Mangrove forests store and sequester large area-specific quantities of blue carbon (Corg). Except for tundra and peatlands, mangroves store more Corg per unit area than any other ecosystem. Mean mangrove Corg stock is 738.9 Mg Corg ha−1 and mean global stock is 6.17 Pg Corg, which equates to only 0.4–7% of terrestrial ecosystem Corg stocks but 17% of total tropical marine Corg stocks. Per unit area, mangroves sequester 179.6 g Corg m−2a−1 and globally about 15 Tg Corg a−1. Mangroves sequester only 4% (range 1.3–8%) of Corg sequestered by terrestrial ecosystems, indicating that mangroves are a minor contributor to global C storage and sequestration. CO2 emissions from mangrove losses equate to 0.036 Pg CO2-equivalents a−1 based on rates of C sequestration but 0.088 Pg CO2-equivalents a−1 based on complete destruction for conversion to aquaculture and agriculture. Mangrove CO2 emissions account for only 0.2% of total global CO2 emissions but 18% of CO2 emissions from the tropical coastal ocean. Despite significant data limitations, the role of mangrove ecosystems in climate change mitigation is small at the global scale but more significant in the tropical coastal ocean and effective at the national and regional scale, especially in areas with high rates of deforestation and destruction.

The article aims at ascertaining the relationship between indicators affecting the green economic growth of the Eurozone countries. Despite extensive research, scientists have not yet found a clear answer as to whether economic growth and climate change mitigation can be aligned. Another important aspect of the study was to investigate the possible effect of environmental policies on macroeconomic variables such as GDP, investment, employment, and trade. The authors of the article applied the PVAR econometric model to measure the impact of energy consumption, CO2 emissions, and some of the macroeconomic indicators on GDP growth in 19 countries of the Eurozone for years 2000–2016.Based on the results, we cannot yet state explicitly that economic growth in the Eurozone countries has been decoupled from climate change mitigation; however, green transition is on the right track.

Soil, in addition to storing is a source of CO2 to the atmosphere emitted by soil respiration, mainly due to land use change. The objective of the research was to evaluate soil respiration in different uses and quantify its CO2 emissions at two different times of the year, as well as estimate the storage of this to make a balance to establish strategies that allows with the climate change mitigation. Using a closed dynamic chamber placed on the soil and integrated with an infrared gas analyzer measured the CO2 emission every 30 min, as well as temperature and moisture of the soil with sensors. Three land uses (agroforestry, forestry and agricultural) and two seasons of the year (summer and winter) were analyzed for 24 continuous hours at each site. Positive correlation between ambient temperature and soil respiration was found to exist. The agricultural system stores low carbon content in the soil (50.31 t C ha-1) and emits 9.28 t of C ha-1 in the highest temperature season, in contrast to a natural system that emits 3.98 t of C ha-1 and stores 198.90 t of C ha-1. The balance sheet reflects the need to know CO2 emissions to the atmosphere from soils and not just warehouses. Having scientific support from the ground to the atmosphere is an important step in decision-making that will contribute to climate change mitigation.

Active travel (walking, cycling or scooting for transport) is considered a healthy and sustainable form of getting from A to B. The net effects of active travel on mobility-related carbon dioxide (CO2) emissions are complex and remarkably under-researched across a wide range of settings. This paper seeks to provide a summary of research on active travel as a low carbon mobility option in context of the climate emergency. Key gaps are identified and discussed. The paper concludes with a projection of future research.

Mangrove forests store and sequester large area-specific quantities of blue carbon (Corg). Except for tundra and peatlands, mangroves store more Corg per unit area than any other ecosystem. Mean mangrove Corg stock is 738.9 Mg Corg ha−1 and mean global stock is 6.17 Pg Corg, which equates to only 0.4–7% of terrestrial ecosystem Corg stocks but 17% of total tropical marine Corg stocks. Seagrasses sequester more Corg per unit area than mangroves (179.6 g Corg m−2·a−1) but twice the Corg sequestered by mangroves globally (15 Tg Corg a−1). Mangroves sequester only 4% (range 1.3–8%) of Corg sequestered by terrestrial ecosystems, indicating that mangroves are a minor contributor to global C storage and sequestration. CO2 emissions from mangrove losses equate to 0.036 Pg CO2-equivalents a−1 based on rates of C sequestration but 0.088 Pg CO2-equivalents a−1 based on complete destruction for conversion to aquaculture and agriculture. Mangrove CO2 emissions account for only 0.2% of total global CO2 emissions but 18% of CO2 emissions from the tropical coastal ocean. Despite significant data limitations, the role of mangrove ecosystems in climate change mitigation is globally insignificant but may be more significant and effective at the national and regional scale.
