While clean technologies like offshore wind, carbon capture and solar power are clearly a huge part of any climate solution, addition measures including new incentives, laws, rules, bans, appliance standards, taxes and institutional innovations are also needed.
A new IIASA-led study shows that coordinated international action on energy-efficient, climate-friendly cooling could avoid as much as 600 billion tonnes CO2 equivalent of greenhouse gas emissions in this century.
The Hawai‘i State Senate announced that a bill protecting Hawai‘i’s coastal ecosystems was signed into law by Gov. David Ige. The enacted legislation includes a provision to ban further construction of sea walls and coastal hardening projects.
Backers of the bill say “the convergence of dense development along shorelines, increasing landward migration of shoreline due to sea level rise and other human and natural impacts, and extensive beach loss fronting shoreline armoring necessitated the revision of existing policies and regulations.”
Large-scale carbon dioxide removal (CDR), also referred to as “negative emissions”, is increasingly seen as a key component of climate change mitigation pathways that limit warming to 1.5C or 2C. While much of the climate literature tends to frame the various CDR approaches as novel and untested, in fact CDR has a longer and, in many ways, more tangible- and contested- history than this framing suggests, lessons from which are discussed in a recent paper in WIREs Climate Change.
