Here we assess the effectiveness of carbon pricing in reducing emissions using a rigorous, machine-learning assisted systematic review and meta-analysis. Based on 483 effect sizes extracted from 80 causal ex-post evaluations across 21 carbon pricing schemes, we find that introducing a carbon price has yielded immediate and substantial emission reductions for at least 17 of these policies, despite the low level of prices in most instances. Statistically significant emissions reductions range between -5\% to -21\% across the schemes (-4\% to -15\% after correcting for publication bias). Our study highlights critical evidence gaps with regard to dozens of unevaluated carbon pricing schemes and the price elasticity of emissions reductions. More rigorous synthesis of carbon pricing and other climate policies is required across a range of outcomes to advance our understanding of "what works" and accelerate learning on climate solutions in science and policy.}, language = {en} } @misc{MaierWolfKeiligetal.2018, author = {Maier, Philipp and Wolf, J{\"u}rgen and Keilig, Thomas and Krabbe, Alfred and Duffard, Rene and Ortiz, Jose-Luis and Klinkner, Sabine and Lengowski, Michael and M{\"u}ller, Thomas and Lockowandt, Christian and Krockstedt, Christian and Kappelmann, Norbert and Stelzer, Beate and Werner, Klaus and Geier, Stephan and Kalkuhl, Christoph and Rauch, Thomas and Schanz, Thomas and Barnstedt, J{\"u}rgen and Conti, Lauro and Hanke, Lars}, title = {Towards a European Stratospheric Balloon Observatory}, series = {Ground-based and Airborne Telescopes VII}, volume = {10700}, journal = {Ground-based and Airborne Telescopes VII}, publisher = {SPIE-INT Soc Optical Engineering}, address = {Bellingham}, isbn = {978-1-5106-1954-8}, issn = {0277-786X}, doi = {10.1117/12.2319248}, pages = {12}, year = {2018}, abstract = {This paper presents the concept of a community-accessible stratospheric balloon-based observatory that is currently under preparation by a consortium of European research institutes and industry. We present the technical motivation, science case, instrumentation, and a two-stage image stabilization approach of the 0.5-m UV/visible platform. In addition, we briefly describe the novel mid-sized stabilized balloon gondola under design to carry telescopes in the 0.5 to 0.6 m range as well as the currently considered flight option for this platform. Secondly, we outline the scientific and technical motivation for a large balloon-based FIR telescope and the ESBO DS approach towards such an infrastructure.}, language = {en} }
