The American Clean Energy and Security Act of 2009, the House"s cap-and-trade bill, included incentives for power companies to plant trees. To receive such grants, the companies would have needed to partner with non-profit tree planting organizations. The idea was to save consumers money by providing shade to reduce cooling costs and offset carbon emissions. The legislation stated that "shade trees planted in strategic locations can reduce residential cooling costs by as much as 30 percent." But the bill never made it through the Senate and expired at the end of the 111th Congress in early 2011.

We were curious if any other action had been taken to encourage tree planting since the proposed legislation petered out. The short answer is yes, although none as comprehensive as the cap-and-trade bill.

First, it is worth explaining why trees are so important to conservationists in their efforts to combat climate change. All plants absorb carbon dioxide -- a greenhouse gas -- as a part of the photosynthesis process. Carbon dioxide is in turn stored as carbon in the plant"s biomass -- its trunk, roots, and leaves. This storage prevents the carbon from escaping into the atmosphere and contributing to global warming. More plants should mean less carbon dioxide in the atmosphere.

There's plenty of reasons to plant trees for commercial and non-commercial reasons, but the Obama administration wanted to provide additional incentives. So in March 2011, the U.S. Department of Agriculture announced that it would promote the use of wood as a building material. USDA Secretary Tom Vilsack"s strategy specifies that the U.S. Forest Service will choose wood in all of its construction projects. Vilsack also directed the heads of other USDA agencies to adopt this practice. Moreover the Forest Service will conduct research into how to best use "green" building materials like wood.

Vilsack"s program is an effort to meet the requirements that President Obama laid out in Executive Order 13514. This order mandated that all federal agencies will attempt to make environmental improvements and reduce their greenhouse gas emissions. This USDA program may lead to more planting by forest owners, given that there is a slight uptick in demand for wood in construction.

The USDA also promotes tree planting through its Farm Service Agency"s Conservation Reserve Program (CRP). This long-running, voluntary program provides farmers assistance to enact conservation measures on their land. One of the qualifying activities for this assistance is tree planting.

The Food, Conservation, and Energy Act of 2008, more commonly known as the 2008 Farm Bill, also contained provisions to encourage tree planting. Chief among them is the Environmental Quality Incentives Program, which provides landowners -- including those involved in forest production -- with financial assistance to plan and institute conservation practices. The Obama administration, however, can not take credit for this since the last Farm Bill was passed in 2008. It is up for renewal in 2012.

At this time, and for the foreseeable future, the Republican-controlled House of Representatives is unlikely to take up any sort of climate-related legislation. Yet, in the absence of Congressional action, the USDA has taken several actions to incentivize tree planting. That's not the ambitious plan that Obama wanted, but it provides some fulfillment of his campaign pledge. We rate this a Compromise.
