Tellus Publications (Selected)
The state of California has been a historical leader on energy and environmental policy, and it is well-positioned to take a leadership role on climate. From August to November 2004, Tellus Institute worked closely with staff members of the California Energy Commission (CEC), the Air Resources Board (ARB), the California Environmental Protection Agency, and other state agencies to review existing forecasts, identify strategies, and compile estimates of potential emissions reductions that are likely to be compatible with strong, long-term economic growth. This report presents the methods, assumptions, and findings of this assessment and served as a basis for Governor Schwarzenegger's climate target announcement on June 1, 2005.
Turning the Corner on Global Warming Emissions: An Analysis of Ten Strategies for California, Oregon, and Washington
This report makes a compelling case that the West Coast states can significantly reduce their global warming emissions over the next fifteen years. By 2020, the ten strategies in this report would reduce global warming pollution by 200 million metric tons—26 percent below the emissions that would otherwise occur, and 1 percent below today’s levels. While these reductions are not nearly enough to stabilize the climate, the ten strategies would represent a significant down payment on deeper emissions reductions.
To achieve necessary emissions reduction goals, emissions from the power sector, currently responsible for 40 percent of annual US CO2 emissions, must be dramatically reduced. Fortunately, there are technologies available today affecting both electricity consumption and production that could bring about this change. This report examines the policies and measures needed to accelerate the use of those technologies and dramatically reduce US heat-trapping gas emissions by 2020. It explores a broad set of national policies to increase energy efficiency, accelerate the adoption of renewable energy technologies, and shift energy use to more efficient power systems while reducing the electricity bills of consumers and businesses.
This study considers modifications to the Clean Air Act that would increase the number of emission allowances allocated to renewable energy generation to enable renewables to compete fairly in emission trading and clean air compliance markets, and estimates the economic and environmental benefits of these changes. This analysis provides better understanding of the benefits that would derive from a renewables role in Clean Air Act compliance regimes. The estimated impacts of these modifications are compared with those of other policies, including national renewable portfolio standards (RPS), a tighter cap for sulfur dioxide (SO2) emissions and trading, modifications to the State Implementation Plans (SIP) for (nitrogen oxides (NOx) trading), multi-pollutant cap/trade, and a combination of multi-pollutant cap/trade and RPS.
Characterization of Criteria Air Pollutant and Greenhouse Gas Emission Factors Associated with Energy Use in the USA: Sources, Assumptions, Methodology
This report characterizes emission factors for both criteria air pollutants and greenhouse gas emissions for a variety of processes across the industrial, commercial, residential, transport, and electric sectors. This report is divided into two major parts, one for baseline-based emission factors and the other for measure-based emission factors. Baseline-based emission factors represent average sector-wide emission factors based on the existing and projected equipment vintage, and expected future emission regulations. Measure-based emission factors represent average lifetime emission factors for new technology. The sources, assumptions, and methodology used in characterizing these emission factors are included.
This paper presents the results of a study showing that the United States could dramatically reduce its greenhouse gas emissions over the next two decades while the economy continues to grow. It examines a set of policies to increase energy efficiency, accelerate adoption of renewable energy, reduce air pollution, and shift to less carbon-intensive fuels. The policies are targeted within and across sectors—residential and commercial buildings, industrial facilities, transportation, and power generation. They include incentives, standards, codes, market mechanisms, regulatory reform, research and development, public outreach, technical assistance, and infrastructure investment.
In order to create a responsible, forward-looking energy policy, the United States will need to examine a number of important issues. Will the policy help meet America’s energy needs? Will it enhance national security? Will it contribute to a strong economy? Will it help meet America’s needs for a safe and healthy environment? In order to begin to answer these questions, World Wildlife Fund commissioned the Tellus Institute to consider the potential impacts of implementing a broad suite of clean energy policies over the next twenty years. This study analyzes the employment, macroeconomic, energy, and environmental impacts of implementing such policies.
