A Tale of Four Cities on Infill, Emissions, & Political Nerve
The section discusses how four cities – Calgary, Edmonton, Minneapolis, and Vancouver – are approaching the challenge of accommodating more people in existing neighborhoods while reducing infrastructure costs, transport emissions, and building energy use. Calgary initially made a citywide move to allow for more housing diversity but later reversed it due to political backlash. The most effective emissions reductions come from adding homes in location-efficient, transit-supportive, walkable neighborhoods. The article emphasizes the importance of building energy-efficient, compact, mixed-use developments close to transit and amenities to reduce vehicle miles traveled, energy use, and CO2 emissions. Edmonton's zoning bylaw renewal focused on compact growth and climate implications, resulting in a reduction in greenhouse gas emissions. Minneapolis implemented zoning reform in 2019 allowing up to three units on low-density lots as part of a comprehensive plan to reduce greenhouse gas emissions from transportation. Vancouver has a more aggressive approach, allowing up to six dwelling units on a single lot and requiring zero-emissions equipment for heating in new buildings. The overall message is that comprehensive and integrated policies are needed to ensure low-carbon and politically durable urban development, with a focus on infill development, zero-emissions buildings, and strong transport policy.

Wired for Security: The EU’s Post-2030 Climate Architecture
The EU's 2040 climate target focuses on electrification powered by domestically generated renewable energy to reduce energy insecurity and dependence on imported fossil fuels. The post-2030 framework should prioritize clean electrification, with legislation like the Renewable Energy Directive and Energy Efficiency Directive playing key roles. The emphasis is on resilience and reducing exposure to global fossil fuel markets and geopolitical crises. Additionally, the EU Climate Law should be amended to include a legal obligation covering non-CO2 aviation effects to ensure sector-specific accountability and clear linkage to the 2040 trajectory. Carbon markets should complement national climate action, with revenues funding clean mobility and building renovation.

Balcony Solar Is Here, And It’s Not Just For Balconies
Lawmakers in states like Utah, Virginia, and Maine are introducing legislation to promote the use of balcony solar panels, which plug into household outlets and reduce electricity usage from the grid. The movement has faced hurdles in the US due to utility and landlord restrictions, safety concerns, and aging housing stock, but efforts are being made to address these issues. In Maine, where electricity rates have increased by 68% over the past five years, the potential benefits of balcony solar systems are being highlighted. Non-profit organization Bright Saver is advocating for balcony solar in the US, with kits already available in California, and supermarket chain Lidl is planning to carry plug-in solar panels at its UK stores. The Biden-era federal tax credits for household renewable energy improvements are seen as a helpful incentive for investing in solar energy. Companies are establishing a presence in solar-friendly states on the East Coast, using balcony solar kits to generate clean electricity and reduce monthly utility bills.
