On the 7th November, three of the most inspiring global business stories will be told.

These companies are finding the "holy grail", the link between profitability and Sustainability. And they are entrenching it so deep in core strategy that Sustainability will grow despite the economic condition. It's a great event for people in Strategy, Finance and Operations functions who are looking for commercial opportunities in Sustainability - please forward this email internally as appropriate.

In the run up to the event we will overview each strategy, but here's a summary of why we like them so much:

• Nissan (just confirmed). Its electric vehicle (EV) story may turn into one of the biggest Sustainability strategies of the decade. Back in 2008, CEO Carlos Ghosn was considering population numbers, carbon emissions and oil prices when he put EVs at the heart of Nissan's strategy – much to the surprise of competitors and commentators. Three years on and the bet is looking good - fuel prices have risen, Nissan won the USD1bn New York taxi contract largely thanks to its EV knowledge, and all the major car makers are now investing heavily in their electric programmes.
• Siemens. An excellent example of a "next generation" strategy. The appearance of a CSO on the Executive Board hints that Sustainability is embedded in core business strategy, but the financials tell a much bigger story. Siemens delivered EUR28bn in environmental product revenues in 2010, or 37% of its total revenues. Its sustainable supply chain programme with 1,000 suppliers is outstanding, and Siemens have even set up a bank to finance energy efficiency. We will hear from Kersten via video link directly from the Siemens HQ in Munich. 
• BT. The BT story is a little different. It is about what a small internal team can achieve by focusing on the business case and establishing credibility with the CFO. BT's carbon and energy team has grown from 3 to 28 people in 3 years, and has saved BT over £60m while making a considerable step in reducing BT's emissions intensity. Again, the story is still in its early stages, we will hear from Richard Tarboton how the end game could be a new revenue opportunity for BT.

We will also hear from E&Y, who work on a number of "next generation" programmes. Doug Johnston will share with us what E&Y has found to be the critical ingredients of a successful green change management programme.

Each of these companies is a leader in more conventional elements of Sustainability strategies, such as emissions reduction and measuring their environmental impacts. But at their heart they have a major commercial driver which may be what gives them the X-factor.
