Carbon Emission Mitigation Efforts in Kenya
Kenya, like many other countries, has been affected by the negative impacts of climate change, such as irregular weather patterns and increasing extreme weather events, due to increasing greenhouse gas (GHG) emissions. Kenya, which has a population of 50.6 million people and the biggest economy in East Africa, is the centre of the region’s trade, finance, and communications. The nation’s economy is heavily reliant on tourism and agriculture, both prone to climate variability and extreme weather events.

Carbon Emission Reduction Efforts and Government Subsidy Strategies
Government subsidies positively influenced the carbon emission reduction efforts and marketing efforts of supply chain members and could increase the overall profit of the supply chain and the overall welfare of society. Meanwhile, social welfare increased first and then decreased with the subsidy, and there was a maximum value. Within a certain threshold, when the market demand was sensitive to carbon emission reduction efforts, it was more beneficial to subsidize manufacturers, and when it was sensitive to marketing efforts, subsidizing retailers was more beneficial. Regardless of the subsidy situation, an optimal subsidy rate exists among supply chain members. Meanwhile, adjusting government subsidy measures can decrease the profit gap between supply chain members, and it provides potential possibilities for cooperation among supply chain members.

Carbon Footprint
A carbon footprint is “a measure of the exclusive total amount of carbon dioxide emissions that is directly and indirectly caused by the activities of an individual or is accumulated over the life stages of a product”.

Carbon Footprint Initiatives
One of the most significant environmental aspects is the issue of climate change due to carbon dioxide emissions generated by human activities. Given the importance of this topic, this paper gathers initiatives and methodologies that have been undertaken to calculate and reduce CO2 emissions and climate change effects. After studying these methodologies, their strengths and opportunities for further enhancement have been analyzed.

Carbon Footprint Reduction and Climate Change Mitigation
Since the Industrial Revolution, human economic activity and the global development of society in general have been heavily dependent on the exploitation of natural resources. The use of fossil fuels, deforestation, the drainage of wetlands, the transformation of coastal marine ecosystems, unsustainable land use, and many other unbalanced processes of human activity have led to an increase both in the anthropogenic emissions of climate-active gases and in their concentration in the atmosphere. It is believed that over the past ~150 years these phenomena have contributed to an increase in the global average temperature in the near-surface layer of the atmosphere by ~1 °C. Currently, the most pressing tasks facing states and scientific and civil societies are to reduce anthropogenic CO2 emissions and to limit the global air temperature increase. In this regard, there is an urgent need to change existing production systems in order to reduce greenhouse gas emissions and to sequester them.

Carbon Footprint Reduction through Modern Supply-Chain Measures
The worldwide Sustainable Development Goals (SDGs) for smart cities and communities focus significant attention on air quality and climate change. Technology and management can reduce fossil fuel dependence in smart cities’ energy supply chains (SC). A sustainable smart city and reduced carbon emissions require coordinated technology and management with appropriate infrastructure.

Carbon in Agricultural Soil
Carbon in agricultural soils is chemically classified as either soil organic carbon (SOC) or soil inorganic carbon (SIC). Globally, the naturally occurring SOC and SIC pools are estimated to be 1500 Gt C and 950 Gt C, respectively. The SOC includes humus, decomposed plant and animal residues, charcoal and microorganisms. The SIC pool includes primary and secondary carbonates, such as calcite (CaCO3) and dolomite (CaMg(CO3)2), and can be classified into lithogenic and pedogenic carbonates. Lithogenic carbonates are the primary carbonates that refer to the detrital particle derived from the carbonate bedrock (especially limestone) that are formed in marine environments. Pedogenic carbonates refer to the secondary carbonates formed in the soil and is further classified as calcitic pedogenic carbonates (formed by calcite remobilization) and silicatic pedogenic carbonates (formed by silicate weathering). Calcitic pedogenic carbonates are derived from pre-existing carbonates; hence, it does not result in net carbon sequestration. On the other hand, carbonation of alkaline earth elements derived from silicate minerals results in net positive sequestration through the formation of silicatic pedogenic carbonates.

Carbon Literacy
Carbon Literacy is the awareness of climate change and the climate impacts of mankind's everyday actions. The term has been used in a range of contexts in scientific literature and in casual usage (see Research), but is most associated with The Carbon Literacy Project (CLP).

Carbon Materials as Cathode for Dual-Carbon Lithium-Ion Capacitors
Lithium-ion capacitors (LICs) have drawn increasing attention, due to their appealing potential for bridging the performance gap between lithium-ion batteries and supercapacitors. Especially, dual-carbon lithium-ion capacitors (DC-LICs) are even more attractive because of the low cost, high conductivity, and tunable nanostructure/surface chemistry/composition, as well as excellent chemical/electrochemical stability of carbon materials. Based on the well-matched capacity and rate between the cathode and anode, DC-LICs show superior electrochemical performances over traditional LICs and are considered to be one of the most promising alternatives to the current energy storage devices. The mismatch between the cathode and anode could be further suppressed by applying carbon nanomaterials.

Carbon Mineralization Technologies
Carbon dioxide is a byproduct of the industrial society. It is released into the atmosphere, which has an adverse effect on the environment. Carbon dioxide management is necessary to limit the global average temperature increase to 1.5 degrees Celsius and mitigate the effects of climate change, as outlined in the Paris Agreement.
