Coal is a toxic substance.
Coal mining and burning has poisoned ecosystems, destroyed precious landscapes, and killed millions since the industrial revolution. Acting now will save lives.
These are the key reports and studies that show the human costs of coal.
Lost towns, cultures and ecosystems
Anyone who has seen the film Anthropocene will have gasped at the sight of an entire town being destroyed to make way for a vast coal mine. To enable coal mining farms, forests and towns are devastated, and sometimes entire mountains removed, poisoning the headwaters of rivers and burdening nearby communities with noise, pollution and illness. Lives and connections to land are shattered, as the Wayuu of northern Colombia understand. The National Geographic and Undark articles are a glimpse into this pain.
In 2011 a huge block of India’s biodiverse Hasdeo Arand forest in Chhattisgarh was destroyed for coal mining, which continued despite court challenges. Now, against widespread community opposition, the Modi government is forcing an auction of 40 more blocks of the forest for new private sector mines. 6000 people and 5 villages will be displaced, and thousands of hectares of irreplaceable forest habitat destroyed.
The rehabilitation of mines is costly and challenging, and cannot reverse the toxification of rivers, air and ecosystems during the mine’s life, or replace the lost animals and ways of life.
Communities also face other risks.
In February 2014 the brown coal pit at the Hazelwood coal mine in Australia’s Latrobe valley caught fire during a bushfire. It burned for 45 days, blanketing the town of Morwell and nearby areas in toxic smoke and ash. The fire caused elevated levels of PM2.5 and benzene pollution, with long-term risk of respiratory conditions, heart attack, stroke and lung cancer, long-term cognitive decline and psychosocial effects. The operator was later found guilty of ten offences relating to pollution from the fire and neglect of the mine’s safety and fire fighting protocols, and the Victorian government commissioned an official Inquiry.
Millions of lives lost - but could they be saved?
Coal kills because it is toxic - it contains a cocktail of heavy metals that poisons both the lungs of miners and the rivers that sustain us - and because its burning fills the air with tiny PM2.5 particles that lodge deep in our lungs, causing neurological damage, respiratory illness and cancer.
The studies below paint a frightening picture of how lethal coal and other fossil fuels are. Boston’s Health Effects Institute estimated that in 2016 worldwide exposure to PM2.5 contributed to 4.1 million premature deaths and household air pollution contributed to another 2.6 million deaths. In 2013, Chinese and American researchers established that burning coal has the worst health impact of any source of air pollution in China and caused 366,000 premature deaths.
An Indian study found that 80-120,000 deaths are caused by coal-related emissions, along with 20 million new diagnoses of asthma and an estimated cost of $3.3-$4.6 billion each year in hospitals and health spending.
However, the benefits of moving beyond coal and phasing out all fossil fuel emissions will be enormous. The Nature Climate Change Study estimates that the human health benefits of increasing 21st-century CO2 reductions by 180 GtC leads to 153 ± 43 million fewer premature deaths worldwide, with ~40% occurring during the next 40 years. More than a million premature deaths would be prevented in many metropolitan areas in Asia and Africa.
