This study argues that improvements in material productivity might pave the way for a substantial reduction in emissions when adopted alongside energy productivity policies. We, therefore, compare the convergence pattern of material productivity with that of energy productivity from the mitigation perspective. To this end, we apply (un)conditional...

This study argues that improving material efficiency should be seriously considered as a mitigation policy objective alongside energy efficiency in order to meet the net-zero carbon targets and climate mitigation policies should be designed at the industry level based on the industry-specific needs and peculiarities. Therefore, by highlighting the...

This study investigates the main driving forces behind material use of the EU in the case of heterogeneity between member states with paying special attention to the comparison of domestic material consumption (DMC) with material footprint (MF).

Materials are of great importance as they are fundamentally integrated into many different critical topics, including green transition, technological progress, industrial emissions, and supply chains. Therefore, the amount of materials we demand and employ in the production process or how efficiently we use them become highly crucial. In this paper...

The share of emissions from materials has dramatically increased over the last decades and is projected to rise in the coming years. Therefore, understanding the environmental effect of materials becomes highly crucial, especially from the climate mitigation perspective. However, its effect on emissions is often overlooked and more attention is hea...

The share of emissions from materials has significantly increased over the last decades and is projected to rise in the coming years unless effective climate policies are developed. In this regard, understanding the environmental effect of material becomes highly crucial for achieving climate goals, especially from the climate mitigation perspectiv...

Mitigating industrial emissions is highly critical to achieving the net-zero emissions target. However, the fact that this sector is a part of a carbon-intensive production process makes it difficult to reduce emissions resulting from material production and use. The purpose of this study is to emphasize the importance of material efficiency for in...

The demand for materials has significantly risen in recent decades. This considerable increase in material demand has consequently led to a further increase in global emissions. In this regard, alongside widely-adopted energy efficiency policies, designing and implementing more comprehensive resource efficiency strategies particularly material effi...

In this paper, we discuss the role of material efficiency as a climate mitigation policy. For that purpose, we particularly focus on the degree of substitution between inputs, which is seen as one of the several material efficiency strategies, and explore substitution/complementarity possibilities between energy and material as well as between mate...

Recent studies investigating convergence in energy consumption at the sectoral level within a country suggest that aggregate energy consumption could mask considerable differential impacts that might be observed at the sectoral level. This study aims to contribute and complement the existing convergence literature with an attempt to analyze sectora...

Türkiye'nin en büyük ticari partnerinin AB olması nedeniyle Karbon Sınır Düzenlemesi (Carbon Border Adjustment-CBA) mekanizmasının uygulamaya konması, haliyle bu bloğa ihracat yapan birçok enerji-yoğun sektörü doğrudan etkileyecek. Ancak konu CBA'dan daha öte ve kapsamlı bir konu ve tüm sektörleri CBA harici de etkileyecek. Dolayısıyla Türkiye'de e...
