Debated in Parliament on 13 Sep 2021.
Debate resumed.
Mr Deputy Speaker, we must continue our work of reducing carbon dioxide and greenhouse gas emissions and sustain the reduction for decades to come. Under most emissions scenarios that are being modelled today, the global surface temperature will most certainly continue to increase until the middle of this century. In fact, the target of 1.5 degrees celsius and two degrees celsius temperature rise will most certainly be exceeded unless we do more, much more.
In the coming years and decades, we will experience changes in our climate system with increase in heatwaves, droughts and more intense storms. Here in Singapore, we will most probably experience heavier precipitation. Throughout the world, we will continue to see the massive loss of sea ice, snow cover and permafrost.
Many of such changes were caused by past greenhouse gas emissions and are irreversible for centuries and up to a millennia. These changes and impact are most prevalent in our ice sheets and global sea levels. Today's emissions and the emissions of the future, will further contribute to these irreversible changes: ocean warming, ocean acidification, deoxygenation, melting glaciers and ice sheets, just to name a few.
Recently, I visited Pulau Ubin – lovely island. Coincidentally, I was there at high tide. The waves were crashing onto the sides of the rocks near the jetty. It would probably take less than another metre of sea level rise before the seawater would flood the coastal roads. With current estimates, the sea level will rise by two to three metres if the temperature rise is limited to 1.5 degrees celsius and two to six metres if limited to two degrees celsius. At two degrees celsius and a six-metre corresponding rise in sea level, not much of Pulau Ubin would be left above water.
We must do more to better control and regulate our greenhouse emissions, be bold and quicken the pace. We are in a race against time. Mr Deputy Speaker, I support the Bill.
Mr Deputy Speaker, Sir, I support all the measures to reduce the emissions of hydrofluorocarbon (HFC) refrigerants from refrigeration and air-conditioning (RAC) equipment. These measures, coupled with effective enforcement, will definitely go a long way to help mitigate climate change.
However, I have some concerns about the amendment to ensure that construction sites remain quiet on Sundays and public holidays. The Ministry intends to achieve this by requiring errant contractors to install electronic video surveillance systems.
Due to the pandemic, many construction projects have been delayed. Now, with our economy gradually adjusting to a new norm, contractors are trying to catch up on the works in progress. I would like to ask: how do we balance the need to expedite these construction projects, while ensuring disamenities like noise pollution are kept to acceptable levels?
With the shortage of workers and the urgency to rush jobs, more machinery might be used. Then, what comes immediately to mind is safety. So again, another delicate balance between productivity and safety. Would the Ministry be stepping up safety briefings and inspections? Can the same CCTVs be used to enhance safety at the worksites? The purpose is not so much to penalise and punish contractors, but rather to help spot any safety concerns early. This will allow contractors to be alerted and take remedial action to ensure safety.
Next, I have a query about the integrity of the video recordings. I had encountered cases in my community where NEA received complaints from residents about noise but when they went down to check the construction sites, the noise level was considered acceptable. As technology is so advanced, how can we be sure that the recordings that both the residents and NEA encountered are similar?
The layman does not know what is an acceptable noise level and what is not. I would like to suggest that information on how to discern when maximum levels have been breached be set up at our worksites. These would be very helpful, so that residents are informed and can tell if rules have been flouted. Sir, in Mandarin.
(In Mandarin): [Please refer to Vernacular Speech.] I have some questions regarding the amendment to ensure that construction sites remain quiet on Sundays and public holidays. Due to the pandemic, many construction projects had been delayed. Now, many contractors are trying to expedite their works. How are we going to balance their need to expedite construction, while at the same time, ensure that the noise pollution is maintained at an acceptable level? In addition, in this situation of rushing for work to be done, how do we ensure safety at worksites?
The Ministry will require errant contractors to install video surveillance systems. How can we ensure that the recordings will not be tampered with? Most residents do not know what the acceptable noise level is, as set by the Ministry. I would like to suggest that worksites set up information notices about noise pollution. This will be helpful to let our residents know under what conditions the regulations are violated.
(In English): Sir, I support the Bill.
Mr Deputy Speaker, Sir, I support the measures to reduce the use and emissions of hydrofluorocarbon (HFC) refrigerants. However, in view of the current difficulties faced by many companies due to the untamed COVID-19 pandemic, would the Ministry consider reviewing the appropriate time to introduce these measures? My concern is that some of these measures will increase costs for SMEs.
For example, low Global Warming Potential (GWP) commercial water-cooled chillers cost more upfront. We can also expect the higher costs to impact end-users. What measures does the Government have to help manage the impact? How will the Ministry ensure that our cold chain needs will not be adversely affected by the increased costs?
Another area contributing to higher costs is the certification of technicians handling refrigerants. Only certified technicians will be permitted to supervise or service chillers. Mandatory collection and treatment of spent refrigerants will also entail additional costs. Who will bear the fees?
Hence, I appeal to the Ministry to consider delaying the implementation of some of the measures during these challenging times, so as to give our SMEs more breathing room and time to adjust to the new regulations. Mr Deputy Speaker, Sir, in Mandarin.
(In Mandarin): [Please refer to Vernacular Speech.] In order to ensure that construction sites remain quiet on Sundays and public holidays, the authorities will require errant contractors to install video surveillance systems. I would like to know what is the impact of this new requirement on the construction sector. I am concerned that such unnecessary costs will be levied on these SMEs and many of them are already suffering now.
In addition, are the relevant departments considering using other measures to ensure that construction companies abide by the no-work regulations and better manage construction noise? Currently, what measures have the Ministry’s agencies implemented to reduce construction noise in residential areas? Can we use mobile phones to report errant contractors? Notwithstanding all my concerns and enquiries, I support the Bill.
Mr Deputy Speaker, Sir, it is timely to rein in the emission of pollutants such as gases and noise. This is pertinent in densely populated Singapore, where there are many concurrent ongoing construction activities, with some at close proximity to residential areas.
This is especially pronounced in Yio Chu Kang. There are construction works going on for the North-South Corridor and the new Thomson-East Coast Line. New BTO flats and private estate projects are being built in Yio Chu Kang. There are also existing upgrading works, for instance, at Mayflower Primary School. While I am happy to see such developments, many are taking place simultaneously. The effects of accumulated noise and dust can be vexing to residents. Furthermore, many projects have been extended due to COVID-19. I have received many feedback on noise pollution at my Meet-the-People Sessions (MPS).
In my speech, I will focus on managing noise from construction sites.
First, Mr Deputy Speaker, Sir, we should have better feedback management systems for residents to provide feedback on such matters. I support the new requirement for construction sites who have contravened the no-work rule on Sundays and public holidays to install electronic video surveillance systems.
Over the years, authorities have increasingly leveraged on technology to monitor noise levels at construction sites. However, feedback from residents in the vicinity remains important, as they are personally impacted and may have practical concerns. As such, there should be dedicated feedback channels for residents to relay their concerns to the contractor. There should also be clear escalation protocols to NEA as the regulator, should problems remain unresolved, despite the initial feedback to the contractor. The relevant authorities should ensure that clear service standards are in place as to when replies must be provided.
It should also be mandatory to provide advance notice to residents living within a 150-metre radius from the construction site. This could be in the form of information on display boards, as well as flyers distributed to nearby blocks. NEA should also consider using Municipal Services Office (MSO)'s OneService app to push out notifications to residents living near construction sites. This will give ample time to residents, whether it is to facilitate alternative arrangements, or to find ways to mitigate the noise.
Contact details for the contractor and the relevant NEA feedback channels must also be clear and visible to residents. On my rounds, I noticed that the display of contact details was not uniform for all sites. Some constructions sites display their contact details and project information on a large board. However, for certain works, especially smaller-scale ones, the information is not always immediately visible. Some residents can therefore be surprised to see a barricaded project site appear, out of the blue. They do not know what it was for and do not know who to ask. I hope the Ministry can standardise the format and requirements for displaying relevant information and communication channels.
Second, Mr Deputy Speaker, Sir, there needs to be more public education with regards to no-work days. Work is allowed on weekends for projects that meet certain criteria. Nevertheless, the ground reality is that this is not publicly known. As such, members of public would lodge a complaint when they see construction works during the weekends, despite the works being permitted by NEA. With the COVID-19-related delays, I expect that more projects would seek permission to work on weekends. Therefore, there needs to be more awareness and better understanding of the regulations. This is to avoid wasting residents' time and Government's resources to manage redundant feedback.
Third, Mr Deputy Speaker, Sir, we need to ensure that video surveillance support remains sustainable and effective. Can NEA provide a rough estimate on the cost of installation and maintenance of video surveillance equipment? One of the common reasons worksites contravene no-work days is because they are racing against a deadline and budget. So, my concern is if quality video surveillance equipment is costly to install and maintain, they may have some challenges setting it up within the stipulated timeline. Some errant contractors may even try to cut corners.
Moreover, as technology becomes increasingly sophisticated, we are observing a rise in digital capabilities to tamper with video equipment to create false content. How will NEA ensure that the equipment would not be tampered with, to present a fallacious impression?
Fourth, Mr Deputy Speaker, we need greater clarity on the type of construction projects covered under the new amendments. Besides construction sites, I would like to seek clarification as to whether it also covers other projects that generate noise and other possible disruptions. Are small scale infrastructure developments in the housing estates like the building of covered linkways by the Town Council, piping works by PUB, or road works by LTA covered as well? What about home renovations for HDB and condominium apartments, as well as additions and alterations for houses in landed estates?
The legislation ought to have a clearer definition on the projects it applies to. This could be determined by the project scale or some other measurable criteria, such as the amount of noise pollution emitted or the number of residents that would be impacted. Once the types of project sites are identified, we should also incrementally move towards having mandatory sound and dust-proof barriers for all these work sites.
Mr Deputy Speaker, Sir, my last point is on imposing heavier penalties on construction companies that breach the no-work rule. For many Singaporeans, Sundays and public holidays are the only days in a week when they can take a break and recharge. Loud noise over prolonged periods triggers anxiety and stress. This is exacerbated by work-from-home arrangements during this pandemic period. Also, noise monitoring should not be limited to volume alone, but also frequency. Having mediated for community disputes among neighbours previously, some arising from construction noise, I can attest first-hand to the impact of unwanted noise on one’s mental well-being.
Currently, there is a proposed penalty of a composition sum of $5,000 for construction sites that break the no-work rule for the first time. Subsequent offences lead to a Court summons with a maximum fine of $40,000. If we are to meaningfully address noise pollution as a threat to public health and not just as a mere annoyance, would these penalties be too light? As a more effective deterrent, violation of the no-work regulation ought to bear heavier consequences on the contractor’s ability to succeed at the next tender bid. We should also require such offences to be highlighted, when they next bid for projects.
In conclusion, Mr Deputy Speaker, Sir, noise pollution is a real issue on the ground. I did a check in the Hansard. Issues relating to construction noise have been consistently brought up in Parliament on several occasions over the past 10 years, despite ongoing reviews to manage disamenities. Instead of having discrete and piecemeal recommendations, we need a multifaceted and holistic approach to tackle noise pollution. As mentioned in my speech, these include better feedback management, promoting greater public awareness of no-work days and having stronger guidelines on surveillance systems. We should also have greater clarity on the type of construction projects covered under the new amendments and have more enforcement bite.
I believe that these suggestions working together as a system, will make a difference on the ground. I support the Bill.
Minister of State Desmond Tan.
Mr Deputy Speaker, first, I thank the Members for their support of the Bill. The thoughtful comments and suggestions that were raised reflect our collective commitment to climate action and to provide a quality living environment for Singaporeans.
I will first address Members’ questions on the measures to reduce HFC emissions from refrigeration and air-conditioning, or RAC, equipment.
HFC accounts for a sizeable share of Singapore’s greenhouse gas emissions. As Mr Louis Ng pointed out, there was a 30% increase in HFC emissions from 2014 to 2016 and this underscores the urgent need for action, which Mr Shawn Huang as well as Mr Louis Chua have also emphasised. The measures introduced today will deliver deep cuts in HFC emissions and bring us closer to our climate goals.
Mr Don Wee suggested delaying the measures in view of the current economic conditions caused by the pandemic. I wish to clarify that the requirement to use low-GWP refrigerants applies only to new regulated equipment that is supplied from 1 October 2022. Companies can continue to use their existing equipment until the end of life for those equipment.
While low-GWP chillers may cost a little more, they are typically more energy and carbon efficient and offer net cost savings over their lifecycle. So, investing in them not only protects the climate, but also protects companies from being locked into the higher operating costs of less efficient chillers. For example, CapitaLand expects to reap lifecycle cost savings of $280,000 from its low-GWP chiller deployed in Funan.
Companies that are replacing their chillers in the immediate future can tap on the grant introduced in October 2020 to incentivise the early switch to low-GWP chillers, before the supply restriction comes into force in October 2022. So far, 10 projects have been approved or are under consideration. These projects are expected to collectively abate HFC emissions equivalent to 60 kilotonnes of carbon dioxide, comparable to taking around 18,000 cars off the road.
One grant recipient is Kaer Pte Ltd, an energy services company which provides "Cooling as a Service". With grant support, Kaer is replacing chillers at an industrial facility with climate-friendly ones that not only use low-GWP refrigerant, but will also improve the system’s energy efficiency by 35%.
As Mr Louis Ng has highlighted, proper refrigerant handling practices are important to minimise HFC emissions during servicing and maintenance of RAC equipment.
We have worked closely with Temasek Polytechnic and industry partners to develop a training and certification programme for chiller technicians. This two-day programme has been designed to be practical and relevant to the industry and will cover the processes for handling and recovering refrigerants from chillers. Technicians will be re-certified every three years to keep up with advancements in technology.
Mr Louis Ng and Mr Gan Thiam Poh asked whether the course could be held in other languages aside from English. The course is designed to meet the needs of the technicians. It will be conducted in simple spoken English. Temasek Polytechnic has ample experience in conducting other similar technical courses and trainers will tailor their delivery to suit the language competency of the technicians. Trainers will also give practical demonstrations and conduct hands-on practice to enhance understanding. To be certified, technicians have to pass an open-book test comprising multiple choice questions and a simple practical assessment. In fact, during my visit to Temasek Polytechnic, I noticed that the course will be conducted, hands-on, by technicians for the technicians themselves. So, it will be done in a simple manner, using languages that the technicians can understand.
Mr Desmond Choo, Mr Louis Ng and Mr Gan Thiam Poh have asked if there would be financial support for these technicians. Singaporeans and PRs will be eligible for up to 90% subsidies under SkillsFuture SG and the balance of $85 can be paid for using their SkillsFuture credits.
We agree with Mr Desmond Choo that companies need time to develop internal processes and train their technicians. For this reason, we announced the requirements early in March last year. We have since been engaging the industry closely to develop these measures and will continue to do so to ensure a smooth transition.
I am also pleased to inform Mr Desmond Choo that the register for registered suppliers and registered regulated goods will be made accessible online. This was a question that was asked by Mr Louis Chua as well.
Mr Desmond Choo also proposed stricter penalties for the offence of falsifying information or data under the new section 40X. The penalty of a fine not exceeding $5,000 or imprisonment for a term not exceeding three months, or both, is aligned to similar offences under the Energy Conservation Act. From our experience, this serves as sufficient deterrence and we will review the penalty level should data falsification become an issue of concern, going forward.
Mr Don Wee asked whether requiring spent refrigerants to be recovered and treated will add to business cost. This is unlikely, as most of the spent refrigerants can be treated for reuse and have commercial value. Today, even in the absence of regulation, there is already a market for them and facilities to treat spent refrigerants are already available.
Mr Louis Ng also asked about our plans to address HFC emissions beyond the current measures. We are studying the potential for other types of RAC equipment, such as commercial and industrial refrigeration units, to switch to low-GWP refrigerants. We will need to assess the feasibility of available technologies, balancing considerations such as fire safety, toxicity, energy efficiency and the cost of suitable substitutes. In response to Mr Louis Chua, we will consult and work closely with industries and businesses, and give sufficient lead time before implementing any measures.
I assure Mr Don Wee that we will carefully consider the cost impact on our cold chain needs when assessing any future measures on commercial and industrial refrigeration units. The measures introduced today have no impact on cold chain needs, as climate-friendly household refrigerators do not cost more.
Prof Hoon Hian Teck asked whether it would be better to price HFC emissions rather than regulate these. While pricing remains an option, there are merits in adopting regulations to reduce HFC emissions. Most jurisdictions also take this approach. HFC emissions arise mainly from ownership rather than the intensity of use of RAC equipment and are locked in by technology choices. Given technical complexity and the need to balance multiple considerations in the choice of refrigerants as highlighted earlier, it is difficult for end-users to make informed choices or to influence upstream supplier decisions. Regulation offers much greater outcome certainty in abating HFC emissions. In commercial chillers, for example, regulation will effect a switch to a new generation of refrigerants with GWP close to zero, bringing HFC emissions to negligible levels when the entire stock of chillers turns over.
Even if taxation were to be introduced, these considerations mean that regulations may still be needed. We would have to consider the cost effectiveness of the taxation regime, given the highly distributed sources of emissions. While the tax can be levied upstream on importers, this has to be coupled with the system of downstream rebates for spent refrigerants that are recovered. This could potentially result in higher administrative costs.
Mr Louis Chua also asked about the abatement potential and plans for the Kigali Amendment. The HFC mitigation measures introduced today are expected to reduce HFC emissions from the regulated equipment by around half by the year 2030. With regard to the Kigali Amendment, my Ministry has initiated a review and is consulting key stakeholders. We will update when ready.
I will now address Members’ questions on construction noise and the requirement for contractors, who have violated the no-work rule, to install, maintain and operate video surveillance at their construction sites.
First, let me address questions on the implementation of the requirement for video surveillance.
Mr Yip Hon Weng asked about the types of construction projects that are covered. The current regulations state that all construction sites located less than 150 metres from any hospital, home for the aged sick or residential building must comply with the no-work rule on Sundays and public holidays. The Bill does not change the no-work rule regulation or requirement. Under this Bill, the Director-General may now impose the requirement for video surveillance on any construction site that contravenes the no-work rule. So, the site has to contravene the rule first. The requirement applies to all public and private sector construction projects, regardless of the size, if they violate the no-work rule.
It is important to ensure the integrity and proper functioning of the video surveillance systems, as Mr Gan Thiam Poh, Mr Yip Hon Weng and Ms Joan Pereira have pointed out. NEA will carry out scheduled and surprise site inspections to ensure that the video surveillance systems are in good working condition and not tampered with.
The new section 28A empowers the Director-General to specify requirements for the video surveillance system, including ensuring that the system's security is not compromised. For example, contractors should implement robust digital identification (ID) and password controls and restrict access to the physical components of the system. The person required to install, to operate and to maintain the video surveillance system under the new section 28A must also take all reasonable steps to ensure that no person tampers with or does anything to compromise the proper functioning of the system or any image, sound or video recorded by the system.
Mr Don Wee asked whether phone video footages can be used to substantiate complaints on no-work rule violations in place of video surveillance. While phone video footages can be used as evidence for prosecution, they might not capture sufficient information on the construction activities being carried out to conclude that there was indeed an offence. Such footages received from the public might also not be timely enough to address ongoing construction noise infringements.
On the other hand, the installed video surveillance will allow NEA to remotely monitor construction worksites and deter repeat violations. It enhances NEA's efficiency and responsiveness, removing the need for officers to carry out repeated inspections to address recurring public feedback.
I assure Mr Don Wee and Mr Yip Hon Weng that we are mindful of the impact of the measures on the construction industry, which is facing challenging times. The requirement will only be imposed on the very small group of construction sites that have breached the no-work rule. This is around 150 out of the 5,800 construction sites a year, or about 3% of all active sites. It will not affect the vast majority of construction sites that comply with the no-work rule.
The cost of installing video surveillance stands at less than 1% of total construction project cost on average. One set of closed-circuit television (CCTV), for example, can cost about $5,000. Depending on the project size, a construction site that has violated the no-work rule may be required to install up to four CCTVs.
Mr Yip Hon Weng highlighted other complementary measures to strengthen compliance to the no-work rule, such as introducing higher penalties. The vast majority of construction sites comply with the no-work rule. NEA will monitor the effectiveness of these measures in this Bill to address the remaining small group of non-compliant contractors and consider further measures, if needed.
Let me now address points raised by Members on managing construction noise in residential areas beyond the no-work rule.
We have to strike a careful balance between maintaining a conducive living environment and also allowing construction work to be completed within a reasonable duration and cost. We need to maintain a steady supply of public housing, continue expanding our public transport network and provide amenities such as hospitals and schools.
As Mr Yip Hon Weng pointed out, many projects have been significantly delayed due to the COVID-19 pandemic. This impacts end users such as families waiting to move into their Build-To-Order (BTO) flats.
Project delays not only affect the construction industry and end users, they also prolong the disamenities experienced by neighbouring residents.
Ms Joan Pereira also spoke about balancing the need to expedite projects that have been delayed while keeping disamenities to acceptable levels. This, in fact, is the balance that we need to strike.
Mr Louis Ng asked for an update on the review of construction noise limits. Given the significant impact of the COVID-19 pandemic on the construction industry, this is not the time to tighten construction noise limits which will affect the whole industry. We recognise that the construction sector faces serious manpower and supply shortages during these extraordinary times.
Nevertheless, I assure Mr Louis Ng that NEA will monitor the situation and continue to work with stakeholders to review construction noise limits, including the limits for construction work on Saturdays, taking into account the World Health Organization's guidelines and our local context.
Mr Yip Hon Weng gave useful suggestions to improve feedback management for residents, including having dedicated feedback channels, clear escalation protocols, standardising format for displaying communication channels and providing advance notice to residents. Many of these measures are already in place and we will see how to improve and enhance them.
For example, as part of construction works that require a BCA permit, the contractor must erect a project signboard of at least 1.8 metres in width and one metre in height before work can commence. The project signboard displays information of the project parties and their contact numbers as well as the hotline numbers of MOM, NEA and BCA. Residents can also submit their feedback through the NEA website and the myENV and OneService mobile applications.
Upon receiving feedback, NEA officers will investigate whether the construction site has generated noise levels exceeding the noise limits or violated the no-work rule and then, they take enforcement actions accordingly.
NEA has also been advising contractors to engage the nearby residents early to develop plans to minimise the impact of construction work on residents' daily lives. Contractors have also been encouraged to implement additional noise mitigation measures where possible, such as noise barriers for noisy works like hacking and drilling.
We acknowledge Mr Yip Hon Weng and Ms Joan Pereira's suggestions on improving the public's awareness of the rules on construction noise.
Information on construction noise limits, permissible work hours and the no-work rule is published on NEA's website. Members of the public can reach out to NEA through various communication channels to find out if a particular construction site is permitted to carry out quieter works on Sunday and public holidays or if noise limits have been breached.
NEA will explore raising public awareness on the no-work rule via social media channels.
On Mr Gan Thiam Poh's suggestion to improve the noise-insulating properties of HDB flats, HDB will continue to explore practical noise mitigation measures for the comfort and well-being of residents. Given our high-density environment and with HDB flats being designed for natural ventilation, some noise will inevitably make its way into flats through our open windows and doors.
We will continue to work with stakeholders to better manage construction noise in order to maintain a conducive living environment while allowing projects to keep pace with providing infrastructure and amenities for our residents.
Mr Deputy Speaker, the amendments in the Bill help lay the foundations to achieve our climate ambitions. The early switch to low-GWP equipment and proper management of HFC refrigerants will ensure that the cooling needs and comfort of Singaporeans will not be compromised as we transit to a low-carbon future.
Imposing electronic video surveillance on construction sites which have violated the no-work rule is an important step and addition to our existing enforcement measures. We hope this requirement will improve compliance and help NEA to manage public feedback more effectively. Mr Deputy Speaker, I beg to move.
