The Fifth Carbon Budget – The next step towards a low
... We recommend that the fifth carbon budget is set at 1,765 MtCO2e, including emissions from international shipping, over the period 2028-2032. That would limit annual emissions to an average of 57% below 1990 levels, consistent with the cost-effective path to the 2050 target in the Climate Change Ac ...

Reforestation
Reforestation is the natural or intentional restocking of existing forests and woodlands that have been depleted, usually through deforestation.Reforestation can be used to improve the quality of human life by soaking up pollution and dust from the air, rebuild natural habitats and ecosystems, mitigate global warming since forests facilitate biosequestration of atmospheric carbon dioxide, and harvest for resources, particularly timber.The term reforestation is similar to afforestation, the process of restoring and recreating areas of woodlands or forests that may have existed long ago but were deforested or otherwise removed at some point in the past. Sometimes the term re-afforestation is used to distinguish between the original forest cover and the later re-growth of forest to an area. Special tools, e.g. tree planting bar, are used to make planting of trees easier and faster.
