[en] The French energy system is to change radically and have a 'net zero carbon footprint' in 2050. For the gas industry, this means lower demand and the replacement of natural gas with gases from renewable sources, as prescribed by the nation's low-carbon strategy. To avoid underestimating the optimal volume of renewable gases, this strategy should have taken account of the systemic interactions between forms of energy and the practical constraints on users. Furthermore, several scenarios should have been evoked; the effects of international trade, taken into account; and the analysis, broadened beyond the field of energy (to agriculture, wastes...). This would have shown that assigning more importance to gases from renewable sources (eventually imported) with a faster short-term development than foreseen by the strategy opens a way for reaching carbon neutrality in 2050 that would be less costly and less coercive for users and, too, more robust for coping with the unforeseen.

[en] This contract defines the public service obligations of GRTgaz as a public gas transmission company. These obligations cover: the safety of facilities and people upstream of the end user's connection, the continuity and security of gas supplies according to the regulations in force, the quality and prices of the delivered products and services, the environment protection rules and in particular the implementation of energy conservation measures, the energy efficiency, the valorisation of biogas, the balanced development of the French territory, and the last resort supply of gas to non-domestic customers ensuring a mission of general interest. Beside the continuity and security of gas supplies, the document treats of the following aspects: the emergency situations, the maintenance operations on the network, the transport capacities, the development of the network and the attractiveness of the French gas market, the projects benefiting from European support, the management of congestions, the odorization practices, the promotion of new gas uses (mobility, NGV, biomethane), the quality relations with customers and intervening parties (communication, respect of good practices, quality assurance, smart-grids development), the safety and environmental quality of infrastructures, the R and D involvement in safety, management, environment protection, new gas uses and smart-grids

[en] This publication states twenty five reasons to use natural gas for vehicle (NGV) or natural biogas for vehicle (bio-NGV) as a vector of energy transition. These reasons are related to health and ecological, energetic, or economic and industrial stakes. It outlines that these fuels are a serious alternative to oil-based fuels. Then, various examples are presented to illustrate initiatives of local communities, productions of new vehicles of good or passenger transport, natural gas transport and storage, and the commitment of actors of the gas sector

[en] After an indication of various events organised during the Green gas Tour (meetings and visits of biogas production sites), this publication proposes interviews of various personalities, opinions and reports which illustrate the various dimensions of the development of green gas: agriculture (the choice of agricultural methanisation is a choice of a more sustainable agriculture), the environment (the green gas is an actual ecological asset), territories (it is necessary to promote and support the development of a circular and solidarity-based economy), finance (a new and sustainable economic model is emerging), the energy mix (there is no energy transition without a diversified energy mix), and industry (biogas exhibits a high potential of industrial development).

[en] After the opening and closing speeches of the Minister of Ecology and the intervention of the Prime Minister, a first assessment of the Climate Plan is proposed. This assessment addresses issues related to awareness raising and to adaptation, to sustainable transports, to building and eco-habitat, to industry, to energy, to wastes, to sustainable agriculture and forests, to sustainable air-conditioning, to territorial Climate Plans and to the exemplary State, and to research, international action and prospective after 2010. Then, after a speech of the Minister of Ecology during a Mayor Congress on the Territorial Climate Plan, and a press communique on the Climate Rendezvous, contributions to this rendezvous are provided. For the first day, these contributions propose an assessment of Climate Plan implementation, presentations about the status of scientific knowledge, about climate evolution in France, about stakes and international negotiations to come, about a first assessment of the application of the Climate Plan in terms of emissions and projections. Workshops addressed road transports (clean vehicles and alternatives to road), renewable energy and energy management, territorial climate plans, buildings and energy efficiency (awareness raising, regulation, incentive), actors to develop a climate culture. The second day addressed strategy, stakes and actions for a climate policy. After an opening speech, round tables addressed orientations and actual solutions through the following topics: the factor 4 and new energy technologies, carbon finance and project mechanisms, air transport as a sector for after 2012. Another set of round tables addressed evolutions of our society: adaptation actions in front of consequences of climate change, ways to articulate climate policy and job dynamics
