Climate change mitigation encompasses any human activity which reduces emissions of greenhouse gases into the atmosphere or increases sinks for these gases, such as changing energy systems, protecting biodiversity or decreasing deforestation. Examples of such actions may include changing energy systems or restricting deforestation.
No matter who they are, everyone can play their part in mitigating climate change by adopting sustainable practices and supporting intelligent policies – thereby contributing to creating a brighter future.
Energy
At present, energy consumption accounts for most global greenhouse gas emissions. Switching away from fossil fuels such as coal to renewable sources like solar and wind power can significantly lower our carbon emissions.
Emissions generated during production contribute significantly to climate change. For instance, making and using new clothing, electronics or plastics generates carbon emissions at each step in production; purchasing secondhand items or repairing existing ones can help lower these emissions.
UNDP assists countries in mitigating climate change by leading them towards low-carbon and climate-resilient development pathways, including legislation, policies, standards and regulations, capacity building and knowledge dissemination. Furthermore, it supports projects that reduce emissions while increasing sinks – efforts crucial in keeping global warming below 1.5degC and avoiding irreversible climate impacts.
Transport
Greenhouse gases (GHGs) released into the atmosphere are contributing to global climate change. Transportation accounts for the bulk of GHG emissions; most come from fossil fuel sources like gasoline and diesel.
Electric public transit can help significantly lower GHG emissions when compared to private cars as it requires less energy and emits zero tailpipe pollution. Furthermore, sustainable freight transport solutions may also help decrease greenhouse gas emissions.
EPA’s SmartWay program is revolutionizing freight logistics across America by cutting emissions and cutting fuel costs for companies participating. These changes help improve air quality while supporting economic development; local governments are well suited to assess, exploit, and support these opportunities while helping improve energy efficiency, employ renewable energies, or promote alternative forms of transport.
Buildings
Buildings represent a substantial share of global energy consumption and emissions. Furthermore, this sector includes hard-to-abate industries like steel and cement manufacturing that make decarbonisation an important challenge.
The last IPCC assessment report revealed that greenhouse gas emissions from buildings could be reduced by 61% in 2050 relative to 2020 by implementing sufficiency approaches and efficiency measures; this represents an enormous mitigation opportunity in both developed and developing nations alike.
Green roofs can help reduce energy-intensive heating and air conditioning use while alleviating flooding risks. Furthermore, using local materials with zero environmental footprint can help mitigate temperature fluctuations; and adopting passive design principles can lower energy use while improving resilience against hazards.
Industry
Energy production accounts for the bulk of carbon emissions worldwide, making its transformation an obvious way to combat climate change. Transitioning towards renewables and improving energy efficiency rates are central, as are reducing fossil fuel use by switching to electric vehicles or protecting forests that act as natural carbon sinks.
Many manufacturing companies must abide by regulations designed to limit greenhouse gas emissions. This may involve restricting HFCs – with their global warming potential hundreds of times greater than CO2. Effective carbon management helps manufacturers meet compliance, minimize waste, and maximize efficiency – as well as gain a competitive edge in consumer markets where customers seek businesses who offer sustainability plans to combat climate change.
Agriculture
Climate-smart agriculture (CSA) seeks to address these goals by encouraging sustainable farming practices and offering relief in case of weather-related losses for farmers.
Climate-resilient crop varieties that can withstand extreme temperatures and drought conditions are becoming more widely available, helping reduce dependence on synthetic fertilizers and pesticides while conserving natural ecosystems.
Utilizing ecological principles such as avoiding over-plowed fields, planting cover crops and intercropping for biodiversity enhancement and livestock feed sources rotation can promote biodiversity while simultaneously improving soil health. This helps decrease fertilizer needs, prevent runoff of nutrient-laden water into streams and protect against flooding or drought conditions. Furthermore, decreasing food waste through healthier diet choices has been shown to significantly reduce methane and black carbon emissions.
