The document is a letter from a coalition of Canadian organizations supporting the Pan-Canadian Framework on Climate Change and Clean Growth. The authors argue that Canada's long-term prosperity depends on investing in a low-carbon economic transformation to remain competitive in a global clean technology market. They emphasize the necessity of 'just transition measures' to support workers and communities affected by the shift away from high-carbon sectors. The coalition offers specific support for implementing the framework, including prioritizing engagement with Indigenous communities based on the United Nations Declaration on the Rights of Indigenous Peoples, establishing a robust federal backstop for carbon pricing, and modernizing electricity and transportation systems to reduce greenhouse gas emissions.

The report finds that the COVID-19 lockdown led to a significant reduction in air pollution in Bengaluru, primarily due to a sharp decline in motorized transportation. Analysis of 26 monitoring stations showed an average 28% drop in PM2.5 levels, while satellite data indicated a 40% reduction in NO2. The most significant decrease occurred near Bellandur Lake (75%), attributed to the halt of construction and vehicular movement. Conversely, the lowest reduction was seen near Halasuru Hospital (14%), likely due to continued essential hospital visits. The study concludes that the transportation sector is the primary driver of air pollution in the city and recommends shifting to electric vehicles, enhancing public transport, and promoting non-motorized transportation to maintain breathable air quality.

The report identifies the residential sector as the largest global source of black carbon (BC), accounting for 48% of emissions in 2017, followed by transportation (24%) and industry. While emissions have declined in North America, Europe, and China due to stricter standards and fuel switching, these gains are being offset by increases in South Asia and sub-Saharan Africa, where reliance on unclean cooking fuels remains high. The document highlights critical hotspots, including eastern China and the Indo-Gangetic Plain, and notes that global BC reductions are not currently on track to meet the Paris Climate Agreement's 1.5°C warming limit.

Black carbon (BC), or soot, is a potent short-lived climate pollutant resulting from incomplete combustion of fossil fuels and biomass. It causes significant respiratory and cardiovascular diseases, contributing to millions of excess deaths annually, particularly in low- and middle-income countries. Economically, BC exposure and reliance on unclean cooking fuels cause trillions of dollars in losses. Climatically, BC warms the atmosphere by absorbing solar energy and accelerates ice melt in the Arctic and Himalayas by reducing albedo. The report argues that reducing BC emissions—especially through clean cooking fuels in sub-Saharan Africa and transportation improvements in urban areas—would prevent millions of premature deaths, reduce deforestation, and help limit global warming to 1.5°C.

The document provides a technical breakdown of CO2 emissions standards measured in grams per ton-mile and grams per brake horsepower-hour for various vehicle classes and engine types between 2014 and 2027. It covers combination tractors (day and sleeper cabs), vocational vehicles, and trailers, categorized by weight classes (Class 2b through 8) and roof heights. The data shows a general trend of decreasing allowable CO2 emissions across all categories over the specified timeframe.

The report argues that inequality and sustainability are deeply interlinked, with the wealthiest individuals contributing most to environmental degradation while the poorest bear the brunt of its impacts. Through case studies in the UK, India, and Kenya, and analysis of the energy, transport, waste, and food sectors, it identifies recurring patterns of 'double injustice' where marginalised groups are most vulnerable to climate change and pollution. The document highlights 'win-win' examples—such as distributed solar power in Bangladesh, Bus Rapid Transit in Bogotá, and insect farming in Thailand—to show that sustainable development can be designed to reduce inequality.

Peru is utilizing the SNAP toolkit to address outdoor air pollution, which causes approximately 9,373 premature deaths annually. The country has established a dedicated SLCP Unit within the Ministry of Environment and is forming inter-ministerial and technical committees to develop a national emission inventory and cost-benefit analyses for mitigation. Current priority actions target diesel vehicles, cookstoves, brick production, and solid waste, with a transition toward EURO V vehicle emission standards between 2010 and 2021. Notable achievements include the installation of 235,263 certified clean cookstoves by June 2012 and the adoption of 145 new technologies in artisanal brick production since 2012.

The document outlines the methodology for the Klimatkalkylatorn tool, which estimates a user's climate footprint across four consumption categories: housing, food, transport, and shopping, plus a fixed societal impact. It details the use of Swedish national statistics (SCB), the GTAP input-output model for indirect emissions, and specific emission factors for energy and transport. The tool compares individual results against a Swedish average of 10.7 tonnes CO2e, a global average of 6.4 tonnes CO2e, and a 2020 target of 7 tonnes CO2e per person.

The document highlights a growing gap between Scotland's territorial emissions, which decreased by 13% between 1995 and 2004, and its consumer emissions, which grew by 11% in the same period. This trend indicates an increasing reliance on imported products and the offshoring of production emissions. Household consumption is the primary driver of the carbon footprint, with housing, transport, and food and drink as the largest contributors. The brief emphasizes that high-income households have significantly larger footprints and recommends that the Scottish government integrate consumer-based accounting into its national framework to ensure real emission reductions.

Côte d’Ivoire is utilizing the SNAP initiative to identify and mitigate short-lived climate pollutants (SLCPs) to improve public health, agriculture, and climate. Priority areas for action include the transportation sector, waste management, industrial processes, oil refineries, and the use of traditional cookstoves. The country is employing the LEAP-IBC tool for emission inventories and planning, with the goal of informing its air quality strategy and the implementation of the Paris Agreement.
