Why monitor construction carbons:  Shortly after writing a comment to a linkedin group on the importance of measuring and understanding construction carbons, through tools such as ConstructCO2, indications of increased focus on carbon performance popped up in a tweet (via Julie Urlaub @TaigaCompany ) regarding an Environmental Leader post that referenced Carbon Trust Report: Half of Multinationals to Choose Suppliers Based on CO2 Emissions 

According to the study, a full half of multinational companies plan to select suppliers based on carbon performance, and that 29% of suppliers are likely to lose their places on green supply chains if they do not have adequate performance records on carbon.

In the U.K., 56% of multinationals said that in the future they expect to drop suppliers based upon low carbon performance, with 74% of the U.K. respondents quoting shareholder pressure as a key driver for them in tackling carbon emissions.

And, although the report has a focus on multinationals, it is not irrelevant to the built environment

Next month Marshalls Plc, a supplier of hard landscaping, will be hosting a United Nations Global Compact Supplier event to educate first-tier suppliers on its approach to environmental issues.
