Gazprom has responded by offering price discounts and contract renegotiations, which generated a rebound in its exports in 2013, but 2014 saw a reversion to the new norm with a fall of more than 10% due to warmer weather a further decline in overall European demand. However, a more important trend has emerged in the form of EU legislation and legal activity that has called into question Gazprom's entire activities in Europe. Implementation of the Third Energy Package has effectively caused the cancellation of the South Stream gas pipeline and blocked full use of the OPAL pipeline in Germany, despite the fact that the legislation has yet to be fully sanctioned, while EU Competition Authority investigations into Gazprom's business practices in a number of Central and Eastern European countries have raised questions about oil-linked gas pricing and anti-competitive behaviour. Gazprom's response has the potential to radically alter its export strategy.
