Is the coalition agreement sufficient to reach 1.5 degrees? Where is more action required?

 Speakers will be announced shortly

The aim of this quarter’s BGIS is thus to showcase four important entrepreneurial initiatives. Each can play a major role in reducing and closing the climate finance gap. 

We will ask each of them to present their business plans with significant impact on the world. 

We will then go into break-out sessions to discuss

  1. what is your own background and interest in the field,
  2. what we think about the presentations we just heard,
  3. what is needed to efficiently allocate the €750bn of EU COVID stimulus package, of which €250bn are to support “EU Green Deal” projects
  4. how would you allocate the €250bn,
  5. how would the announced EU-CO2-border-tax impact the “old economy” and the new businesses which presented today

A closing panel of speakers will then discuss the break-out session results.

Background information:

In spite of lots of capital being mobilized by governments to stimulate economies in response to the Corona-crisis, and in spite of a global savings glut which leads to negative interest rates, there is a shortfall of spending on climate-friendly companies and projects. The IEA and IRENA estimate that the “climate finance gap” remains €1.5 trillion a year. This is how much more must be invested per year to limit global warming to 1.5 degrees, as agreed upon in Paris, to avoid a catastrophe. 

In spite of a large number of worthy new companies and plenty of projects which could become “bankable” one day, most capital still goes to finance old CO2-intensive industries with little future. The investments that are needed include risk-capital for venture companies, for project developments and for the roll-out of proven technologies and business models in new markets, including developing and emerging economies. Governments and philanthropical foundations may have to provide seed capital offering preferred returns to private investors to address this market failure. 

Companies such as those presented today help to reduce the size of the climate finance gap either by helping to move capital or by offering profitable technologies which can be scaled globally and reduce the cost of the transition to a net zero emissions economy significantly. 

Learn more about the companies presented on their respective websites:

Let us find ways to cooperate in order to move significant amounts of capital towards climate solutions, in particular into areas perceived as risky, such as project development and scaling-up “green” ventures. Once these are bankable, lots of capital can flow.
