Global warming places life on earth in danger, posing a threat to fresh water, food, and energy supplies. Greenhouse gas (GHG) emissions are the primary cause of global warming. Carbon dioxide (CO2), methane (CH4), and nitrogen oxides (NOx) are GHGs produced by the combustion of oil, fossil fuels, and other sources.
Approximately 2% to 3% of worldwide greenhouse gas emissions is generated by the technology and communication industry. GHG emissions are produced by industry operations such as energy consumption, product manufacture, and product use. According to the International Telecommunication Union, digital technology has the potential to reduce world carbon emissions by roughly 17%. Technology companies can help other industries improve their operational efficiency by cutting GHG emissions.
Hitachi Ltd (Hitachi) is a multinational company. It manufactures and sells information and telecommunication systems, power systems, social infrastructure and industrial systems, construction machinery, electronic systems and equipment, automotive systems, and smart life and eco-friendly systems. In fiscal year 2020, the technology company reported total GHG emissions of around 72.37 million tonnes CO2 equivalents (MtCO2eq), down 35% from 2019.
Scope 1, 2, and 3 emissions are the three categories of GHG emissions. Scope 1 are direct emissions from in-house fuel use and industrial processes. Indirect GHG emissions from production of electricity and heat purchased by the company, are referred to as Scope 2. Scope 3 emissions refer to the company's other indirect emissions beyond the company’s direct operations and occur in the company’s value chain, including upstream and downstream activities, such as purchased goods and services, transportation and distribution, and product use.
Scope 3 emissions account for most of Hitachi’s overall GHG emissions, accounting for 95.4% of total GHG emissions (69.06 MtCO2eq) in fiscal year 2020. In fiscal year 2020, the company's Scope 1 emissions fell by 20%, and Scope 2 emissions decreased by 28%.
Hitachi aims to achieve carbon neutrality in its business sites (factories and offices) by 2030. In fiscal year 2020, the company invested in 22 cases of energy-saving equipment with a total investment of $1.86 million. These investments contributed to an annual reduction of 447 tons of CO2 emissions.
