I recently attended a webinar run by the I.Chem.E. on and the following climate change initiatives post COP22. It finally looks like the engineering institutions are coming together as one, and working with politicians, technologists. This is a critical step in the process as engineers make it happen. There was a lot of debate about carbon credits, and fossil fuel subsidies. Although there is a lot of drive from environmentalists and believers in the political arena, history has shown that significant change ultimately happens when businesses understand the need and buy into it. As one participant mentioned this happened with the behavioural safety culture 30 years ago. Businesses will buy into it, when they see a need for it to sustain their operations. This is where engineers can really get traction, as they are the ones that make things happen at the sharp end. Furthermore, engineers, technologists and operations managers who have a “Lean” mindset will really make it happen. Lean thinking is fundamental to business improvement and long term sustainability. By eliminating “Process” and “Transactional” waste, this saving money alternative forms of low carbon energy can be utilised. The more that low carbon energy is used, the greater the economies of scale, and the greater the long term returns.
