Abstract
Abstract A global warming potential of albedo (GWPA) is proposed, that represents the carbon dioxide emissions equivalent to a 0.01 increase in albedo over 1 m2 of horizontal surface. A survey of prior literature suggests GWPA ≈ −4.2 kgCO2/m2. Taking Los Angeles, CA as a test site for urban global warming mitigation actions, a residential “cool roof” project offers approximately seven times as much radiative forcing benefit from albedo change as from GHG reduction of energy efficiency; and a citywide increase to commercial building roof albedo offers radiative forcing benefit equivalent to the first 6½ years of all commercial sector GHG emission reductions proposed in the City of Los Angeles climate action plan. Discussion explores pathways and challenges to making albedo increases fungible with GHG reductions in GHG markets.
期刊介绍：
Carbon Management is a scholarly peer-reviewed forum for insights from the diverse array of disciplines that enhance our understanding of carbon dioxide and other GHG interactions – from biology, ecology, chemistry and engineering to law, policy, economics and sociology.
The core aim of Carbon Management is it to examine the options and mechanisms for mitigating the causes and impacts of climate change, which includes mechanisms for reducing emissions and enhancing the removal of GHGs from the atmosphere, as well as metrics used to measure performance of options and mechanisms resulting from international treaties, domestic policies, local regulations, environmental markets, technologies, industrial efforts and consumer choices.
One key aim of the journal is to catalyse intellectual debate in an inclusive and scientific manner on the practical work of policy implementation related to the long-term effort of managing our global GHG emissions and impacts. Decisions made in the near future will have profound impacts on the global climate and biosphere. Carbon Management delivers research findings in an accessible format to inform decisions in the fields of research, education, management and environmental policy.
