Both 20- and 100-year time scales should always be reported Global warming potentials (GWPs) have become an essential element of climate policy and are built into legal structures that regulate greenhouse gas emissions. This is in spite of a well-known shortcoming: GWP hides trade-offs between short- and long-term policy objectives inside a single time scale of 100 or 20 years (1). The most common form, GWP100, focuses on the climate impact of a pulse emission over 100 years, diluting near-term… Expand

Exploring temporal aspects of climate-change effects due to bioenergy
Abstract The greenhouse gas emissions associated with bioenergy are often temporally dispersed and can be a mixture of long-term forcers (such as carbon dioxide) and short-term forcers (such asExpand
Methane emissions: choosing the right climate metric and time horizon.
Dynamic metrics offer insight into the timing of emissions, but may be of only marginal benefit given uncertainties in methodological assumptions, and multi-year technology assessments should use both short and long term static metrics. Expand
Climate neutral livestock production – A radiative forcing-based climate footprint approach
Abstract The goal of limiting mean global temperature rise to 1.5 °C, described in the Paris Agreement, depends upon urgent action to stabilize radiative forcing (RF). However, the contribution ofExpand
A quantitative approach to evaluating the GWP timescale through implicit discount rates
Abstract. The 100-year global warming potential (GWP) is the primary metric used to compare the climate impacts of emissions of different greenhouse gases (GHGs). The GWP relies on radiative forcingExpand
A theoretical basis for the equivalence between physical and economic climate metrics and implications for the choice of Global Warming Potential time horizon
The global warming potential (GWP) is widely used in policy analysis, national greenhouse gas (GHG) accounting, and technology life cycle assessment (LCA) to compare the impact of non-CO 2 GHGExpand
Asserting the climate benefits of the coal-to-gas shift across temporal and spatial scales
Reducing CO2 emissions through a shift from coal to natural gas power plants is a key strategy to support pathways for climate stabilization. However, methane leakage in the natural gas supply chainExpand
Assessing the impact of future greenhouse gas emissions from natural gas production.
A carbon price of at least 400 USD/tonne CO2 is effective in reducing cumulative GHGs by 30-60%, indicating that decarbonising the upstream component of the natural gas supply chain is achievable using carbon prices similar to those needed to decarbonise the energy system as a whole. Expand

There are enormous differences in climate impacts among facilities and over time, and if minimizing climate impacts are not a priority in the design and construction of new hydropower facilities, it could lead to limited or even no climate benefits. Expand
Short communication: climate impact of Australian livestock production assessed using the GWP* climate metric
ABSTRACT The livestock industries are responsible for a variety of greenhouse gas (GHG) emissions that vary in atmospheric lifetime and radiative efficiency. Assessing the overall contribution toExpand
Rapid and reliable assessment of methane impacts on climate
It is clear that the most effective way to limit global temperature rise and associated impacts is to reduce human emissions of greenhouse gases, including methane. However, quantification of theExpand


New use of global warming potentials to compare cumulative and short-lived climate pollutants
Parties to the United Nations Framework Convention on Climate Change (UNFCCC) have requested guidance on common greenhouse gas metrics in accounting for Nationally determined contributions (NDCs) toExpand
What Role for Short-Lived Climate Pollutants in Mitigation Policy?
An emerging strategy, which is referred to as hybrid climate mitigation (HCM), emphasizes reducing SLCPs in parallel with long-lived carbon dioxide (CO2) so as to achieve climate goals, as well as health and food security benefits, associated with some of the S LCPs. Expand
Limitations of single-basket trading: lessons from the Montreal Protocol for climate policy
Numerous policy options exist to reduce future greenhouse gas emissions. A single-basket approach, which controls aggregate emissions, was adopted by the Kyoto Protocol. Such an approach allowsExpand
A unifying framework for metrics for aggregating the climate effect of different emissions
Multi-gas approaches to climate change policies require a metric establishing ?equivalences? among emissions of various species. Climate scientists and economists have proposed four classes of suchExpand
Global and regional temperature-change potentials for near-term climate forcers
Abstract. We examine the climate effects of the emissions of near-term climate forcers (NTCFs) from 4 continental regions (East Asia, Europe, North America and South Asia) using results from the TaskExpand
Simultaneously Mitigating Near-Term Climate Change and Improving Human Health and Food Security
14 measures targeting methane and BC emissions that reduce projected global mean warming ~0.5°C by 2050 and increases annual crop yields by 30 to 135 million metric tons due to ozone reductions in 2030 and beyond are identified. Expand
Greater focus needed on methane leakage from natural gas infrastructure
It is found that a shift to compressed natural gas vehicles from gasoline or diesel vehicles leads to greater radiative forcing of the climate for 80 or 280 yr, respectively, before beginning to produce benefits. Expand

This Perspective considers the extent to which early action to reduce emissions of short-lived climate pollutants, such as methane and black carbon, would help to limit global warming. AlthoughExpand
