Research supports the negative effect of Green Electricity tariffs on corporate energy efficiency efforts.

Posted by on Oct 13, 2020 in Uncategorized | 0 comments

Those of you who have followed my previous articles on LinkedIn will know that I have a particular bugbear about Green Electricity tariffs.

I have three fundamental objections to these tariffs:

1.      The tariffs are based on a lie. The renewable electricity has been produced as a result of the subsidy paid for by all electricity consumers not from any contribution made by the organisations or individuals falsely claiming it for themselves.

2.      The use of these tariffs to report lower emissions leads to double-counting of emissions reductions. This is because the renewable generation is usually part of the mandatory target for utility companies and so form part of the UK-wide ‘location-based’ grid average CO2 conversion factors, but the same renewable electricity is used by  the “green” tariffs consumers in their own ‘market-based’ calculations to claim zero emissions. As a result, the overall emissions recorded are lower than they actually are.

3.      Most worryingly, is the possibility that that the Green Electricity tariffs disincentivise important efforts to reduce electricity use. After all, why invest additional time and money in the difficult work of energy efficiency if the emissions are already zero?

The latter concern has, until now, merely been a suspicion on my part, based on my own interactions with decision-makers in many organisations. Mindful that I could not find any research on this topic, I was delighted when my son, Connor Enright decided to look into this subject for his Natural Sciences Master’s thesis at the University of East Anglia – with the full support of his School and input of his thesis supervisors, of course.

My assessment of the Oxford Offsetting Principles.

Amongst all the possible responses to climate change few topics are as hotly debated and controversial as offsetting. So it was with interest that I read the recently released “Oxford Principles for Net Zero Aligned Carbon Offsetting”.

This is a brief (12-page) document produced by a number of collaborators from a range of disciplines and schools in the University of Oxford. Its objective is to redefine best practice for offsetting as we aim for net-zero emissions and beyond.

The question in my mind is will I recommend to my clients that they adopt these principles?

While I do have some practical concerns about these principles, as described below, I would strongly recommend my fellow climate change and sustainability practitioners look at these and contribute to the debate about what offsetting is and should achieve.

UKGBC Energy Performance Targets for Offices: a case study in why over-ambition is not SMART.

Posted by on Feb 28, 2020 in Articles, Blog, Uncategorized | 0 comments

In this long format article I will explore why a knee-jerk response to the climate emergency can lead to well intentioned but counterproductive consequences. I have heard it said that we are living in a time where political reality is approximating scientific reality – at last policymakers are beginning to grasp what science has been saying for many years. This article explores another critical dimension, which I will call engineering reality, where I believe that much of the hard work and tough choices around climate change will be focused. The broader themes in this article are absolutely central to our success or failure and are offered not as a criticism of one specific response, but as a broader lesson to all those who can influence our responses to climate change.

The climate emergency is real and requires a rapid and effective response. Our success in delivering fast decarbonisation of our economy depends on myriad decisions taken in every sector based on our knowledge of the technologies, skills and finance available. These decisions are intricate and complex, not helped by a large number of uncertainties about the future, inconsistent data and conflicting visions of how to achieve Net Zero emissions.The climate emergency is real and requires a rapid and effective response.

Those of us who have been in the business of sustainability for a long time[1] crave a John F. Kennedy moment: “we will put a man on the moon by the end of the decade”. We fancy the notion of a mobilisation of all resources available to limit climate change, to adopt a state of war where combating climate change become the overwhelming priority in everything we do. We can’t wait to see the many barriers we have faced in the past come tumbling down.

The profound flaws with Payback

Posted by on Mar 17, 2019 in Uncategorized | 0 comments

Simple payback, often referred to just as payback, describes the length of time needed for the savings generated by a resource efficiency project to return the initial investment made. It is calculated using the formula:

Thus, an investment of US$1,000 that yields regular annual savings of US$500 has a payback of two years. The annualized saving could be determined by a number of uneven cash flows, e.g. US$250 in year 1 and US$750 in year 2; here, the payback period is determined by adding up successive savings in the cash flow until they match the investment. If we are interested in the payback in months, then we would multiply the annual payback by 12.

Fear of flying*

Posted by on Mar 14, 2019 in Uncategorized | 0 comments

I am writing this post from Goa, on the West coast of India. I flew here from Manchester, in the premium economy section of a Tui Boeing 787 Dreamliner. 

According to the ICAO carbon calculator [1] the aircraft will have burned 54 tonnes of fuel on each leg of the journey, which equates to 654kg of CO2 per passenger (2x the standard economy emissions due to the “premium” cabin seating). The plane was full, so I think the calculations are reasonable and, while I could argue that “premium economy” is not really twice the space or mass of standard economy, I don’t quibble with the figures.

Capability and Motivation – why you need both to achieve change.

Posted by on Feb 28, 2019 in Articles, My Book | 0 comments

For change to happen, people and teams need two things: the capability to carry out the required action and the desire to do so. Capability reflects many aspects such as knowledge and skills, as well as resources like time and money. Motivation can be intrinsic due to beliefs and attitudes or extrinsic due to instructions, incentives, penalties or social norms.

Understanding Capability and Motivation can help us develop the right strategy for change.

Capability and motivation are related. An easy-to-implement behaviour change (i.e. one for where the existing capability to act is high) will need much less motivation than a challenging behaviour change (i.e. one which requires lots of resources, time, effort, risk-taking, knowledge, etc).

Understanding the interrelationship between capability and motivation can dramatically increase the chance of success of our change programme.

Are small actions counter-productive?

Posted by on Feb 25, 2019 in Blog, Books | 0 comments

I started my book on energy and resource efficiency (available free as a pdf) with a traditional saying:

“How do you eat an elephant? Why, one bite at a time, of course”.

In the section on availability barriers to resource efficiency, I argued that we can drive a successful efficiency programme by getting a lot of people to regularly dedicate a little time rather than by getting a few people to commit a lot of time. Clearly, we need to start with where people are at and it is often unrealistic to ask someone to make a large change in their behaviour from the outset. Indeed, asking for too much or holding back for “perfection” are the root causes of many programme failures I have observed with my own eyes. So starting small is a reasonable strategy.

Is that true, though? Some argue that if all that we request in terms of change is a minor action, then this will result in – surprise, surprise – a small result! Folks like Donella Meadows, Bob Doppelt and many others have reasoned eloquently that no less than a fundamental change to our underlying systems will deliver the scale of change needed to address the magnitude of the problems we face. Similarly, Cambridge Professor David MacKay, in his fantastic book Sustainable Energy — without the hot air  asserts:

Lighting Tool Updated

Posted by on Feb 21, 2019 in Uncategorized | 0 comments

The popular Lighting tool has been updated to version 1.3. Previous versions may fail to return Latitude and Longitude when a user enters a location name, displaying instead “REQUEST_DENIED”.

The reason for this is that Google Maps has started charging for geolocation requests used in our “mashup”, and so SustainSuccess has now opened an account with Google to cover the costs of these requests.

To protect our budget, we have limited the number requests per day, so if you get this message in version 1.3, please try again the following day or enter a Latitude and Longitude manually.

To upload the new version, please follow the link, right.

Is the EU Emissions Trading Scheme responsible for the collapse of flybmi?

Posted by on Feb 17, 2019 in Articles, News | 0 comments

 

I would probably  have taken little interest in yesterday’s announcement that a relatively small regional airline, flybmi, has ceased trading, if it was not for the fact they were placing the blame, in part, on the EU Emissions Trading Scheme (ETS). According to the statement on the airline’s website [1]:

The airline has faced several difficulties, including recent spikes in fuel and carbon costs, the latter arising from the EU’s recent decision to exclude UK airlines from full participation in the Emissions Trading Scheme.

So, I wanted to find out if this was really the case.

First of all, the background. You may recall from my earlier post that the EU is facing a real challenge for its flagship ETS as a result of BREXIT. The problem is that allowances in the scheme can be traded freely between member states of the EU but if the UK leaves the scheme ahead of the current Phase (running to 2020), there is a very real risk that the now redundant UK allowances, would flood the market and so render the ETS ineffective at capping carbon emissions.

The UK’s Green Building Council is consulting on what is meant by “Net Zero Carbon”. We need to make sure that the definition is effective.

Posted by on Feb 14, 2019 in Uncategorized | 0 comments

 

Hopefully, the definition will be a rigorous tool to help building developers and operators to achieve the maximum affordable onsite improvements in the building’s emissions. Once these onsite improvements are achieved, the definition will further set out how the residual emissions can be genuinely reduced through credible, independently verified offsite activities, leading to “net zero” or event “net negative”.

Alternatively, the definition could be a cheap and nasty fig leaf facilitating another decade of flat-line performance on emissions in the property sector.

In order to avoid the latter it is important that folks respond to the consultation on the meaning on “net zero” in buildings, which closes on the 1st March. Looking at the consultation, I would say that the outcome is finely balanced – so please do make the effort to understand the issues and make your voice heard in the consultation. Filling in a response will take around ½ hour – what better use of your time?
