GHG Mitigation: What It Is and How It Works
GHG mitigation has several definitions. However, all seem to concur on one thing: GHG mitigation involves reducing the greenhouse gas concentration in the atmosphere. According to the United Nations, GHG mitigation refers to a human initiative aimed at reducing the sources or improving greenhouse gas sinks. This initiative includes things such as efficient use of fossil fuels, enhanced structure insulation, forest expansion, and increased usage of renewable forms of energy.
Do All Greenhouse Gases Have the Same Effect?
No. Various greenhouse gases differ in terms of their capacity to cause climate change. Each greenhouse gas has unique features, including radiative properties, lifespan in the atmosphere, and molecular weight, which determine its effect on the climate.
How is Mitigation Done?
There exists mitigation policies that target major economic sectors believed to be the key culprits when it comes to GHG emissions. The sectors include industry, transport, energy, agriculture, waste management, construction, and forestry. Typically, the policies require these sectors to engage in practices that reduce the emission of greenhouse gases into the air as much as possible. To encourage these practices, incentives and permits have proved to be useful.
However, since no country or region can single-handedly mitigate GHG emissions to significantly reduce global warming, mitigation is regarded as a global project in which every nation must play a role. Hence, the success of this initiative is hugely dependent on the cooperation of the world’s nations.
GHG Mitigation Challenges
In terms of development, the nations of the world are not on par. As a result, many countries (developing countries) feel that they are lagging behind because their industrialisation is still evolving. To them, GHG mitigation is tantamount to denying them development, which they see as the only way of catching up with their already industrialised cousins. In fact, many developing countries have demanded to be compensated for them to combat climate change through GHG mitigation.
