Climate Action Beyond Carbon: Why Sustainable Development Needs a Holistic Approach
How can climate mitigation efforts deliver the greatest benefits not only for the climate, but also for society and the economy? A new study published in Nature Climate Change, co-authored by Abhishek Chaudhary from the ZHAW Zurich Center for Sustainability Leadership, explores how climate mitigation strategies can be designed to support a broader range of sustainable development objectives.
Traditionally, climate mitigation strategies have often prioritised achieving emissions reductions at the lowest possible cost. However, this approach does not necessarily account for the wider social, economic and environmental consequences of different mitigation measures.
In their study "From least-cost to SDG-optimal sectoral allocation of Paris Agreement-compatible mitigation efforts”, published in Nature Climate Change, and co-authored by Abhishek Chaudhary from the ZHAW Zurich Center for Sustainability Leadership, researchers propose an alternative approach that considers how climate action interacts with five key Sustainable Development Goal (SDG) areas: poverty, health, water, the economy and land use.
Their findings show that so-called SDG-balanced portfolios can, in most cases, outperform conventional least-cost approaches across all five indicators while achieving equivalent emissions targets. This highlights the importance of considering synergies and trade-offs between climate mitigation and other sustainable development priorities.
The study offers valuable insights for policymakers and decisionmakers: successful climate strategies should not focus on emissions reductions alone but also consider their broader implications for society and the environment.
