What the Movement Is
The global decarbonization movement has transitioned from ambition to execution. Governments worldwide are now embedding climate targets into industrial policy. At COP28, nearly 200 countries agreed to transition away from fossil fuels, described by UN Climate Change as “the beginning of the end of the fossil fuel era” (UN Climate Change: COP28 – What Was Achieved and What Happens Next?). The conference also called for tripling global renewable energy capacity and doubling energy efficiency improvements by 2030, both essential to keeping the 1.5°C goal within reach.
Meanwhile, financial flows are aligning with this shift. The International Energy Agency reported that global clean energy investment will reach $2 trillion in 2024, roughly double the amount still flowing into fossil fuels (International Energy Agency: Investment in clean energy this year is set to be twice the amount going to fossil fuels). This trend demonstrates that decarbonization has become not only a climate imperative but also a cornerstone of industrial and financial strategy worldwide.
Industry Trends Shaping Decarbonization
Several technology and market forces are driving the decarbonization movement forward.
Green hydrogen is one such example. It is expected to decarbonize hard-to-electrify industries like steelmaking and transport, yet Reuters notes that only 6 million tons per year of low-carbon hydrogen capacity currently exists or is under construction—far short of the 450 million tons needed by 2050 (Reuters: Green hydrogen retreat poses threat to emissions targets). Carbon capture and storage (CCS) is gaining momentum as well, with Japan setting a roadmap to capture and store 6–12 million tons of CO₂ annually by 2030 (Reuters: Japan sets carbon capture roadmap with 6–12 Mt/year target by 2030).
Efficiency improvements are also proving vital. The International Federation of Robotics identified “energy efficiency” as the number-one trend in automation for 2023, pointing out that robots designed with regenerative drives and smart power modes can cut factory energy use while boosting productivity (International Federation of Robotics: Top 5 Robot Trends 2023).
At the same time, carbon markets are expanding. Global carbon trading reached nearly $950 billion in 2023, with the EU ETS dominating market value as prices surpassed €100 per ton (Reuters: Global carbon markets value hit record $949 bln in 2023). Japan’s GX-ETS, currently in pilot phase, will become mandatory by 2026. To support compliance, companies are turning to digital platforms such as AWS’s Customer Carbon Footprint Tool, which enables organizations to measure emissions data in line with GHG Protocol standards (Amazon Web Services: Customer Carbon Footprint Tool).
These trends—new fuels, CCS, energy efficiency, and digital carbon tracking—illustrate where technology and policy are converging, and where companies must position themselves to remain competitive.
Why Act Now
The urgency for Japanese companies to act is reinforced by both regulatory and financial pressures. Europe’s Carbon Border Adjustment Mechanism (CBAM) will apply carbon costs to imports such as steel, aluminum, and cement starting in 2026, effectively leveling the playing field with European producers who already pay under the EU ETS (FTI Consulting: Implications of the EU’s Carbon Border Adjustment Mechanism for Asia). Domestically, Japan’s GX-ETS will require firms to manage and disclose emissions within just a few years.
Capital markets are also shifting. More than $130 trillion in global assets is pledged toward net-zero alignment, meaning investors are rewarding companies with transparent and credible decarbonization strategies. Those lagging behind may face higher financing costs or even divestment. For businesses across Japan, acting now is no longer optional; it is the only way to remain viable in global supply chains and attractive to international partners.
Exhibitor Introduction
Panasonic Corporation
Website: https://www2.panasonic.biz/jp/
Business: Electronics and energy solutions
Decarbonization Initiative: At its Kusatsu factory in Shiga, Panasonic launched the “H2 KIBOU FIELD” in April 2022, a demonstration plant designed to operate the facility on 100% renewable energy. The system integrates 99 units of 5kW pure hydrogen fuel cells, approximately 570kW of solar panels (1,820 units), and a 1.1MWh storage battery, all managed by an energy management system (EMS). The project covers peak demand of around 680kW and annual electricity needs of 2.7GWh. The EMS controls supply-demand balance every 30 seconds, enabling distributed power sources to follow factory demand. This on-site energy self-sufficiency model addresses challenges such as grid congestion and renewable fluctuations. Panasonic envisions expanding the concept as a commercial “RE100 Solution” in the future.
JERA Co., Inc.
Website: https://www.jera.co.jp/
Business: Power generation and energy infrastructure
Decarbonization Initiative: Together with IHI, JERA conducted the world’s first large-scale demonstration of 20% ammonia co-firing by heat input at its 1GW-class Hekinan coal-fired power plant. Results showed stable operability equivalent to conventional operations, no increase in NOx, a 20% reduction in SOx, and N₂O emissions below the detection limit. Building on these results, JERA is preparing for commercial implementation, with the technology targeted for establishment by March 2025. Ammonia, which does not emit CO₂ when burned, offers a pathway to decarbonize existing coal-fired plants. However, cost, supply chain, and lifecycle emissions remain under discussion, making this an important transitional technology.
