The report argues that climate economics lags behind climate science, often relying on outdated damage functions and oversimplified cost-benefit frameworks. It advocates for a shift toward standards-based (precautionary) decision-making to avoid catastrophic tipping points, such as the collapse of ice sheets or the Amazon rainforest. The authors recommend that models incorporate endogenous technological change, explicit discount rate justifications, and regional equity considerations to provide policy-relevant guidance for staying below a 2°C warming threshold.

The report examines how ecosystem services—provisioning, regulating, cultural, and supporting—directly impact human well-being, particularly for poor and indigenous communities. It highlights that poverty is a multidimensional issue often tied to environmental degradation and lack of resource access. Using frameworks like the Millennium Ecosystem Assessment, the document argues for integrating ecosystem-based policies with poverty-alleviation measures to build resilience against climate change and environmental shocks. It emphasizes that without such integration, environmental protection policies can inadvertently increase poverty through maladaptation or by restricting essential livelihood access.

The document examines the current state of literature and data on subsidies for electric power generation, noting a significant lack of consistent information and a limited number of studies that attempt to quantify these subsidies across nuclear, fossil fuel, and renewable energy sources.

The document identifies a significant lack of consistent data and information regarding subsidies for both biofuels and conventional transport fuels. It argues that current global estimates are limited and emphasizes the necessity of robust national-level estimates to enable further evaluation of these subsidies.

The paper examines the instrumental link between income inequality and social trust, which is considered essential for the collective action required for sustainability. Using a generalized linear mixed model (GLMM) on World Values Survey data from 20 country-year combinations, the author finds that both absolute income and income inequality significantly influence social trust. Specifically, trust rises with income but falls as income inequality (measured by the Gini coefficient) increases. The analysis suggests that neither economic growth nor redistribution alone is sufficient to significantly raise trust levels in low-trust societies; instead, a combination of stable growth and narrowing income distributions over approximately two decades is required to produce meaningful changes in social cohesion.

The report analyzes the toxicity of 57 chemical ingredients used in oil dispersants, highlighting significant gaps in scientific research and regulatory oversight. It finds that many ingredients are linked to cancer, organ toxicity, and aquatic harm, while noting that the lack of public disclosure regarding proprietary formulas hinders a full understanding of the risks. The document criticizes the EPA's listing process for lacking safety criteria and recommends comprehensive toxicity testing and full ingredient disclosure.

The research paper examines indirect tools—capacity building and the creation of enabling environments—to remove non-financial barriers for low-carbon business activities in developing countries. It analyzes past experiences with the Clean Development Mechanism (CDM), identifies gaps in current international climate finance, and provides recommendations for the post-2012 climate regime, emphasizing the need for demand-driven, coordinated efforts and a stronger focus on the core regulatory business environment.

The report identifies three categories of information tools to support residential thermal retrofits: those that raise awareness of benefits, those that assist in planning and investment, and those that train professionals. It finds that while individual tools like detailed billing or in-home displays can reduce energy consumption by 1-10% or more, their effectiveness depends on implementation factors such as 'opt-out' participation, user education, and the quality of professional certification. The document emphasizes that information tools are generally cost-effective and can significantly catalyze energy efficiency investments when tailored to consumer needs.

The document argues that carbon markets offer indigenous communities opportunities for economic development aligned with sustainable forest management, provided that governments ensure free, prior and informed consent and protect land and carbon rights. It highlights a global lack of effort to involve indigenous peoples in carbon market policy and notes a specific information void regarding First Nations in Canada.

The paper examines the theoretical and empirical debate surrounding trade liberalisation in South Africa, specifically its effects on growth, employment, and poverty. It critiques common methodological tools, including partial equilibrium approaches, effective rates of protection (ERP), and computable general equilibrium (CGE) models, noting that they often rely on restrictive assumptions and fail to account for dynamic effects or institutional complexities. The author argues that the 'free trade' ideal is an unrealistic benchmark and suggests that South Africa should instead pursue a 'sensible management of trade' that creates dynamic comparative advantages and protects industrial policy space to achieve structural change and job creation.

The document examines technical approaches to establishing reference levels for REDD+, comparing historical baselines with forward-looking and adjusted models. It argues that while different methods exist, most produce similar emissions reductions and costs, and that prioritizing the participation of high-forest low-deforestation (HFLD) countries is essential to prevent global leakage.

The report examines how existing corruption and weak governance in forest-rich developing countries may undermine REDD objectives and how REDD resource flows could create new incentives for rent-seeking. Through case studies in the DRC, Kenya, and Tanzania, it identifies risks such as 'carbon fraud', elite capture of funds, and the marginalisation of local communities. It suggests that while REDD can act as a catalyst for improving forest governance, success depends on tailored anti-corruption measures, independent monitoring, and the integration of REDD into national development strategies.

The policy brief examines conflicts in the classification of ecosystem services (ES) for economic valuation, specifically critiquing the Millennium Ecosystem Assessment (MA) framework. By analyzing 25 valuation studies of water services in Central American tropical forests published between 1985 and 2009, the authors demonstrate that the MA framework can lead to double counting and the underestimation of service values. They propose that valuation should focus on the final outcomes (outputs) that impact human welfare rather than ecological processes. This distinction is presented as critical for accurate natural capital measurement in national accounting systems like the System of Integrated Environmental and Economic Accounting (SEEA).

The report evaluates Integrated Place-based Management (IPM) as a holistic approach to managing human-natural system trade-offs. It identifies a gap in long-term impact reporting, noting that most IPM studies focus on short-term results. The authors argue for a dual monitoring approach that combines process-based indicators (governance, participation) with outcome-oriented indicators (environmental status). Case studies in the Lake Champlain Basin, Rhine River Basin, and South Tobacco Creek demonstrate that collaborative governance and strategic planning can lead to documented improvements in water quality, such as reduced phosphorous and coliform contamination, though attributing these changes solely to IPM remains challenging due to time lags and multi-scale interactions.

The document serves as a resource for First Nations in Canada to navigate the economic opportunities and risks of carbon markets. It emphasizes that while global literature on indigenous peoples and carbon markets exists, there is a significant information void specifically regarding First Nations in Canada. The report argues that for indigenous participation to be equitable, governments must recognize carbon rights, obtain free, prior and informed consent, and adopt decentralized governance models that prioritize local employment over simple financial compensation. It also highlights the technical necessity of accurate carbon accounting, particularly in the boreal forest, where factors like insect infestations and soil moisture significantly impact carbon stock measurements.

The document assesses how Indonesia's shift from a protected to an open economy has affected its SMEs, which constitute over 90% of all firms. Despite facing significant institutional constraints—such as lack of capital, technology, and skilled labor—the author finds no evidence that trade liberalization has negatively impacted the overall number or GDP contribution of Indonesian SMEs. While most SMEs remain domestically focused or export indirectly through intermediaries, the paper argues that a free-trade regime generally provides more long-term benefits than protectionism, provided that supporting policies for human resource and technological upgrading are implemented.

The paper analyzes adaptive capacity in the Nordic countries and Russia, noting that determinants in these industrialised states differ systematically from those in mixed subsistence-cash based communities, such as those in Arctic Canada. It identifies internal disparities in adaptive capacity based on location (peripheral versus central) and national context (Nordic versus Russian), specifically regarding economic resources, diversification, infrastructure, and technology access.

The document provides a comprehensive survey of quantitative research on the health impacts of climate change, categorizing studies by their methodological approach (primary, secondary, and comparative risk assessments) and the statistical models employed (time-series, non-parametric, and panel/spatial models). It highlights the complex relationship between climatic variables and diseases, particularly malaria, and reviews major global reports from the WHO and the Stern Review to outline the broader economic and public health implications of global warming.

The report evaluates the data sources used to track fossil-fuel producer subsidies in four pilot countries—China, Germany, Indonesia, and the United States—assessing the strengths and limitations of commonly referenced databases and international data collection methods.

The paper examines the conceptual conflicts in classifying ecosystem services for economic valuation, specifically comparing the Millennium Ecosystem Assessment (MEA) framework with an output-based approach. Through an analysis of 25 valuation studies of tropical forest water services in Central and South America, the authors find that the MEA framework can lead to double counting and underestimation of values. They argue that valuation should focus on final outputs (benefits to humans) rather than ecological processes to ensure accuracy.
