California and carbon

So California is taking the American lead in trying to do something about global warming. Pretty dang cool.
California will become the first state in the country to require industries to lower greenhouse gas emissions under a deal struck Wednesday by Gov. Arnold Schwarzenegger and Democrats that could dramatically reshape the state’s economy…. By 2020, when industries would have to lower carbon dioxide and other greenhouse gases by 25 percent, solar panels, alternative fuels and electric cars could be commonplace, according to advocates of the legislation.
The plan is to use tradable emission permits, at least tentatively.
The board is likely to set up a trading system that will allow companies to buy and sell emission credits, which would allow a company that made more emission reductions than required to sell credits to another business that hasn’t reached its emission goal…. The governor also demanded that the bill require that a trading system be created to help industries meet the targets. While the final version of the legislation points the way toward a trading system, some argued it was not specifically required and that the governor did not get what he wanted. British Petroleum announced late Wednesday it would not support the bill because it seemed unclear as to whether a trading system would actually develop.
So first thing to do is say, “yahoo! Some good news!” The next thing to do is be wary of a cap-and-trade system for carbon. Cap-and-trade can work quite well in reducing pollution, as is evidenced in the experience of sulphur and nitrogen oxides. However, to work, a system like this needs to have measurable emissions. For sulpher dioxide, the emissions were mostly coming from large industrial facilities, especially coal-fired electricity power plants. It was pretty easy to put a meter on the smokestack to measure how much SO2 was coming out, and then check to see if the facility had the necessary permits to cover their emissions. But carbon doesn’t strike me as easy to enforce. I suppose for large facilities burning fossil fuels, they can submit records of their coal, oil, and natural gas purchases, and those numbers can be converted into estimated carbon emissions. You can’t do that for transportation, though, at least no way that I can think of off the bat. Maybe California will ignore transportation. Anyway, we’ll see. PS: Broken Flowers is a great movie. Oddball and funny. One of Jim Jarmusch’s best.

Overshoot, Collapse, and Creating a Better Future

In 2016, Earth Overshoot Day happened on August 8—the day when we’ve exhausted the planet’s resources for the year, and are essentially borrowing from future years to maintain our existence today.Perhaps you celebrated this day with a counter-solution: a vegetarian meal, telecommuted, or turned off the air conditioning. There’s a lot more you could be […] Read More

Save Energy & Money This Winter: Seal Up Your Drafty House

Unless you’ve taken special preventative precautions, it’s likely that on cold days much of your house’s heat pours out through your (closed) windows. Most houses—especially old houses—have drafty, uninsulated windows that do little to prevent heat from dumping out into the cold night. Even if your windows aren’t drafty, the expensive heat your furnace has […] Read More

The Limits to Growth and Greece: Systemic or Financial Collapse?

Could it be that the ongoing Greek collapse is a symptom of the more general collapse that the Limits to Growth model generates for the first two decades of the 21st century? Author Ugo Bardi (Extracted: How the Quest for Mineral Wealth is Plundering the Planet) examines the correlation between what is unfolding between Greece […] Read More

Designing Your Own Solar Cooker & Dehydrator

In today’s world, nearly everything we use, from phones and computers to cars and kitchen appliances, requires energy derived from fossil fuels. Wouldn’t it be nice to offset some of that energy use by harnessing the renewable power of the sun? Josh Trought, founder of D Acres—an educational center in New Hampshire that researches, applies, […] Read More
