Problem:Today’s podcast will explore the application and use of carbon footprint calculations, that is GHG accounting and lifecycle analysis, with Vanja Wylie. In today’s talk, we will discuss, among others, how to GHG accounting can inform decisions on energy efficiency.Key message:Life cycle assessment (LCA) is a systematic, standardised approach to quantifying a product's or system's potential environmental impacts. GHG Accounting is more narrow in its assessment of environmental impacts in that it quantifies the total greenhouse gases produced directly and indirectly from a business or organisation’s activities. Both are increasingly popular among financial and other organisations in making informed decisions on the sustainability of investment portfolios. Data gaps aggravate this and are particularly pertinent in developing countries, but solutions exist. In making decisions on energy efficiency, especially in weighing options, GHG accounting can help take a full lifecycle perspective that accounts not just for energy performance and operational carbon but also material and production carbon intensity and what is referred to as embodied carbon.Speakers: Elisabeth Resch, Vanja Elizabeth WylieSupport: Aristeidis Tsakirishttps://c2e2.unepccc.org/kms_object/informed-decision-making-on-portfolio-decarbonisation-using-ghg-accounting-and-lifecycle-analysis-podcast/
