Climate change is recognised as a considerable threat to the stability of the global economy. Efforts are underway internationally, andin South Africa, to reduce the use of fossil fuels and to develop initiatives that reduce emissions of greenhouse gases. Individual companies are coming under increasing pressure from both shareholders and customers to play an active role in reducing the carbon footprint of their operations and products
Life cycle assessment (LCA) is a tool to undertake a systematic environmental assessment of product supply chains. It aims to reveal and quantify environmental impacts and resource use along the complete supply chain of a product or service, that is, from the mining and extraction of its raw materials, to the manufacturing, distribution and use of
Sustainability metrics & indicators
The Green House excels at quantifying and measuring sustainability performance. This core area of work extends to developing sector- and client-specific sustainability metrics and indicators for ongoing monitoring and improvement.
Water is an increasingly important strategic and environmental issue globally and is particularly relevant in South Africa, where heightened awareness, tighter regulation and limited availability are driving interest in understanding all forms of water use along supply chains.
A water footprint, analogous to a carbon footprint, reflects the total amount of water used in the supply chain of a product or service and therefore gives a more meaningful measure for comparing products’ water impacts than just the direct water use of the final manufacturing stage, or that incurred during use of the product.
In addition to conducting water footprints, The Green House can assist companies with reporting in line with the CDP’s Water Disclosure Project.
Ecological footprinting is a methodology that developed out of the recognition that the planet is finite and that our demand for natural capital is greater than the regenerative capacity of the planet. Ecological Footprints measure the impact of human demand for resources and our contribution to the generation of waste. This indicator provides a lens through which to see how our collective decisions impact the local and global ecology. Using the common unit of land area required per capita, Ecological Footprints represent a partial measure of the extent to which individuals, communities, cities, individual countries and the planet as a whole are moving towards sustainability.
The Green House has experience in both top-down and bottom-up calculation of ecological footprints for different spatial scales. The Footprint Network’s South African ecological footprint calculator was developed with input from The Green House.
