Change in the air The 2016 Paris Agreement set ambitious goals of keeping global temperature rise this century below 2°C, or even better, 1.5°C above preindustrial levels. Substantial interventions are required to meet these goals, particularly for industrialized countries. Duan et al. projected that China will need reduce its carbon emissions by more than 90% and energy consumption almost 40% do share reaching target. Negative emission technology is an essential element any plan. China's...
Many countries have implemented national climate policies to accomplish pledged Nationally Determined Contributions and contribute the temperature objectives of Paris Agreement on change. In 2023, global stocktake will assess combined effort countries. Here, based a public policy database multi-model scenario analysis, we show that implementation current leaves median emission gap 22.4 28.2 GtCO2eq by 2030 with optimal pathways implement well below 2 °C 1.5 goals. If would be fully...
Abstract. This paper describes GCAM v5.1, an open source model that represents the linkages between energy, water, land, climate, and economic systems. is a market equilibrium model, global in scope, operates from 1990 to 2100 5-year time steps. It can be used examine, for example, how changes population, income, or technology cost might alter crop production, energy demand, water withdrawals, one region's demand affect land other regions. including its assumptions, inputs, outputs. We then...
Reducing risks of severe outcomes and improving chances limiting warming to 2°C
A rapid and deep decarbonization of power supply worldwide is required to limit global warming well below 2 °C. Beyond greenhouse gas emissions, the sector also responsible for numerous other environmental impacts. Here we combine scenarios from integrated assessment models with a forward-looking life-cycle explore how alternative technology choices in pathways compare terms non-climate impacts at system level. While all yield major co-benefits, find that scale co-benefits as profiles...
Integrated assessment models are extensively used in the analysis of climate change mitigation and informing national decision makers as well contribute to international scientific assessments. This paper conducts a comprehensive review techno-economic assumptions electricity sector among fifteen different global integrated models. Particular focus is given six major economies world: Brazil, China, EU, India, Japan US. The comparison reveals that characteristics quite across models, both for...
A rapid transition away from unabated coal use is essential to fulfilling the Paris climate goals. However, many countries are actively building and operating power plants. Here we plant-level data specify alternative trajectories for technologies in an integrated assessment model. We then quantify cost-effective retirement pathways global country-level fleets limit long-term temperature change. present our results using a decision-relevant metric: operational lifetime limit. Even if no new...
Increased ambition and implementation are essential.
The Inflation Reduction Act subsidizes the deployment of clean electricity, hydrogen production, and carbon capture storage, which could enable additional actions by other federal, state, local policymakers to reduce emissions. Power plant rules finalized Environmental Protection Agency (EPA) in 2024 are one such example complementary policies. establish emissions intensity standards, not technology mandates, meaning power owners can choose from a range technologies control options provided...
Abstract Long term, global records of urban extent can help evaluate environmental impacts anthropogenic activities. Remotely sensed observations provide insights into historical dynamics, but only during the satellite era. Here, we develop a 1 km resolution dataset annual dynamics between 1870 and 2100 using an cellular automata model trained on 1992 2013. Hindcast (1870–1990) projected (2020–2100) under five Shared Socioeconomic Pathways (SSPs) were modeled. We find that growth SSP5,...
Closing the emissions gap between Nationally Determined Contributions (NDCs) and global levels needed to achieve Paris Agreement's climate goals will require a comprehensive package of policy measures. National sectoral policies can help fill gap, but success stories in one country cannot be automatically replicated other countries. They need adapted local context. Here, we develop new Bridge scenario based on nationally relevant, short-term measures informed by interactions with experts....
Abstract Integrated assessment models (IAMs) form a prime tool in informing about climate mitigation strategies. Diagnostic indicators that allow comparison across these can help describe and explain differences model projections. This increases transparency comparability. Earlier, the IAM community has developed an approach to diagnose (Kriegler (2015 Technol. Forecast. Soc. Change 90 45–61)). Here we build on this, by proposing selected set of well-defined as standard, systematically...
