To address these challenges, Johannesburg\u2019s Development Planning Department is planning to undertake extensive upgrades to this area\u2019s stormwater infrastructure. To do so, however, it needs the climate data developed by the Copernicus Climate Change Service (C3S), which allows for fully assessing the costs and benefits of various alternatives.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\" id=\"block-5df2d28c-719c-42eb-8f4d-56e2800c995a\">The <a rel=\"noreferrer noopener\" href=\"https:\/\/www.iisd.org\/publications\/savi-paterson-park-building-infrastructure-johannesburg\" target=\"_blank\">SAVi assessment<\/a> integrated C3S data to consider a \u201cbaseline situation\u201d against a more traditional, \u201cgrey-engineered\u201d solution, relative to greener alternatives.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The assessment of these alternatives involves:<\/p>\n\n\n\n<ul class=\"wp-block-list\" id=\"block-8e7bb1c5-17fc-4390-9b51-93da7c0381bd\"><li>Calculation of capital and operational expenditures.<\/li><li>Valuation of co-benefits, avoided costs, and societal costs.
