Carbon neutrality refers to the goal of reducing greenhouse gas emissions to zero overall by 2050. Greenhouse gases such as CO2 are said to be the cause of climate change, including global warming. To address the issue of climate change, it is necessary to work on reducing greenhouse gas emissions through the promotion of carbon-neutral initiatives, such as the introduction of renewable energy. In the development of technologies for carbon-neutral initiatives, we will introduce technologies that are useful not only for analysis but also for practical demonstration experiments in the field.
