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 paper examines the likely balance of demand and supply for carbon units in 2020, analyzing the 'emissions anyway' projections for major developed nations against their pledges. It concludes that while a theoretical demand gap exists, actual market demand for Certified Emission Reductions (CERs) from the Clean Development Mechanism (CDM) may be low due to policy preferences for sectoral crediting in the US and EU, and a likely oversupply of CERs. The author warns that this suggests a potentially low-value international carbon market, which could hinder global efforts to peak emissions by 2020.

The paper examines the complexity of comparing national emissions pledges due to inconsistent base years, varying scopes of greenhouse gases, and divergent accounting methods for LULUCF. It analyzes the specific pledges of Annex I countries (Australia, Canada, EU, Japan, Russia, Kazakhstan) and non-Annex I countries (China, India), highlighting how 'cherry picking' accounting systems can make targets appear more ambitious than they are. The authors recommend a common accounting framework where countries provide scenarios showing how energy-related emissions, LULUCF, and international offsets contribute to their total commitments.

The World Resources Institute analysis finds that while existing federal and state tools can significantly reduce greenhouse gas emissions, even the most ambitious 'Go-Getter' scenario falls short of the U.S. Copenhagen pledge to reduce emissions 17 percent below 2005 levels by 2020. The report models three levels of regulatory ambition—Lackluster, Middle-of-the-Road, and Go-Getter—across key sectors including power plants, transportation, and industry. It concludes that additional legislative action is necessary to meet international climate targets and the long-term goal of 80 to 95 percent reductions by 2050.

The document outlines a three-phase deployment of CSP in South Africa, targeting 100 GW of capacity by 2050 to save 3,850 Mt CO2-eq. It identifies critical barriers in technology, regulation, and infrastructure, specifically highlighting the need for grid expansion in the north-west and the operationalization of the Renewable Energy Feed-In Tariff (REFIT). The authors argue that international financial support is essential to overcome high investment costs and risk, proposing specific funding mechanisms for R&D and infrastructure.

The report warns that the Regional Greenhouse Gas Initiative (RGGI) risks 'undercutting itself' because it only prices emissions from power plants within its region. This creates an economic incentive for electricity suppliers in RGGI states to import cheaper, carbon-intensive power from coal-producing states like West Virginia and Ohio. The document provides 'carbon math' showing that utilizing excess capacity from 15 existing coal plants could produce pollution 'three and a half times the cuts expected under the initiative,' and that six plants under construction nearby could emit pollution equal to '140 percent of RGGI’s reductions.' To prevent this 'leak,' the authors suggest capping the entire portfolio of local electricity suppliers, limiting contracts with polluting plants, and requiring suppliers to account for emissions from electricity produced outside the region.

The report examines the Baltic Sea Region's trajectory toward 2030, contrasting a business-as-usual scenario with a sustainability vision. It argues that conventional development will lead to increased environmental pressure and persistent socio-economic disparities, whereas a sustainability vision requires decoupling economic growth from resource throughput through aggressive technological innovation and a shift in human values.

The document details how plastic production, refining, waste management, and environmental degradation contribute to global warming, projecting that cumulative emissions could consume 10-13% of the remaining carbon budget by 2050.

The report highlights that without proactive efficiency measures, the adoption of cooling appliances in households at risk could require over 240 TWh of annual electricity by 2030. It argues that implementing best-available technologies (BAT) and stringent building energy codes can offset this demand, potentially saving 18–35 TWh through improved building envelopes alone.

The document analyzes the impact of food loss and waste, noting that approximately 24 percent of calories produced for human consumption are lost or wasted. It argues that halving this rate by 2050 could significantly reduce the global food gap, saving an estimated 1,314 trillion kilocalories per year. The paper highlights that these inefficiencies lead to reduced farmer incomes, increased consumer costs, and environmental damage, including greenhouse gas emissions and inefficient land and water use.

The analysis evaluates four scenarios for reaching the $100 billion climate finance goal by 2020, concluding that a combination of diverse sources and increased public flows is likely necessary. While developed country finance alone is insufficient without extreme growth, the inclusion of Multilateral Development Bank (MDB) finance, private sector leverage, and climate-related Official Development Assistance (ODA) increases the likelihood of meeting the target even under low-growth conditions.

WRI finds that renewable energy supplies in eight major economies are projected to double by 2030, reaching 20,000 TWh, which is 18 percent higher than previous projections. Additionally, 80 percent of the 127 INDCs submitted by October 2015 referenced clean energy.
