• Publication 7 December 2022 Modeling global and regional potentials for building-integrated solar energy generation With the Paris Agreement coming into force, global efforts will need to maximize opportunities through energy efficiency and renewable energy generation. Zero energy/carbon initiatives are mushrooming worldwide, but it has not been fully understood which building types in which climates and under which conditions can potentially be built to net zero energy standards. In order to inform these efforts, a new model was developed to estimate the technical potential for building—integrated solar…
• Publication 7 December 2022 Organizing collective action: Does information and communication technology matter? In recent years, there have been significant changes in the fields of collective action and political activism. The increasing use of ICTs in social interactions has facilitated informal ways of organizing and affected the participation, emergence, and organizing of conflictual and consensual collective actions. In this study we seek to understand how the integrated use of multiple ICTs, that is the ICT ensemble, affects the organizing of consensual collective action. We investigated the ICT…
• Publication 7 December 2022 Nitrogen turnover and N2O/N2 ratio of three contrasting tropical soils amended with biochar Biochar has been reported to reduce emission of nitrous oxide (N2O) from soils, but the mechanisms responsible remain fragmentary. For example, it is unclear how biochar effects on N2O emissions are mediated through biochar effects on soil gross N turnover rates. Hence, we conducted an incubation study with three contrasting agricultural soils from Kenya (an Acrisol cultivated for 10-years (Acrisol10); an Acrisol cultivated for over 100-years (Acrisol100); a Ferralsol cultivated for over 100…
• Publication 7 December 2022 Sustainability labelling as a tool for reporting the sustainable development impacts of climate actions relevant to Article 6 of the Paris Agreement The architecture of global carbon markets has changed significantly since the Paris Agreement and the 2030 Agenda for Sustainable Development Goals were both agreed in 2015. Voluntary, international cooperative approaches established in Article 6 of the Paris Agreement allow Parties to work together to achieve the targets set out in their respective Nationally Determined Contributions to limit global warming to an increase below 1.5–2 °C. In Article 6.4, a sustainable mitigation mechanism…
• Publication 7 December 2022 Ammonia and nitrous oxide emissions from a field Ultisol amended with tithonia green manure, urea, and biochar Short-term mitigation of ammonia (NH3) and nitrous oxide (N2O) emissions by biochar soil amendments has been reported, but limited knowledge of the mechanisms, particularly those associated with long term changes, remain relatively unknown. In order to investigate potential mechanisms and residual effect of biochar on NH3 and N2O emission, a 3-year field trial was set up on an Ultisol in western Kenya with a three-replicate full factorial treatment structure. The factors investigated include…
• Publication 6 December 2022 The nexus between nationally determined contributions and technology needs assessments: a global analysis The role of technology in combatting climate change through mitigation and adaptation to its inevitable impacts has been acknowledged and highlighted by the Parties to the United Nations Framework Convention on Climate Change (UNFCCC). In the developing world, this has received particular attention through the technology needs assessment (TNA) process. As Parties put forward their national pledges to combat climate change, the scarcity of resources makes it important to assess (i) whether…
• Publication 5 December 2022 Implications of the international reduction pledges on long-term energy system changes and costs in China and India This paper analyses the impact of postponing global mitigation action on abatement costs and energy systems changes in China and India. It compares energy-system changes and mitigation costs from a global and two national energy-system models under two global emission pathways with medium likelihood of meeting the 2 1C target: a least-cost pathway and a pathway that postpones ambitious mitigation action, starting from the Copenhagen Accord pledges. Both pathways have similar 2010–2050cumulative…
• Podcast 2 December 2022 Energy Efficiency: From the Boiler Room to the Board Room Problem: Energy efficiency can enable more than 40% of the required GHG reductions to achieve global climate goals without requiring new technology breakthroughs. Improved energy efficiency has the potential to create new jobs, foster innovation, improve the productive use of electricity -i.e., cooling, clean cooking, lighting, heating, mobility, etc.- and boost economic growth. Energy efficiency is the fastest and most cost-effective way to reduce fossil fuel demand and build a cleaner and…
