There has been a decline in greenhouse gas (GHG) emissions per capita in all world regions since the 1990s. In developing countries, this decline has been attributed to population growth and an increase in absolute emissions, while in developed countries, the trend is mainly due to a decrease in absolute emissions combined with minor population changes.

The lack of equal globally binding GHG’s emission reduction targets is currently leading to a set of diverging GHG’s emission prices across the world (or even no price for GHG’s emission in some regions). This may result in distortions with direct implications on competitiveness of the industries in regions with strict climate policies (as the European Union) and can cause the issue of carbon leakage. Carbon leakage is defined as ‘the increase in emission outside a region as a direct result of the policy to cap emission in this region’.

There has been a decline in greenhouse gas (GHG) emissions per capita in all world regions since the 1990s. In developing countries, this decline has been attributed to population growth and an increase in absolute emissions, while in developed countries, the trend is mainly due to a decrease in absolute emissions combined with minor population changes. This paper aims to delve into the intricacies of global GHG emissions, with a spotlight on the agricultural sector. This paper assesses the patterns and reasons behind the decline in GHG emissions per capita since the 1990s across different regions. In particular, it addresses the concept of the "sustainable intensification of agriculture" and the debate between intensive vs. less-intensive production in the context of GHG emissions. Despite having high emissions per hectare, we argue that European countries show lower emissions in relation to production value, highlighting the region's production intensity and efficiency. Compelling visual data representations and references from significant international bodies, such as the IPCC and EEA, bolster the paper's findings and conclusions. [ABSTRACT FROM AUTHOR]

The article presents how the concept of the Carbon Border Adjustment Mechanism (CBAM) is reflected in the regulation recently adopted in the EU and what possible effects CBAM may cause. The authors begin with explaining the reasons for the introduction of CBAM. Next, they briefly describe what obligations arise from the mechanism for entities and EU Member States and compare this mechanism to the EU ETS. The challenges facing the mechanism and the possible effects of its implementation are then examined. In the final section, the authors assess the economic impact of the CBAM on the Polish economy, taking into account changes in the price levels, in the value of production, exports and imports, GDP and household consumption in the horizon of 2030. The projection was carried out using the Carbon Regulation Emission Assessment Model (CREAM), which is the static general equilibrium model developed in the Centre for Climate and Energy Analyses (CAKE) at the National Centre for Emission Management (KOBiZE).

CdII is a major genotoxic agent that readily displaces ZnII in a multitude of zinc proteins, abrogates redox homeostasis, and deregulates cellular metalloproteome. To date, this displacement has been described mostly for cysteine(Cys)‐rich intraprotein binding sites in certain zinc finger domains and metallothioneins. To visualize how a ZnII‐to‐CdII swap can affect the target protein's status and thus understand the molecular basis of CdII‐induced genotoxicity an intermolecular ZnII‐binding site from the crucial DNA repair protein Rad50 and its zinc hook domain were examined. By using a length‐varied peptide base, ZnII‐to‐CdII displacement in Rad50's hook domain is demonstrated to alter it in a bimodal fashion: 1) CdII induces around a two‐orders‐of‐magnitude stabilization effect (log K12ZnII =20.8 vs. log K12CdII =22.7), which defines an extremely high affinity of a peptide towards a metal ion, and 2) the displacement disrupts the overall assembly of the domain, as shown by NMR spectroscopic and anisotropy decay data. Based on the results, a new model explaining the molecular mechanism of CdII genotoxicity that underlines CdII's impact on Rad50's dimer stability and quaternary structure that could potentially result in abrogation of the major DNA damage response pathway is proposed.

The lack of equal globally binding GHG's emission reduction targets is currently leading to a set of diverging GHG's emission prices across the world (or even no price for GHG's emission in some regions). This may result in distortions with direct implications on competitiveness of the industries in regions with strict climate policies (as the European Union) and can cause the issue of carbon leakage. Carbon leakage is defined as 'the increase in emission outside a region as a direct result of the policy to cap emission in this region'. This paper is the first part of the set of two analysis aiming at the carbon leakage assessment. In the following paper (aimed to be published this year), we will assess the impact of free allowances for emission intensive trade exposed industries (EITE) and the NDCs in the rest of the world countries - for the sake of brevity, we decided to remove these results from the current paper, but they will be presented later this year. The purpose of this paper is to assess the possible scale of the carbon leakage using different assumptions and policy scenarios and identify channels to efficiently prevent the carbon leakage phenomenon. The analysis has been carried out using the computable general equilibrium d-PLACE model developed within the Centre for Climate and Policy Analysis (CAKE).2 Our model is a recursive dynamic multi-regional and multi-commodity tool in which emissions are modelled in great detail, for example, the process and each fossil fuel combustion related emission are modelled separately. Furthermore, the big advantage of the applied model is a very detailed modelling of EU ETS as well as non-ETS emission targets. In the paper, the simulations using two versions of model was presented - with and without endogenous technical change to elaborate on how the assumptions on technical change affect the modelling results and consequent scale of the carbon leakage. Moreover, this paper aims mainly at the assessment of different channels of carbon leakage; therefore, we do not take into account either NDCs in the rest of the world or free allowances for emission intensive trade exposed sectors. These problems will be handled in the next paper, aimed to be published later this year. Using the above mentioned CGE (computable general equilibrium model, we captured the main factors, that determine the carbon leakage rates. We assessed the contribution of three channels - demand channel, competitiveness channel and carbon intensity channel to the risk of carbon leakage. It turned out that carbon intensity channel and competitiveness channel are the most important, while demand channel contributes to changes in GHG's emission only in the most restrictive scenario. Moreover, energy channel was further decomposed to the impact of sectoral structure and influence in emission intensity within each sector - the impact of these two channels is also similar, but dependent on the analysed scenario. Such a decomposition allowed us to determine the main channels through which the carbon leakage occur and pursue relevant policy recommendations. [ABSTRACT FROM AUTHOR]
