We are pleased to have published our 2022 ESG Report which highlights the Company's environmental, social, and governance (ESG) strategies, activities, progress, metrics, and performance for 2021, which is available on our website under the tab “ESG.” The report is responsive to the Sustainability Accounting Standards Board (SASB) Multiline & Specialty Distributors sector standard and includes additional disclosures responsive to the framework established by the Task Force on Climate-related Financial Disclosures. We are committed to regular, transparent communication of our progress and look forward to bringing our stakeholders along with us on this journey. We encourage you to review our ESG report, which includes additional detail in regard to certain our key efforts highlighted below.
Community Participation. We believe community participation and charitable giving enrich the neighborhoods where we work, live and play. We are proud of these efforts and we encourage participation by all dealerships and employees, including through our commitment to the Paralyzed Veterans of America (“PVA”). Since 2015, our dealerships have supported the PVA, an organization working to ensure paralyzed and disabled veterans receive the care, benefits, and job opportunities they deserve. Each year, we match certain donations from our customers and team members to the PVA and have contributed more than $8.5 million to the group. As a company with a presence spanning four continents, we are able to make positive impacts well beyond the borders of the communities where our dealerships are located. After the outbreak of the war in Ukraine, we and our affiliate Penske Transportation Solutions made a $1 million contribution to World Central Kitchen, an organization working to supply meals to those in need at the frontlines of humanitarian, climate, and community crises. We encouraged team members to also donate to this cause, raising over $150,000 from employees.
Environmental Sustainability-Electric Vehicles. Our dealerships sell and service vehicles that are engineered and manufactured by over 35 of the world’s automotive OEMs. Our new car dealerships sell the full suite of vehicles offered by our manufacturer partners, including hybrid, plug-in hybrid and pure electric vehicles (“EVs”). EVs can reduce the emissions that contribute to climate change and smog, improving public health and reducing ecological damage.
We encourage the sale and use of EVs and are actively placing charging stations across our network to facilitate a reliable infrastructure for their use. As of December 31, 2022, our network of EV charging stations across the U.S. and the U.K. totaled over 1,600, including a combination of Level 1 (standard), Level 2 (240V), and Level 3 (fast charging) capabilities. We expect to install additional charging stations to support EVs as our manufacturer partners introduce more of these products to the marketplace. We estimate that approximately 23% of our new vehicles sold in 2022 in the U.S. and U.K. combined were either electric or hybrid electric vehicles.
Managing our Energy Use and Reducing Waste. We are committed to monitoring and managing our energy use and the environmental impacts of our business. We recognize our responsibility to advocate for a cleaner environment through self-awareness, leveraging our global partnerships, promoting cleaner driving vehicles through our dealerships and reducing pollution and waste. We have deployed several strategies for reducing or optimizing our energy use, such as installing LED lighting, occupancy sensors, energy-efficient glass, and high-efficiency heating, ventilation and air conditioning (HVAC) systems.
We are committed to reducing the environmental impact of waste produced at our facilities. We deploy several strategies to ensure the efficient use of resources and responsible disposal of waste, including hazardous waste, and use third parties to manage, collect and process recycling for many of the materials that go through our service departments. Other strategies to reduce pollution and waste include recycling worn-out tires collected from participating U.S. retail dealerships and eliminating the use of paper for internal communications and customer documentation.
Human Capital, Diversity, Equity and Inclusion. We believe that our employees are our greatest asset. We understand that exceptional customer service can only be consistently delivered by attracting, motivating, training, and retaining the very best team members. With this in mind, we put our employees at the heart of everything that we do by developing their talent and enabling them to build long-term careers.
We are committed to building a diverse and skilled workforce while providing a work environment that promotes equity and is free from any form of discrimination on the basis of race, color, creed, religion, sex (including breast feeding and related medical conditions), pregnancy, sexual orientation, gender identity and expression, marital status, national origin, ancestry, citizenship status, uniform service member and veteran status, age, genetic information, protected medical condition, disability, or any other protected status in accordance with all applicable federal, state, and local laws.
Investor Outreach. We have an investor outreach program that aims to engage prospective and current shareholders throughout the year. Engagement activities includes participation in industry conferences and events, sell-side research conferences, one-on-one meetings with current and potential investors, quarterly financial results conference calls, and visits to our locations.
