Transportation control measures are often implemented for their environmental benefits, but there is a need to quantify what benefits actually occur. Telecommuting has the potential to reduce the number of daily trips and miles traveled with personal vehicles and, consequently, the overall emissions resulting from vehicle activity. This search studies the emissions impacts of telecommuting for the participants of the Puget Sound Telecommuting Demonstration Project (PSTDP). The California Air Resources Board's emissions models, EMFAC7F and BURDEN7F, are used to estimate the emissions on telecommuting days and non-telecommuting days, based on travel diaries completed by program participants. This study, among the first of its kind, represents the most sophisticated application of emissions models to travel diary data.Analysis of the travel diary data and the emissions model output supports the hypothesis that telecommuting has beneficial transportation and air quality impacts. The most important results are that telecommuting decreases the number of daily trips (by 30%), the vehicle-miles traveled (VMT) (by 63%), and the number of cold starts (by 44%), especially those taking place in early morning. These reductions are shown to have a large effect on daily emissions, with a 50% to 60% decrease in pollutants generated by a telecommuter's personal vehicle use on a telecommuting day. These net savings are almost entirely due to the elimination of commute trips, as non-commute trips increased by 0.33 trips per person-day (9% of the total trips), and the non-commute VMT increased by 2.2 miles. Overall reduc-IMPLICATIONS Telecommuting is one of many Transportation Demand Management (TDM) strategies being considered by policy makers to reduce congestion levels and improve air quality. As one of the first studies to directly measure the impacts of telecommuting on vehicle emissions levels, this research contributes to a new body of data on the air quality impacts of telecommuting. The findings support the hypothesis that telecommuting benefits both air quality and congestion. The methodology presented may be applied to other TDMs to analyze the comparative impacts of each strategy. This information will help policy makers identify the most effective congestion reduction and air quality improvement approaches.tions in travel and emissions of this magnitude are observed because the telecommuters in this sample are long-distance commuters, with commutes twice as long as the regional average. However, even as telecommuting adoption moves into the mainstream, its net impacts are still expected to be beneficial-a reduction in VMT and in emissions.It is important to note that when the level of telecommuting is considered (that is, the percentage of work days that employees actually telecommute), the weekly savings are a much smaller proportion of total weekday travel. Also, these findings represent average per-capita reductions; the aggregate (or overall, regionwide) impacts are determined by scaling these reductions by...

Background: Evidence shows that online solicitation facilitates sex workers’ ability to mitigate the risk of workplace violence. However, little is known about how end-demand sex work criminalization and the regulation of online sex work sites shape men and non-binary sex workers’ ability to maintain their own safety while soliciting services online. Methods: We conducted 21 semi-structured interviews with men and non-binary sex workers in British Columbia between 2020–2021 and examined their ability to enact safety strategies online in the context of end-demand criminalization. Analysis drew on a structural determinants of health framework. Results: Most participants emphasized that sex work is not inherently dangerous and described how soliciting services online facilitated their ability to enact personal safety strategies and remain in control of client interactions. However, participants also described how end-demand criminalization, sex work stigma, and restrictive website policies compromise their ability to solicit services online and to enact safety strategies. Conclusions: Alongside calls to decriminalize sex work, these findings emphasize the need to normalize sex work as a form of labour, promote access to online solicitation among men and non-binary sex workers, and develop standards for online sex work platforms in partnership with sex workers that prioritize sex worker safety.

Background Lower-risk substance use guidelines (LRSUGs) are an evidence-based harm reduction strategy used to provide information to people who use drugs so they can reduce harms associated with substance use. Objectives This study aimed to identify LRSUGs accessible to youth and to characterize the recommendations within these guidelines. The overall goal is to identify gaps in current LRSUGs and to inform researchers and policymakers of the kinds of health information youth can access. Methods We conducted a digital assessment using the Google search engine to identify LRSUGs that could be identified by youth when searching for official sources of information related to commonly used substances, including cannabis, caffeine, alcohol, hallucinogens, prescription opioids, nicotine, and/or prescription stimulants. LRSUGs were coded and data were extracted from them to identify gaps. Results One hundred thirty LRSUGs were identified; most focused on alcohol (n = 40, 31%), cannabis (n = 30, 23%), and caffeine (n = 21, 16%). LRSUGs provided recommendations about dosing (n = 108, 83%), frequency of use (n = 72, 55%), and when to use (n = 86, 66%). Most LRSUGs were published by health (n = 51, 39%) and third-sector organizations (n = 41, 32%), followed by provincial/state (n = 18, 14%), government (n = 14, 11%), municipal (n = 4, 3%), and academic (n = 2, 2%) sources. Only 16% (n = 21) of LRSUGs were youth-specific and one-quarter (n = 32, 25%) of LRSUGs provided gender-specific recommendations. Most guidelines featured information on short (n = 76, 58%) and long-term (n = 69, 53%) negative effectives and positive effects of substances (n = 56, 43%). Less than half (n = 50, 38%) of LRSUGs cited evidence in support of the information they provided. Conclusions We identified several areas in the current LRSUGs for youth that need to be addressed. Among the gaps are a lack of LRSUGs developed specifically for youth, a lack of youth engagement in developing harm reduction strategies centered around them, and a lack of evidence-based LRSUGs. Youth-oriented, evidence-based LRSUGs are needed to better support youth who use substances and help them manage the negative effects of substance use.
