Fracking is the method which has been primarily responsible for the explosive growth of fossil fuel extraction in the West Texas shale oil and natural gas deposits. This has resulted in a tremendous increase of fossil fuel exports from the Port of Corpus Christi and also in the current and planned build-out of petrochemical plants and shipping facilities in the Coastal Bend area.

The following are some excerpts from https://www.sierraclub.org/policy/energy/fracking which highlight very clearly the stated policies of the Sierra Club that totally oppose fracking:

Definition. Hydraulic fracturing, or “fracking,” refers to the process of extracting natural gas and/or oil from tight rock formations below the surface using fluids, gases, chemicals, and proppants at high pressure to break apart and release hydrocarbons present in the rock. This includes activities ancillary to this process such as lateral or non-linear drilling, wastewater storage, and other well stimulation methods such as acidization.

Statement of Policy.  The Sierra Club opposes the use of hydraulic fracturing (fracking).

Rationale. There are no “clean” fossil fuels. The Sierra Club is committed to eliminating the use of fossil fuels, including coal, natural gas and oil, as soon as possible. We must replace all fossil fuels with clean renewable energy, efficiency and conservation.Fracking poses unacceptable risks to our communities, our environment and our climate.
