At it’s core, Earth: The Sequel is an argument for cap-and-trade as a viable, market-based mechanism for addressing climate change. While long-time sustainablog readers are likely up on the concept of cap-and-trade, it’s worth a quick explanation. Krupp and Horn define the concept in the book’s first chapter:

The U.S. Congress must set a legal and steadily declining limit on global warming pollution. The allowances will be divvied up among emitters, or auctioned by the government to raise revenues — or some combination of the two. Polluters who emit more will need to pay for the extra pollution reduction achieved by others; those who can reduce global warming pollution further will profit by selling those reductions in an open market. We can, in short, use the power of the market system to climb out of the hole created by flawed markets.

One might worry that what follows such an introductory chapter might be a long, boring treatise on market-based economics and the environment; rather, the bulk of the book focuses on the companies (mostly start-ups) involved in innovative research and development of next-generation clean energy technologies. I’ll be discussing some of those stories in subsequent posts at CleanTechnica and Ecopreneurist. Today, I want to stay focused on this main argument: cap-and-trade is the mostly viable method of achieving significant reductions in greenhouse gas emissions.
