The text emphasizes that while climate change is a global challenge requiring national commitments like the Paris Agreement, effective action is often anchored at the subnational level. It highlights the Under2MoU alliance, co-founded by Baden-Württemberg and California, as a model for regional leadership. The author, Franz Untersteller, details Baden-Württemberg's specific goals—including a 90% emission reduction by 2050—while noting that regional success is limited by the need for stronger regulatory frameworks from the German federal government and the European Union.

The Union of Concerned Scientists identifies several California communities, including Alameda and San Mateo, that face 'chronic flooding'—defined as high tides flooding 10% or more of usable land at least 26 times per year—by the end of the century. Under a high-emission scenario, these impacts could arrive by 2080. Critical national security infrastructure, such as the Naval Station San Diego, is also at risk. The document argues that limiting global warming to 1.8°C could prevent any California community from reaching the chronic flooding threshold by 2100 and urges immediate policy reforms regarding coastal development, disaster funding, and population relocation.

The Union of Concerned Scientists (UCS) identifies several California communities, including Alameda and San Mateo, that face 'chronic inundation'—defined as high tide flooding 10% or more of usable land at least 26 times per year—by 2100 under intermediate sea level rise scenarios. In a high-rise scenario, this timeline accelerates to 2080. The report highlights specific risks to military installations in San Diego and developing neighborhoods in San Francisco. However, the document notes that limiting warming to approximately 1.8°C (the 'low' scenario) could prevent any California community from reaching the 10% chronic inundation threshold by the end of the century. To address these risks, the UCS advocates for halting risky coastal development, enhancing disaster response funding, and creating new policies for managed retreat and relocation.

The 2016 assessment reveals a significant decline in elephant ivory availability in historical physical markets like New York City, San Francisco, and Los Angeles, potentially due to state-level bans. However, the market appears to be pivoting toward online platforms and states without strict regulations, such as Washington, DC and Oregon. The report documents 1,589 items in physical retail and 2,056 items across six online platforms, noting widespread confusion among vendors regarding legal exemptions and a trend of mislabeling ivory as 'bone' or 'mammoth' to evade detection.

India can reduce its passenger road-based energy demand by 64% and carbon emissions by 37% by 2030 by adopting a 'transformative' mobility paradigm. This approach emphasizes a shift from private vehicle ownership to a system based on shared, electric, and connected services. The report outlines a three-phased implementation strategy (2017–2032) focusing on system integration, shared infrastructure, and scaled manufacturing. Key recommendations include establishing a central data sharing institution, implementing 'feebates' and ZEV credits, and developing standardized swappable batteries for 2- and 3-wheelers. The proposed 'change model' utilizes a national learning platform and regional 'lighthouse' change labs to scale economically viable solutions from the state to the national level.

The document argues that promoting active travel—defined as walking, cycling, and public transit—creates a 'quadruple win' by reducing chronic disease, improving air quality, slowing climate change, and increasing health equity. It provides a framework for health professionals to encourage patients to integrate physical activity into their daily routines and to advocate for urban planning policies, such as the '5 Ds' of community design (density, land use diversity, design, destination accessibility, and distance to transit). A significant portion of the guide focuses on the Growth Plan for the Greater Golden Horseshoe in Ontario, explaining how intensification and complete community planning can facilitate a shift away from automobile dependence.

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 Kit Carson Electric Cooperative (KCEC) aims to serve its 29,000 customers during the summer peak with 100 percent solar power by 2023. To achieve this, KCEC exited a restrictive contract with Tri-State Generation and Transmission via a $37 million exit fee funded by Guzman Renewable Energy Partners. The cooperative plans to deploy over 30 MW of community-scale solar, consisting of multiple 1 MW arrays, to maintain system reliability and lower costs through standardization. KCEC expects solar prices as low as 4.5 cents/kWh, providing rate certainty and local economic development opportunities.

California is experiencing significant damages from climate change, including increased heat-related mortality, more frequent and severe wildfires, and rising sea levels. The state faces critical water shortages, record-low snowpacks in the Sierra Nevada, and a high risk of extinction for 83 percent of its native freshwater fish species.

California has successfully decoupled economic growth from greenhouse gas emissions through a policy blend of performance standards and a broad cap-and-trade program. Since 2006, the state has seen a 7 percent decline in emissions while experiencing robust job growth, particularly in the green technology sector. Key achievements include significant adoption of plug-in electric vehicles, a growing renewable energy portfolio, and the influence of its building and appliance codes on other U.S. states and federal policy. The state is now shifting focus toward 2030 targets, including a 50 percent renewable portfolio standard and a goal to reduce economy-wide emissions by 40 percent below 1990 levels.

The report evaluates the energy impact of Hunter Douglas insulating honeycomb shades using whole-building simulations in nine U.S. cities. It finds that these shades can significantly reduce heating and cooling energy consumption, particularly in existing homes, while improving operative temperatures and reducing peak electrical demand. The study emphasizes that savings are highly dependent on the operation schedule and window orientation, with west-facing windows being critical for peak demand reduction in summer.

The 'Green and Smart Town Development Guidelines' by China Development Bank Capital outlines 12 measurable green guidelines across urban form, transport, and energy/resources, alongside six smart city strategies. The guide aims to reduce urbanization costs from 8.6% to 6.8% of GDP by implementing compact development, transit-oriented design, and resource efficiency. It provides specific benchmarks, such as limiting block sizes to 2 hectares and requiring 70% of buildings to meet MOHURD one-star green standards, supported by international case studies from Portland, Stockholm, and Copenhagen.

The document outlines the transition to Mobility as a Service (MaaS), where on-demand, multimodal transportation replaces the dominance of personally owned vehicles. It identifies interoperable transit data (ITD) as the critical infrastructure needed to enable seamless trip planning and payment. The report details barriers to this transition—including regulatory gaps, payment fragmentation, and inconsistent data standards—and proposes solutions such as public-private partnerships, the development of integrated payment portals, and the implementation of 'commuting as a service' pilot projects.

The report analyzes how battery energy storage can provide thirteen different services across three grid levels: transmission, distribution, and behind-the-meter. It argues that while single-use batteries are often underutilized and economically unviable, 'stacking' multiple services—such as combining demand charge reduction with wholesale grid services—can make storage a cash-positive investment. Through four U.S. case studies, the report demonstrates that behind-the-meter systems are technically capable of providing the widest array of services, though significant regulatory barriers currently hinder this potential.

The document examines how Proposition 39, which provides an estimated $2.75 billion for energy efficiency and clean energy in public buildings, can be targeted to maximize energy savings in California schools. It identifies that while many districts can access low-cost private capital for short-payback projects like lighting, they lack the technical capacity to vet proposals and the funding to pursue deeper, more costly energy-saving measures. The authors recommend using Proposition 39 funds for impartial technical assistance, matching grants for high-impact projects, and targeted support for financially distressed or small districts.

The document details the U.S. effort to reach a goal of one million electric vehicles by 2015 through the development of 'deployment communities' and infrastructure. It describes federal initiatives like the Transportation Electrification Initiative and Clean Cities, regional efforts such as the Northeast Electric Vehicle Network, and commercial fleet adoptions by companies like Frito Lay and General Electric. It also lists specific legislative proposals aimed at increasing consumer tax credits and funding for community deployment and fleet upgrades.

The authors developed a framework combining the Water Evaluation And Planning (WEAP) system and the SALMOD population dynamics model with climate data to identify critical temperature and streamflow thresholds for spring-run Chinook salmon in California. This approach aims to evaluate management adaptations to protect salmon, which are vulnerable to rising summer river pool temperatures before autumn spawning.

The document outlines the job creation potential of the clean energy economy, citing that renewable energy (RE) and energy efficiency (EE) industries created over nine million jobs in the U.S. in 2007. It provides specific employment projections for various technologies, including wind, solar, bioenergy, and geothermal, across U.S. states and international markets such as Germany, Brazil, and India. The text also compares these figures to employment trends in the fossil fuel and nuclear sectors and details U.S. legislative efforts, such as the Green Jobs Act of 2007 and the American Recovery and Reinvestment Act of 2009, to support workforce training and clean energy deployment.

The document asserts that the United States must reduce greenhouse gas emissions by at least 80 percent below 2000 levels by 2050 to avoid severe climate impacts. It argues that the cost of action is small relative to the global and national economy, while the cost of inaction is significantly higher, citing potential losses of over 3.6% of U.S. GDP annually by 2100. The text advocates for a policy mix of market-based cap-and-trade systems and sector-specific incentives, warning that 'safety valves' or price caps would undermine investment in new energy technologies.

The report identifies non-hardware balance of system costs, which can reach 40% of installed system costs, as a significant barrier to rooftop solar adoption. It recommends the adoption of standardized frameworks such as the Solar ABCs Expedited Permit Process for permitting, the IREC Model Interconnection Procedures for grid connection, and the NNEC design criteria for net metering. The document highlights Colorado as a leader in solar-friendly policies, citing the Fair Permit Act's fee caps and the state's removal of net metering capacity limits for systems up to 120% of annual on-site consumption.
