Paper - With the recent advancements in concrete technology, design and production of “green concrete” has become desirable. Although, the production of structures that are entirely sustainable is still challenging, industry has shown progress by motivating alternative solutions to conventional concrete such as using recycled aggregates, binary and ternary mixes with high level of supplementary cementitious materials, and alternative binders with different chemistry causing lower carbon footprint than portland cement. However, mix proportioning guidelines for performance-based
specifications have fallen behind these advancements. Despite the well known relation between cement production and carbon dioxide emission, prescriptive-based specifications which set minimum cement content requirement are still commonly used, thereby dramatically impacting sustainability. This paper presents the effect of specifications on sustainability by comparing the corresponding carbon footprint of
cementitious materials required according to the prescriptive and performance-based specifications.
