The paper investigates whether removing tariffs on environmental goods can significantly reduce GHG emissions. It concludes that the 'Friends of the EGS' list of 153 goods would only have a material impact through renewable energy technologies, but that tariff removal alone is insufficient to drive significant uptake without accompanying policies like feed-in tariffs. The author suggests that for trade liberalization to be effective, lists must be based on objective environmental needs rather than commercial interests and must be supported by capacity-building measures in developing countries.

The document argues that a national energy efficiency resource standard (EERS) is the most cost-effective way to meet new energy needs in Alabama. According to the text, such a standard could save the state $3.6 billion and create over 5,000 new jobs. By 2015, Alabama could reduce electricity consumption by 9%, which would offset approximately 72% of the projected increase in demand. Data for 2020 projections, based on a 15% electricity and 10% natural gas savings target, estimate annual electricity savings of 12,440 GWh, a reduction in peak demand equivalent to 13 power plants of 300 MW, and CO2 emission savings of 9.8 million metric tons.

The document argues that CO2-EOR delivers net emission reductions on a life cycle basis, estimating that every barrel of EOR-produced oil emits 37% less CO2 than conventional oil and every tonne of CO2 utilized in EOR nets a 0.63 tonne emission reduction.

The research paper evaluates nine climate policy scenarios to determine the most effective way to address carbon leakage in the EU ETS. Using the CASE II model, it compares full auctioning against various border adjustment (BA) and output-based allocation (OB) strategies. The findings suggest that while full auctioning leads to a leakage ratio of 10%, border adjustments are the most efficient at reducing this ratio, often resulting in negative leakage (spillovers) where emissions in the rest of the world actually decrease. Output-based allocations also reduce leakage but are less efficient than border adjustments and can lead to higher carbon prices.

The document argues that current national emission pledges for 2020 are incomparable due to differing accounting methods and are collectively insufficient to maintain robust carbon market prices. It highlights that the global recession has reduced the actual effort required to meet these targets and warns that weak short-term pledges shift a disproportionate and potentially infeasible burden of emission reductions onto future generations to meet 2050 goals.

The world is off track to meet its 2030 forest goals, with global deforestation increasing by 4% in 2022. While some non-tropical regions met their targets, all tropical regions missed theirs, with Tropical Latin America and the Caribbean being the farthest off track. Primary tropical forest loss and emissions from deforestation also increased, while biodiversity continues to decline at an alarming rate. Forest restoration efforts remain fragmented and lack transparency, and forest degradation continues to pose a significant threat globally.

Agriculture accounts for 10–12% of Canada's greenhouse gas emissions. Implementing natural climate solutions, such as cover cropping and habitat conservation, could reduce emissions by 37.4 MtCO2e annually by 2030.

The document details a bottom-up methodology for sizing global energy waste using 2019 IEA World Energy Balance data and IIASA's PFUDB dataset. It estimates that of $12 trillion in gross global energy spending, approximately $4.6 trillion (40%) is spent on fuels that are wasted before becoming useful energy. The authors note that while the second law of thermodynamics prevents total elimination of waste, this $4.6 trillion figure represents a significant upper bound for efficiency opportunities.

In 2021, at least 3.43 billion people across 54 high-impact countries faced cooling access challenges. The rural poor population at high risk grew to 355 million, driven largely by the COVID-19 pandemic's impact on poverty, with India, Nigeria, and Bangladesh having the highest numbers. The urban poor population increased to 732 million, with China and India accounting for 36% of that growth. Additionally, the lower-middle income segment grew to 2.34 billion people, a group at risk of adopting inefficient cooling devices that could increase greenhouse gas emissions. Conversely, the middle-income population decreased by approximately 140 million people, primarily driven by declines in China and India.

The report highlights that approximately 3 billion people lack essential cooling, leading to millions of deaths annually from heatwaves, vaccine spoilage, and food insecurity. It identifies 9 high-risk countries—including India, China, and Nigeria—and categorizes vulnerable populations into rural poor, urban poor, and low-middle income groups. The document argues that meeting this demand sustainably is critical to achieving the Paris Agreement and the Kigali Amendment, as inefficient cooling could lead to a massive increase in energy demand and greenhouse gas emissions. Proposed solutions include passive cooling (e.g., cool roofs), district cooling, and innovative financing like PAYGO models.

The Stockholm Environment Institute conducted a two-year project to enhance 145 Wikipedia articles linked to SDGs 6 (water and sanitation), 13 (climate action), and 14 (life below water). By partnering with 39 academic experts, the project increased average quality scores for main texts by 22% and lead texts by 24%. The most significant improvements occurred in connectivity, article structure, formatting, and comprehensiveness, while readability remained difficult to improve due to the technical nature of the content and the expertise of the contributors.

The document identifies critical resource competitions in Zambia, particularly between hydropower and irrigated agriculture for water use during the dry season. It highlights a significant gap in cross-sector strategic planning and recommends integrated quantitative assessments to align conflicting sectoral targets as the country pursues its 2030 economic goals.

The review finds that while Indonesia's moratorium covers 42.5 million hectares of primary forests and peat lands, it provides additional protection to only 13.7 million hectares (13%) after accounting for existing protections. The authors argue the moratorium is unlikely to meet national emission targets in its current form because it excludes secondary forests and existing concessions, and suffers from enforcement gaps and a lack of data transparency.

WRI analysis indicates that Arkansas could reduce power sector CO2 emissions by 39 percent below 2011 levels by 2020 through a combination of infrastructure optimization and clean energy strategies. Key opportunities include increasing the utilization of natural gas plants to 75 percent, expanding combined heat and power (CHP) systems, improving coal plant efficiency, meeting energy efficiency targets, and increasing renewable energy sources to 15 percent of the state's electricity.

The paper analyzes the policy landscape for clean energy transition in India's MSME sector from 2010-2020, highlighting that while government commitment exists, adoption is hindered by awareness gaps, burdensome application processes, and a shift in SME priorities toward pandemic recovery. It finds that the integration of central and state schemes is more effective than stand-alone state programs.

WRI analysis indicates that Tennessee can reduce its CO2 emissions by 41 percent below 2011 levels by 2020 through a combination of infrastructure optimization and clean energy adoption. Key opportunities include increasing the utilization of combined cycle natural gas plants to reduce emissions by 11 percent and achieving 1 percent annual energy savings to reduce emissions by 10 percent. Other measures include expanding combined heat and power (CHP) systems, improving coal plant efficiency, and continuing the growth of renewable energy generation.

WRI analysis indicates that Colorado can reduce its power sector CO2 emissions by 29 percent below 2011 levels by 2020 using existing policies and infrastructure. This would meet or exceed moderately ambitious EPA standards, which WRI estimates would require reductions between 28 and 37 percent. Key opportunities include meeting renewable energy and energy efficiency targets, increasing the use of combined heat and power (CHP), maximizing the capacity of natural gas combined cycle (NGCC) plants, and improving coal plant efficiency.

In 2006, U.S. forests acted as a carbon sink, absorbing more carbon dioxide than they released and reducing total U.S. greenhouse gas emissions by 12.5%, or 884 million metric tons. This absorption exceeded the total emissions produced by the residential and commercial sectors combined.

The analysis evaluates the impact of H.R. 2454 (ACESA) on greenhouse gas emissions, finding that proposed pollution caps alone would reduce emissions by 15% below 2005 levels by 2020 and 73% by 2050. When complementary requirements are included, reductions increase to 28% by 2020 and 75% by 2050, with a maximum potential reduction of 81% by 2050 if additional offsets and supplemental reductions are utilized.

The analysis finds that seven global transport initiatives could reduce global energy-related emissions by 3.7 percent by 2050. The most significant reductions are linked to mode-shifting to rail or public transport, though these require high effort. While electric vehicle and fuel efficiency targets are ambitious, the paper notes gaps in addressing heavy-duty vehicles and total travel demand, suggesting that better policy linkages and wider geographical coverage are needed to improve effectiveness.
