Considering only first-order effects? How simplifications lead to unrealistic technology optimism in climate change mitigation

  title={Considering only first-order effects? How simplifications lead to unrealistic technology optimism in climate change mitigation},
  author={Anders Arvesen and Ryan M. Bright and Edgar G. Hertwich},
  journal={Energy Policy},
This article challenges the notion that energy efficiency and ‘clean’ energy technologies can deliver sufficient degrees of climate change mitigation. By six arguments not widely recognized in the climate policy arena, we argue that unrealistic technology optimism exists in current climate change mitigation assessments, and, consequently, world energy and climate policy. The overarching theme of the arguments is that incomplete knowledge of indirect effects, and neglect of interactions between… Expand
Enabling low-carbon development in poor countries
The challenges associated with achieving sustainable development goals and stabilizing the world’s climate cannot be solved without significant efforts by developing and newly-emerging countries.Expand
Bridging the Climate Mitigation Gap with Economy‐Wide Material Productivity
Projections of UK greenhouse gas emissions estimate a shortfall in existing and planned climate policies meeting UK climate targets: the UK’s mitigation gap. Material and product demand is drivingExpand
Using Attributional Life Cycle Assessment to Estimate Climate‐Change Mitigation Benefits Misleads Policy Makers
Life cycle assessment (LCA) is generally described as a tool for environmental decision making. Results from attributional LCA (ALCA), the most commonly used LCA method, often are presented in a wayExpand
Can Rebound Effects Explain Why Sustainable Mobility Has Not Been Achieved
Since the report “Our Common Future” launched sustainable development as a primary goal for society in 1987, both scientific and political discussions about the term’s definition and how to achieveExpand
Industrial ecology in integrated assessment models
An in-depth review of five major integrated assessment models from an industrial ecology perspective reveals differences between the fields regarding the modelling of linkages in the industrialExpand
Nature-Based Solutions Forming Urban Intervention Approaches to Anthropogenic Climate Change: A Quantitative Literature Review
Discussion around anthropogenic climate change has occurred for over 100 years. However, in recent decades, these discussions have intensified due to increased confidence in scientific researchExpand
National-level energy use, rebound and economic growth : insights from useful work and exergy analysis
The global climate challenge is keeping below a 2⁰C global temperature rise (versus pre-industrial levels) to avoid runaway climate change. Urgent policy-based action is required to reduce globalExpand
The carbon payback of micro-generation: An integrated hybrid input–output approach
Feed-in Tariffs (FiTs) in the UK have been introduced to stimulate growth in small-scale renewables such as photovoltaics and micro-wind. They form one of the UK’s key policies to decarboniseExpand
Building a Bridge between Inundated Shores: Analyses on Integrated Disaster Risk Management and Climate Change Adaptation Policies and Measures
This thesis consists of an introduction and four articles which analyse disaster risk management (DRM), including disaster risk reduction (DRR), disaster management and climate change adaptationExpand
It's Complicated: Corporate Sustainability and the Uneasiness of Life Cycle Assessment
Abstract Life cycle assessment (LCA) is a technique and field of expertise aimed at modeling the complete ‘cradle-to-grave’ life of goods and services, as well as their multiple impacts onExpand


Technology Dynamics and Greenhouse Gas Emissions Mitigation: A Cost Assessment
This article analyzes long-term greenhouse gas (GHG) emissions and their mitigation in a family of high economic and energy demand growth scenarios in which technological change unfolds inExpand
Globalizing carbon lock-in
This paper extends the arguments surrounding carbon lock-in elaborated in Unruh (Energy Policy 28 (2000) 817; 30 (2002) 317) to countries currently undergoing industrialization. It argues that, forExpand
Stabilization Wedges: Solving the Climate Problem for the Next 50 Years with Current Technologies
A portfolio of technologies now exists to meet the world's energy needs over the next 50 years and limit atmospheric CO2 to a trajectory that avoids a doubling of the preindustrial concentration. Expand
Role of renewable energy in climate mitigation: a synthesis of recent scenarios
The role of renewable energy in climate change mitigation is explored through a review of 162 recent medium- to long-term scenarios from 15 large-scale, energy-economic and integrated assessmentExpand
Consumption and the Rebound Effect: An Industrial Ecology Perspective
Summary Measures taken to protect the environment often have other, unintended effects on society. One concern is that changed behavior may offset part of the environmental gain, something that hasExpand
Escaping carbon lock-in
This article explores the climate policy implications of the arguments made in “Understanding carbon lock-in” (Unruh, 2000), which posited that industrial countries have become locked-into fossilExpand
Understanding carbon lock-in
Abstract This paper narrative argues that industrial economies have been locked into fossil fuel-based energy systems through a process of technological and institutional co-evolution driven byExpand
Environmental implications of large-scale adoption of wind power: a scenario-based life cycle assessment
We investigate the potential environmental impacts of a large-scale adoption of wind power to meet up to 22% of the world?s growing electricity demand. The analysis builds on life cycle assessmentsExpand
Jevons’ Paradox revisited: The evidence for backfire from improved energy efficiency
Beginning with William Stanley Jevons in 1865, a number of authors have claimed that economically justified energy-efficiency improvements will increase rather than reduce energy consumption. 'JevonsExpand
Greenhouse-gas emission targets for limiting global warming to 2 °C
A comprehensive probabilistic analysis aimed at quantifying GHG emission budgets for the 2000–50 period that would limit warming throughout the twenty-first century to below 2 °C, based on a combination of published distributions of climate system properties and observational constraints is provided.
