The world has witnessed significant change since the dawn of the industrial revolution. Life expectancy has more than doubled; travel across the planet can happen in less than a day; loved ones can be reached via a video screen and vast quantities of information can be accessed at the touch of a button. But as our quality of life, and the science and technology that has facilitated this, has improved, so too has our impact on the earth’s biosphere become more pronounced. Greenhouse gas (GHG) emissions in the earth’s atmosphere – seven of which contribute to climate change, including carbon dioxide (CO2), methane (CH4,), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), hexafluoride (SF6), and nitrogen trifluoride (NF3) – have grown exponentially since the 1970s leading to a range of pernicious ecological, physical and health impacts.
For decades, scientists and activists have warned of the dire consequences awaiting the world if action to reduce GHG emissions is not taken. Catalysed by a growing number of extreme weather events alongside a strong wave of environmental activism, the majority of consumers, industries and governments have come to the consensus that action towards becoming environmentally sustainable must be taken.
