Human technologies are not the only sources of low-carbon solutions. Cities can also shift the flow and management of their biological resources to reduce emissions, capture carbon, and provide numerous other benefits to a city.
Divert organic waste—including food waste, landscaping debris, and paper and cardboard packaging—from landfills. Organic materials anaerobically decompose in landfills and produce methane, one of the most potent greenhouse gases. Diversion from the landfill waste stream and subsequent proper composting can greatly reduce GHG impacts while producing a valuable landscaping and agriculture resource.
Well-designed urban forests can create powerful carbon sinks to remove carbon from the atmosphere and offset emissions. They can also reduce the urban heat-island effect, and therefore reduce energy use for cooling loads.
Shift menus to include more plant-based foods, creating opportunities to promote food options that cause fewer climate-related emissions while offering other health and related benefits. Conversely, diets high in meats, especially beef and pork, result in a much higher carbon footprint.
We are proud that the municipality of Cuiabá is leading this important initiative to improve public health and develop more sustainable programs. We know that sustainability is the essential commitment for any serious political management today.
‐Emanuel Pinheiro, Mayor of Cuiabá
Transitioning buildings toward net-zero energy makes buildings healthier and more comfortable, and smart approaches to retrofitting and new construction can create an economic boon for the city.
Carbon-free cities can provide more efficient and economic options that are tailored to different transportation needs—with no emissions—and that create vibrant urban spaces.
Leading cities are transforming electricity generation to carbon-free renewable energy by first committing to bold 100% renewable energy targets, then implementing comprehensive action plans.
Industry is a major employer and economic driver in many global cities, significantly shaping a city’s carbon emissions. Strategic partnerships with corporate residents can achieve economic and environmental solutions that benefit everyone.
Cities have an important role to play creating or expanding financing options and improving access to such financing.
City leaders and sustainability officers: take action today to put your city on a pathway to zero-carbon.
