How Not to Manage Risk

Today’s post is by Jon Anda. He is President of the Environmental Markets Network, an organization within Environmental Defense focused on legislation to create an efficient carbon market.

Bjorn Lomborg, who wrote the infamous “The Skeptical Environmentalist,” has a book coming out this fall called “Cool It.” He says we should spend minimal resources to fight global warming.

I wrote a guest post for Grist yesterday about why his approach is wrong. Here’s a key point from it:

Lomborg’s preference is to leave future generations more cash and less technology. Our grandchildren can easily go back to burning coal if climate turns out to be manageable. But how easily can they spend the extra cash if the Greenland ice sheet is irreversibly melting?

And here’s the whole post.

Ensuring Carbon Offsets are Real

The author of today’s post, Sheryl Canter, is an Online Writer and Editorial Manager at Environmental Defense.

Carbon offsets are a good idea that, unfortunately, without guidelines, can be implemented badly. The basic idea is to reduce and then offset the carbon emissions produced by your lifestyle by funding projects that reduce carbon emissions elsewhere. This works because, from a global warming perspective, it doesn’t matter where the carbon comes from. A reduction anywhere reduces the global total.

But how do you know a given offset is truly reducing carbon emissions?

Why does the "safety valve" matter to farmers?

Today’s post is from Sara Hessenflow Harper, a policy analyst for our national climate campaign. She does extensive outreach to the agricultural community.

Yesterday, Mark MacLeod wrote about the “safety valve” and its flaws. I wanted to add to the discussion a more specific look at its implications for rural America. In addition to the problems Mark noted, the “safety valve” would also cut farmers out of the carbon market. Here’s how.

What is the "safety valve"?

Today’s post is by Mark MacLeod, director of special projects for the national climate campaign at Environmental Defense.

Some people have proposed a “safety valve” to control the costs of a cap-and-trade policy to fight global warming. This post explains what a safety valve is, and why it provides only an illusion of cost management.

How does cap and trade work?

This post is by Mark MacLeod, director of special projects for the national climate campaign at Environmental Defense.

Cap-and-trade is the structure of most of the global warming bills being considered by Congress.

The “cap” is the cornerstone of the policy. It is an absolute, nationwide limit on global warming pollution. Congress would most likely establish a cap measured as billions of tons of carbon dioxide (or equivalent) released into the atmosphere each year. Over time, the cap would be lowered to cut emissions enough to avoid the worst consequences of global warming. (See our earlier series for more on how much we need to cut.)

The “trade” part is a market that creates powerful incentives for companies to reduce pollution, and provides flexibility in how companies can meet the limits.

Here’s how it works:

What is a Carbon Footprint?

You hear a lot of talk these days about "carbon footprints". But what is a carbon footprint, anyway?

Carbon dioxide (CO2), while not the only greenhouse gas, is the most abundant. CO2 is emitted into the atmosphere when we burn fossil fuels, and most of the energy in this country comes from burning fossil fuels. Thus, anything that requires energy to manufacture, transport, or operate causes the emission of CO2 (see my previous post, The Carbon Footprint of… Everything).

A "carbon footprint" is the amount of CO2 released by an activity or entity. So what’s your carbon footprint?
