To amend the Internal Revenue Code of 1986 to provide incentives for carbon sequestration.

SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Combating Climate Change Through 
Individual Action Act of 2008''.

SEC. 2. FINDINGS.

    Congress finds the following:
            (1) Agricultural, grassland, and forestry practices play an 
        essential role in capturing atmospheric carbon and sequestering 
        it as soil organic matter.
            (2) Released carbon can be captured through improved 
        grassland management, tree planting, forest preservation, and 
        enhanced agronomic and irrigation practices.
            (3) Promoting increased natural carbon sinks could have a 
        significant impact on the world's projected carbon emissions 
        from the burning of fossil fuels.
            (4) Certain agricultural and forestry practices can reduce 
        greenhouse gases: (A) avoiding emissions by maintaining 
        existing carbon storage in trees and soils; (B) increasing 
        carbon storage by, e.g., tree planting, conversion from 
        conventional to conservation tillage practices on agricultural 
        lands;
            (5) The large potentials exist through known cropping and 
        land management practices such as adoption of no-till, reduced 
        fallow and use of cover crops, and conservation set-asides with 
        perennial grasses and trees.

SEC. 3. CARBON SEQUESTRATION AND SOIL CONSERVATION CREDIT.

    (a) In General.--Subpart D of part IV of subchapter A of chapter 1 
of the Internal Revenue Code of 1986 (relating to business related 
credits) is amended by adding at the end the following new section:

percent of the qualified carbon sequestration and soil conservation 
expenditures for the taxable year which are paid or incurred with 
respect to the land used in such farming.
    ``(b) Limitation.--The credit allowed with respect to a taxpayer 
under this section for a taxable year shall not exceed an amount equal 
to $10,000, reduced by the sum of the credits allowed with respect to 
the taxpayer under subsection (a) for all preceding taxable years.
