Tara Kannan<br />

Tara Kannan is a first-year MD student at the University of Newcastle. Passionate about<br />

global health, she represents AMSA’s <strong>2017</strong> Code Green portfolio within her university’s<br />

global heath group. She believes that a major way forward in advancing medicine on the<br />

world stage is through nursing our environment back to good health. Aside from that, when<br />

she’s not busy dissecting Guyton’s diagrams, she enjoys perusing news articles online and<br />

loves her Cadbury.<br />

American environmentalist and journalist, Bill<br />

McKibben, offers a simple yet revolutionary proposition<br />

in the climate debate: “Leave oil in the soil, coal in the<br />

hole and gas under the grass”.<br />

The birth of an idea<br />

Divestment is a very simple idea. You just remove your<br />

money from companies that are involved in extracting<br />

fossil fuels. It’s a novel movement in the climate debate<br />

that is different from your traditional change-yourlightbulb<br />

kind of ideas.<br />

Its underlying basis is that to avoid catastrophic<br />

global warming, we will need to reduce our carbon dioxide<br />

emissions. There are three key numbers that explain<br />

this. First, 2˚C is the maximum global temperature rise<br />

this century that is aspired to in the Paris Agreement.[1]<br />

Secondly, we have a ‘carbon budget’ of 565 gigatons<br />

which is essentially the amount of carbon dioxide that<br />

can safely be released into the atmosphere while still<br />

complying to our 2˚C rule.[2] Most importantly, the third<br />

number to know is 2795 gigatons. This is the amount<br />

of carbon dioxide that will be released if all of the<br />

documented fossil fuel reserves<br />

were burned.[2]<br />

Addressing a sixfold rise<br />

in energy demand in the last<br />

50 years, fossil fuels provide<br />

roughly 80% of the energy we<br />

need through coal, gas and oil.[3]<br />

Yet, the money-making industry<br />

releases greenhouse gases into<br />

the atmosphere and thickens Earth’s blanket of air<br />

pollution which led to 3.7 million deaths in 2012 due to<br />

pneumonia, asthma, heart disease, stroke and cancer.<br />

[3] Needless to say, carbon dioxide is a tiny molecule with<br />

a big bite.<br />

So, while as individuals we could make some<br />

adjustments such as changing our lightbulbs and<br />

switching from car use to public transport, if companies<br />

continue to dig up and burn their reserves, these<br />

measures will prove rather insignificant. This is where<br />

divestment comes in - a movement about shifting your<br />

money away from the problem and towards the solution.<br />

Turning back time<br />

In history, divestment has been shown to be a powerful<br />

political tool in several major movements.<br />

In the latter half of the 20th century, a time when South<br />

Africa’s Apartheid was our world’s largest moral issue,<br />

two prominent figures created massive change. Nelson<br />

Mandela and Desmond Tutu suggested a revolutionary<br />

tactic to help counter institutionalised racial segregation<br />

and white supremacy, imploring Western institutions<br />

to cut their economic ties with companies backing<br />

the Apartheid regime. Experts often deem this as the<br />

model of symbolic pressure as it raised awareness and<br />

embarrassed many American businesses.[4]<br />

Then, through the 1990s, a<br />

movement against the tobacco<br />

industry took place to shun the<br />

industry’s negative impacts on<br />

health. Along with regulation and<br />

taxation, tobacco divestment had<br />

a sizeable impact on society,<br />

shrinking the industry and<br />

smoking rates.[4]<br />

Most recently, divestment has had a role in the<br />

Darfur genocide - the first genocide of the 21st century.<br />

Darfur divestment involves removing money away from<br />

companies with ties to the Sudanese government. Some<br />
