Why carbon intensity apps are greenwash

There is an app for almost everything. One that recently drew my attention is a carbon intensity app, which at first sight looks really helpful in alerting you to when you can put washing on or charge up batteries while the electricity grid in your area has low carbon emissions.

Renewable energy is not yet stored in sufficient quantity so needs to be used when it’s available. Carbon intensity apps tell you when output from renewable sources of electricity is high and the carbon intensity of the grid is therefore low. 

What’s not to like? Well, the devil is in the detail, as the saying goes. The claims made for these apps are little more than ‘greenwash’, says ACT energy expert Fuad Al-Tawil. Teign Energy Communities (TECs) has produced a detailed explanation of why this is so.

Essentially, the only sure way to lower grid carbon emissions is to increase the renewable energy that feeds into the grid. Point in time readings from a carbon intensity app are not a reliable indicator of surplus low-carbon electricity being available. If demand for electricity from users of the apps increases when intensity is low and there is no renewable surplus, it will just lead to gas being switched on. A gas-fired power station is currently the easiest type of electricity generator to turn on and off at short notice.

There are additional complicating factors due to the way the national grid operates. The financial settlement system for generating, transporting, distributing and consuming electricity is based on price. There is no accounting for carbon emissions. This can lead to renewable generation being turned off and a gas fired power station being turned on to maintain the balance of the grid, so generation and consumption are matched. 

By all means download a carbon intensity app, but don’t assume you will be increasing the use of renewable energy and thereby reducing the carbon intensity of the electricity you buy. 

The only way to help reduce the carbon intensity of the national electricity supply is to encourage the market to build more renewable generation.  You can do this by buying a 100% green tariff from a provider.  Ideally use one of the few providers that buys directly from renewable generators or generates its own supply. TECs names Good Energy and Ecotricity as two such companies. The more people who use such providers, the greater the demand for renewable energy as part of the energy mix of the grid. 

The 100% ‘green’ tariffs offered by other energy companies will not help so much in this regard as they are achieved by a form of offsetting using tradable certificates called REGOs (Renewable Energy Guarantee of Origin). Despite the name, they will not be adding new renewable generation to the grid, simply offsetting against existing renewable generation.  This will not reduce the carbon intensity of the grid. The TECs paper explains this in more detail.

Of course, the most reliable way to reduce emissions from electricity generation is to lower your usage. Use the carbon calculator to work out your carbon footprint then consider what changes you can make to reduce it. Generating your own renewable energy also helps, as does buying from Good Energy or Ecotricity. Sadly, timing your energy consumption to coincide with low carbon intensity periods via an app will not help and could even increase carbon emissions.

Local Plan consultation extended

Teignbridge District Council has extended the consultation period on its Local Plan, moving the closing date from 15th June to 13th July. The change has been made to give people more time to comment, given that face to face meetings are not currently possible.

ACT encourages everyone to submit a response. Feel free to use ACT’s draft response as a reference/template. Please continue to send ACT any comments or suggestions on the draft response as we will not submit it until early July.

The Local Plan and its associated documents can be viewed at: www.teignbridge.gov.uk/localplanreview.

The FAQ section of the documents explains that a Local Plan guides decisions on where and how development takes place. It contains a set of rules, called ‘policies’, which are used to guide decisions on applications for development. The Teignbridge Local Plan is in two parts, with Part 1 guiding decisions on HOW development takes place in Teignbridge, and Part 2 on WHERE developments take place. The consultation is on Part 1.

A burning issue for Dartmoor

I learned a new word recently, swaling, which is the West Country term for controlled burning of moorland. It comes up in the Dartmoor National Park Management Plan 2020-2045, and in ACT’s response to the consultation on the Plan.

Swaling only gets two mentions in the Plan. The first notes that the Moorland Vision for Dartmoor, agreed in 2005, confirmed that swaling, along with grazing, was “essential to delivering the Vision”. The second advises that concerns about swaling being in conflict with climate change objectives were raised when the Management Plan was developed.

One of the Principles in the Plan under the section headed A grazed moorland landscape is to “Ask Government to review the Heather and Grass burning code to provide updated guidance for land managers on management regimes to deliver conservation objectives and respond to the climate emergency.” This needs to take account of the wild fire risk and other means of delivering environmental outcomes, it adds.

ACT in its response says swaling needs to be reduced and better controlled, although this needs to be balanced against the risk of wildfires.

There are many other aspects of the Plan that Act’s response covers but swaling caught my eye because of its novelty value. I looked it up on Google and came across a polemic about the practice by George Monbiot, in which he states that swaling, and grazing (he’s not a big fan of sheep), are causing “an environmental disaster”.

Competing interests will always present challenges, but we must make sure economic interests do not always trump those of wildlife and the environment.

Coronavirus crisis: what comes next?

The coronavirus crisis has demonstrated our vulnerability but has also revealed our care, compassion and community spirit. The links we forge now in our communities will stand us in good stead for the work of pushing forward with climate action.

It is essential to keep the climate emergency on the agenda. Of course, resources and attention are focused on dealing with the human (and economic) cost of the coronavirus pandemic. But the climate and ecological emergencies have not been put on hold. They will still unfold and we have to ensure the need to restart economic activity won’t take precedence over cutting carbon emissions.

The good news is that arguments about not being able to afford to take action on climate change are now exposed as misleading and wrong. Lockdown, and the accompanying damage to financial markets and economies, has revealed that governments and central banks can rustle up the readies when needed.

Writing in the Guardian, historian Adam Tooze examines the extraordinary extent of the interventions by central banks around the world, and in particular by the Federal Reserve, the US central bank. Governments have also had to take action they would never have otherwise contemplated.

The damage caused by pandemics, it turns out, costs even more to fix than was laid out to prevent the 2008 global financial crisis turning into another Great Depression.

The indebtedness of governments after the 2008 crisis was used as an excuse to cut spending . Some commentators are already lining up to say further cuts will have to be made to pay for the new debts incurred in the current crisis. Restarting the economy will be the priority and we will all have to tighten our belts to recover lost ground.

This would be a disastrous response. Instead, the coronavirus crisis offers an opportunity for a rethink, about our priorities, our lifestyles and our future.

We have seen what a world without air pollution looks like, in some cases recovering views not seen for years. Some cities, most notably Milan, have decided that cyclists and pedestrians should have precedence over motorised traffic as the city reopens.

The mayors of Manchester and Liverpool have also called for a rethink, and urged the government against a return to “business as usual”. They want to keep some of the benefits we have seen from the pause in economic activity and advocate investment in walking and cycling infrastructure, and in retrofitting homes with renewable energy technology, thereby creating thousands of jobs.

The huge fall in the oil price could also work in favour of a greener economy, especially if oilfields have to be shut down. Of course, cheap oil is also a risk, as it could persuade people to choose fossil fuels over renewables. The fossil fuel companies will not give way without a fight, but they have already lost their social licence and the divestment campaign is starting to hurt their finances.

The Financial Times believes coronavirus could pave the way for a major change in political direction, with the pandemic having underlined the huge inequalities in society. In a recent editorial, the paper said:

“Radical reforms — reversing the prevailing policy direction of the last four decades — will need to be put on the table. Governments will have to accept a more active role in the economy. They must see public services as investments rather than liabilities, and look for ways to make labour markets less insecure. Redistribution will again be on the agenda; the privileges of the elderly and wealthy in question. Policies until recently considered eccentric, such as basic income and wealth taxes, will have to be in the mix.”

Greening the economy will hardly look radical at all in that scenario.
