This voluntarily set goal is regarded as very challenging since Korean industry doubled its greenhouse gas emissions between 1990 and 2005, the fastest growth in the OECD. With this pledge, Korea seeks to be a model for other countries, such as China and India, which are categorised as developing countries under the Kyoto Protocol; these countries have no binding obligation except to announce their reduction target by 2030.

The company has launched a rotor turbine of improved efficiency, which is unlike any other in the world. The design has the working title LEK. The LEK design, in both theory and practice, significantly increases the amount of energy extracted from the wind by using a new design concept. All rights to this invention belong to SIA Latekols and are protected by national patents in 60 countries.

It delivered a decision support system (DSS) tool using geographical information system (GIS) software. This tool is available on the internet. During the EWEA annual event (formerly known as EWEC), held in Brussels on the 14–17 March 2011, key results of this project, and a roadmap for the roll-out of wind energy in the North Sea, were presented.

Shepherd Advisors examines this flow of products and services from a different angle – what we call the ‘buy chain’. We seek to understand what drives buying decisions at various links in the chain from raw materials to finished product. Our aim is to gain more robust knowledge of ‘Who is buying what?’, ‘Why are they buying?’ and ‘How they are buying?’ In other words, we are interested in the circumstances surrounding buyers’ purchase decisions, and the key factors driving them.
