2. Accelerating emission reduction in Israel : carbon pricing vs. policy standards

abstract

The implementation of a carbon pricing policy to comply with GHG emission targets faces opposition in small economies. An integrated modeling exercise was carried out for Israel to assess the cost-effectiveness of GHG emission reduction options. Alternative policies in terms of carbon pricing and policy standards are evaluated. The results show that modest carbon pricing is effective. It achieves a 67% reduction in emissions, by 2050 relative to the reference year 2015, while having only a minor impact on economic growth. Policy standards currently proposed by the government will only reach a 40% emissions reduction in the same timeframe. Clean energy standards not coupled with carbon pricing may hinder efficiency but have a lesser impact on income distribution.

3. A renewable energy-centred research agenda for planning and financing Nexus development objectives in rural sub-Saharan Africa

abstract

In rural sub-Saharan Africa - the global poverty hotspot - the vast majority of cropland is rainfed only, resulting in reduced and unstable yields. Smallholder farmers account for 80% of agricultural production but they have limited access to relevant services to support both commercial operations and their livelihoods: more than two-thirds of rural dwellers have no access to electricity (crucial for crop irrigation, processing, and storage) and about 40% have no access to clean water. Previous research has analysed integrated technological and resource management approaches to tackle these overlapping development gaps. To finance and implement such transformations in resource-constrained settings, it is now crucial to understand the business and investment implications, also considering the strong regional population growth and the increasing frequency and intensity of climate extremes. Here, we lay out a research agenda that promotes the integration of multi-scale modelling excellence along the climate-water-renewable energy-agriculture-development Nexus and the creation of robust business models for private companies that can sustainably support private smallholder farmers of SSAin their effort to eradicate poverty and inequality. The proposed agenda is a cornerstone of the EC-H2020 project LEAP-RE RE4AFAGRI ("Renewable Energy for African Agriculture: Integrating Modelling Excellence and Robust Business Models"). In proposing the agenda, we highlight the importance of integrating energy access into the Nexus framework from both research and investment perspectives.

4. The next frontier for climate change science : insights from the authors of the IPCC 6th assessment report on knowledge gaps and priorities for research

abstract

As climate change impacts intensify globally in both frequency and magnitude, and with scientific consensus on what is yet to come if the world fails to act, the imperative to step up our collective response has never been more pressing. By providing the knowledge necessary to formulate effective mitigation and adaptation strategies, climate science serves as a critical enabler of climate action and a vital input to evidence-based policymaking. Bridging the knowledge gaps in climate change research is crucial for guiding the transition towards a low-carbon climate resilient future, for fostering consensus and alliances, for empowering global cooperation and for mobilising stakeholders across the society. This report draws attention to where additional research is required to effectively and adequately address climate change, aiming to inform future calls under the EU Horizon Europe R&I Programme and beyond.

5. Enabling or Hampering? Climate Risk and the Role of Finance in the Low-Carbon Transition

abstract

While there is a broad understanding that the financial system can play a major enabling role in achieving the low-carbon transition, it is not well understood under which specific conditions such an orderly transition scenario when finance works as an enabler could occur. Even more importantly, it has not been clarified under which conditions the financial system could instead hamper the low-carbon transition. Overlooking the possible (even temporary) hampering role of the financial system in the low-carbon transition can lead to a large underestimation of climate transition risk. The set of scenarios that financial supervisors recommended to investors to analyse climate transition risk include scenarios labelled as ‘disorderly transition’. Nevertheless, there are important limitations in interpreting such scenarios in terms of a disorderly transition. In particular, since in the climate economic models currently used by financial supervisors, finance plays no role, it is not possible to investigate the conditions for the financial system to act as an enabler or as a barrier for the low-carbon transition. To shed light on this issue, here we analyse how the economic trajectories of these climate economics models are reshaped depending on the timing and the extent by which financial actors assess climate risk

6. Accounting for finance is key for climate mitigation pathways

abstract

The financial system, the ecosystem of investors (e.g., banks, investment funds, insurance), markets, and instruments, is often considered to play an enabling role in climate mitigation pathways to a low-carbon transition. But it can also have a hampering role, e.g., if investors’ perceptions of low risk from a missed transition and low opportunities from a transition fail to trigger a reallocation of capital into low-carbon investments. This increases the chance of the transition not occur-ring within the time window required to stabilize the climate or occurring in a disorderly fashion. But investors, who can influence the realization of climate mitigation pathways, themselves rely upon estimates of climate mitigation pathways from process-based Integrated Assessment Models (IAMs). And IAMs do not model the financial system nor investors’ decisions, thus the feedback loop between the financial system and mitigation pathways is not taken into account by the IAMs nor by the finance community. This limitation to our understanding of the dynamics and the feasibility of the low-carbon transition weakens the ability of IAMs to inform policy and investment decisions. We propose a framework to capture the interdependence between investors’ perception of future climate risk, depending on the credibility of climate policies, and the allocation of in-vestments in the economy

8. Regional low-emission pathways from global models

abstract

Governments worldwide have agreed that international climate policy should aim to limit the increase of global mean temperature to less than 2oC with respect to pre-industrial levels. The purpose of this paper is to analyse the emission reductions and related energy system changes in various countries in pathways consistent with the 2oC target. We synthesize and provide an overview of the national and regional information contained in different scenarios from various global models published over the last few years, as well as yet unpublished scenarios submitted by modelling teams participating in the MILES project (Modelling and Informing Low-Emission Strategies). We find that emissions in the mitigation scenarios are significantly reduced in all regions compared to the baseline without climate policies. The regional cumulative CO2 emissions show on average a 76% reduction between the baseline and 450 scenario. The 450 scenarios show a reduction of primary energy demand in all countries of roughly 30-40% compared to the baseline. In the baseline scenario, the contribution of low-carbon energy technology remains around 15%, i.e. similar as today. In the mitigation scenario, these numbers are scaled up rapidly towards 2050. Looking at air quality, sulphur dioxide and black carbon emissions are strongly reduced as a co-benefit of greenhouse gas emission reductions, in both developing and developed countries. However, black carbon emissions increase in countries that strongly rely on bioenergy to reach mitigation targets. Concerning energy security, energy importing countries generally experience a decrease in net-energy imports in mitigation scenarios compared to the baseline development, while energy exporters experience a loss of energy export revenues.
