Japan could be the world’s fifth largest carbon emitter however its leaders are unequivocal of their dedication to do higher.
“Being carbon neutral by 2050 is the long-term strategy that Japan has mapped out, and we plan to see it through,” prime minister Fumio Kishida informed the UN’s COP26 local weather convention in Glasgow final yr. Like his predecessor, Yoshihide Suga, he additionally vowed to chop CO₂ emissions by 46 per cent from 2013 ranges by 2030.
While such pledges usually are not uncommon, Japan could also be higher positioned than a lot of its Asia-Pacific friends to satisfy them. Research by McKinsey, the consultancy, signifies that Japan might want to spend 4.2 per cent of its GDP on the bodily property required to chop emissions and safe low-carbon development till 2050, in contrast with India’s 10.8 per cent and China’s 5.2 per cent.
This benefit is mirrored within the FT’s inaugural Asia-Pacific Climate Leaders checklist, compiled with Nikkei Asia and information supplier Statista. Of the 200 corporations on the checklist — comprising companies which have considerably reduce their Scope 1 and a couple of greenhouse gasoline emissions relative to income — 86 are from Japan, excess of some other nation. Scope 1 and a couple of emissions come up, respectively, from a enterprise’s personal operations and from producing the vitality it buys.
But regional pre-eminence will not be the identical as world pre-eminence. Japan’s reliance on coal elevated after regulators took most nuclear energy crops offline within the wake of the Fukushima catastrophe in 2011, and it lags Europe in renewable vitality. About 20 per cent of its electrical energy comes from renewables, which is roughly half the equal determine for the EU — although which will work to its benefit within the quick time period.
“Japan is likely to keep [its] decarbonisation cost relatively lower than the EU until 2030, as there is still ample room for its existing mature technologies to reduce emissions,” says Yuito Yamada, a associate at McKinsey. He argues that the nation can obtain large wins shortly by constructing extra photo voltaic and wind energy amenities, changing oil and coal boilers to much less carbon-intensive gasoline, and switching from petrol to electrical autos.
Japan’s geography, nonetheless, limits its means to rely closely on photo voltaic and wind energy. Solar farms are ideally located on degree floor, however 70 per cent of Japan’s territory is mountainous. And, as an island, it’s more durable for Japan to faucet different nations’ grids to compensate for fluctuations within the provide of electrical energy from renewables.
Yamada warns that “costs will rise substantially by 2050” if web zero is to be achieved, as a result of the emphasis should shift to newer, costlier applied sciences similar to hydrogen energy and carbon seize and storage (CCS).
Some of Japan’s heavy industrial companies, historically large emitters of greenhouse gases, see alternatives right here. To encourage them, Kishida has promised lavish subsidies, and has mentioned that state and company spending on inexperienced applied sciences will attain ¥150tn ($1.1tn) over the following decade.
Eisaku Ito, chief expertise officer of Mitsubishi Heavy Industries, believes hydrogen and CCS expertise could also be cheaper to implement than some analysts predict if corporations make the most of present amenities and provide chains. “We are in a transition period,” he says. “Technology doesn’t change all in one day but it will rather take a couple of decades.”
Mitsubishi executives assume present gasoline generators could be run in a extra eco-friendly method by fuelling them both with hydrogen — at solely minimal further value whether it is sourced close by — or with pure gasoline from which carbon is captured after combustion.

Along with US multinational General Electric and Germany’s Siemens, MHI is without doubt one of the world’s largest suppliers of gasoline generators. It additionally has a considerable share of the marketplace for CCS crops, and has developed smaller and cheaper variations of those to broaden their use.
Next yr, it plans to construct a pilot hydrogen energy facility in western Japan, the place it could possibly check the complete course of from producing hydrogen to producing energy. MHI has earmarked ¥2tn for growing decarbonisation applied sciences till 2030, and has set itself a web zero goal of 2040, together with not solely Scope 1 and a couple of emissions, but in addition so-called Scope 3 emissions, that are produced alongside the remainder of the worth chain.
Meanwhile, it has managed to cut back vitality use at its personal crops over the previous few years by calculating the quantity of vitality that’s theoretically required, after which evaluating it with the truth.
Another advocate of carbon seize is development firm Kajima. It has co-developed a kind of concrete that absorbs and locks in CO₂ when it solidifies. Conventional concrete has an enormous carbon footprint as a result of the cement it incorporates generates plenty of emissions throughout manufacture — nevertheless it additionally has the numerous benefit of being cheaper than Kajima’s inexperienced product.
Kajima, which is able to obtain a authorities subsidy value ¥25bn over the following decade for its carbon-absorbing concrete, is making an attempt to supply it extra cheaply. But Yoshitake Yoshimura, who heads the group’s setting initiatives, factors out that value is just one amongst a number of concerns.
“Providing materials that help customers make decisions could be more important,” he says. He desires them to “understand how much emissions they can reduce by pouring that amount of money in.”
Faced with rising buyer demand for environmental information, Kajima has began to measure carbon emissions in any respect of its almost 1,000 development tasks — the primary initiative of its sort in Japan’s development sector, in accordance with Yoshimura.
Yukimi Yamada, a researcher at consultancy the Japan Research Institute, says that, whereas Japanese corporations have helpful low-carbon applied sciences, they’re behind their European counterparts in turning them right into a enterprise. But she thinks which will change as Kishida’s insurance policies take impact.
“With the government’s aggressive subsidies, more companies are now increasingly investing people and money into decarbonisation to boost businesses,” she says.
McKinsey’s Yamada says that, whereas Japanese corporations have thus far lacked the dynamism to develop their low-carbon applied sciences in Europe, substantial alternatives await them there. His argument is that, as development in Europe’s renewables sector turns into more durable to maintain, demand for hydrogen and CCS will surge, offering a helpful check mattress.
“It is important for Japanese companies to train first in Europe to become globally competitive and then bring [knowhow] back to Japan,” he suggests.
