Europe's plans to cut greenhouse gas emissions, due to be unveiled as part of a radical green agenda this week, risk working against the environment and could destroy the competitive position of European industry, according to the region's leading industrialists.

The warning comes in a letter to Gunter Verheugen, European Union commissioner for enterprise and industry, from Jeroen van der Veer, chief executive of Royal Dutch Shell and chairman of the energy and -climate change working group of the European Roundtable of Industrialists. ERT is a group of about 50 of Europe's biggest industrial companies representing sales of about €1,600bn ($2,300bn, £1,200bn).
