California's Global-Warming Solution

After dinner one recent night, family an friends were discussing their views on global warming. With clarity and wisdom beyond her 15 years, my daughter said, "Dad, I'm scared and angry. Your generation created this problem. What are you going to do to fix it?"

California's legislators rolled up their sleeves last week and got started on an answer, passing the most important legislation of the year, possibly of the decade: the California Global Warming Solutions Act. With any luck, its cooling effects will be felt for the rest of the century--and beyond.


Though confronted with a growing climate crisis, the nation has struggled to find scalable, society-wide solutions--and the political will to enact them. When seven Northeastern states capped emissions of greenhouse gases by utilities last month, we took a giant step forward. But until last week, no American state had been bold enough to approve legislation that caps emissions across all the meaningful economic sectors. California--where 1 of 8 Americans lives--will now require major industrial producers of such gases to reduce emissions 25% by 2020. That means cutting the annual release of carbon dioxide in the state by 174 million metric tons. It takes a forest twice the size of New Jersey to process that much of the heat-trapping gas.


How will we achieve that? By letting free markets discover the best solutions and invest in them. Create a market for carbon removal, and set limits on companies' allowance for carbon emissions. Companies that pollute less get credits and can then sell those credits to other companies, who buy them to offset their excess carbon. A similar market system for sulfur dioxide is already in place to cut sulfur pollution in half by 2010, dramatically reducing acid rain.


That "cap-and-trade" approach works because it provides certainty--companies have a specific greenhouse-gas-emission target--and because free markets are the most efficient way to reward innovation. A market-based system has two added benefits: it creates new revenue sources for companies clean enough to sell credits, and it enables free markets to determine the best solutions instead of having governments bet on what they think are going to be the winning innovations. That vision is one reason a Republican Governor and a Democratic legislature were able to agree on the global-warming act and many business leaders--including Silicon Valley entrepreneur turned environmental activist Bob Epstein--got behind it.


The economic benefits are large and calculable. In California, the world's sixth largest economy, the Climate Action Team determined that global-warming reduction would increase income by more than $4 billion while providing 83,000 new jobs. Growth will come from several sources: innovative green technologies will create high-quality jobs and new revenue streams. In addition, companies will have increased purchasing power once they decrease energy costs and reduce imports of fossil fuels. The notion that businesses will leave the state is flawed because all suppliers that sell to California are affected, not only California-based suppliers. The doomsayers just don't get it: we can harmonize economic growth and environmental benefits.
