Building with Cob

Cob is an ancient and simple building material. Made of soil, sand, straw and water, it can last for decades, sometimes centuries, and is an inexpensive, local, green building material.

The Cob Builders Handbook says,

“The three most common forms of earth buildings are adobe, rammed earth and cob. In the southwestern United States, the five hundred year old Taos Pueblo, as well as many homes and churches, are made of adobe. Adobe is a form of building using unfired earth. Dirt, straw and water - the same ingredients as in cob - are made into bricks which are then sun dried and built into walls with a “cob-like” mortar. Some very old Native American structures like the Casa Grande ruin in Arizona are made out of cob. These are described locally as being built of “puddled or coursed adobe”.”

This spring, Green-Trust will be building a generator and wood boiler shed with cob, in preparation for building a few homes as well.

Offset your Automobile, Home, & Flight Emissions

What is TerraPass?

Ever wished you could do something about global warming?
It might seem there’s nothing you can do about global warming. The problem is just too big.

Of course, we all contribute to global warming. We all have a “carbon footprint,” the total carbon dioxide emissions we create when we drive or fly or use electricity.

Eliminate your carbon footprint with TerraPass
The first step you can take to fight global warming is to reduce your carbon footprint through conservation. Drive less. Turn down the thermostat. Buy locally produced goods.

Then use TerraPass to reduce your carbon footprint all the way to zero.

When you buy a TerraPass, your money funds renewable energy projects such as wind farms. These projects result in verified reductions in greenhouse gas pollution. And these reductions counterbalance your own emissions.

A new kind of environmental movement
Of course, global warming is too big a problem for a handful of people to solve on their own. It’s a global problem that requires action on a global scale.

But entrepreneurial groups are leading the way. City and state governments, forward-looking businesses, and enthusiastic citizens are banding together to show that a sustainable future is possible today.

Every TerraPass member has taken a simple positive step to fight global warming. Every TerraPass purchase is a vote for innovation, efficiency, and clean energy. Together, we have eliminated over 150 million pounds of carbon dioxide emissions.

Be part of a group that is driving change today.
