Energy transition leads Japan to record lowest level of Greenhouse Gases (GHGs) in history

At a very dangerous international moment, we must look atGreenhouse Gases (GHGs) – or Greenhouse Gases (GHGs) – with more attention, in a world that is changing under the weight of climate change. Which opens a wide discussion about everything that could prevent societies from achieving the Sustainable Development Goals (SDGs) in their social, economic and environmental dimensions.

This is because the greenhouse gas emissions file is no longer on its traditional path within major economies in particular; It is now going through a very complex stage of restructuring and transformation, and the reason for this is the increasing pressures of climate change, which are pushing countries to dismantle old models dependent on fossil fuels, and rebuild their energy systems on more flexible and sustainable foundations.

In this context, Japan is a revealing model of these global transformations in greenhouse gas levels, which we discuss with you in this article, measuring the role of different sectors in this transformation, in addition to measuring the impact of the energy mix in supporting the reduction of carbon emissions, while reviewing the path that Japan follows to achieve its climate goals; So keep reading.

Greenhouse gas indicators in Japan

Government data showed that Japan has recorded a noticeable and positive shift in the field of reducing Greenhouse Gases (GHGs) (gases that absorb infrared rays, raising the temperature of the planet), with a decline in energy consumption in the industrial sector, and an increased reliance on renewable and nuclear energy sources.

To realize this Japanese shift in reducing greenhouse gas levels, we must know that the fiscal year of 2024 – which ended in March 2025 – witnessed a decrease of 1.9%, reaching about 1.046 billion tons of carbon dioxide equivalent, compared to 1.067 billion tons in 2023; This would be the third annual decline in a row and the lowest level since data recording began in the early 1990s.

Sector emissions decline

More specifically, different sectors in Japan witnessed varying changes in emissions levels, as the industrial sector recorded a decrease of 2.5%, while transportation sector emissions decreased by 1.6%, and household emissions also decreased by 0.7%, and in contrast, the services and trade sector witnessed a slight increase of 0.2%.

This discrepancy reflects the different nature of economic and industrial activities and the extent of their impact on energy consumption, and also indicates the importance of adopting policies directed at each sector. In order to ensure a balanced and sustainable reduction in emissions.

Transformation in the energy mix

In addition to the role of Japanese government policies in this transformation, energy mix efforts have a significant role and contribution, as Japan worked to raise the rate of renewable energy’s contribution to total electricity production by 23.1%, in addition to increasing the share of nuclear energy by 9.4%, with a decrease in dependence on coal and gas.

From the Fukushima crisis to the emissions reduction path

On the other hand, Japan witnessed a noticeable increase in harmful emissions following theFukushima nuclear accidentin 2011; Due to excessive reliance on fossil fuels to compensate for the shutdown of nuclear reactors. Emissions peaked in 2013 at about 1.394 billion tons, before gradually decreasing with the resumption of operation of some reactors and increased reliance on renewable energy.

Therefore, Japan has set an ambitious goal of reducing its emissions by 46% by 2030, especially since it has succeeded – so far – in reducing these emissions by about 24.9%. This crystallizes Japan’s sustainable steps towards building its energy systems and sources, in order to achieve the seventh goal: clean and affordable energy.

In depth, the Japanese experience in reducing carbon emissions reveals a deeper shift in the logic of managing the economy itself. Energy has become a tool for redefining the relationship between the state, the market and the environment, because when a major industrial country succeeds in breaking the traditional link between growth and emissions intensity, it redraws the limits of the possible in an equation that has always seemed difficult, and this equation is: How do we grow without consuming the future?

So,The Earth Guards Foundationsees that climate change and the accelerated commitments it imposes towards the transition to clean energy are reshaping public policy priorities; So that it is compatible with comprehensive sustainable development paths and its seventeen goals before it is too late.
