The production of concrete and cement (one of the key ingredients in concrete) is highly energy-intensive. Its processing and transport consumes a lot of energy, which means the concrete industry as a whole emits high levels of CO2 and other greenhouse gases. However, since concrete is a fairly resilient and long-lasting product, longevity should also be taken into any considerations of the environmental impact of concrete production and use.
Concrete is the most common construction material in the world, and, in fact, is the second most-consumed product after water! CO2 emissions are the major problem with concrete, since for every ton of concrete produced, a ton of CO2 is emitted, both from the energy required and from the decomposition of the limestone. Nitrous oxide and particulate matter are also emitted in the process. The benefits, as sfazeli38 noted, are that concrete is low-maintenance and that building a concrete production center consumes little energy compared to glass, plastic, aluminum and steel production.
