Life Cycle Assessment for Amazon Product

Life Cycle Assessment for Amazon Product

We have recently been commissioned to undertake a Life Cycle Assessment for a product being sold on Amazon Marketplace. Despite offering Life Cycle Assessment Services for over 10 years this is the first time we have produced a Life Cycle Assessment for Amazon Product.

Climate Pledge Friendly

If you have been shopping for drones or vegetables on Amazon recently you may have noticed the Climate Pledge Friendly tick box. If you select this, then only Climate Pledge Friendly items will show up in your search.

In order to back up this green claim, it is required that you submit a life cycle assessment (whole life or size reduction) and have it assessed by a third party.

How it Works

We can arrange all aspects of this process for you. We will carry out the required data collections, and or calculations to prove a size reduction, or carbon footprint for your product. We will then provide this information to a 3rd party certification body. Who will also offer you various choices in terms of  carbon offsets.

Once this has been completed we will provide information to you so it can be submitted to Amazon, and you product be included under Climate Pledge Friendly category.

We point out at this point that we are no endorsed in any way by Amazon. But we have been carrying out Life Cycle Assessments for over 10 years. Contact Us to find out more.

Phosphates Mitigation Reports

2021 was quite a busy year for Southwest Environmental Limited, we had a fairly typical work load from our long term client base, however we have seen a lot of new work from new clients relating to phosphate assessments, and nutrient neutrality.

We have undertaken reports mainly in the Southwest, however we have also undertaken some reporting for sites in the south east, in the vicinity of Stodmarsh.

Despite having a few reports passed off, and dealing with 100’s of emails with regards to extra details, from planners, natural england, and ecologists the majority of applications mired by the Phosphate Issue remain in limbo.

It would appear there is no one cable or willing to make a decision to pass off the reports.

Some of the older reports date back to November 2020, and as you might expect that is a long time to wait for news on a planning application.

Our reports are now however quite thorough in terms of their content. We have iron out early wrinkles experience in early days of 2021, and had many discussions with consultees and planners, adjust and refining our reporting process each time to meet content requirements.

We have advised on on-site schemes, such as reed beds, or on-site woodland (sometimes a combination of both), and we have a method for reduce reed bed sizes using a special filtration method.

Some sites are not able to implement on-site schemes owing to perhaps lack of space or proximity to mains sewer. In these instances we have specified off-site mitigation schemes such as woodland. Off-site reed bed schemes are a very complicated proposition.

If you would like to discuss your project and any associated phosphate, nitrate or nutrient issues associated with it. Then please do contact us.

Sustainability & Energy Statement – Bristol

Sustainability & Energy Statement – Bristol 

Acting on instructions from a private client Southwest Environmental have prepared a Sustainability statement in support of a planning application in Bristol. The site lies in the Windmill Hill Area which is not overly far from Bristol Temple Meads Railway Station.

The proposed development sees the conversion of a a terraced house into two flats. The sustainability statement was produced and covers the carbon reduction (40%) as required by Bristol City Policies, and also looked in to Cycle Parking and Refuse Storage.

Cycle parking is an important provision as it means that future occupants may use their bike, rather than their car. This keeps them fit and also reduces traffic on the roads. As of February 2018 transport is the biggest single emitter of CO2 in the UK, even larger than the energy generation sector which is recently “over took”.

Sheffield Hoops

Cycle parking is normally provided via the use of the sheffield hoop. These allow for an easy rest, and an anchor point when parking a cycle. However owing to the site layout, there was no room for sheffield hoops to the front of the property.

The 20% carbon reduction was met via a combination of energy saving measures and solar PV power generation.

Sunlight Daylight Assessment

Sunlight & Daylight Assessment – Epsom

Acting on instruction from a repeat client in the Epsom area, Southwest Environmental Limited are undertaking a Sunlight and Daylight Assessment for a prestige development of 2 no. 6 bedroom houses, which occupy the plot of a single smaller dwelling.

The scheme makes very good use of the space available, but unfortunately in the first instance the height of the buildings was a little too great, as it caused loss of daylight to a neighbouring kitchen window that was beyond the loss allowable under BRE 209.

Recommendations were made that involved altering the pitch of the roof, and allowing for a flat roof area, where it would not impact of the character of the property. This reduced overshadowing to the point where, the scheme became acceptable.

The reduction in height did not result in any loss of usable internal space, although it did result in some loss of loft space, which may have been suitable for conversion in the future.

Sustainability Statement – Lyppiatt Road, Bristol

Sustainability Statement – Lyppiatt Road, Bristol

Acting Upon instructions from a property developer in Bristol SWEL have assembled a sustainability statement for a multi the residential development win commercial grounds floor use. The development incorporates large areas of south facing glazing and as such specific concerns were raised by Bristol City council regarding overheating potential mitigating measures such as

Overhanging shading were stipulated as possible future upgrades these future upgrades were included within plans with space left for them to be added as a future date when and if some overheating becomes a problem.

Bristol City council have recently started to require detailed energy Modeling at the planning stage SWELconducted a whole building energy model for the development which allows for the presentation of building energy demand and the subsequent : savings achieved through efficiency and renewable energy measures.

Sustainability Statement – Lyppiatt Rd, Bristol BS5 9HP, UK

Acting on instruction of a property developer SWEL have produced a Sustainability Statement for a site in   Lyppiatt Rd, Bristol. The site is a mixed use development incorporating residential and commercial spaces.

The project has a highly fragmented roof, and options were explored to perhaps use combined heat and power in order to provide emissions savings in line with BCC Policy BCS 14, which requires that a carbon reduction of 20% is achieved beyond building regulations.

Other Bristol City Council Sustainability Policies include:

BCS13: Climate Change – Requires development to both mitigate and adapt to climate change.

BCS14: Sustainable Energy – Provides criteria for assessing new renewable energy schemes, with a presumption In favor of large‐scale renewable energy installations.

Requires new development to minimise its energy requirements and then incorporate an element of renewable energy to reduce its CO2 emissions by a further 20%. Supports the delivery of a district heating network in Bristol.

BCS15: Sustainable Design and Construction – Requires all developments to engage with issues around sustainable design and construction.

As with London Sustainability Statements, Bristol City Council also require that the energy hierarchy is followed :

  1. Be Lean
  2. Be Clean
  3. Be Green

Sustainability Statement – Nottingham

Sustainability Statement – Nottingham 

Acting on instructions from a repeat client, SWEL are to prepare a sustainability statement for a car show room in Nottingham.

The car show room is a new build, and will incorporate a wealth of sustainability features.  The report submitted complements existing plans and specifications, whilst meeting requires for content set by the local planning authority.

The sustainability report includes modelling of the building envelope using SBEM, and will include renewable obligations set by the LPA.

Energy Statement – Nailsea, North Somerset

Energy Statement – Nailsea, North Somerset

Acting on instructions from a cobstruction company in North Somerset SWEL are to prepare an energy statement for a high specification home to the south of Bristol.

The residential development consists of a large hill side dwelling with terraces and swimming pool. 

The development is to be built to Code for Sustainable Homes Level 3. This would see emissions reductions required and levels of fabric energy efficiency above those specified in the building regulations.

The above axiometric projections were produced by Zebra Architects Worcester.

SWEL have prepared Sustainability and Energy Statements for projects all over the UK. We have experience in Code for Sustainable Homes up to Level 6, and BREEAM Excellent (including refurbishments).

Sustainability Statement – Bristol

Sustainability Statement Bristol

SWEL have recently prepared a sustainability statement for a project in Bristol. The report was wriiten to meet the demands of Bristol City Council, and contained measures to be implemented in order to meet requirements set out in local policy.

As with all our reports, the sustainability statement was written on a quicjk turnaround provided within 10 days of commissioning.

SWEl based our recommendations to suite the clients pre-existing design.

The scheme was a fairly typical residential change of use application.

The sustainability statement was submitted to Bristol City Council well in advance of stipulated deadlines, and the report was well received.

Sunlight & Daylight Assessment – Hackney (N1)

Sunlight & Daylight Assessment – Hackney

SWEl have just sucessfull completed a sunlight & daylight assessment for an unusual retrofit project in Cazenove (Hackney) London.

The project invloves the install of a further two stories on top of an existing building the design is modern and well considered to reduce daylighting impacts, with a tiered design with width decreasing upwards.

The surrounding buildings were subject to considerable overshadowing prior to the development, and as such only minimal reductions in enjoyed light were acceptable.

Sunlight & Daylight reduction post project were within limits set in the relavent guidance, and as such the project with minor alterations was recommended to proceed.
