achieve net zero emissions in public buildings and built
infrastructure by 2050; and
WHEREAS, Building and construction contributes 37% of global
emissions for greenhouse gases; and
WHEREAS, Materials such as steel, concrete, asphalt and flat
glass contain high quantities of greenhouse gas emissions due to
the energy-intensive processes used to extract the raw materials
for these products; and
WHEREAS, It is estimated that 75% of global urban
infrastructure that will exist in 2050 has yet to be
constructed; and
WHEREAS, Global emissions can be cut by 70% to 80% through
the use of alternative production materials, industrializing
cement use and optimizing building design; and
WHEREAS, Pennsylvania, as a leader in energy in the United
States, emits nearly 1% of global emissions; and
WHEREAS, The largest emitter of greenhouse gas emissions in
Pennsylvania is the industrial sector, specifically industries
in cement manufacturing, iron and steel production; and
WHEREAS, As part of the Pennsylvania Priority Climate Action
Plan and its goal of industrial decarbonization, the Department
of Environmental Protection plans to support State level buy-
clean initiatives to help grow demand for low-carbon
construction materials in steel and cement; and
WHEREAS, There are many options for sustainable building
materials such as aerated concrete, recycled steel and glass,
reclaimed wood, straw bale, cork, rammed earth, earth blocks and
bamboo; and
WHEREAS, It is important to understand which sustainable
building materials would be suitable for infrastructure in
