Constant growth of population is raising the energy demand as well as the environmental impacts and emissions from the use of this energy. To reduce these impacts and emissions, and to conform to the international agreements on climate change, many countries are adopting renewable energy sources for the power supply especially for electric cars. The increasing use of renewable energy and electric cars raises the demand for batteries. The actual goal of reducing the emissions by using renewable energy can only be met if the emissionsfrom battery production are also low. Hence, reduction from battery production is a hugeconcern to actually lessen the environmental impacts. One main concern from battery production is the Global Warming Potential (GWP) of batteries. Reducing the footprint of the inputs that go into the batteries can reduce the overall battery input. The data on metal supply for battery production is required to have a better traceability of emissions, so that the sustainable production of the inputs can take place. This thesis aims to study the environmental impacts of producing nickel sulphate through Lifecycle Assessment using a Parametric Model. Some parameters that have an influence on the production of Nickel sulphate such as Ore grades, Mine-types, Electricity mixes and recovery efficiency from different stages i.e. beneficiation, primary extraction, refining, are chosen as free variables. In addition, the influence of allocation type on the results is also studied. 720 scenarios are formed with the combinations of different values for these six parameters. An inventory for each of the scenario is built that eventually generate 720 results from LCA. The level of influence of ore grade, mine-type, and recovery efficiencies on the GWP is studied for different electricity mixes that correspond to different regions. Ore grade and recovery efficiencies show a negative relation to the GWP for all the electricity mixes. The GWP for underground mine-type is higher than the open cast mine. Influence of Mass and economic allocation on the results are studied with respect to the electricity mixes as well as on different nickel sulphate production stages.
