摘要

摘要 研究了降低俄罗斯经济碳强度的前景以及到 2060 年实现俄罗斯国民经济气候中和的可能性。根据历史外推法研究各种社会技术系统的发展,并通过比较俄罗斯和世界主要国家经济的碳指标动态,表明在被生物圈(主要是森林)吸收的情况下,人为温室气体排放的完全补偿如今仅在理论上是可能的。实现这一目标的条件是在俄罗斯从能源到林业的所有经济部门实施雄心勃勃的大规模改革计划。因此,在乐观的情况下,人均温室气体排放量具体指标的下降率应达到过去 50 年中全世界的最高值,即每年 1%。森林管理必须包括对不断增加的森林砍伐进行充分补偿,并将火灾造成的森林损失减少 50%,火灾目前是向大气排放温室气体的第二大来源(仅次于能源)。最有可能出现的情况是,人均具体温室气体排放量的下降率为 0.5%/年,并确保森林吸收能力的适度提高,这主要归功于森林气候项目的实施和野火排放量的减少。如果采用后一种方案,到 2060 年,温室气体净排放量可能达到约 7 亿吨二氧化碳(当量),这将需要国家以前所未有的规模发展碳捕获与封存产业,以实现气候中和。

Towards Climate Neutrality: Will Russian Forest Stand Against Energy?

The prospects for reducing the carbon intensity of the Russian economy and the possibility of achieving climate neutrality of the country’s national economy by 2060 are examined. Based on a historical-extrapolation approach to the study of the development of various socio-technical systems and by comparing the dynamics of carbon indicators of the economies of Russia and the leading countries of the world, it is shown that full compensation of anthropogenic greenhouse gases emissions when absorbed by the biosphere (primarily forests) is today rather only theoretically possible. The condition for this is the implementation of extremely ambitious large-scale reform programs in all sectors of the Russian economy, from energy to forestry. Thus, in an optimistic scenario, the decline rate of specific indicators of greenhouse gas emissions per capita should have the maximum values achieved in the world over the last 50 years, i.e. 1%/year. Forest management must include full compensation for increasing deforestation and a 50% reduction in forest losses from fires, which are currently the second (after energy) source of greenhouse gas emissions into the atmosphere. The most likely scenario is one in which the decline rate of specific greenhouse gas emissions per capita is 0.5%/year and a moderate increase in the absorption capacity of forests is ensured, mainly due to the implementation of forest climate projects and a reduction in wildfire emissions. If the latter scenario is implemented, net greenhouse gas emissions could amount to approximately 700 Mt CO2 (equiv.) by 2060, which will require the nation’s carbon capture and storage industry on an unprecedented scale to achieve climate neutrality.
