Monthly direct and indirect greenhouse gases emissions from household consumption in the major Japanese cities

Urban household consumption contributes substantially to global greenhouse gases (GHGs) emissions. Urban household emissions encompass both direct and indirect emissions, with the former associated with the direct use of fossil fuels and the latter with the emissions embodied in the consumed goods and services. However, there is a lack of consistent and comprehensive datasets outlining in great detail emissions from urban household consumption. To bridge this data gap, we construct an emission inventory of urban household emissions for 52 major cities in Japan that covers around 500 emission categories. The dataset spans from January 2011 to December 2015 and contains 12,384 data records for direct emissions and 1,543,128 records for indirect emissions. Direct emission intensity is provided in g-CO2/JPY to facilitate both future studies of household emission in Japan, as well as act as a reference for the development of detailed household emission inventories in other countries.

Analysis of Circular Economy From a Household Perspective in the USA

In this chapter, the authors conduct original research on household emissions based on data from various sources in the literature. They analyze the extent of reduction of GHG emissions by adopting zero waste strategies by the households voluntarily, incurring no costs, but rather savings in wasteful expenditure. They then model this extent of reductions using a global computable general equilibrium (CGE) model to understand what could have been the carbon tax imposed to achieve this extent of GHG reduction. From the analysis, they find about 50% of GHG potential can be reduced from household emissions, as well as the associated life cycle emissions of products consumed. Reduced wasteful expenditure may facilitate both savings-led investments and the purchase of more green products by consumers, thereby boosting the economy. Therefore, they conclude that policies that incentivize zero waste lifestyle may go a long way in reducing the supposed tradeoff between the economy and the environment. They also review some strategies for the households, based on the literature, to minimize waste.

Unveiling Key Drivers of Indirect Carbon Emissions of Chinese Older Households

The rapid urbanization and growing population aging have become salient features in China. Understanding their impacts on household emissions is crucial for designing mitigation policies for household carbon emissions. By integrating Chinese older household survey data with an unconditional quantile regression model, this paper examines the heterogeneous impacts of household characteristics on indirect carbon emissions of older Chinese households. There are three main findings: (1) The effects of urbanization on emissions at different quantiles of carbon emissions appear to be inverted U-shaped, which means that the rise of urbanization level increases carbon emissions more at the middle than at the bottom or the top, and helps to alleviate carbon emission inequality, (2) though carbon emissions rise with the increase of income, there is a clear urban-rural divide in the effects of income on carbon emissions, and (3) the rise in the share of well-educated people contributes to the increase in carbon emissions. The higher the degree of education is, the larger the impact is. These findings contribute to understanding the determinants of carbon emissions and are helpful for policymakers to design targeted policies in reducing carbon emissions from the consumption-side.

Carrots and Sticks in Private Climate Governance

When public governance fails to address important environmental threats— such as climate change—private governance by firms, not-for-profits, individuals, and households can produce significant reductions in greenhouse gas emissions. Private governance can take the form of either a carrot or a stick, using incentives or punishments. Shareholder activism as a form of private governance of corporations has largely been confrontational, leading most climate-related actions to fail. This Article examines the potential for private governance to take a more collaborative approach and to frame shareholder engagement with management in terms of opportunity. It also examines private governance successes at reducing household emissions and finds that these too emphasize making it attractive and convenient for households to act.

Affluence and emission tradeoffs: evidence from Indonesian households' carbon footprint

This study estimates Indonesian households’ carbon emissions that are attributed to their expenditures in 2005 and 2009 to analyze the pattern, distribution and drivers of their carbon footprint. Employing an input-output-emission-expenditure framework, the authors find a significant difference in household carbon emissions between different affluence levels, regions and educational levels. They also find that, while many household characteristics influence emissions, total expenditure is by far the most important determinant of household emissions, both across households and over time. Consequently, emissions inequality is very similar to expenditure inequality across households. The decomposition analysis confirms that changes in emissions are predominantly due to rising expenditures between the two periods, while expenditure elasticities analysis suggests that the rise in household emissions is mainly caused by the overall rise in total household expenditure, and not by shifting consumption shares among consumption categories. The paper discusses policy options for Indonesia to reduce this very strong expenditure–emissions link.
