Abstract

This paper conducts an in-depth model diagnostic exercise for two parameters, 1) the elasticity of substitution between the capital/labour aggregate and the energy aggregate in the Integrated Assessment Model (IAM) MERGE's production function and 2) the rate at which new technologies can be deployed within the energy system. We show that in a more complementary world the model's ability to adjust the carbon intensity of its energy sector is more important whereas in a more substitutable world the ability to expand carbon free technologies is of lesser relative importance. The uncertainty in the literature surrounding the elasticity of substitution parameter, its interaction with the mechanisms of technical change, and the associated danger of grounding forward-looking analyses in historically based parameters lend support to the importance of such a diagnostic exercise. Building on work from model intercomparison studies, we investigate whether a given model's choice of strategy is primarily a function of the choice of its parameter values or its structure. As a result, a deeper understanding of what drives model behaviour is beneficial to both modellers and the policymakers who utilise their insights and output.

An AgMIP framework for improved agricultural representation in integrated assessment models

Journal Article Ruane, Alex C. ; Rosenzweig, Cynthia ; Asseng, Senthold ; ... - Environmental Research Letters

Integrated assessment models (IAMs) hold great potential to assess how future agricultural systems will be shaped by socioeconomic development, technological innovation, and changing climate conditions. By coupling with climate and crop model emulators, IAMs have the potential to resolve important agricultural feedback loops and identify unintended consequences of socioeconomic development for agricultural systems. Here we propose a framework to develop robust representation of agricultural system responses within IAMs, linking downstream applications with model development and the coordinated evaluation of key climate responses from local to global scales. We survey the strengths and weaknesses of protocol-based assessments linked to the Agriculturalmore »« less

The role of direct air capture and negative emissions technologies in the shared socioeconomic pathways towards +1.5 °C and +2 °C futures

Journal Article Fuhrman, Jay ; Clarens, Andres ; Calvin, Katherine ; ... - Environmental Research Letters

The development of the Shared Socioeconomic Pathways (SSPs) and associated integrated assessment modeling (IAM) exercises did not include direct air capture with carbon storage (DACCS) in their scenarios. However, recent more optimistic cost estimates and commercial or pilot-scale DACCS plants have led to increased attention to this technology in both IAM literature and in real-world policy discussions. DACCS is an energy-consuming negative emissions technology that has far lower land intensity than energy-producing BECCS, and afforestation. The requirement for different forms of DACCS, as well as their potential cost and energy efficiency improvements in the future will therefore pose unique interactionsmore »« less

Harmonization of global land use change and management for the period 850–2100 (LUH2) for CMIP6

Journal Article Hurtt, George C. ; Chini, Louise ; Sahajpal, Ritvik ; ... - Geoscientific Model Development (Online)

Human land use activities have resulted in large changes to the biogeochemical and biophysical properties of the Earth's surface, with consequences for climate and other ecosystem services. In the future, land use activities are likely to expand and/or intensify further to meet growing demands for food, fiber, and energy. As part of the World Climate Research Program Coupled Model Intercomparison Project (CMIP6), the international community has developed the next generation of advanced Earth system models (ESMs) to estimate the combined effects of human activities (e.g., land use and fossil fuel emissions) on the carbon–climate system.

A New Appraisal- Lessons from the History of Efforts to Value Green and High-Performance Home Attributes in the United States

Technical Report Mills, Evan

Rigorous consideration of green and high-performance (“green/HP”) features is rarely included in the property valuation process._ To help illuminate why this is the case, this report takes stock of the history of efforts to improve practices, and identifies barriers that have emerged and opportunities for overcoming them. Particular emphasis is placed on what energy and environmental policymakers and other stakeholders outside the appraisal community can contribute to the broader effort to advance professional practices. The history has unfolded in parallel with turbulent periods in the housing market for which appraisers and their customers are deemed to share responsibility, followed bymore »« less

A Hydro-Economic Approach to Representing Water Resources Impacts in Integrated Assessment Models

Technical Report Kirshen, Paul H ; Strzepek, Kenneth, M.

Grant Number DE-FG02-98ER62665 Office of Energy Research of the U.S. Department of Energy Abstract Many Integrated Assessment Models (IAM) divide the world into a small number of highly aggregated regions. Non-OECD countries are aggregated geographically into continental and multiple-continental regions or economically by development level. Current research suggests that these large scale aggregations cannot accurately represent potential water resources-related climate change impacts. In addition, IAMs do not explicitly model the flow regulation impacts of reservoir and ground water systems, the economics of water supply, or the demand for water in economic activities. Using the International Model for Policy Analysis ofmore »« less
