Abandoned lands formed in the place of former arable lands occupy considerable areas in the steppe zone and are a basic reserve for the restoration of the steppe biome in Russia. Taking into account the secondary steppe ecosystems developed in the place of the abandoned lands, the total carbon dioxide sink in the steppe zone of Russia can reach 92-121 Mt С per year. This is comparable to the СО2 sink in the managed forests of the Russian Federation (96 Mt/yr) and accounts for 10-20% of the total sink of СО2 in the terrestrial ecosystems of Russia. To increase the sink potential on the territory of the Russian Federation, the natural and restored steppe ecosystems should be preserved.

Based on the latest national carbon dioxide emissions data released from the International Energy Agency (IEA), the carbon dioxide emissions trends of BRICS were analyzed in three aspects: the total carbon dioxide emissions, the emission intensity calculated using purchasing power parties (PPP) and per capita carbon dioxide emissions. The results show that the total carbon dioxide emissions among BRICS presented an increasing trend in different extent. On the other hand, the emission intensity calculated using PPP of BRICS showed a decreasing trend. The per capita carbon dioxide emissions of BRICS also presented an increasing trend in different extent. The Russian Federation and South Africa’s per capita carbon dioxide emissions were higher than the World’s average level, whilst those of India, Brazil and China were lower than the World’s average level, which is far less than the level of the OECD countries.

Abstract Carbon dioxide fluxes between ecosystems of the Earth are presented. It was shown that intensifying its absorption of terrestrial ecosystems by 3.2% would prove sufficient to neutralize carbon dioxide emissions from the combustion of fossil fuels and cement production. It was shown that Polish forests absorb 84.6 million tons of CO2/year, that is 26% of emissions from fossil fuel combustion and cement production, while agricultural crops absorb 103 million tons of CO2/year. Total carbon dioxide sequestration by forests and agricultural crops amounts to 187.5 million tons of CO2/year, which is tantamount to 59% of emissions from fossil fuel combustion and cement production. Forestation of marginal soils would further increase carbon dioxide absorption in Poland by 20.6 million tons of CO2/year. Moreover, if plants were sown in order to produce green manure - instead of leaving soil fallow - sequestration could still be boosted by another 6.2 million tons of CO2/year.
