The document provides a comprehensive analysis of nature-based solutions (NBS) as a means to address urban climate challenges. It evaluates the efficacy of various NBS—such as urban wetlands, green roofs, and sustainable urban drainage systems (SUDS)—in regulating temperature, managing stormwater, and improving air quality. Beyond environmental benefits, the report examines the positive impacts of urban green spaces on public health and social cohesion, while critically addressing issues of environmental justice and the risk of 'green gentrification'. It also explores the governance and financial barriers to NBS implementation, proposing a 'mainstreaming' framework to integrate these solutions into municipal planning and policy.

The research paper examines how urban forests influence air quality and public health. It highlights that trees improve air quality by directly removing gaseous pollutants and particulate matter, and indirectly by reducing urban heat island effects and building energy demand. However, it notes that trees can also emit volatile organic compounds (VOCs) and pollen, and may trap pollutants near emission sources like roadways if not designed correctly. The paper concludes that while the overall effect is positive, local forest design is critical to maximize health benefits.

The document defines Ecohealth as the recognition that human well-being depends on healthy ecosystems, specifically emphasizing the role of watersheds. It argues that managing watersheds provides 'double dividends' by improving both social and environmental health determinants. The text highlights the cost-effectiveness of ecosystem restoration over engineered solutions and notes that climate change increases water-related risks in Canada. It calls for breaking down 'silos' between health and environmental practitioners and provides case studies from British Columbia and Manitoba to illustrate the benefits of integrated watershed stewardship.

The IISD Climate Change and Energy Team provides research, policy recommendations, and capacity building to help governments, corporations, and communities transition to low-carbon societies and adapt to climate change. The team focuses on the Kyoto Mechanisms, carbon markets, and the development of a post-Kyoto climate regime, while maintaining the Institute's status as a carbon-neutral organization.

The document serves as an introduction to an assessment of the 2010 NPT Review Conference's final document. It aims to determine if the outcomes represent a significant step toward the total elimination of nuclear weapons, specifically analyzing these results through an African lens.

The briefing discusses the NPT Preparatory Committee meeting held from 4 to 15 May 2009 in New York, which serves as the final session before the 2010 Review Conference. It details the NPT's three pillars—non-proliferation, disarmament, and peaceful use of nuclear energy—and emphasizes Africa's commitment to these goals through the Treaty of Pelindaba. The document highlights the leadership of Zimbabwe's Ambassador Boniface Chidyausiku as chair of the 2009 meeting and urges African states to support the total elimination of nuclear arsenals and the entry into force of the Comprehensive Nuclear-Test-Ban Treaty.

The document argues for a strong Arms Trade Treaty (ATT) to regulate the international transfer of conventional arms, which currently lacks global standards based on human rights and international humanitarian law. It highlights that the failure to regulate this trade results in significant loss of life and impacts livelihoods. Following an unsuccessful round of UN negotiations in July 2012, the brief calls for a collective responsibility to preserve human security and prevent human suffering, urging African states to prioritise specific text areas at the subsequent UN conference scheduled for March 2013.

The report advocates for a 'solve for pattern' approach to global crises, using energy efficiency and renewable technologies as a model for broader resource management. It argues that the U.S. and other nations can achieve significant reductions in oil and electricity use through technical innovations like 'hypercars' and efficient lighting, which are often cheaper than expanding supply. The authors contend that these efficiencies can simultaneously improve economic health, reduce greenhouse gas emissions, slow nuclear proliferation by removing the need for civilian nuclear power, and enhance global security by reducing dependence on foreign oil.

The text examines the crisis of freshwater depletion and proposes 'natural capitalism' through water efficiency. It details technological and behavioral shifts in agriculture (drip irrigation), landscaping (xeriscaping), and building systems (waterless toilets, graywater recovery), while advocating for decentralized biological wastewater treatment like 'Living Machines'.

The text presents 'green development' as a superior paradigm for real estate, demonstrating through case studies that integrating passive design, high-efficiency technology, and human-centric planning reduces costs and increases financial returns. It highlights the economic benefits of improved labor productivity due to better indoor environments and argues that current market incentives for architects and developers are 'perverse' because they reward inefficiency. The document details specific technical innovations in lighting, insulation, and appliances, while advocating for 'New Urbanism' to reduce infrastructure costs and restore community vitality.

A joint statement by Medact, the Chartered Institute of Environmental Health, and Scientists for Global Responsibility welcoming the 2017 Treaty on the Prohibition of Nuclear Weapons (TPNW) and the 2017 Nobel Peace Prize for ICAN. The organisations argue that nuclear weapons are indiscriminately destructive, that no meaningful medical response to a detonation is possible, and that even limited use would cause global climate damage and mass starvation. They urge the British Government to sign the TPNW and engage in multilateral discussions to eliminate nuclear weapons.

The document argues that the costs of failing to reduce carbon emissions in the United States are prohibitive, citing projected damages to coastal infrastructure, public health, water resources, agriculture, transportation, and energy systems. It highlights that under high-emissions scenarios, the annual economic impact could reach 1.9 percent of GDP by 2100. Specific regional risks include severe sea-level rise in Florida and the Northeast, extreme heat waves in Midwestern cities, water scarcity in the Southwest, and increased wildfire frequency in the West Coast and Rocky Mountain regions. The document advocates for a reduction of carbon emissions by at least 80 percent from 2005 levels by 2050 to avoid the worst consequences.

The document details the technical approach for estimating the economic and environmental impacts of fuel efficiency standards. It specifies the use of updated census data, regional energy projections, and specific emissions derivation methods for cities and states.

The report assesses fuel cell vehicles (FCVs) as a path toward a clean-vehicle future in the US, focusing on hydrogen and methanol as primary fuels. It analyzes the environmental benefits, such as the potential for 'zero-emission vehicles' (ZEVs) when using renewable hydrogen, and compares FCV performance and safety to gasoline vehicles. The document also addresses the infrastructure challenges of hydrogen distribution and the economic value of reducing urban air pollution in cities like Los Angeles and New York City.

The document details how a warming climate will increase the frequency and severity of heat waves and heavy precipitation in the Midwest, leading to higher mortality, infrastructure damage, and agricultural losses. It highlights specific risks to the Great Lakes shipping industry due to falling water levels and the threat to public health from water-borne diseases and combined sewer overflows in cities like Chicago and Milwaukee.

Since 1970, the Northeast has seen an average temperature increase of 2°F, leading to longer growing seasons and reduced snowpack. Future high-emissions scenarios project further warming, significant reductions in winter snow seasons, and increased frequency of extreme heat and flooding. These changes threaten the dairy and fruit industries, particularly cranberries, and risk substantial damage to coastal infrastructure in cities like New York and Boston. Additionally, the region's $7.6 billion winter recreation industry and specific fisheries, such as cod and lobster, face disruption due to warming waters and reduced snow cover.

The document examines public communication strategies for Low Emission Zones (LEZ) and Congestion Charging (CC) across 10 cases in Europe, Asia, and the United States. It identifies two primary consultation types—scientific/professional and consultative/political—and emphasizes that communication must be integrated into the policy design process from the feasibility stage. The paper provides a set of recommendations for implementing these schemes in China, highlighting the need for proactive public education, early stakeholder engagement, and the use of exemptions to manage opposing views.

The document argues that ecosystems are often managed for short-term gain because their non-marketed services—such as climate and water regulation—are treated as having no value. To address this, it outlines six pathways: mainstreaming ecosystem values in national economic accounts, improving local decision-making through an 'ecosystem service corps', scaling up natural infrastructure for water and coastal defense, increasing corporate investments in the food and beverage sector, using 'restoration bonds' for agricultural landscapes, and utilizing strategic communication following natural disasters to highlight community resilience.

The document argues that integrating natural infrastructure—such as forests and wetlands—with built infrastructure can reduce water treatment costs and enhance water security. It provides a framework for 'green-gray analysis' to compare these options, discusses the scientific links between forest cover and water quality, and outlines various finance mechanisms and stakeholder engagement strategies to scale these efforts across the U.S.

Wetlands are aquatic environments that provide critical ecosystem services, including carbon sequestration and water filtration, yet 87% of the world's wetlands have been lost over the last 300 years. They can store up to 50 times more carbon than rainforests and support the livelihoods of 300 to 400 million people. Conservation efforts include the Freshwater Challenge, which aims to commit 350 million hectares of degraded wetlands to restoration by 2030.
