Most, if not all, of the observed increase in the global average temperature since the middle of the 20th century has been a result of the increase in anthropogenic GHG concentrations, and the increased consumption of fossil fuels has had a direct impact on this. [...] This is important to remind, in the context of global responsibility, capacity to act, and financial capability to invest and support poorer countries in deep decarbonisation efforts, and that about 40% of CO2 remains in the atmosphere for longer than 1,000 years. [...] While the technology pathways suggested are clearly ambitious, it outlines the steps that would be required, with defined five-year milestones, to achieve the target of decarbonization of global energy systems through 100% renewables and improvements in efficiency, without having to resort to the use of nuclear power, and fossil-fuel based power combined with CCS and BECCS. [...] As per their modelling, the share of RE in electricity generation will have to move from the current level 21% in 2020 to 56% in 2030, and 100% by 2050, and all energy use that is presently still fossil fuel- dominated (oil and gas) is run by renewables, including synthetic fuels and hydrogen as energy carriers. [...] Renewable Energy for energy equity and justice Despite significant progress in ensuring energy access, with the number of people without access to electricity declining from 1.2 billion in 2010 to less than 760 million in 2019, about 660 million people might still lack access to reliable electricity in 2030 in the absence of early action and adequate financing.
