Does patents on environmental technologies matter for the ecological footprint in the USA? Evidence from the novel Fourier ARDL approach

The outcome of patents on environmental(POET)technologies on the EF in the USA has not been com-prehensively explored.Therefore,to close this breach in the literature,the present study discovers how patents on ecological technologies affect ecological footprint(EF)in the USA while regulatory for GDP and EC using the Fourier-based approaches.The conclusions of the present study reveal that POET are an important predictor of EF in the USA and cause a reduction in ecological deprivation in the long run;as expected,economic growth negatively affects environmental sustainability.The outcomes suggest that it is possible to resolve conflicts between the economy and the environment by using technological inno-vation.The USA government must reconsider its policy focus,particularly on coal energy sourcing and industrial energy,while continuing with heavy investments in its ambitious renewable energy technol-ogy development plan.Moreover,the government should continue to promote investments in environ-mental technologies.

How to promote cooperative innovation in environmentally friendly technology:a case of agricultural biotechnology in China

This study explored the factors influencing cooperative innovation in environmentally friendly agricultural biotechnology in China.First,we constructed an evolutionary game model comprising the factors of net income of cooperative innovation,net income of independent innovation,market constraints,and government subsidies.Using MATLAB simulation,we assigned different values to the aforementioned variables to explore the evolutionary trend of innovators’willingness to cooperate.Results showed that when the values of net income of cooperative innovation,net income of independent innovation,market constraints,and government subsidies exceeded the threshold,innovators’willingness to cooperate was significantly enhanced.Furthermore,the proportion of innovators who cooperated with others gradually increased to 100%;otherwise,it gradually decreased to 0%.Comparing the simulation curve with the real evolution curve of cooperative innovation in agricultural biotechnology in China,we found that the gradual decline in the willingness to cooperate could be due to insufficient subsidies for cooperative innovation,low income from cooperative innovation,weak profitability of innovators,and weak market constraints.

A case for systemic environmental analysis of cultured meat

The environmental implications of cultured meat are profound. An anticipatory life cycle assessment of cultured meat published in 2011 suggested it could have a smaller impact than agricultural meat in all categories except energy consumption. As with most technologies, cultured meat will almost certainly be accompanied by unintended consequences as well as unforeseen costs and benefits that accrue disproportionately to different stakeholders. Uncertainty associated with new engineered products cannot be completely eliminated prior to introduction, but ongoing environmental assessments of the technologies as they advance can serve to reduce unforeseen risks. Given the pace at which tissue engineering is advancing, systemic assessments of the technology will be pivotal in mitigating unintended environmental consequences.

Perspective in development of environmental technology in China

Environmental technology (ET) refers to the processes and techniques for environmental prevention, reduction, recycling, reuse and rehabilitation. Since 1978, China has launched a series of R&D programs in promoting environmental science and technology development. Uneven spatial distribution and sectoral structure give us a profile of the present status of ET in China. Both opportunities and constraints are analyzed for the development of ET, and strategies for its future development are presented in this paper.

Status of CCS Technology in Japan and Brazil： A Comparative Analysis

This article presents a comparative analysis of the technology status of CCS （carbon capture and storage） in Japan and Brazil. Japan＇s GHG （greenhouse Gas） emissions are declining while Brazil＇s are increasing. Among ESTs （environmentally sound technologies） the potential of GHG mitigation of CCS has gained prominence. The research identifies the main activities and positions of the actors involved in CCS technology implementation in Japan and Brazil, and contrasts and compares reasons for the large-scale use of the CCS technologies in the two countries. This analysis is based on a literature review and a field survey done to collect primary data via visits to organizations and experts. This data was enhanced by an analysis of patent deposits in the area of CCS in the two countries in last 20 years. As regards the legal framework for climate change, and for CCS in particular, while responses to the main international decisions can be found in Japan, in Brazil this is not the case. In Japan the public sector has an effective participation together with private sector and civil society. In Brazil CCS activities are conducted by the private sector which is in turn putting pressure on civil society in particular academia. Currently, Japan is focusing on CCS capture technologies, while Brazil is focusing on CCS storage technologies. In summary, the CCS framework is being more efficiently carried out in Japan than in Brazil.

End-of-pipe or process-integrated： evidence from LMDI decomposition of China＇s SO2 emission density reduction

In this study, reduction in sulfur dioxide （SO2） emission is decomposed into three parts： source preven- tion, process control and end-of-pipe treatment, using the Logarithmic Mean Divisia Index method （LMDI）. Source prevention and process control are defined as process- integrated treatment. It is found that from 2001 to 2010 the reduction of SO2 emission density in China was mainly contributed by end-of-pipe treatment. From the 10th Five Year Plan （FYP） period （2001-2005） to the llth FYP period （2006-2010）, the Chinese government has attempted to enhance process-integrated treatment. How- ever, given its initial effort, the effect is limited compared with that of the end-of-pipe treatment. The effectiveness of environmental regulation and technology in the reduction of SO2 density in 30 provinces （municipality/autonomous regions） from 2001 to 2010 is also investigated. This implies that environmental regulation and technology promote process control and end-of-pipe treatment sig- nificantly, but does not influence source prevention. Furthermore, environmental technology will only take effect under the circumstances of stringent environmental regulation. Therefore, to fulfill the whole process treat- ment, environmental regulation should be strengthened and environmental technology upgraded at the same time.

Estimation and comparison of night-time OH levels in the UK urban atmosphere using two different analysis methods

Night-time OH levels have been determined for UK urban surface environments using two methods, the decay and steady state approximation methods. Measurement data from the UK National Environmental Technology Centre archive for four urban sites （Bristol, Harwell, London Eltham and Edinburgh） over the time period of 1996 to 2000 have been used in this study. Three reactive alkenes, namely isoprene, 1,3-butadiene and trans-2-pentene were chosen for the calculation of OH levels by the decay method. Hourly measurements of NO, NO〉 03, CO and 20 VOCs were used to determine night-time OH level using the steady state approximation method. Our results showed that the night-time OH levels were in the range of 1 × 10^3-1× 10^6 molecules/cm3 at these four urbap sites in the UK. The application of a t-test of these analyses indicated that except Bristol, there was no significant difference between the OH levels found from the decay and steady state approximation methods. Night-time levels of the OH radical appeared to peak in summer and spring time tracking the night-time 03 levels which also passed through a maximum at this time.

Exploring the asymmetric impact of economic complexity,FDI,and green technology on carbon emissions:Policy stringency for clean-energy investing countries

All economies are concerned about rising carbon emissions,which contribute to environmental degradation.The current paper formulates a novel framework to scrutinize the impacts of shocks in economic complexity,FDI,environmental technology,and renewable energy on carbon emission in the leading clean energy investment countries,spanning the period from 1995 to 2020.In spite of the constraint for better environmental defence and the realization of the Sustainable Development Goals(SDGs),this paper introduces an empirical approach utilizing the Panel NARDL methodology to investigate the asymmetrical connections between carbon emissions and relevant exogenous factors.Furthermore,we utilize additional techniques,namely AMG and CCEMG,to enhance the robustness of our findings.Our empirical findings reveal that positive shocks in economic complexity,FDI,environmental technology,and renewable energy reduce carbon emissions while negative shocks may result to elevated pollution levels in the long-run.However,adverse shocks in economic complexity and FDI cause increased pollution in the long run.Likewise,the short-run coefficient signs are also similar to the longrun coefficient signs but different in significance level and magnitude.This has paved the way for a well-designed policy for leading clean-energy investment countries should focus on structural change,FDI,technology and renewable energy consumption.
