Climate change will re-shape the world: either because we don't address it and the physical environment changes life as we know it, or because we do address it and the way we go about our daily lives is altered forever.
This means that the time has passed when businesses can close their eyes to the issue or deal with it by publishing vague aims in a dusty corner of their website. This issue will change their employees' lives, it will change the regulatory environment in which they operate and in most cases it will change their whole business strategy.
Climate change represents a vital and fundamental challenge to the strategy almost every business is following, and needs the attention of an organisation's leadership.

This is a board issue, said Alastair Morrison, head of client strategy at Pinsent Masons. "You can't have a situation where something like this is outsourced to a department. It has got to be in the consciousness of an organisation."
Companies are increasingly recognising how central an issue this is, and that it requires a response combining strategic thinking, legal and regulatory expertise and a commitment to the difficult business of cultural change. This means that general counsel (GCs) are in an ideal position to provide leadership on this issue.
Morrison said that many GCs are already aware and taking action. "When we look at discussions that we are having with the general counsel community, it is really interesting to see the overall level of awareness and interest in seeking to make a difference. The kind of awareness at a personal level is really high - everybody knows the challenges and issues that we face."
"Very senior legal people have a great degree of influence within an organisation and many of them are really good advocates," he said. "So, armed with a technical knowledge or a good scientific background of the issues, coupled with the knowledge of what is going on within an organisation, one can therefore be using influence in the board, raising consciousness around the issue and seeing what an organisation can do."
The climate crisis
The climate targets set by the Paris Agreement in 2015 aim to keep global temperatures to less than 2°C above pre-industrial levels, and to aim to keep the rise to 1.5°C. We are currently on track for rises of 3°C.
This might not seem much to non-scientists, but the effects are dramatic. The last ice age was caused by a drop in temperatures of only 3.5°C – changes that might seem small to a layperson have a major impact.
We are experiencing the effects of a 1°C increase right now: more hot days, more heatwaves, bush fires in Australia and hard-to-reverse melting of the Antarctica ice shelf.
If we don't arrest the increase then we won't be able to be outside in parts of the world by the end of the century; food prices will increase; coastal flooding will affect 5% of the population and a weakening of ocean circulation will mean more unpredictable and extreme weather.
The role of business
So there is clearly an imperative to act. But should it be down to business to make these changes?
Philippe Joubert believes that it is, not just for society's sake but for the sake of those businesses themselves. Those that do not adapt will struggle to survive and thrive.
Joubert was deputy chief executive of transport and power equipment maker Alstom but left to found and run Earth On Board, which helps companies ensure their strategies take account of the climate crisis.
He said that 2015 – when the Paris Agreement was signed and the Sustainable Development Goals were adopted – was a watershed. After this, directors could no longer claim they didn't know climate was a factor when they made decisions.
"We need to change, and 2015 will certainly be seen as the year where the world has recognised this," he said. "Business is no longer a problem, it should be a solution. Business are certainly at the origin of 70% or 80% of the impact that we have, but business is the only human organisation I know that has the resources, the organisation and the speed of reaction to help us to find a solution. But to be the real solution we should design another business model that is not taking nature for unlimited and granted."
