Timing of Mitigation and Technology Availability in Achieving a Low-Carbon World

This paper analyzes the economic and investment implications of a series of climate mitigation scenarios, characterized by different levels of ambition for long-term stabilization goals and transitional pathways. Results indicate that although milder climate objectives can be achieved at moderate costs, stringent stabilization paths, compatible with the 2°C target, might require significant economic resources. Innovation and technology are shown to be able to mitigate, but not structurally alter, this trade-off. Technologies that allow capturing CO₂ from the atmosphere are shown to be important for expanding the feasibility space of stringent climate policies, though only if deployed at a scale which would represent a tremendous challenge. In general, the analysis indicates that the timing of mitigation is an important factor of cost containment, with early action being desirable. It also elaborates on the set of mitigation strategies and policies that would be required to achieve climate protection at maximum efficiency.     

Data Envelopment Analysis of different climate policy scenarios

Recent developments in the political, scientific and economic debate on climate change suggest that it is of critical importance to develop new approaches able to compare policy scenarios for their environmental effectiveness, their distributive effects, their enforceability, their costs and many other dimensions. This paper discusses a quantitative methodology to assess the relative performance of different climate policy scenarios when accounting for their long-term economic, social and environmental impacts. The proposed procedure is based on Data Envelopment Analysis, here employed in evaluating the relative efficiency of eleven global climate policy scenarios. The methodology provides a promising comparison framework; it can be seen as a way of setting some basic guidelines to frame further debates and negotiations and can be flexibly adopted and modified by decision makers to obtain relevant information for policy design. Three major findings emerge from this analysis: (i) stringent climate policies can outperform less ambitious proposals if all sustainability dimensions are taken into account; (ii) a carefully chosen burden-sharing rule is able to bring together climate stabilisation and equity considerations; and (iii) the most inefficient strategy results from the failure to negotiate a post-2012 global climate agreement.     

Environmental Policy and the International Diffusion of Cleaner Energy Technologies

Technology transfer is an important channel of technological change and sustainable development for countries with less innovative ability than technological leaders. This paper studies whether domestic environmental policies affect the inward technology transfer of cleaner innovation from abroad. We focus specifically on the power sector, for its important role in the decarbonization process, by looking at zero-carbon (renewable) and carbon-saving (efficient fossil) technologies for energy production. Using data on cross-country patent applications, we provide evidence that environmental policy contributes to attracting foreign cleaner technology options to OECD markets but not to non-OECD markets. We show that this is due to the nature of the implemented policy instruments. Market-based approaches positively impact technology transfer to both OECD and non-OECD economies, while non-market based approaches have at best only a weak effect in OECD countries. Domestic environmental policies may provide too weak a signal for foreign innovators in countries off the technological frontier. This calls for a strengthening of policy incentives for technology transfer in light of pressing climate change objectives.     

A Good Opening: The Key to Make the Most of Unilateral Climate Action

In this paper we argue that when a subgroup of countries cooperate on emission reduction, the optimal response of non-signatory countries reflects the interaction between three potentially opposing factors, the incentive to free-ride on the environmental benefits of cooperation, the incentive to expand energy consumption, and the incentive to adopt the cleaner technologies introduced by the coalition. Using an Integrated Assessment Model with a game-theoretic structure we find that the equilibrium abatement of the coalition composed by OECD countries would be moderate, in line with the Pledges subscribed in Copenhagen, but increasing. The mitigation strategy would consist of investments in energy R&D and deployment of cleaner technologies with high learning potentials. International knowledge and technology externalities would facilitate the diffusion of cleaner technologies in non-signatory countries, offsetting the free-riding incentive and reducing their emissions. If the OECD group curbs emissions beyond the optimal equilibrium level, reaching reduction rates between 40 and 45 % below 2005 levels in 2050, the benefits of technology externalities would no longer compensate the effect of lower fossil fuel prices. Our results suggest that a moderate unilateral climate policy could induce a virtuous behaviour in non-signatory countries and that policies promoting the international transfer of technologies and knowledge could represent an effective complement to mitigation targets.     

The Value of Flexibility: Preservation, Remediation, or Development for Ginostra?

We are concerned with land allocation andinvestment decisions when dealing withpartially degraded areas that might be (1)remediated and returned to a more natural state;or (2) irreversibly developed. This type ofproblem seems particularly relevant in Europewhere the issue of wilderness conservation isof less concern than the remediation oflandscapes which have been altered by previouseconomic activities. Traditional expectedpresent value analysis will fail to capture thevalue of investments that might be undertakensequentially or when certain investments areirreversible. We show how to determine, withina discrete-time, stochastic model, the optimaladaptive development strategy and how tocalculate the option value of flexibility. Thetheoretical model is then applied to Ginostra,a town on Stromboli, an island off the southerncoast of Italy.     

Board Independence and Internal Committees in the BRICs

To be successful in global markets, companies from the emerging countries need the approval of foreign investors and other stakeholders. In this regard, Brazil, Russia, India, and China （BRIC） have progressively strengthened their corporate governance rules to help their companies overcome the competitors from the old industrialized countries. Directors＇ non-executive qualification, independence, and professional expertise represent basic requirements for effective corporate governance, so they should be carefully considered to guarantee a proper board composition and an adequate establishment of internal committees in listed companies. The paper intends to compare the legislative and regulatory frameworks adopted by the four countries; then it aims at answering to the following research questions by means of an empirical investigation： Have BRIC companies appointed non-executive and independent board members？ What do BRIC companies do in order to assure an effective participation of non-executive and independent board members to corporate governance activities？ Have BRIC companies established internal committees？ The research examines the appointment of non-executive directors and independent directors to the boards of 100 BRIC leading firms, as well as their involvement in internal committees focused on matters requiring motivated and impartial opinions. Although the laws and recommendations seem to favor a general convergence of corporate governance principles among the four BRIC and towards the international best practices, some differences and peculiarities emerge from a firm-level perspective. Indeed, the Indian and the Chinese companies analyzed appear more inclined than the Brazilian and the Russian ones to reassure their international stakeholders about board independence and effective committees.
