Toyota's 3rd generation HEV "Prius"
The Japan of the past was a country that remained largely unchanged for centuries. Gentle traditions such as the tea ceremony, idyllic rural villages, and a proud shogun history were the elements that shaped the nation. Then came World War II, which brought this proud country to its knees. In some places, such as Hiroshima and Nagasaki, the damage was physical and palpable. But the whole of Japan suffered as the costs of waging war left the nation economically crippled.
The rebuilding effort in the 1950s and ‘60s, however, transformed this bucolic nation into the economic powerhouse it is today. History tells us of the 19th-century industrial revolution in North America and Europe, yet no transformation has been more dramatic than that experienced in Japan since the 1950s. True, there had been a preview of socio-economic change with the industrialisation of the Meiji era (1868-1912), which coincided with that of the western world, but the post-war era brought sweeping changes.
This unprecedented development, of course, came at a cost to the environment in the form of pollution. The two oil price scares of the 1970s were also dramatically felt in Japan, which is almost totally dependent on imported natural resources.
But the nation turned its weaknesses to an advantage by moving quickly to develop low-impact, energy-saving technologies. By the dawn of the current millennium, with much of the rest of the world only just beginning to come to terms with renewable energy and climate change issues, Japan was at least 20 years ahead − and, indeed, has developed an entire business sub-sector centred on the technology.

Eco-cars
Take hybrid cars. Toyota and Honda, both Japanese companies, have been world leaders in this field, and look set to reap the rewards for their foresight and research.
Like many in the 2008-09 global financial crisis, the Japanese automobile industry experienced a serious downturn in demand. However, hybrid electric vehicles (HEV), combining an internal combustion motor with an electric motor, is the one sub-sector that is doing well.
Toyota's Prius has dominated the HEV market so far, but last February Honda introduced the second generation of their HEV, Insight, designed to knock Prius off the road. With a price below two million yen, the Insight became the best-selling car domestically in April in 2009. In May, Toyota counter-attacked with a full-model change of the Prius, which put Toyota back in top place in June after managing to keep the price of the new model down to just 2.05 million yen.
Toyota is now widening the gap, bringing out hybrid versions of its better-known models and expanding the hybrid drive train to its luxury brand, Lexus.
Pure electric vehicles (EV) are a newer development in the Japanese car market. In June, Fuji Heavy Industries began selling its Subaru plug-in Stella EV, which can be charged from household power outlets. Mitsubishi Motors meanwhile, has begun marketing its i-MiEV by leasing to corporations.
Not using petrol means zero emission of climate-changing carbon dioxide but there are some well-known disadvantages. The driving range is relatively limited. The Stella can travel a maximum of 90 kilometres before it needs recharging; for the i-MiEV it is 160 kilometres. Electric vehicles also have long recharge times. The Stella takes eight hours on 100-volt power, while the i-MiEV takes 14 hours.
Also, when compared with the same class of petrol-powered vehicle, they are expensive, so in the short to medium term their acceptance is expected to be limited.

Tax cuts
In April 2009 the Japanese government implemented tax cuts for environment-friendly vehicles. Cars powered by electricity, gas, diesel and hybrid engines are eligible for exemption or a reduction of vehicle taxes, depending on how eco-friendly and fuel-efficient they are. These tax concessions have been identified as a key incentive to boost the popularity of HEVs.

Electric appliance recycling
Before 2001, approximately 60,000 tonnes of electrical appliances were discarded by Japanese households every year, with most going to landfill. But in a country as compact as Japan there are limited landfill sites. So the government introduced the Electric Appliance Recycling Law to ensure that television sets, air-conditioners, refrigerators, freezers and washing machines are recycled. From April 2009, clothes dryers and liquid crystal and plasma flat-screen television sets have been added to the list of appliances that must be recycled.
The law makes it obligatory for retailers to collect such items from consumers and for manufacturers to retrieve useful parts. Consumers pay the cost of collection and transportation.



Introducing eco-points
According to government figures covering the residential sector, approximately 70 per cent of CO2 emissions come from electrical appliances, of which 50 per cent come from air-conditioners, refrigerators and televisions.
So another initiative in Japan's wide-ranging clean, green campaign is the introduction of an eco-points scheme. Customers who buy air-conditioners, refrigerators and digital televisions with high energy-efficient ratings receive eco-points which can be exchanged for gift certificates, coupons, eco-friendly merchandise and goods that promote regional development.
As well as being a counter-measure against global warming and a stimulus to the economy, this scheme is aimed at promoting the changeover to digital terrestrial television. The incentive is currently applicable only until March 31, 2010.

Solar power
Japanese households generating solar power from photovoltaic panels will, under a new proposal, be able to sell surplus electricity back to electricity companies for approximately double the purchase price. Japanese electric power companies currently pay 24 yen per kilowatt-hour but, under the proposed plan, they will pay consumers 48 yen.
This system of selling back surplus power at a fixed price is expected to be introduced before the end of 2009. The cost of buying back the power from households will be recouped by increasing electricity costs to the public. In Germany, after the implementation of a similar system, the use of new energy rose suddenly. It is expected that its introduction in Japan will also bring about a rapid increase in solar power installation.

Best 100 new energies
To encourage the adoption of alternative energy in Japan, the Ministry of the Economy, Trade and Industry (METI) and New Energy and Industrial Technology Development Organization (NEDO) announced awards for the "best 100 new energies".
Recipients include wind power, cryogenic energy, biomass fuel production, geothermal power, and temperature-difference energy (utilising the salt in sea water). Some of these ideas, of course, are hardly "new" but they have been reapplied to projects which have created power for "local consumption". As the catchline suggests, it is geared towards the adoption of clean energy in local areas.
For example, in Hokkaido, the town of Suttsu boasts the biggest municipally operated wind farm, consisting of 14 turbines taking advantage of the strong seasonal winds to generate power.
Again in Hokkaido, Toyako's agricultural co-operative's collection centre recently installed a system that uses 1500 tonnes of snow for a cryogenic facility to store potatoes at low temperatures.
In Mie prefecture, the Sharp Kameyama plant, which manufactures liquid crystal display television sets, uses 5210 kilowatts of solar power generated by a photovoltaic power system, the largest of its kind in the world.
In Kyoto, a biomass energy plant produces 220 kilowatts of electricity by using manure. And in Kagawa prefecture, the Shikoku Electric Power Company operates an unusual system which uses the temperature-difference of sea water in its thermal power station at a port terminal.
Meanwhile, Fukuoka Hydrogen Town in Kyushu is the result of collaboration between the public and private sectors. After the installation of 150 residential hydrogen fuel cell power generation units in houses, it will be the largest demonstration project of its kind in the world.(J)

Cool Biz campaign
In a nation known for its formality, Japan's approach to environmental challenges has been surprising for some. In 2005 the government began a campaign called Cool Biz, or Cool Business, encouraging office workers to wear short-sleeved shirts without jackets or ties in summer.
This meant that air-conditioners could be set at 28 degrees, in an attempt to cut electricity consumption and consequent carbon dioxide (CO2) emissions. According to Environment Ministry calculations, the reduction in greenhouse gases was approximately 1.14 million tonnes of CO2 ― roughly equivalent to one month's amount of CO2 emissions from 2.5 million households.
After then-Prime Minister Junichiro Koizumi was seen working in his shirt-sleeves, the practice became widespread in government and municipal offices, and throughout the political community. There has, however, been some resistance from the private sector. Many corporate business executives such as sales representatives are fighting the Cool Biz trend and feel reluctant to meet customers without wearing ties or jackets.

In Australia, too
Japan's eco-crusade extends well beyond its own borders, with its technology having an impact in many parts of the world, including Australia.
Australia is fortunate in having large reserves of coal, a large percentage of which is used domestically to generate electricity. However, coal-fired power plants emit large amounts of greenhouse gases.
Mitsubishi Heavy Industries (MHI) and Mitsubishi Corporation (MC) announced in June 2009 their participation in a Queensland project to build a low-emission Integrated Gasification Combined Cycle (IGCC) power generation plant with a carbon capture and storage facility.
Together with ZeroGen, a company owned by the Queensland Government, the two Japanese companies will conduct a feasibility study on the project. MHI will be the exclusive manufacturer, supplier and builder of the facility, while MC will co-ordinate the overall project.
This will be the world's first commercial-scale IGCC power plant with carbon capture and storage, generating 530 megawatts of electricity and capturing carbon dioxide (CO2) emissions. The plant is expected to begin operation in 2015.
