Glossary

A law enacted in 1998 to reduce greenhouse gas emissions and prevent global warming in Japan. It requires businesses to calculate their greenhouse gas emission amount and report them to the government. emission amount are calculated using the formula activity amount x Emission factor, and emission amount up to the previous fiscal year are reported to the minister with jurisdiction over the business.

An index showing the strength of the impact that greenhouse gases have on global warming. Using CO2 as a standard, it numerically expresses how much warming other greenhouse gases cause with the same amount. Since greenhouse gases have different life spans, the numerical value also changes depending on the length of the evaluation period. For this reason, it is necessary to Settings the evaluation period according to the intended use.

The tax is imposed on the use of all fossil fuels, including oil, natural gas, and coal, based on the emission amount that accompany the combustion of fossil fuels. It was gradually implemented from 24, and the final tax rate was reached in 28. The CO2 Emission intensity 1 ton of fossil fuel is used, and the tax rate is Settings at 289 yen per ton of CO2 emission amount (these are the initial tax rates, and are being increased in stages). Both individuals and companies bear the tax equally.

A system in which energy conservation standards for specific Energy intensive equipment designated by the Energy Conservation Law, such as energy conservation standards for electrical appliances and fuel efficiency/exhaust gas standards for automobiles, are set to performance standards that are equal to or higher than the performance of the "equipment with the best energy-saving performance" among products on the market at the time the Settings Settings.

Measures to combat climate change can be divided into 2 categories: mitigation and adaptation. Adaptation refers to measures to respond to the effects of climate change that are already underway and minimize the damage it causes. For example, strengthening embankments to protect against rising sea levels, introducing drought-resistant crops, and greening cities to protect against heat waves.

A phenomenon in which the average temperature of the Earth rises due to an increase in greenhouse gases such as carbon dioxide and methane emitted mainly by human activity. This causes melting of glaciers, rising sea levels, and an increase in abnormal weather, which has a major impact on the environment and ecosystems.

A carbon tax is a tax levied on activity that emit greenhouse gases such as carbon dioxide (CO2). The purpose of this tax is to encourage companies and individuals to reduce emission amount by imposing an economic burden on them for the environmental impact they cause when they use fossil fuels (coal, oil, natural gas, etc.).
