Net-Zero Action Recommendations for Scope 3 Emission Mitigation Using Life Cycle Assessment

Greenhouse gas emissions anywhere across the value chain cause the global temperature to rise. A responsible net-zero strategy is reducing and removing direct and indirect greenhouse gas emissions. The current net-zero actions aim to offset rather than reduce or remove life cycle greenhouse gas emissions (GHG). Unless the demands/consumptions are reduced, net-zero actions will merely be a burden-shifting practice.
Scope 3 emissions are considered in the life cycle assessment (LCA) of goods and services and account for direct and indirect emissions with imported goods and services. Scope 3 emission tariff seems an effective way to shift consumption patterns to carbon-neutral options.
This article explores tools and systems for ‘just transition’ using three buckets of scientific questions: (1) Technical: which GHG to remove, when, where, and by what mechanism; (2) Social-Policy: how to share GHG obligations between stakeholders to deliver the UN SDGs; (3) Data: how to create robust, trusted, and transparent data for reporting, accounting, and actions. Building on the analyses, this study recommends thirteen scientific evidence-based net-zero actions.

Covid-19 and a Just Transition in India's Coal Mining Sector
The COVID 19 pandemic hit India hard in early 2020, with negative GDP growth and a surge in unemployment. In the energy sector, coal fired power generation was already under pressure from overcapacity, low electricity demand growth, and increasingly competitive renewables.
Considerations for a Just and Equitable Energy Transition
As the energy transition accelerates, it is our responsibility, it is our opportunity, to ensure that in addition to contributing to a healthy planet by replacing fossil fuels with clean energy sources, this is accomplished in a just and equitable manner providing prosperity for all.
