The TMCA structure consists of three operating arms: National Sales and Marketing Operations, Product and Corporate Operations, and Regional Operations. Lexus Australia is managed as a separate division. Based on Toyota Australia's 14th Sustainability Report. It details business and environmental performance for the 12 months from April 1, 2019 to March 31, 2020, with the following information provided: Amidst the challenges of COVID-19, Toyota Australia has reached a significant milestone this year, celebrating 60 years of operations. From unassuming beginnings when we sold 69 cars in the first nine months of trading, to being the only car company in Australia to have sold 200,000 cars in a single year. We have maintained our position as the top selling automotive company in Australia for the 17th consecutive year and we are transforming to become the most admired mobility business. It was back in 2016 when we introduced our 2025 vision, Creating Innovative Mobility Solutions for All Australians. Since then, we have been adapting our strategies to reduce CO2 targets to fulfill our customers environmental aspirations, and ultimately our responsibility as corporate citizens. At Toyota, we are at the cutting edge of electrification, with our strategy built on hybrid vehicles and other alternative powertrain technologies such as hydrogen-powered fuel cells. In the current day, hybrid models play into the mindset of the consumer by offering competitive pricing, fuel savings and vehicle performance across a number of our model range, and in 2020 alone we have sold over 37,000 hybrids September year to date. This year we also completed the first stage of our Hydrogen Center at the Toyota Center of Excellence in Altona, Melbourne. This center is a step towards us meeting our target of zero CO2 emissions from our sites and vehicles by 2050 and aligns with our drive to promote sustainable mobility. Globally, Toyota has also been refocusing on mobility and emphasizing on new technologies. Developments such as Woven City, a fully integrated and connected ecosystem powered by hydrogen fuel cells, will allow us to maintain our leading position in the automotive sector. Here in Australia, we will take elements of this work and procure the components that suit our customer's needs. We have a leading role in the transition to a decarbonised future, and the recent announcement of a new voluntary CO2 standard by the Federal Chamber of Automotive Industries confirms our commitment to electrification, strongly aligning to Toyota's environmental action plans and our pursuit of growth in hybrid vehicles. Whilst we currently find ourselves in uncharted territory, our focus remains on our people. We are placing emphasis on our employee's and dealer's mental health, along with supporting our customers as they face challenges as a result of COVID-19.
