3. NbS in Net-Zero: avoiding greenwashing & supporting the SDGs

This session will start by reviewing the potential of NbS to support climate change mitigation, clarifying the scientific basis that NbS require fossil fuels to be kept in the ground. It will then directly address current criticisms that NbS are being used for greenwashing, including what the evidence for this is and how it is being done, as well as exploring how this can be avoided. Discussions will broach whether and how NbS can and should play a role in achieving net-zero and be used in offsetting schemes and, if so, how we ensure the price is high enough to avoid cascades of negative impacts on people, climate and nature. The discussion will also include the possibility of using net-zero momentum as a window of opportunity to scale up NbS projects, and discussion of insetting as an alternative to offsetting. We will ask how to ethically and sustainably bridge the divide between the public and private sectors on NbS and why we need to.

    Steve Smith

    Executive Director, Oxford Net Zero and CO2RE

    Steve's research interests lie at the intersection of climate science and policy. He has published on a range of topics including metrics for comparing emissions of different greenhouse gases, and the governance of carbon dioxide removal. He is co-developer of the Net Zero Tracker, a major global stocktake of net zero pledges. Steve is based at the Smith School of Enterprise and the Environment at the University of Oxford. There he directs two research programmes: Oxford Net Zero and CO2RE. He has a PhD in atmospheric physics from Imperial College London, and worked previously at the UK Climate Change Committee and in government.

    The role of NbS in Brazil’s net zero pathways

    Aline Soterroni is a Research Fellow at Oxford Net Zero and the Nature-based Solutions Initiative, where she investigates the socioeconomic and ecological outcomes of different pathways to net zero. Aline is interested in understanding the timeframes and spatial scales over which restoration, protection and sustainable management of working lands can enhance carbon stocks and reduce GHG emissions whilst supporting biodiversity, human adaptation to climate change and food security.
