  • Emissions of the powerful greenhouse gas SF6 are rising

    Jan 21, 2021Energy 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.Landfill mining: is this the next big thing in recyclingDec 04, 2020Which countries emit the most greenhouse gas? | WorldNov 30, 2020Want to cut greenhouse gas emissions?
