Green Premium in the Tokyo Office Rent Market

More than 10 years have passed since studies on green buildings gained attention in the academic and industrial literature. Many studies report the economic value of green buildings, mainly in the U.S. and European markets. An empirical clarification of the dynamics of green premiums has significant implications for future urban sustainability. This study constructed a dataset of Tokyo office rents from 2009 to 2019. We estimated the green office rental premium using a hedonic approach. Our results show that, on average, an office property with a green label gains a premium of approximately 6.5% on contract rents. The Tokyo office market is heterogeneous, and endogeneity is an issue when identifying the green premium. We addressed the endogeneity issue with propensity score clustering. As a result of our estimation, the premium was approximately +5.4% for medium sized-old buildings and +2.6% for large-sized new buildings.

Understanding the Barriers to Offshore Green-Hydrogen Production

The stage is set to begin making “green” hydrogen from the world’s abundant supply of seawater. But whether this niche-within-a-niche can stand on its own and become a competitive energy source remains uncertain. Today, only about 1% of man-made hydrogen is considered to be green, and not a single atom of it is produced offshore. In the offshore concept, the green label will be earned by splitting the hydrogen out of desalinated seawater with electrolyzers that run on renewable wind energy. This represents an opportunity for oil and gas companies to not just lower their carbon footprints, but to leverage billions of dollars’ worth of existing offshore infrastructure. Their platforms can host the electrolyzers. Their pipelines can transfer the product to shore. They may even be able to power their offshore facilities using the hydrogen produced at sea. Offshore producers should also have no problem finding a market. PriceWaterhouseCoopers said in a report from last year that green-hydrogen exports could be worth $300 billion annually by 2050, supporting some 400,000 jobs globally. However, the first set of offshore pilots are still in planning mode. It will take a few more years to assess the results once they start up. That means we may not know if offshore hydrogen is commercially viable until decade’s end. Some of the biggest barriers that must be overcome were highlighted by a panel of leading hydrogen experts at the recent Offshore Technology Conference (OTC) in Houston. Green Hydrogen in the Red “The major hurdle is still the cost,” explained René Peters. “The cost of hydrogen production with electrolysis is still extremely high compared to gray- and blue-hydrogen production.” Peters is the business director at the Dutch technology group TNO which is one of a dozen partners trying to launch PosHYdon, the pilot for offshore hydrogen production. Startup is expected by early 2023 on a normally unmanned oil and gas platform operated by independent oil and gas company Neptune Energy. Peters’ comments on cost were not relegated to the offshore aspect since all green hydrogen is made onshore today. In terms of tipping point for profitability, these are the relevant benchmarks.

Estimating the Willingness to Pay for Eco-Labeled Products of Formosan Pangolin (Manis pentadactyla pentadactyla) Conservation

Pangolins are currently the most smuggled mammals in the world. Meanwhile, Taiwan has demonstrated the world’s first case of the use of artificial feeding to raise pangolins to adulthood. The government has also begun to cooperate with farmers in pangolin-spotted areas. Agricultural products can earn the green label once they have passed the evaluation. The challenge is that very few farms have obtained the pangolin-friendly label so far. Our hypothesis is that farmers lack the knowledge that consumers would pay additional money for products that are labeled pangolin-friendly compared to regular ones. Thus, farmers have an insufficient incentive to apply for this label. This research aims to fill this gap by providing people with the necessary knowledge. Contingent valuation with the single-bounded dichotomous choice format was used, which involved investigating 417 valid observations. We found the following: (1) customers are willing to pay about 8.06 USD for pangolin-friendly rice (an increase of 397% in relation to the mean price of rice); (2) customers are willing to pay for about 11.46 USD for pangolin-friendly tea (an increase of 179% in relation to the mean price of tea); and (3) customers are willing to pay about 25.81 USD for pangolin-friendly coffee (an increase of 509% in relation to the mean price of coffee). Our findings give farmers more incentive to conduct eco-friendly production. Consequently, the quality of agricultural products as well as the habitats of endangered pangolins improve. Thus, consumers’ health, the environment, and the future of pangolin conservation can benefit in this attempt to achieve sustainability.

Sensory Characterization of Iberian Dry-Cured Loins by Using Check-All-That-Apply (CATA) Analysis and Multiple-Intake Temporal Dominance of Sensations (TDS)

The aim of the present work was to sensorially characterize different commercial categories of Iberian dry-cured loins (varying genetic and feeding background) using a novel dynamic sensory technique, and to explore consumers preferences applying a rapid method. The samples (green label—GL, Cebo de Campo Ibérico; red label—RL, Bellota 50% Ibérico; and black label—BL, Bellota 100%) were analyzed by (i) Check-all-that-apply (CATA) with the evaluation of an ‘Ideal’ dry-cured loin and the overall liking, and by (ii) multiple-intake Temporal Dominance of Sensations (TDS). The CATA results indicated that the sensory characteristics of RL samples were closer to those of the ‘Ideal’ loin. Furthermore, juiciness, marbling, cured flavor, chewiness, persistence, and brightness were selected as ‘must-have’ attributes. Juiciness cured flavor and red color were considered as drivers of liking. TDS results showed that flavor attributes presented the highest dominance rates, with saltiness being the most dominant attribute along BL sample evaluation, and with cured and paprika flavor for GL and RL samples. These sensory technique results displayed the ability to sensorily characterize dry-cured loins, providing different, complementary, and valuable information.

Woody biomass for energy use will face rising scrutiny

Significance There is an obvious tension between promoting forests to capture carbon and burning wood for energy. Increased demand risks unsustainable indirect changes of land use. However, modern forestry practices suggest woody biomass can be used sustainably, if forest eco-systems are well managed. Impacts Although it continues to carry a green label, debate over its sustainability may damage financial flows into the biomass sector. The sector focus on secondary and tertiary wood sources, as well as wood industry by-products, will increase. Woody biomass use for heat and power will make up a key part of renewable energy generation, particularly in heavily forested countries.

Bacterial nanocellulose and fibroin: natural products to produce a structure membranes

ABSTRACT Fibroin (FB) and bacterial nanocellulose (BC) are natural products, being used in biomedicine, electronics, food industries and other areas. Both show biocompatibility, able to be used for many different purposes. The blending of fibroin and bacterial nanocellulose was design to produce a biocompatible material to be applied with a medical device. For this reason, the objective of this work was to evaluate the structure properties of the blending of BC and FB. Thus, FB was extracted from Bombyx mori and BC was produced by fermentation process utilizing Gluconacetobacter xylinus. The membranes composed of BC-FB were produced by immersion contact for 24 hours, at 25°C, in 100rpm; without crosslinking agent. After the production the membrane samples were dried and characterized by Fourier transform infrared spectroscopy (FTIR spectroscopy), mechanical proprieties, swelling efficiency, scanning electron microscopy (SEM) and computerized microtomography (µCt). Results indicate that the hydrogen-bonded porous membranes obtained displayed anisiotropic, closed and interconnected porous morphology. The morphometric characteristics, which resemble a honeycomb and consist of a long structure with high connectivity and high total porosity, amplify the areas of BC-FB blend applications, with potential utilization with optoelectronic devices, in areas ranging from environmental to tissue engineering. Furthermore, the production by immersion contact will allow the upscale process and the development of green label material.

Case studies.

This section illustrates Value Chain Thinking (VCT) in practice, using a combination of our development project experiences and Australia Awards Africa case studies that we have mentored. It provides case studies on which VCT has been put into practice: These examples cover: aquaculture on Lake Victoria, Kenya; Pakistani mangoes; Ghanaian pineapples; livestock value chains covering Madagascan goats, Ugandan rabbits, Ghanaian guinea fowl, Nigerian catfish and Kenyan indigenous chicken; and vegetable value chains in Ethiopia, Tanzania, Malawi and Mozambique. Then the researchers offer two novel applications of VCT: (1) to improve children's nutrition in Madagascar, Cameroon and Zambia, as well as value chain members' livelihoods; and (2) to design and operate the Ghana Green Label scheme for food certification covering both safety and environmental assurances.

Toxic Gaslighting: On the Ins and Outs of Pollution

Outdoor images predominate in cultural conceptions of “air pollution,” whilst indoor air quality (IAQ) is typically tenfold more contaminated. Recent nonprofit research revealed that “green label” carpet contains up to 44 hazardous substances. How and why do school administrators not know this? When people speak colloquially about “toxic” schools, they typically refer to social environments whose power dynamics are manipulated by difficult people (bullies, narcissists, gaslighters, etc.). In this article, I borrow the cultural concept of gaslighting to query how and why the literal off-gassing of banal objects like carpet have escaped scientific inquiry. In dialogue with recent innovative air studies in California that blur the boundaries of in/outdoor pollution, this auto-ethnographic paper chronicles a carpet controversy at “Beacon” Elementary, a bilingual school in the Central Valley. Even as outdoor smoke from California wildfires in 2017 pushed PM2.5 levels past red into unprecedented magenta alerts, children were sickened inside school classrooms after new carpets were laid in 2017. By “outing” internal school board communication through repeated public records requests, Beacon mothers discovered how a chemical risk manager on the board manipulated confusion about patterns of pollution to dismiss the mothers’ citizen science of the chemical abuse of their children. When pollution occurs out-of-sight (in locked classrooms) or affects groups rarely studied in exposure (minors), institutions can easily deploy gaslighting techniques of doubt, denial, and disavowal of the chemical abuse of children. Given the slow (Nixon 2011), delayed, incremental, and “gaslighted” nature of modern chemical violence, even those harmed by chronic pollution may misrecognize the symptoms; those that do recognize the symptoms may be perceived or portrayed as delusional in stories worthy of Hollywood noir.

Carpet Bombings

Outdoor images predominate in our cultural conceptions of “air pollution” even though indoor air quality (IAQ) is typically tenfold more contaminated. New modeling of LA smog in Science suggests that source emissions from indoor and personal care products contribute more to that city’s infamous poor air quality than vehicular combustion. In similar paradox, even as outdoor smoke from California wildfires in 2017 pushed PM2.5 levels past red into unprecedented magenta alerts, children were sickened inside school classrooms after new carpets were laid. This auto-ethnographic paper chronicles our ongoing struggle to remove those carpets from “Beacon” Elementary, a bilingual Mexican-American school in California's Central Valley that has suffered decades of racialized neglect of its facilities. Forging through the uncertain epidemiology of environmental illness, “Beacon” mothers began documenting their children’s ailments after the new carpet installation, but the school district dismissed the mothers' citizen science. The Superintendent continued to vouch for the carpet’s safety based on the industry’s voluntary “Green Label.” A historical section of this article therefore recounts how and why the carpet industry invented this label in the aftermath of a scandal in which new carpets sickened a fifth of the EPA workforce at their headquarters in Washington, DC between 1987 and 1988. Thirty years later, once again, three California environmental regulatory agencies are scrutinizing the carpet industry for hazardous ingredients.
