Inflation Adjustment

Inflation-adjusted figures are converted into current dollars using the U.S. city average Consumer Price Index (CPI) of all urban consumers, published by the Bureau of Labor Statistics. For state level comparisons, inflation-adjusted figures are converted into current dollars based on state-specific deflators, published by the Bureau of Economic Analysis, U.S. Department of Commerce.

Gross Domestic Product

Nominal gross domestic product (GDP) data for California, U.S. states and the U.S. are sourced from the Bureau of Economic Analysis, U.S. Department of Commerce. Country and state GDP are at market prices in current 2018 dollars, expressed per U.S. dollar, unless otherwise noted, from the World Bank’s World Development Indicators. Gross Domestic Product by State is also referred as Gross State Product (GSP).

Population

Population data from California used to calculate per capita figures are from the California Department of Finance’s: E-4 Population Estimates for Cities, Counties and the State, with 2000, 2010, and 2020 Census Counts. U.S., state and “U.S. without California” population data are from the U.S. Census Bureau, Population Estimates Branch. Country population data are from the U.S. Department of Agriculture’s Economic Research Service, calculated from the Census Bureau International Population Database.

Carbon Economy

Global Fossil Fuel Combustion, Carbon Economy, and Emissions Per Capita in California and Other Regions

Data for carbon dioxide emissions from the consumption of energy are from the U.S. Department of Energy – Energy Information Administration (EIA), International Energy Statistics. State level emissions data come from EIA’s State CO2 Emissions. Data for carbon dioxide emissions from the consumption of energy include emissions due to the consumption of petroleum, natural gas, and coal, and also from natural gas flaring. Energy consumption data are based on the consumption of each primary energy source, and data are gathered from a variety of national and organization reports that collate data from energy users. Carbon dioxide emissions are calculated for each individual fuel by applying carbon emission coefficients to convert to MMTCO2e dioxide emitted per quadrillion BTU of fuel consumed. Calculations used GDP and Population data where applicable, as described above.

Unless otherwise noted, emissions data only include energy-related emissions that result from consumption of fuels, and therefore do not include emissions from sources such as agriculture, waste combustion, and industrial gases, because it is the most up-to-date information available. While these other emissions are important to track and reduce, the Green Innovation Index focuses on energy emissions, given the importance of energy-related indicators and the availability of recent data. A comparison of World Resources Institute’s 2011 total world emissions data shows that energy-related emissions account for about 75 percent of global emissions. In addition, the ranking for the top emitters is similar when comparing total and energy-related emissions, and the rankings of the top six emitters are identical.

GHG Emissions and Gross Domestic Product, Total California Greenhouse Emissions, Emissions by Source, Emissions by Detailed Source Greenhouse gas (GHG) emissions data for these figures are from California Air Resources Board’s “California Greenhouse Gas Inventory – by Sector and Activity” (2022 Edition). The 1990–1999 emissions include “gross emissions” and the 2000–2020 emissions are “included emissions” only unless otherwise noted. Calculations used GDP and Population data where applicable, as described above.

Note: The California Green Innovation Index seeks to report the most accurate data available on California’s carbon economy, including updated estimates of historic emissions data. Historical data in the latest edition of the Index can sometimes conflict with previous edition, if data publishers revise their own estimates and methodology. The 2022 California Air Resources Board GHG Inventory features revised methodology, which result in data change for the years 2000-2019 in the 2022 Index. While these may conflict with previously published estimates, they represent the best available estimates as of December 2022. Please see the CARB’s Technical Documentation to find out more.

Disposal Rate

Data on waste disposal (landfilled or exported) in tons are from CalRecycle’s Disposal Reporting System. The Disposal Reporting System (DRS) is the set of guidelines that tracks the origin of waste disposed in California’s landfills, and waste sent from California to out-of-state landfills. DRS tracks disposal tonnages (including alternative daily cover (ADC), alternative intermediate cover (AIC), and beneficial reuse) and transformation sent to facilities in the state. Disposal and alternative daily cover (ADC) tonnage is subject to change due to revisions.

Transportation Fuel Consumption

Data on state-level transportation fuel consumption is compiled by the Alternative Fuel Data Center of the U.S. Department of Energy, based on the State Energy Data System from the U.S. Energy Information Administration. Transportation fuel consumption is converted to gasoline gallon equivalents of petroleum (GGEs) for the transportation sector. The following transportation fuel are converted: Gasoline, diesel, propane, natural gas, and electricity.

Wildfire Emissions

Data on historic wildfire emissions (2000–2020) is provided by California Air Resources Board. Greenhouse gas emissions from wildfires are tracked separately when compared to anthropogenic sources due, in large part, to carbon cycling. Current estimates of wildfire emissions for 2020 comes from the European Centre for Medium-Range Weather Forecasts. Wildfire emissions are displayed using the 100-year global warming potential horizon.

Special Topic: Assessing the Impacts of Climate Investments in California: 2012 to Today

IMPLAN Analysis

Impact estimates in the Special Topic are based on an economic analysis technique known as input-output (I-O) analysis, which is a means of examining inter-industry relationships within an economy. An I-O analysis captures all monetary market transactions between industries in each period and within a specified region. The results of the analysis allow for examination of the effects of a change in one or several economic activities on an entire economy.

IMPLAN expands on the traditional I-O approach to include transactions between industries and institutions and between institutions themselves, thereby capturing all monetary market transactions in a given period. This specific report makes use of the IMPLAN V3 model. For more information on the IMPLAN modeling process, visit IMPLAN.com

While IMPLAN provides an excellent framework for conducting impact analysis, Beacon Economics takes extra precautions to ensure model results are valid, drawing on decades of experience to tailor the model to the unique project driving each economic impact analysis the firm conducts. Procedures and assumptions are thoroughly and systematically inspected for validity and individual project appropriateness before any analysis is performed.
