In December 2007, for the first time ever, South Koreans, anxious about the economy, elected a businessman as their president. Pro-growth conservative Lee Myung-bak won a resounding victory, with 49 percent of the vote, over left-center candidate Chung Dong-young, who won only 26 percent. Lee's margin would have been even greater had it not been for the late entry into the race by another conservative, Lee Hoi-chang, who finished third with 15 percent.

Korean voters had become tired of ten years of rule by the left-center, and they saw incumbent President Roh Moo-hyun as confrontational and ineffective. By contrast, Lee, a former Hyundai Engineering and Construction CEO, has a reputation for being a pragmatic, can-do leader. As mayor of Seoul (2002-2006), he beautified the city and reformed its mass transit system.

Lee is scheduled to be inaugurated on February 25 for a single five-year term, but he faces two early challenges. First, just before the election, the left-center camp passed a bill establishing a special prosecutor to investigate allegations that Lee had been involved in business fraud and other corruption. The special prosecutor is supposed to announce his findings before the inauguration. A regular prosecutor earlier found the charges to be unfounded, and most observers think that the special prosecutor will not turn up significant new information.

Second, President-elect Lee must counter centrifugal forces in the conservative party ahead of parliamentary elections on April 5. Lee Hoi-chang's defection has already split the conservative camp, and now President-elect Lee and former conservative party leader Park Geun-hye (daughter of the late President Park Chung Hee) are feuding over how much say each should have in choosing candidates for the parliamentary election.

If President-elect Lee is cleared by the special prosecutor and if he successfully manages relations with Park, Lee's party will likely win a very large majority in the parliamentary election, offering him the opportunity to be a strong and effective executive.

As president, Lee will face two long-term challenges. First, as Lee has promised Korean voters, he must strengthen the economy. While the Korean economy has been growing at a rate of about 5 percent in recent years, the average Korean has felt hard-pressed by large increases in housing and education costs. Lee plans to focus on deregulation and attracting foreign investment. He has, however, already been forced to scale back his promise of 7 percent annual growth to 6 percent at least for his first year in office.

Second, although North Korea was not a major issue in the election campaign, due to the apparent progress in Six-Party talks to end North Korea's nuclear weapons program, many experts are skeptical that North Korea will fully abandon its nuclear ambitions. Lee supports engagement of North Korea and continued humanitarian aid, but he has said he will not provide major economic aid to North Korea until it ends its nuclear weapons program. This marks a significant departure from the policy of his predecessors Roh Moo-hyun and Kim Dae-jung. A renewal of tensions with North Korea could threaten South Korean economic growth and Lee's popularity.

Lee strongly supports South Korea's alliance with the United States. He may seek talks with the United States to adjust or delay implementation of agreements reached in recent years to reduce the United States' role in South Korea's defense. Lee also supports early ratification of the U.S.-Korea Free Trade Agreement (FTA), the largest U.S. free trade agreement since NAFTA. (The U.S. Congress has not yet approved the U.S.-Korea FTA.)

Many experts believe that the near coincidence of Lee's election and the inauguration of a new U.S. administration in January 2009 offers a major opportunity to strengthen U.S.-South Korean relations. Shorenstein APARC and the New York-based Korea Society recently announced the formation of a study group of senior former U.S. officials and experts to issue a report and recommendations on how the next U.S. administration can work with President Lee. The study group will travel to Seoul in early February for meetings with President-elect Lee and his economic, foreign policy, and security advisors.

Perhaps the most remarkable aspect of the election of Lee was that Koreans did not think it remarkable. They simply took it for granted that the election would be free, fair, and peaceful. Yet it has only been twenty years since South Koreans literally forced a military-backed government to allow them to vote democratically for their chief executive. In those two decades, there have been five presidential elections, with Lee's victory making the second full-fledged transfer of power between political camps. Moreover, this election was conducted at very low cost, using public funds; companies were not "squeezed" for campaign contributions as in the past. South Korea has demonstrated itself to be, along with Australia and New Zealand, the most democratic country in East Asia and a model of political development for the entire international community.

Japan's ruling party suffered a historic defeat Sunday. For the first time since the conservative Liberal Democratic Party (LDP) was formed in 1955, an opposition party has become the largest party in the upper house.

The powerful message delivered by Japanese voters has significant implications not only for Japan but also for the rest of the world, not least for its close ally, the United States.

The election result revives momentum in Japan toward creation of a viable two-party system, potentially ending the conservative postwar monopoly on power. Japanese voters expressed deep anxiety about the impact of economic change upon their treasured social order. They embraced the campaign of the Democratic Party (the main opposition) against growing income inequality and the failure of the state to take care of an aging population.

Equally important, the vote was a humiliating defeat for Prime Minister Shinzo Abe's agenda of giving priority to revising Japan's antiwar Constitution and allowing its military to take on a global role in support of the US. Democratic Party leader Ichiro Ozawa effectively portrayed Mr. Abe as a man out of touch with the concerns of ordinary Japanese. But he also articulated an alternative vision of Japan's international role, calling for closer ties to its Asian neighbors and sending troops overseas only under the auspices of United Nations peacekeeping missions.

Since 9/11, Japan has been among the most loyal, if not unquestioning, of US allies. It sent troops to Iraq, provided logistical support to the war in Afghanistan, and outdid the US in putting pressure on North Korea. Most recently, Abe echoed the rhetoric of the Bush administration, calling for formation of a "values-based" alliance of democracies along with India and Australia, implicitly aimed at containing a rising China. The election results will certainly slow, if not reverse, this tight synchronization.

For the business community, the vote will raise concerns that needed economic policy actions such as fiscal reforms will get stalled in a gridlocked parliament. The vote reminds politicians that the economic recovery has left an awful lot of Japanese behind, with real wages falling, youth unemployment high, and the elderly drawing down their savings to survive. Abe's feel-good rhetoric and focus on security just angered those Japanese.

There remains strong support for gradual change. Most Japanese want the country to take on a more "normal" security role, but one that will stop far short of overdrawn fears of a remilitarized Japan. And many Japanese, particularly in the younger generation, back economic reform, though not at the expense of social stability.

The most intriguing question is the future of Japan's democracy. Abe is resisting calls for his resignation, attributing the vote to a series of scandals in his Cabinet and most of all to the revelation that the government's national pension system had lost the records of some 50 million people. The election result was bad luck, Abe claimed, not a repudiation of his administration's overall policies -- a view shared by Washington policymakers.

Exit polls do confirm that voters were strongly motivated by these issues. But they also express little faith in the personal leadership of Abe, who tried to cover up the pension debacle. He suffered from an unfavorable comparison to his predecessor, Junichiro Koizumi, one of Japan's most popular postwar leaders.

But the election suggests that Mr. Koizumi's personal charisma only temporarily reversed a longer trend of drift away from the ruling conservatives, particularly by unaffiliated swing voters in Japan's cities and suburbs. Mr. Ozawa, one of Japan's most brilliant politicians, managed to both regain those voters and steal away traditional conservative backers in rural areas among farmers and pensioners worried about their future.

Ozawa, whom I have known for more than two decades, is a man of uncommon political vision. He is a former LDP stalwart who has relentlessly pursued the goal of creating a clearly defined two-party system that can create real competition. He was the architect of a split in the LDP that briefly brought the opposition to power in the early 1990s.

Over dinner last fall, Ozawa laid out to me what seemed then like an incredibly audacious plan to regain power. First to win a series of local elections, leading up to a defeat of the LDP in the upper house election, forcing in turn the dissolution of the lower house and new elections. He clearly hopes to split the LDP again and pry away its coalition partner, the New Komeito Party, as part of his strategy of realignment.

The Democratic Party has yet to demonstrate its own ability to rule, but it would be unwise to underestimate Ozawa. And it would be foolish to dismiss the desire for change delivered by Japanese voters on Sunday.

Almost every facet of modern life - from driving to the grocery store to turning on a light - relies on inexpensive and abundant fossil fuels. When burned for power, these fuels yield emissions of carbon dioxide that accumulate in the atmosphere. They are the leading cause of global warming.

Assuring ample energy services for a growing world economy while protecting the climate will not be simple. The most critical task will be curtailing emissions from coal; it is the most abundant fossil fuel and stands above the others in its carbon effluent. Strong lobbies protect coal in every country where it is used in abundance, and they will block any strategy for protecting the climate that threatens the industry. The only practical approach is to pursue technologies that burn coal much more cleanly.

Such new technologies exist on the drawing board, but governments and regulators are failing to bring designs into practice with deliberate speed. Instead, most of the policy effort to tackle global warming has focused on creating global institutions, such as the Kyoto Protocol, to entice change. Although noble, these global efforts usually fall hostage to the interests of critical countries. After negotiating the Kyoto treaty, for example, the United States refused to sign when it found that it could not easily comply with the provisions. Australia did the same, and Canada is also poised to withdraw. Nor have treaties like Kyoto crafted a viable framework for engaging developing countries; these countries' share of world emissions is rising quickly, yet they are wary of policies that might crimp economic growth.

Breaking the deadlocks that have appeared in the Kyoto process requires, first and foremost, a serious plan by the United States to control its emissions. The United States has a strong historical responsibility for the greenhouse-gas pollution that has accumulated in the atmosphere, but little has been done at the federal level. (A few states are implementing some policies, and they, along with rising political pressure, might help to catalyze a more aggressive federal approach.) It will be difficult, however, for the United States (and other industrial countries) to sustain much effort in cutting emissions unless its economic competitors in China and the other developing countries make some effort as well. Without a strong policy framework to contain emissions throughout the world, levels of greenhouse-gas pollution will reflect only the vagaries in world energy markets. We need a proper strategy for moving away from harmful emissions.

A few years ago, many analysts thought that market forces were already shifting away from coal. They predicted the growth of natural gas, a fuel prized for its cleanliness and flexibility. That vision was good news for the climate because electricity made from natural gas leads to half of the carbon-dioxide emissions of electricity from coal. But natural-gas prices, which tend to track oil prices, have skyrocketed over the past few years, and, unsurprisingly, the vision for the growth of natural has dimmed. Natural-gas plants, which accounted for more than 90 percent of new plants built in the 1990s, are harder to justify in the boardroom. Most analysts now see a surge in the use of coal. One hundred new coal-fired plants are in the planning stages in the United States. Absent an unlikely plunge in gas prices, coal is here to stay.

Despite the challenges of handling coal responsibly, the potential of research and deployment of advanced technologies to help the United States and the major developing countries find common interest on the climate problem is great. In advanced industrialized countries, the vast majority of coal is burned for electricity in large plants managed by professionals - exactly the setting where such technology is usually best applied. In the United States, for example, coal accounts for more than four fifths of all greenhouse-gas emissions from the electricity sector.

Most of the innovative effort in coal is focused on making plants more efficient. Raising the temperature and pressure of steam to a "supercritical" point can yield improvements in efficiency that, all told, can reduce emissions about 20 to 25 percent. Boosting temperature and pressure still again, to "ultra-supercritical" levels, can deliver another slug of efficiency and lower emissions still further. Encouraging investments in this technology is not difficult: most countries and firms are already searching for gains in efficiency that can cut the cost of fuel; a sizeable fraction of new Chinese plants are supercritical; India is a few steps behind, in part because coal is generally cheaper in that country, but even there the first supercritical unit is expected soon. Across the advanced industrialized world, supercritical is the norm, at least for new plants. A few companies are taking further steps, investing in ultra-supercritical units. Two such plants are going up outside Shanghai, using mainly German technology, evidence that the concept of "technology transfer" is becoming meaningless in the parts of the world economy that are tightly integrated. Markets are spreading the best technologies worldwide where their application makes economic sense. In other countries, technologies to gasify coal - which also promise high efficiency - are also being tested.

But power-plant efficiency alone won't account for the necessary deep cuts in emissions. Already the growth in demand for electricity is outstripping the improvements in power plants such that the need for more plants and fuel is rising ever higher, as are emissions. This is spectacularly true in fast-growing China.

A radical redesign of coal plants will be needed if governments want to limit emissions of carbon dioxide. Here, the future is wide open. One track envisions gasifying the coal and collecting the concentrated wastes. Another would use more familiar technologies and separate carbon dioxide from other gases. All approaches require injecting the pollution underground where it is safe from the atmosphere. This is already done at scale in oil and gas production, where injection is used to pressurize fields and boost output. The consequences of injecting the massive quantities of pollution from power plants, however, are another matter. Regulatory systems are not in place or tested, and public acceptance is unknown.

While these technologies can work, they won't be used widely before they progress on two fronts. First, they must become commercially viable. Despite the huge potential of adopting them, it is striking how little money is being spent on advanced coal technologies. The U.S. government has created some financial incentives to build advanced coal plants, but much of that investment is slated for plants that are not actually designed to sequester CO2. In fact, the uncertainty of American policy gives investors in power plants an incentive to build conventional high-carbon technology, because it is more familiar to regulators and bankers. Worse yet, increased emissions today might actually improve a negotiating position in the future when targets for controlling emissions are ratcheted down from whatever is business as usual. Some private firms, such as BP and Xcel, are putting their own money into carbon-free power - but the totality of the private effort is small compared with the size of the problem. There are good mechanisms in place for encouraging public research and private investment in such technologies; the real shortcoming is in the paucity of the effort.

The second problem is that countries such as China, India, and other key developing nations won't spend the extra money to install carbon-free coal. Yet these countries' share of global coal consumption has soared almost 35 percent over the past ten years.

The inescapable conclusion is that the advanced industrialized countries must create a much larger program to test and apply advanced coal technologies. Electricity from plants with sequestration might eventually cost half more than from plants without the technology. That's not free, but it is affordable and is less than the changes in electric rates that many Americans already experience and accept.

State and federal regulators need to create direct incentives - such as a pool of subsidies - to pay the extra cost until the technology is proven and competitive with conventional alternatives. That subsidy, along with strict limits on emissions, will set a path for cutting the carbon from U.S. electricity without eliminating a future for coal. They must also extend the same incentives to the major developing countries, which have no interest in paying higher rates for electricity because their priorities do not rest on controlling CO2. Yet these countries' involvement now is essential. Averting emissions has a global benefit regardless of where the emissions are controlled. And developing countries are especially unlikely to shoulder more of the burden themselves, in the more distant future, unless they are first familiar with the technologies.

Solving the climate problem will be one of the hardest problems for societies to address - it entails complicated and uncertain choices with real costs today, and benefits in the distant future. Yet the stakes are high and the consequences of indecision severe. Serious action must contend with existing political constituencies and aim at existing resources that are most abundant. The technologies needed to make coal viable will not appear automatically. An active policy effort - pursued worldwide and initially financed by the industrialized world - is essential.
