A UNIVERSITY of York study has claimed pollution levels from efficiency improvements are higher than carbon savings.

Research from the Stockholm Environment Institute, at the university showed a growth in carbon dioxide emissions of 217 Million tonnes (Mt) from increased spending between 1992 and 2004, while more efficient production methods reduced carbon emissions by 148Mt, leaving a shortfall of 69Mt.

The research also showed UK consumer emissions grew by 48.5 per cent between 1992 and 2004, while less carbon-intensive production processes led to a 27 per cent reduction in carbon monoxide emissions throughout the world.

The authors claimed a rise in service-led companies in the UK rather than production-based companies, had helped cut emissions, but these savings led to higher emissions around the world for the production of goods consumed in the UK.
