Climate change policy can be overwhelming. Here’s a guide to the policies that work.

This article written by David Roberts at Vox is interesting, but it’s kind of long, and most likely will appeal primarily to policy wonks and energy nerds. It summarizes a book with the title, “ Designing Climate Solutions: A Policy Guide for Low-Carbon Energy,” written by Hal Harvey, and also describes a climate/energy policy tool called the “energy policy simulator.” David Roberts also interviews the book author, included in this article.

Some of the infographics are worth a peek. Excerpt from the article:

Climate change is such a large and sprawling problem — there are so many forces involved, so many decision makers at so many levels — that solving it can seem hopelessly complex. There are so many options available to policymakers, each with their own fierce constituencies. Where to begin? Which clean-energy policies actually work?

That is the question Hal Harvey, long-time energy analyst and CEO of the energy policy firm Energy Innovation, set out to answer with a new tool.

The tool is the Energy Policy Simulator, which allows anyone to choose a package of energy policies and immediately see the impact on carbon emissions and other pollutants. (It’s like a video game for energy nerds.) It’s based on a model that attempts to replicate the physical economy, with detailed information about real-world assets.

Using that tool, Harvey and his team narrowed in on the policies that work, the places they work best, and the best way to design them. Their conclusions are summarized in a new book, Designing Climate Solutions: A Policy Guide for Low-Carbon Energy. It’s a compact but detailed how-to guide for developing energy policies that have real impact. (A fairly extensive miniature version of the book is online here, if you want to flip through.)

The results are oddly heartening, or at least clarifying.

For instance: The top 20 carbon emitting countries in the world are responsible for 80 percent of global emissions. Just seven countries emit more than a gigaton annually.

Here is a graph from the book showing, in light blue, the total emissions currently projected for 2050 (it includes the effects of current policies). The colored squares are the sectors where additional policy-driven efforts can reduce emissions enough through 2050 to offer a 50 percent chance of avoiding more than 2 degrees Celsius of global temperature rise. (That is, you will recall, the commonly agreed international target, though many advocate shooting lower, for 1.5 degrees.)
