In the last three years, green hydrogen has been gaining significant momentum. Hydrogen will become a key component of decarbonisation strategies, enabling low-carbon energy storage and transportation. Producing cost-competitive hydrogen is difficult because of insufficient technology and manufacturing readiness levels, lack of scale and lack of political support. Economies of scale for hydrogen production could be achieved by introducing hydrogen in global industries which are major CO2 emitters. One of those is steel-making, accounting for roughly 7% of global CO2 emissions.
Il G20 in Italia, tutte le notizie e gli aggiornamenti
Il G20, ovvero “Gruppo dei 20”, è il principale forum di cooperazione economica e finanziaria a livello globale. Si tiene ogni anno, e riunisce le principali economie del mondo, ovvero Canada, Francia, Germania, Giappone, Regno Unito e Stati Uniti (cioè i paesi del G7), i paesi del gruppo “BRICS” – Brasile, Russia, India, Cina e Sudafrica – e anche Arabia Saudita, Australia, Argentina, Corea del Sud, Indonesia, Messico e Turchia. A questi si aggiunge anche l’Unione Europea. Si tratta di un gruppo di paesi che costituiscono l’80% del PIL globale, nonché il 60% della popolazione del pianeta. Quest’anno la presidenza è dell’Italia.
Resource extraction and consumption is projected to double by 2060. However, today only 8.6% of raw materials extracted are put back into circulation, which worsens pressure on ecosystems, intensifies pollution and waste issues, and accelerates climate change. The transition from a linear to a circular economy opens a pathway for a green, more sustainable and resource-conscious future.
Forests and the ocean are vital for climate, biological diversity, and human communities, but they are degraded and their ecosystem services are seriously impaired, mainly because financial, economic and governance structures are misconfigured. We propose that G20 help strengthen the REDD+ climate instrument for forests and extend it to Blue Carbon1 from coastal and marine ecosystems. Scaled up to cover the Earth’s two largest, most diverse and most productive ecosystems, these two approaches can deliver significant economic and climate benefits.
The COVID-19 pandemic has led many countries to initiate unprecedented economic recovery packages. G20 policy makers tackling the health crisis, which is far from over, have also been encouraged to prioritise strategies which help to mitigate another looming crisis of climate change. Among the policy interventions that support climate change mitigation, promoting investments in labour intensive green infrastructure, establishing a private financing catalysing facility, and designing ambitious carbon pricing schemes are found to boost economic recovery in the short and medium-term.
Catalysing the G20’s competitive advantage on global climate action, this policy brief proposes: 1. To swiftly act to fill the existing vacuum on coordination in the global governance architecture imperative to align the legal and policy regimes on climate and trade. Coordination is the G20’s remit and imperative for systemic global scale action, as demonstrated by the COVID-19 pandemic.
The G20 should control climate change by mobilizing nature-based solutions to:
Sulle tre grandi tematiche - pandemia, ambiente, e ripresa economica - serve maggiore coordinamento, per evitare gli errori passati. Con una prospettiva che sia davvero globale.
Agricultural production is both strongly affected by climate change and a major contributor to climate change, with agriculture and land-use change accounting for about one fifth of total global greenhouse gas emissions – more than for transport or industrial uses. Agricultural production benefits from substantial government support, costing at least US$ 640 billion per year worldwide. Past and current support have an impact on greenhouse gas emissions by influencing the composition and location of output, and production practices.
This brief elaborates on the development of sustainable agriculture in smart cities, addressing the challenges related to increasing demand for protein-rich food due to intense urbanisation. It considers development of the appropriate technologies and optimised infrastructure required for the massive uptake of smart urban farming and simultaneously enabling circular economy mechanisms for recycling waste into value assets.
Digital technologies are indispensable for achieving sustainable development goals and reducing carbon emissions in many sectors. Yet, computer systems themselves have an immense energy requirement for their countless devices, data centres, applications and global networks. With COVID-19, the shift to digital in living, learning and earning has raised the spectre of digital harms and brought us closer to the time when digitalisation will become an increasing social and climate hazard.
We are living in a dynamic and changing world, one that requires youth and young people to be critically informed and prepared to address a range of global sustainability challenges. This policy brief calls for the establishment of a G20 Commission on Youth Education for Sustainable Development to identify the support needed to accelerate the integration of ICT-enabled education for sustainable development, and to provide guidance on the (re-) formation of national policies and strategies to increase youth voice and agency vis-à-vis sustainability at local and national levels.
The COVID-19 pandemic has changed the relationship between the market economy, state and society in almost every country worldwide. While the economy paused and literally shut down in many countries during the first wave of the pandemic, the state and civil society have gained new significance in protecting people from the ravages of the coronavirus. This shift has affected the public’s perception of the role of markets, government and society in response to the worldwide shock.
