Beyond net zero: Eden's journey to climate positive... by 2030
We’ve joined the Race to Zero – pledging to become a climate positive organisation by 2030.
Carbon is an essential resource and one of the major building blocks for life. The climate problem arises when there is too much ‒ as a gas ‒ in the atmosphere.
Carbon comes in various combinations with oxygen, hydrogen, nitrogen and other elements. These compounds build plants, fungi, microbes and animals – including us and the ‘once living’: such as wood, soil organic matter, peat and limestone (from seashells).
Carbon is what graphite and diamonds are made from (yep, diamonds!)
Carbon combines with oxygen to make carbon dioxide (CO2) and with hydrogen to make methane (CH4). Plants combine the gas carbon dioxide (CO2), with water and sunshine to make energy food (carbs) and life’s building blocks.
No atmospheric CO2 results in average global temperatures of around minus 18˚C (brrr).
Pre-industrial Revolution CO2 levels were around 280 parts per million (ppm). The average global temperature was about 13.6˚C (just right).
Today CO2 levels are 417 ppm and rising. The average global temperature is 15˚C which is getting too hot!
