A cancer research charity would not invest in tobacco, it would be unethical. A peace group would not invest in arms. Where you put your money is where you put power, so if we want to create a healthy future we can’t invest in unhealthy things.

Money is a bit like energy, it’s only doing something when it’s flowing, so organisations and banks are constantly investing, and some of that money is going to fund the expansion of fossil fuel drilling. Even if we spend all day campaigning against climate change, our money may be quietly funding climate change. The process of removing money from unethical investments is called divestment.

The campaign for fossil fuel divestment worldwide is Fossil Free, and there are campaigns all over the UK. I spoke with Al about her work on the Fossil Free Oxfordshire campaign.

In Oxford on the 31st of May will be a rally to call for the City Council, the County Council and the universities to divest.
