The Clean Air Task Force (CATF) proposes that the EPA set specific emission rate standards for fossil-fueled utility boilers and natural gas combustion turbines to reduce CO2 emissions. This strategy aims to leverage existing natural-gas capacity to displace coal generation, resulting in significant carbon and pollutant reductions with minimal impact on retail electric rates.

The document examines the risks of relying on natural gas for US electricity, noting that while it burns cleaner than coal, its expected replacement of nuclear power and its role in meeting rising electricity demand would prevent necessary emission cuts. It highlights that methane leaks from production and transport further erode climate benefits, and suggests that a transition to 80% renewable energy by 2050 is a viable, more cost-effective alternative.

The study finds that taxes on local air pollutants are more regressive than those on climate change pollutants because they increase the prices of basic necessities, such as food and electricity, which occupy a larger share of low-income household budgets. While a CO2 tax was found to be nearly proportional across income deciles, the LAP tax disproportionately affected the poorest households. Revenue recycling through reduced social security contributions improved overall economic efficiency but tended to worsen the distributional equity, particularly for the GCC tax scenario.

The Clean Air Task Force (CATF) recommends that the EPA establish specific emission rate standards for existing fossil fuel-fired utility boilers (1,450 lbs/MWh) and natural gas combustion turbines (1,100 lbs/MWh). The proposal centers on a 'model' interstate emission credit trading rule that allows states flexibility in compliance, including the use of state-specific emission budgets. Analysis by The NorthBridge Group indicates this approach could reduce electric sector carbon dioxide emissions by 27 percent from 2005 levels by 2020, resulting in a total reduction of 636 million metric tons. The report argues that nearly 70 percent of these reductions would come from optimizing fossil dispatch. Beyond climate benefits, the proposal is estimated to avoid over 2,000 premature deaths annually due to reductions in sulfur dioxide and nitrogen oxides. The total monetized health and climate benefits are estimated at $34 billion in 2020, significantly outweighing the $9.4 billion compliance cost.

The analysis compares a 'No-Policy' scenario with a 'Policy Proposal' scenario for 2020, focusing on the upstream emissions from the production, processing, and transport of fuels. Under the base case using EPA figures, the policy proposal is projected to increase total upstream greenhouse gas emissions by 9.9 million metric tons (MMT) of CO2e, consisting of a 9.6 Tg increase in CO2 and a 0.3 Tg CO2e increase in methane. A sensitivity 'high case', which assumes non-hydraulic fracturing methane emissions are twice the EPA's 2011 reports, projects a total increase of 16.9 MMT CO2e. The document notes that upstream CO2 emissions are higher for natural gas (ratio of 0.108 to stack CO2) than for coal (ratio of 0.0193 to stack CO2).

The report examines the systemic failure of the U.S. coastal insurance market, specifically the National Flood Insurance Program (NFIP), which provides subsidized rates that encourage risky development and create massive taxpayer liability. It highlights how climate change—manifesting as sea level rise and stronger hurricanes—is exacerbating these risks, particularly along the East and Gulf Coasts. The author advocates for the full implementation of the Biggert-Waters Flood Insurance Reform Act of 2012 and further measures, such as incorporating sea level rise projections into FEMA flood maps and providing targeted support for low-income homeowners.

Earthjustice supports President Obama's commitment to tackling carbon pollution from power plants and clean car standards, but argues that the U.S. must prioritize 'best of the above' clean energy over an 'all-of-the-above' strategy that includes natural gas and other fossil fuels.

The report assesses Bangalore's vulnerability to climate change, water scarcity, and rising carbon emissions, highlighting that rapid, unplanned urbanisation has degraded natural resources and increased the vulnerability of the urban poor. It identifies fragmented governance and limited operational capacity as key barriers to resilience, recommending priority action in water and energy systems.

The report analyzes the current state of concentrated solar power (CSP), noting that while it has potential to supply up to 10% of global energy demand by 2050, it remains expensive and heavily dependent on public support. The authors find that over 98% of total CSP investment to date has required public support. The document outlines a plan to evaluate the effectiveness of public finance through case studies in India and South Africa, expert dialogues, and a final lessons-learned paper. It details various public support mechanisms, including feed-in-tariffs, competitive tenders, reverse auctioning, and concessional loans, while highlighting the specific challenges and opportunities in emerging markets.

The paper argues that fossil-fuel subsidies in Emerging and Developing Asia, totaling US$104 billion in 2011, represent a significant opportunity to finance the Sustainable Development Goals (SDGs). It contends that these subsidies are regressive, primarily benefiting wealthier populations while undermining investments in renewable energy and public health. Using case studies from the Philippines and Indonesia, the document demonstrates how transitioning from universal subsidies to targeted social welfare programs and fuel taxation can improve fiscal health and social equity. The author recommends that the SDGs explicitly include a goal to phase out inefficient fossil-fuel subsidies by 2030 to encourage national reforms.

The document argues that mega-FTAs like the TPP and TTIP are creating a new global regulatory regime characterized by higher standards in labor, environment, and intellectual property. For non-members like India, these agreements may create trade diversion and higher barriers to entry into global value chains (GVCs). The author emphasizes that India must upgrade its domestic policy framework and producer capacities to meet these escalating standards to avoid being isolated from international investment and markets.

The roadmap proposes two visions for Colombia's bioenergy sector: one focusing on new technologies (biomethane and biomass-based power/CHP) and another combining these with the expansion of first-generation biofuels. Modeling indicates that while both scenarios increase the bioenergy share in power and gas supply, they cannot prevent an overall decline in bioenergy's share of primary energy demand due to rapid GDP growth and urbanization. The most effective emissions reductions come from power generation and CHP, particularly by avoiding methane release from landfills and animal waste. Scenario I is identified as the most efficient in terms of emissions reduction per additional hectare of land, whereas Scenario II's ambitious biofuel targets would require significant imports as domestic land is insufficient.

The report analyzes Estonia's transport energy consumption from 2000–2012, noting a 33% increase driven primarily by road transport, which accounts for approximately 90% of the sector's energy use. It evaluates 24 measures across four categories: vehicle fuel efficiency, sustainable modes of transport, land-use planning, and fiscal measures. Key findings suggest that the highest energy-saving potential lies in shifting to more efficient conventional vehicles (A-B energy classes) and implementing smart fiscal tools like kilometer-based road charges and a Tallinn congestion charge. The report concludes that while electric vehicles have marginal impact in the short term, systemic changes in urban planning and public transport are essential for long-term demand management.

In June 2013, Mexico implemented Latin America's first fuel-efficiency standard for light vehicles, developed with support from EMBARQ Mexico and Centro Mario Molina. The standard mandates a fleet average of 14.9 kilometers per liter by 2016, aiming to reduce CO2 emissions by 170 megatons and save consumers $2,700 USD per vehicle over its lifetime. By aligning with U.S. and Canadian regulations, Mexico has harmonized its standards, potentially increasing the global competitiveness of its automotive industry.

The report examines the potential of South Africa's shale gas reserves, estimated by the US Energy Information Administration as the eighth largest globally. It contrasts a 'Base Case' of no fracking with a 'Shale Boom' and a 'Blue Bridge' scenario. While a shale boom could boost GDP and reduce poverty, it risks significant water contamination in the semi-arid Karoo region and may increase long-term carbon emissions by delaying renewable energy investment. The authors propose a 'Blue Bridge' approach, using an excise tax on fracking to fund renewable energy infrastructure, which they argue could maximize economic growth while ensuring long-term environmental sustainability.

The paper examines how Brazil, Russia, India, China, and South Africa integrate green economy principles into their national development strategies. It finds that while some countries like South Africa embrace the concept as a path to sustainable development and job creation, others, such as Brazil, view it with skepticism, fearing it may benefit developed nations or hinder economic growth. The authors conclude that for a green transition to be successful, it must be aligned with each country's specific economic priorities and social objectives.

The research argues that existing assessments of the Keystone XL pipeline overlook the 'price effect,' where increased oil supply lowers global prices and induces higher consumption. Using a supply-and-demand model, the authors find that if the pipeline enables production that would not otherwise reach the market, it could increase global GHG emissions by up to 93 million tCO2e per year by 2020. This impact is significantly higher than the emissions resulting solely from the higher carbon intensity of oil sands compared to other crudes.

A 2013 survey by the Union of Concerned Scientists and Consumer Reports found that 42% of U.S. households with vehicles could potentially use current plug-in hybrid electric vehicles (PHEVs) and 22% could use battery electric vehicles (BEVs) with a 60-mile range. The study identifies charging access as the primary barrier to EV adoption, particularly for those in multi-unit dwellings. Public sentiment is generally positive, with 65% of respondents viewing EVs as essential for reducing oil use and global warming, and 60% considering an EV purchase.

The report proposes a transition for China from fossil fuels to a system based on radical efficiency and renewable energy. It identifies three key areas for innovation: ultralighting and electrifying vehicles to eliminate oil dependence, using 'integrative design' to drastically reduce energy use in industry and buildings, and shifting toward a hybridized, distributed electric grid. The authors suggest these changes can be driven by profit and business innovation rather than just regulation.

The Clean Air Task Force (CATF) argues that the U.S. Environmental Protection Agency (EPA) should use its authority under Clean Air Act section 111(d) to mandate deep carbon dioxide reductions from existing fossil fuel-fired power plants. CATF asserts that these reductions are necessary to protect public health and meet President Obama's goal of reducing U.S. greenhouse gas emissions by 17 percent below 2005 levels by 2020. Based on analyses conducted with The NorthBridge Group, CATF claims that power sector carbon pollution could be reduced by more than 25 percent from 2005 levels by 2020 without increasing monthly bills for electric ratepayers, primarily by optimizing the dispatch of existing plants to favor efficient natural gas units over inefficient coal units.
