The report argues that expanding I-270 will not solve long-term congestion due to induced demand and will further burden marginalized communities. It proposes a shift toward a 'Garden City' model featuring green buffers, freight-prioritized corridors with smart technology, expanded transit, and robust anti-displacement strategies. The authors criticize CDOT's current public engagement as insufficient and recommend a more deliberative, data-driven approach to rebuild community trust.

The guide explains how climate change intensifies wildfires by increasing evaporation and drying out vegetation, creating a feedback loop where fires destroy carbon sinks and emit more carbon. It highlights specific regional impacts in the United States and Canada and provides journalistic advice on covering the long-term effects of fires, such as landslides and public health crises.

The document argues that current US federal standards for landfill methane are insufficient and proposes a two-pronged approach: enhancing the monitoring and capture of methane from waste already in place and reducing the disposal of organic materials. It highlights that landfill methane emissions may be underestimated by a factor of two and that 54% of reporting landfills have adjacent communities exceeding national averages for low-income or people of color populations. Proposed solutions include the use of satellites, drones, and continuous sensors for leak detection, the adoption of biocovers, and the diversion of food waste to composting or anaerobic digestion. The authors call on the EPA to implement more ambitious federal standards under the Clean Air Act during its 2024 review.

This guide outlines a five-step process for US homeowners to transition to all-electric, energy-efficient homes. It emphasizes the importance of setting personal goals, conducting energy assessments, hiring reputable contractors, and utilizing financial incentives provided by the Inflation Reduction Act (IRA). The recommended technical path includes improving insulation and sealing, installing electric heat pumps for heating, cooling, and hot water, and switching to induction stoves.

The guide outlines five strategies for cities to leverage utility franchise agreement renegotiations: incorporating climate strategies, planning for equity, investing in resilient infrastructure, embracing collaboration, and understanding negotiation leverage. It highlights specific examples, such as San Diego's climate equity fund and Colorado's powerline undergrounding, to demonstrate how cities can align utility operations with community-wide clean energy goals.

The Union of Concerned Scientists documents how the fossil fuel industry in Colorado employs four primary disinformation tactics—The Fix, The Diversion, The Screen, and The Fake—to maintain political control and undermine public health and safety. The report details the industry's use of front groups, lobbying, and misleading economic claims to thwart regulations and ballot initiatives, while highlighting the disproportionate impact of pollution on communities of color and low-income residents. It concludes with recommendations for state regulators to prioritize science and community voices over industry profits.

The briefing outlines six funding models—sales taxes, retail taxes, fossil fuel production taxes, electricity consumption taxes, climate bonds, and resilience bonds—that US cities have implemented to fund climate action. It highlights specific examples from cities like Denver, Portland, and Miami, emphasizing that integrating equity into the design of these funding streams is essential for success, particularly for Black, Indigenous, Latino, and low-income communities who are disproportionately affected by pollution and climate change.

The document highlights how Colorado developers are adopting all-electric designs for affordable housing to reduce climate impact and operational costs. Through projects like Oxford Vista, Kestrel, and 30 Pearl Street, it shows that avoiding gas infrastructure can offset upfront costs and provide long-term savings in utilities and maintenance. These developments also improve indoor air quality and equity for low-income tenants while aligning with Colorado's state-level greenhouse gas reduction goals and city-level net-zero plans.

The author contends that the United States faces a critical housing shortage that exacerbates economic inequality, public health risks, and climate change. By removing exclusionary zoning regulations and promoting infill, multi-family, and mixed-use development, the U.S. can reduce transportation emissions—the country's largest carbon source—and create a more equitable urban environment. The text calls for the federal government to incentivize local zoning reform through programs like the Community Development Block Grant (CDBG) to enable '15-minute neighborhoods' and low-carbon construction.

The guide outlines three primary passive strategies for maintaining cool indoor temperatures: preventing heat gain through shading and reflective materials, utilizing natural ventilation like 'night flushes', and improving interior comfort with air movement and thermal mass. For active cooling, it recommends high-efficiency options such as ductless heat pumps and heat recovery ventilators (HRVs). The document illustrates these principles through two case studies in Colorado, demonstrating how super insulation, solar PV, and passive design can maintain comfortable indoor temperatures without traditional air conditioning during extreme heat.

A survey of 5,131 U.S. adults found that a majority of Americans believe fossil fuel companies are responsible for global warming damages and should bear the costs of these damages rather than taxpayers. Specifically, 57% of respondents attribute a moderate to great deal of responsibility to these companies, and 50% support local officials filing liability lawsuits against them. The data indicates widespread distrust of fossil fuel companies, with 66% of participants expressing distrust.

The Food Waste Warriors project analyzed plate waste in 46 US schools, finding that students waste an average of 39.2 pounds of food and 28.7 cartons of milk per year. The study highlights the significant environmental and financial costs of this waste, estimating a national impact of 530,000 tons of food waste and 45 million gallons of milk waste annually. Results indicate that simple interventions and awareness can reduce waste, with elementary schools seeing a 14.5% reduction. The report recommends policy reforms to National School Lunch Program (NSLP) portion sizes and the adoption of bulk milk dispensers to mitigate these losses.

The report argues that targeting rental properties for energy efficiency is a high-impact strategy for cities to meet climate goals, as rentals often suffer from a 'split incentive' where owners do not pay utility bills. Using Boulder's 'SmartRegs' program as a model, the document outlines a seven-step roadmap for other cities: determining fit, analyzing impact, consulting stakeholders, developing financing, implementing measurement tools, establishing compliance, and creating disclosure frameworks. RMI's analysis of five US cities suggests that MESR policies could significantly reduce carbon emissions at a relatively low cost to municipal governments.

This fact sheet by the Rocky Mountain Institute (RMI) challenges four primary myths regarding net-zero energy (NZE) leased buildings, asserting that they can be more profitable for developers and more beneficial for employees than traditional buildings. Using the Boulder Commons project as a case study, RMI demonstrates that NZE buildings can achieve higher occupancy rates, rental premiums, and increased employee productivity. The document also outlines a four-step process for transitioning existing buildings to NZE operation and promotes the NZE Leasing Best Practice Guide to scale adoption in the commercial sector.

Boulder Commons is a 100,000 square foot multitenant project in Boulder, Colorado, that demonstrates the feasibility of net-zero energy (NZE) commercial real estate. The project achieved NZE through a combination of high-efficiency building systems and 575 kW of solar PV, including an innovative vertical installation on the southeast façade. The developer, Morgan Creek Ventures, implemented a specific NZE lease structure that includes plug load budgets for tenants and annual recommissioning to ensure performance. Financially, the project saw a 12% hard cost premium (excluding solar) but expects higher net cash flow due to increased tenant retention and a lower capitalization rate at the point of sale.

RMI implemented a parking cash-out program at its Boulder Commons North office, allowing employees to choose between a parking spot or cash to support alternative commuting. During a three-month pilot, 64% of employees opted for the cash-out, with 60% of those switching from single-occupancy vehicles to biking, walking, or busing. This shift is estimated to avoid 950 single-occupancy vehicle miles and 415 kg of carbon emissions weekly. The program leverages a 'green-lease' structure that decouples parking costs from rent, demonstrating that transportation demand management can provide cost savings for employers and developers even in smaller urban settings.

The document argues that federal light-duty vehicle standards set by the EPA and NHTSA in 2012 provide significant financial and environmental gains for Colorado. By 2030, the average Colorado household is projected to be $2,700 richer due to gas savings. To date, Colorado has saved $550 million, and the standards have eliminated global warming emissions equivalent to three times those required to provide electricity to Boulder. Nationally, these standards are expected to increase GDP by up to $30 billion and create 650,000 full-time jobs by 2030.

The Door-to-Downtown (d2d) pilot in Boulder, Colorado, tested a public-private partnership to shift residents and visitors from personal vehicles to shared mobility services. By offering a $5 discount on inbound trips, the program attracted 5,400 registrants and generated nearly 2,500 trips, primarily peaking on Fridays. The pilot demonstrated that MaaS can alleviate downtown parking pressure and provide a scalable model for future electric and autonomous vehicle integration to meet carbon reduction goals.

The City of Boulder implemented the 'Door to Downtown' (d2d) pilot program, offering $5 discounts on rides via Lyft, Uber, and zTrip to encourage the use of mobility services over personal vehicles. The program aims to address immediate parking challenges and test the long-term price elasticity of demand for Mobility as a Service (MaaS). By bringing the cost of rideshare services down to the estimated $0.60 per mile cost of owning and operating an internal-combustion vehicle, the pilot explores whether consumers will switch to shared mobility when it reaches cost parity with car ownership.

The December 2016 cold air outbreak in the United States was found to be a common winter occurrence and not evidence that global warming is increasing the extremity of cold weather. Analysis of stations in Boulder, Colorado, and New Orleans, Louisiana, indicates that cold extremes are generally decreasing in intensity, particularly in New Orleans where the coldest day of the year is 3.2°F warmer than a century ago. The study concludes that while northerly wind patterns show no significant trend, the Arctic source regions for this cold air are warming rapidly, leading to a general decrease in the intensity of such outbreaks in both observations and climate models.
