When it comes to addressing climate change, there are two well-known strategies to make the world a better place. One of them is mitigation, which involves trying to stop the climate from worsening anymore. The other strategy is adaptation, which entails finding ways to cope or live with the change in climate without stopping the change itself. And sure, there is another option: no action, which involves doing nothing- it’s the most costly of them all. Let us focus on mitigation.
Mitigation is the process of slowing down climate change by minimising the amount of greenhouse gases released in the air. A classic example of mitigation is the planting of CO2-trapping trees.
Current Mitigation Techniques
While some mitigation strategies are cheap and short-term, others are expensive and long-term when it comes to implementation. The following are the mitigation techniques currently (as of 2018) implemented in various economic sectors.
- Use of gas instead of coal
- Use of renewable power and heat, including geothermal energy, bioenergy, wind energy, and solar energy
- Invention of more fuel-efficient automotives (cleaner diesel and hybrid vehicles)
- More usage of rail instead of road transport
- Increased walking, cycling, and other non-motorised ways of transport
- Enhanced crop land management to facilitate carbon storage in the soil
- Degraded land restoration
- Improved manure management to minimise emission of CH4
- Material recycling
- Material substitution
- Enhanced heat recovery
- Reduced deforestation
- Enhanced forest management
- Organic waste composition
- Treatment of waste water
- Waste minimisation
- Waste recycling
- Increased recovery of landfill methane
There seems to be no scarcity of GHG mitigation techniques. However, despite massive technological advancements taking place in the world today, there is no single fix for carbon emissions. Applying more than one strategy makes the results even better- the power of synergy, as they say.
