This page provides access to data used or produced in my research. Please ask me for any data that is not on this website.
This data is described in:
Stern D. I. (2012) Modeling international trends in energy efficiency, Energy Economics 34, 2200-2208.
The paper presents graphs of the time series of the distances for some countries. Data for all countries is in the file linked below. The methods are explained in the paper. A distance of one (or log of zero) implies that a country is just on the frontier as estimated using averaged data for the entire 1971-2007 period. Countries can have time series values below zero (or a distance of less than one) because they may reach levels of energy efficiency greater than the the average best practice for the whole period. This is especially the case in the later years. The file also gives income per capita in PPP terms from the Penn World Table.
This data (pdf format) was prepared for Ma and Stern, 2006 but not published. It is briefly discussed on my blog.

Follow the link below to download a copy of Stern and Kaufmann's estimates of anthropogenic methane emissions from 1860 to 1994. The file is in text format spaced by tabs. It is an updated version (October 1998) of Table 1 in Stern D. I. and R. K. Kaufmann (1996) Estimates of global anthropogenic methane emissions 1860-1993, Chemosphere 33, 159-176.
These data are also now available from CDIAC's Trends Online.
Sulfur and GDP per Capita Database
This data set combines the ASL data and GDP per capita from the Penn World Table for the period 1960-1990. This is the dataset used in Stern D. I. and M. S. Common (2001) [Is there an environmental Kuznets curve for sulfur? Journal of Environmental Economics and Management. 41, 162-178] and in EEP Working Paper 9804. Countries are indicated by code numbers.
This data set is described in the two papers Global Sulfur Emissions from 1850 to 2000 and Reversal in the Trend of Global Sulfur Emissions. Please cite one of these two papers if you use the data in a research paper or other publication. It provides continuous time series from 1850 to 2000, 2001, 2002 (Most OECD countries), or 2003 (China, Mexico, and USA) using a combination of published and reported estimates and my own estimates. The files are in Microsoft Excel format. The data was completely updated in November 2005 when I resubmitted my paper to Global Environmental Change. The data are available on a country by country basis organized into eight global regions:
Mid-East and North Africa
Emissions are measured in thousands of metric tonnes of sulfur (i.e. Gg). This file presents estimates aggregated for the eight regions, shipping, the northern and southern hemispheres, and the World as a whole:
This is the dataset I used in some papers on global climate change. It includes surface temperature, ocean heat content and radiative forcing time series. The latter are expressed in watts per square metre rather than the original concentrations or emissions units. The file is in Microsoft Excel format and includes an explanation of the variables. The sources are described in two working papers here and here. As I have updated the data, results using this data could differ from those in the working paper.
