Negative emissions and international climate goals—learning from and about mitigation scenarios

For aiming to keep global warming well-below 2 °C and pursue efforts to limit it to 1.5 °C, as set out in the Paris Agreement, a full-fledged assessment of negative emission technologies (NETs) that remove carbon dioxide from the atmosphere is crucial to inform science-based policy making. With the Paris Agreement in mind, we re-analyse available scenario evidence to understand the roles of NETs in 1.5 °C and 2 °C scenarios and, for the first time, link this to a systematic review of findings in the underlying literature. In line with previous research, we find that keeping warming below 1.5 °C requires a rapid large-scale deployment of NETs, while for 2 °C, we can still limit NET deployment substantially by ratcheting up near-term mitigation ambition. Most recent evidence stresses the importance of future socio-economic conditions in determining the flexibility of NET deployment and suggests opportunities for hedging technology risks by adopting portfolios of NETs. Importantly, our thematic review highlights that there is a much richer set of findings on NETs than commonly reflected upon both in scientific assessments and available reviews. In particular, beyond the common findings on NETs underpinned by dozens of studies around early scale-up, the changing shape of net emission pathways or greater flexibility in the timing of climate policies, there is a suite of “niche and emerging findings”, e.g. around innovation needs and rapid technological change, termination of NETs at the end of the twenty-first century or the impacts of climate change on the effectiveness of NETs that have not been widely appreciated. Future research needs to explore the role of climate damages on NET uptake, better understand the geophysical constraints of NET deployment (e.g. water, geological storage, climate feedbacks), and provide a more systematic assessment of NET portfolios in the context of sustainable development goals.

“…Our 3D geological model is derived from Allenbach et al (2017) and considers nine lithostratigraphic units that have been previously described by Capar et al (2015); Clerc et al (2015) and summarized in the stratigraphic log of Figure 3. The units are divided by lithostratigraphic horizons interpolated in the 3D Geomol static model (Allenbach et al, 2017;Clerc et al, 2015). In addition to the stratigraphic horizons, we also consider the topography of the Geneva Basin (Figure 4).…”

Changes in precipitation rates and the accelerating melting of glaciers due to global warming will strongly affect groundwater resources, whose demand is already expected to increase for the upcoming decades due to demographic growth and urbanization (Mays, 2013). Moreover, these resources may be subject to anthropogenic contamination during well activities (Dragon, 2008;Jasechko et al., 2017). Surface-and groundwater is not only crucial for the development of our society (Velis et al., 2017) but can also play a key role in mitigating the effect of climate change through the development of renewable energies, such as hydropower and geothermal energy (Jialing et al., 2015).Despite their elevated energy potential, high-enthalpy geothermal systems remain under-developed and confined in volcanic areas. In contrast, the development of low-to medium-enthalpy geothermal systems increased significantly over the last decades in suburban regions where the energy needs are the highest (Breede et al., 2013;Olasolo et al., 2016). Additionally, several examples have shown that the energy from medium-enthalpy geothermal systems represents a valuable asset for the reduction of green-house gas emissions while supporting our growing economy (
