With the Rio+20 conference, held in 2012, at a global level, sustainability and balance interests were drawn up in the relationship between economic growth and environmental development, validating the efforts obtained in the fulfillment of the "Millennium Development Goals" and creating spaces for discussion of a green economic policy. In this sense, a dynamic vision for "The future we want" was set in motion.

This global discussion took shape with the "2030 agenda for sustainable development" of September 2015, in which 17 general objectives and 169 specific objectives were adopted that aim for the stability and equilibrium of the planet. Since their adoption, several governments and international agencies have worked to improve the social, environmental, economic and political conditions of each point of the planet. However, the process of the "Sustainable Development Goals" must understand and involve the nucleus of society: the home, and thus observe whether it really is an active actor in the face of the changes achieved/expected.

Households have natural differences according to their environment, capacities and deprivations, so it could be valid to suppose that households in developing countries respond to interests different from those of developed economies; for example: migratory dynamics, economic activities, uses of environmental resources, consumption and income, among others.

On this basis, this paper is interested in observing: a. exploring the definition of an indicator that measures sensitivity to household environmental quality and b. observing whether in developing countries this sensitivity to environmental quality may have effects on household consumption. If households have any type of impact due to the effect of environmental variables, you will want to indicate that public policies should focus on them as the primary object of attention and not as passive actors in a global political discussion.

Diffusion of innovation and technology is a key element in the economic growth of countries. Innovative behaviour of each country determines its stage in each adopter category and is essential in the development process, specially, in the reduction of the gap between developed and developing economies. Both innovation and its own diffusion depend on intersectoral relations of the economy. Different diffusion models have been developed to describe the innovation patterns between different adopter categories in the literature.
Technology innovation also plays a crucial role to achieve the climate goals agreed in different international commitments such as United Nations Framework Convention on Climate Change (UNFCC), and the Agenda 2030 of the United Nations. Innovation and environmental improvements have shown to be complementary, and international diffusion of technology performs an important role in the reduction of emissions worldwide. In this way, a faster diffusion of green technology is claimed in order to achieve environmental politic goals, and, in this way, address climate change.
Using series of input-output tables from 1970 to 2015, we explore diffusion patterns of innovation, technology and carbon intensity in key sectors for a group of advanced and developing countries (China, Germany, Spain, United States and United Kingdom). This paper makes use of a set of value chain indicators, such as the average propagation length, and upstream and downstream measures to analyse changes in their evolution and position throughout the period. The main aim is to model diffusion trajectories of innovation and technology and to study the dynamic gap to achieve low carbon sustainable pathways. The paper obtains policy insights that allow countries reduce its emissions. The role of trade is also discussed in this context to reach emissions reductions established by international agreements.

In this paper we propose to analyze the different results obtained in the symmetric table when applying a shock in supply and use tables (SUTs) depending on the chosen model. To this end, we particularize the analysis to the case study of the Spanish input-output framework, using the supply and use tables published by the National Statistics Institute (NSI) of Spain.
We study, as a first simulation, an increase in the implementation of electricity self-production, which can be understood as the new electricity generated by the initially non-energy industries, which supposes an important change in the production technology and which is a measure in line of the decarbonization process of the economies. To this end, we plan different assumptions and simulations, such as the case in which the new electricity is being generated with the technology of the electricity industry or with the technology of the initially non-electricity sector.
There are also alternative simulations discussed, such as changing the way of production of other products than electricity, or the case of changing the product mix of other industries.
We proceed as follows. We construct the symmetric input-output table using models A, B, C, and D from Eurostat. Then, we apply our simulations modifying the structure of the supply and use tables to include our technological changes. Then, we construct the symmetric input-output tables from each of the options.
With this, we analyze the impacts of those changes using different options of combining the SUTs, which implies different changes in the economic structure. To analyze the different impacts obtained in the symmetric table we use several input-output indicators. We try to see which of the models muffles the changes more with these different simulations, with the objective of highlighting the importance of using one model or other one if we do not want to lose technological change along the time when constructing the symmetric input-output table. Results differ when applying models A, B, C, and D, having different implications for the accurate representation of the reality of the sectors, the technological change, and the policies applied to them.

Methanisation is a process for producing renewable energy, which has recently gained interest as a contribution to a territorial strategy for the deployment of the circular economy. The projects, which are collective in nature, bring together multiple actors or local stakeholders from a wide variety of backgrounds. The article proposes to analyse the territorial governance of this type of project by studying the relations of synergy and cooperation between stakeholders in the case study of the Syndicat Mixte du Point Fort (SMPF) of Cavigny (France). The results of the analysis of interaction and coordination networks show that local stakeholders develop dense relational networks that vary throughout the project. This high density is indicative of the importance of group cohesion in interactions, which is necessary to create a framework of trust and consultation that favours the success of territorial renewable energy projects. The measure of centrality of the interacting actors shows that the project leader (SMPF) plays the role of assembler and facilitator of the interaction networks, and thus facilitates the sharing of flows, knowledge and collective learning.
