Climate change mitigation entails actions which reduce greenhouse gas sources or enhance sinks, with key strategies for keeping global warming below 1.5 degrees Celsius involving scaling up clean energy production and transitioning our economies.
Restoring carbon-rich ecosystems like forests and shifting to regenerative food systems provide significant mitigation potential at relatively low costs.
Reduce Greenhouse Gas Emissions
Reducing emissions of heat-trapping greenhouse gases (GHGs) and other pollutant that disrupt Earth’s energy balance – such as black carbon particles – is essential to mitigating climate change. This can be accomplished using renewable energies, making existing equipment more energy-efficient or altering management practices and consumer behavior.
Energy emissions account for two-thirds of total anthropogenic GHG emissions and most come from fossil fuel combustion, making the energy sector one of the key targets for carbon capture and storage. Potential methods to mitigate GHG emission reduction include switching to alternative fuel vehicles, combined heat and power systems, carbon capture storage facilities or improving energy efficiency.
Commercial and residential sectors account for roughly 5 percent of direct greenhouse gas (GHG) emissions, mainly through fossil fuel usage for heating and cooling purposes. Electricity end use emissions are higher; from appliances and plug loads to large amounts consumed centrally generated electricity consumed in buildings. Emissions can be reduced through adopting new technology, improving insulation levels in buildings and producing more energy-efficient appliances.
Enhance Greenhouse Gas Sinks
Greenhouse gas (GHG) sinks are any objects or areas that absorb more carbon than they emit, such as forests, oceans or soil. Stable GHG concentrations in the atmosphere require that sources and sinks balance one another.
Natural carbon sinks currently absorb roughly 24 percent of human activity-generated CO2-equivalent emissions each year; however, many are expected to decline over time as droughty conditions reduce plant productivity and thus carbon capture capacity.
Clean coastal ecosystems play an integral part in mitigating* climate change by storing carbon in mangroves, salt marshes and seagrass beds – but these systems are often compromised due to coastal development activities or economic activities.
Adapt to Changing Climates
Adaptation involves making adjustments that mitigate climate change’s negative effects and take advantage of any opportunities presented by it. It could involve anything from insulate homes to cut energy consumption to planting drought-resistant crops or building seawalls against rising tides, and early warning systems which give people time to secure doors with sandbags, prepare food supplies or evacuate their home when an emergency situation arises.
Climate adaptation is a vital element of mitigation efforts and must be undertaken immediately if we want to avoid dangerous levels of warming. It involves everything from strengthening early warning systems, helping communities identify climate risks, restoring natural ecosystems to reduce flood risks or supporting local farmers to develop climate-smart agriculture, as well as projects such as creating land corridors to facilitate species migration – these efforts must all come together under local leadership with government support backing their implementation. Adaptation works best when driven from within communities with government backing behind it.
Promote Sustainable Development
Attaining climate change mitigation targets requires investing in cleaner technologies and shifting energy production and consumption patterns; however, the benefits far outweigh their costs by an overwhelming margin – especially regarding health co-benefits arising from emissions reductions helping mitigate pollution-related diseases (Markandya et al. 2013).
Reducing greenhouse gas emissions while improving energy security. Also creating jobs, stimulating economic development and spurring innovation.
Global leaders must accelerate climate-related measures while taking into account their effects on people’s lives and livelihoods. Climate-related disasters – such as heatwaves, wildfires, floods and drought – pose immense risk of injury, disease and death to millions worldwide; expose people to harmful air pollution; lead to water shortages which cause illness, malnutrition and mental health issues in low-income communities – especially low-income ones that require assistance to transition towards more sustainable, climate-resilient futures.
