Concrete is a time-tested construction standby, but the production of the key ingredient, cement, creates a massive amount of CO2 emissions.
Cement manufacturers in recent years have begun to offset cement's high electric and coal-fired consumption with other, bio-based sources. Plants are using from 5% to 20% alternative fuels, for example.
Some cement makers are innovating production to make it more sustainable. For instance, Calera has developed a process to collect 50% of the CO2 emissions from the cement-production process and use it to produce a new type of cement.
Some manufacturers have replaced some of the limestone in the cement mix with supplementary cementitious materials such as fly ash produced from burning coal and unheated limestone. Reducing the amount of heated limestone in the cement reduces the amount of energy needed in production.

EPA Says Additional Lead Paint Cleaning Rules Not Necessary
The EPA has concluded that current Lead: Renovation, Repair, and Painting Program (LRRP) cleaning requirements and lead-safe work regulations are sufficient to protect the public from lead dust hazards. “Our members have been instrumental in contacting legislators to detail the detrimental impact of the current LRRP," says Richard Walker, American Architectural Manufacturers Association’s president and CEO. “This collective industry voice has prompted the EPA to make the responsible decision to refrain from adding further, unnecessary costs to homeowners under the current economic climate."http://www.aamanet.org/news/1/10/0/all/603/aama-commends-its-members-congress-for-vacating-lrrp-clearance-rule
