【Digest of this week's topics】
Japan is charting an ambitious course to transform its industrial and energy landscape through 2040, targeting a 73% emissions reduction alongside plans to boost renewable energy to 50% and nuclear power to 20% of electricity generation. The government's $1.5 billion investment in ultra-thin solar cell technology signals its intention to challenge China's renewable energy dominance. Meanwhile, Japanese corporations are adapting to this green transition, though challenges persist in the automotive sector, where manufacturers face fierce competition from Chinese EV makers. The upcoming TECHNIUM Global Conference in May 2025 will showcase Japan's commitment to deep-tech innovation.
[🇯🇵📰👀Japan Climate News Headlines]
【1】Japan approves new climate, energy and industry policies through 2040 [2/19 Reuters]
The Japanese government has approved new climate change, energy, and industrial policies through 2040. The greenhouse gas reduction targets aim for a 60% reduction from 2013 levels by 2035 and 73% by 2040.
The energy policy sets goals to increase renewable energy to 50% of the electricity mix by fiscal 2040, with nuclear power accounting for 20%. This represents a significant increase from the current nuclear power share of 8.5%.
The plan also aims to develop industrial clusters in areas rich in low-carbon power sources. However, the goals remained unchanged despite over 80% of public comments calling for more ambitious targets. Additionally, offshore wind power, a key driver for renewable energy expansion, faces challenges from inflation and high costs, with Mitsubishi Corporation announcing a review of three domestic projects, raising uncertainties about policy implementation.
【2】Japan backs nuclear power in climate plan criticized as insufficient [2/18 The Japan Times]
Japan has announced plans to reduce fossil fuel dependency to 30-40% by 2040 while increasing renewable and nuclear energy. However, environmental groups are calling for more ambitious targets.
Greenpeace Japan suggests a 78% emissions reduction by 2035 to meet the 1.5°C goal. The Japan Climate Leaders' Partnership, representing the business sector, advocates for a 75% reduction by 2035, indicating broad support for more aggressive climate action.
【3】Japan submits to UN new target to cut emissions by 60% in FY2035 [2/18 NHK World]

As part of efforts to achieve net-zero emissions by 2050, the plan also includes a 73% reduction target by fiscal 2040. Public comments revealed mixed reactions, with some calling for higher targets while others expressed concerns about economic impacts.
【4】Japan companies cut CO2 emissions while expanding businesses, study shows - Increased renewable energy usage reduces the environmental cost of sales growth [2/13 Nikkei Asia]
Major Japanese companies reduced CO2 emissions per unit of sales by 31% from 2021 to 2024 while maintaining business growth.
The Adoption of renewable energy led to significant reductions in indirect emissions (scope 2)
Direct emissions (scope 1) reduction requires additional capital investment, presenting challenges for capital efficiency.
【5】Japan’s $1.5bn bet on ultra-thin solar cells in challenge to China - Tokyo aims to disrupt Beijing’s dominance of renewables and reduce fossil fuel dependence [2/16 Financial Times]
Japanese government invests $1.5 billion in ultra-thin solar cell development
Cells are 20 times thinner than conventional panels, enabling flexible installation
Aims to generate power equivalent to 20 nuclear plants by 2040
Sekisui Chemical leads development with ¥157 billion government subsidy
Initial costs three times higher than conventional panels, targeting urban markets
【6】Sky not the only limit for JAL and ANA’s climate goals [2/14 The Japan Times]
Japanese airlines are pursuing net-zero emissions by 2050 but face significant challenges in achieving this goal. While various approaches, including Sustainable Aviation Fuel (SAF), new aircraft deployment, and Direct Air Capture (DAC) technology, are being considered, high costs and technical limitations pose major obstacles. Additionally, balancing increasing tourism demand with environmental targets presents a significant challenge.
【7】Can Japan’s Carmakers Survive China’s EV Threat? - Honda and Nissan are losing market share at an alarming rate. The collapse of their merger talks may make things worse. [2/14 Bloomberg Original]
Japanese automakers, once dominant in the global market in the 1970s, are now facing a severe decline in market share, particularly in Southeast Asia.
As Chinese EV makers like BYD grow rapidly by offering electric vehicles across various price points, Japanese manufacturers struggle with their EV market entry timing and strategy.
The collapse of Honda-Nissan merger talks may further complicate this challenging situation.
