The document argues that urban biodiversity is essential for human quality of life and ecosystem services, but is often undermined by development pressure and inadequate planning. It outlines the legal obligations of Estonian municipalities under international conventions and EU directives, such as Natura 2000. The guide provides a framework for local governments to integrate biodiversity into strategic plans, manage municipal lands and green networks, and engage the community. It details a five-step process for considering nature values in planning and presents case studies from cities like Edinburgh, Oslo, and Malmö to illustrate successful implementation of biodiversity strategies, green roofs, and sustainable drainage systems.

The document outlines how scientists use climate models, atmospheric records, and carbon isotope signatures to prove that human-induced greenhouse gas emissions are the primary driver of global warming since the mid-20th century. It highlights the consensus among the scientific community and major bodies like the IPCC, while noting that attribution science can now link specific extreme weather events to climate change.

The 3rd GIBSA Partners' Meeting, held in April 2009 in Tshwane, South Africa, brought together representatives from Germany, India, Brazil, and South Africa to discuss the emerging global political and economic order. Key discussions focused on the transition of power from West to East, the role of 'smart power' in international relations, and the challenges facing African states in exerting influence globally. The meeting also analyzed the rise of 'club governance' (such as the G20 and Heiligendamm Process) as a flexible alternative to traditional multilateral institutions like the IMF and World Bank, while emphasizing that Africa remains more of a 'field of action' than a proactive actor in international relations.

The report critiques the DfT's cost-benefit analysis for Heathrow expansion, arguing that the projected ₤9 billion in 'generated user benefits' is based on speculative and biased assumptions regarding airfare, fuel costs, and passenger demand. It contends that without these theoretical benefits, the project's costs would outweigh its benefits by ₤3-5 billion. The authors highlight ethical concerns, noting that the benefits accrue primarily to wealthy travelers and aviation investors, while the environmental and social costs are borne by local low-income communities.

The report investigates the feasibility of reducing transport-related CO2 emissions in Yorkshire and Humber using the REAP model. It tests three scenarios: Business as Usual, Step Change, and Accelerated. Findings indicate that while a combination of practical measures (such as Bus Rapid Transit, teleworking, and rail improvements) can flatten emission growth, they are insufficient to meet the theoretical targets of the Stabilising Carbon Trends scenario. Aviation is identified as a major driver of emissions that remains largely outside regional policy control. The report concludes that the scale of investment required for these reductions is unprecedented and likely unaffordable under current funding mechanisms.

The report identifies a significant gap between the perceived importance of energy efficiency and the actual implementation of management structures in corporate real estate. While executives view sustainability as a priority, fewer than half of surveyed companies have formal energy policies or quantitative targets. The document argues that most barriers are perceived and can be overcome through integrated design, senior leadership, and the adoption of comprehensive energy management systems. It highlights that 'low-hanging fruit'—such as retro-commissioning and schedule adjustments—are often overlooked in favor of more expensive system replacements. Through case studies of companies like Adobe, Toyota, and ABN AMRO, the report demonstrates that integrated solutions and real-time data tracking can lead to substantial cost savings and carbon reductions. It concludes with action plans for corporate stakeholders and service providers, urging the adoption of the 2030 Challenge targets to achieve carbon neutrality in the building sector.

The Clean Air Task Force (CATF) conducted monitoring in Austin, Boston, New York City, and Columbus to assess diesel exhaust exposure during commutes. The study found that commuters in cars, buses, and trains are exposed to diesel particle levels significantly higher than ambient outdoor air, with the highest concentrations occurring in the presence of heavy truck traffic or when trains are pulled by locomotives. The report highlights that while commuting accounts for only about 6% of a person's day, it may contribute over half of their daily exposure to ultrafine particles. To mitigate these risks, the report recommends retrofitting existing diesel engines with diesel particulate filters (DPFs), which can reduce particle emissions by up to 90%.

The Rocky Mountain Institute (RMI) outlines immediate strategies to lower U.S. crude oil demand, arguing that a 5% to 9% reduction would remove 1.0 to 1.8 million barrels per day from the global market. Proposed measures include reducing speed limits for non-Class 8 vehicles to 60 MPH, increasing the federal Gross Vehicle Weight Rating (GVWR) for trucks to 110,000 lbs, and mandating Auxiliary Power Units (APUs) for new Class 8 tractors. RMI suggests these actions, combined with increased biofuel procurement and the adoption of 'total-flex' vehicle technology, would restore global excess capacity to 2.5 to 3.8 million barrels per day, thereby reducing price volatility.

A group of medical professionals and scientists argue that Reed Elsevier's ownership of The Lancet is contradictory to its role as a promoter of arms fairs, specifically the Defence Systems and Equipment International (DSEi) event. The authors contend that promoting arms sales, including cluster bombs and small arms, violates the medical principle of 'do no harm' and contradicts Reed Elsevier's commitment to the UN Global Compact.

The document consists of several appendices. Appendix A lists Class I areas not evaluated by the EPA. Appendix B compares SO2 and NOx reductions under CAIR versus the Best Available Retrofit Technology (BART) standard. Appendix C is a detailed scientific critique of the ARIES study, arguing that utility industry claims using ARIES to downplay the health risks of sulfates are not supported by the study's actual data or broader medical literature. Appendix D lists counties remaining in nonattainment for PM2.5 and ozone. Appendix E contains a statement from the Institute of Clean Air Companies on the achievability of NOx and SO2 limits. Appendices F through L provide detailed modeling data, cost summaries, and emission projections for various policy scenarios (CATF11, 18, 19, 21, 22, 23).

The document details an interview with Al-Sadig al-Mahdi, who argues that the bilateral peace talks between the Sudanese government and the SPLM/A are insufficient. He advocates for an 'IGAD Plus' approach that incorporates 'new forces'—including marginalized minorities and armed resistance in Darfur—and a transition to a religiously neutral, democratic constitution. Al-Mahdi proposes a strategic alliance between the Umma Party and the SPLM/A to ensure a united, democratic Sudan, while criticizing the National Islamic Front (NIF) and the historical role of the US in supporting regional dictatorships.

The document argues that reducing environmental impact requires a shift from selling products to providing services, alongside a massive transition to renewable energy and energy-efficient technologies. It outlines 'eco-design' principles and specific energy options—such as combined heat and power, hybrid engines, and various renewables—while encouraging science and engineering graduates to seek employers committed to reducing life-cycle impacts.

The MMSD North America project, implemented by the International Institute for Sustainable Development and the University of Nevada, developed a framework to transition the mining and minerals industry toward sustainability. The project produced several reports, including a set of 10 recommendations covering legacy issues, practical conditions, and long-term capacity building. It also introduced a 'Seven Questions' framework to assess the overall contribution of mining activities to long-term sustainable development.

The document details the severe impacts of sulfur emissions from coal-fired power plants in the US Midwest, specifically Indiana, Illinois, Ohio, Michigan, Minnesota, and Wisconsin. It links these emissions to premature deaths, respiratory and cardiovascular diseases, and environmental degradation including acid rain and haze. The report advocates for the adoption of sulfur-scrubbing technologies and tighter EPA air quality standards to mitigate these risks.

The report examines the multifaceted impacts of a nuclear attack on a major city, specifically London, covering radiation, infrastructure collapse, and environmental damage, ultimately questioning the effectiveness of civil defence.

The document outlines the public health benefits of shifting from car-dependency to active transportation (walking and cycling) and public transit. It links these modes of travel to reductions in cardiovascular risk, improved mental health, and lower rates of traffic fatalities. Environmentally, it highlights the role of transit and active travel in reducing traffic-related air pollution and greenhouse gas emissions to meet climate goals. Finally, it discusses how transit-supportive infrastructure reduces the financial burden of transportation for low-income individuals and improves access to essential health services.

The report recommends that the EPA strengthen PM2.5 standards to an annual limit of 11 µg/m3 and a daily limit of 25 µg/m3. According to the analysis, this standard would prevent up to 35,700 premature deaths annually and generate $281 billion in yearly economic benefits. The document highlights that current standards are insufficient and that vulnerable populations, including children and low-income individuals, are at higher risk from soot pollution.

The document details the India-UK Energy for Growth Partnership, focusing on four main areas of cooperation: capacity building for legislators, off-grid renewable ventures, the development of the offshore wind market, and the scaling of solar initiatives. It highlights the UK's role in providing technical advisory, financial modeling, and policy frameworks to help India reach its target of 175GW of renewable energy by 2022. Key efforts include the creation of the 'Renewable Energy Local Area Development toolkit' for legislators and the formulation of the National Offshore Wind Energy Policy in 2016.

The 2005 WHO Global update on air quality guidelines provides health-based recommendations for particulate matter (PM), ozone (O3), nitrogen dioxide (NO2), and sulfur dioxide (SO2). Key revisions include lowering the ozone guideline to 100 ug/m3 (8-hour mean) and the sulfur dioxide 24-hour guideline to 20 ug/m3. The guidelines for NO2 remained unchanged. The document emphasizes that no safe threshold exists for many pollutants, meaning guidelines aim to reduce risk rather than eliminate it entirely. It also introduces interim targets to help highly polluted areas progressively reduce concentrations.
