Climate Change mitigation refers to taking measures that reduce greenhouse gas emissions and enhance our ability to adapt to an evolving climate, such as transitioning to renewable energy sources, increasing energy efficiency and adopting practices such as regenerative agriculture or ecosystem conservation.
These actions often provide additional advantages; for example, restoring wetlands can reduce flood risks, buffer hurricanes and provide carbon storage benefits all in one go.
Reducing Greenhouse Gas Emissions
Individuals, communities and nations can all contribute to lowering greenhouse gas emissions in various ways. Simple actions like using less electricity and switching to renewable sources of power have a substantial effect while measures like decreasing fossil fuel usage in power plants or expanding climate-resilient mass transit can be more comprehensive in their reach.
Changes to agricultural practices can also have a dramatic effect. When livestock eat, they release methane and nitrous oxide – powerful greenhouse gases – into the atmosphere. Regenerative farming techniques like agroforestry or silvopasture that integrate trees and shrubs into cropslands have the ability to store five to ten times more carbon than pastures without trees cover.
UNDP provides countries with comprehensive technical assistance to meet their Paris Agreement targets for GHG emissions reductions, such as developing policies, standards and regulations; capacity building; knowledge mobilization; climate-smart projects piloted as pilot projects. UNDP plays an essential role in creating mitigation strategies such as renewable energy or energy efficiency initiatives that contribute towards this effort.
Adapting to Climate Change
Adaptation to climate change reduces risks from its impacts on people and nature, including responding quickly to impacts as they arise and capitalizing on opportunities such as longer growing seasons or increased food production in some locations.
Local governments, cities and communities all over the world have already begun working toward adaptation by building flood defenses, planning for higher temperatures and more frequent extreme weather events, and adapting their communications systems, business operations and government policies to make them more resilient.
Climate adaptation efforts, however, remain slow and unevenly implemented due to insufficient finance and governance capacities that impede their effective implementation.
Investing in Resilience
Though climate change mitigation requires global action, resilience requires local actions. Communities can strengthen their capacity to address its effects through local initiatives aimed at flood prevention and land use planning policies or supporting renewable energy options.
These initiatives may involve replacing fossil-fuel intensive building materials with more sustainable options such as recycled wood and concrete that don’t contribute to climate change; and expanding resilient mass transit networks that decrease both emissions and exposure to extreme weather events.
Rebuilding communities’ ability to respond to disasters reduces economic losses as well. According to research from the U.S. Chamber Foundation and others, each dollar invested in resilience strategies saves more than 30 times as much in future economic activity. A calibrated risk-informed approach can assist communities in investing in activities with maximum impact that align with national resilience goals.
Taking Action
As climate change impacts become more apparent, it is critical that all individuals take responsibility for mitigating its impacts. This doesn’t have to mean sacrificing life-style options but instead adopting meaningful change for a sustainable future.
Reducing energy use, shifting to renewables and strengthening carbon sinks such as forests and oceans are proven strategies for mitigating global warming, helping stabilize greenhouse gas levels while mitigating its most severe effects while maintaining economic development.
Each individual can reduce emissions by purchasing less electronics, shopping second-hand and using less plastic. They can invest their money in companies which prioritize reducing greenhouse gas emissions, waste and deforestation and support efforts to build sustainable communities by supporting small island developing states such as Comoros through UNDP’s solar minigrid program.
