The document argues that strengthening local food systems increases resilience to climate-driven supply shocks. It recommends that cities protect agricultural land through zoning and greenbelts, embrace soil-free technologies like vertical farming, and promote redundancy through municipal composting and diversified water sources. It also suggests supporting the 'cottage food industry' and community food centres to enhance local resourcefulness and food security.

The document argues that proactive investment in climate resilience reduces long-term financial risks and liability costs for municipalities. It advocates for 'multiple-bottom-line' accounting and the valuation of ecosystem services (eco-asset accounting) to prioritize cost-effective natural infrastructure over expensive engineered solutions. The briefing details various financing mechanisms to enhance urban robustness, redundancy, and resourcefulness, including green bonds, public-private partnerships, user fees, and the use of Alberta's carbon levy. It concludes with strategic recommendations to embed resilience into zoning, permitting, and planning processes.

Georgia has emerged as a leading U.S. market for electric vehicles, driven by state tax credits for vehicles and charging infrastructure. In 2014, EV drivers in Georgia saved an average of over $850 in fuel costs, contributing to a total state saving of $10 million and a reduction of over 22,000 tons of climate change emissions. The document highlights that EVs offer lower maintenance costs and lower global warming emissions than conventional vehicles, with benefits increasing as Georgia's electricity grid incorporates more renewable energy. To sustain growth, the report emphasizes the need for ongoing policy support, consumer education, and public-private partnerships.

The document argues that the Port of Seattle improperly used a SEPA categorical exemption to avoid environmental review for an interim lease of Terminal 5 to Foss Maritime. The authors contend that using the terminal as a home port for Shell's Arctic drilling fleet—including vessels like the Noble Discoverer—would change the site's use from a container terminal to a shipyard, risking toxic runoff and water pollution that could harm threatened Puget Sound Chinook salmon. The letter further highlights Shell's poor safety record in the Arctic and the broader climate implications of Arctic oil exploration.

The Stockholm Environment Institute (SEI) provides several specialized tools for climate action: LEAP for integrated energy planning and GHG mitigation; WEAP for integrated water resources planning and 'climate-proofing'; REAP and REAP Petite for consumption-based environmental impact accounting; and weADAPT, a collaborative web-based platform for sharing adaptation knowledge. SEI also leads the PROVIA Guidance project to provide technical guidance for National Adaptation Plans (NAPs). The institute's current strategy focuses on expanding capacity-building, creating 'toolkits' to address resource trade-offs, and making these technical tools more accessible to non-experts through visualization and cloud-based platforms.

Earthjustice, on behalf of Sierra Club and ForestEthics, petitions the U.S. Department of Transportation (DOT) to ban legacy DOT-111 tank cars for transporting highly flammable crude oil. The petition argues that these cars pose an "unacceptable public risk" due to high failure rates in derailments, citing disasters in Lac Mégantic, Aliceville, and Casselton. While the DOT has initiated rulemaking and issued operational emergency orders, the petitioners contend these actions are insufficient and too slow to address the imminent hazard. They highlight that Canada has already implemented bans and surcharges on these cars, which may inadvertently push the most dangerous tank cars into the U.S. fleet. The document advocates for an immediate emergency order to bridge the gap until a formal rulemaking process establishes more robust safety standards, such as the CPC-1232 specifications or newer designs.

The 2012 Seattle Community Greenhouse Gas Emissions Inventory finds that core emissions (road transportation, building energy, and waste) declined 4% from 1990 to 2012 after accounting for offsets. While absolute core emissions remained relatively flat, per person core emissions decreased by 22% over the same period, despite a 23% increase in population and a 14% increase in jobs. Road transportation remains the largest core emission source at 64%, while building energy and waste account for 33% and 3% respectively. In an expanded view including industry and air/marine travel, total emissions were 6.0 million tons CO2e in 2012, representing a 1% reduction from 1990 levels, falling short of a 7% reduction target.

The document details SEI's multi-scale approach to climate mitigation, focusing on sub-national policy for cities, the necessity of limiting fossil-fuel infrastructure to meet the 2°C target, and the strategic use of modern bioenergy in developing countries. It highlights the use of the LEAP system for low-carbon planning and describes ongoing efforts to integrate social variables into technical climate analysis.

The document details SEI's efforts to support sustainable urbanization through the development of the Water Evaluation and Planning (WEAP) tool, greenhouse gas (GHG) emission tracking frameworks, and the promotion of ecological sanitation. It highlights specific projects in cities such as Bangalore, Seattle, and Leeds, while emphasizing the importance of stakeholder engagement and the co-benefits of urban green infrastructure.

The research paper investigates a bottom-up scenario for Seattle to reach carbon neutrality by 2050, identifying potential per capita GHG reductions of 34% by 2020 and 91% by 2050 within the buildings, transportation, and waste sectors. It further proposes a "core" emissions accounting framework that excludes industrial activity and a consumption-based perspective to expand the scope of policy solutions.

The document outlines a four-step process for incorporating biodiversity into urban planning: identifying potential species, assessing data sufficiency, conducting inventories, and designing diverse habitats. It introduces the 'Green Space Factor' (PRF) and 'Green Points' (PRP) as tools to quantify and improve the ecological value of development sites. The guide provides detailed mitigation and enrichment strategies for specific animal groups—pollinators, amphibians, reptiles, bats, and birds—and describes sustainable urban infrastructure such as Sustainable urban Drainage Systems (SuDS), green roofs, vertical greenery, and flower meadows.

The research paper develops a methodology for scenario analysis of consumption-based GHG emissions, moving beyond traditional production-based accounting. It introduces a framework using a modified Kaya Identity to forecast emissions by analyzing population, consumption activity, and GHG intensity. The authors provide a catalogue of low-GHG behavioral measures across food, goods, services, construction, transport, and home energy. Piloting the method in Seattle and the U.S., the study finds that while aggressive behavioral shifts and production improvements can reduce consumption-based emissions by 47% by 2030, the resulting levels remain significantly above the global average required to limit warming to 2°C.

The RMI-BOMA guide outlines five actionable steps to improve energy efficiency in commercial buildings: increasing transparency of energy costs, engaging occupants to reduce plug loads, integrating sustainability into tenant fit-outs, planning for deep energy retrofits, and utilizing green leases to realign financial incentives between owners and tenants.

The report finds that King County's 2008 emissions were 23.4 million MTCO2e via geographic accounting and 55 million MTCO2e via consumption accounting. Transportation and buildings are the primary local sources, while consumption-based emissions are driven by imported goods and services. The report recommends a 'Core' tracking framework focusing on buildings, transportation, and waste.

District energy systems provide centralized heating and cooling to multiple buildings via underground pipes, utilizing sources such as combined heat and power (CHP) plants, waste heat, and renewables. In the United States, over 700 such systems exist, offering benefits like reduced fuel consumption, lower peak electrical demand, and decreased greenhouse gas emissions. While high upfront infrastructure costs can be a barrier, examples from universities and city centers demonstrate significant energy savings and carbon reductions.

The report outlines a pathway for Seattle to reach net zero greenhouse gas emissions by 2050. By implementing aggressive strategies across transportation, buildings, and waste, the city could reduce per capita core emissions by 91% relative to 2008 levels. Key drivers include a massive shift toward electric vehicles, deep energy efficiency retrofits in the built environment, and a transition to low-carbon energy sources like biomass-fired district energy. While the scenario achieves a 90% reduction in core emissions, the report notes that the final 10% may require offsets or sequestration.

The authors argue that current community-scale emissions targets, such as 80% reductions by 2050, do not account for the UNFCCC principle of "common but differentiated responsibility." By applying the Greenhouse Development Rights (GDR) framework to Seattle, the study finds that an equitable global obligation would require the city to become carbon "negative" before 2020. This does not imply physical sequestration but rather a role where wealthy cities dramatically reduce their own emissions while financing low-carbon transitions in developing regions. The paper suggests that communities can use offsets or direct technology and financial transfers to meet these obligations and recommends that local governments integrate global equity into their official climate action plans.

The report identifies significant barriers to deep energy efficiency retrofits in the U.S. commercial sector, primarily centered on financing, a lack of performance data, and split incentives. While 71% of surveyed stakeholders express high interest in deep retrofits, the private sector remains risk-averse, often requiring short payback periods of 2-4 years. The study concludes that providing targeted informational resources, such as case studies and improved energy modeling tools, is essential to reduce perceived risks and stimulate industry-wide activity.

The report uses data from the National-Scale Air Toxics Assessment (NATA) and the Environmental Benefits Mapping and Analysis Program (BenMAP) to quantify the health burden of diesel PM2.5. It finds that offroad diesel sources generally cause more cases of premature mortality and higher economic costs than onroad sources. The analysis employs a variety of epidemiological studies to estimate endpoints ranging from adult mortality to childhood asthma exacerbations, applying EPA-standard unit values and income adjustments to determine the economic impact.

The document details how rising temperatures in the Northwest are reducing springtime snowpack and shifting streamflow timing, which threatens water supplies, hydropower production, and salmon populations. It also highlights risks of increased forest fires, pest infestations, and coastal erosion due to sea-level rise, particularly in the Puget Sound region.
