Secaucus, New Jersey. Its entry into the solar business came as a result of an increased focus on sustainability throughout its real estate portfolio and their 20 million square feet of flat industrial warehouse roofs in New Jersey. The incentives offered by the state of New Jersey coupled with the favorable federal tax treatment for solar development made it an easy decision for Hartz to invest in solar projects. Rather than leasing their roofs to another developer, Hartz decided that it will develop, own and manage all of the arrays within its portfolio. Over the course of the last decade, it has grown its solar portfolio to 34.3MW and it continues to develop additional projects as opportunities arise.
“With 20 million square feet of flat industrial warehouse roofs in our New Jersey real estate portfolio and the incentives made available by the state of New Jersey for solar, our decision to make a significant investment in the development of solar projects was an easy one. We continue to build out our portfolio as opportunities arise.”
ALDI cares about advancing efficiency and reducing environmental impact among its facilities nationwide. In 2018 alone, our solar production prevented the release of CO2 emissions equal to those created by an average car driving across the United States 12,427 times, or 15.6 million pounds of coal being burned. Our use of clean, solar energy grew to include rooftop solar systems on nine distribution centers and 99 stores. We've also expanded solar projects across thirteen states. ALDI continues to pursue projects aimed at minimizing our carbon emissions and impact on the environment. Our renewable energy portfolio continues to remain an important piece of that strategy in making long-term improvements.
“At ALDI, we’re committed to increasing efficiency across the board – and nothing is more efficient, and sustainable, than solar energy. By decreasing our carbon footprint and improving our green building standards across all of our stores, we’re investing in the energy of the future.”

The FedEx strategy of Reduce, Replace, Revolutionize helps us serve our customers more resourcefully, be more responsible in our communities, and be better stewards of the environment. We reduce the impacts from our activities, we replace assets to ensure the right solutions are utilized in the right applications, and we revolutionize the process by adopting cutting-edge technologies and solutions like solar energy. FedEx currently has 19 U.S. facilities with on-site solar technology, with four more internationally. In fiscal year 2018, these systems generated over 19 million kWh of clean energy in the U.S. Three new facilities were built in 2018 including our FedEx Ground facility in Maui, HI. Our Maui project is our first solar-plus-storage system. The 58.7 kW system consists of 163 solar panels and utilizes 6 Tesla Powerwalls to provide 81kWh capacity of battery storage. Powerwalls are rechargeable lithium ion batteries with liquid thermal control. The system generated 74,644 kWh over the last 12 months. This is compared to the 12,000 square foot facility’s total usage of 75,636 kWh. However, not all of the generated solar electricity was consumed on site. The electricity generated is purchased from the system owner and the project developer, Maui Sunrise Harvest LLC. Like many other islands, Hawaii’s electricity generation is heavily dependent on imported petroleum resulting in high electricity prices and emissions. This installation uses Hawaii’s abundant solar resources to reduce our energy costs, emissions, and provides increased reliability should there be a disruption to the grid.
“We reduce the impacts from our activities, we replace assets to ensure the right solutions are utilized in the right applications, and we revolutionize the process by adopting cutting-edge technologies and solutions like solar energy.”
Challenge 3 of Toyota’s Environmental Challenge 2050 calls for eliminating carbon emissions from its sites by 2050. By the end of 2018, Toyota had installed over 15 MW of solar arrays at its sites in Plano, TX; Ontario, CA and San Antonio, TX. The solar installations at its sites in Plano and San Antonio are the first and second largest corporate solar installations in the state of Texas. The company is expanding its use of renewable energy as a means of reducing its carbon footprint and reliance on non-renewable energy sources.
“Toyota is implementing a strategic plan to reduce carbon emissions and have a net positive impact on the planet. One way we reduce carbon emissions is by powering our facilities with renewable energy and we have found that solar makes a good business case.”
L’Oréal’s U.S. Operations facilities have been running on 100% renewable electricity since 2016, with solar projects in 3 state states—New Jersey, Arkansas, and Kentucky—and solar arrays covering 54 miles across the United States. L’Oréal USA’s Florence facility hosts the largest commercial solar array in Kentucky, providing 1.42MW of power through 4,140 solar panels, and saving 1,324 metric tons of CO2 per year. The 686,000 sq. ft. plant, where haircare products are made for the Garnier, L’Oréal Paris, Matrix, and Redken brands, is the company’s largest manufacturing site in the U.S. and its largest worldwide by tonnage of products produced. L’Oréal USA’s North Little Rock plant houses the third largest commercial solar array and the fourth largest solar project in Arkansas. The 3,600 solar panel installation provides 1.2 MW of renewable electricity and reduces the company’s carbon emissions by 556 metric tons per year. The 450,000 sq. ft. factory has operated in the state for over four decades, and is home to cosmetics production for brands including Maybelline, L’Oréal Paris, Essie and Lancôme.
“L’Oréal is committed to using its scale for good, and we work hard to ensure that our operations have a positive impact in the communities in which they’re based.”
