China and the environment
China’s growing tendency to ignore market forces is working in one surprising field: clean technology. For years China has resisted pressure to control carbon emissions, insisting that it needs to develop first, and that its people could be among the hardest-hit victims of global warming, Beijing has mobilized its resources, as perhaps only China can. With the generous state subsidies, Chinese companies have, for example, taken the lead in solar cell production, and are powering ahead in many other areas. This fall Chinese leaders announced new targets for reducing carbon emissions, which, if met, would put the nation in the lead on combating climate change by 2020.
China has made green technology a national priority, launching major research initiatives on solar-powered batteries and wind technology. Its green stimulus package amounts US$218 billion, the largest in the world, resulting in the founding of dozens of alternative energy companies within the last year.

Budget 2010: New Investments in Transforming America’s Schools and Workforce
In speaking about how to resolve the economic woes facing the nation, President Obama has consistently cited three investment priorities as essential for achieving long-run, sustainable economic growth: clean energy, health care, and education. With respect to the latter, the Metro Program has argued in its Blueprint for American Prosperity initiative that improving the education and skills of American workers would contribute greatly to more robust and widely-shared economic prosperity.
Overall, the President’s 2010 budget envisions a strengthened federal commitment to improving education and enhancing worker skills. Many of the strategies the administration proposes to pursue in this arena could have meaningful impacts in urban and metropolitan communities, though much will depend on how legislation evolves and programs are implemented. Nevertheless, these ideas represent a significant step toward a national economic strategy that invests strategically in human capital to improve our collective prosperity.
