Emissions of the powerful greenhouse gas sf6 gas are rising

Energy consumption and production contribute to two-thirds of global emissions, and 81% of the global energy system is still based on fossil fuels, the same percentage as 30 years ago. Plus, improvements in the energy intensity of the global economy (the amount of energy used per unit of economic activity) are slowing.

Climate Change – An Accelerating Global ProblemNuclear Is Low-CarbonAchieving HarmonyThe United Nations recognises climate change as “the most systemic threat to humankind”. Despite this, carbon dioxide emissions related to energy continue to rise – reaching 33.1 billion tonnes in 2018, a record high, and have increased by more than 40% since 2000. The central aim of the 2015 Paris Agreementis to keep the rise in global temperatures to well below 2 °C compared to pre-industrial levels, and with the aim to limit the rise to 1.5 °C. This is driven by the scientific consensus that limiting the rise to 1.5 °C would significantly reduce the risks posed by climate change. Concerted international efforts over the past 20 years have increased the amount of electricity generated by wind, solar and other renewable sources, but have failed to displace fossil fuels from the mix. As a matter of fact, in 2017, fossil fuels produced more electricity – in relative and absolute terms – than ever before.
