The Energy Savings Opportunity Scheme (ESOS) regulation requires large companies to calculate and measure their energy over 12 months with 90% of the energy audited before the end of 2015.

Use our carbon reporting portal that will enable you to upload your energy usage to our sophisticated system which will calculate all data based on the DEFRA conversion factors, giving you a breakdown of your energy usage.

Desmond Clark (1979:7) observed that without radiocarbon dating "we would still be foundering in a sea of imprecisions sometime bred of inspired guesswork but more often of imaginative speculation." And as Colin Renfrew (1973) aptly noted over 30 years ago, the "Radiocarbon Revolution" transformed how archaeologists could interpret the past and track cultural changes through a period in human history where we see among other things the massive migration of peoples settling virtually every major region of the world, the transition from hunting and gathering to more intensive forms of food production, and the rise of city-states.

However, as with any dating technique there are limits to the kinds of things that can be satisfactorily dated, levels of precision and accuracy, age range constraints, and different levels of susceptibility to contamination.

Compared to conventional radiocarbon techniques such as Libby's solid carbon counting, the gas counting method popular in the mid-1950s, or liquid scintillation (LS) counting, AMS permitted the dating of much smaller sized samples with even greater precision.

Regardless of the particular 14C technique used, the value of this tool for archaeology has clearly been appreciated.

Researchers have demonstrated a new compact spectroscopic instrument that offers a highly sensitive optical method for detecting radiocarbon dioxide concentration, which can be used to carbon date fossils and archaeological artifacts.

A new spectroscopic technique offers ultra-sensitive optical detection of radiocarbon dioxide.The SUERC Radiocarbon Laboratory is involved in archaeological, forensic and environmental research, additionally using stable isotopes (13C and 15N) for dietary reconstruction.As well as undertaking its own in-house and collaborative research, the SUERC Radiocarbon Laboratory also provides a radiocarbon dating service to national and international museums, universities and archaeology units.However when they die the radiocarbon decays and is not replaced.Since it decays at a known constant rate, the decreasing concentration of 14C can be measured and the date when the material died estimated.The reporting portal is very user friendly with the category tabs allowing for easy navigation when inputting data.
