Thirteenth International Conference on Climate Change: Impacts & Responses

Abstract

Life cycle assessment (LCA) is commonly used for assessing whether your product is green enough. Implementation LCA for upstream, midstream, and downstream activities is not as common as product, but can be used as a primary tool to support decision-making for sustainable development even for oil and gas activities. LCA itself is a comprehensive method to assess direct-indirect environmental impacts across the full life cycle of your activity (drilling, wells, process facility, sales) which naturally allows you to address your organization’s contribution to Sustainability Development Goals (SDGs) 13 (climate action), 14 (life below water), and 15 (life on land). However, we found that LCA can also drive organization to support SDGs number 12 which is responsible of production and consumption by addressing hot-spots (certain area in your system that give the most impact environmentally), which usually come from energy and chemical consumption. By integrating LCA’s recommendation as bottom-up feedback to improve efficiency while protecting environment, and people around, it is sign of sustainable organization regarding the decarbonisation issue, the third phase in LCA is ‘‘Life Cycle Impact Assessment (LCIA)’’ which aims to evaluate the contribution to impact categories such as global warming and acidification. This is valuable input for an organization to determine a decarbonisation plan using a more natural approach such as forestation, cover crop, and aquaculture, or to develop a technological plan such as carbon capture and storage (CCS), carbon demineralisation, and ambient air carbon stripping”
