The analysis finds that heat and cold extremes are warming globally in line with average temperatures, with cold extremes in Siberia and Canada warming particularly fast. Extreme daily precipitation is generally increasing at a rate of approximately 7% per degree Celsius, though regional variations exist. While trends in tropical cyclone frequency are difficult to determine, their impacts have increased due to higher precipitation and sea level rise. Drought trends remain complex and highly dependent on the specific definition used.

The Green Economy Barometer 2017 reports a dichotomy in the global sustainability transition. While electric vehicle sales grew 42% in 2016 and lithium-ion battery prices fell 75% since 2011, fossil fuels (oil, gas, and coal) continued to provide approximately 86% of the world's energy. The report notes a disconnect between high-level geopolitical commitments and 'on the ground' realities, where rural economies and smallholder farmers lack investment, and automation threatens low-skilled workers. While countries like Peru, Uganda, the UK, and India have introduced green growth strategies or targets, the report warns that nature protections are being dismantled in some regions, such as India and South Africa.

The document evaluates the performance of Canadian cities against SDG 8, focusing on GDP per capita, labour productivity, median income, unemployment, and youth unemployment. While GDP and median incomes have generally risen, the report highlights persistent gender pay gaps and regional disparities in unemployment, particularly in Prairie cities.

The report highlights the explosive growth of artisanal and small-scale mining (ASM), with an estimated 40.5 million direct workers in 2017. It examines the sector's critical role in global mineral supplies—including 20% of gold and 80% of sapphires—while detailing severe environmental and health risks, particularly from mercury use in gold mining. The document analyzes the tensions between ASM and large-scale mining (LSM), the limitations of current certification schemes, and the necessity of inclusive formalization processes that address the poverty-driven nature of the sector rather than focusing solely on entrepreneurs.

The global green bond market reached a cumulative issuance of USD 521bn by 2018, with USD 167.6bn issued in 2018 alone. The USA, China, and France emerged as the leading national markets. The report highlights a significant increase in issuance from financial institutions, particularly commercial banks, and a growing trend toward shorter-dated bonds. While Europe remains the largest overall market, the Asia-Pacific region saw the highest year-on-year growth at 35%. The market is also diversifying into other labelled instruments, including sustainability, social, and blue bonds, and expanding into emerging markets through the adoption of regional standards like the ASEAN Green Bond Standards.

The report finds that while electricity access finance in 20 high-impact countries increased to USD 30.2 billion per year in 2015-16, it remains far below the USD 52 billion needed annually for universal access by 2030. Investment is heavily skewed toward non-residential consumers and grid-connected technologies, including a doubling of fossil fuel investments to USD 8 billion. Clean cooking finance has decreased to USD 30 million per year, a fraction of the USD 4.4 billion required. Geographically, finance is concentrated in a few countries, with Sub-Saharan Africa falling further behind despite having the highest need.

The RISE 2018 report tracks sustainable energy policies across 133 countries, finding that the number of nations with advanced frameworks tripled between 2010 and 2017. While progress is evident, the global average score of 58/100 suggests the world is only halfway to advanced policy adoption, potentially jeopardizing SDG7 and Paris Agreement goals. The report highlights a strong focus on electricity over heating and transport, a decline in utility creditworthiness in access-deficit countries, and a gap between 'on paper' regulations and actual enforcement.

The Living Planet Report 2018 documents a severe global decline in biodiversity, highlighted by a 60% drop in vertebrate populations since 1970. It identifies overexploitation and agriculture, driven by runaway human consumption, as the primary threats. The report emphasizes that nature provides essential services worth approximately US$125 trillion annually and calls for an ambitious international agreement to 'bend the curve' of biodiversity loss through a roadmap of clear goals, measurable indicators, and transformative actions.

The report provides the first comprehensive inventory of central government energy subsidies in India, covering coal, oil and gas, renewable energy, and electricity transmission and distribution (T&D). It finds that while total quantified subsidies declined from USD 35.8 billion in FY2014 to USD 20.4 billion in FY2016, support for fossil fuels remained more significant than for renewables. The study highlights a shift in the primary recipient of subsidies toward electricity T&D and notes that many consumer subsidies fail to reach the poorest populations, instead benefiting those above the poverty line.

The document tracks health and well-being indicators for Canadian cities against UN SDG 3 targets. It finds significant progress in neonatal mortality, chronic disease mortality, smoking rates, and health worker density. However, it notes rising trends in heavy drinking and HIV mortality in specific cities like Regina and Saskatoon, and an overall national increase in suicide and self-inflicted injury mortality, despite declines in several major cities.

The 2017 Global Landscape of Climate Finance report finds that global climate finance peaked at $437 billion in 2015 before declining by 12% to $383 billion in 2016. The 2015 surge was primarily driven by private renewable energy investments in China, the U.S., and Japan. While solar and wind investments are largely on track for 2°C goals, other sectors like energy efficiency and adaptation remain significantly underfunded. Public finance is increasingly focused on energy efficiency, while multilateral development finance institutions (DFIs) are progressing toward their 2020 targets. The report highlights a strong preference for domestic investment, with 79% of finance remaining within the country of origin during 2015/2016.

The document examines the role of collaborative RD&D in accelerating the deployment of climate technologies, particularly in low- and middle-income countries. It analyzes various public and private financing instruments, identifies trends such as the decline of venture capital in hardware-based cleantech, and proposes two modalities for GCF support: strengthening innovation systems and providing targeted RD&D support for specific technologies.

The report documents a general decline in open domestic ivory markets across Central Africa from 2007 to 2015, with trade shifting toward underground transactions and raw ivory exports to Asia, particularly China. While most cities saw a near total disappearance of displayed ivory, Kinshasa remained a significant hub. The decline is attributed to increased law enforcement, rising raw ivory prices driven by Asian demand, and crashing elephant populations. The report also highlights severe deficiencies in government stockpile management, with an estimated 56,497 kg of ivory leaking from state custody between 1990 and 2015.

The analysis concludes that while Hurricane Harvey was an extremely rare event, global warming increased the intensity of its precipitation by approximately 15% and made such an event about three times more likely. Observational data and climate models indicate a trend of increasing extreme precipitation along the US Gulf Coast, often exceeding the standard Clausius-Clapeyron scaling. The study emphasizes that while the storm's rarity makes it difficult to attribute its existence to climate change, the increased rainfall intensity contributed significantly to the flooding in Houston, which was further exacerbated by urban development and subsidence.

The report examines the progress of decarbonisation across three global energy sectors. It highlights the rapid growth of wind and solar power, the emerging scale of electric vehicle sales, and the relative lag in the buildings sector despite available technological solutions.

The analysis finds that February 2017 was the second warmest February on record for the contiguous United States, with temperatures 3.1°C above the 1981–2010 normal. By combining historical observations with CMIP5, HadGEM3-A, and Weather@Home model ensembles, the study concludes that the probability of such a warm event has increased more than threefold due to human-induced greenhouse gas emissions. While the 2017 event had a return period of approximately 12 years in the current climate, it would have been a 1-in-160-year event around 1900. Projections suggest that by 2050, temperatures like those seen in February 2017 will be 'completely normal', occurring roughly every three years.

The paper examines the conflict between the projected growth of the global middle class and the finite capacity of Earth's natural systems. It argues that 'business growth predicated on consumption is the new elephant in the corporate boardroom,' as traditional 'take-make-waste' models risk overshooting planetary boundaries. Using cars, beef, and apparel as case studies, the authors demonstrate that incremental efficiency gains are insufficient to offset the volume of increased demand. The document recommends that companies 'do the math' on their resource dependencies, lead industry-wide conversations on consumption, and transform their core business models toward circularity and service-based value propositions to ensure long-term viability.

The report analyzes development trajectories for 14 Southern African countries, forecasting that while GDP is expected to grow, extreme poverty will persist due to rapid population growth and governance challenges. It uses scenario modeling to demonstrate that integrated policy interventions in governance, health, education, and infrastructure can significantly improve regional outcomes, with governance capacity identified as the primary catalyst for economic growth.

The document outlines eight key areas for electricity innovation in 2017, focusing heavily on the integration, valuation, and management of distributed energy resources (DERs). It highlights the shift toward technology-agnostic DER valuation, the potential for electric vehicles to serve as grid assets, and the need for alternative capital planning to displace traditional infrastructure. The text also addresses the necessity of evolving utility business models, establishing distribution system operators (DSOs), improving customer engagement, and expanding DER access to low- and moderate-income customers.

In 2016, the European power sector saw a significant shift from coal to gas generation, which drove a 4.5% decrease in CO2 emissions. While renewable energy's share of the electricity mix rose slightly to 29.6%, growth was below previous trends due to poor weather conditions, although record-low auction prices for wind and solar suggest future potential. Electricity consumption remained largely stagnant, barely offsetting economic growth. The EU Emissions Trading System (EU-ETS) continued to suffer from a structural oversupply, with the surplus exceeding 3 billion tonnes of CO2 for the first time.
