Abstract
Stabilizing global temperature will require a shift to renewable or nuclear power from fossil power and the large-scale deployment of CO2 capture and storage (CCS) for remaining fossil fuel use. Non-climate co-benefits of low-carbon energy technologies, especially reduced mortalities from air pollution and decreased ecosystem damage, have been important arguments for policies to reduce CO2 emissions. Taking into account a wide range of environmental mechanisms and the complex interactions of the supply chains of different technologies, we conducted the first life cycle assessment of potential human health and ecological impacts of a global low-carbon electricity scenario. Our assessment indicates strong human health benefits of low-carbon electricity. For ecosystem quality, there is a significant trade-off between reduced pollution and climate impacts and potentially significant ecological impacts from land use associated with increased biopower utilization. Other renewables, nuclear power and CCS show clear ecological benefits, so that the climate mitigation scenario with a relatively low share of biopower has lower ecosystem impacts than the baseline scenario. Energy policy can maximize co-benefits by supporting other renewable and nuclear power and developing biomass supply from sources with low biodiversity impact.

have you ever wondered whether the environment
consequences of shifting to a low-carbon electricity supply this is a
question that we have tried to answer in our new paper a health benefits ecological threats of low carbon electricity now we go right to the
answers here so the chart shows a comparison of different technologies in terms of the life cycle environmental impacts on human health and on ecosystems up that means we have taking into account the production of the power plants the installation their fuel supply of their operations and the dismantling and what you can see for coal-fired power is that it has the largest environmental impacts gas-fired power plants or for a slightly lower environmental impacts and if you look at most of these environmental impacts due to their actions of climate change that is the greenhouse gas emissions of C U 2 and so on of these power plants other environmental impacts that have taking into account particular matter ozone and toxic pollutants and so on if we look at
the employment of office to capture and storage which is a technology that can substantially reduce the greenhouse gas emissions of fossil-fuel fired plants we see that this offers us a way of lowering the total environmental impacts however it increases the impacts from conventional pollutants in
contrast renewable technologies such as solar power wind power and hydropower has significantly reduced model the greenhouse gas emissions in the climate impact our but also all this other pollutants and some of them by a factor of 10 or so so
energy is Ihsanullah technologies that would be employed by some of the energy scenarios and it has a more mixed picture we see a tradeoff between you reduce greenhouse gas emissions and substantial ecological impacts that would of basically as the associated with the land use the growing of the biomass and with reduced wildlife that results from that process now there's a technology combination which is why we have employed in some of the images in areas which basically the removal of SU 2 from the atmosphere through the employment of bioenergy in combination with suit to capture and storage we see that this has even increased land use impacts which are however offset in part by of the benefit of removing SU 2 from the atmosphere and avoided ecological impact through that this technology also offers a way of of producing health benefits by removing SU 2 from the atmosphere and thereby reducing the greenhouse-gas impacts cost by other energy technologies now if we employ all of those technologies together in an energy scenario we can
see that it offers a way to reduce both human health impacts and ecological impacts by contrast are continuing to employ increasing amounts of fossil fuels but would continue to increase human health impacts and ecological impacts associated with power generation and that's maybe not a good idea
