This research paper proposes a 'combined strategy' to reduce greenhouse gas (GHG) emissions by integrating international marketable permits, emissions fees, and country commitments. The author argues that while industrial countries are the primary source of emissions, a successful global regime must balance the economic stability of industrial nations with the development needs and fairness concerns of developing countries.

This guide by the Climate Bonds Initiative provides a framework for financial institutions and investors to evaluate the credibility and effectiveness of corporate transition plans aimed at achieving net-zero emissions by 2050.

This fact sheet by the Climate Policy Initiative outlines how adjusting Indonesia's fiscal policies can promote efficient land use and reduce greenhouse gas emissions in sectors such as forestry, oil and gas, mining, and agriculture. It identifies three primary opportunities for reform: adjusting revenue collection instruments to favor land-size-based taxes over profit-based taxes, reforming revenue transfers to local governments to discourage land expansion, and utilizing earmarking for sustainable land management programs.

This fact sheet by the Climate Policy Initiative examines how Indonesia can adjust its fiscal policies to balance the growth of its land use sector—which contributes nearly half of the national GDP—with a goal to reduce greenhouse gas emissions by 29% by 2030. The document identifies three primary areas for fiscal reform: shifting from production-based to land-size based levies, reforming revenue sharing with local governments to discourage land expansion, and earmarking Adjustment Funds for sustainable land use.

This fact sheet by the Climate Policy Initiative explores how a proposed California green bank could accelerate the decarbonization of the transportation sector, which accounts for approximately 40 percent of the state's greenhouse gas (GHG) emissions. The document identifies specific financial and risk-bearing interventions across four subsectors: passenger vehicles, alternative fuel vehicle infrastructure, goods movement, and regional planning.

This report by the Climate Policy Initiative (CPI) analyzes the palm oil supply chain in the Berau district of East Kalimantan, Indonesia. It examines the potential for increasing production through yield improvement rather than land expansion to support regional sustainability goals. The study identifies significant inefficiencies facing smallholders, including lack of land tenure and financing, while noting that large plantation companies operate more efficiently. It also highlights the absence of local refineries, which results in most crude palm oil (CPO) being exported from the region raw.

This fact sheet by the Climate Policy Initiative (CPI) evaluates the measurement, reporting, and verification (MRV) systems used by China, Germany, Italy, and the United States to track greenhouse gas emissions and climate mitigation actions. The analysis assesses these systems against six criteria: transparency, comparability, reliability, usefulness, timeliness, and completeness.

This case study describes the Epic Homes Program, an on-bill financing initiative launched by Fort Collins Utilities in mid-2018 to support residential energy efficiency and clean energy upgrades in Fort Collins, Colorado.

This briefing from the Environmental and Energy Study Institute outlines a vision for deploying high-octane, low-carbon (HOLC) fuels in North American vehicle powertrains to meet 2025 greenhouse gas emission standards. It details infrastructure progress, fuel specifications, engine testing, and the strategic importance of increasing octane ratings to improve fuel economy and reduce emissions.

The Environmental and Energy Study Institute (EESI) submitted comments to the U.S. Environmental Protection Agency (EPA) regarding the proposed Federal Implementation Plan (FIP) and model trading rules for greenhouse gas emissions from electric utility generating units. EESI advocates for a more holistic approach that gives equal weight to biomass, combined heat and power (CHP), and demand-side energy efficiency alongside other renewables. The organization also emphasizes the need to protect environmental justice communities from pollution 'hot spots' created by trading schemes and suggests improvements to the Clean Energy Investment Program (CEIP) to better support low-income housing and energy retrofits.

A 1988 policy report by the Environmental and Energy Study Institute (EESI) calling for the U.S. President and Congress to prioritize energy policy to combat global warming, improve international economic competitiveness, and enhance energy security. The document advocates for a multi-pronged approach centered on energy efficiency, renewable energy, reforestation, and international leadership to reduce greenhouse gas emissions.

This document is written testimony provided by Daniel Bresette, Executive Director of the Environmental and Energy Study Institute (EESI), to the U.S. Senate Committee on Appropriations Subcommittee on Interior, Environment, and Related Agencies on March 20, 2020. EESI advocates for maintaining or increasing funding for federal programs focused on climate change mitigation and adaptation within the U.S. Geological Survey, the U.S. Fish and Wildlife Service, and the U.S. Environmental Protection Agency.

This fact sheet from the Environmental and Energy Study Institute outlines the technology, environmental benefits, and economic considerations of hybrid-electric buses compared to conventional diesel and compressed natural gas (CNG) buses in North America.

This document is a data table detailing the CO2 emissions standards for medium- and heavy-duty vehicles from 2014 to 2027, categorized by vehicle class, engine type, and configuration.

This document outlines the data methodology used by Ember to process National Energy and Climate Plans (NECPs) and historic energy and emissions data. It details the preference for 'with additional measures' (WAM) projections, the conversion of energy units, the mapping of UNFCCC and Eurostat categories to specific sectors, and the sources used for historic generation and greenhouse gas emissions.

This fact sheet by Energy Innovation analyzes the potential impacts of the Advanced Clean Cars II (ACC II) rule, which mandates increasing sales of new zero-emission vehicles (ZEVs) starting in 2026 to reach 100 percent by 2035. Using the Energy Policy Simulator model, the document evaluates the benefits for the 16 '177 States' that can adopt this California-led standard under the U.S. Clean Air Act.

This briefing presents preliminary results from the California Energy Policy Simulator (EPS) regarding a scenario where California reduces greenhouse gas emissions by 55 percent below 1990 levels by 2030. The analysis indicates that while such a target would require an energy and industrial transition of "unprecedented speed and scope," it is achievable without new technologies and would result in significant economic gains, job growth, and public health improvements.

This fact sheet by Energy Innovation analyzes the gap between the emissions reductions projected from the Inflation Reduction Act (IRA) and the United States' 2030 Nationally Determined Contribution (NDC) target. Using the U.S. Energy Policy Simulator (EPS), the document identifies additional policy measures across electricity, industry, transportation, and buildings necessary to reach the NDC goal.

This policy brief by Energy Innovation evaluates the greenhouse gas (GHG) intensity of natural gas versus coal power plants, concluding that while natural gas can reduce emissions compared to coal over a 100-year period, it is not a sufficient solution for climate change and can be counterproductive if methane leaks are high or if it displaces renewable energy.

This fact sheet from Energy Innovation analyzes the impact of the Inflation Reduction Act (IRA) on transportation electrification in the United States. It argues that while IRA incentives for electric vehicles (EVs), charging infrastructure, and domestic supply chains are a positive first step, they are insufficient on their own to align transportation emissions reductions with a 1.5 degree Celsius climate scenario. The document details specific tax credits for passenger and commercial EVs and calls for complementary state and federal actions, such as more stringent tailpipe standards and grid investments, to accelerate the transition.
