The paper examines the potential for international offsets to provide a net decrease in global GHG emissions, distinguishing between 'surplus reductions' (actual abatement exceeding credits issued) and 'net atmospheric benefit' (reductions beyond country pledges). It argues that achieving a net benefit requires high confidence in additionality, the implementation of measures like pre-issuance discounts or stringent baselines, and accounting rules that prevent double-counting. Analysis of the Clean Development Mechanism (CDM) suggests that industrial gas projects (HFC-23 and N2O) are the most promising candidates for yielding a net decrease, potentially providing 80 to 100 million tonnes CO2e in 2020, provided host countries do not count these reductions toward their own pledges.

The document advocates for a 'nexus' approach to land management to address the conflict between the need for increased agricultural productivity and the reality of land degradation. It highlights that while 24% of global land is degraded, a significant portion is improving through restoration. The proposed nexus approach seeks to move beyond the narrow goal of maximizing yields to reduce tradeoffs and build synergies between water, energy, food, and climate regulation.

The document assesses the impact of international GHG offsets on global emission-reduction pledges, warning that double-counting reductions could significantly dilute climate ambition.

The paper examines Russian interests in Barents Sea oil and gas, using the Shtokman field as a case study. It argues that turning hydrocarbon deposits into resources requires a supportive societal context, including technology, markets, and legal frameworks. The analysis highlights the tension between the Russian state's geopolitical goals and the commercial viability concerns of companies like Gazprom and foreign partners. Ultimately, the Shtokman project was postponed indefinitely due to high costs, falling European demand, and competition from North American shale gas.

The analysis finds that sustainable development benefits vary significantly across bioenergy project types, with those utilizing agricultural farm residues claiming the most benefits and those using industrial forest residues claiming the fewest.

The document provides a framework for city governments to prioritize greenhouse gas (GHG) reduction actions. It develops a typology of urban-scale technologies and practices, identifies supporting policies, and evaluates their abatement potential for 2020 and 2050, with a particular focus on the transport and buildings sectors.

The research evaluates the impact of a tiered pricing drought plan implemented by the El Dorado Irrigation District (EID) using a discrete continuous choice (DCC) model within a water evaluation and planning (WEAP) framework. The analysis finds that the drought plan significantly reduces consumer welfare loss compared to a scenario with no plan, as current consumption levels exceed essential needs. The study also examines non-monetary performance metrics, including reservoir storage and hydropower generation, concluding that the EID bears most of the plan's costs through reduced revenues.

The authors argue that the lack of integration in resource assessments and policy-making results in inconsistent strategies and inefficient resource use. To remedy this, they introduce the CLEWs (climate, land-use, energy and water strategies) framework, which integrates the assessment of climate, land use, energy, and water strategies, noting that these resources both contribute to and are vulnerable to climate change.

The study examines the use of the traditional mbaula charcoal stove in Lusaka, Zambia, finding that while users are emotionally attached to the stove, they face significant financial burdens and health issues due to its inefficiency and fumes. The research highlights that cost is the primary driver of energy choices, and that poor households pay more for fuel due to cash-flow constraints. It proposes three main pathways for transformation: introducing locally-made, more efficient charcoal stoves that resemble the mbaula, promoting low-tech solar water heating, and restructuring electricity tariffs to make electric cooking affordable for the poor.

The document applies an eight-step process to analyze climate risks in Bagamoyo, Tanzania, by comparing local community perceptions of floods, droughts, and sea-level rise with historical data from the Dar es Salaam International Airport station and future projections under the RCP8.5 scenario. While historical data only partially confirm local perceptions of specific flood and drought events, future projections strongly suggest increasing maximum temperatures and a likely decrease in the length of the long rainy season. The study concludes that these trends threaten agriculture and health, necessitating 'climate-smart' agricultural practices and improved coastal infrastructure.

The authors analyzed sample offset projects across five programs—the Clean Development Mechanism, Climate Action Reserve, Chicago Climate Exchange, Regional Greenhouse Gas Initiative, and the U.S. EPA’s former Climate Leaders programme—focusing on landfill methane, manure management, and afforestation/reforestation. They found that variations in accounting boundaries, baseline methods, measurement rules, emission factors, and discounts result in significant differences in credited offsets, sometimes exceeding 50%. The paper argues for the harmonization of these protocols to improve offset quality and facilitate the linking of trading systems.

The paper presents a hydro-economic model linking farm-based economics with hydrologic simulation to evaluate sustainable irrigation in Spain's Middle Guadiana basin. It finds that current excessive water use threatens the European Water Framework Directive's goal of 'good ecological status' by 2015, particularly during summer low-flow periods. While the Guadiana River Basin Management Plan may improve water productivity, it may not fully ensure required environmental flows, and securing these flows would likely reduce the viability of upstream small-scale rice farms.

The paper examines the early stages of biofuel production in Tanzania, specifically in Rufiji and Bagamoyo, highlighting significant failures in land acquisition and governance. It finds that discrepancies between national policy and local implementation led to conflicts of interest, inadequate compensation for farmers, and unfulfilled community benefit promises. The study argues that the Tanzanian government's drive for foreign investment has outpaced its capacity to protect citizen rights, creating vulnerabilities that can be exploited by resource-rich investors.

The document outlines an eight-step process for integrating scientific climate data into adaptation planning, emphasizing that adaptation is a socio-institutional learning process rather than a purely technical exercise. It demonstrates this workflow through a case study in the Philippi suburb of Cape Town, where climate data is used to evaluate the trade-offs between maintaining vegetable production and rezoning land for low-cost housing. The guide highlights the importance of using both historical observations and future projections (RCP 4.5 and 8.5) to inform decisions on flood risk and heat stress.

The report develops a methodology to translate global planetary boundaries into national per capita and absolute targets. It finds that developed countries, including Sweden, frequently transgress these boundaries, particularly when consumption-based footprints are measured. The study also quantifies Sweden's 'legal competence deficit' regarding its national environmental objectives, noting that for climate impact, Sweden has no direct legal control over over 99% of the emissions threatening its goals. Finally, it analyzes the gap between planetary boundaries and international environmental agreements, concluding that while policy frameworks often exist, there is a significant implementation gap.

The article examines the persistence of the 'women-environment' linkage in global policy, noting that women are frequently framed as both primary victims of climate change and essential agents of change. It argues that this discourse persists because it provides a strategic entry point for feminist advocacy, relies on fixed projections of women's identities to gain political access, and is reinforced by the inertia of previous environmental project frameworks.

The document examines the PAARSS programme (1999-2007) in Mozambique, which integrated disaster risk reduction into water and sanitation services to build community resilience in flood-prone districts. It argues that ecosystem management is an undervalued but effective solution for mitigating hazards and reducing vulnerability, particularly as global environmental and climate changes increase disaster trends.

The document identifies critical transport-related issues in sub-Saharan Africa, noting that while the region has less than 3% of global motor vehicles, it accounts for over 11% of global road fatalities. It highlights rising urban air pollution due to fossil fuel use and inadequate emission standards, severe traffic congestion caused by poor infrastructure and land-use policies, and a policy bias toward automobiles that marginalizes vulnerable populations. Additionally, it notes that while Africa has the lowest historical greenhouse gas emissions, they are growing rapidly due to increased fossil-fuel use.

The document evaluates a variety of decision support methods for climate change adaptation, categorising them into traditional tools (CBA, CEA, MCA) and those specifically designed for decision-making under uncertainty (ROA, RDM, PA, Adaptive Management, AHP). It highlights that while traditional tools are well-known, they often struggle with the deep uncertainties of climate projections. The brief details the strengths and weaknesses of each method, provides a diagnostic framework for matching tools to specific adaptation challenges, and lists case study applications across various sectors and geographies, including the UK, Finland, Spain, and Italy.

The research demonstrates that a targeted social marketing approach in York, UK, involving the recruitment of six community teams for a six-month period of mentoring and advice, led to a statistically significant reduction in carbon emissions. Participants achieved an average reduction of 2.0 tonnes of CO2e per year, with the most substantial gains occurring in home energy and shopping behaviors.
