Removing carbon dioxide from the atmosphere
The agricultural sector plays a decisive role in tackling climate change. GERICS explores what actors of the agricultural sector think of removing carbon dioxide and what support they need from science. Many countries have the goal of reaching the net-zero emission target. This means any human activity releasing greenhouse gas emissions into the atmosphere must be counterbalanced by an equivalent amount being removed. But how is that supposed to work? First and foremost, we must reduce our greenhouse gas emissions as much as possible. However, for the emissions that are hard to abate, such as from the cement industry or livestock, removing carbon dioxide (CO2) from the atmosphere has become an essential part of the package reaching the net- zero emissions target.

The emissions of carbon dioxide (CO2) are an objective result of the civiliza-tional development of the world. Ensuring a steady decline in CO2emissions in the condi-tions of economic growth and social welfare requires a structural analysis of systemic de-pendencies. The purpose of the study is to investigate the contribution of different socio--economic factors to the changes in carbon dioxide emissions. A decomposition analysis is performed to examine the pace of CO2emission changes in relation to changes in: emissivi-ty of gross domestic product (GDP), productivity of man-hours, number of employees and working time per employee. Statistical data refer to the Polish economy in the period of 1990—2015.The results provided in this paper show that the economic growth in Poland had the most noticeable contribution to CO2emission changes. The solid growth of economy was ac-companied by decreasing emissivity of GDP. The increase in the labour supply, observed in some periods, contributed to the relative growth of that factor in pollutant emission changes. Considering the growing labour productivity, efforts to increase employment should be correlated with decreasing number of working hours per employee.

[EN] Hydrogenation of carbon dioxide is considered as a viable strategy to generate fuels while closing the carbon cycle (heavily disrupted by the abuse in the exploitation of fossil resources) and reducing greenhouse gas emissions. The process can be performed by heat-powered catalytic processes, albeit conversion and selectivity tend to be reduced at increasing temperatures owing to thermodynamic constraints. Recent investigations, as summarised in this overview, have proven that light activation is a distinct possibility for the promotion of CO2 hydrogenation to fuels. This effect is particularly beneficial in methanation processes, which can be enhanced under simulated solar irradiation using materials based on metallic nanoparticles as catalysts. The use of nickel, ruthenium and rhodium has led to substantial efficiencies. Light-promoted processes entail performances on a par with (or even superior to) those of thermally-induced, industrially-relevant, commercial technologies. ; The author thanks the Spanish Government (Ministerio de Economía y Competitividad, MINECO) for financial support via a project for young researchers (CTQ2015-74138-JIN), and the ''Severo Ochoa'' programme (SEV 2012-0267).

Futures contracts are exchange-traded financial instruments that enable parties to fix a price in advance, for later performance on a contract. Forward contracts also entail future settlement, but they are traded directly between two parties. Futures and forwards are used in commodities trading, as producers seek financial security when planning production. We discuss the potential use of futures contracts in Carbon Dioxide Removal (CDR) markets; concluding that they have one principal advantage (near-term price security to current polluters), and one principal disadvantage (a combination of high price volatility and high trade volume means contracts issued by the private sector may cause systemic economic risk). Accordingly, we note the potential for the development of futures markets in CDR, but urge caution about the prospects for market failure. In particular, we consider the use of regulated markets: to ensure contracts are more reliable, and that moral hazard is minimised. While regulation offers increased assurances, we identify major insufficiencies with this approach—finding it generally inadequate. In conclusion, we suggest that only governments can realistically support long-term CDR futures markets. We note existing long-term CDR plans by governments, and suggest the use of state-backed futures for supporting these assurances.
